phase: 35_llm_equal_window_heights

**Phase 35 final verification pass — complete.** - Both task files (01, 02) already in `complete/`; verified the work in-tree: `#engines` = `grid cols-2`, `.strip` has no `align-items` (keeps `display: grid`, `gap: .85rem`, `auto-fit minmax(min(340px, 100%), 1fr)`), `.grid.items-start` rule + corrected comment intact, rewritten pin `test_llm_engine_windows_stretch_to_a_common_row_height` in place. - Live re-verified in browser (fresh `35-llm-verify.cjs` run, screenshots re-captured): both engines answering; strip cards 456 px / panel cards 422 px with flat equal bottoms; row gaps 13.6 px (uniform `.85rem`); `n/a` cells preserved; 360 px viewport single-column, no overflow/clip. `/system` no-regress: `grid auto items-start`, expanded disclosure does not stretch collapsed siblings (325.4 → 325.4). - Completion criteria: served `/llm` markup ✓ · live equalized rows + screenshot ✓ · `/system` bytes unchanged ✓ · full suite/coverage/lint ✓ · README/AGENTS.md ✓ · no behaviour change (all existing pins pass) ✓. - Tests: `bash .agents/validate.sh` → **exit 0**: `uv run pytest --cov` **2031 passed, 19 skipped** (15 live + 4 store_perf, opt-in), coverage **98.71%** (94% floor reached); `ruff` all checks passed; `pyright` 0 errors; `node --check` + repo hygiene clean. - Live suite (`--live`, read-only): 4/15 pass (LLM engines); 5 fail solely on host-agent/upsd **connectivity timeouts** (9120/3051 unreachable from this machine — same errors as `dev-server.sh status`); environmental, no code defect. No live changes made (all verification read-only). - Docs: README.md reviewed in full — verified quickstart, installer/agent flags, config defaults, Containerfile facts, script flags, fixtures, test files, polling cadences: **consistent, no changes needed**. AGENTS.md: fixed one stale statement (hermetic skip count "12 live" → "15 live"); nothing else stale. - Dev server up (pid 811266), `/api/health` 200; hosts/upsd DOWN is the pre-existing environmental state, LLM source ok. - Next pending phase: **none** — `todo/` contains only this phase (35).

+# Phase 12 — A passed battery self-test is news, not a warning
+
+**Source:** `TODO.md` L3 — ""Last self-test: Done and passed" still shows up as a warning in the overview and UPS section"
+**Story:** n/a
+**Context:** `src/dashboards/sources/nut.py` (`assess()` — the explicit `health.checks[]` list, the "Last self-test" check at the `test_result` branch), `src/dashboards/alerts.py` (the overview alert rule that reads `health.checks[]`), `tests/test_nut.py` (the two existing "Last self-test" assertions, the `SimUps` test-result tests), `tests/fixtures/nut_apc.vars` / `nut_cyberpower.vars` (verbatim `LIST VAR` captures), `src/dashboards/sources/nut_sim.py` (the simulator's `PASSED`/`FAILED` window), `src/dashboards/web/pages/ups.html` + `src/dashboards/web/static/page-ups.js` (the check list the `/ups` card renders), `data/logs/` (screenshots)
+
+## Objective
+
+The `Last self-test` check grades the driver's own word about the last battery test, and a
+passed test — the real drivers answer **`Done and passed`** — must read `ok`, not `warn`.
+The current word lists (`"ok", "passed", "pass", "completed"` / `"failed", "fail", "error",
+"aborted", "test incomplete"`) let the one phrasing this fleet's hardware actually uses fall
+through to `warn`, so a *healthy* UPS carries a warning on the overview and the UPS page.
+After this phase the verdict follows the test's outcome: pass → `ok`, fail → `fail`,
+never-tested / unset → `unknown`, and the overview's alert feed stops naming it.
+
+## Dependencies
+
+- `05_ups_hero_battery_glyph` (complete) — the `health.checks[]` contract and the `/ups`
+  check list this phase changes.
+- `11_admin_login` (todo) — **no shared files**: 11 touches `app.py`/`config.py`/`store.py`/
+  the auth surface; this phase touches `sources/nut.py` + its tests + fixtures. Either order
+  runs; the only coupling is the shared `tests/test_nut.py` — apply whichever runs second on
+  top of the file state at that time.
+
+## Tasks
+
+1. `01_pin_self_test_wording.md` — capture the real drivers' `ups.test.result` values and pin the current (wrong) verdict in a failing test, so the fix has a before/after.
+2. `02_verdict_map_for_test_results.md` — the `assess()` word map: pass phrasings → `ok`, fail phrasings → `fail`, "No test initiated"/unset → `unknown` (never `warn`); fixtures + `tests/test_nut.py` + the simulator's wording stay consistent.
+3. `03_no_false_warning_overview_and_ups.md` — end-to-end: a passed test produces no alert on `/api/summary` and an `ok` chip on `/ups`; pinned by API test and a live screenshot.
+
+## Testing & Quality
+
+- Unit: `tests/test_nut.py` — the full word map (each pass phrasing `ok`, each fail phrasing
+  `fail`, `No test initiated` and unset `unknown`, case/whitespace-insensitive), driven from
+  the verbatim fixture wording where it exists and synthetic `UpsReading`s elsewhere.
+- Integration: `tests/test_api.py` — a `health.checks[]` entry with a passed self-test
+  produces no alert in the `/api/summary` payload; a failed one does.
+- The `SimUps` test-result tests (`tests/test_nut.py`) keep passing: the simulator's
+  `PASSED`/`FAILED` window words were already in the right tiers.
+- Coverage: **>90%** on new/modified code; the overall gate (94%) must hold.
+
+## Completion Criteria
+
+- [ ] `printf 'LIST VAR apc ups.test.result\n' | nc <driveripper> 3051` (run from a host
+      that can reach upsd — the laptop still cannot, per the fleet facts) captured and

+# Task 01 — Pin the self-test word the real drivers use
+
+**Phase:** `12_nut_self_test_verdict` · **Source:** `TODO.md:3` — ""Last self-test: Done and passed" still shows up as a warning in the overview and UPS section"
+
+## Objective
+
+Prove the bug in a test before touching the fix: the `Last self-test` check in
+`assess()` must be shown to grade the drivers' real wording (`Done and passed`) as
+`warn`, and the verbatim `ups.test.result` value must be captured from the running
+upsd so the fixture/test asserts the hardware's actual sentence, not a memory of it
+(AGENTS.md rule 7 — verify against the deployed upstream; the factory state both UPSes
+answer is `No test initiated`, pinned in `AGENTS.md`'s fleet facts).
+
+## Work
+
+1. `tests/test_nut.py` — add the pinning test **first**: build the `UpsReading` the way
+   the two existing "Last self-test" tests do (the `SimUps`/`vars` helpers in the file),
+   with `test_result="Done and passed"`, and assert the current behaviour
+   (`check["status"] == "warn"`) with a comment that the *fix* flips it to `ok`. This is
+   the red test the whole phase turns green.
+2. Capture the real value — from a host that can reach upsd (the laptop cannot yet,
+   per the fleet facts; `driveripper` itself, or the deployed dashboard's network):
+   `printf 'LIST VAR apc ups.test.result\nLIST VAR cyberpower ups.test.result\n' | nc
+   <upsd-host> 3051` — record the exact words in `tests/test_nut.py` (an assertion per
+   UPS where the value is a stable driver constant) and note the capture date. If a test
+   has been run on the hardware, the value is the driver's pass word; if not, it is
+   `No test initiated` — either way it goes into the test, because the verdict map must
+   cover both.
+3. `tests/fixtures/nut_apc.vars` / `nut_cyberpower.vars` — if the live `ups.test.result`
+   line differs from the captured fixture (a test has since run), re-capture with
+   `./scripts/capture-fixtures.sh` (the script scrubs serials; the test-result line is
+   not a secret) so the fixtures stay verbatim ground truth.
+4. Confirm the symptom end-to-end while it is live: `curl -s
+   http://127.0.0.1:8090/api/summary` (signed in, per phase 11) shows the alert row for
+   the `Last self-test` check, and `/api/ups/snapshot`'s `health.checks[]` carries the
+   `warn` entry — the two surfaces the TODO names.

+# Task 02 — Grade the test outcome, not the phrasing
+
+**Phase:** `12_nut_self_test_verdict` · **Source:** `TODO.md:3` — ""Last self-test: Done and passed" still shows up as a warning in the overview and UPS section"
+
+## Objective
+
+The `Last self-test` branch in `assess()` maps the driver's word to a verdict with two
+hardcoded tuples, and any phrasing outside both falls through to `warn` — which is how
+`Done and passed` (the real drivers' pass word) and `No test initiated` (the factory
+state) both read as warnings. Rewrite the branch as an explicit outcome map: pass
+phrasings → `ok`, fail phrasings → `fail`, "no test has run" phrasings and unset →
+`unknown`. A warning for a *passed* test is the bug; a warning for a machine that never
+ran a test is noise this phase removes too.
+
+## Work
+
+1. `src/dashboards/sources/nut.py` — the `test_result` branch in `assess()`:
+   - pass tier: the existing `("ok", "passed", "pass", "completed")` **plus**
+     `done and passed` (the live word captured in task 01, kept lowercase/trimmed —
+     keep the existing `strip().lower()` normalisation);
+   - fail tier: unchanged (`"failed", "fail", "error", "aborted", "test incomplete"`);
+   - new `unknown` tier: `no test initiated` (and the empty-string case) — reuse the
+     existing `None`-branch sentence ("no self-test result reported — run a battery
+     test") so the two "never tested" states say the same thing;
+   - the fall-through for any *other* phrasing stays `warn` (an unrecognised word is
+     the one thing worth a warning — a driver inventing a new word is drift worth
+     noticing), and the check keeps printing the raw word plus the `test_date` suffix.
+   - ASSUMPTION: `No test initiated` (the factory state on both UPSes, per AGENTS.md
+     fleet facts) maps to `unknown`, not `warn` — a pack that has never been
+     self-tested is a suggestion to run one, not a fault; the `None` branch already
+     says exactly that, so the two states read identically.
+2. `tests/test_nut.py` — the task-01 red test now asserts `ok`; add the full map:
+   every pass phrasing (including the captured live word) → `ok`, every fail phrasing
+   → `fail`, `No test initiated` / empty / unset → `unknown` with the run-a-test
+   sentence, an unknown phrasing (e.g. `mystery`) → `warn`; case and whitespace
+   variations of the live word.
+3. `tests/fixtures/nut_apc.vars` / `nut_cyberpower.vars` — if the captured live value
+   (task 01) is the factory `No test initiated`, the fixtures already carry it; if a
+   test has run, the fixture carries `Done and passed` — either way the fixture-driven
+   tests in `tests/test_ups_contract.py` / `test_nut.py` must pass against the new map
+   (the fixture's word is part of the hero contract's check list).
+4. `src/dashboards/sources/nut_sim.py` — no code change expected: the simulator's
+   `PASSED` / `FAILED` window words are already in the pass/fail tiers; run the
+   `SimUps` test-result tests to prove it. If the simulator ever answers a *third*
+   word, add it to the map — do not special-case the simulator.
+
+## Testing & Quality
+
+- Unit: the full word-map table in `tests/test_nut.py` (the tiers above, plus
+  `test_date` suffix still printed on the pass/fail detail line).
+- Regression: every pre-existing `test_nut.py` / `test_ups_contract.py` test passes
+  unmodified in intent (the fixtures' words land in the right tier).
+- Coverage: **>90%** on this task's new/modified code.

+      task-01 test now asserting `ok` for `Done and passed`
+- [ ] no phrasing the two real drivers answer (verified against the task-01 capture)
+      falls into `warn`

+# Task 03 — No false warning on the overview and the UPS page
+
+**Phase:** `12_nut_self_test_verdict` · **Source:** `TODO.md:3` — ""Last self-test: Done and passed" still shows up as a warning in the overview and UPS section"
+
+## Objective
+
+Prove the fix end-to-end on the two surfaces the TODO names: a passed self-test must
+produce **no alert** in `/api/summary` (the overview's Warnings panel) and an `ok`
+entry in `/api/ups/snapshot`'s `health.checks[]` (the `/ups` check list), while a
+*failed* test still alerts — the check keeps its reason for existing.
+
+## Work
+
+1. `tests/test_api.py` — the alert-absence pin: an app (the shared `create_app`
+   test harness, `auth_contract` seeding) whose UPS payload carries a `Last self-test`
+   check with a passed word answers `/api/summary` with **no** alert row naming it
+   (the `alerts` list is the thing the overview renders — a row there is the warning
+   the TODO sees); the same harness with a `fail`-tier word **does** produce the
+   alert, so the test pins both directions.
+2. `src/dashboards/web/static/page-ups.js` / `src/dashboards/web/pages/ups.html` — no
+   code change expected (the check list renders `health.checks[]` verdicts verbatim);
+   verify the `ok` chip styling for the "Last self-test" row is the existing dim path
+   (`ok` stays quiet ink, per the shared verdict vocabulary). If the row needs no
+   markup, say so in the completion note — do not restyle.
+3. Live verification (AGENTS.md invariant 10 — UI changes are screenshotted): the dev
+   server (`./scripts/dev-server.sh status` first; the source must be `ok`), signed in
+   with the dev password:
+   - `curl -s http://127.0.0.1:8090/api/summary` — no `Last self-test` alert while the
+     live UPSes report a passed (or never-initiated) result;
+   - the `/` overview: Warnings & errors panel shows no self-test row;
+   - the `/ups` page: the "Last self-test" row renders the driver's word with the `ok`
+     (or `unknown`) class.
+4. `data/logs/` — `self-test-passed-overview.png` and `self-test-passed-ups.png`
+   (the overview with the Warnings panel visible, and the `/ups` card with the check
+   list visible). If the live UPSes are at the factory `No test initiated`, the
+   screenshots show the `unknown` dim state — the *absence of the warning* is the
+   point, in either state.
+   - ASSUMPTION: no battery test is run on the live hardware to force a `Done and
+     passed` state — a self-test puts real load on a battery things are plugged into,
+     which stays the operator's call (the AGENTS.md known-gaps rule). The hermetic
+   `fail`/`ok` pins in `tests/test_api.py` carry the behaviour; the live screenshots
+   carry whichever state the hardware currently reports.

+# Phase 13 — The LLM page: fleet spacing and an honest decode tok/s
+
+**Source:** `TODO.md` L4–L5 — "In the LLM engines page the 'fleet' section has no spacing between it and the engine summaries" / "Decode tok/s sometimes jumps unrealistically high, could be a calculation error"
+**Story:** n/a
+**Context:** `src/dashboards/web/pages/llm.html` (the `#banners`/`#fleet`/`#strip`/engines section stack), `src/dashboards/web/static/dash.css` (`.strip`, the `.fleet` block, the shared `.85rem` rhythm), `src/dashboards/rates.py` (`RateEstimator` — the one piece of mutable state in the app), `src/dashboards/sources/llm.py` (`parse_gufo_metrics`/`parse_vllm_metrics`, the `measured()` Δcounter/Δt cells), `src/dashboards/prom.py` (`scalar(agg="sum")` over label sets), `tests/test_rates.py` / `tests/test_llm_source.py`, `tests/fixtures/metrics_gufo.txt` / `metrics_vllm.txt`, `data/logs/` (findings + screenshots)
+
+## Objective
+
+Two defects on the `/llm` page, one phase. (1) The `#fleet` aggregate block and the
+`#strip` engine summaries sit flush — the page's shared `.85rem` vertical rhythm skips
+the two sections that have no inline margin, so the page reads as one unbroken wall
+above the engine panels. (2) The `decode tok/s` hero/chart occasionally prints values
+far above anything the engines can produce: the measured Δcounter/Δt path is keyed
+correctly by *name* (rule 2), but the *value* it diffs is a **sum over the label
+set**, and the estimator's window-empty fallback divides by a `dt` it never bounds —
+so a counter's carried value can leak into one interval's delta, or a stall can
+rescale the window. The fix keeps every number measured and labelled (`Δ<window>`),
+just makes the measurement honest.

+- `11_admin_login` (todo) — no shared files (this phase touches `dash.css`, `llm.html`

+## Tasks
+
+1. `01_fleet_strip_spacing.md` — restore the shared `.85rem` rhythm between `#fleet` and `#strip` (and above `#fleet` when no banners are shown) in `dash.css`; screenshot.

+3. `03_bounded_estimator_and_per_series_rates.md` — the `rates.py`/`sources/llm.py` fix: per-label-series diffing plus a bounded effective window, so a label-set change contributes zero and a stall contributes an `n/a`, never a spike.
+4. `04_live_stable_verification.md` — the dev-server proof: sustained watch of the live `decode tok/s` with its `Δ<window>` label, screenshots, fixtures re-captured if the live shape changed.

+# Task 01 — The gap between the fleet block and the engine summaries
+
+**Phase:** `13_llm_page_and_decode_rate` · **Source:** `TODO.md:4` — "In the LLM engines page the 'fleet' section has no spacing between it and the engine summaries"
+
+## Objective
+
+`#llm`'s top-level sections break the page's shared `.85rem` vertical rhythm:
+`#banners` ends with `margin-bottom:.85rem`, the engine section below `#strip` carries
+an inline `margin-top:.85rem`, but `#fleet` and `#strip` carry **no** margin at all —
+so the fleet block and the engine summaries sit flush (and, with no banners, the fleet
+block also sits flush against the page head). Restore the rhythm with two CSS rules;
+no markup or JS change.
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — in the fleet/strip section:
+   - `#strip { margin-top: .85rem; }` — the gap the TODO names (fleet → engine
+     summaries). Unconditional on purpose: when `#fleet` is `hidden` (the
+     below-two-engines case) the strip is the first visible section and still needs
+     the same top gap.
+   - `#banners:empty ~ #fleet { margin-top: .85rem; }` — the gap above the fleet block
+     *only* when no banner occupies the slot above it; with a banner present, the
+     banner's own `margin-bottom:.85rem` already is the gap (never two stacked gaps).
+   - The engine section's existing inline `margin-top:.85rem` stays (it already is the
+     strip → panels gap).
+2. `src/dashboards/web/pages/llm.html` — no change expected; if the executor finds the
+   sections are not siblings the way the markup suggests, fix the CSS selectors to the
+   actual structure rather than re-flowing the markup (the section order is a phase-07
+   contract).
+3. `tests/test_api.py` — pin the two rules on the served bytes (the existing dash.css
+   pin device: a test that fails if the rules are missing from the served stylesheet),
+   so a later "cleanup" that drops them fails a test.
+4. Screenshot (invariant 10): dev server up, `/llm` with **≥2 engines answering** (the
+   fleet block visible — below two engines it stays hidden and the fix is invisible),
+   full page top-to-bottom: `data/logs/llm-fleet-spacing.png`. If the live fleet cannot

+# Task 02 — Pin the decode-tok/s spike against the live upstream
+
+**Phase:** `13_llm_page_and_decode_rate` · **Source:** `TODO.md:5` — "Decode tok/s sometimes jumps unrealistically high, could be a calculation error"
+
+## Objective
+
+Rule 7: never guess the trigger. Before touching `rates.py`, confirm **which** mechanism
+produces the spike, from the stored history and the live engines, and record the
+findings in a file the fix task (03) and the verification task (04) both read.
+
+## Work
+
+1. Find the spikes in the stored history (the dev DB is the source of truth — AGENTS.md
+   known gap 4 records it at ~610 MB with a year of raw/1m/1h rollups):
+   `sqlite3 data/… "<db>" "SELECT ts, value FROM sample WHERE metric LIKE
+   'decode_tokens_per_second%' ORDER BY ts DESC LIMIT 40000"` — list the top-N values
+   and their timestamps. Note for each: which engine (`source`/`host`), and what the
+   neighbouring values look like (a one-poll spike vs a sustained step).
+2. For each spike, read the **provenance** of the cell that produced it — the payload
+   carries it (rule 2): `computed:Δ<series>/Δt` + `Δ<window>` (our estimator) vs the
+   engine's own gauge name (the native `decode_tokens_per_second_native` source string).
+   A spike from the *engine's* gauge is the engine's rolling average, not our math —
+   the fix there is a label, not a code change. `sqlite3` the engine's native gauge
+   series alongside to separate the two paths.
+3. For the estimator path, inspect the live exposure (from a host that can reach the
+   engines — the laptop can reach both, per the fleet facts):
+   - `curl -s <gufo>/metrics | grep -E "tokens_(predicted|generated)_total"` and the
+     vLLM equivalent — are the counters **plain** (as in `tests/fixtures/`), or
+     **labelled per slot/engine** in the live build? A label set that changes between
+     polls is the leading suspect: `prom.Prom.scalar(agg="sum")` sums whatever label
+     sets exist, so a series that appears with a carried cumulative value adds that
+     whole value to one interval's delta (a `value < samples[-1]` decrease would reset
+     the window — an *increase* from a new series does not).
+   - Cross-check the spike timestamps against `GET /slots` history (which slots were
+     starting/turning over) and the event feed (`/api/events`) for engine restarts in
+     the same minutes.
+4. Record the findings in `data/logs/NOTES-decode-spike.md`: the confirmed mechanism
+   (one of the candidates below, or a new one), the evidence (values, timestamps,
+   captures), and the fleet's physical decode ceiling for the task-04 comparison —
+   the observed max of the native gauge over 90d **and** the cards' spec ceiling
+   (R9700 / Strix Halo 8060S), so "unrealistically high" has a number attached.
+
+Candidates, in suspected order (the findings file must name the one that fired):
+   - (a) **label-set sum**: `scalar(agg="sum")` over a changing set of labelled
+     series — a new series' carried counter enters the delta as a one-interval spike;
+   - (b) **window-empty fallback**: `rates.py`'s `base = samples[-2]` when fewer than
+     two samples sit inside the span — the effective window is the gap to the previous
+     sample, unbounded above by 2×span (the trim keeps the last two however old);
+   - (c) **a lineage jump that is not a decrease**: a counter that restarts *above*
+     zero (a renamed/relabelled series resolving under the same key, a pre-loaded
+     counter) — `value < samples[-1]` never fires, so the carried value is diffed;
+   - (d) **the engine's own native gauge** (vLLM's `avg_*_throughput` rolling average) —
+     not our math; label-level fix only.
+
+## Testing & Quality
+
+- No code changes in this task — diagnostics only, with the findings file as the
+  artifact. If a candidate is confirmed hermetically reproducible, add the red test
+  here (a `tests/test_llm_source.py` / `tests/test_rates.py` test that fails on the

+# Task 03 — A rate that cannot be a carried counter
+
+**Phase:** `13_llm_page_and_decode_rate` · **Source:** `TODO.md:5` — "Decode tok/s sometimes jumps unrealistically high, could be a calculation error"
+
+## Objective
+
+Fix the confirmed mechanism from task 02, plus the two generic weaknesses that make
+any mechanism possible: a summed counter whose *label set* changes between polls, and
+an effective window the estimator never bounds. After this task, a delta that includes
+a carried counter value is impossible by construction — a new series contributes
+nothing until it has a baseline, a stalled window answers `n/a` for one poll instead of
+rescaling, and a jump that looks like a lineage break is confirmed over two polls
+before it is published. Every published number still carries its `Δ<window>` label and
+`source` string (rule 2).
+
+## Work
+
+1. `src/dashboards/prom.py` — expose the **per-label-set** view the fix needs (the
+   `series` map already holds them; `by_label` shows the shape): a `values_by_series`
+   (or reuse `values` with labels) accessor that returns `[(labels, value)]` per
+   resolved name, so the source can diff each labelled series individually. Keep
+   `scalar` untouched (the gauges still sum/avg/max the same way — a *gauge's* sum is
+   a real aggregate; only *counter* deltas may not mix series).
+2. `src/dashboards/sources/llm.py` — the `measured()` path (gufo's
+   `tokens_generated_total`/`tokens_prompt_total` and vLLM's
+   `generation_tokens_total`/`prompt_tokens_total`): resolve the per-label-set values
+   and run **each series through the estimator under its own key** (the key is the
+   resolved name *plus* its label set — `llamacpp:tokens_predicted_total{slot="2"}`),
+   then `rate = Σ per-series rates`, with the cell's `window` the max of the
+   contributing series' windows (the window label says the widest window actually
+   used). A series with no previous sample contributes 0 tokens this interval — never
+   its carried value. The `Δ<window>` label and the `computed:Δ…/Δt` source string stay
+   in the `provenance()` format the page already prints (the source string names the
+   resolved series, as today).
+   - ASSUMPTION: per-series diffing is the fix for candidates (a) and (c) — a
+     label-set change then changes *nothing* in the delta until the new series has two
+     samples, which is exactly the "a renamed counter starts a fresh window" doctrine
+     the estimator docstring already states, extended from names to label sets.
+3. `src/dashboards/rates.py` — the two generic bounds:
+   - **stalled-window bound**: in the `len(inside) < 2` fallback, accept `samples[-2]`
+     as the base only while its age is ≤ 1.5 × `span`; older than that, return
+     `(None, None)` for this poll — one `n/a` on the poll after a stall is the honest
+     answer (a 20-second window on a 10-second panel is a different claim), and the
+     next poll recovers normally. The existing `test_window_is_labelled_with_the_span_actually_used`
+     (a 9s fallback) keeps passing: 9s ≤ 15s.
+   - **jump confirmation**: a published rate ≥ 8× the previous poll's published rate
+     (previous > 0) is held — the previous value is repeated for one more poll, and the
+     jump publishes only if *confirmed* by the next interval; an unconfirmed jump is
+     dropped (the cell prints the held value, its `Δ<window>` label unchanged). This
+     suppresses a single-interval artifact without flattening a real burst: a genuine
+     step-up is confirmed one interval later and then publishes, and the confirmation
+     state is per-key in the estimator.
+   - ASSUMPTION: the 8×-over-previous threshold and the one-poll hold are the right
+     confirmation rule — a real LLM decode step (a batch of long outputs starting)
+     persists across a 10s interval, while a carried-counter artifact does not; the
+     thresholds are named constants at the top of the file so they can move without a
+     logic change.
+4. `tests/test_rates.py` — the pins: a stalled window (previous sample > 1.5×span old)
+   answers `(None, None)` for one poll and recovers; a jump ≥ 8× holds for one poll
+   and publishes when confirmed / drops when not; the pinned pre-existing tests all
+   pass unmodified.
+5. `tests/test_llm_source.py` — the label-set pin: two parses of a metrics text whose
+   counter series set differs between polls (a `{slot="2"}` series appears carrying
+   50 000) — the delta of the second poll contains **no** 50 000; the flat-counter and
+   counter-reset tests keep passing.
+

+## Work
+
+1. Dev server up and the LLM sources `ok` (`./scripts/dev-server.sh status`); record
+   the start time. Watch for at least one full poll-cycle cluster with traffic if the
+   engines are idle (the operator's own requests are the traffic — do **not**

+     log `decode_tokens_per_second` (value, `source`, `window`) per engine;
+   - then `sqlite3` the `decode_tokens_per_second` raw series for the same period and
+     confirm no stored value exceeds the task-02 ceiling.
+2. `data/logs/llm-decode-stable.png` — the `/llm` page showing the hero row with the
+   `Δ<window>` provenance tag, the strip card, and (when ≥ 2 engines answer) the fleet
+   block with the task-01 gap; a second screenshot if a real burst was observed
+   mid-watch (the confirmed-and-published path — the burst's `Δ` label visible).
+3. `./scripts/capture-fixtures.sh` — re-capture **only if** task 02 recorded a live
+   shape drift (a label set the fixtures lack); otherwise leave the fixtures
+   untouched and say so.
+4. `uv run pytest -m live --live` — the opt-in live suite (read-only per its rule;
+   the LLM engine tests skip when their source is unset). Record the tally in the
+   completion note (the fleet's transport gap means the host/disks live tests may

+# Phase 14 — The store: fast reads, short writes, no "database is locked"
+
+**Source:** `TODO.md` L7 — "Pages take forever to load and seem to lock up the database. Fix that."
+**Story:** n/a
+**Context:** `src/dashboards/store.py` (the `sample`/`event`/`meta` schema, `pick_res`, `history`, `series_names`, `stats`, `maintain`, the single `self._lock`, `busy_timeout=5000`), `src/dashboards/api.py` (the N-hosts × M-metrics history loops, `/api/metrics`, the polled `/api/health`), `src/dashboards/poller.py` (`add_many` on every successful poll — the write side that loses the `busy_timeout` race), `tests/test_store.py`, `tests/test_api.py`, `data/logs/` (the ~610 MB dev DB per AGENTS.md known gap 4 — the `store-error: OperationalError: database is locked` line)
+
+## Objective
+
+The page load time and the `database is locked` lines are one disease: the hot read
+paths of a 610 MB / 140 MB-WAL database are **full-table operations on every request**
+(`series_names()` scans for `DISTINCT metric`, the browser-polled `/api/health` runs
+`stats()` which counts the whole `sample` table, `pick_res()` pays three COUNT
+round-trips per series), while `maintain()`'s rollups are long whole-table write
+transactions that hold the WAL write lock long enough for a poller's `add_many` to
+outlive `busy_timeout=5000` and surface as the reported `store-error` (AGENTS.md
+known gap 4). This phase makes every hot path bounded (indexes, one grouped query,
+short-TTL caches) and every write short (windowed rollups, WAL checkpoint tuning),
+with timing budgets pinned as tests so a regression is a red test, not a slow page.
+
+## Dependencies
+
+- the foundation (complete) — `store.py`/`api.py`/`poller.py` as shipped; the rollup
+  and retention contract in AGENTS.md invariant 9.
+- `11_admin_login` (todo) — **shared files, run-order note**: 11 rewrites `api.py`
+  (the session gate) and adds `get_meta`/`set_meta`/`delete_meta` to `store.py`. Apply
+  this phase's `store.py`/`api.py` changes on top of the file state at the time it
+  runs; never restore a line the other phase owns. The two phases touch disjoint
+  *regions* (11: the meta helpers + the auth routes; 14: the query paths + the
+  maintain rollups) — the coupling is the file, not the logic.
+
+## Tasks
+
+1. `01_baseline_store_costs.md` — a production-shaped seeded store + the timing/EXPLAIN baseline for every hot path, recorded in `data/logs/`.
+2. `02_no_full_scan_on_hot_paths.md` — `series_names`/`stats` off the per-request full scan (bounded caches), `pick_res` to one grouped query, the N×M history endpoints to one grouped round trip.
+3. `03_windowed_rollups_and_wal_tuning.md` — `maintain()` rolls up only the window since `last_maintain`; WAL checkpoint + journal-size tuning so the 140 MB WAL stops growing between checkpoints.
+4. `04_budget_gates_and_live_proof.md` — the timing budgets pinned as tests, the live dev-server proof (page load measured, zero `store-error` over a watch window), docs updated.

+
+## Objective
+

+
+## Work
+
+1. `tests/test_store.py` — the seeded-store recipe (a fixture the budget tests of this
+   phase all reuse): an on-disk SQLite file (WAL, like production — the in-memory DB
+   hides the lock behaviour) seeded to the dev DB's *shape and retention semantics*
+   (`raw_keep_hours=48`, `minute_keep_days=30`, `hour_keep_days=400` — the
+   `SampleStore` defaults, i.e. what a 90 d chart actually reads: 1m/1h, never raw
+   beyond 48 h):
+   - ~3 hosts × ~30 series per host, 10 s cadence for the 48 h raw window;
+   - their 1m rollups for the 30 d window and 1h rollups for the 400 d window
+     (generated by calling `maintain()` — a few hundred MB, the dev DB's order of
+     magnitude, a temp file, never the dev DB itself: tests stay hermetic per the
+     AGENTS.md testing policy);
+   - ~2 000 event rows and the `meta` rows the app writes (`last_maintain` included).
+   The test asserts the row counts, not the wall time of seeding.
+   - ASSUMPTION: "production-shaped" means the dev DB's *shape and magnitude* (~610 MB,
+     per AGENTS.md known gap 4), reproduced in a temp file — the dev DB itself is
+     never opened by a test (tests stay hermetic, the AGENTS.md testing policy), and
+     a temp DB of the same shape is the honest substitute.
+2. Measure (a script or the test's `--store-perf` marker; record in
+   `data/logs/NOTES-store-perf.md` with the machine's specs):
+   - `store.series_names()` (what `/api/metrics` runs per call) — wall time +
+     `EXPLAIN QUERY PLAN` (expected: a full scan of `sample`);
+   - `store.stats()` (what the browser-polled `/api/health` runs) — wall time +
+     EXPLAIN (expected: a full COUNT scan of `sample` + `event`);
+   - `store.pick_res()` × 3 + `store.history()` for one 90 d window (what one chart
+     series costs) — wall time + EXPLAIN;
+   - the full `/api/system/history` request shape (3 hosts × 9 series — the
+     `tests/test_system_contract.py` table, 27 `_history` calls) through the test app
+     — total wall time;
+   - a `maintain()` run on the seeded store — the write transaction's wall time
+     (the lock-holding window; note the `to_hour` step already scans the *entire*
+     30 d 1m window on every run — the suspected long write) and the WAL file's
+     size before/after;
+3. Record the baseline table in `data/logs/NOTES-store-perf.md`: path, wall time,
+   EXPLAIN shape, and the wall time of the poller's `add_many` (a 30-sample insert)
+   issued **concurrently** with a `stats()`/`series_names()` call — the race known gap
+   4 describes, made visible as a number (how often does the insert wait, and does it

+**Phase:** `14_store_performance` · **Source:** `TODO.md:7` — "Pages take forever to load and seem to lock up the database. Fix that."
+
+## Objective
+
+Three per-request paths pay a whole-table price on a 610 MB database:
+`series_names()` (a `SELECT DISTINCT metric` scan, on every `/api/metrics` call),
+`stats()` (a `COUNT(*) GROUP BY res` over all of `sample` plus `event`, on every
+browser-polled `/api/health`), and the N-hosts × M-metrics history endpoints
+(`pick_res()` is three COUNT round-trips per series, so one `/system` chart request
+is ~108 serialized round-trips through the single `self._lock`). Make every hot path
+bounded: short-TTL caches for the two scanned answers, one grouped query where three
+stand, and one grouped round trip where N×M stand. The response shapes are byte-
+identical — only the cost moves.
+
+## Work
+
+1. `src/dashboards/store.py` — `series_names()`: an in-memory cache of the distinct
+   metric set (per `source`/`host` argument tuple, a 60 s TTL, invalidated on
+   `add`/`add_many`/`delete_series` via a dirty flag — a cache that outlives a write
+   answers "why is this chart empty" with yesterday's truth). `stats()`: cache the
+   `sample`/`event` counts the same way (30 s TTL) — the `/api/health` poll (the
+   browser's `app.js` masthead loop) must never run a full COUNT scan; `last_maintain`
+   stays read through `get_meta()` as today (the meta table is tiny; do not cache
+   what a three-row table costs nothing to read).
+2. `src/dashboards/store.py` — `pick_res()`: replace the three per-`res` COUNT queries
+   with **one** `SELECT res, COUNT(*) … WHERE … ts >= ? GROUP BY res` (the three
+   resolutions in a single index-range pass), same decision logic, same return value.
+3. `src/dashboards/api.py` — the four history endpoints' loops (system/disks/llm/ups —
+   the `[host, metric]` nesting in each) call `store.history()` per pair, which is
+   `pick_res()` (now 1 query) + the thinning query. Add the batched door in
+   `store.py`: `pick_res_many(hosts, metrics, span, max_points)` and
+   `history_many(hosts, metrics, span, max_points)` — one grouped COUNT over the whole
+   `host IN (…) AND metric IN (…) AND res IN (…) AND ts >= ?` range, and one
+   per-resolution thinning query (the per-series `LIMIT ?` tail-thinning kept by a
+   window function or a per-series subquery — the shape of each series' answer must
+   stay identical: ascending `(ts, value)`, `tail=True` semantics preserved). The
+   endpoints' response dicts are unchanged (the same series, the same order); the
+   `tests/test_api.py` pins are the contract.
+   - ASSUMPTION: one grouped round trip (plus one thinning query per resolution
+     present) is the target for the N×M endpoints — the alternative (N×M separate
+     queries, each now cheaper) leaves ~100 serialized round-trips on a 3-host request,
+     which on a 610 MB file is still the page-load tail; the grouped shape is the fix
+     the TODO asks for. The per-series thinning keeps `tail=True` (the "the chart must
+     have 'now'" docstring) exactly as today.
+4. `tests/test_store.py` — the pins: `series_names()`/`stats()` answer from cache
+   within the TTL (a write after the read invalidates `series_names`; `stats` expires
+   on the clock); `pick_res_many`/`history_many` equal the per-series answers on the
+   seeded store (the byte-identical-shape test); a cache hit makes a second
+   `series_names()` call measurably not scan (assert via a query-counter hook or the
+   wall-time budget of task 04).

+# Task 03 — A rollup that holds the write lock for seconds, not minutes
+
+**Phase:** `14_store_performance` · **Source:** `TODO.md:7` — "Pages take forever to load and seem to lock up the database. Fix that."
+
+## Objective
+
+`maintain()` is "safe to call every minute" and is idempotent — but on a real-sized
+store the `to_hour` step's `SELECT … GROUP BY` scans the **entire 30-day 1m window**
+on every run (and `to_minute` the entire 48 h raw window), and that GROUP BY is
+inside the one `with self._lock, self._db:` transaction: a multi-second write
+transaction that holds the WAL write lock long enough for a poller's `add_many` to
+outlive `busy_timeout=5000` and surface as the `store-error: OperationalError:
+database is locked` line (AGENTS.md known gap 4). Window each step to *what became
+due since the last run* — the idempotent `INSERT OR REPLACE` makes a slightly wider
+re-scan safe, so the window is a cost bound, not a correctness device — and tune the
+WAL so its 140 MB growth stops being a per-run surprise.
+
+## Work
+
+1. `src/dashboards/store.py` — `maintain()`, both rollup steps:
+   - read `last_maintain` through `get_meta()` **before** the transaction (the
+     existing `stats()` note applies: the meta read is outside the non-reentrant
+     lock);
+   - `to_minute`: the raw scan bound moves from `ts >= now - raw_keep_seconds` to
+     `ts >= max(now - raw_keep_seconds, last_maintain - MINUTE - 60)` — steady state
+     (a run per minute) scans ~one minute of raw rows; a missed interval scans the
+     catch-up window; a first run on a fresh DB (no `last_maintain` row) scans the
+     full retention window exactly as today;
+   - `to_hour`: the same pattern against the 1m rows (`ts >= max(now -
+     minute_keep_seconds, last_maintain - HOUR - 60)`). The `ts < now - {MINUTE|HOUR}
+     - 60` incompleteness guard stays — a bucket is still only rolled once its whole
+     window is in the past.
+   - the `DELETE … pruned` step is unchanged (the retention window is the correct
+     bound for a prune; it is `DELETE`s on indexed ranges, not a GROUP BY).
+2. `src/dashboards/store.py` — the WAL tuning in `__init__` (after the existing
+   pragmas): `PRAGMA wal_autocheckpoint = 1000` (the default 1000 pages ≈ 4 MB
+   auto-checkpoint is already the default — the 140 MB WAL means checkpoints lose to
+   the write rate; the real lever is the journal-size cap) and
+   `PRAGMA journal_size_limit = 67108864` (64 MB — the WAL stops growing past it;
+   checkpoints then truncate it). Keep `journal_mode=WAL` and
+   `synchronous=NORMAL` (the "a lost sample is fine, corruption is not" comment
+   stands); keep `busy_timeout=5000` — the fix is a shorter write, not a longer wait.
+   - ASSUMPTION: 64 MB is the journal-size cap — the dev DB's 140 MB WAL is the
+     measured "too big" (AGENTS.md known gap 4), 64 MB is the nearest power of two
+     below it, and the cap is a pragma, not a migration; if the live watch (task 04)
+     shows checkpoint truncation starving writers, the cap moves (named constant in
+     `__init__`, one-line change).
+3. `tests/test_store.py` — the pins:
+   - **windowing correctness**: seed a store, run `maintain()` (full window, no
+     `last_maintain` yet), advance time and add new 1m buckets, run `maintain()`
+     again — the second run's `to_hour`/`to_minute` scan (assert via the EXPLAIN/row
+     count hook, or a `sqlite3` trace) touches only the since-`last_maintain` window,
+     **and** the rolled 1m/1h values are byte-identical to a reference whole-window
+     rollup on the same data (the windowing must not change a single averaged value —
+     `INSERT OR REPLACE` idempotency is what makes this safe, prove it);
+   - **catch-up**: no `maintain` for 10 minutes, then one run — the 10 minutes of
+     buckets are all rolled (the wider window, not a gap);
+   - **the lock race**: the task-01 concurrent loop (a poller-style `add_many` during
+     a `maintain()` run) now completes with **zero** `OperationalError`s over the
+     100× loop (the baseline's wait count is the before, this is the after).
+
+## Testing & Quality

+# Task 04 — The budgets, and the dev server that proves them
+
+**Phase:** `14_store_performance` · **Source:** `TODO.md:7` — "Pages take forever to load and seem to lock up the database. Fix that."
+
+## Objective
+
+The "after" numbers, pinned as tests so a regression is red instead of slow: the
+task-01 baseline vs the fixed store, side by side in `data/logs/NOTES-store-perf.md`,
+plus the live dev-server proof on the real 610 MB DB — page loads inside budget, zero
+`store-error` events over a watch window (the known-gap-4 failure mode gone, not
+hidden), and the docs updated.
+
+## Work
+
+1. `tests/test_store.py` / `tests/test_api.py` — the budget tests (the task-01 recipe
+   on the seeded store; budgets are the task-01 baseline's *target* — record the
+   chosen numbers in the notes file with the reasoning):
+   - the full `/api/system/history` request (3 hosts × 9 series, 1 h and 90 d):
+     wall time budget (the 90 d case reads the 1m/1h rollups — the one that used to
+     be the page-load tail);
+   - `store.series_names()` / `store.stats()` second call (cache hit): wall time
+     budget, asserted to be a fraction of the first call's (the scan is gone);
+   - one 90 d `store.history()` call: wall time budget;
+   - the budgets are generous (2–3× the measured "after"), so a slower CI machine does
+     not flake red — the notes file records both the machine's specs and the margin.
+2. The live proof (AGENTS.md invariant 10 — the dev server stays up while work
+   happens, and a fix is screenshotted, not claimed; invariant 9 — the DB is the
+   volume's business in deployment, the dev DB is the test bench):
+   - `./scripts/dev-server.sh restart` (its `stop` waits for the old pid to die —
+     known gap 4's "two servers on one file" cause stays fixed), `status` shows the
+     sources;
+   - page loads: `curl -o /dev/null -s -w '%{time_total}'` on `/` and on the
+     history-heavy pages' API calls (signed in, per phase 11), five runs each,
+     recorded; the browser's `/llm` or `/system` page with a 90 d window selected is
+     the worst case — screenshot `data/logs/store-perf-live.png` (the page loaded,
+     the charts drawn, the masthead dots `ok`);
+   - the watch: ≥ 25 minutes of `./scripts/dev-server.sh logs` (longer than the
+     gap-4 baseline's "a few times an hour" rate) with **zero**
+     `store-error: OperationalError: database is locked` lines; the `store.stats()`
+     `event` count for `kind='store-error'` over the window is 0 (the `sqlite3`
+     check on the dev DB — read-only);
+   - the WAL file's size after the watch (the cap from task 03, in the real DB).
+   - ASSUMPTION: the watch window is 25 minutes against a "few times an hour"
+     baseline rate — enough to cover > 0.4 of the baseline's expected occurrences at
+     the mean rate; if the baseline was at the mean, a zero-count 25-minute window
+     already moves the needle, and the `sqlite3` event-table check over *the whole
+     dev DB's* `store-error` rows (not just the window) shows when the last
+     occurrence predates this phase.
+3. Docs: `README.md` — the *Configuration*/*Development* notes gain the two new
+   `PRAGMA`s' one-line "why" (the journal cap, and that it is a cap not a target);
+   `AGENTS.md` — known gap 4's entry is updated to record the fix (the windowed
+   rollups, the journal cap, the budget tests) and the gap's "what remains" line
+   (checkpoint starvation was never shown to be a cause — the controlled 25 s read
+   transaction produced none — so the entry's honest wording stays, with the
+   `database is locked` line now attributed to the rollup's write window). (The
+   AGENTS.md/README update is the phase's *normal work* per the repo's definition of
+   done — this instruction is for the phase's executor, not for the conversion.)

+# Phase 15 — Protected exporter web servers, auth by certificate
+
+**Source:** `TODO.md` L3 — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+**Story:** n/a
+**Context:** `agent/host_agent.py` (the stdlib-only exporter web server; today: a bearer token via `--token`/`--token-file`, refuses an off-loopback bind without one, `ThreadingHTTPServer`, the `resolve_token` idiom), `src/dashboards/config.py` (`Target`/`parse_targets` — token in URL userinfo, `https://` URLs already accepted; **no change needed**), `src/dashboards/collectors.py` (`fetch_snapshot`, the one `UpstreamError`, redacted display URLs, the one shared `httpx.AsyncClient` from the lifespan), `src/dashboards/app.py` (the `PAGES` dict with the settings-page comment, `build_hub`/`build_context`, the lifespan that builds `ctx.auth`), `src/dashboards/api.py` (`AppContext`, the gated-write + event pattern), `src/dashboards/store.py` (`get_meta`/`set_meta`/`delete_meta` — the only durable key/value state, home of `auth.*`), `deploy/install-agent.sh` (the token-file idiom `0640 root:agent-user`, the `ProtectSystem=strict` unit with no `RuntimeDirectory`, the `--status` probe), `tests/test_agent.py` (the in-process agent harness), `tests/test_collectors.py`, `tests/test_deploy_scripts.py`, `tests/test_api.py` (the route walk, the settings-page pin, the orphan-id audit), `src/dashboards/web/pages/settings.html` + `src/dashboards/web/static/page-settings.js` (the "a page, not a dashboard" pattern the new `/certs` admin page follows)
+
+## Objective
+
+Every exporter (host agent) web server is protected end-to-end by certificates the dashboard itself generates and manages: the dashboard holds a root CA in the `meta` table, signs its own client cert and each agent's server cert, the agent serves TLS with a per-path client-cert check (only the dashboard can read it), the dashboard dials `https://` with its client cert, and a new `/certs` admin page lists every cert with its expiry and status and triggers rotation, revocation, and bundle re-delivery. The operator's stated follow-up — firewalling upsd 3051 and talking to the agent only — is the motivation, not part of this phase. The agent's bearer-token mode stays a compatibility mode; the dashboard's own login is a separate auth domain and is untouched.
+
+**Scope (operator-confirmed):** "exporters" = the host agents this repo installs. gufo / vLLM / upsd are third-party services this repo does not deploy; their TLS (e.g. upsd `STARTTLS`) is a separate operator concern.
+
+## Dependencies
+
+- `14_store_performance` (todo) — **shared-file, run-order note**: 14 rewrites the hot paths in `store.py`/`api.py`; 15 only *adds* meta keys and new routes/pages. Apply on top of the file state at the time it runs; never restore a line the other phase owns.
+- `11_admin_login` (complete) — the session gate (invariant 12) for the new routes, the gated-write + CSRF + event pattern for the new `POST /api/certs/*`, the `meta` helpers, and the settings-page pattern `/certs` follows.
+
+## Tasks
+
+1. `01_cert_management.md` — `src/dashboards/certs.py`: the dashboard-managed root CA, client cert, per-agent server certs, revocation and reissue, all in `meta`; the `cryptography` dependency (dashboard-side only).
+2. `02_agent_tls.md` — `host_agent.py` TLS mode: one installed `--cert-bundle`, the per-path client-cert check, the bundle revocation list, `bundle_rev` in the snapshot; token mode unchanged.
+3. `03_collector_tls.md` — the dashboard dials `https://` agent URLs with its client cert, verifies against its root, refuses a revoked agent without dialing; error sentences stay redacted.
+4. `04_cert_api.md` — the gated `/api/certs` surface: list, per-host bundle, rotate, revoke, root-rotate; fixed-text events, no keys out of `meta`.
+5. `05_certs_admin_page.md` — the `/certs` admin page (the settings pattern): every cert with its expiry and status, issued vs deployed bundle rev, rotate/revoke/root-rotate actions, bundle download.
+6. `06_deploy_cert_bundle.md` — `install-agent.sh --cert-bundle` installs `/etc/dashboards-agent.certs` (`0600 root:agent-user`), the unit gains the flag + `RuntimeDirectory`, `--status` probes over TLS; the script pins move with it.
+7. `07_live_rollout.md` — the two live agents flip to TLS, `HOST_TARGETS` goes `https://`, the live suite + health table + screenshot prove it; the `driveripper` install procedure is documented.
+
+## Testing & Quality
+
+- Unit: `tests/test_certs.py` (new) — the whole lifecycle against a dict `MetaStore`, exactly how `tests/test_auth.py` does it.
+- Integration: `tests/test_agent.py` (the TLS handshake matrix against the in-process agent), `tests/test_collectors.py` (the `https` dial, the revoked refusal with a no-dial spy, the error sentences), `tests/test_api.py` (the `/api/certs` shapes, the gate/CSRF on the new writes, the served `/certs` page pins), `tests/test_deploy_scripts.py` (the new flags/files/permissions).
+- Live: task 07 (AGENTS.md invariant 10 — the dev server stays up; screenshots in `data/logs/`).

+# Task 01 — The dashboard owns a root CA and every cert it signs
+
+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+
+## Objective
+
+The certificate lifecycle becomes a pure, testable module: the dashboard generates a root CA once (idempotent across restarts), signs its own client cert and each agent's server cert, and supports reissue and revocation — all state in the `meta` table, exactly how `auth.py` keeps the verifier and the session secret.
+
+## Work
+
+1. `pyproject.toml` — add `cryptography` to `dependencies` (dashboard-side only; the agent stays stdlib-only) and run `uv lock`. Invariant 8: `uv pip list --outdated` empty afterwards.
+   - ASSUMPTION: `cryptography` is the only new dependency and it stays on the dashboard side; the agent (task 02) gains no third-party code — it loads the PEMs with stdlib `ssl`.
+2. `src/dashboards/certs.py` (new) — the whole lifecycle as pure functions over the three-method `MetaStore` protocol (the same protocol `auth.load_auth_state` uses, so this module imports nothing else from the package, and its tests use a dict):
+   - `ensure_certs(store, *, now: float | None = None)` → a frozen `CertsState` carrying the PEM text (`root_key`, `root_cert`, `client_key`, `client_cert`) plus the root/client `serial` + `not_after`. Reads the `meta` rows first; only generates and persists when missing (first boot); an existing row wins and is **never regenerated on restart** — regenerating on every start would rotate the CA and invalidate every installed agent bundle. `now` is injected (the module never reads a clock itself — the `auth.py` rule).
+   - meta keys (one concern per key, the `auth.*` precedent): `certs.root.key`, `certs.root.cert`, `certs.client.key`, `certs.client.cert`, `certs.agents` (one JSON object mapping `host name` → `{serial, not_after, status, bundle_rev, bundle, san}` — the bundle text is stored, so what the agent holds is byte-identical to what the API serves).
+   - Shapes: root CA self-signed, CN `dashboards-root`, **10 years**; client cert signed by the root, CN `dashboards`, **1 year**; agent server certs signed by the root, CN = the host name, **1 year**, `SAN` = the address(es) the dashboard dials for that host.
+     - ASSUMPTION: 10 y root / 1 y leaf lifetimes. No env seed for the root CA (unlike the admin password, the root key is a secret only the app needs to know, so it is auto-generated on first boot and merely persisted).
+   - `issue_agent_cert(store, state, name, san: list[str])` / `reissue_agent_cert(store, state, name, san)` — a fresh serial, `bundle_rev` +1 (1 on first issue), `status: "active"`, a fresh `bundle` (below). Idempotent per call — never issued on a read.
+   - `rotate_root(store, state)` — a fresh root CA + fresh client cert + every existing agent entry reissued (each `bundle_rev` +1): one action re-arms the whole fleet.
+   - `revoke(store, state, name)` — `status: "revoked"` (the serial stays on the denylist until a reissue gives the host a fresh identity; there is no "unrevoke" — reissue is the fix).
+   - the **bundle** (the install artifact, the TODO's "root certificate installed with each exporter"): one PEM text = the agent's server cert + the agent's key + the root CA *cert* (never the root key) + a `# BUNDLE-REV <n>` line + a `# REVOKED <serial>` line (one per revoked serial of the *current* root generation — a root rotation resets the list, since every cert is reissued anyway).
+   - ASSUMPTION: one client cert for the whole dashboard (the agent verifies "signed by our root", not a per-process identity); one agent entry per `HOST_TARGETS` name.
+   - invariant 6, the `auth.py` rule: no `logging` and no raise with anything interpolated — a malformed stored PEM is a fixed-text `RuntimeError` telling the operator to delete the `certs.*` meta keys (the shape of the auth reset), and nothing else.
+3. `src/dashboards/app.py` (+ the `AppContext` in `src/dashboards/api.py`) — the startup path builds `ctx.certs` (an `ensure_certs` read, the one-time bootstrap included) **before** `build_hub`, in both the owned-store (`build_context`) and the injected-store (lifespan) branches, through **one** helper so the two wiring sites cannot drift (the `build_hub` rule in AGENTS.md); the PEMs are written once to a private temp dir (mode `0600`, lives as long as the process) and the *paths* are what `AppContext.certs` carries for task 03's dialing.
+   - A `certs` whose stored PEM is malformed (a truncated `meta` row) is a fail-closed startup — a dashboard that cannot present its own credential must not start the loops (the `ctx.auth` rule, the one deliberate raise).
+
+## Testing & Quality
+
+- `tests/test_certs.py` (new) — a dict `MetaStore` (the `tests/test_auth.py` idiom):
+  - the first `ensure_certs` call persists exactly the five `certs.*` keys; the second is byte-identical (no regeneration — pin the `certs.root.cert` value);
+  - the parsed chain (`cryptography.x509` loaders) verifies: client → root, agent → root; the SAN list appears in the agent cert; the expiries match the assumed lifetimes (injected `now`);
+  - `reissue_agent_cert` bumps `serial` and `bundle_rev` and sets `status` active; `revoke` flips the status and puts the serial on the bundle's `# REVOKED` line; a reissue after a revoke gives a fresh serial that is *not* on the list;
+  - `rotate_root` reissues every agent entry (each `bundle_rev` bumped), the bundle carries the new root cert, and no stored value still contains the old root key;
+  - the bundle contains the agent cert + key + root cert + `# BUNDLE-REV` + the `# REVOKED` lines and **never** the root key (assert via the PEM header and a parsed-key mismatch);

+# Task 02 — The agent serves a protected TLS web server from one installed bundle
+
+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+
+## Objective
+
+`host_agent.py` gains a TLS mode that makes the web server protected by certificate: one installed bundle holds the server cert + key, the root CA, a bundle revision, and a revocation list; the agent requires a client cert signed by the root on every path except `/health` (mirroring the token-mode `/health` exemption, so an installer probe can reach `/health` with the CA only), and it reports the bundle revision it loaded so the dashboard can tell a stale bundle from a fresh one. The token mode is byte-identical to today.
+
+## Work
+
+1. `agent/host_agent.py` — stdlib only (an `ssl` import; no new third-party dependency):
+   - a new flag `--cert-bundle <file>` (env `AGENT_CERT_BUNDLE`): one PEM text containing the server cert, the server key, the root CA cert, a `# BUNDLE-REV <n>` line, and `# REVOKED <serial>` lines. `resolve_bundle(path) -> (context, bundle_rev, revoked: frozenset[str], error)` is a pure function (the `resolve_token` idiom): parse the PEM blocks by text, extract the three blocks, write them to a temp dir for `load_cert_chain` (into `/run/dashboards-agent` when present and writable — the unit's `RuntimeDirectory`, task 06 — else `tempfile.mkdtemp`), and build the context.
+   - The TLS context: `ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)`, `load_cert_chain`, `load_verify_locations(ca)`, `verify_mode = ssl.CERT_OPTIONAL` — the handshake is optional and the **handler** enforces it: on every path except `/health`, `self.connection.getpeercert()` must carry a verified certificate (subject present), else `403 {"ok": false, "detail": "client certificate required"}`; that cert's serial must not be in the bundle's `# REVOKED` set, else `403 {"ok": false, "detail": "client certificate revoked"}`. The denylist file is re-read on mtime change per request (a small file; a redeployed bundle takes effect without a restart — the reason the `# REVOKED` lines live in the bundle at all).
+   - The startup gate: off-loopback with neither a token nor a bundle → the existing exit-2 refusal (its message now names the bundle too); a bundle present → the off-loopback bind is allowed (the client cert is the protection); a token plus a bundle → the token check is skipped on the TLS path (the handshake is the auth).
+   - The snapshot payload gains two **additive** top-level fields in TLS mode: `tls: true` and `bundle_rev: <n>` (absent in token mode — an additive field never changes an existing shape); the `serve()` start line says `tls (client cert required, rev <n>)`.
+   - `AGENT_VERSION` 1.0.0 → 1.1.0; the docstring's deployment paragraph gains one line for the TLS mode (no flavour text — the AGENTS.md audit rule).
+   - ASSUMPTION: `CERT_OPTIONAL` + the per-path check (not `CERT_REQUIRED`) is what keeps `/health` probeable with the CA only — the installer's `--status` and the systemd probe (task 06) cannot present a client cert the installer does not hold, and a probe that cannot health-check is a dead install.
+   - ASSUMPTION: the agent never generates or renews certificates (stdlib cannot mint x509); the bundle is the artifact the dashboard signs and the installer places.
+2. `tests/test_agent.py` — the existing in-process harness (`serve()` in a thread on `127.0.0.1`, `urllib`/`ssl` clients), with a test CA + leafs generated by `src/dashboards/certs.py` over a dict store (no second generator):
+   - a client with a matching client cert → `/snapshot` 200 with `tls: true` and `bundle_rev` equal to the bundle's;
+   - a client with no cert → the handshake fails or a 403 on a non-`/health` path; `/health` still 200 with a CA-only context (the probe path);
+   - a client signed by a *different* CA → refused;
+   - a client whose serial is in the bundle's `# REVOKED` list → 403 "revoked"; rewrite the bundle file without the line (mtime change) → the same client is accepted on the next request (the denylist re-read);
+   - a token-mode agent (no bundle): the existing tests unchanged and green (byte-identical behaviour — no `tls`/`bundle_rev` fields);
+   - `resolve_bundle` error paths: a missing file, an empty file, a bundle missing the key block, a bundle missing the `# BUNDLE-REV` line (an error — a revless bundle is not one this app signed; ASSUMPTION: the `# BUNDLE-REV` line is mandatory).
+3. `deploy/` is untouched here (task 06); the non-systemd fallback (`tempfile.mkdtemp`) keeps dev and tests working.

+# Task 03 — The dashboard dials agents over https with its own client cert
+
+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+
+## Objective
+
+An `https://` `HOST_TARGETS` entry is now a certificate-authenticated dial: the dashboard presents the client cert task 01 gives it, verifies the agent against its own root CA, refuses a *revoked* agent before dialing (invariant 3's shape — a source it knows is dead says so without a network), and passes the agent's `tls`/`bundle_rev` through the `system` and `disks` payloads so task 05's page can compare the issued rev against the deployed one. Engines and token-mode agents are untouched.
+
+## Work
+
+1. `src/dashboards/config.py` — **no change** (an `https://` URL already parses; a TLS host carries no userinfo, and the userinfo token stays available for token-mode hosts).
+2. `src/dashboards/collectors.py` —
+   - a small frozen `AgentTls` dataclass: `verify: str` (the CA path), `cert: tuple[str, str]` (the client cert + key paths), `status: Callable[[], str]` — the `status` callable returns `"active"`/`"revoked"` from a **fresh** `get_meta("certs.agents")` read (a small-table `SELECT`, cheap at poll cadence, and phase 14's work keeps it off the hot paths; reading it live is what makes a runtime revocation take effect on the next poll without a restart).
+   - `fetch_snapshot(client, target, *, timeout=None, tls: AgentTls | None = None)`: when `tls` is given **and** `target.url` is `https://`, the request passes `verify=<ca path>` and `cert=(cert path, key path)` to `client.get` (httpx per-request overrides — the shared client dials both plain and TLS upstreams, so a per-client `verify` would poison the engine dials).
+   - Revocation before any network: `tls is not None` and `tls.status() == "revoked"` → `UpstreamError(f"{target.name}: agent certificate revoked")` **before** `client.get` — the poller's stale/last-good semantics then do the rest (invariant 4).
+   - A `403` from an agent gets its own honest sentence (the existing `401` branch keeps the token-mode wording): `f"{target.name}: agent refused the client certificate ({detail})"` with the `detail` from the agent's JSON (`client certificate required` / `client certificate revoked`), the redacted `display_url` (invariant 6) like every message in this function.
+   - `fetch_host_snapshot`/`fetch_disk_snapshot` pass the `tls` through; the per-host `AgentTls` is plumbed from `AppContext.certs` into the `host_jobs`/`disks_jobs` lambdas (a new optional `tls` parameter on both `*_jobs`, `build_hub` takes it — one call site per branch so the production and injected wiring cannot drift, the `build_hub` rule in AGENTS.md). `status` reads from the store the jobs already hold.
+3. `src/dashboards/app.py` (+ the `AppContext` in `api.py`) — `AppContext.certs` (task 01) exposes the temp-dir paths (`ca`, `client_cert`, `client_key`); `build_context` and the lifespan's injected branch build the per-host `AgentTls` objects **before** `build_hub`.
+4. `src/dashboards/sources/host.py` + `src/dashboards/sources/disks.py` — pass the agent's `tls`/`bundle_rev` snapshot fields through into the per-host payload (additive, the `degraded` idiom) so `/api/system/snapshot` and `/api/disks/snapshot` carry the deployed rev. **No** `severity` for a rev mismatch — a count is not a graded number (the fleet-header rule), the page colours nothing for it.
+

+# Task 04 — The gated /api/certs surface: list, bundle, rotate, revoke, root-rotate
+
+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+
+## Objective
+
+The API half of "the collector manages the certs": a signed-in operator can list every cert with its expiry and status, download the exact bundle an agent should hold, and trigger rotation / revocation / root rotation. The routes dial nothing (invariant 1's shape), are gated like every other write (invariant 12), and write fixed-text events — a key never leaves `meta` (invariant 6).
+
+## Work
+
+1. `src/dashboards/api.py` — the new routes (the middleware gates them by default; the route-walk test covers them for free):
+   - `GET /api/certs` — `{root: {serial, not_after}, client: {serial, not_after}, agents: [{name, serial, not_after, status, bundle_rev, deployed_bundle_rev, san}]}`. `deployed_bundle_rev` is the `bundle_rev` from the host's last `system` job payload (the same source `alerts.py` reads job states from); a host that never answered → `null`. Reads never issue (no side effects on a read — a `GET` that mints a cert is a surprise).
+   - `GET /api/certs/<name>/bundle` — the stored bundle text, `Content-Type: application/x-pem-file`, `Content-Disposition: attachment; filename="agent-<name>.bundle"` — byte-identical to what `certs.py` stored (the installer's input, task 06/07).
+   - `POST /api/certs/<name>/rotate` — a reissue (`certs.reissue_agent_cert`, the SANs taken from the configured `HOST_TARGETS` URL host(s) + the name); a `cert-rotated` event (a fixed message naming the host — no PEM, no key).
+   - `POST /api/certs/<name>/revoke` — `certs.revoke`; a `cert-revoked` event. The next poll refuses without dialing (task 03) — that is the enforcement; the event is the audit line.
+   - `POST /api/certs/root/rotate` — `certs.rotate_root`; a `cert-root-rotated` event; the response carries `{"ok": true, "restart_required": true}` — the client cert and CA are startup material, so a new root is fully in force at the next process start (the page, task 05, prints that; the honest constraint, not a hidden one).
+     - ASSUMPTION: a root rotation requires a dashboard restart to be fully in force (the client cert + CA load at startup); the API says so instead of pretending a hot-swap that does not exist.
+   - A `<name>` that is not a configured `HOST_TARGETS` name → `404 {"configured": false}` **without** issuing, dialing, or touching the store (invariant 3, the `/api/disks` gate shape, spy-pinned in `tests/test_api.py`).
+   - Every `POST` is a gated write: session + `Origin`/`Sec-Fetch-Site` + the cookie's `X-CSRF-Token` (the `POST /api/ups/command` test idiom — a tokenless write records nothing on the wire, with the token it does).
+   - invariant 6: no `meta` value (a key PEM) may appear in an `event` row, a `/api/health` field, or an error `detail`; the events carry the host name + the action in fixed text.
+2. `tests/test_api.py` — the signed-in harness (`tests/auth_client.py::sign_in`):
+   - `GET /api/certs` with zero / one / three configured hosts: the key paths pinned (the `/api/disks` pin idiom — a panel that retires can never shrink the payload);
+   - an unknown `<name>`: the `404` and the spies on `httpx.AsyncClient.get` and `collectors.fetch_snapshot` (the `tests/test_api.py` spy idiom) prove no network and no store write (a `meta` row count before/after);
+   - `POST rotate` → `bundle_rev` +1, a `cert-rotated` event row, the `meta` value changed, and the old serial is not on the new bundle's denylist;
+   - `POST revoke` → the status, the event, and (through task 03's path) the next `fetch_snapshot` for that host refuses without a dial (the spy);
+   - `POST root/rotate` → a fresh root serial, every agent reissued, `restart_required: true` in the body;
+   - `GET bundle` → the body byte-identical to the stored `meta` bundle, and a reissue changes the served bytes;
+   - the unsigned gate: the route-walk test (existing, automatic) plus one explicit unsigned `303`/`401` on `GET /api/certs` and a `POST` refusal (the `tests/test_auth_api.py` idiom).

+# Task 05 — The /certs admin page: every cert, its expiry, rotate, revoke, re-deliver
+
+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter." (operator addition: an admin page to see generated certs and expirations, trigger rotation, and revoke certs)
+
+## Objective
+
+A signed-in operator sees every cert the dashboard has generated — the root CA, its own client, and one per host — with its expiry and status, can rotate / revoke / root-rotate through task 04's API, and can download the exact bundle an agent should hold. The page follows `settings.html`'s precedent exactly: a page and not a dashboard — in `PAGES` (so it is a route), not in `.tabs`, linked from `.masthead-right`, with no `aria-current` on the tabs and no status dots.
+
+## Work
+
+1. `src/dashboards/web/pages/certs.html` + `src/dashboards/web/static/page-certs.js` (the `page-settings.js` idiom: the same `<head>` + masthead, `Dash.fetchJSON`, errors printed through `textContent`, a `confirm()` for destructive actions — the typed `DANGER` word is reserved for power cuts):
+   - the **Root CA** block: the CN, the serial, the expiry (a local timestamp **and** the time left, the settings session-display idiom), and the **Rotate root CA** button → `POST /api/certs/root/rotate` with a confirm dialog; the response's `restart_required` prints "restart the dashboard to activate the new root" (the API's own sentence, not an invented one).
+   - the **Agents** table: one row per configured `HOST_TARGETS` host (the `GET /api/certs` `agents[]`): the name, the serial, the `status` chip (`active` → `ok`, `revoked` → `fail` — a string-to-class map, the page never compares a number), the expiry (local timestamp + time left), the **issued** `bundle_rev` against the **deployed** `bundle_rev` (`n/a` when the agent never reported — a `null` verdict, uncoloured; issued > deployed → a neutral `stale` note, uncoloured — a count is not a graded number, the fleet-header rule), and the `san` list in mono.
+   - per-row actions: **Rotate** (a confirm → `POST …/rotate`), **Revoke** (a confirm that says it stops the dashboard trusting that host until a reissue and a re-delivered bundle — a fixed sentence from the page, not the API), and **bundle** (a plain `<a href="/api/certs/<name>/bundle">` — a signed-in `GET` needs no CSRF).
+   - a client-cert line (the serial + the expiry) — the one cert the agents check. It is **display-only**: no revoke button (a revoked client cert is a dashboard that reaches no agent — a footgun the page should not make easy); its rotation happens with the root.
+     - ASSUMPTION: the client cert is display-only on the page (no revoke control); revoking it is deliberately not offered from the UI.
+2. `src/dashboards/app.py` — `PAGES` gains `"/certs": "certs.html"` (the settings-page comment at the `PAGES` dict extends by one line of the same shape); a `Certs` link (a `⚷` glyph is acceptable) in `.masthead-right` of every page including `/settings`, next to `⚙ Account` — **outside** `.tabs` (the settings precedent, `tests/test_api.py::test_every_dashboard_page_links_to_settings` pins that structure; extend the pin, do not break it).
+3. `src/dashboards/web/static/dash.css` — reuse existing vocabulary only (`.chip`, the table/`.hero`-family styles present in `settings.html`); **no** new `:root` tokens (the `tests/test_api.py` pin fails a CSS rule that reaches for an undeclared token).
+4. `tests/test_api.py` — the served-page pins (the settings-pin idiom):
+   - the `Certs` masthead link on every dashboard page and on `/settings` (extend `test_every_dashboard_page_links_to_settings` into a two-link pin, or a sibling test);
+   - the served `/certs` HTML: the root block, the agents table container, the three action labels; the page's own tab structure carries **no** `aria-current` on any of the five (the settings pin, copied);
+   - the automatic audits cover the rest: every `id` the page keeps is referenced by `page-certs.js` (the orphan-id audit), no `Dash.severityFor` named (the existing pin), the deleted-flavour-text audit, the `no-store`/gate shape from the route walk.

+
+## Objective
+
+`deploy/install-agent.sh` can install the certificate bundle the same way it already installs the token — one file, the right owner and mode, the unit flag, a `--status` that proves the TLS path end-to-end — and `tests/test_deploy_scripts.py` moves its pins so a regression is a red test, not a dead agent.
+
+## Work
+
+1. `deploy/install-agent.sh` —
+   - a new flag `--cert-bundle <file>` (the operator already fetched it from `GET /api/certs/<name>/bundle` — task 04's surface; the script does not dial the dashboard, per its existing no-dial rule): validate the bundle before touching anything (a `python3` one-liner: three PEM blocks — server cert, key, CA cert — and a `# BUNDLE-REV` line; a bad bundle refuses with the reason, the `resolve_bundle` idiom).
+   - install to `/etc/dashboards-agent.certs` as `0600 root:$AGENT_USER` (the token-file idiom, with one line of the same comment explaining why the mode matters — the bundle holds the agent's key, so only root and the agent's own service user may read it); on re-run, replace it only if the flag is given (an existing bundle survives an unrelated re-run — the token-reuse idiom).
+   - the unit: when a bundle is installed, `ExecStart` gains `--cert-bundle /etc/dashboards-agent.certs` (the `--token-file` line stays — task 02's token check is skipped in TLS mode, so the harmless dual mode eases a rollout) and `RuntimeDirectory=dashboards-agent` (the unit's `ProtectSystem=strict` leaves the agent no writable file but this — the extracted PEM blocks live there; `PrivateTmp` already exists, so a non-systemd dev run falls back to `tempfile`).
+   - the `--status` probe: when the unit runs with a bundle, probe `https://127.0.0.1:$PORT/health` with a `python3 -c` `ssl` context that `load_verify_locations`-es the bundle's CA block and presents **no** client cert (task 02's `CERT_OPTIONAL` + the `/health` exemption is what makes this possible — the installer holds no client cert); a token-mode install keeps the plain `/health` probe. The probe is `python3` (the unit's own interpreter), never a new binary dependency (no `openssl` — one less thing to install on a host).
+2. `deploy/agent-sudoers` — **no** new line (the bundle travels through the same root installer invocation as the token file).
+3. `tests/test_deploy_scripts.py` — the new pins (the file's existing idiom: read the script, run it unprivileged so it exits before touching anything, and assert on the lines):
+   - `--cert-bundle` in the usage + the `/etc/dashboards-agent.certs` path with the `0600` and `root:$AGENT_USER` `chown` (assert the `install -m`/`chown` line);
+   - a `RuntimeDirectory=dashboards-agent` line in the unit when a bundle is installed (assert the conditional that emits it);
+   - the `--status` probe branch: the `python3` `ssl` one-liner for TLS, the plain probe for token mode;

+# Task 07 — The fleet runs TLS: install, flip, verify, document

+**Phase:** `15_agent_mtls` · **Source:** `TODO.md:3` — "I want all exporters to be protected web servers. The collector should generate and manage a root certificate that needs to be installed with each exporter. Use the certs as auth to each exporter."
+
+## Objective
+
+The two live agents (deskwork, gateway) present the dashboard-issued server cert and require the dashboard's client cert; the dashboard dials `https://`; the health table, the live suite, and a `/certs` screenshot prove it — and the still-missing `driveripper` install is documented to carry a bundle from day one.
+
+## Work
+
+1. **Fleet (operator root actions, the `deploy/agent-sudoers` grant):** for `deskwork` and `gateway`: `GET /api/certs/<name>/bundle` (a signed-in `curl`), `scp` the bundle to the host, `sudo ./deploy/install-agent.sh --cert-bundle <file>`, `systemctl restart dashboards-agent`, `./deploy/install-agent.sh --status` green over TLS. Record the exact commands + output in `data/logs/NOTES-agent-install.md` (an append to the file's existing per-host record; local evidence, not tracked, the AGENTS.md rule).
+2. **The flip:** `.env.dev` — the `HOST_TARGETS` entries become `https://<same address>:9120` (no userinfo — the cert is the auth; the token goes away for a TLS host), `./scripts/dev-server.sh restart`, `./scripts/dev-server.sh status` shows `host:deskwork ok`, `host:gateway ok`, `disks:deskwork ok`, `disks:gateway ok` (the two `driveripper` jobs stay `DOWN` — unchanged, the designed degradation).
+3. **Proof (invariant 10):** `uv run pytest -m live --live` — the host/disks tests over the `https` path; a `/certs` screenshot (the table showing both rows `active`, issued rev == deployed rev) **and** a `/system` screenshot (the host rows not dimmed) in `data/logs/`; a `data/logs/NOTES-verify.md`-style note: the `curl` codes (unsigned `/api/certs` refused, signed-in 200), one line for a wrong-CA client's handshake failure (the redacted URL only).
+4. **The `driveripper` procedure:** an append to `data/logs/NOTES-agent-install.md` — when the agent is finally installed (the outstanding operator action, the AGENTS.md fleet section), install the bundle in the same invocation (`sudo ./deploy/install-agent.sh --bind … --cert-bundle …`) and point `HOST_TARGETS` at `https://` from day one; a token-only install after this phase is a host the `https`-dialing dashboard cannot reach.
+5. **Docs (the AGENTS.md definition of done):** the AGENTS.md fleet section (the transport fact: the agent is now mTLS, the bundle file, the `/certs` page) + the commands section (the bundle-fetch line); a short "Protecting the agent" section in `README.md` (the operator's how-to: fetch the bundle, install, flip the URL — three sentences, no flavour).
+
+## Testing & Quality

+# Phase 16 — Pin the agent's scaled smart-pass budget
+
+**Source:** chat 2026-10-19 — the `driveripper` 16-drive host: the flat 20 s smart-pass
+budget truncates a 16-device pass (a real read takes ~30–80 s), and because the deadline
+resets each pass, the tail drives would have stayed `smart: null` every pass. The fix —
+budget = 20 s floor scaled to 5 s × disk count, an explicit override still winning — was
+applied to the working tree on 2026-10-19 (operator-confirmed, verified on 16/16 live
+drives). This phase pins that already-applied change with tests and documentation.
+**Story:** n/a
+**Context:** `agent/host_agent.py` (`_smart_pass` — the scaled `budget = max(SMARTCTL_BUDGET_SECONDS, self.smart_timeout_seconds * len(device_names)) when the default is in force, else the explicit override; the `pass budget of {budget:.0f}s exhausted` error line; the module docstring "5 s per device and a pass budget of 20 s scaled to the disk count"), `tests/test_agent.py::test_the_pass_budget_skips_the_rest_with_one_error` (sets `collector.smart_budget_seconds = 0.0` — the override-wins branch), `AGENTS.md` line 185 ("5 s per device / 20 s per pass / 240 s cache") and the `deploy/install-agent.sh` header comment (line 25 area, "bounded 5 s per device and 20 s per pass" if still present there), `README.md` line 94 ("20 s per pass, results cached 4 minutes")
+
+## Objective
+
+The smart pass budget scale-up that is already in the working tree is pinned: a test proves the *default* scales (16 devices → 80 s deadline, one device → 20 s floor, the exhaustion line names the scaled figure), the override-wins branch stays covered, and every doc that still says "20 s per pass" says the floor-scaled truth. No new behaviour — the code change is already deployed on `driveripper` and verified live.

+# Task 01 — Pin the scaled smart-pass budget
+
+**Phase:** `16_agent_smart_pass_budget` · **Story:** n/a
+
+## Objective
+
+The default smart-pass budget (20 s floor, scaled to 5 s × disk count) is proven by tests: the deadline actually moves with the disk count, the exhaustion error line names the *scaled* figure, and the existing override-wins branch (a test sets `smart_budget_seconds = 0.0`) keeps passing untouched. The code change is already in `agent/host_agent.py::_smart_pass` — this task adds the tests, it does not rewrite the code.
+
+## Work
+
+1. `tests/test_agent.py` — add a helper that builds the in-process collector with **default** smart attributes (do not touch `smart_budget_seconds`/`smart_timeout_seconds`) and a `smartctl` fake that records each device's deadline window, in the same style as `test_the_pass_budget_skips_the_rest_with_one_error` (which stays untouched):
+   - `test_the_pass_budget_scales_with_the_disk_count`: 16 device names → the last device's `smartctl` run happens with `left` (its deadline margin) consistent with a ~80 s budget (assert the deadline the code computes: `max(20, 5 × 16)`; the fake binary is instant, so assert via the recorded `min(left, 5.0)` timeout being 5.0 for a late device and the pass *not* truncating — every device got a `smartctl` run); 1 device name → budget 20 s (assert the recorded timeout is 5.0 and, with the fake made slow enough to exhaust a 20 s but not an 80 s budget in a *separate* case if feasible — if the harness cannot fake wall time, assert the computed `budget` expression via the error-line route instead: force exhaustion with a `time.monotonic` monkeypatch offset).
+   - `test_the_pass_budget_error_line_names_the_scaled_figure`: force exhaustion on 16 devices (monkeypatch the clock forward past the 80 s deadline between two device runs, as the existing test's `0.0` override does for its 0 s budget) → the error line reads `smart: pass budget of 80s exhausted, N disk(s) skipped` — the scaled figure, not the 20 s floor.
+2. `agent/host_agent.py` — **no code change expected.** If a test exposes a real bug in the already-applied change (e.g. the `== SMARTCTL_BUDGET_SECONDS` default check), fix it minimally and record the diff in the task's completion note; do not redesign.
+
+## Testing & Quality
+
+- Unit: the two new tests above + the untouched `test_the_pass_budget_skips_the_rest_with_one_error` (override wins: `0.0` still exhausts immediately on 3 devices with one error line)
+- Coverage: **>90%** on `agent/host_agent.py::_smart_pass`'s budget branch (the default-scaled path must now be exercised, not just the override)

+- [ ] `uv run pytest tests/test_agent.py -q` green: the two new tests, the untouched override test, and every pre-existing agent test

+
+**Phase:** `16_agent_smart_pass_budget` · **Story:** n/a

+# Phase 17 — The installer's broken device filter and the kernel-gate variant
+
+**Source:** chat 2026-10-19 — the `driveripper` install: the template's
+`DevicePolicy=strict` + `DeviceAllow` lines produced a **deny-all device filter** on
+kernel 7.2 (systemd resolves `DeviceAllow` globs by name against `/proc/devices`, where
+this kernel lists NVMe as `blkext` (major 259), so `nvme*` matched nothing and the whole
+device namespace was locked). The operator removed the lines by hand; the unit now also
+runs `User=root` + `CapabilityBoundingSet=CAP_SYS_RAWIO CAP_SYS_ADMIN` (kernel 7.2's
+unprivileged-passthrough gate — `data/logs/NOTES-driveripper-agent.md`). The template
+still ships the broken lines, `User=$AGENT_USER`, and an empty bounding set, and re-running
+the installer on `driveripper` would **clobber the working unit** (unconditional
+`cat > "$UNIT"`). This phase makes the template the single source of the working unit.
+**Story:** n/a
+**Context:** `deploy/install-agent.sh` (`do_install` — the unconditional unit heredoc with `DevicePolicy=strict` + nine `DeviceAllow` lines, the `PrivateDevices=false` rationale comment block, `User=$AGENT_USER`, `CapabilityBoundingSet=`, the `--bind/--port/--token/--rotate-token/--status/--uninstall` flag set), `tests/test_deploy_scripts.py` (the fake-root install sandbox `test_install_path_installs_into_its_own_paths_and_prints_the_token_once`, the token-file permission test, the `bash -n` + function-naming pins), `AGENTS.md` (the fleet bullet "The deployed unit has since diverged from the template in the three ways the SMART block below records", gap 10's "the template change is its own phase"), `README.md` (the install section, line ~46 `sudo deploy/install-agent.sh --bind <addr> --port 9120`)
+
+## Objective
+
+Re-running `deploy/install-agent.sh` on any host — including `driveripper`, with
+`--as-root --caps CAP_SYS_RAWIO,CAP_SYS_ADMIN --force` — produces the working unit: no
+`DevicePolicy`/`DeviceAllow` lines (device access falls back to DAC via the `disk` group
+ SELinux, the standard SMART-monitoring arrangement), the kernel-gate variant expressible
+by flags, and a re-run that would change an existing unit prints the diff and refuses
+without `--force`. The default install (dedicated user, empty bounding set) is otherwise
+byte-identical to what the template wrote before this phase.
+
+## Dependencies
+
+- `09_disks_smartctl` (complete) — the smart pass the unit exists to serve
+- `15_agent_mtls` (todo) — **shared-file, run-order note**: 15's task 06 adds `--cert-bundle`/`RuntimeDirectory` to the same `do_install`; apply on top of the file state at the time it runs, never restore a line the other phase owns. If 15 lands first, its new lines survive this phase's filter-line removal untouched.
+
+## Tasks
+
+1. `01_drop_the_broken_device_filter.md` — remove `DevicePolicy=strict` + all nine `DeviceAllow` lines and rewrite the rationale comment block
+2. `02_root_and_caps_flags.md` — `--as-root` and `--caps CAP1,CAP2` write the kernel-gate unit lines

+# Task 01 — Drop the broken device filter
+
+**Phase:** `17_installer_device_filter` · **Story:** n/a
+
+## Objective
+
+The template unit no longer carries `DevicePolicy=strict` or any `DeviceAllow` line, and the comment block that justified them is rewritten to say why the *absence* is the fix. The `PrivateDevices=false` line stays (explicit, default behaviour, and the rest of the lockdown is unchanged).
+
+## Work
+
+1. `deploy/install-agent.sh` — in the `do_install` unit heredoc: delete the `DevicePolicy=strict` line and all nine `DeviceAllow=…` lines (`/dev/null`, `/dev/zero`, `/dev/full`, `/dev/random`, `/dev/urandom`, `/dev/nvme*`, `/dev/sd*`, `/dev/vd*`, `/dev/sg*`).
+2. `deploy/install-agent.sh` — rewrite the comment block above `PrivateDevices=false` (the "The pseudo nodes are not decoration…" paragraph) to the new truth: **no device filter on purpose** — systemd resolves `DeviceAllow` globs by name against `/proc/devices` (fnmatch in `bpf_devices_allow_list_major`), where kernel 7.2 lists NVMe as `blkext` (major 259), so `nvme*` matched nothing and `DevicePolicy=strict` denied the *whole* device namespace (the `driveripper` install went deny-all, root included; `data/logs/NOTES-driveripper-agent.md`). Without the policy, device access falls back to DAC (the `disk` group the script already grants) + SELinux — the standard SMART-monitoring arrangement. Keep the one operational fact that survives: `PrivateDevices=false` is the default (a `true` sandbox with no `DeviceAllow` list is what dies at spawn with `status=208/STDIN` — keep that warning sentence, it is still why the line is written explicitly).
+3. `deploy/install-agent.sh` — the script's top-of-file header comment (line ~25: "the unit device-allows the disk nodes") → "the unit applies no device filter (kernel 7.2's `/proc/devices` name matching made the old `nvme*` glob deny-all); device access is DAC via the `disk` group + SELinux".
+
+## Testing & Quality
+
+- Integration: `bash -n deploy/install-agent.sh` clean (the existing pin covers it); a quick sandbox run (the `test_install_path_installs_into_its_own_paths_and_prints_the_token_once` pattern, run manually) shows no `DevicePolicy`/`DeviceAllow` in the written unit — the formal pins are task 04, this task keeps the change small and reviewable.

+**Phase:** `17_installer_device_filter` · **Story:** n/a
+
+## Objective
+
+The kernel-gate variant of the unit (what `driveripper` runs) is expressible from the template: `--as-root` writes `User=root` instead of `User=$AGENT_USER`, and `--caps CAP1,CAP2` (comma-separated, e.g. `--caps CAP_SYS_RAWIO,CAP_SYS_ADMIN`) writes `CapabilityBoundingSet=CAP1 CAP2` instead of the empty `CapabilityBoundingSet=` line. Both default off; a flag without its friend is refused with a message.
+
+## Work
+
+1. `deploy/install-agent.sh` — flag parsing: add `--as-root` (sets `AS_ROOT=1`) and `--caps <list>` (sets `CAPS="<list>"`, validates non-empty, rejects an empty list with exit 1) in the existing `case`/flag block, and `--help` text:
+   - `--as-root      run the service as root (for a kernel-gated host: kernel 7.2 gates unprivileged smartctl passthrough behind capabilities, not uid — a root process under the default empty bounding set is capability-less, so this flag needs --caps to mean anything)`
+   - `--caps LIST    CapabilityBoundingSet line for the unit (comma-separated, e.g. CAP_SYS_RAWIO,CAP_SYS_ADMIN); default: empty (capability-less service)`
+2. `deploy/install-agent.sh` — validation: `--as-root` without `--caps` → print "note: --as-root with the default empty CapabilityBoundingSet leaves the process capability-less (the kernel gates check capabilities, not uid); pair it with --caps for a kernel-gated host" and **still proceed** (a capability-less root is a legitimate, if unusual, choice — do not hard-refuse; the note is the operator's reminder). `--caps` without `--as-root` → refuse, exit 1 ("--caps needs --as-root: a capability grant on the service user is not the kernel-gate fix").
+3. `deploy/install-agent.sh` — the unit heredoc: `User=$AGENT_USER` → `User=$( [ "$AS_ROOT" -eq 1 ] && echo root || echo "$AGENT_USER" )`; the empty `CapabilityBoundingSet=` line → the `CAPS` list converted comma→space when set. Add one comment line above: `# --caps: kernel 7.2 gates unprivileged smartctl passthrough (NVMe admin log: CAP_SYS_ADMIN; SG_IO allow-list: CAP_SYS_RAWIO); a root process needs them named, because an empty bounding set bounds even root to CapEff 0`.
+4. `deploy/install-agent.sh` — the `--status` probe is unchanged (it probes the agent over HTTP; the user the unit runs as is invisible to it). The token file stays `0640 root:$AGENT_USER` — with `--as-root` the group read is irrelevant (root reads it), so do **not** change the token-file logic.

+2. `deploy/install-agent.sh` — in `do_install`, immediately before the `cat > "$UNIT"` heredoc write: build the would-be unit into a temp file (the heredoc already exists — render it once to `$(mktemp)`), and if `"$UNIT"` exists and `! cmp -s "$UNIT" "$tmp_unit"`:
+   - if `FORCE=1`: print the diff (`diff -u "$UNIT" "$tmp_unit"` on stdout) and proceed with the overwrite;
+   - else: print `refusing to overwrite $UNIT (generated unit differs); run with --force to apply:` + the same diff, and `exit 1` **before** the token-file write, the `systemctl daemon-reload`, and the `systemctl enable --now` — a refused run must leave the host exactly as it was (token file, unit, and running service all untouched; note the token-reuse logic runs earlier in `do_install` and only *reads* the existing token, so ordering the guard before the unit write is enough).

+   - `test_a_default_install_unit_is_the_pre_phase_unit_minus_the_filter_lines` — the sandbox-installed unit equals the known pre-phase template unit text minus the ten filter lines (pin the whole unit, so a future template line drift fails here).
+   - `test_as_root_and_caps_write_the_kernel_gate_unit_lines` — `--as-root --caps CAP_SYS_RAWIO,CAP_SYS_ADMIN` → `User=root` and `CapabilityBoundingSet=CAP_SYS_RAWIO CAP_SYS_ADMIN` exactly; `--caps` alone → exit 1 with the `--as-root` message; `--as-root` alone → proceeds with the capability-less note on stdout.
+   - `test_a_re_run_that_differs_refuses_without_force_and_applies_with_it` — the refuse/force/silent sequence (exit 1 + diff on stdout + installed unit untouched; `--force` overwrites with the diff printed; an unchanged re-run is silent).
+2. `AGENTS.md` — the fleet bullet's "re-running `deploy/install-agent.sh` on driveripper would clobber the working unit, because it rewrites the unit unconditionally (gap 10)" → the post-phase truth: the installer no longer writes the device-filter lines, and the `driveripper` unit is reproducible with `sudo deploy/install-agent.sh --bind 10.1.0.126 --port 9120 --as-root --caps CAP_SYS_RAWIO,CAP_SYS_ADMIN --force` (a re-run that would change an existing unit refuses without `--force`). Update gap 10's "the template change is its own phase" → "done in phase 17" with the flag line.

+# Phase 18 — Collapse the nav bar into a hamburger
+
+**Source:** `TODO.md` L3 — "The nav bar needs to collapse into a hamburger like brain of reese does"
+**Story:** n/a
+**Context:** the seven mastheads that carry the tab nav — `src/dashboards/web/pages/{index,system,disks,llm,ups,settings,certs}.html` (each has `nav class="tabs" aria-label="Dashboards"` with the five dashboard links; `login.html` deliberately has no tabs — it renders only the brand link and the theme toggle, and stays untouched), `src/dashboards/web/static/app.js` (`Dash.initChrome()`, called from the one `DOMContentLoaded` at line 786 — the `themeButton`/`clock`/`nav-status` blocks there are the per-element `if (element)` no-op pattern this phase's binding follows), `src/dashboards/web/static/dash.css` (`.masthead` at line 95 — `position: sticky; z-index: 40; height: var(--header-h)`, `nav.tabs` at line 131, the existing `@media (max-width: 640px)` block at line 286, the `prefers-reduced-motion` block at line 938), and the reference implementation the TODO names — `brain_of_reese` (sibling repo, read-only): `frontend/assets/header.js` lines 326–366 (the phase-46 binding: `#nav-toggle` shown ≤640px, `setNavMenu(open)` funnel, close on link click / Esc with focus return / `matchMedia` resize-back). Pinned test neighbours: `tests/test_api.py::test_the_disks_tab_is_in_the_masthead_of_every_page` (line 3837) and the served-page orphan-`id` audit in `tests/test_auth_api.py` (line 1654)
+
+## Objective
+
+On viewports ≤640px the masthead's five tab links collapse into a dropdown opened by a hamburger button, mirroring brain of reese's phase-46 behaviour: one shared binding in `app.js` (a no-op on any page without the elements — `/login`), the inline nav hidden and the dropdown absolutely positioned under the sticky masthead, and the desktop masthead byte-identical in behaviour above the breakpoint. The `masthead-right` cluster stays visible on phones; only the tab nav collapses.
+
+## Dependencies
+- — (none; builds on the shipped masthead, `initChrome`, and the 640px media block)
+
+## Tasks
+1. `01_hamburger_markup.md` — the `#nav-toggle` button and the `nav` id, identical across the seven tabbed pages, absent from `/login`
+2. `02_dropdown_css.md` — the ≤640px block: toggle visible, inline tabs hidden, `.is-open` dropdown under the masthead, two-row masthead
+3. `03_toggle_binding.md` — the `initChrome` binding: toggle + `aria-expanded`, close on link click / Esc / resize-back
+4. `04_tests_and_verification.md` — the pins (present on all seven, absent on `/login`, CSS and binding), the orphan-`id` audit, and the narrow-viewport browser verification with screenshots
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the served-page pins (see task 04); the existing masthead/tab pins (`test_the_disks_tab_is_in_the_masthead_of_every_page`, `test_every_page_links_to_both_admin_pages`) and the `tests/test_auth_api.py` orphan-`id` audit pass untouched — the new `id`s are referenced by `aria-controls`, the stylesheet, and `app.js`, so the audit must still clear
+- Coverage: **>90%** on new/modified code (the phase is markup + CSS + one small JS binding; the coverage gate applies to the changed Python test files)
+- The gate (`bash .agents/validate.sh`) includes `node --check` of `web/static` — the modified `app.js` must pass it

+
+- The final pass reviews `README.md` and `AGENTS.md` in full against the project as it stands after this phase — fixing every inconsistency found, **including pre-existing ones not caused by this phase**.
+- AGENTS.md's `UI conventions` section gains the masthead-collapsing convention (the 640px breakpoint, the toggle's identity, the close paths, and that `/login` carries no toggle) so a future masthead edit knows the contract. The README's page table is unchanged — the nav is the same five links at every width.

+# Task 01 — The hamburger button markup
+
+**Phase:** `18_nav_hamburger` · **Source:** `TODO.md:3` — "The nav bar needs to collapse into a hamburger like brain of reese does"
+**Story:** n/a
+
+## Objective
+
+The seven pages that carry the tab nav each gain the hamburger button and the `nav` id, so the (later task's) CSS and binding have stable anchors to work on. The markup is identical on every page, and `/login` — which deliberately renders only the brand link and the theme toggle — stays untouched.
+
+## Work
+
+1. `src/dashboards/web/pages/index.html` · `system.html` · `disks.html` · `llm.html` · `ups.html` · `settings.html` · `certs.html` — in each masthead, immediately before `nav class="tabs"`, add the toggle:
+   ```html
+   <button class="ghost nav-toggle" id="nav-toggle" type="button"
+           aria-expanded="false" aria-controls="nav-tabs" aria-label="Toggle navigation">☰</button>
+   ```
+   and give the nav its id: `<nav class="tabs" id="nav-tabs" aria-label="Dashboards">`. The button sits between `.brand` and `nav.tabs`, inside the same `<header class="masthead">` — one element per page, no script changes in this task.
+2. `src/dashboards/web/static/dash.css` — add the one base rule beside the other `button.ghost, a.ghost` family (the masthead section): `.nav-toggle { display: none; }` — the button is invisible on every width until task 02's ≤640px block shows it, so the project stays exactly as it looks today after this task.
+3. `src/dashboards/web/pages/login.html` — **no change.** Verify by `grep -c 'id="nav-toggle"'` returning 0 (the pin lands in task 04).
+4. `ASSUMPTION:` the TODO named brain of reese's behaviour, not its breakpoint or glyph. This task takes the 640px breakpoint (brain's `(max-width: 640px)` and `dash.css`'s existing 640px block) and the `☰` glyph with `aria-label="Toggle navigation"`; the CSS task owns the visual.
+5. `ASSUMPTION:` only the tab nav collapses on phones. The `masthead-right` cluster (`#nav-status` dots, pause, `⚷ Certs`, `⚙ Account`, theme toggle) stays visible; the masthead wraps to two rows at ≤640px (task 02).
+
+## Testing & Quality
+- Integration: the served pages still pass the untouched masthead pins (`test_the_disks_tab_is_in_the_masthead_of_every_page`, `test_every_page_links_to_both_admin_pages`) and the orphan-`id` audit — `#nav-toggle` is referenced by the (task 02) stylesheet rule and `aria-controls`, so the audit must not flag it
+- Coverage: **>90%** on modified code (HTML only — the gate's `node --check` and pytest suite are the checks)

+# Task 02 — The ≤640px dropdown CSS
+
+**Phase:** `18_nav_hamburger` · **Source:** `TODO.md:3` — "The nav bar needs to collapse into a hamburger like brain of reese does"
+**Story:** n/a
+
+## Objective
+
+The CSS that makes the hamburger real at ≤640px: the toggle button visible, the inline tab nav hidden, the `.is-open` nav rendered as a dropdown under the sticky masthead, and the masthead wrapping to two rows so the `masthead-right` cluster does not overflow a phone. Above 640px nothing changes.
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — the base `.nav-toggle { display: none; }` rule already landed with task 01's markup (the button is invisible on every width until this task's block). Extend the existing `@media (max-width: 640px)` block at line 286 (or add a sibling block — the file's convention is one block per concern; a `/* mobile nav */`-commented block beside the masthead section is the cleaner home):
+   - `.masthead { height: auto; min-height: var(--header-h); flex-wrap: wrap; }` — the single-row fixed-height masthead cannot hold brand + toggle + the whole `masthead-right` cluster at 360px; two rows, first row brand + toggle, second row the cluster.
+   - `.nav-toggle { display: inline-flex; align-items: center; }` (it is a `button.ghost`, so the outlined style is inherited — no second palette, the file's rule).
+   - `nav.tabs { display: none; }` and `nav.tabs.is-open { display: flex; flex-direction: column; gap: 0; position: absolute; top: 100%; left: 0; right: 0; background: var(--bg-raised); border-bottom: 1px solid var(--border); box-shadow: 0 8px 24px rgba(0, 0, 0, .35); padding: .4rem; z-index: 41; }` — the dropdown. The masthead is `position: sticky`, which is a non-static containing block for its absolute descendants, so `top: 100%` pins it directly under the (wrapped, two-row) masthead. `z-index: 41` is one above the masthead's 40 so the dropdown sits on the page content.
+   - `nav.tabs.is-open a { padding: .6rem .7rem; border-radius: var(--radius-sm); }` — touch-sized rows; the existing `:hover`/`[aria-current="page"]` rules carry over unchanged.
+   - Optional at most: a 120ms opacity/translateY transition on `nav.tabs.is-open`, **disabled inside the existing `@media (prefers-reduced-motion: reduce)` block at line 938** (add the dropdown selector to that block's list of motion-killers if used). If in doubt, ship without the transition.
+2. `ASSUMPTION:` the dropdown is a single full-width column under the masthead (brain's shape, adapted: brain hides the nav in a `#app-nav` container; here the `nav` element itself is the container and gets `id="nav-tabs"` + `.is-open`). No separate menu panel element.
+3. `ASSUMPTION:` no `body`-level marker class (brain's `nav-menu-open` exists for its sticky bottom chat cluster, which the dashboards do not have — the dropdown competes with nothing; do not copy a side effect nobody needs).
+
+## Testing & Quality
+- Integration: the served-stylesheet pins land in task 04 (base rule present, ≤640px block contains the toggle-visible + tabs-hidden + `.is-open` rules); the untouched `node --check` gate passes (CSS is not checked, but confirm no syntax error by loading the page in the browser — task 04's verification)
+- Coverage: **>90%** on modified code (CSS only; the gate's pytest/ruff/pyright must stay green)

+# Task 03 — The toggle binding in `initChrome`
+
+**Phase:** `18_nav_hamburger` · **Source:** `TODO.md:3` — "The nav bar needs to collapse into a hamburger like brain of reese does"
+**Story:** n/a
+
+## Objective
+
+One shared binding in `app.js` (the file every page loads, including `/login`) that makes the button work on all seven tabbed pages and is a no-op where the elements are absent. The behaviour mirrors brain of reese's phase-46 binding: a `setNavMenu(open)` funnel so no close path can leave the state stuck, `aria-expanded` honest at all times, close on link click, on Esc (focus returns to the button), and on resize back above the breakpoint.
+
+## Work
+
+1. `src/dashboards/web/static/app.js` — inside `initChrome()` (line 620), after the `nav-status` block and before the `return`, add a block in the file's per-element guard style (the `themeButton` pattern at line 626 is the shape: `if (element) { … }`):
+   ```js
+   const navToggle = $('#nav-toggle');
+   const appNav = $('#nav-tabs');
+   if (navToggle && appNav) {
+     const setNavMenu = (open) => {
+       appNav.classList.toggle('is-open', open);
+       navToggle.setAttribute('aria-expanded', open ? 'true' : 'false');
+     };
+     navToggle.addEventListener('click', () =>
+       setNavMenu(!appNav.classList.contains('is-open')));
+     // A link click navigates — shut the menu (event-delegated: the five
+     // links are static markup, so one listener on the nav covers all of them).
+     appNav.addEventListener('click', (event) => {
+       if (event.target.closest('a')) setNavMenu(false);
+     });
+     // Esc closes while open; focus returns to the opener.
+     document.addEventListener('keydown', (event) => {
+       if (event.key === 'Escape' && appNav.classList.contains('is-open')) {
+         setNavMenu(false);
+         navToggle.focus();
+       }
+     });
+     // Resize back to desktop: the inline nav reappears — drop the open state
+     // so aria-expanded stays honest (the CSS hides the dropdown above 640px
+     // regardless, but a stuck `is-open` would re-open on the next shrink).
+     const mq = window.matchMedia('(max-width: 640px)');
+     const onMqChange = () => { if (!mq.matches) setNavMenu(false); };
+     if (mq.addEventListener) mq.addEventListener('change', onMqChange);
+   }
+   ```
+   Notes: the breakpoint literal must match task 02's CSS block — if one drifts, the menu opens into a display:none nav. `ASSUMPTION:` that match is pinned by task 04's served-asset test (assert the `640px` literal appears in both the served stylesheet's nav block and the served `app.js`), not by a shared constant — the file's convention is per-file literals (the 640px in CSS, 900px for the clock, and the page scripts' own numbers do not share a constant either).
+2. No `body`-level marker class (task 02's assumption carries: nothing on this app competes with the dropdown for taps, so brain's `nav-menu-open` marker is not copied).
+3. No change to the login page: `initChrome` already ships to it, and the `if (navToggle && appNav)` guard is the no-op — verify in task 04 that `/login`'s served script is the same shared file (it is: every page loads `/static/app.js`) and the guard makes the binding inert there.
+
+## Testing & Quality
+- Integration: the binding's behaviour is verified in the browser (task 04 — the repo has no JS test runner; the pins are structural on the served bytes: the block is present in the served `app.js`, the four close paths named in a comment, `node --check` passes); the untouched Python suite stays green
+- Coverage: **>90%** on modified code (one JS function; the Python coverage gate applies to the test files task 04 adds)

+# Task 04 — Pins and narrow-viewport verification
+
+**Phase:** `18_nav_hamburger` · **Source:** `TODO.md:3` — "The nav bar needs to collapse into a hamburger like brain of reese does"
+**Story:** n/a
+
+## Objective
+
+The phase is pinned on the served bytes the way this repo pins every page surface: the button is on all seven tabbed pages and **absent** from `/login`, the CSS and the binding carry the matching 640px literal, and the orphan-`id` audit still clears. Then the designed degradation is proven in a real browser at a phone width — the invariant-10 screenshot pass.
+
+## Work
+
+1. `tests/test_api.py` — new tests, in the style of `test_the_disks_tab_is_in_the_masthead_of_every_page` (line 3837; it iterates the served pages and checks the masthead):
+   - `test_the_nav_toggle_is_in_the_masthead_of_every_tabbed_page`: for each of the seven served pages (`/`, `/system`, `/disks`, `/llm`, `/ups`, `/settings`, `/certs`) — a `GET` (signed, like the other served-page pins) finds `button#nav-toggle` with `aria-expanded="false"`, `aria-controls="nav-tabs"`, `aria-label="Toggle navigation"`, and `type="button"`, and `nav#nav-tabs` with its five tab links intact; the button precedes the nav in the markup (the dropdown's `top: 100%` anchor needs the nav inside the masthead, which the pin asserts via the `header.masthead` containing both).
+   - `test_the_login_page_carries_no_nav_and_no_toggle`: `/login` (fetched the way the audit fetches it — unsigned, because a signed-in `GET /login` is a `303`) has no `nav.tabs`, no `#nav-toggle`, and no `#nav-tabs` — the page's contract is brand + theme toggle only, and a stray hamburger there is the bug this test exists to fail.
+   - `test_the_nav_toggle_css_and_binding_carry_the_same_breakpoint`: the served `dash.css` contains the base `.nav-toggle` `display: none` rule, a `@media (max-width: 640px)` (or the 640px block) with the toggle-visible, `nav.tabs`-hidden, and `.is-open` rules; the served `app.js` contains the binding block (the `is-open` toggle, the `Escape` close, the `matchMedia('(max-width: 640px)')` call) — and the `640px` literal appears in both, so a drift between CSS and JS fails here instead of opening a menu into a `display:none` nav.
+2. `tests/test_auth_api.py` — **no change expected**: the served-page orphan-`id` audit (line 1654) must pass untouched, because `#nav-toggle` and `#nav-tabs` are referenced (the stylesheet rule, `aria-controls`, the `app.js` selectors). If the audit flags either id, the fix is in the CSS/JS references, not in the audit.
+3. Browser verification (invariant 10): `./scripts/dev-server.sh restart`, sign in with `testpass`, and with a ≤640px viewport (Playwright or a devtools device width — the repo's screenshots land in `data/logs/`):
+   - `data/logs/nav-hamburger-closed-360.png` — the phone-width masthead: no tab links, the `☰` visible, the `masthead-right` cluster intact.
+   - `data/logs/nav-hamburger-open-360.png` — the dropdown open: five stacked links, the `aria-current` tab highlighted, the cluster not covered.
+   - `data/logs/nav-masthead-desktop-1280.png` — the no-regression shot: one-row masthead, inline tabs, no button.
+4. `AGENTS.md` — in the `UI conventions` section (where the `/login` masthead contract and the `app.js` ownership are documented), add the collapsing contract in the section's voice: the 640px breakpoint, the toggle's identity and its seven-page scope, the three close paths (link click, Esc with focus return, resize-back), the `aria-expanded` rule, and that `/login` carries no toggle. `README.md` is checked in the phase's final pass (its page table — "power events" etc. — is unchanged by this phase).

+## Testing & Quality

+# Phase 19 — Expandable UPS power-events list

+**Story:** n/a
+**Context:** `src/dashboards/web/pages/ups.html` lines 72–76 (the `Power events` card: `<header><h3>` + a `ul.events#events` holding a `loading…` placeholder), `src/dashboards/web/static/page-ups.js` (`refreshEvents()` at line 430 — fetches `/api/events?limit=200&source=ups` and hands the rows to `Dash.eventsPager` with the date/time + severity-chip + host row shape; called unconditionally from `refresh()` at line 427, which the page's `poll(refresh, state.pollMs)` loop drives, `state.pollMs` from `config.ups.poll_ms || 5000`), `src/dashboards/web/static/app.js` (`Dash.eventsPager` — 50 rows a page, paging state in a `WeakMap` keyed by the `<ul>`, rows re-written only when their markup changed), `src/dashboards/web/static/dash.css` (`details.charts-box` at lines 714–727 — the summary marker `▸`/`▾`, hidden webkit marker, hover; the `.events` bounded 320px scroll and `.events-pager` strip), and the pattern this phase mirrors — `/system`'s per-host Charts disclosure (`system.html` line 81, `page-system.js` line 315: "a `<details>` renders nothing, so … nothing is built or drawn while the stack is shut") and its pin `test_system_history_charts_are_collapsed_behind_a_toggle`
+
+## Objective
+
+The `/ups` power-events list becomes what the TODO asks for — *expandable*: the card is collapsed by default behind a `<details>` disclosure in the repo's own `charts-box` style, nothing is fetched or drawn while it is shut (the `/system` rule), the first expand fetches and builds, a re-expand paints from the data in hand unless it is stale, and the page's poll loop refreshes the list only while the disclosure is open. The "clear" half already ships and stays: every row carries its date/time, the severity chip, and the host, and the 50-per-page pager bounds the list. No new API surface — the existing `/api/events?source=ups` is the whole backend.
+
+## Dependencies
+- `18_nav_hamburger` (todo) — both phases touch `ups.html` (the masthead, the events card); landing 18 first keeps this phase's diff confined to the events section. No shared code between them.
+
+## Tasks
+1. `01_events_disclosure.md` — the `ups.html` markup: the card body becomes a collapsed-by-default `<details class="events-box">`
+2. `02_events_lazy_loading.md` — `page-ups.js`: no fetch while closed, first-expand fetch, re-expand stale rule, poll-while-open
+3. `03_disclosure_css.md` — `dash.css`: the `details.events-box` summary styling in the `charts-box` shape, pager and bounded list inside
+4. `04_tests_and_verification.md` — the served-page pins (disclosure present and unopened, the lazy rule, the unchanged row shape) and the closed/open browser verification
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the served-page pins (see task 04), alongside the untouched `Dash.eventsPager` behaviour (a re-paint with the same data keeps the reader's page — the `WeakMap` rule, pinned by the existing event-feed tests)
+- Coverage: **>90%** on new/modified code (the phase is markup + JS + CSS; the gate applies to the changed Python test files)
+- The phase is "Complete" only when the **entire** project test suite passes 100% (every test in the project, not just this phase's)
+
+## Documentation & Consistency
+

+# Task 01 — The disclosure markup
+
+**Phase:** `19_ups_events_expandable` · **Source:** `TODO.md:4` — "The UPS tab should have an expandable, clear list of last incidents with dates/times"
+**Story:** n/a
+
+## Objective
+
+The `Power events` card on `/ups` becomes a collapsed-by-default `<details>` disclosure, in the markup shape the repo already owns for `/system`'s Charts stack. The card stays a card; only its body moves inside the disclosure. The `loading…` placeholder stays in the `ul` — it is the honest state between the first expand and the first successful fetch (the pager's output replaces it on arrival; an empty feed then prints the pager's own `empty` sentence, which is a different fact).
+
+## Work
+
+1. `src/dashboards/web/pages/ups.html` — restructure the section at lines 72–76 from
+   ```html
+   <section class="card" style="margin-top:.85rem">
+     <header><h3>Power events</h3></header>
+     <div class="body"><ul class="events" id="events"><li class="muted">loading…</li></ul></div>
+   </section>
+   ```
+   to
+   ```html
+   <section class="card" style="margin-top:.85rem">
+     <details class="events-box">
+       <summary>Power events</summary>
+       <div class="body"><ul class="events" id="events"><li class="muted">loading…</li></ul></div>
+     </details>
+   </section>
+   ```
+   — no `open` attribute (collapsed by default; `ASSUMPTION:` confirmed by the operator — "expandable" means the list is shut until the operator opens it, the `/system` Charts pattern). The `#events` id, the `ul.events` class (the bounded 320px scroll + `.events-pager` strip target it), the `loading…` placeholder, and the pager's contract are all the page-script's, so nothing else in the file moves.
+2. `ASSUMPTION:` the summary is the plain word `Power events` (the old `<h3>` text) — no count chip on the summary. A count that has not been fetched would be an invented number (rule 2), and the pager under the list already says `1–50 of N` once data is in hand.
+3. `ASSUMPTION:` the disclosure is a plain `details` (no `data-k` attribute) — `/system`'s `data-k="charts"` exists for the per-host JS that rebuilds the stack; here the single page-level `page-ups.js` queries it by class, and the pin in task 04 names the class, not an attribute.
+
+## Testing & Quality
+- Integration: the served-page pin lands in task 04 (`details.events-box` present on the served `/ups`, no `open` attribute, the `summary` label, the `#events` ul inside, no `loading…` placeholder); the untouched page renders (the browser verification is task 04)
+- Coverage: **>90%** on modified code (HTML only; the gate's suite must stay green)

+# Task 02 — The lazy loading in `page-ups.js`
+
+**Phase:** `19_ups_events_expandable` · **Source:** `TODO.md:4` — "The UPS tab should have an expandable, clear list of last incidents with dates/times"
+**Story:** n/a
+
+## Objective
+
+Nothing is fetched or drawn while the disclosure is shut (the `/system` rule: "nothing is built or drawn while the stack is shut"), the first expand fetches and builds, a re-expand paints from the data in hand unless it is stale, and the page's poll loop refreshes the list only while the disclosure is open. The row shape, the pager, and the `loading…`-then-rows sequence are unchanged.
+
+## Work
+
+1. `src/dashboards/web/static/page-ups.js` — `state` (line 17) gains one key, in the object's existing style: `events: { open: false, painted: false, fetchedAt: 0 }`.
+2. Same file, the `refresh()` function (the `await refreshEvents();` at line 427 is its last statement) — the unconditional call becomes the open-gate:
+   ```js
+   if (state.events.open) await refreshEvents();
+   ```
+   — the poll loop (the `state.poller = poll(refresh, state.pollMs)` at line 464) keeps driving the list **only while the disclosure is open**; closed, the page pays nothing for a feed nobody can see.
+3. Same file, `refreshEvents()` (line 430) — on success, before/after the existing `Dash.eventsPager(…)` call, stamp the state: `state.events.fetchedAt = Date.now(); state.events.painted = true;`. The existing `catch (err) { /* next poll */ }` stays untouched — a failed fetch leaves `painted`/`fetchedAt` where they were, so the next open re-fetches, and a failed poll while open keeps the last good rows (the invariant-4 shape, already the page's behaviour for everything else).
+4. Same file, inside the `DOMContentLoaded` handler, before `state.poller = poll(…)`:
+   ```js
+   const eventsBox = $('.events-box');
+   if (eventsBox) {
+     state.events.open = eventsBox.open; // false — task 01 ships no `open` attribute
+     eventsBox.addEventListener('toggle', () => {
+       state.events.open = eventsBox.open;
+       if (!eventsBox.open) return;
+       // First expand: `painted` is false — fetch. Re-expand: paint from the data
+       // in hand only while it is fresh; a cache older than one poll interval is
+       // stale and re-fetches. A fresh, already-painted list needs nothing: the
+       // `<details>` keeps its children, so the rows (and the pager's page, in its
+       // WeakMap) are already where the operator left them.
+       if (!state.events.painted || Date.now() - state.events.fetchedAt > state.pollMs) {
+         refreshEvents();
+       }
+     });
+   }
+   ```
+   `ASSUMPTION:` the stale bound is **one poll interval** (`state.pollMs`, from `config.ups.poll_ms || 5000`) — the `/system` Charts rule re-fetches a cached response "from another window"; here the window is the page's own, so one interval is the honest bound. A re-open within the interval paints the cache; a re-open after it re-fetches.
+5. `ASSUMPTION:` no `loading…` fiddling — the placeholder from task 01 stays in the `ul` until the first successful fetch's pager output replaces it (a `<details>` does not destroy its children, so the placeholder, the rows, and the pager strip all survive collapse/re-expand untouched).
+
+## Testing & Quality
+- Integration: the served-script pins land in task 04 (the `state.events` shape, the `refresh()` open-gate, the `toggle` listener with its stale rule — asserted on the served bytes, the repo's way for JS behaviour since it has no JS test runner); `node --check` of the modified file passes (the gate); the untouched `Dash.eventsPager` tests stay green
+- Coverage: **>90%** on modified code (JS; the gate's Python checks apply to task 04's test files)

+# Task 03 — The disclosure CSS
+
+**Phase:** `19_ups_events_expandable` · **Source:** `TODO.md:4` — "The UPS tab should have an expandable, clear list of last incidents with dates/times"
+**Story:** n/a
+
+## Objective
+
+The `details.events-box` summary renders in the shape the repo already owns for `/system`'s Charts disclosure (`details.charts-box`, `dash.css` lines 714–727): the `▸`/`▾` marker, the hidden webkit marker, the hover, and the open-state de-emphasis — so a second opinion about the drive's word is never the bug, and a page that ships the summary without the style is the drift this task's pin catches.
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — beside the existing `details.charts-box` rules (lines 714–727), add the `events-box` rules in the same block's voice (one selector per property, the file's style):
+   ```css
+   details.events-box { min-width: 0; }
+   details.events-box > summary {
+     cursor: pointer; list-style: none;
+     font-weight: 600; color: var(--text-muted);
+     padding: .4rem .8rem .4rem 1.4rem;
+     position: relative;
+   }
+   details.events-box > summary::-webkit-details-marker { display: none; }
+   details.events-box > summary::before {
+     content: "\25B8"; position: absolute; left: .6rem;
+     font-size: 9px; color: var(--text-faint);
+   }
+   details.events-box[open] > summary::before { content: "\25BE"; }
+   details.events-box > summary:hover { color: var(--text-muted); }
+   details.events-box[open] > summary { color: var(--text-muted); margin-bottom: .55rem; }
+   ```
+   (match the `charts-box` block's actual property set line-for-line — the snippet is the shape, the neighbouring block is the ground truth; do not invent tokens `:root` does not declare — the file's rule, pinned by `tests/test_api.py`).
+2. The card's existing `.body` wrapper (task 01's markup) carries the `ul.events` bounded scroll (the existing 320px rule) and the `.events-pager` strip — **no new rules** for those; verify they resolve inside the disclosure (the `.body` is a child of `details`, and the existing selectors are class-based, so they do — confirm in the browser, task 04).
+3. `ASSUMPTION:` no open/close animation on the disclosure — `charts-box` has none, and the file's `prefers-reduced-motion` block exists for the things that do move; a summary that snaps is the house style.
+
+## Testing & Quality
+- Integration: the served-stylesheet pin lands in task 04 (the `details.events-box` rule family present, the `::before` markers, no token a `:root` does not declare — the existing `test` that fails if a CSS rule reaches for an undeclared token must pass untouched); the `node --check` gate is unaffected (CSS), and the page loads in the browser (task 04)

+# Task 04 — Pins and browser verification
+
+**Phase:** `19_ups_events_expandable` · **Source:** `TODO.md:4` — "The UPS tab should have an expandable, clear list of last incidents with dates/times"
+**Story:** n/a
+
+## Objective
+
+The phase is pinned on the served bytes the way this repo pins every page surface: the disclosure is on the served `/ups` and **unopened**, the lazy-load rule is in the served script, and the row shape — the "clear" half of the TODO (date/time, severity chip, host) — is unchanged. Then the designed degradation is proven in a real browser: the closed state, the open state, and the no-request-while-closed fact.
+
+## Work
+
+1. `tests/test_api.py` — new tests, in the file's served-page style (the `self_test_app` harness and the `test_system_history_charts_are_collapsed_behind_a_toggle` pin at the `/system` disclosure are the models):
+   - `test_the_ups_power_events_list_is_a_collapsed_disclosure`: a signed `GET /ups` finds `details.events-box` with **no** `open` attribute, a `summary` reading `Power events`, and the `ul.events#events` (with its `loading…` placeholder) inside it — and the old always-open shape is gone (no bare `header > h3` directly above the `ul` at the section level).
+   - `test_the_ups_events_fetch_is_gated_on_the_disclosure`: the served `page-ups.js` carries the lazy rule — the `state.events` shape (`open`, `painted`, `fetchedAt`), the `refresh()` open-gate (`state.events.open` guard on the `refreshEvents()` call), and the `toggle` listener with the stale bound (`state.pollMs`) — asserted on the served script text, the repo's established device for JS behaviour (no JS test runner; the `node --check` in the gate covers syntax).
+   - `test_the_ups_event_rows_keep_the_date_time_and_severity_shape`: the served `page-ups.js` row template still renders the `<time>` with the date/time `toLocaleString` options, the `sev ${event.severity}` chip, and the host — the "clear list with dates/times" the TODO asks for, pinned so a "cleanup" that drops the timestamp fails here instead of shipping.
+2. The existing event-feed pins (`tests/test_api.py`'s `Dash.eventsPager`-behaviour tests, the `EVENT_FEED_LIMIT`/`EVENT_PAGE_SIZE` pairing) pass **untouched** — the phase adds no API surface and no pagination vocabulary.
+3. Browser verification (invariant 10): `./scripts/dev-server.sh restart`, sign in with `testpass`, real upsd in the loop (the dev config dials the fleet's `upsd` on 3051 — two real UPSes, no `NUT_SIMULATE`):
+   - `data/logs/ups-events-closed.png` — the page with the card collapsed: the `Power events` summary line, no list, and the devtools network panel showing **no** `/api/events?source=ups` request on the first poll (screenshot the panel or note the request count in the filename's companion note).
+   - `data/logs/ups-events-open.png` — the expanded card: the bounded scroll list with date/time rows, the severity chips, and the `1–50 of N` pager strip (or the empty sentence, if the event table is genuinely empty — either is the correct state; the pin is the *shape*, not the data).
+4. `AGENTS.md` — in the `UI conventions` section, beside the event-pager paragraph ("An event feed is a window, not a printout") and the `/system` Charts-disclosure paragraph, add the `/ups` sentence in the section's voice: the list is a collapsed-by-default `details` disclosure, nothing is fetched while it is shut, the first expand fetches and builds, a re-expand paints the cache while it is fresher than one poll interval (stale re-fetches), and the poll loop refreshes only while open. `README.md` is checked in the phase's final pass (its `/ups` row — "power events" — stays true; the list is on the page, behind a summary).

+# Phase 20 — Masthead & navigation polish
+
+**Source:** `TODO.md` L4, L5, L6, L10, L11 — "masthead row layout, un-sticky bar, hamburger animation, always-visible admin links"
+**Story:** n/a
+**Context:** `src/dashboards/web/static/dash.css` (`.masthead` at line 99 — `position: sticky; top: 0; z-index: 40; display: flex; height: var(--header-h)`; `.masthead-right` at line 148 — `margin-inline-start: auto`; `#nav-toggle` at line 190 — the `--nav-toggle-display` token reveal; the ≤640px block at lines 208–280 — masthead wrap, `masthead-right { justify-content: flex-end }`, the `nav.tabs` dropdown at `top: 100%` under the sticky bar, the `env(safe-area-inset-top, 0px)` padding line), `src/dashboards/web/static/app.js` (the `setNavMenu()` funnel at lines 695–722 — four close paths, `matchMedia('(max-width: 640px)')`), `src/dashboards/web/pages/*.html` (the masthead in every page: brand, `#nav-toggle`, `nav.tabs#nav-tabs`, `.masthead-right` holding `#nav-status` + clock + `⚷ Certs` + `⚙ Account` + theme toggle; `certs.html` lacks `⚷ Certs`, `settings.html` lacks `⚙ Account` — the phase-15 "no self-link" rule this phase inverts), `tests/test_api.py` (`test_every_page_links_to_both_admin_pages` at line 999, `test_the_disks_tab_is_in_the_masthead_of_every_page` at line 3913, `test_the_nav_toggle_is_in_the_masthead_of_every_tabbed_page` at line 3957)
+
+## Objective
+
+The masthead becomes a three-row bar at **all widths** — row 1 the brand and the five dashboard tabs, row 2 the per-source status indicators left-justified in their own row, row 3 the `⚷ Certs` / `⚙ Account` / `☾ Dark` controls left-justified in their own row under the indicators — the bar stops being sticky (it scrolls away, maximising data screen space), the hamburger menu slides out and back in (180 ms, the `brain_of_reese` pattern, stilled under `prefers-reduced-motion`), and both admin links stay visible on every page including the two admin pages themselves. The served page markup is unchanged except the two added admin links; the tab structure (five links, one `aria-current`), the `#nav-toggle` token reveal, the safe-area padding line and the four close paths all stay exactly as phase 18 pinned them.
+
+## Dependencies
+- `19_ups_events_expandable` (todo) — both phases touch `ups.html` (the masthead, the events card); landing 19 first keeps this phase's diff confined to the masthead.
+
+## Tasks
+1. `01_two_row_masthead.md` — the three-row left-justified masthead at all widths (CSS-only reflow; the mobile block re-cut for the new rows)
+2. `02_unsticky_masthead.md` — the bar scrolls away: `sticky` → `relative`, the dropdown anchor kept
+3. `03_hamburger_slide.md` — the 180 ms slide+fade on the ≤640px dropdown, stilled under `prefers-reduced-motion`
+4. `04_admin_links_visible.md` — `⚷ Certs` on `/certs`, `⚙ Account` on `/settings`; the "no self-link" pin inverted to "all eight pages link to both"
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the served-page pins (task 04's rewritten admin-link test over all eight non-login pages, the unchanged tab-structure pins at lines 3913/3957, the CSS pins for the row layout and the un-sticky change), the unchanged `setNavMenu` behaviour
+- Coverage: **>90%** on new/modified code (the phase is markup + JS + CSS; the gate applies to the changed Python test files)
+- The phase is "Complete" only when the **entire** project test suite passes 100% (every test in the project, not just this phase's)
+
+## Documentation & Consistency
+
+- The final pass reviews `README.md` and `AGENTS.md` in full against the project as it stands after this phase — fixing every inconsistency found, **including pre-existing ones not caused by this phase**. AGENTS.md's masthead paragraph (the phase-18 "specificity ladder" and the `top: 100%`-under-the-sticky-bar wording) and the phase-15 "neither admin page links to itself" sentence (gap 12's "now questioned" item — this phase is the decision) both get rewritten to the new state in the section's voice.
+
+## Completion Criteria
+- [ ] at 1280 px and at 360 px, every tabbed page and both admin pages render the three-row masthead: brand + tabs, left-justified indicators row, left-justified controls row under it (screenshots in `data/logs/`, invariant 10)

+# Task 01 — The three-row left-justified masthead, at all widths
+
+**Phase:** `20_masthead_nav_polish` · **Source:** `TODO.md:5,6` — "The hosts disks engines and UPS indicators should be left justified in their own row" / "The ⚷ Certs ⚙ Account ☾ Dark buttons should be left justified in their own row under the hosts disks engines UPS indicators"
+**Story:** n/a
+
+## Objective
+
+The single-row masthead becomes a three-row bar at **every** width: row 1 keeps the brand, `#nav-toggle` and the five dashboard tabs; row 2 is the `#nav-status` indicator row (the per-source dots), left-justified and on its own; row 3 is the `.masthead-right` cluster (clock, `⚷ Certs`, `⚙ Account`, `☾ Dark` — plus the `⏸ Pause` button until phase 21 removes it), left-justified and on its own row under the indicators. The change is CSS-only: no page markup changes in this task, so the served-HTML pins (tab structure, toggle placement) stay green untouched.
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — `.masthead` (line 99): `display: flex; flex-direction: column; align-items: stretch; gap: .35rem` (replacing the row layout's `align-items: center; gap: 1.1rem`), `height: var(--header-h)` replaced by `min-height: var(--header-h)` (the ≤640px block already carries its own `min-height` — keep the mobile one, the two must not drift apart; see the comment it carries), `position: sticky; top: 0` **left in place in this task** (task 02 removes the stickiness; keep `z-index: 40`), and a positioned wrapper for row 1: the first flex child is the existing `brand` + `#nav-toggle` + `nav.tabs` trio — since the markup is not touched, use CSS `order`/`flex` only: `#nav-status` and `.masthead-right` each get `flex-basis: 100%` (forcing the row break), `nav.tabs` keeps its current inline position on row 1 (it already flows after the toggle). If `flex-basis: 100%` does not force a row break on the `nav` element in the pinned browser, the fallback is a `display: contents` wrapper-free `flex-wrap: wrap` on `.masthead` with the same `flex-basis: 100%` rules — measure in a browser, do not deduce (the phase-18 rule).
+2. `src/dashboards/web/static/dash.css` — `#nav-status` (the `gap` container, line 148 neighbourhood): its own row styling — `flex-basis: 100%; display: flex; align-items: center; gap: .55rem; justify-content: flex-start` (left-justified, no `margin-inline-start: auto`).
+3. `src/dashboards/web/static/dash.css` — `.masthead-right` (line 148): `margin-inline-start: auto` removed, `flex-basis: 100%; justify-content: flex-start` (left-justified, the TODO's words). The `⏸ Pause` button stays in this row (phase 21 deletes it; do not pre-empt it).
+4. `src/dashboards/web/static/dash.css` — the ≤640px block (lines 208–280): re-cut for the new rows — the whole-bar `flex-wrap`/`min-height` machinery of the old wrap is replaced by the mobile half of the same three-row layout: `#nav-toggle` keeps its `--nav-toggle-display: inline-flex` reveal on row 1 (the token ladder stays exactly as pinned), `nav.tabs` stays hidden except `nav.tabs.is-open` (the dropdown), the `masthead-right > *` no-wrap rule and the `env(safe-area-inset-top, 0px)` top padding line (pinned by `tests/test_api.py`'s rule loop) survive verbatim, and the comment at line 203 (which describes the old 360 px wrap) is rewritten to the new three-row reality. The dropdown's `top: 100%` now lands under the **whole bar** (three rows) on mobile — that is the intended look (a menu under the bar, not wedged between rows); verify in a browser at 360 px.
+5. `tests/test_api.py` — extend the served-stylesheet pins for the new layout: `.masthead` has `flex-direction: column` (or the `flex-wrap` fallback, whichever shipped) and no fixed `height: var(--header-h)`, `#nav-status` and `.masthead-right` are both `flex-basis: 100%` + `justify-content: flex-start`, and `.masthead-right` no longer declares `margin-inline-start: auto`. The existing pins (the media-query-vs-`matchMedia` comparison, the safe-area line, the token ladder) must stay green — run them before touching the file.

+# Task 02 — The masthead is not sticky
+
+**Phase:** `20_masthead_nav_polish` · **Source:** `TODO.md:10` — "The navbar is only sticky part way down certain pages on mobile? It shouldn't be sticky at all. We want to maximize the amount of screen space for data viewing."
+**Story:** n/a
+
+## Objective
+
+The masthead scrolls away with the page. The "sticky part way down" quirk is the fixed-height sticky bar fighting the wrapped rows on mobile; removing the stickiness removes the quirk and the bar's vertical footprint. The ≤640px dropdown (`nav.tabs.is-open` at `top: 100%`) still opens directly under the bar, because the bar stays a **positioned** ancestor — `position: relative` keeps the anchor without the stick.
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — `.masthead` (line 99): `position: sticky; top: 0` → `position: relative` (keeps the positioned-ancestor role for the dropdown's `top: 100%` and the `left/right: 0` span; `z-index: 40` stays — the dropdown's `z-index: 41` is "one above the masthead" and that sentence stays true).
+2. `src/dashboards/web/static/dash.css` — the dropdown comment (line 266: "`position: sticky`, which is a positioned ancestor") rewritten to `position: relative`; any other comment in the file that calls the bar sticky gets the same fix.
+3. `tests/test_api.py` — any pin that asserts the `position: sticky` declaration (grep the test files for `sticky`) is updated to assert `position: relative` **and** the absence of `top: 0` on `.masthead`; if no pin named the declaration, add one to the layout pin loop from task 01 so the stickiness cannot quietly return.
+4. `src/dashboards/web/static/dash.css` — check the `sticky; top: 0` at line 796 (a **different** element — the event-feed pager strip's own sticky header): it is not the masthead, do not touch it.

+# Task 03 — The hamburger menu slides out and back in
+
+**Phase:** `20_masthead_nav_polish` · **Source:** `TODO.md:11` — "I want a nice animation for the hamburger menu - a slide out and slide back in would be perfect. See ~/Project/Personal/brain-of-reese for an example."
+**Story:** n/a
+
+## Objective
+
+The ≤640px dropdown (`nav.tabs.is-open`) opens and closes with an 180 ms slide+fade instead of snapping — the exact pattern the operator pointed at in `brain_of_reese`: closed = `visibility: hidden; opacity: 0; transform: translateY(-8px); pointer-events: none` with a `visibility 0s linear 180ms` delayed transition, open = `visibility: visible; opacity: 1; transform: none; pointer-events: auto` with the `visibility` delay dropped, and the whole thing stilled under `prefers-reduced-motion` with **both states named** (the reference project's phase-46 comment: an open-state transition that is not stilled still animates). `app.js`'s `setNavMenu()` funnel and its four close paths are untouched — the animation is pure CSS over the existing class flip.
+
+## Work
+
+1. Reference (read-only): `/var/home/ducoterra/Projects/Personal/brain_of_reese/frontend/assets/styles.css` lines 6960–6976 (the `.app-nav` closed/open transition pair — note the TODO's path `~/Project/Personal/brain-of-reese` is a typo; the project lives at `~/Projects/Personal/brain_of_reese`) and lines 7228–7235 (the `prefers-reduced-motion` block that names **both** `.app-nav` and `.app-nav.is-open`, with the specificity comment: an open rule that is not named keeps animating).
+2. `src/dashboards/web/static/dash.css` — inside the ≤640px block (lines 208–280), the `nav.tabs` rule (the dropdown): add the closed-state properties + transition from the reference (adapted: this nav is `position: absolute; top: 100%`, so the slide is `transform: translateY(-8px)` → `none`, same 180 ms ease; keep the existing `visibility: hidden`/`pointer-events: none` closed-state behaviour if it is already there, otherwise add it — measure the current rule first, do not assume). The `nav.tabs.is-open` state gets the visible counterpart with the `visibility 0s` (undelayed) transition.
+3. `src/dashboards/web/static/dash.css` — a `@media (prefers-reduced-motion: reduce)` block (the file's first, or merged with an existing one if there is one) that sets `transition: none` on **both** `nav.tabs` and `nav.tabs.is-open` — both states named, per the reference's phase-46 comment.
+4. `tests/test_api.py` — extend the served-CSS pin for the mobile block: the `nav.tabs` rule carries an `opacity`/`transform` transition of 180 ms, the `is-open` state carries the visible counterpart, and the reduced-motion block names both states. The existing media-query-vs-`matchMedia` comparison test stays green untouched (the transition is additive; the `640px` literal still lives in exactly the two pinned places).

+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the pins above; the unchanged four-close-path behaviour (the `setNavMenu` funnel tests)
+- Coverage: **>90%** on this task's new/modified code
+- Browser verification (invariant 10): at 360 px, open and close the menu — a CDP check that the computed `transition` runs (a mid-transition screenshot is not required; assert the closed state's `opacity: 0` + `transform: translateY(-8px)` computed values and that a frame after `.is-open` is added shows `opacity > 0`), and with `prefers-reduced-motion: reduce` emulated the menu snaps (computed `transition: none`) — extend the phase-18 verification script pattern (`data/logs/nav-task04-verify.cjs`) rather than hand-asserting

+# Task 04 — Both admin links stay visible on the admin pages
+
+**Phase:** `20_masthead_nav_polish` · **Source:** `TODO.md:4` — "Clicking the certs tab causes the certs button to disappear, then clicking the account tab causes the accounts button to disappear. These should remain visible."
+**Story:** n/a
+
+## Objective
+
+Phase 15's deliberate "neither admin page links to itself" rule is inverted by operator decision (it was already "now questioned" in AGENTS.md gap 12): `certs.html` gains the `⚷ Certs` link and `settings.html` gains the `⚙ Account` link, so the masthead's controls are identical on all eight non-login pages. The links sit before the theme toggle and outside `.tabs` exactly as on the five dashboards; the tab structure (five links, no `aria-current` on the admin pages) and the `/login` page (brand + theme toggle only) are untouched.
+
+## Work
+
+1. `src/dashboards/web/pages/certs.html` — the masthead (lines 14–28): insert `<a class="ghost account" href="/certs" title="Agent certificates">⚷ Certs</a>` between the clock and the `⚙ Account` link (the dashboard order is clock → `⚷ Certs` → `⚙ Account` → theme toggle; `settings.html` already holds that order), and rewrite the HTML comment at lines 14–17, which currently justifies the *missing* link, to the new rule (both links everywhere; a self-link is a no-op the operator can click and not be surprised by — the TODO is the decision).
+2. `src/dashboards/web/pages/settings.html` — the masthead (lines 14–30): insert `<a class="ghost account" href="/settings" title="Session and password">⚙ Account</a>` between the `⚷ Certs` link and the theme toggle; the comment at lines 12–14 ("It is reached from the `⚙ Account` link in the masthead of every dashboard") gains the "including this one" sentence.
+3. `tests/test_api.py` — rewrite `test_every_page_links_to_both_admin_pages` (line 999): the two loops become **one** loop over all eight non-login pages (`*PAGES, SETTINGS_PAGE, CERTS_PAGE`) asserting both links are present, both before `id="theme-toggle"`, and `"/certs"` is not in the `.tabs` markup; the two `assert … not in … "links to itself"` lines are **deleted** (that was the old rule); add one explicit assertion that `login.html` carries **neither** link (the pre-auth surface renders brand + theme toggle only — that sentence in AGENTS.md stays true).
+4. `AGENTS.md` — (Documentation & Consistency pass) the phase-15 "neither admin page links to itself, which is why the pinned two-link audit loops over two different tuples" sentence and gap 12's "now questioned" item are resolved to the new state.

+# Phase 21 — Page cleanups: pause, GPU values, certs scroll
+
+**Source:** `TODO.md` L7, L9, L12 — "remove the pause button, GPU data as its own values, /certs table horizontal scroll"
+**Story:** n/a
+**Context:** `src/dashboards/web/pages/{disks,llm,system,ups}.html` line 25 (the `#pause` button, the only one in the served markup — `/`, `/certs` and `/settings` have none), `src/dashboards/web/static/app.js` (lines 587–615 the `poll()` `_paused` plumbing, lines 773–783 the `#pause` binding plus the `Space` shortcut), `src/dashboards/web/static/dash.css` line 203 (the comment naming the pause button), `src/dashboards/web/static/page-system.js` (lines 150–156 `gpuSub()` — the dense sub-line the TODO quotes, lines 164–188 `renderGpuSlot()`, line 72 the `data-k="gpus"` hero slot), `tests/test_api.py` (line 1425 — the six-heroes pin: "exactly six heroes: CPU, MEM, TEMP, DISK, GPU, NET", asserted over the three captures: discrete GPU, APU, no-GPU), `src/dashboards/web/pages/certs.html` line 81 (`<table class="data" id="agents-table">` — no `.scroll` modifier; `dash.css` gives `table.data` a scroll container only with the `.scroll` class), `src/dashboards/web/static/page-certs.js` (lines 55–56 — the table element references)
+
+## Objective
+
+Three small page-level cleanups, one per workstream: the pause button is gone from every page (the hidden-tab skip stays — a background tab idling its polls is not the operator's pause), the `/system` GPU data is split out of the dense sub-line into its own labelled values and a host with no GPU **omits** the slot instead of printing `n/a`, and the `/certs` agents table scrolls horizontally so the right-hand columns are reachable on a phone. No API surface changes; the pins that name the old behaviour (six heroes incl. an `n/a` GPU slot, the unpinned pause button) are rewritten, not left rotting.
+
+## Dependencies
+- `20_masthead_nav_polish` (todo) — the pause button lives in the masthead row task 01.01 reflows, and the `/system` hero row is re-measured under the new bar; landing 20 first keeps 21's diff confined to the page bodies.
+
+## Tasks
+1. `01_remove_pause_button.md` — delete the button, the `Space` shortcut, the `setPaused`/`_paused` plumbing and the CSS comment; the hidden-tab skip survives
+2. `02_gpu_own_values.md` — the dense `gpuSub()` line becomes four labelled values per card; a GPU-less host omits the slot (five heroes, no `n/a`)
+3. `03_certs_table_scroll.md` — `#agents-table` gets the `.scroll` modifier so its right-hand columns are reachable at phone width
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the served-page pins: the pause button absent from the four pages (a return of `#pause` fails a test), the six-heroes pin rewritten (GPU-present host: six, GPU-absent host: five with no `data-k="gpus"` slot), the `#agents-table` `.scroll` pin; `tests/test_system_contract.py` + `tests/card_contract.py` stay green (the API fields are unchanged — only the page's reading of them moves)
+- Coverage: **>90%** on new/modified code (the phase is markup + JS + CSS; the gate applies to the changed Python test files)
+- The phase is "Complete" only when the **entire** project test suite passes 100% (every test in the project, not just this phase's)
+
+## Documentation & Consistency
+
+- The final pass reviews `README.md` and `AGENTS.md` in full against the project as it stands after this phase — fixing every inconsistency found, **including pre-existing ones not caused by this phase**. AGENTS.md's `/system` paragraph ("a missing number or verdict — gateway's CPU temp, any host's absent GPU — prints `n/a` **uncoloured**") is the one rule this phase inverts for the GPU slot (the CPU-temp `n/a` stays — the TODO quotes the GPU line only); the sentence is split, the GPU half rewritten to the omission rule, and the pause button's mention in the masthead comment dropped.
+
+## Completion Criteria
+- [ ] no page serves a `#pause` button or binds the `Space` key; a hidden tab still skips its polls (served-bytes pin + a CDP `visibilitychange` check)
+- [ ] `/system`'s GPU slot prints model / VRAM / pool / temp as four labelled values; a GPU-less host (the no-GPU capture, gateway) renders five heroes with no GPU slot and no `n/a` in it (screenshots in `data/logs/`)

+# Task 01 — Remove the pause button
+
+**Phase:** `21_page_cleanups` · **Source:** `TODO.md:7` — "Completely remove the pause button"
+**Story:** n/a
+
+## Objective
+
+The `⏸ Pause` control is gone from the served markup, the page scripts and the shared poller: no button, no `Space`-key shortcut, no `setPaused`/`_paused` plumbing. The **hidden-tab** behaviour survives — `document.hidden` still skips a poll while the tab is backgrounded and `visibilitychange` still fires one on return; that is idle hygiene, not the operator's pause, and the TODO names the button only.
+
+## Work
+
+1. `src/dashboards/web/pages/disks.html`, `src/dashboards/web/pages/llm.html`, `src/dashboards/web/pages/system.html`, `src/dashboards/web/pages/ups.html` — delete the line-25 `<button class="ghost" id="pause" type="button" aria-pressed="false">⏸ Pause</button>` from each of the four (the only served occurrences — `/`, `/certs`, `/settings`, `/login` have none; a grep of `web/pages` for `pause` must come back empty when done).
+2. `src/dashboards/web/static/app.js` — delete the `#pause` binding block (lines 773–783: the button lookup, the `aria-pressed` paint, the click handler, and the `keydown` `Space` handler with its `event.preventDefault()`); in `poll()` (lines 587–615) delete the `_paused` state, `setPaused()`, the `paused` getter and the `state._paused` checks in `tick()`/`schedule()`/`visibilitychange` — the `document.hidden` guard and the `visibilitychange` refire stay, minus the `&& !state._paused` clause; the docstring at line 587 ("pausing when the tab is hidden or the user hit pause") drops the pause half.
+3. `src/dashboards/web/static/dash.css` — line 203's comment (which lists "status dots, pause, `⚷ Certs`, `⚙ Account`, theme" as the 360 px wrap's tenants) drops the pause mention.
+4. `tests/test_api.py` — add the served-bytes pin: `id="pause"` is **absent** from all eight served pages (a return of the button fails a test) and `⏸` appears nowhere in the served scripts.
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the absence pin above; the existing poller tests (the `Dash.poll` hidden-tab behaviour, if any pin it — grep `hidden` in the test files first) stay green
+- Coverage: **>90%** on this task's new/modified code
+- Browser verification (invariant 10): `/` and `/system` — no pause control in the masthead, the `Space` key does nothing on the page body; hide the tab (CDP `Emulation.setDocumentHidden` or the window manager) and confirm the poll loop idles, then refire on return (the phase-18 verification script pattern)

+# Task 02 — GPU data as its own values; GPU-less hosts omit the slot
+
+**Phase:** `21_page_cleanups` · **Source:** `TODO.md:12` — "The GPU data is wrapped poorly - Radeon 8060S Graphics · VRAM 180.2 MiB / 512.0 MiB · pool 79% · 69 °C is too much info for such small text and should be its own values. Boxes without a GPU should not report N/A but instead should omit these values."
+**Story:** n/a
+
+## Objective
+
+The `/system` hero card's GPU slot stops stuffing model · VRAM · pool · temp into one small sub-line: each becomes its own labelled value on the card, at a readable size. A host with no GPU (gateway, the no-GPU capture) no longer renders an `n/a` hero slot — the slot is **omitted** and the hero row simply has five. The API is untouched: `gpus[]` keeps every field (`model`, `vram_used_bytes`, `vram_total_bytes`, `mem_used_pct`, `temp_c`), and the per-card history (`gpu.busy_pct@N`, `gpu.temp_c@N`) and the collapsed GPU chart are unchanged.
+
+## Work
+
+1. `src/dashboards/web/static/page-system.js` — replace `gpuSub()` (lines 150–156) with a `gpuValues(gpu)` that renders four labelled cells — **Model** (mono, the `gpu.model` string), **VRAM** (`used / total` via the existing `bytes()` formatter, `n/a` if either side is absent), **Pool** (`mem_used_pct` %), **°C** (`temp_c`) — laid out as a compact `.gpu-values` grid under the busy hero (the hero itself keeps only the `busy_pct` number + its label; colour rules stay: the GPU is uncoloured, phase 06's "a busy GPU is the job" rule — no severity token, no bar). A missing field on a **present** card prints `n/a` in its own cell (rule 2: the field is absent, the card is real); a `null` verdict cell draws faint, the existing `Dash.hero` convention.
+2. `src/dashboards/web/static/page-system.js` — `renderGpuSlot()` (lines 164–188): when `gpus` is empty, do **not** render the slot's fallback `n/a` content — render nothing (empty the slot's container and drop its hero styling so the row reflows to five heroes; the `data-k="gpus"` wrapper can stay as an empty, zero-footprint element or be removed — pick one and pin it). The multi-GPU case: one value grid per card, the cards' `GPU i` labels unchanged.
+3. `src/dashboards/web/static/dash.css` — the `.gpu-values` grid: a compact 2×2 (or 4×1 on wide) of labelled cells reusing the existing token vocabulary (`.metric`/`.faint`/`.mono` shapes, no new palette — the app's colour rule), sized so a 20-character model string wraps rather than truncates.
+4. `tests/test_api.py` — rewrite the six-heroes pin (line 1425): a host whose snapshot carries `gpus` still renders exactly six slots **in the existing order** (CPU, MEM, TEMP, DISK, GPU, NET); a host with no GPU renders exactly five with **no** `data-k="gpus"` slot (or the pinned empty variant) and no `n/a` in the hero row; the `gpu-values` cells (Model / VRAM / Pool / °C) are present in the served script. `tests/test_system_contract.py` and `tests/card_contract.py` stay green untouched (API fields unchanged).
+5. `AGENTS.md` — (Documentation & Consistency pass) the `/system` paragraph's "a missing number or verdict — gateway's CPU temp, any host's absent GPU — prints `n/a` **uncoloured**" is split: the CPU-temp half keeps the `n/a` rule, the GPU half becomes the omission rule (the TODO is the decision), and the dense-sub-line description of the GPU slot is rewritten to the four-value layout.
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the rewritten hero pin over the three captures (discrete GPU, APU, no-GPU) **and** over HTTP (the `self_test`-style app harness the contract tests use); `tests/test_system_contract.py` + `tests/card_contract.py` green untouched

+# Task 03 — The `/certs` agents table scrolls horizontally
+
+**Phase:** `21_page_cleanups` · **Source:** `TODO.md:9` — "In the certs page I can't horizontal scroll in the agents table to see the certs installed on the hosts."
+**Story:** n/a
+
+## Objective
+
+The `#agents-table` on `/certs` becomes horizontally reachable at phone width: its right-hand columns (the serial, expiry, `san` list and the Rotate / Revoke / bundle controls) are reachable by scrolling instead of being clipped. The repo's own mechanism is the `.scroll` modifier — `dash.css` gives `table.data` a scroll container **only** with that class (the same rule gap 12 measured on `/`'s fleet table), so this is the class, not a second mechanism. Row contents, the `COLUMNS` contract and every served pin are unchanged.
+
+## Work
+
+1. `src/dashboards/web/pages/certs.html` — line 81: `<table class="data" id="agents-table">` gains the `scroll` modifier (`class="data scroll"`), or is wrapped in `<div class="scroll">` — check which form `dash.css`'s selector actually matches (grep `\.scroll` in the file first; use the one it styles, do not invent a third).
+2. `src/dashboards/web/static/dash.css` — if the `.scroll` selector matches `table.data.scroll`, nothing to add; if it matches a `div.scroll > table.data` wrapper, verify the wrapper's max-height/overflow behaviour against the card's padding so the scroll container does not clip the row's own bottom border (measure in a browser, do not deduce). No new token, no new palette.
+3. `tests/test_api.py` — the served-HTML pin: `#agents-table` (or its wrapper, whichever shipped) carries the `.scroll` mechanism in the served bytes; the `COLUMNS`-resolution test (the one that reads the served `COLUMNS` table against a live `GET /api/certs` row in both directions) stays green untouched.
+4. `src/dashboards/web/static/page-certs.js` — lines 55–56 (`table`/`body` lookups): no change expected — the id and the `tbody` selector are untouched by the wrapper/class; verify the page still renders its rows (a wrapper that breaks `getElementById('agents-table')` would be caught by the existing render path).

+# Phase 22 — /disks hides hosts without smartctl
+
+**Source:** `TODO.md` L13 — "VMs that don't have smartctl enabled disks should not show up. Gateway shouldn't even be a host on the disks page."
+**Story:** n/a
+**Context:** `src/dashboards/api.py` (`disks_router()` at line 791 — `/api/disks/snapshot` answering one entry per configured host; the `/api/summary` disks block at lines 640–704 — `disks_hosts` built from `job.state.payload or _disks_stub(...)` at line 640, `fleet_disk_summary(disks_hosts)` at line 693; `_disks_stub()` at line 771 — `smartctl_available: None` for a never-answered host), `src/dashboards/sources/disks.py` (`smartctl_available()` at line 142 — the three-way flag: `True` a disk answered, `False` the agent said the binary is not installed, `None` an agent predating the pass or `--no-smart`), `src/dashboards/web/static/page-disks.js` (the per-host cards + the `fleet_disk_summary` header, hidden below two hosts), `tests/test_api.py` (the `/api/disks/*` pins — "one entry per configured host", the `smartctl_available` three-way, "with and without targets configured", the `fleet_disk_summary` key paths)
+
+## Objective
+
+A host whose agent answered `smartctl_available: false` (the binary is not installed — gateway's VM, no smartmontools behind `vda`) is not a host on the `/disks` page at all: it is absent from `/api/disks/snapshot`, from the fleet block and from `/api/summary`'s disks rows, and the fleet header counts only the hosts that are shown. The **three-way** flag itself is unchanged in `sources/disks.py` (the agent still reports it, the `/disks` page's `null`-case why-line still exists for `None` hosts, and an **unreachable** host keeps its dimmed stub row — a dead agent is a different fact from a missing binary, invariant 3). The filter is one API-level decision, so the source, the store and the health records see nothing new.
+
+## Dependencies
+- `21_page_cleanups` (todo) — both phases touch the `/disks` page markup (task 21.01 removes the page's `#pause` button); landing 21 first keeps this phase's diff confined to the host list.
+
+## Tasks
+1. `01_hide_smartctl_false_hosts.md` — the one API-level visibility gate (explicit `False` only) over `/api/disks/snapshot`, `/api/summary`'s disks block and the fleet summary; the pins rewritten
+2. `02_verification.md` — browser + API verification against the live fleet: gateway absent, deskwork/driveripper intact, fleet header consistent, screenshots
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the rewritten `/api/disks/snapshot` pin (one entry per configured host **whose agent can read its drives** — a `smartctl_available: false` payload is absent, a `None` payload is present, an `unreachable` stub is present), the `/api/summary` disks-block pin (fleet counts over the visible hosts, per-host rows for the visible hosts only), the unchanged `smartctl_available` three-way pin in `sources/disks.py`'s own tests (`tests/test_disks.py` or wherever the flag is pinned — grep `smartctl_available` in `tests/` first)

+- The final pass reviews `README.md` and `AGENTS.md` in full against the project as it stands after this phase — fixing every inconsistency found, **including pre-existing ones not caused by this phase**. AGENTS.md's `sources/disks.py` bullet (the three-way flag's `False` arm — "so the page can say *install smartmontools*") and the `/disks` UI paragraph (the `.banner.info` why-line for `false`) are rewritten: the `false` arm's page-side consequence is now *absence*, and the three-way flag keeps its agent-side meaning; the "gateway answers `smartctl_available: false`" fleet fact gains the "and is therefore not a host on the disks page" clause.
+

+# Task 01 — The one visibility gate: `smartctl_available` is `False` only
+
+**Phase:** `22_disks_hide_unconfigured` · **Source:** `TODO.md:13` — "VMs that don't have smartctl enabled disks should not show up. Gateway shouldn't even be a host on the disks page."
+**Story:** n/a
+
+## Objective
+
+One API-level helper decides disk-page visibility: a host entry is shown when its payload's `smartctl_available` is **not explicitly `False`** — `True` (a disk answered) and `None` (nobody knows: an agent predating the pass, `--no-smart`, or a never-answered stub) stay, `False` (the agent said the binary is not installed) does not. The gate runs over the assembled per-host list in both endpoints, so `fleet_disk_summary()` (which sums whatever it is handed) sees only the visible hosts and its `hosts_total`/`hosts_live` count exactly the page's rows. `sources/disks.py` keeps the three-way flag verbatim — the agent still reports it and the `None`-case why-line still renders.
+
+- ASSUMPTION: **explicit `False` only** is the hide condition. `None` stays visible (an agent that cannot say is not an agent that said *no* — the three-way flag's whole point), and an `unreachable` stub stays visible (invariant 3's rule: a dead agent must not read as "never configured"; its `smartctl_available` is `None` by `_disks_stub`'s shape anyway). The operator's words — "don't have smartctl **enabled**" / "shouldn't **even be a host**" — are the `false` arm; if a `None` host should also vanish, that is a one-clause change to the helper, not a redesign.
+
+## Work
+
+1. `src/dashboards/api.py` — add one small helper next to `_disks_stub` (line 771): `_disk_visible(host: Mapping) -> bool` — `host.get("smartctl_available") is not False` (the explicit-`False` check, spelled out so a `None` payload passes; a docstring naming the three arms).
+2. `src/dashboards/api.py` — `/api/disks/snapshot` (in `disks_router()`, line 791): filter the assembled per-host list through `_disk_visible` before the response is built (the response shape is unchanged — a shorter list, same entry shape).
+3. `src/dashboards/api.py` — the `/api/summary` disks block (lines 640–704): `disks_hosts` (line 640) is filtered through the same helper **before** `fleet_disk_summary(disks_hosts)` (line 693) and before the per-host row loop (lines 695–704), so the fleet counts and the rows agree with `/api/disks/snapshot` by construction — one helper, two call sites, no second copy of the predicate.
+4. `tests/test_api.py` — rewrite the affected pins: the `/api/disks/snapshot` "one entry per configured host" test gains a `smartctl_available: false` host (a `disks:<host>` job whose payload the test harness holds, the `self_test`-style swap the `nut` job's pin uses) and asserts it is **absent** while a `None` host and an `unreachable` stub are **present**; the `/api/summary` disks-block pin asserts the fleet counts over the visible hosts only (e.g. three configured hosts, one `false` → `hosts_total: 2`); the "without targets configured" leg stays green untouched.
+5. `tests/` — locate the `smartctl_available` three-way pin (grep `smartctl_available` in `tests/`; `tests/test_disks.py` or the agent/disks source tests) and confirm it is **untouched** by this change (the flag's computation is unchanged; only the API's reading of it gained a gate).
+
+## Testing & Quality
+- Unit/integration: `tests/test_api.py` — the pins above, both directions (a `false` host absent from **both** endpoints; a `None`/`unreachable` host present in both); the unchanged `fleet_disk_summary` unit tests in `tests/` (the function is untouched — it sums what it is handed)
+- Coverage: **>90%** on this task's new/modified code
+
+## Completion Criteria
+- [ ] `/api/disks/snapshot` and `/api/summary` agree on the visible host set, and neither lists a `smartctl_available: false` host (pinned)

+# Task 02 — Live verification: gateway gone, the rest intact
+
+**Phase:** `22_disks_hide_unconfigured` · **Source:** `TODO.md:13` — "VMs that don't have smartctl enabled disks should not show up. Gateway shouldn't even be a host on the disks page."
+**Story:** n/a
+
+## Objective
+
+The gate is proven on the live fleet, read-only: the dev server (invariant 10: `./scripts/dev-server.sh restart`, sign in with `testpass`) answers `/api/health` with all nine sources `ok`, the `/disks` page shows deskwork and driveripper only, and every number that used to render still renders. No fleet change is made — this task dials the fleet and screenshots it.
+
+## Work
+
+1. `./scripts/dev-server.sh restart` — the dev server up on http://127.0.0.1:8090; `./scripts/dev-server.sh status` — the nine-source table: `host:driveripper`, `host:deskwork`, `host:gateway`, `disks:driveripper`, `disks:deskwork`, `disks:gateway`, `nut`, `llm:gufo`, `llm:vllm` all `ok` (gateway's **agent** still answers — the job is `ok`; only the *page* hides it, which is the point: the `disks:gateway` health record must not be touched by the API filter, and `status` is the proof).
+2. Signed-in `GET /api/disks/snapshot`: no `gateway` entry, `deskwork` and `driveripper` present with their `smartctl_available: true` payloads; `GET /api/summary`: the disks block's `hosts_total` is 2, the per-host rows are the two, and the `system` block still lists all three hosts (the filter is `/disks`-scoped only — a `system` host list that lost gateway would be the over-reach the pin must catch).
+3. Browser on `/disks` (invariant 10): the fleet header reads the two-host sum; gateway has no card and no why-line; deskwork's `nvme0n1` and driveripper's 16 drives render exactly as before the phase (the live SMART numbers from the fleet record); a screenshot in `data/logs/`.
+4. The `None`-arm check: no live host is currently `None` (all three agents post-date the SMART pass), so the `None` arm is proven by the task-01 pins only — state that in the notes rather than fabricating a live case.
+
+## Testing & Quality
+- Coverage: n/a (verification task; the gate's coverage is task 01's)

+# Phase 23 — LLM rate responsiveness
+
+**Source:** `TODO.md` L8 — "The LLM monitor has a strange delay and a 'ramp up/ramp down' effect that makes it look innacurate. Data reporting should be accurate to as small a delta as possible."
+**Story:** n/a
+**Context:** `src/dashboards/app.py` line 122 (`build_hub` builds **one** `RateEstimator(span=settings.rate_window)` and hands it to both `host_jobs` (line 124) and `llm_jobs` (line 130)), `src/dashboards/config.py` lines 197–199 (`llm_interval` 2 s, `llm_timeout` 3 s, `rate_window` 10 s), `src/dashboards/collectors.py` line 477 (`llm_jobs(settings, client, rates)` — the estimator is a parameter, so a second one is a wiring change, not a signature redesign), `src/dashboards/rates.py` (line 55 `MIN_WINDOW_SECONDS = 0.5`, line 61 `MAX_WINDOW_RATIO = 2.0`, the phase-13 jump gate — all untouched by this phase), `src/dashboards/web/static/page-llm.js` (line 39 `pollMs: 2000`, the `Δ<window>` labels printed from the payload's `window`), `src/dashboards/sources/llm.py` (the rate cells carry `computed:Δ<series>/Δt` + the honest `Δ<window>`; the window the estimator *used* travels with the value — rule 2), the mechanism the TODO describes (gap 9 / phase 13 in AGENTS.md: a 10 s window over a 2 s poll ramped the hero up over ~5 polls when a slot started and decayed over ~5 polls when it ended — the "ramp up/ramp down" the operator sees; the sub-8× skew family and the stall are **already** closed by phases 13/14 and stay closed: this phase changes the window size, nothing else)
+
+## Objective
+
+The LLM throughput rates are measured over a window as small as the app's own cadence allows — the LLM source gets its **own** `RateEstimator` whose span is the LLM poll interval (2 s), so a slot start reads steady within two polls instead of ramping over ten, while the `host` source keeps the 10 s `RATE_WINDOW_SECONDS` window its 10 s cadence needs (a 2 s window over a 10 s poll would refuse every window — the estimator's floor and ceiling would answer `n/a` forever). The phase-13 protections (the 0.5 s floor, the `2 × span` ceiling, the 8× jump gate with its independent-anchor confirmation) apply to the smaller window unchanged; the `Δ<window>` label prints the smaller window it actually used, so the number always says what it is.
+
+## Dependencies
+- — (none) — the phase touches `app.py`/`collectors.py` wiring and the LLM page; it is scheduled after `22_disks_hide_unconfigured` only to keep the fleet-changing phase 24 last.
+
+## Tasks
+1. `01_llm_window_per_poll.md` — the second estimator: `build_hub` hands `llm_jobs` a `RateEstimator(span=settings.llm_interval)`, the host keeps the 10 s one
+2. `02_window_pins.md` — the pins: LLM rate cells label the 2 s window, host cells keep 10 s, the phase-13 gates still hold over the smaller window
+3. `03_live_verification.md` — the live proof: a slot start reads steady within two polls (no 10 s ramp), the `Δ2.0s` label travels with the value, screenshots

AGENTS.md's `app.py`/`poller.py` bullets (the "one `RateEstimator`" sentence) and `rates.py`'s docstring context gain the two-estimator fact; gap 9's "the estimator no longer turns a slow fetch into 0.2 s arithmetic" history stays — this phase is the window-size decision on top of it, and the `RATE_WINDOW_SECONDS=10` line in `.env.example` stays (it is the host's knob now, and gains a comment saying so if it has none).
+
+## Completion Criteria

+# Task 01 — The LLM source gets its own 2 s-window estimator
+
+**Phase:** `23_llm_rate_responsiveness` · **Source:** `TODO.md:8` — "The LLM monitor has a strange delay and a 'ramp up/ramp down' effect that makes it look innacurate. Data reporting should be accurate to as small a delta as possible."
+**Story:** n/a
+
+## Objective
+
+`build_hub` builds **two** estimators: the host's keeps `RateEstimator(span=settings.rate_window)` (10 s — its 10 s cadence needs the wide window; a 2 s span over a 10 s poll would sit the window-empty fallback against the `2 × span` ceiling and answer `n/a` every poll), and the LLM's is `RateEstimator(span=settings.llm_interval)` (2 s — one poll interval: the smallest window the 2 s cadence can honestly fill). `llm_jobs` (which already takes the estimator as a parameter, `collectors.py` line 477) receives the LLM one; `HostCollector` keeps the 10 s one. No new env var: the LLM window **tracks** `LLM_INTERVAL_SECONDS`, so the one existing knob stays the single source of truth for the LLM cadence-and-window pair.
+
+- ASSUMPTION: **no new env var** — `RATE_WINDOW_SECONDS` (10, `.env.example` line 85) becomes the host's knob and the LLM window is `llm_interval` by construction. A 2 s window is 4× above the 0.5 s `MIN_WINDOW_SECONDS` floor, so the floor never engages on a healthy cadence; the 8× jump gate stays engaged (a real burst from idle still holds one poll for confirmation), and the poll cadence itself is **unchanged** — gufo and vLLM see exactly the same request rate as before (the TODO asks for a smaller *delta*, not more load on the engines).
+
+## Work
+
+1. `src/dashboards/app.py` — `build_hub` (lines 122–130): `rates` becomes `host_rates = RateEstimator(span=settings.rate_window)`; new `llm_rates = RateEstimator(span=settings.llm_interval)`; `host_jobs(..., HostCollector(host_rates), ...)` unchanged in shape; `llm_jobs(settings, client, llm_rates)` takes the new one. The two estimators are keyed on disjoint series names (rule 2's key is the resolved name + label set), so one shared object was never load-bearing — but the docstring/comment at line 122 (if it says "one estimator for all sources") is rewritten to the two-estimator shape.
+2. `src/dashboards/collectors.py` — line 477: no signature change expected (the parameter is already there); verify the LLM jobs thread `rates` through to `parse_gufo_metrics`/`parse_vllm_metrics` (they already take it, `sources/llm.py` lines 189/243) — if any LLM path constructs its own estimator, it takes the injected one (one estimator per source, the phase's invariant).
+3. `src/dashboards/config.py` — no change expected (the knobs exist); if a comment on `rate_window` (line 199) implies it is the one global knob, it gains the "host's knob; the LLM window is `llm_interval`" clause.
+4. `tests/` — the `build_hub`-level test (grep `build_hub` in `tests/` — the `tests/test_api.py` wiring pins) gains one assertion pair: the estimator the LLM jobs receive has `span == settings.llm_interval` and the host collector's has `span == settings.rate_window` (spy the two objects, the way the `agent_tls_map` pin spies its entry).

+# Task 02 — The pins: 2 s LLM window, 10 s host window, gates intact

+**Story:** n/a
+
+## Objective
+
+The window decision is pinned on the surface that shows it, in both directions (the repo's testing-policy rule): a LLM rate cell answers its `window` ≈ the LLM interval with the `Δ<window>` label traveling with the value, a host rate cell keeps ≈ 10 s, and the phase-13 gate tests — the 0.5 s floor refusal, the `2 × span` ceiling, the 8× jump hold with its independent-anchor confirmation, and the stale-scrape-body regression — run **unchanged** and green, because they are estimator properties, not window-size properties.
+
+## Work
+
+1. `tests/test_llm.py` (or the file the LLM parse tests live in — grep first) — the two window pins: (a) a gufo metrics scrape driven through `parse_gufo_metrics` with a `RateEstimator(span=2.0)` (the `build_hub` shape, task 01's) answers the rate cell with a `window` in `(0.5, 2.0]` on a healthy 2 s cadence and the cell's `source` string still reads `computed:Δ<series>/Δt`; (b) the same test shape with `span=10.0` on the host's series (or the existing host fixture tests) keeps its `window` ≈ 10 s — the two sources' windows are **different numbers in the same payload shape**, and a pin that asserts only one of them is the gap this task closes.
+2. `tests/test_rates.py` (or wherever the phase-13 tests live) — run them unchanged: the floor test (a sub-0.5 s window answers `(None, dt)`), the ceiling test (`2 × span`), the jump-gate test (≥8× holds one poll, publishes on a *different-anchor* confirmation) and the two stale-body regression tests. If a test constructs its estimator with an explicit `span` that now disagrees with the app's shape, it is **not** edited to match — the estimator's constants are app-independent and the tests' own spans are theirs (the app's shape is task 01's pin's job).
+3. `tests/test_api.py` — the `/api/llm/snapshot` shape pins stay green (the shape is unchanged; only `window` values move). If a pin hard-codes a `window` number in the LLM payload, it is the one place it is updated — to a range assertion (`0.5 < window <= 2.0 × llm_interval`), not a literal, so a future cadence change does not rot it.
+4. `tests/test_config.py` — confirm `rate_window`'s pin (the 10 s default) stays; no new setting was added, so no new pin is needed (the "no new env var" ASSUMPTION is what the absence of a new setting is).

+# Task 03 — Live verification: the ramp is gone
+
+**Phase:** `23_llm_rate_responsiveness` · **Source:** `TODO.md:8` — "The LLM monitor has a strange delay and a 'ramp up/ramp down' effect that makes it look innacurate."
+**Story:** n/a
+
+## Objective
+
+The smaller window is proven on the live engines, read-only: with the dev server up (invariant 10) and a decode workload running on the engines, the `/llm` hero reaches steady state within **two** polls of the slot starting (pre-phase it ramped over ~five) and decays within two of it ending, every value carrying its `Δ2.0s` label, and the stored 1 m rollups staying in the fleet's measured band (gap 9's pass line: anything above ~300 tok/s is arithmetic, not work). No engine is written to — the workload is whatever the operator's engines are doing, or a deliberately short local decode the operator starts; a live test that loads a shared engine is not a test.
+
+## Work
+
+1. `./scripts/dev-server.sh restart`, sign in with `testpass`; `./scripts/dev-server.sh status` — the nine-source table `ok` (a restart also proves the two-estimator wiring survives a real boot, not just the in-memory test store).
+2. Signed-in polling of `/api/llm/snapshot` at 2 s (a short script, the `scripts/watch-store-perf.py` pattern): capture the decode tok/s cell's `value` + `window` for ~60 s while a slot is busy, then again for ~30 s after it frees. The pass shape: within two polls of the transition the value is within 8× of steady (the jump gate's own ratio — a held value is the designed behaviour, and a *confirmation* within the next poll is the honest publish; a value still ramping at poll 5 is the pre-phase defect returning).
+3. The `Δ` label check (gap 9's rule, restated): **zero** values printed without their `Δ<window>` label; the label reads the window actually used (`Δ2.0s` on a healthy cadence, the honest sub-window — never a bare number — when the floor or the stall engages).

+# Phase 24 — Dev mTLS: no non-mTLS agent, ever
+
+**Source:** `TODO.md` L3 — "The client should never allow non-mtls communication. deskwork and gateway are still non-mtls according to the dashboard. During dev, the dev server should generate certs in a non-committed directory and then distribute them to clients during registration so we never need non-mtls servers."
+**Story:** n/a
+**Context:** phase 15 (complete) — the durable CA in `meta` (`certs.py`: five `certs.*` rows, the bundle stored verbatim), the agent's TLS mode (`agent/host_agent.py` 1.1.0: `--cert-bundle`, `CERT_OPTIONAL`, the live `# REVOKED` denylist, `agent.tls`/`agent.bundle_rev` in the snapshot), the collector's certificate dial (`collectors.py` `AgentTls` — an `https://` `HOST_TARGETS` entry dials with this app's client certificate), the bundle download route (`GET /api/certs/<name>/bundle`, session-gated, the stored bytes verbatim), the installer's `--cert-bundle` shape check (`deploy/install-agent.sh` lines 270–331 — the python3 validator runs **before** `need_root`, the bundle installs `0640 root:dashboards-agent` at line 385, the `--status` https probe), and the fleet record (AGENTS.md gap 11: no bundle is installed on any host, `HOST_TARGETS` is `http://` for every host, the installed agents run 1.0.0 so **1.1.0 ships together with the bundle, never the bundle alone**; gap 10: driveripper's unit is reproducible only with the repo script's `--as-root --caps CAP_SYS_RAWIO CAP_SYS_ADMIN --force` line — the Oct-18 sudo-granted snapshot must not be run; deskwork's `ops` has no installer grant, so its install goes through the operator's root). `scripts/dev-server.sh` (the dev server: reads `.env.dev`, nohup `dashboards`, `/api/health` readiness probe, `status` subcommand) and `data/` (gitignored — the non-committed directory the TODO names)
+
+## Objective
+
+The dev loop stops producing `http://` agents. On start, the dev server exports every configured host's stored bundle to non-committed `data/certs/` (the CA is already durable in `meta` — "generate" means *materialise what the first boot minted*, never a second authority), and the installer gains `--fetch-bundle` so a client's **registration** — its install — pulls its bundle from the dashboard and installs it in the same run (the operator no longer curls a file across the network by hand). Then the fleet itself moves: agent 1.1.0 + bundle on deskwork, driveripper and gateway, `HOST_TARGETS` flipped to `https://` host by host (a URL flipped before its bundle is installed turns that host red by construction — the order is the safety), leaving the dashboard's nine sources `ok` with three `agent.tls: true` hosts and no `http://` agent URL anywhere.
+
+## Dependencies
+- — (none) — the phase builds on complete phase 15 and phase 17; it is scheduled last on purpose, because it is the fleet-changing one.
+
+## Tasks
+1. `01_dev_bundle_export.md` — `scripts/dev-certs-export.py` + `dev-server.sh`: the dev server writes every configured host's bundle to `data/certs/<name>.bundle` (`0600`) on start; an unissued host says so and writes nothing
+2. `02_installer_fetch_bundle.md` — `install-agent.sh --fetch-bundle <url> --cert-name <name> --session <token>`: registration pulls the bundle from the dashboard, the shape check runs on the fetched bytes before `need_root`, the token never reaches the token file or the unit
+3. `03_fleet_rollout.md` — agent 1.1.0 + bundle on the three hosts (deskwork via the operator's root, driveripper with the gap-10 `--force` line, gateway with its sudoers grant), `HOST_TARGETS` flipped per host, the URL never flipped before the bundle
+4. `04_verification.md` — the fleet is mTLS: `agent.tls`/`deployed_bundle_rev` agree for all three hosts, nine sources `ok`, no `http://` agent URL, the 16-driver SMART reads still live, screenshots
+
+## Testing & Quality
+- Unit/integration: `tests/test_deploy_scripts.py` — the export helper against a `create_app(...)` hosted on a socket (the sandbox pattern the installer tests already use: fake `install`/`chown` where the installer runs); the `--fetch-bundle` legs (a good bundle fetched, installed and byte-identical; a malformed one refused **before any write**; the token absent from every written artefact)
+- Coverage: **>90%** on new/modified code
+- The phase is "Complete" only when the **entire** project test suite passes 100% (every test in the project, not just this phase's)
+
+## Documentation & Consistency
+
+- The final pass reviews `README.md` and `AGENTS.md` in full against the project as it stands after this phase — fixing every inconsistency found, **including pre-existing ones not caused by this phase**. The README's *Protecting an agent, host by host* rollout becomes the `--fetch-bundle` recipe (the manual curl is demoted to the fallback), the dev section gains the `data/certs` export, AGENTS.md's fleet record and gap 11 resolve to "all three hosts mTLS since <date>" with the exact installed units, and the "bearer-token transport is the compatibility path, not the designed one" sentence becomes history. **No token, no PEM and no session value go into any tracked file** — the exported bundles live in gitignored `data/`, the fleet's `HOST_TARGETS` URLs carry no userinfo once flipped (invariant 6), and the task transcript names hosts, not credentials.
+
+## Completion Criteria
+- [ ] `./scripts/dev-server.sh restart` leaves `data/certs/<name>.bundle` for every configured host that has an issued bundle, `0600`, byte-identical to the stored row, and a one-line note for any unissued host (pinned + verified)
+- [ ] `sudo deploy/install-agent.sh --fetch-bundle <url> --cert-name <host> --session <token> ...` installs a byte-identical bundle in the sandbox, refuses a malformed one before `need_root`, and leaves no token in the token file, the unit or the log (pinned)
+- [ ] all three hosts run agent 1.1.0 from an installed bundle, `HOST_TARGETS` is `https://` for every host with no userinfo, and `./scripts/dev-server.sh status` reads nine sources `ok` with `agent.tls: true` and `deployed_bundle_rev == bundle_rev` on all three (screenshots of `/certs` in `data/logs/`)

+# Task 01 — The dev server exports the bundles to `data/certs/`
+
+**Phase:** `24_dev_mtls_rollout` · **Source:** `TODO.md:3` — "During dev, the dev server should generate certs in a non-committed directory and then distribute them to clients during registration…"
+**Story:** n/a
+
+## Objective
+
+On start, the dev server materialises the **stored** CA's per-host bundles in non-committed `data/certs/`: one `0600` file per configured host with an issued bundle (`data/certs/<name>.bundle`, byte-identical to the `meta` row the bundle route serves — the CA is durable in `meta`, so "generate" is an export of what the first boot already minted, never a second authority; `data/` is gitignored, so nothing committed ever carries a key). A configured host with **no** issued bundle (the invariant-3 shape: `issued: false`) writes no file and prints one line naming the host and the `/certs` route that issues it. The export is a small standalone script the dev server calls, so the test suite drives it against a `create_app(...)` hosted on a socket without a nohup'd process.
+
+## Work
+
+1. `scripts/dev-certs-export.py` — a standalone helper (stdlib `urllib`, the way `install-agent.sh`'s validator uses `python3`): arguments `--url` (the dev server's base URL), `--password` (the sign-in password — the dev server reads it from the same `.env.dev` it already loads, so the value comes from the environment, never a tracked file), `--names` (the configured host names, space-separated — read from `HOST_TARGETS`' names, the same parsing `parse_targets` does, passed in by the caller rather than re-parsed inside), `--out-dir` (defaults to `<root>/data/certs`). Behaviour: sign in via `POST /api/auth/login` (the public route; the token travels in `Authorization` for the bundle GETs), then per name `GET /api/certs/<name>/bundle` — a `{"configured": true, "issued": false}` answer writes **no file** and prints the one-line note; a configured host that 404s (`{"configured": false}`) is impossible by construction (names come from `HOST_TARGETS`) but is handled as the same no-file line, not a crash; a good bundle is written `<out-dir>/<name>.bundle` at `0600` (created via `os.open`, not `open()`, so the mode is the file's birth mode). The script exits 0 when every name resolved to either a file or the no-issued note, and non-zero on a sign-in failure — a dev server that cannot sign in says so in `dev-server.sh`'s start output, never silently.
+2. `scripts/dev-server.sh` — in `start()`, after the readiness probe: call the export (`.venv/bin/python scripts/dev-certs-export.py --url http://127.0.0.1:$PORT --password "$DASH_ADMIN_PASSWORD" --names <the HOST_TARGETS names> --out-dir $ROOT/data/certs`), printing its per-host lines; in `status`, print the `data/certs/` listing (names + sizes) as the "bundles exported" block. The export failure is a **warning line**, not a `start` failure — a bundle export that cannot sign in is a dev-convenience failure, and the server itself is up (the readiness probe already proved it); the one line says what to check.
+3. `tests/test_deploy_scripts.py` — the pin: host `create_app(settings with admin_password="testpass", pbkdf2_iterations=1000, one or two configured targets, an in-memory store with an issued bundle for one host and none for the other)` on `127.0.0.1:0` via `uvicorn` (the project's own dependency — `__main__.py`'s pattern), run the script against it, and assert: the issued host's file exists at `0600` and is **byte-identical** to `GET /api/certs/<name>/bundle` from the same app; the unissued host wrote **no file** and the output carries its one-line note; a wrong `--password` exits non-zero and writes nothing.

+## Testing & Quality
+- Unit/integration: the pin above (the sandbox pattern `tests/test_deploy_scripts.py` already uses for the installer)
+- Coverage: **>90%** on this task's new/modified code
+- Real-boot check: `./scripts/dev-server.sh restart` on the dev box prints the per-host export lines and `data/certs/` holds the files (the dev box is the test bed — invariant 10)
+
+## Completion Criteria
+- [ ] `./scripts/dev-server.sh restart` leaves `data/certs/<name>.bundle` per issued host, `0600`, byte-identical to the stored row; an unissued host is a one-line note and no file (pinned + verified on the dev box)
+- [ ] `status` prints the exported-bundles block

+# Task 02 — `install-agent.sh --fetch-bundle`: registration pulls the bundle
+
+**Phase:** `24_dev_mtls_rollout` · **Source:** `TODO.md:3` — "…then distribute them to clients during registration so we never need non-mtls servers."
+**Story:** n/a
+
+## Objective
+
+The installer's registration moment — the install — is where the client gets its bundle: `--fetch-bundle <dashboard-url> --cert-name <name> --session <token>` fetches `GET /api/certs/<name>/bundle` from the dashboard **in the install run**, the existing python3 shape check (lines 270–331, which runs before `need_root`) validates the **fetched bytes**, and the rest of the `--cert-bundle` path (the `0640 root:dashboards-agent` install at line 385, the unit's `--cert-bundle` + `RuntimeDirectory` lines, the `--status` https probe) runs on them unchanged. The session token is a **fetch credential only**: it never reaches the agent's token file, the unit, the log or the installed bundle, and the fetch happens before `need_root` (a host whose dashboard refuses the fetch never gets a partial install — the same order the bundle validator already has).
+
+- ASSUMPTION: the session travels on **argv** (`--session <token>`), matching how the operator already signs in for the manual curl the README's rollout documents; the token is visible in the `sudo` process list for the fetch's duration, which is the accepted cost on a single-admin box (the alternative — a `0600` session file — is a second artefact to clean and the operator's muscle memory is the curl recipe). The three flags are **all-or-nothing**: any one without the others is refused with a usage line before `need_root` and before any write.
+
+## Work
+
+1. `deploy/install-agent.sh` — argument parsing (near line 136): `--fetch-bundle) FETCH_URL="$2"; shift 2 ;;`, `--cert-name) CERT_NAME="$2"; shift 2 ;;`, `--session) SESSION_TOKEN="$2"; shift 2 ;;`; the all-or-nothing check (the three set together or not at all; `--fetch-bundle` and a local `--cert-bundle <file>` together is refused — two bundle sources are a contradiction, pick one) in the same pre-`need_root` region the bundle validator occupies (lines 160–331).
+2. `deploy/install-agent.sh` — the fetch: a `python3` `urllib` block (the script already requires `python3` for the shape check — no new dependency, no `curl` assumption): `GET $FETCH_URL/api/certs/$CERT_NAME/bundle` with `Authorization: Bearer $SESSION_TOKEN` written to a `mktemp` file; the response body's shape is checked in the same block — a `{"configured": true, "issued": false}` body is refused with its own one-line reason (*"no bundle issued for <name> — issue it from /certs first"*), a `404`/`401`/`403` is refused naming the HTTP status, and only a 200 with a non-empty body falls through to the **existing** shape check (lines 270–331) run on the temp file; on any refusal the temp file is deleted (`trap`-covered, the way the script already cleans its unit temp file) and nothing is written. On success the temp file is handed to the existing `BUNDLE_SRC` path — the `0640` install, the unit lines and the `--status` probe all run unchanged on the fetched bytes.
+3. `deploy/install-agent.sh` — token hygiene: `SESSION_TOKEN` is used only in the fetch block; it is never `echo`d (the script's existing log lines name the URL, never the header), never written to `$TOKEN_FILE`/`$CERT_FILE`/the unit, and is `unset` after the fetch; the `--help` block gains the three flags with the one-line recipe (the URL is the dashboard's, the name is the `HOST_TARGETS` name, the session is the signed-in token).
+4. `tests/test_deploy_scripts.py` — the pins (the sandbox pattern: fake `install`/`chown`, a local `http.server` thread serving the bundle route's exact bytes — the `application/x-pem-file` attachment body a `create_app` bundle route would serve): (a) a good fetch → the installed `CERT_FILE` is **byte-identical** to the served bytes, `0640`, and the unit carries the `--cert-bundle` line; (b) a served `{"configured": true, "issued": false}` body → refusal with the one-line reason, **no** `install` call (the fake records it), temp file gone; (c) a served 401 → refusal naming the status, no write; (d) the **token absence** pin: the token string appears in no written artefact — not the token file, not the unit, not the script's captured stdout (the test serves the bundle with a token it chose and greps the sandbox for it); (e) the all-or-nothing and the two-bundle-source refusals, both before `need_root` (the sandbox's root check records the call order).

+# Task 03 — The fleet goes mTLS, host by host
+
+**Phase:** `24_dev_mtls_rollout` · **Source:** `TODO.md:3` — "The client should never allow non-mtls communication. deskwork and gateway are still non-mtls according to the dashboard."
+**Story:** n/a
+
+## Objective
+
+All three agents run 1.1.0 from an installed bundle, and `HOST_TARGETS` is `https://` for every host. The order per host is the safety (gap 11's rule: **a URL flipped before its bundle is installed turns that host red by construction**): install agent 1.1.0 + bundle → restart the unit → the `--status` CA-only https probe answers → **then** the `HOST_TARGETS` line flips → the dev server restarts → `agent.tls` shows. 1.1.0 ships **together with** the bundle, never the bundle alone (the installed agents are 1.0.0 — gap 11's re-check). Hosts in order: gateway (the trivial one: `(ALL) NOPASSWD: ALL`, a VM with the standard unit), deskwork (no `ops` installer grant — its root half is the operator's action), driveripper (the gap-10 line, the one that must not be the Oct-18 snapshot).
+
+- ASSUMPTION: the executor has **ssh as `ops`** from the dev box (the fleet record's probes ran from this laptop; the repo's dev workflow dials the fleet from here). If ssh is unavailable in the run environment, the task degrades to its written form: the exact command blocks are printed for the operator, the operator applies them, and task 04's verification runs against the applied fleet — the pass criteria are the same either way.
+- ASSUMPTION: the flipped URL is **clean `https://<host>:9120` with no userinfo** — the TLS handshake is the auth, the token file line stays in the unit (the rollback path), and invariant 6's "no token in a tracked file" is satisfied by `.env.dev` itself being gitignored with the token now out of the URL. **Rollback** per host = restore the pre-flip URL line from the timestamped backup copy (made in `data/env-backup/` before any flip) and restart the dev server — the bundle stays installed, the unit keeps both its token file and the bundle line.
+
+## Work
+
+1. **Prep (dev box):** `./scripts/dev-server.sh restart` (task 01's export leaves `data/certs/` populated); sign in, note the session token (it lives only in the operator's shell and the task transcript's redaction, never in a file); `cp .env.dev data/env-backup/.env.dev-<timestamp>` (gitignored).
+2. **gateway** (`10.1.1.27:9120`, the standard unit): over ssh as `ops` — copy the repo's `agent/host_agent.py` (1.1.0) to `/usr/local/lib/dashboards-agent/host_agent.py`, then `sudo deploy/install-agent.sh --bind 10.1.1.27 --port 9120 --fetch-bundle http://127.0.0.1:8090 --cert-name gateway --session <token>` (the fetch dials the **dev server on the dev box** — the dashboard's bundle route; on a host that cannot reach the dev box, the same flag with the dashboard's LAN URL, or task 01's exported file, is the fallback; the unit gains the `--cert-bundle` + `RuntimeDirectory` lines and keeps its `--token-file` line), `systemctl restart dashboards-agent`, `./deploy/install-agent.sh --status` (the CA-only https probe answers). **Then** flip gateway's `.env.dev` line to `https://10.1.1.27:9120`, `./scripts/dev-server.sh restart`, confirm `host:gateway`/`disks:gateway` `ok` with `agent.tls: true`.
+3. **deskwork** (`10.1.0.51:9120`, the operator's root half): `ops` has no installer grant on deskwork (the fleet record), so the executor prints the exact block — the agent-file copy, `sudo deploy/install-agent.sh --bind 10.1.0.51 --port 9120 --fetch-bundle <dashboard url> --cert-name deskwork --session <token>`, the restart, the `--status` probe — for the operator to run as root; the executor then verifies the unit state over ssh (`systemctl is-active`, `systemctl cat`), flips the URL line and confirms `host:deskwork`/`disks:deskwork` `ok` with `agent.tls: true` (if the operator's run and the flip land before the executor's verify, the verify is the check; the command block is the record).
+4. **driveripper** (`10.1.0.126:9120`, the gap-10 line): over ssh as `ops` — copy the repo's `agent/host_agent.py` (1.1.0) to `/usr/local/lib/dashboards-agent/host_agent.py`, then the **repo's** script with the gap-10 line exactly: `sudo deploy/install-agent.sh --bind 10.1.0.126 --port 9120 --as-root --caps CAP_SYS_RAWIO,CAP_SYS_ADMIN --force --fetch-bundle <dashboard url> --cert-name driveripper --session <token>` (the `--force` is what lands the unit change — task 17's guard refuses a differing re-run without it, and the line reproduces the `User=root` + `CapabilityBoundingSet` unit that keeps all 16 SMART reads live; **never** the Oct-18 sudo-granted snapshot — it predates the flags and the guard), `systemctl restart dashboards-agent`, the `--status` probe, **then** flip the URL line and confirm `host:driveripper`/`disks:driveripper` `ok` with `agent.tls: true` and the 16 drives still reading (a `smart: null` row here is the `--force` rewrite having changed the unit — stop and diff the unit against the fleet record's shape before anything else).
+5. **Fleet state:** after all three flips, `.env.dev`'s `HOST_TARGETS` has no `http://` agent entry and no userinfo token; the three units still carry their `--token-file` lines (the rollback path); the transcript in `data/logs/` names hosts, ports and revs — no token, no PEM.

+# Task 04 — The fleet is mTLS: the end state, verified
+
+**Phase:** `24_dev_mtls_rollout` · **Source:** `TODO.md:3` — "…so we never need non-mtls servers."
+**Story:** n/a
+
+## Objective
+
+The end state is proven read-only, the way phase 15's task-05 final pass proved its composition: the dashboard dials all three agents with its client certificate, the issued-vs-deployed revisions agree, nothing non-mTLS is left in the config, and the things the bundle install must not have broken (driveripper's 16 SMART reads, deskwork's GPU row) still work. No live revocation is performed — the revocation wiring is phase 15's e2e proof (`data/logs/verify-15-tls-e2e.py`), and a live revoke of a working fleet is a change, not a check.
+
+## Work
+
+1. `./scripts/dev-server.sh status` — the nine-source table `ok` (`host:driveripper`, `host:deskwork`, `host:gateway`, `disks:driveripper`, `disks:deskwork`, `disks:gateway`, `nut`, `llm:gufo`, `llm:vllm`); `disks:gateway` is `ok` with the page hiding gateway (phase 22's gate) — the job healthy, the page scoped.
+2. Signed-in `GET /api/certs`: all three rows `status: "active"`, `deployed_bundle_rev == bundle_rev` (the "install the new bundle" sentence is gone for every host), `agent` block from the `system` payload: `agent.tls: true` + `agent.bundle_rev` present on all three (the task-03 passthrough — a token-mode snapshot grows nothing, so the fields' **presence** is the mTLS proof, rule 2's shape).
+3. Signed-in `GET /api/system/snapshot` + `GET /api/disks/snapshot`: the `agent` blocks on all three hosts; gateway's row absent from `/disks` (phase 22); driveripper's 16 drives with live SMART numbers (the `--force` unit rewrite is the gap-10 shape — a `smart: null` row here fails the task); deskwork's `nvme0n1` row and its GPU card on `/system` (the 1.1.0 agent file's reads intact).
+4. The config: `grep` of `.env.dev` — no `http://` in `HOST_TARGETS`, no `@` userinfo in any target URL; `data/env-backup/` holds the pre-flip copy (the rollback path exists on disk).
+5. The negative control, **without touching the fleet**: `data/logs/verify-15-tls-e2e.py`'s transcript (phase 15) is the standing proof that a revoked serial is refused on `/health` too; this task re-runs **none** of it live — it names the transcript as the control and checks only that `tests/test_collectors.py`'s revocation-before-dial pin and `tests/test_api.py`'s `build_hub` wiring pin are green (they run in the suite).
+6. Screenshots (invariant 10) in `data/logs/`: `/certs` (the three active rows with matching revs), `/disks` (the two visible hosts, driveripper's 16 live rows), `/system` (deskwork's GPU card) — the "the dashboard says all three are mTLS" proof is a screenshot, not a curl.

+# Phase 25 — Masthead control placement: badges everywhere, right-justified, clock rightmost
+
+**Source:** `TODO.md` L3–L5 — "hosts disks engines UPS disappear when in the certs/account page" · "I made a mistake earlier, I did want hosts disks engines UPS badges and certs/account/dark right justified don the navbar" · "The time should show up as the farthest right item on the navbar"
+**Story:** n/a
+**Context:** phase 20 (complete) — the masthead is three rows at every width (row 1 brand + `#nav-toggle` + the five tabs, row 2 the `#nav-status` per-source dots, row 3 the `.masthead-right` controls), not sticky (`position: relative`, `z-index: 40`), with the ≤640px dropdown sliding on `nav.tabs.is-open`; phase 18 — the hamburger reveal through `--nav-toggle-display`. The dots are built by `Dash.initChrome()` in `src/dashboards/web/static/app.js` (the `if (nav)` block on `#nav-status`, one chip per `system`/`disks`/`llm`/`ups` dashboard from `/api/health`, refreshed every 15 s), and exist in the markup only of the five dashboard pages — `certs.html` and `settings.html` ship no `#nav-status` (the comment in `settings.html` says a session page "has no fleet reachability to report"), which is what L3 names. The served-CSS pins for the bar are in `tests/test_api.py`: `test_the_masthead_is_three_left_justified_rows_at_every_width` (the two `justify-content: flex-start` declarations, the two `flex-basis: 100%` row breaks, the `min-height`/`gap`), `test_the_mobile_masthead_block_declares_no_second_bar_height`, `test_the_masthead_scrolls_away_and_stays_the_dropdown_anchor`; the one-loop control-order audit is `test_every_page_links_to_both_admin_pages` (clock → `⚷ Certs` → `⚙ Account` → theme toggle on all eight signed-in pages), and the two pins that assert the admin pages have **no** dots are in `test_the_settings_page_is_not_one_of_the_dashboards` and `test_the_certs_page_is_a_page_and_not_a_sixth_dashboard`. `tests/test_auth_api.py` asserts `/login` carries no `#nav-status` — unchanged by this phase.
+
+## Objective
+
+The four per-source badges (hosts · disks · engines · UPS) render on **every** page that renders the masthead — including `/certs` and `/settings` — and the two right-hand rows (the dots, the controls) are right-justified, with the clock the farthest-right item on the bar. The three-row shape at every width is preserved; only the alignment and the control order move, and the clock's position is what L5 asks for.
+
+## Dependencies
+- — (none) — the phase builds on complete phase 20 and phase 18; it is scheduled first of the three appended phases on purpose, because the mobile audit phase (27) measures the masthead in the shape this phase leaves it in.
+
+## Tasks
+1. `01_status_dots_on_admin_pages.md` — `#nav-status` on `/certs` and `/settings` (markup only — `initChrome` already builds the dots when the container exists); the two no-dots pins flip to dots-present
+2. `02_right_justify_masthead_rows.md` — `justify-content: flex-end` on `#nav-status` and `.masthead-right`, the comment block re-worded, the three-rows pin re-pinned to the new alignment
+3. `03_clock_rightmost.md` — the clock moves to the end of the control row on all eight signed-in pages; the one-loop order pin updated; the phase's real-browser verification (badges on the admin pages, both rows right-justified, clock rightmost, at 1280 px and 360 px)
+
+## Testing & Quality
+- Unit/integration: the served-byte pins in `tests/test_api.py` — the flipped admin-page pins (task 01), the re-pinned row-alignment pin (task 02), the updated control-order pin (task 03); `tests/test_auth_api.py`'s `/login`-has-no-dots pin must stay green untouched
+- Coverage: **>90%** on new/modified code (the new code is the pins themselves; the change is CSS and template markup)
+- Real-browser check (invariant 10): a `data/logs/25-task03-*.cjs` script in the `20-task01-rows.cjs` convention, run against the restarted dev server at 1280 px and 360 px on all seven tabbed pages plus `/login` (unsigned), with screenshots in `data/logs/`
+
+## Documentation & Consistency
+
+- The final pass updates the now-stale sentences in `AGENTS.md`: "The masthead is three **left-justified** rows at every width" (alignment), "A page with no dots (`/certs`, `/settings`) renders two rows" (gone — all masthead pages carry the dots), "the two links therefore sit on all eight signed-in pages in one order (clock → `⚷ Certs` → `⚙ Account` → theme toggle)" (new order: `⚷ Certs` → `⚙ Account` → theme toggle → clock), and the "left-justified" wording in the `dash.css` header comment. `README.md` is checked for the same sentences; none is expected.

+# Task 01 — The badges render on the admin pages too
+
+**Phase:** `25_masthead_control_placement` · **Source:** `TODO.md:3–4` — "hosts disks engines UPS disappear when in the certs/account page" · "I made a mistake earlier, I did want hosts disks engines UPS badges and certs/account/dark right justified don the navbar"
+**Story:** n/a
+
+## Objective
+
+`#nav-status` exists in the `.masthead-right` of `/certs` and `/settings`, exactly as it does in the five dashboard pages, so `Dash.initChrome()` builds the four badges (`hosts`/`disks`/`engines`/`UPS`) there without any change to `app.js` — the "disappear when in the certs/account page" symptom is the missing container, and the fix is the container.
+
+## Work
+
+1. `src/dashboards/web/pages/certs.html` — add `<div id="nav-status" class="gap" aria-live="polite"></div>` as the **first** child of `<div class="masthead-right">` (before the `<span class="clock">`), the same position the five dashboard pages use (`index.html:23` is the reference).
+2. `src/dashboards/web/pages/settings.html` — the same addition, and delete the `<!-- No `#nav-status`: a session page has no fleet reachability to report, and `Dash.initChrome()` builds the dots only when the container exists. -->` comment — the premise it states is what the operator overruled (the badges report the fleet, and the fleet is the point of the site, on every page).
+3. `src/dashboards/web/static/app.js` — **no change** (stated so the executor does not "improve" it): `initChrome()`'s `if (nav)` block already builds the four chips and refreshes them from `/api/health` every 15 s whenever `#nav-status` exists; `setDot`'s `idle` state already covers a dashboard the page's config does not run.
+4. `tests/test_api.py` — flip the two pins, one assertion each: in `test_the_settings_page_is_not_one_of_the_dashboards`, `assert 'id="nav-status"' not in html` becomes `in html` (message re-worded: the session page grew the badges the operator asked for); in `test_the_certs_page_is_a_page_and_not_a_sixth_dashboard`, the same flip, and the docstring sentence "no `#nav-status` (a CA page has no fleet reachability to report)" is re-worded to the new fact. `test_the_certs_page_is_a_page_and_not_a_sixth_dashboard`'s other assertions (zero `aria-current`, the tab strip, the head) are untouched, and `tests/test_auth_api.py`'s assertion that **`/login`** has no `#nav-status` is untouched — `/login` still renders the brand link and the theme toggle only.

+# Task 02 — The dots row and the controls row are right-justified
+
+**Phase:** `25_masthead_control_placement` · **Source:** `TODO.md:4` — "I made a mistake earlier, I did want hosts disks engines UPS badges and certs/account/dark right justified don the navbar"
+**Story:** n/a
+
+## Objective
+
+Phase 20 task 01 made the two right-hand rows of the masthead flush left; this task moves them flush **right**. The mechanism is two declarations — `justify-content: flex-end` on `#nav-status` and on `.masthead-right` — and nothing else: the row breaks (the two `flex-basis: 100%` items inside the `flex-wrap: wrap` bar), the `min-height`, the gaps and the ≤640px block all stay exactly as they are, so the bar is still three rows at every width and the phone's wrapped control row still wraps *within itself*.
+
+- ASSUMPTION: the three-row shape is preserved at every width and only the alignment changes. A return to the old single-row bar is not the ask — the row breaks are what make the bar fit at 360 px (phase 18/20 measured that), and the operator's word is "right justified in the navbar", not "one row".
+
+## Work
+
+1. `src/dashboards/web/static/dash.css` — two declarations: `#nav-status`'s `justify-content: flex-start` becomes `flex-end`, and `.masthead-right`'s `justify-content: flex-start` becomes `flex-end`. `margin-inline-start: auto` stays **absent** from `.masthead-right` (the old single-row right-pinning is gone; `flex-end` on a full-basis row is the alignment now).
+2. `src/dashboards/web/static/dash.css` — re-word the comments that state the old alignment, so a future reader is not sent to a left-justified bar that no longer exists: the header comment block (the "three left-justified rows at every width" sentence, and its row-2/row-3 descriptions), the `Row 3:` comment above `.masthead-right` (which currently cites the old `TODO.md` word for `flex-start` — the new sentence states the operator overruled it: the badges and the cluster are right-justified), the `Row 2:` comment above `#nav-status`, and the ≤640px block's comment "Row 3 alignment is the base rule's `flex-start`, restated nowhere" (now `flex-end`). The `#nav-toggle { margin-inline-start: auto }` line in the mobile block is **unchanged**: the hamburger sits at the right of row 1 (brand + toggle + tabs), which is where a phone's thumb already is — it was never part of the right-justified cluster.
+3. `tests/test_api.py` — rename `test_the_masthead_is_three_left_justified_rows_at_every_width` to `test_the_masthead_is_three_rows_right_justified_at_every_width` and change its two alignment assertions from `== "flex-start"` to `== "flex-end"` (the dots line and the cluster line), re-wording the assertion messages and the docstring ("two of them flush left" → "two of them flush right"). Every other assertion in the test stays: `flex-wrap: wrap`, the `flex-direction: row` check, the no-`height`/`min-height: var(--header-h)` pair, the gap, the two `flex-basis: 100%` row breaks, and the "no `margin-inline-start` on the cluster" guard — the row-break mechanism is exactly what must survive the re-justify.
+4. `tests/test_api.py` — `test_the_mobile_masthead_block_declares_no_second_bar_height` and `test_the_masthead_scrolls_away_and_stays_the_dropdown_anchor` stay green **unchanged** (neither reads `justify-content`); confirm they do not need a word change in their docstrings before moving on.

+# Task 03 — The clock is the farthest-right item, and the phase's browser proof
+
+**Phase:** `25_masthead_control_placement` · **Source:** `TODO.md:5` — "The time should show up as the farthest right item on the navbar"
+**Story:** n/a
+
+## Objective
+
+On a right-justified control row, the farthest-right item is the **last** one in markup order, so the clock moves from the first control (before `⚷ Certs`) to the last control (after the theme toggle). The new order on all eight signed-in pages is `⚷ Certs` → `⚙ Account` → `☾ Dark` → clock. This is the phase's verification task as well: the layout change is CSS + markup, so the served-byte pins cannot say the rows actually render right-justified — this task measures them in a real browser (invariant 10).
+
+- ASSUMPTION: "farthest right" is achieved by markup order (the clock is the last child of `.masthead-right`), not by a CSS `order` declaration — the one-loop order pin compares markup, and a `order:` property the pin cannot see is a drift waiting to happen.
+
+## Work
+
+1. The seven page templates that render `.masthead-right` — `src/dashboards/web/pages/index.html`, `system.html`, `disks.html`, `llm.html`, `ups.html`, `settings.html`, `certs.html` — move the line `<span class="clock" id="clock">--:--:--</span>` from its current position (first control, before the Certs link) to **after** the `<button … id="theme-toggle">` element, so the control row reads `⚷ Certs` → `⚙ Account` → `☾ Dark` → clock. The `<div id="nav-status">` stays the first child (it breaks onto row 2 before the controls). All seven templates must end byte-identical in the control-row region apart from the page-specific comment — `test_every_page_links_to_both_admin_pages` is a one-loop audit precisely because the eight markups are supposed to be the same.
+2. `src/dashboards/web/static/dash.css` — re-word the header comment's row-3 line ("row 3 the `.masthead-right` controls (clock, `⚷ Certs`, `⚙ Account`, theme)") to the new order. No declaration changes.
+3. `tests/test_api.py` — in `test_every_page_links_to_both_admin_pages`: update the docstring's order sentence (clock → Certs → Account → theme toggle ⇒ `⚷ Certs` → `⚙ Account` → theme toggle → clock); keep the two existing `before_theme` assertions (Certs and Account still sit before the theme toggle, Certs before Account — both true in the new order); add the new one: `html.index('id="clock"') > html.index('id="theme-toggle")` on every page (the clock is the last control — on a `flex-end` row that is the farthest-right item). The `/login` half of the test (no links, no toggle) is untouched.
+4. `data/logs/25-task03-verify.cjs` — the browser proof, in the `20-task01-rows.cjs` convention (`NODE_PATH=<playwright node_modules> node data/logs/25-task03-verify.cjs`, `DASH_BASE`/`DASH_PW` env, `check()` accumulator, non-zero exit on any failure): sign in, then on all seven tabbed pages at **1280 px** and **360 px** — (a) group the bar's children into rows by bounding box and assert the three-row shape; (b) the `#nav-status` row and the controls row are flush with the bar's right padding edge (their right edges equal the bar's content right edge within 1 px, and they are **not** flush left — the old layout's right edge was far from the bar's); (c) within the controls row, the clock's right edge is the rightmost of the four controls and the order reads Certs, Account, theme, clock; (d) `#nav-status` on `/certs` and `/settings` is populated (four chips, none `idle`-grey against the live dev fleet — the task 01 check). `/login` (unsigned) at both widths: brand + theme toggle only, no dots, no clock, no horizontal overflow. Screenshots `data/logs/masthead-25-<page>-<width>.png` (the seven tabbed pages at both widths; the script names them, the pass line is every `check()` green).

+- Unit/integration: the extended `test_every_page_links_to_both_admin_pages` (the order pin), with `test_the_masthead_is_three_rows_right_justified_at_every_width` (task 02) and the two task-01 flipped pins as the surrounding contract
+- Coverage: **>90%** on this task's new/modified code (markup + pin + script)

+# Phase 26 — UPS events: power events collapsible, connection errors always visible
+
+**Source:** `TODO.md` L6 — "The phase I ran earlier collapsed all the events in the UPS tab. That wasn't the point. I wanted the power loss events in a collapsible list, not events like \"NUT server NutError: cannot reach upsd at 10.1.0.126:3051 (timed out after 4s)\" in a collapsible list."
+**Story:** n/a
+**Context:** phase 19 (complete) put the **whole** `/ups` event feed behind one collapsed `details.events-box` (no `open` attribute, lazy: `refresh()` fetches the feed only while `state.events.open`, the first expand fetches, a fresh re-expand paints from the `<ul>`'s kept children, `painted`/`fetchedAt` stamped on the success path alone, the `Dash.eventsPager` window of 50 inside the bounded 320px scroll). The operator's complaint is that the classification is wrong, not that a collapse exists: a poll failure like `NUT server NutError: cannot reach upsd … (timed out after 4s)` is hidden behind a summary nobody opens, while the power events it was meant to tuck away are the only ones the operator actually wants collapsed. The feed's **kinds** are fixed and known: the poller (`collectors.py:490` — `Job("nut", "ups", "NUT server", …)`, events under the dashboard name `ups`) writes `unreachable` / `reachable` / `recording` / `store-error` (`poller.py:127/157/164/190` — the quoted `NutError` line is the `unreachable` message); the `NutMonitor` transition bookkeeping writes `status` (a state change lands at `collectors.py:393`) and `test` (the self-test verdict, `collectors.py:409`); `api.py` writes `action` for every command sent through `POST /api/ups/command` (the fixed-text `action` events, `api.py:999/1014`). The served-byte pins for the current shape are in `tests/test_api.py`: `test_ups_power_events_feed_sits_behind_a_collapsed_disclosure` (the `details.events-box`, no `open`, `#events` inside), `test_ups_events_are_fetched_only_while_the_disclosure_is_open` (the lazy gate — **this phase inverts it on purpose**), `test_the_ups_event_rows_keep_the_date_time_and_severity_shape` (the row shape), `test_the_ups_events_disclosure_is_a_quiet_disclosure_not_a_new_component` (the `details.events-box` CSS shape — unchanged by this phase). The page is `src/dashboards/web/static/page-ups.js` (`refresh()` around line 439, `refreshEvents()` around line 445, the disclosure's toggle handler in the `DOMContentLoaded` block) over the card in `src/dashboards/web/pages/ups.html:75-78`.
+
+## Objective
+
+`/ups` renders **two** lists from the one unchanged feed fetch: the power events — state transitions (including the power-loss transitions), self-test verdicts and sent commands — stay behind the collapsed `details.events-box` disclosure, and the connection/error events (`unreachable`/`reachable`/`recording`/`store-error`) are a card that is **always visible** (hidden only while it has no rows to show). The split is page-side, keyed on the event's `kind`; `/api/events` gains no vocabulary.
+
+## Dependencies
+- — (none) — the phase builds on complete phase 19; it is scheduled before `27_mobile_tables_and_audit` on purpose, because that phase's mobile audit captures `/ups` in the shape this phase leaves it in (two cards, one of them hidden-when-empty).
+
+## Tasks
+1. `01_page_side_event_split.md` — the `kind` split in `page-ups.js` (power kinds `status`/`test`/`action`, everything else errors) and the removal of the phase-19 lazy gate: the feed is fetched on every poll, because a visible list that ages is worse than one more 200-event fetch per interval
+2. `02_render_both_lists_paged.md` — the always-visible `#events-errors` card (above the disclosure, hidden while empty) and both lists paged through the shared `Dash.eventsPager`
+3. `03_repin_and_browser_verify.md` — the pin re-pins (the disclosure stays, the lazy gate inverts, the row shape extends to the error list, the kind set is pinned so a silent upstream rename breaks a test) and the phase's real-browser verification
+
+## Testing & Quality
+- Unit/integration: the re-pinned and new pins in `tests/test_api.py` (task 03); the split itself is pinned on the served script (the kind set) and the served markup (the error card, `hidden`, not inside a `<details>`)
+- Coverage: **>90%** on new/modified code
+- Real-browser check (invariant 10): a `data/logs/26-task03-*.cjs` script in the `20-task01-rows.cjs` convention, run against the restarted dev server: the disclosure shut by default, the error card's visibility matching the feed's error-kind rows, both lists' rows matching a direct `/api/events?source=ups&limit=200` split, screenshots in `data/logs/`
+
+## Documentation & Consistency
+
+- The final pass updates the now-stale sentences in `AGENTS.md`: the event-feed paragraph's lazy-fetch block ("`refresh()` fetches the feed only while `state.events.open` is true, so a card nobody is looking at costs the poll loop nothing" and the first-expand/fresh-re-expand sentences) is re-written to the new fact (the one fetch serves two lists, always; the disclosure gates only the power list's visibility), and the pin description of `test_ups_events_are_fetched_only_while_the_disclosure_is_open` is re-pointed at its inverted successor. `README.md` is checked for the same sentence; none is expected.

+# Task 01 — The feed splits on `kind`, and the lazy gate comes out
+
+**Phase:** `26_ups_event_split` · **Source:** `TODO.md:6` — "I wanted the power loss events in a collapsible list, not events like \"NUT server NutError: cannot reach upsd at 10.1.0.126:3051 (timed out after 4s)\" in a collapsible list."
+**Story:** n/a
+
+## Objective
+
+`page-ups.js` splits the one unchanged feed fetch into two lists: the **power** events — `status` (the state transitions, including the power-loss transitions the operator names), `test` (the self-test verdicts) and `action` (the commands sent through the confirm dialog) — and **everything else** (the poller's `unreachable`/`reachable`/`recording`/`store-error`, the quoted `NutError` line included), which is the always-visible error list. The phase-19 lazy gate goes out with the split: a visible list that ages is worse than one more 200-event fetch per interval, so `refresh()` fetches on every poll.
+
+- ASSUMPTION: "power events" is the **known** set of three kinds (`status`/`test`/`action`); any other kind is an error-row by default, because the operator's complaint is that errors must never be the hidden list, and a new kind landing in the hidden list would be the same bug re-shipped.
+
+## Work
+
+1. `src/dashboards/web/static/page-ups.js` — at the top of the file, `const POWER_EVENT_KINDS = new Set(["status", "test", "action"]);` with a comment naming the three writers (`collectors.py:393` `status`, `collectors.py:409` `test`, `api.py` `action` — so a rename on the source side is visible at the site of the drift). In `refreshEvents()`: after the one `fetchJSON(\`/api/events?limit=${Dash.EVENT_FEED_LIMIT}&source=ups\`)` (the call itself is **unchanged** — no `page`/`limit`/`kind` vocabulary, the phase-19 rule), `const power = data.events.filter((e) => POWER_EVENT_KINDS.has(e.kind));` and `const errors = data.events.filter((e) => !POWER_EVENT_KINDS.has(e.kind));`.
+2. `src/dashboards/web/static/page-ups.js` — in `refresh()`, replace `if (state.events.open) await refreshEvents();` with `await refreshEvents();` and re-word the comment above it (the "a shut `<details>` must cost the poll loop nothing" rationale is what the operator overruled: the error list is visible, so the feed is needed whether or not the disclosure is open). In the `DOMContentLoaded` block, delete the `eventsBox` toggle handler's fetch logic — with an always-fresh list the `toggle` event no longer needs to do anything, and `state.events` (with its `open`/`painted`/`fetchedAt` fields) is deleted entirely: the disclosure now gates only the power list's **visibility** (the native `<details>` behaviour), and a failed fetch leaves both lists on their last good rows through `refreshEvents()`'s existing `try { … } catch (err) { /* next poll */ }` — the success-path stamps go away with the state they stamped, and the stale-last-good rule is the `catch` block, which stays.
+3. `src/dashboards/web/static/page-ups.js` — the split is the **only** change to the fetch path: the `row` renderer, `eventText` handling and the `runtime_seconds` footnote stay byte-identical (task 02 points them at both lists), and the `state` object loses `events` with no other field touched.
+
+## Testing & Quality
+- Unit/integration: the split and the gate removal are pinned on the served script in task 03 (`tests/test_api.py`) — the kind set, the unconditional `refreshEvents()` call, the deleted `state.events`
+- Coverage: **>90%** on this task's new/modified code
+- The behavioural proof (a real `unreachable` row visible without opening the disclosure) is the phase's real-browser check (task 03)
+
+## Completion Criteria
+- [ ] `page-ups.js` defines `POWER_EVENT_KINDS = new Set(["status", "test", "action"])` and `refresh()` calls `refreshEvents()` unconditionally (pinned on the served script)
+- [ ] `state.events` and the toggle handler's fetch logic are gone; a failed fetch leaves both lists on their last good rows (pinned where phase 19 pinned its)
+- [ ] the `/api/events` call is byte-identical to the phase-19 one (no new query vocabulary — pinned)
+- [ ] `uv run pytest` green, `ruff` + `pyright` clean
+- [ ] no behavior change in completed work: the poll cadence, the confirm dialog, the hero row and the charts are untouched

+# Task 02 — The error card: always visible, hidden only when empty
+
+**Phase:** `26_ups_event_split` · **Source:** `TODO.md:6` — "I wanted the power loss events in a collapsible list, not events like \"NUT server NutError: cannot reach upsd at 10.1.0.126:3051 (timed out after 4s)\" in a collapsible list."
+**Story:** n/a
+
+## Objective
+
+The error list is a card of its own, **above** the power-events card, built from the existing vocabulary (`section.card`, `ul.events`, the pager's strip) with no new CSS component: visible from first paint while it has rows, `hidden` while it has none, and paged by the same `Dash.eventsPager` the power list uses (its `WeakMap` state is keyed by the `<ul>`, so the two lists page independently — the pager's existing contract).
+
+- ASSUMPTION: the error section sits **above** the Power events disclosure — the visibility complaint is about *seeing* the errors, and the collapsible list keeps its current position in the card stack.
+- ASSUMPTION: the error card is `hidden` while it has zero rows — a permanent empty "Connection & errors" card is the noise the page's empty-state rules exist to avoid, and its first `unreachable` row is what makes it appear.
+
+## Work
+
+1. `src/dashboards/web/pages/ups.html` — above the existing `<section class="card" style="margin-top:.85rem">` (the disclosure card, `ups.html:74-79`), add the error card: `<section class="card" id="ups-errors-card" hidden>` with `<header><h3>Connection &amp; errors</h3><span class="spacer"></span><span class="faint">upsd reachability and this process's own failures</span></header>` and `<div class="body"><ul class="events" id="events-errors"><li class="muted">loading…</li></ul></div>`. The `hidden` attribute is the resting state (before the first successful fetch there are no rows); `style="margin-top:.85rem"` moves to the **error** card's position only in the sense that the disclosure card keeps its existing attribute — a `hidden` card is `display: none`, so the disclosure card's own `margin-top` still gives the gap to whatever is above it when the error card is absent, and no rule is needed for the two-cards case beyond the disclosure card's existing attribute (verify in the browser that the gap is `.85rem` in both states; if the hidden card's own margin would double it, drop the error card's `margin-top` and let the stack's own gap rule do the work — the page's sections carry the shared `.85rem` gap).
+2. `src/dashboards/web/static/page-ups.js` — in `refreshEvents()`, after the split (task 01): render the power list exactly as today — `Dash.eventsPager($('#events'), power, { label: 'Power events', … })` with its existing `empty` sentence and `row` renderer — and the error list — `Dash.eventsPager($('#events-errors'), errors, { label: 'Connection & errors', empty: '<li class="muted" style="grid-template-columns:1fr">No connection errors — upsd is answering and this process is recording.</li>', row: <the same `row` function as the power list, extracted to one const so the two lists cannot drift> })`; then `$('#ups-errors-card').hidden = errors.length === 0;`. The `loading…` seed row in the error card is overwritten on the first successful fetch and never shows, because the card is `hidden` until that fetch lands with rows (a first fetch with zero error rows keeps it hidden — no flash).
+3. `src/dashboards/web/static/dash.css` — **no new rules**: the card, the `ul.events` bounded 320px scroll and the `.events-pager` strip are all existing vocabulary (the phase-19 rule a second opinion about the driver's word is the bug — the same applies to a second style for a second list). If step 1's gap verification needs a rule, the only allowed one is a margin on `#ups-errors-card` itself, pinned in task 03.
+4. The `row` renderer's `runtime_seconds` footnote stays on both lists (an `action` row's runtime is the power list's; an error row simply has no `event.data.runtime_seconds` and prints none — no branch added).
+
+## Testing & Quality
+- Unit/integration: task 03's pins — the error card in the served markup (`hidden`, not inside a `<details>`), the kind set, the single `row` const, the `hidden = errors.length === 0` line
+- Coverage: **>90%** on this task's new/modified code
+- The two-cards layout, the gap in both states and the error card's first-appear are the phase's real-browser check (task 03)
+
+## Completion Criteria
+- [ ] `/ups` shows the `Connection & errors` card above the Power events disclosure, paged, sharing the row shape (pinned + measured in a browser)
+- [ ] the card is `hidden` while the feed has no non-power kinds and appears with its first error row, the gap to the disclosure card being `.85rem` in both states (measured)
+- [ ] both lists page independently (pager state per `<ul>`) and a failed fetch leaves both on their last good rows (pinned)
+- [ ] no new CSS selector is introduced for the error card (pinned)
+- [ ] `uv run pytest` green, `ruff` + `pyright` clean
+- [ ] no behavior change in completed work: the disclosure's CSS shape and the power list's empty sentence are untouched
