phase: 09_wall_remote_page

**Phase 09 — final verification pass (all 3 tasks already in `complete/`; phase work was in the working tree, verified, nothing needed fixing)** **Gates** — `uv run ruff check . && uv run ruff format --check .` → clean; `uv run pyright` → 0 errors; `uv run pytest` → **360 passed, 5 skipped** (only the realdisplay rung), coverage 96% total / 95% app.py; `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (documented host limitation: no audio source on the real X11 path); `uv run pytest tests/e2e/test_remote_control.py` → 8/8 passed; `node --check` on every `static/*.js` → all pass. **Completion criteria** — all met: (1) "Show on wall" stages on the display, asserted on display DOM + `/api/kiosk` ✓; (2) Back/Fullscreen + untouched second controller converge (TestConvergence) ✓; (3) `/api/streams` reports `viewers: 0` / `watching: 0` with only `/remote` open (TestACostsNothing) ✓; (4) followers count displays only — 0/1/1 with a second controller (TestFollowers) ✓; (5) controller works with no display: `followers: 0`, state stored (protocol test + e2e) ✓; (6) e2e + full `-m e2e` + realdisplay all green ✓; (7) README + SECURITY.md updated, Silverblue default now `/kiosk` (installer, conf, gnome script, checker) ✓; (8) suite 100% green, coverage >90% on new code ✓; (9) PLAN.md untouched; AGENTS.md changed only for a stale statement ✓. **Documentation** — README.md reviewed in full against code (page table, quickstart, env-var table vs `config.py`/`debug.py`, presets, keys, deployment, kiosk section): no inconsistencies found. AGENTS.md: fixed the one stale statement introduced by this phase ("Four pages" → "Five pages"); no other staleness, nothing added. **Decisions** — no repo changes were required; the one realdisplay skip is a pre-documented environment fact, not a failure. **Next pending phase** — none; `todo/` held only phase 09.

 # Phase 06 — The sharer picks the quality/CPU trade
 **Source:** chat — "I'm sharing my screen and it's taking a lot of cpu resources. Anything we can
 do about that?" Measured on the reporting machine while it shared: one LibreWolf content process at
 **~105% CPU**, hot threads `WebrtcWorker #105 ×9, #107, #108, #109` — i.e. the *sender-side video
 encoder*, not the page and not the Python server (A3: media never touches the server). The same
 machine drives a 2560×1600 panel and a 3840×2160 primary, so `pickSurface()` asks for ~8.3 Mpx at
 30 fps and phase 02 then told the encoder it may never buy relief with resolution.
 **Story:** n/a
 **Context:** `PLAN.md` §2 A3 (mesh, one `RTCPeerConnection` per viewer → one encode per leg), A9/A10
 (hand-written ES modules, no new assets or dependencies), A12 (env config; this phase adds none),
 §6 ("Mesh upload = N × bitrate per sharer"), §7 item 4 (capacity & fairness — deliberately *not*
 this phase); `AGENTS.md` §5/§6 (media asserted on the viewer, `node --check`, element/id guards);
 `src/mirror/static/share.js` (`pickSurface`, `applySenderQuality`, `addPeer`, `sampleStats`, the
 share-page key router), `src/mirror/static/mirror.html` (the Capture panel), `src/mirror/config.py`
 (`max_bitrate_bps` → `/api/config`), `.agents/phases/complete/02_sharp_capture`
 ## Objective
 `/mirror` grows a **Quality** control — `Sharp · Balanced · Light` — so a sharer can spend pixels,
 frame rate and bitrate for *their* machine instead of inheriting one global server default. Each
 preset maps to a capture pixel budget + frame rate, a per-leg bitrate factor, a `contentHint` and a
 `degradationPreference`, applies live where the engine allows, and is readable in the panel
 alongside the codec actually in use.
 `Sharp` **is** today's behaviour and stays the default, so nothing a completed phase proved gets
 worse; the new presets only ever ask for less.
 ## Dependencies
 - `02_sharp_capture` (complete) — the code this phase parameterises (`pickSurface`'s size request,
  `applySenderQuality`, `sendEncodings`) and the sharpness floor it must not regress:
  `tests/e2e/test_sender_fidelity.py` asserts `degradationPreference === "maintain-resolution"` and
  `maxBitrate == /api/config.maxBitrateBps` on the **default** preset, with two legs.
 - `01_keyboard_kiosk_control` (complete) — the share page's own key router (`s`/`x`/`Esc`), which
  the new `q` joins under the same contract.
 - `05_autohide_stage_controls` (complete) — the current `tests/e2e/` two-context fixture style this
  phase's suite copies.
 ## Tasks
 1. `01_quality_selector_and_preset_table.md` — the `#quality` select in the Capture panel plus the
   `PRESETS` table in `share.js`; no capture or encoder behaviour changes yet
 2. `02_capture_constraints_from_the_preset.md` — `pickSurface()` builds its size/frame-rate request
   (and the track's `contentHint`) from the selected preset
 3. `03_sender_parameters_from_the_preset.md` — per-leg `maxBitrate` factor and
   `degradationPreference` come from the preset, at both call sites
 4. `04_apply_live_and_republish.md` — a preset change while live re-parameterises every existing
   leg and re-applies the capture constraints without a renegotiation; `q` cycles it
 5. `05_quality_and_codec_readout.md` — `#stat-quality` / `#stat-codec` in the panel, fed by the
   existing 1 s stats tick
 6. `06_preset_e2e_suite_and_docs.md` — the full preset matrix in the browser, a `realdisplay`
   delivered-pixels case, and the README/SECURITY consistency pass
 ## Scope boundaries (explicit)
 - **No new environment variable, no new wire field, no Python behaviour change.**
  `MIRROR_MAX_BITRATE` stays the per-leg ceiling and each preset's factor is applied to it, so one
  server knob still governs the fleet. A12/A5/A6 untouched.
 - **No watcher-count fairness.** Dividing the cap by viewer count would change
  `test_two_live_legs_report_maintain_resolution_and_the_cap`, i.e. the behaviour a completed phase
  asserts. That is PLAN §7 item 4 and needs the user's decision first, so it is a separate phase.
 - **No codec preference (`setCodecPreferences`).** Measured on the reporting machine, VA-API on both
  GPUs exposes `AV1Profile0 : VAEntrypointEncSlice` and **no** H.264/HEVC encode entrypoint, and
  Firefox's VA-API encode path is H.264-only — so from LibreWolf there is no hardware encoder to
  prefer. A codec-preference phase needs a measured problem on the Chromium side.
 - **No memory of the choice** (no `localStorage`): a silently persisted `Light` is a worse wall for
  the next person than one extra click.
 - **No change to the default.** Default `sharp` reproduces phase 02 byte for byte.
 ## Testing & Quality
 - Unit/integration: the media behaviour is frontend — per `PLAN.md` §5 it is asserted **in the
  browser**, on the **viewer's** `<video>` (decoded size, frames that differ), never by unit tests
  pretending to be WebRTC. Structure guards live in `tests/test_app.py`: the `$("#id")` existence
  test, the cross-page id-collision test (`{"net","notice","toast"}` only), the
  `test_share_never_asks_for_an_exact_capture_size` guard (presets use `ideal`, never `exact`), and
  one new guard that the option values in `mirror.html` and the keys of `PRESETS` are the same three
  strings (one list, two places, one test that notices — same spirit as the bitrate-default test).
 - 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), including `uv run pytest -m e2e` and
  `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`, plus the other three gates of `AGENTS.md` §4.
 - `tests/e2e/test_sender_fidelity.py` is the regression canary for this phase and must stay green
  **unmodified**.
 ## Documentation & Consistency
 - The final pass reviews `README.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**. For
  `AGENTS.md` it fixes only *stale statements* (a dead command, a changed rule, an outdated fact)
  and **never adds or expands its content** (a file that states its own update policy, e.g. "updated
  rarely, if ever", wins).
 - Tasks update `README.md` immediately when their own changes are user-visible (setup, commands,
  configuration, features, conventions), and `AGENTS.md` only when a statement in it became stale.
 - `SECURITY.md` currently says `MIRROR_MAX_BITRATE` "bounds per-viewer upload"; after task 03 that
  bound is factor-scaled by the sharer's preset. Task 06 makes that sentence true again.
 - `PLAN.md` §6's "per-leg `maxBitrate` cap (default 12 Mbit/s)" is already stale (phase 02 raised the
  default to 25 Mbit/s). This phase must **not** edit `PLAN.md`; report it to the user instead.
 ## Completion Criteria
 - [ ] `/mirror` renders a `#quality` control with exactly `sharp|balanced|light`; `sharp` is the
      selected default and reproduces today's request (3840×2160 cap, `frameRate.ideal 30`) — proven
      by `tests/e2e/test_sender_fidelity.py` passing unmodified
 - [ ] selecting `light` **before** sharing requests ≤ 960×600 at 15 fps (`__probe.lastRequested`),
      sets `contentHint: "motion"`, and every leg commits `maxBitrate == round(cap × 0.35)` with
      `degradationPreference == "maintain-framerate"` — while the viewer still shows ≥2 distinct
      frames
 - [ ] changing the preset **mid-share** re-parameterises the existing legs with no new
      `RTCPeerConnection` (`#viewer-count` and `__probe.peers.size` unchanged) and no renegotiation,
      and the viewer keeps moving
 - [ ] where the engine honours `applyConstraints`, the capture follows without a new picker and
      `/api/streams` width/height match the sharer's `track.getSettings()` (the republish happened);
      where it does not, the panel toasts that the change lands on the next share — no silent lie
 - [ ] `q` cycles the preset on the share page and toasts the new one; keys typed in `#name` and the
      select remain text, not commands
 - [ ] `#stat-quality` shows the effective budget and `#stat-codec` shows the negotiated codec, or `—`
      where the engine does not report it; both reset to `—` when idle
 - [ ] `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` proves delivered pixels follow the preset:
      `light` decodes at or under its cap, `sharp` still clears `SHARP_FLOOR_PX`
 - [ ] no new env var, no new wire field, no Python behaviour change, no external asset, no framework
 - [ ] full test suite **100% passing** (every test in the project, not just this phase's), coverage >90%
 - [ ] README.md is accurate and consistent with the whole project; AGENTS.md has no stale statements
      (verified in the final pass); `PLAN.md` untouched, its stale 12 Mbit/s figure reported to the user
 - [ ] no behavior change in completed phases

 # Task 01 — The Quality control and the preset table
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 Put a `#quality` select in the share panel and the `PRESETS` table in `share.js`, wired so that the
 default (`sharp`) is provably today's behaviour. **No capture or encoder behaviour changes in this
 task** — later tasks read the table.
 ## Work
 1. `src/mirror/static/mirror.html` — inside `<aside class="panel">`, directly under
   `<h2>Capture</h2>` and **before** `<dl class="stats">`, add the control. Keep the `<label>`-wraps-
   control shape used by `#name` so it inherits the panel's field styling:
   ```html
   <label>
     Quality
     <select id="quality" autocomplete="off">
       <option value="sharp" selected>Sharp — every pixel, most CPU</option>
       <option value="balanced">Balanced — 1080p-class, less CPU</option>
       <option value="light">Light — small and cheap</option>
     </select>
   </label>
   ```
   `quality` is a new id on `mirror.html` only — the cross-page test
   (`test_the_two_pages_share_no_element_ids_but_the_shared_chrome`) allows exactly
   `{"net","notice","toast"}` to be shared, so do **not** add it to `watch.html` or `index.html`.
 2. `src/mirror/static/app.css` — extend the existing field rule at L339
   `.panel input[type="text"] { … }` to `.panel input[type="text"], .panel select { … }` so the
   select gets the same chrome. Do not add a `display` declaration anywhere and do not touch
   `dl.stats`, `.panel label` or `[hidden]` — `TestStylesheet` guards those.
 3. `src/mirror/static/share.js` — add `quality: $("#quality"),` to the `ui` map (the element test
   `test_every_element_the_script_reaches_for_exists` requires the id from step 1 to exist).
 4. `src/mirror/static/share.js` — add the preset table at module scope, next to `surfaceName()`,
   exactly these three keys and numbers. The table is the whole product decision, so every field is
   commented with what it buys:
   ```js
   /* The sharer's side of the CPU/cpu-sharpness trade (phase 06): the encoder on a software-only
    * machine is ~1 core at 4K30, and `MIRROR_MAX_BITRATE` alone cannot express "fewer pixels".
    * Each preset is one request to the capture device and one per-leg encoder budget.
    *
    * - `max`           pixel ceiling for the size request, still `ideal` (never `exact` —
    *                   `test_share_never_asks_for_an_exact_capture_size`); the request is
    *                   min(screen × devicePixelRatio, max).
    * - `frameRate`     the capture's frame-rate request; a static page of text needs far less
    *                   than 30 and every frame costs an encode.
    * - `bitrateFactor` multiplied into `config.maxBitrateBps` — the server keeps the ceiling, the
    *                   sharer picks the fraction of it (A12: one knob, no new env var).
    * - `contentHint`   `detail` for text, `motion` where smoothness is the point.
    * - `degradation`   what the encoder may sacrifice under pressure. Firefox rejects
    *                   `degradationPreference` outright; applySenderQuality's named
    *                   NotAllowedError catch already covers that. */
   const PRESETS = Object.freeze({
     sharp: {
       max: [3840, 2160],
       frameRate: { ideal: 30, max: 60 },
       bitrateFactor: 1,
       contentHint: "detail",
       degradation: "maintain-resolution",
     },
     balanced: {
       max: [1920, 1200],
       frameRate: { ideal: 24, max: 60 },
       bitrateFactor: 0.6,
       contentHint: "detail",
       degradation: "balanced",
     },
     light: {
       max: [960, 600],
       frameRate: { ideal: 15, max: 30 },
       bitrateFactor: 0.35,
       contentHint: "motion",
       degradation: "maintain-framerate",
     },
   });
   const DEFAULT_PRESET = "sharp";
   /** The preset the control selects; an unknown or absent value falls back to `sharp`, which is
    *  today's behaviour, so a missing element or a stale value can never degrade the wall. */
   function currentPreset() {
     const key = ui.quality && ui.quality.value;
     return PRESETS[key] ? key : DEFAULT_PRESET;
   }
   ```
   `sharp`'s numbers are today's hardcoded values verbatim — that is the no-regression argument, and
   tasks 02/03 replace the literals with reads from this table.
 5. Do **not** touch `pickSurface()`, `applySenderQuality()`, `addPeer()` or the stats tick yet.
 6. `README.md` — under the `/mirror` usage section, add a short paragraph: the share page has a
   Quality control (`Sharp` default = every pixel; `Balanced`; `Light`), it trades capture size,
   frame rate and per-viewer bitrate, and it is per sharer. Task 06 writes the full table; here, one
   accurate paragraph is enough.
 ## Testing & Quality
 - Unit/integration: add to `tests/test_app.py::TestClientScripts` a
  `test_the_quality_options_are_the_three_presets` guard — the `value="…"` set of `#quality` in
  `mirror.html` and the keys of `PRESETS` in `share.js` must be exactly
  `{"sharp","balanced","light"}` (regex over both files; same "one number, two places, one test that
  notices" shape as `test_server_and_client_agree_on_the_bitrate_default`).
 - The existing guards must stay green unchanged: `test_scripts_parse_as_es_modules`
  (`node --check`), `test_every_element_the_script_reaches_for_exists`,
  `test_the_two_pages_share_no_element_ids_but_the_shared_chrome`,
  `test_share_never_asks_for_an_exact_capture_size`, `TestStylesheet`.
 - Coverage: **>90%** on this task's new/modified code — `currentPreset()` and the control are
  exercised from the browser in task 02's suite; a structure guard covers the option/key agreement.
 ## Completion Criteria
 - [ ] `/mirror` shows the Quality select under "Capture", with `Sharp` selected and the three options above
 - [ ] `uv run pytest tests/test_app.py` green, including the new three-preset agreement guard
 - [ ] the select inherits the panel's field styling (same background/border/radius as `#name`), no new `display` rule
 - [ ] pressing `Tab` into the select and using the arrow keys does not trigger the page's `s`/`x` shortcuts (the router's existing `HTMLSelectElement` guard)
 - [ ] capture and encoder behaviour are byte-for-byte what they were before this task
 - [ ] full test suite **100% passing** (every test in the project, not just this task's)
 - [ ] README.md updated for anything user-visible this task changes; AGENTS.md touched only if a statement in it became stale (the phase's final pass re-checks both)

 # Task 02 — The capture request comes from the preset
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 `pickSurface()` asks the capture device for the *selected* preset's pixels and frame rate instead of
 the hardcoded 4K/30, and the track's `contentHint` follows the preset. `sharp` must produce exactly
 the request it produces today.
 ## Work
 1. `src/mirror/static/share.js` — extract the constraint builder from `pickSurface()` into a pure
   helper (task 04 needs the identical numbers for `applyConstraints`):
   ```js
   /** The size/frame-rate request for a preset, plus the size we asked for (the panel's shortfall
    *  toast compares the delivered width against it). `ideal`, never `exact` — a hard size fails or
    *  hides picker entries on displays/DPRs the browser cannot honour (AGENTS.md §5). */
   function presetCapture(preset) {
     const dpr = window.devicePixelRatio || 1;
     const [maxW, maxH] = preset.max;
     const requested = {
       width: Math.min(Math.round(screen.width * dpr), maxW),
       height: Math.min(Math.round(screen.height * dpr), maxH),
     };
     return {
       requested,
       video: {
         width: { ideal: requested.width },
         height: { ideal: requested.height },
         frameRate: { ...preset.frameRate },
       },
     };
   }
   ```
 2. `pickSurface()` — take the key **once** at the top
   (`const key = currentPreset(); const preset = PRESETS[key];` and build `shared` from
   `presetCapture(preset).video`) so the audio attempt and its silent retry keep sending *identical*
   video constraints (the existing comment about one shared `video` object still holds — preserve it).
   Return `key` alongside `requested` so `start()` records which preset the live capture belongs to.
 3. `start()` — set `state.qualityKey = captured.key;` (initialise `qualityKey: DEFAULT_PRESET` in
   `state`), and replace `video.contentHint = "detail";` with
   `video.contentHint = PRESETS[state.qualityKey].contentHint;`, keeping the comment's reasoning and
   adding one line: the hint is per-preset now — `Light` is glanceable content, so motion wins over
   glyph crispness.
 4. Leave the 75%-shortfall toast comparing `delivered.width` with `state.requested.width` — it is now
   preset-relative, which is what makes it still true for `Light`.
 5. `window.__probe` — add two read-only getters (this stays *the one global*, AGENTS.md §6):
   `get lastRequested() { return state.requested; }` and
   `get qualityKey() { return state.qualityKey; }`. Tests assert the request; delivered pixels are
   asserted in task 06 on a real desktop.
 6. `tests/e2e/test_quality_presets.py` — new suite, `pytestmark = [pytest.mark.e2e,
   pytest.mark.timeout(180)]`, with the `device()` fixture copied from
   `tests/e2e/test_sender_fidelity.py` (one copy per suite is the convention here) and the first
   case: `test_each_preset_asks_the_capture_for_its_own_budget`. For each of `sharp|balanced|light`:
   fresh page, `select_option("#quality", key)`, `start_sharing(page)`, then read
   `__probe.lastRequested` and `__probe.qualityKey` and assert
   `width == min(round(screen.width * devicePixelRatio), cap_w)` (read `screen.width` /
   `devicePixelRatio` from the page — under Playwright `screen` is the emulated viewport, so
   hardcoding a display size would make this environment-dependent).
   **Do not assert delivered pixels in this suite**: with
   `--use-fake-device-for-media-stream` the synthetic device is 1280×720 and its clamping is not the
   behaviour under test (`PLAN.md` §5). Task 06 asserts delivered pixels where a real capturer runs.
 ## Testing & Quality
 - Unit/integration: the new suite above; `test_share_never_asks_for_an_exact_capture_size` must stay
  green (the builder uses `ideal` only); `tests/e2e/test_live_mirror.py` and
  `tests/e2e/test_sender_fidelity.py` (default `sharp`) must pass untouched.
 - Coverage: **>90%** on this task's new/modified code.
 ## Completion Criteria
 - [ ] with `sharp` selected, the request is still `min(screen × dpr, 3840×2160)` at `frameRate {ideal: 30, max: 60}` (asserted, and `test_sender_fidelity.py` green unmodified)
 - [ ] with `light` selected before sharing, `__probe.lastRequested` is capped at 960×600 and `__probe.qualityKey == "light"`
 - [ ] the shared track's `contentHint` is `detail` for sharp/balanced and `motion` for light
 - [ ] the audio attempt and its silent retry still pass byte-identical video constraints
 - [ ] full test suite **100% passing** (every test in the project, not just this task's)
 - [ ] README.md updated for anything user-visible this task changes; AGENTS.md touched only if a statement in it became stale (the phase's final pass re-checks both)
 - [ ] no behavior change in completed work

 # Task 03 — Per-leg bitrate and degradation come from the preset
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 Each leg encodes under the selected preset's share of `MIRROR_MAX_BITRATE` and the preset's
 `degradationPreference`, at both places that set encoder parameters. `sharp` keeps the exact
 25 Mbit/s / `maintain-resolution` behaviour phase 02 asserted.
 ## Work
 1. `src/mirror/static/share.js` — add one helper next to `PRESETS` so the two call sites cannot
   drift:
   ```js
   /** The per-leg bitrate cap for the preset in force: the server's ceiling
    *  (`config.maxBitrateBps`, from MIRROR_MAX_BITRATE) scaled by the preset's factor. 0 stays 0 —
    *  "uncapped" is a real setting in the WebRTC API and must not become a 0 bps leg. */
   function legCap() {
     const cap = config.maxBitrateBps || 0;
     return cap ? Math.round(cap * PRESETS[currentPreset()].bitrateFactor) : 0;
   }
   ```
 2. `applySenderQuality()` — replace the two hardcoded pieces:
   - `params.degradationPreference = PRESETS[currentPreset()].degradation;`
   - `if (legCap()) params.encodings[0].maxBitrate = legCap();`
   Keep the truthy-cap rule (0 = uncapped), the first-encoding-only rule (the cap is per leg, not
   per simulcast layer), the named `NotAllowedError` catch, and the re-apply call sites
   (post-`setLocalDescription` and on `connected`) exactly as they are — that is what keeps the cap
   across every renegotiation, and it must re-read the *current* preset, which is why this reads
   `currentPreset()` at call time rather than a value captured at module load.
 3. `addPeer()` — `const cap = legCap();` before the track loop, then
   `if (track.kind === "video" && cap) init.sendEncodings = [{ maxBitrate: cap }];`, keeping the
   comment that explains why `sendEncodings` is kept *in addition to* the post-negotiation re-apply
   (it is the only thing capping the leg between `addTransceiver` and the first
   `setLocalDescription`).
 4. Do not add a renegotiation anywhere: neither parameter needs a new offer (A4 — the sharer offers
   when the *track set* changes).
 ## Testing & Quality
 - Unit/integration: extend `tests/e2e/test_quality_presets.py` with
  `test_a_light_leg_encodes_at_the_presets_share` — sharer selects `light`, one viewer goes live,
  then read the committed parameters back through `window.__probe.peers` (the `SENDER_PROBE` shape
  from `tests/e2e/test_sender_fidelity.py`, copied per suite convention) and assert
  `maxBitrate == round(cap × 0.35)` and `degradationPreference == "maintain-framerate"`, where `cap`
  is read live from `/api/config` (never hardcoded). Assert the wall is still moving
  (`frames_matching(...)["distinct"] >= 2`) — a cheaper picture must not be a dead one — and
  `errors == []`.
 - Regression: `tests/e2e/test_sender_fidelity.py` must pass **unmodified** — it asserts
  `maxBitrate == /api/config.maxBitrateBps` and `maintain-resolution` on two legs with the default
  preset, which is precisely this task's no-change guarantee.
 - Coverage: **>90%** on this task's new/modified code.
 ## Completion Criteria
 - [ ] `light` yields `maxBitrate == round(maxBitrateBps × 0.35)` and `maintain-framerate` on a live leg (asserted)
 - [ ] `sharp` still yields the full `/api/config` cap and `maintain-resolution` (existing suite, unmodified)

 # Task 04 — Changing quality mid-share, without dropping a viewer
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 A preset change takes effect on the share that is already running: every existing leg is
 re-parameterised immediately, the capture follows where the engine honours `applyConstraints`, and
 the panel says plainly when it cannot. No renegotiation, no new peer connection, no second picker.
 ## Work
 1. `src/mirror/static/share.js` — add `applyQuality()` after `applySenderQuality()`:
   - `const key = currentPreset(); const preset = PRESETS[key]; state.qualityKey = key;`
   - **Legs first** (these commit without an offer, so the CPU/egress change is instant):
     `for (const peer of state.peers.values()) await applySenderQuality(peer).catch(err => console.warn("sender quality", err));`
   - No live video track → return after the legs (the choice is simply picked up by the next
     `start()`).
   - `track.contentHint = preset.contentHint;` then, only when
     `typeof track.applyConstraints === "function"`:
     `await track.applyConstraints(presetCapture(preset).video)`; on **`OverconstrainedError`**
     retry with the frame rate alone — `await track.applyConstraints({ frameRate: preset.frameRate })`
     — because a display that cannot rescale can still change rate. Swallow only what is named
     (`AGENTS.md` §7): any other error means the capture keeps its current size.
   - On a constraint success: `state.requested = presetCapture(preset).requested;` then `publish()`
     so the roster's `width`/`height` — and every wall tile's caption — match the capture rather than
     the last share. On failure: do **not** republish; the track did not change.
   - Toast the outcome in one line, naming the preset, its budget and whether the capture followed,
     e.g. `` `Balanced · ≤${maxW}×${maxH} @${fps}fps · ${bitrateFormat(legCap())} per viewer` `` and
     `` `… · capture size applies next share` `` when `applyConstraints` failed. `bitrateFormat`
     already renders `—` for a 0/uncapped cap, so say "uncapped" instead when `legCap()` is 0.
   - Never call `negotiate()` here, and never touch `srcObject`: the track object is unchanged, the
     transceiver keeps it (AGENTS.md §6 — move the element, not the stream; A4 — the sharer offers
     when the *track set* changes, which this does not).
 2. Wire it: `ui.quality.addEventListener("change", () => { applyQuality().catch(err => console.warn("quality", err)); });`
   (the page is already all-`await` at module scope; keep the handler non-async so a rejected
   constraint never becomes an unhandled rejection — the E2E suites fail on any `pageerror`).
 3. `src/mirror/static/share.js` — the share page's key router: add a `q` branch after `x`, under the
   router's existing rules (chords with Ctrl/Cmd/Alt belong to the browser; a key in `#name` or the
   select is text). It cycles `sharp → balanced → light → sharp` over `Object.keys(PRESETS)`,
   sets `ui.quality.value = next`, calls `await applyQuality()`, and `preventDefault()`s. When
   `state.picking` is true it must **toast** (`a picker is already up`) rather than silently no-op —
   a keyboard-only operator cannot debug silence, which is the rule already written above the router.
 4. `README.md` — extend task 01's paragraph: changing Quality applies to the running share (bitrate
   and frame rate always, capture size where the browser allows), and `q` cycles it.
 ## Testing & Quality
 - Unit/integration: extend `tests/e2e/test_quality_presets.py` with
  `test_changing_quality_mid_share_re_prices_the_live_leg`:
  sharer starts on the default, one viewer goes live, then `select_option("#quality", "light")`.
  Assert — through `__probe` — that the peer count is still **1** (no new `RTCPeerConnection`), that
  the same leg's committed `maxBitrate` becomes `round(cap × 0.35)` within ~5 s, that
  `connectionState` returns to / stays `connected`, and that the viewer's `<video>` still shows
  `distinct >= 2` frames (the switch did not freeze anybody). Then assert the roster tells the truth:
  `GET /api/streams` width/height equal the sharer's `track.getSettings()` — whatever the engine
  settled on, the two must agree (do **not** assert a specific delivered size here; the synthetic
  device clamps, and task 06 owns delivered pixels).
  Plus `test_q_cycles_the_preset_and_says_so`: `keyboard.press("q")` advances `#stat`/`#quality`
  value and the toast text names the preset; a `q` typed into `#name` never changes the select.
 - Coverage: **>90%** on this task's new/modified code.
 ## Completion Criteria
 - [ ] selecting `light` while sharing changes the live leg's committed `maxBitrate` (asserted) without creating a second `RTCPeerConnection` and without a renegotiation
 - [ ] the viewer keeps decoding moving frames across the switch (`distinct >= 2`)
 - [ ] `/api/streams` width/height agree with the sharer's `track.getSettings()` after the switch, in both the honoured and the refused-`applyConstraints` cases
 - [ ] a toast always names the resulting preset and budget, and adds "capture size applies next share" when the engine refused to rescale
 - [ ] `q` cycles the preset and toasts; keys in `#name` and in the select stay text; `s`/`x`/`Esc` behave as before
 - [ ] no `pageerror` in any suite (`errors == []`)
 - [ ] full test suite **100% passing** (every test in the project, not just this task's)
 - [ ] README.md updated for anything user-visible this task changes; AGENTS.md touched only if a statement in it became stale (the phase's final pass re-checks both)

 # Task 05 — Show what the share is actually costing
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 Two new lines in the share panel — the quality budget in force, and the codec the legs actually
 negotiated — so the next "why is my fan spinning" starts with a readout instead of a profiler.
 ## Work
 1. `src/mirror/static/mirror.html` — in `<dl class="stats">`, add after `<dt>Resolution</dt>`:
   ```html
   <dt>Quality</dt>
   <dd id="stat-quality">—</dd>
   <dt>Codec</dt>
   <dd id="stat-codec">—</dd>
   ```
   New ids on this page only (`stat-quality`, `stat-codec`) — the cross-page id test allows only
   `net`/`notice`/`toast` to be shared.
 2. `src/mirror/static/share.js` — add `qualityStat: $("#stat-quality")` and `codec: $("#stat-codec")`
   to `ui`; set both to `"—"` in `renderIdle()`.
 3. `src/mirror/static/share.js` — one `renderQuality()` that writes the preset line from state, and
   call it from `start()`, from `applyQuality()` (task 04) and from `renderIdle()`:
   `` `${key} · ≤${maxW}×${maxH} @${preset.frameRate.ideal}fps · ${legCap() ? bitrateFormat(legCap()) + " /viewer" : "uncapped /viewer"}` ``
   Keep it one line; `dl.stats dd` already wraps with `overflow-wrap: anywhere`.
 4. `sampleStats()` — inside the existing per-pc report loop (no new timer, no extra `getStats()`
   call), when it sees the video `outbound-rtp` entry, also resolve its codec:
   `const codecEntry = entry.codecId ? report.get(entry.codecId) : null;` and take
   `entry.codec || codecEntry?.mimeType || codecEntry?.codec || ""`, then render the short form
   (`"video/VP8"` → `VP8`). Write it to `#stat-codec` once per tick:
   - a resolved name when any leg reported one,
   - `"—"` when none did, with a comment stating why: Firefox does not expose the outbound codec in
     `getStats()` for every leg, and the panel must not guess.
   Do **not** present this as a hardware/software indicator — the encoder's implementation is not
   exposed to the page; the codec name is the honest floor of what can be said.
 5. `README.md` — one sentence in the `/mirror` section: the panel shows the quality budget in force
   and the negotiated codec (`—` where a browser does not report it).
 ## Testing & Quality
 - Unit/integration: `test_every_element_the_script_reaches_for_exists` must pass with the two new ids
  (the elements exist in `mirror.html`); extend `tests/e2e/test_quality_presets.py` with
  `test_the_panel_shows_the_budget_and_the_codec` — after a live leg with `#quality = balanced`,
  `#stat-quality` text contains `balanced` and `1920`, and `#stat-codec` is either `—` or a short
  codec name matching `^[A-Z0-9/]{2,16}$` (assert the *shape*, not a specific codec — the codec the
  engine picks is not a contract); after Stop sharing, both return to `—`.
 - Coverage: **>90%** on this task's new/modified code.
 ## Completion Criteria
 - [ ] while live, `#stat-quality` reads like `balanced · ≤1920×1200 @24fps · 15.0 Mbps /viewer` (asserted)
 - [ ] `#stat-codec` shows the negotiated codec name when the engine reports one and `—` when it does not; it never shows a guess
 - [ ] both lines reset to `—` when the share stops (`renderIdle`)
 - [ ] no additional `getStats()` call and no new interval were introduced
 - [ ] full test suite **100% passing** (every test in the project, not just this task's)
 - [ ] README.md updated for anything user-visible this task changes; AGENTS.md touched only if a statement in it became stale (the phase's final pass re-checks both)

 # Task 06 — The preset matrix in the browser, on a real desktop, and in the docs
 **Phase:** `06_sharer_quality_presets` · **Story:** n/a
 ## Objective
 Close the phase: the full preset matrix asserted in the browser, one `realdisplay` case proving
 delivered **pixels** follow the preset, and the documentation pass that makes `README.md` and
 `SECURITY.md` true again.
 ## Work
 1. `tests/e2e/test_quality_presets.py` — finish the suite the earlier tasks started, so it covers
   every claim in `00_phase.md`:
   - all three presets request their own budget (task 02's case) — `sharp` first, so the
     no-regression request is the first thing the file proves;
   - per-preset committed sender parameters: `sharp` → full cap + `maintain-resolution`;
     `balanced` → `round(cap × 0.6)` + `balanced`; `light` → `round(cap × 0.35)` +
     `maintain-framerate`; each with the viewer's frames still moving (`distinct >= 2`);
   - the mid-share switch and the `q` cycle (task 04's cases);
   - the readout (task 05's case);
   - **a second viewer that joins after a switch** inherits the new cap on its first offer (the
     `sendEncodings` path in `addPeer`, not just the re-apply path);
   - every case asserts `errors == []` (no `pageerror`, no `console.error`).
   Read the cap from `GET /api/config` in the test; never hardcode 25 Mbit/s.
 2. `tests/e2e/test_x11_capture.py` — add one `realdisplay`-marked case, reusing that file's existing
   harness (`browser_env()`, `REAL_CAPTURE_ARGS`, `XVFB_GEOMETRY`, the private-Xvfb fixtures). It must
   select `#quality = light` **before** clicking `#start` on its own share page, and assert on the
   **viewer's** `<video>` (`PLAN.md` §5):
   - decoded width `<= 990` and `>= 0.8 × 960` — i.e. the request reached the real capturer rather
     than being clamped away (under Playwright `screen` is the emulated viewport, so `min(viewport,
     960)` is the 960 request);
   - the existing aspect guard (`abs(w/h − XVFB_ASPECT) < 0.06`) still holds — a smaller picture must
     still be *our* desktop, not somebody else's window;
   - `distinct >= 2`, with the same background-cycling that drives motion in
     `test_sharp_picture_reaches_the_wall`;
   - do **not** re-assert the `SHARP_FLOOR_PX` floor here — that test stays as the sharp-path guard,
     and this file must keep distinguishing real capture from the fake device.
   Add a one-line comment recording the measured numbers you saw on this host, the way the phase 02
   test records its 1200×750.
 3. `README.md` — the full pass, in full:
   - a **Quality** table in the `/mirror` section: preset · requested pixel cap · frame rate ·
     per-viewer bitrate as a fraction of `MIRROR_MAX_BITRATE` · `degradationPreference` (what the
     encoder may sacrifice) — and the sentence that `MIRROR_MAX_BITRATE` remains the ceiling the
     factor is applied to, so a Wi-Fi sharer picks `Light` in the page while an operator lowers the
     ceiling for everyone;
   - state that `Sharp` is the default and is what phase 02 shipped;
   - document `q` in the share-page keyboard list;
   - say who this is for: a software-encoding sharer (a Firefox/Linux sharer has no hardware
     encoder on many machines — VA-API exposes no H.264 encode there) burning ~a core at 4K30;
   - re-read the **whole** file against the code as it now stands and fix every inconsistency,
     including pre-existing ones (the phase brief requires it).
 4. `SECURITY.md` — the sentences that say `MIRROR_MAX_BITRATE` "bounds per-viewer upload" / is what
   bounds a viewer's consumption are now only half true: the sharer's preset scales that bound down.
   Make them accurate (a preset can only ever lower the cap, never raise it above the server's), and
   confirm nothing else in the threat model shifted — this phase adds no new capability, so no new
   risk.
 5. `AGENTS.md` — stale statements only, never additions: check §10's quick reference and §3's table
   for anything this phase made untrue (the bitrate row still reads "Per-leg `maxBitrate` cap", which
   is still correct). Do not add a section about presets.
 6. `PLAN.md` — **do not edit**. Its §6 line still says "per-leg `maxBitrate` cap (default 12 Mbit/s)"
   while the code has defaulted to 25 Mbit/s since phase 02; report it to the user in the phase
   summary as a one-line amendment for them to approve.
 ## Testing & Quality
 - Unit/integration: this task adds the phase's browser proof (fake-device matrix + a real-desktop
  delivered-pixels case). Run, in order:
  `uv run pytest -m "not e2e"`, `uv run pytest -m e2e`, then
  `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`.
 - Coverage: **>90%** on the phase's new/modified code.
 ## Completion Criteria
 - [ ] `tests/e2e/test_quality_presets.py` covers all three presets' requests, all three presets' committed sender parameters, the mid-share switch, the `q` cycle, the readout, and a late-joining viewer after a switch — all green, `errors == []`
 - [ ] `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` proves a `light` share decodes on the viewer at or under 990 px wide with moving frames and the desktop's aspect ratio

 # Phase 07 — Shared presentation state on the server
 **Source:** `TODO.md` L3 — "Add a /kiosk endpoint that is controllable by other clients… There should be a /kiosk endpoint which stores 'state' (fullscreen, which mirror is being viewed) that any client can manipulate and will update immediately…" (the server half of that item)
 **Story:** n/a
 **Context:** `.agents/PLAN.md` §2 A5 (one WebSocket, JSON, verb in / noun out), A6 (camelCase on the wire), A7 (in-memory state only — no database, no persistence), A8 (`Registry` stays pure and returns `list[Envelope]`), A11/A19 (no accounts; the address is the gate); `src/mirror/protocol.py`, `src/mirror/registry.py`, `src/mirror/app.py`; `tests/test_registry.py`, `tests/test_protocol.py`, `tests/test_app.py`
 ## Objective
 Give the server one piece of presentation state — **which mirror is on stage, and
 whether it should be fullscreen** — that any connected peer may change and that is
 pushed to everyone the moment it changes. This is the piece the TODO item is
 actually short of: `/watch` already stages and fullscreens locally (phase 01), but
 that decision lives in one tab and dies there, so an unattended display can never
 be driven from elsewhere.
 This phase is **server-side only**: no new page, no browser-visible behaviour yet.
 It leaves the app exactly as usable as it was, with a wire format and a
 `GET /api/kiosk` read surface that phases 08 and 09 build their clients on.
 ## The contract this phase fixes (phases 08/09 code against it verbatim)
 Inbound — verb, like `publish`/`subscribe` (PLAN A5), from **any** peer:
 ```json
 {"type":"arrange","staged":"p1ab2c3d","fullscreen":true}
 ```
 * `staged`: a stream id, or `null` for "back to the wall", or **absent** for "no
  opinion". Absent and explicit-`null` are different requests, which is why the
  model is read with pydantic's `model_fields_set` rather than with defaults.
 * `fullscreen`: `bool`, absent = no opinion.
 * A `staged` value that does not name a live mirror is refused with the existing
  `unknown_stream` error and changes nothing.
 * No audio/mute field. `SECURITY.md` §4: sound must trace back to a gesture on the
  device that plays it — a remote hand cannot unmute a stranger's display.
 Outbound — noun, to every viewer and back to the sender:
 ```json
 {"type":"layout","staged":"p1ab2c3d","fullscreen":true,"followers":1}
 ```
 * `followers` is how many connected peers announced `hello{"kiosk":true}`, i.e.
  how many displays are obeying this. A controller is a plain viewer and is not
  counted, which is what makes "nobody is showing a wall" distinguishable from
  "the wall will follow".
 * Emitted on: any accepted change, a kiosk display joining or leaving, and the
  stale fallback when the staged mirror disappears.
 * `welcome` carries the same object as its `layout` field, so a page is arranged
  before it has asked for anything — the TODO's "navigate to it and it arranges
  itself" depends on this.
 `GET /api/kiosk` answers the same object, so the state is debuggable with `curl`
 exactly like `/api/streams` (AGENTS.md §8).
 ## What is deliberately *not* here
 * **No third role.** `Role` stays `sharer | viewer`; a kiosk is a viewer that
  happens to obey the layout. The signal-authorisation matrix and A4 are
  untouched.
 * **No media coupling.** Staging never subscribes, never negotiates, never touches
  an `RTCPeerConnection` — the kiosk already subscribes to every mirror it can
  show, so "which one is on stage" is pure presentation.
 * **One state per server process.** Not per display, not per room. Two `/kiosk`
  pages follow the same state; that is the product's single-wall model (A7).
 * **No persistence.** Restart the server and the wall is a wall. Consistent with
  A7's reasoning: state that outlives the peers is a lie.
 * **No auto-stage-newest.** The state says what is on stage; nothing here invents
  a value. (`PLAN.md` §7 item 2, "Wall UX", is where auto-stage belongs.)
 ## Dependencies
 - `06_sharer_quality_presets` (complete) — the current wall/stage/keyboard
  behaviour and the green four-gate baseline this phase must not disturb.
  (`.agents/phases/todo/` is empty, so this is the phase directly before 07.)
 ## Tasks
 1. `01_arrange_and_layout_frames.md` — the two message shapes in `protocol.py`
   (`Arrange` inbound, `layout()` outbound builder) plus the `kiosk` flag on
   `hello`, with parse/round-trip tests.
 2. `02_registry_layout_policy.md` — `Layout` state, `Registry.set_layout()` and
   `Registry.layout_dto()`, the fan-out set, the follower count, and the
   stale-staged fallback on teardown; unit-tested with no I/O.
 3. `03_dispatch_read_endpoint_and_wire_tests.md` — `Hub._dispatch` handles
   `arrange`, `GET /api/kiosk` serves the state, and the whole path is covered
   over a real `TestClient` WebSocket.
 ## Testing & Quality
 - **Unit (`tests/test_registry.py`)** owns the policy: partial update vs explicit
  clear, refusal of an unknown stream, fan-out to viewers plus the sender,
  follower counting, the fallback when the staged mirror goes away, and `welcome`
  carrying the state.
 - **Wire (`tests/test_app.py`, `tests/test_protocol.py`)** owns the camelCase
  round-trip and the socket semantics: an `arrange` frame from a sharer, from a
  viewer, with a bad stream id (error frame, socket stays open), and the shape +
  `no-store` of `/api/kiosk` behind the address gate.
 - Coverage: **>90%** on new/modified code (the project sits ~95%; `registry.py` is
  the product and must stay near 100%).
 - All four gates from `AGENTS.md` §4, including `-m e2e` and the `realdisplay`
  suite: this phase changes frames every browser test consumes, so "nothing in the
  browser changed" is itself the assertion.
 ## Completion Criteria
 - [ ] `uv run pytest tests/test_registry.py tests/test_protocol.py tests/test_app.py` green, including the new layout cases
 - [ ] `curl -s localhost:8055/api/kiosk | python -m json.tool` answers `{"staged": null, "fullscreen": false, "followers": 0}` on an idle server, and reflects an `arrange` frame sent with `websocat`

 - [ ] the staged mirror going away (unpublish, disconnect, eviction) resets `staged` to `null` and pushes one `layout` frame — never a stale id
 - [ ] no page, no stylesheet and no browser test changed behaviour (`uv run pytest -m e2e` green with the existing assertions untouched)
 - [ ] full test suite **100% passing**, coverage >90% on new code
 - [ ] `PLAN.md` untouched (no anchor moved: A5/A7/A8/A11 all hold, see above)

 # Task 01 — The `arrange` / `layout` frames
 **Phase:** `07_kiosk_layout_state` · **Source:** `TODO.md:3` — "There should be a /kiosk endpoint which stores 'state' (fullscreen, which mirror is being viewed) that any client can manipulate and will update immediately"
 **Story:** n/a
 ## Objective
 Put both halves of the presentation-state message on the wire: an inbound
 `arrange` verb, an outbound `layout` noun, and a `kiosk` flag on `hello` so the
 server can tell a display from a controller. No behaviour yet — `Registry` is
 wired in task 02, the socket in task 03.
 ## Work
 1. `src/mirror/protocol.py` — add the inbound verb after `Subscribe`/`Unsubscribe`,
   in the `_Inbound` house style. Both fields are `| None` **and** optional, because
   "leave what I did not mention alone" and "clear it" are different requests:
   ```python
   class Arrange(_Inbound):
       """Ask the wall to show a given mirror. Absent fields are left alone;
       ``staged: null`` explicitly returns the displays to the wall. The caller
       does not have to be the display's operator — see ``SECURITY.md`` §2.
       """
       type: Literal["arrange"]
       staged: str | None = None
       fullscreen: bool | None = None
   ```
   Add `Arrange` to the `ClientMessage` discriminated union and re-export nothing
   else — the union is what `Hub._dispatch` switches on.
 2. `src/mirror/protocol.py` — `Hello` gains one field, single word so there is no
   camelCase alias to get wrong (but round-trip it anyway, A6):
   ```python
   #: true when this peer is a wall display that obeys the shared layout.
   kiosk: bool = False
   ```
   Keep `Role = Literal["sharer", "viewer"]` exactly as it is: a kiosk is a viewer
   with an attribute, not a third role (see the phase overview).
 3. `src/mirror/protocol.py` — add the outbound builder beside `welcome()`:
   ```python
   def layout(
     *, staged: str | None, fullscreen: bool, followers: int
   ) -> dict[str, Any]:
       """The wall's presentation state, pushed to every viewer as it changes."""
       return {"type": "layout", "staged": staged, "fullscreen": fullscreen, "followers": followers}
   ```
   Key order and spelling are the contract in `00_phase.md`; the outbound builders
   are hand-written dicts, so there is no alias generator to catch a typo here —
   the round-trip test in this task is what catches it.
 4. `src/mirror/protocol.py` — `welcome()` gains a `layout` parameter and a
   `"layout"` key so a page arrives already arranged. Give it a keyword-only
   default of `{"staged": None, "fullscreen": False, "followers": 0}`? **No** —
   a mutable default is a shared dict. Take it as a required keyword; the one
   caller (`Registry.join`) is updated in task 02, so this task must not leave a
   call site broken: update `registry.py`'s `welcome(...)` call in the same commit
   to pass `layout=protocol.layout(staged=None, fullscreen=False, followers=0)`
   as a placeholder that task 02 replaces with the real state.
 5. Do **not** touch `Hub`, `create_app`, `Registry` policy or any JS in this task.
 ## Testing & Quality
 - `tests/test_protocol.py` — extend the message-parsing suite:
  * `{"type":"arrange"}`, `{"type":"arrange","staged":null}` and
    `{"type":"arrange","staged":"p1","fullscreen":true}` all parse, and
    `model_fields_set` distinguishes the first two from the third (this is the
    whole reason the model is written this way — test it, do not trust it).
  * `hello` defaults `kiosk` to `False` and accepts `kiosk: true`.
  * `protocol.layout(...)` emits exactly `type/staged/fullscreen/followers` —
    assert the key set, which is how the outbound dicts are guarded elsewhere.
 - `tests/test_app.py` — `test_an_unknown_message_type_is_reported_but_survivable`
  must still pass, and `arrange` must *not* appear as unknown once task 03 lands;
  nothing to assert here yet.
 - Coverage: **>90%** on this task's new/modified code (the models and the builder
  are covered directly by the parse/shape tests above).

 # Task 02 — `Registry` owns the layout: set, validate, broadcast, fall back
 **Phase:** `07_kiosk_layout_state` · **Source:** `TODO.md:3` — "stores 'state' (fullscreen, which mirror is being viewed) that any client can manipulate and will update immediately"
 **Story:** n/a
 ## Objective
 The state itself, in `Registry`, with the policy that makes it trustworthy: only
 live mirrors may be named, the change reaches every viewer in the same call that
 produced it, and a mirror disappearing never leaves a display pointing at nothing.
 Pure Python, envelopes out — A8 to the letter.
 ## Work
 1. `src/mirror/registry.py` — a sentinel for "the caller did not mention this
   field", because `None` already means "clear it":
   ```python
   class _Unset:
       """Marker: the caller expressed no opinion, keep the current value."""
   UNSET = _Unset()
   ```
 2. `src/mirror/registry.py` — the state next to `Peer`/`Stream`, with the
   dataclass house style (`slots=True`):
   ```python
   @dataclass(slots=True)
   class Layout:
       """What the wall displays. One value per server process (A7): there is
       one wall, and every display obeying it is showing the same thing."""
       staged: str | None = None
       fullscreen: bool = False
   ```
   `staged` holds a stream id, which is also a sharer peer id (`streamId ==
   sharerId`, PLAN §3) — the fallback in step 6 relies on that identity.
 3. `src/mirror/registry.py` — `Peer` gains `kiosk: bool = False`; `Registry.join()`
   gains a `kiosk: bool = False` keyword and stores it. The follower count is
   derived, never bookkept: `sum(1 for p in self.peers.values() if p.kiosk)`.
 4. `src/mirror/registry.py` — `Registry.__init__` creates `self.layout = Layout()`;
   `join()` builds its `welcome` with `layout=self.layout_dto()` (replacing task
   01's placeholder), so a page is arranged before it asks.
 5. `src/mirror/registry.py` — the two public operations:
   * `layout_dto() -> dict[str, Any]` — `protocol.layout(staged=…, fullscreen=…,
     followers=<derived count>)`. This is the only place the DTO is built, so
     `/api/kiosk` (task 03) and the socket can never disagree.
   * `set_layout(peer_id, *, staged: Any = UNSET, fullscreen: Any = UNSET)
     -> list[Envelope]` —
     - `self._peer(peer_id)` first, so a dead peer gets `unknown_peer` like every
       other operation;
     - `staged` given as a non-`None` string → `self._stream(staged)` (reuses the
       existing `unknown_stream` code — no new error code);
     - `staged` explicitly `None` → clears; absent → unchanged; same shape for
       `fullscreen`;
     - if nothing actually changed, return **only** the ack to the sender — no
       broadcast storm from a controller that re-sends the same state;
     - otherwise return the broadcast: every peer whose role is `viewer`, **plus
       the sender** (a sharer that sends an `arrange` still gets its own ack),
       each carrying `protocol.layout(**self.layout_dto())`. Deduplicate the
       sender into the set so no peer is sent the frame twice.
 6. `src/mirror/registry.py` — the fallback, in `_drop_stream()` (the single funnel
   for *every* removal path: `unpublish`, disconnect, replaced stream, capacity
   eviction): if `self.layout.staged == stream.id`, set it to `None` and append
   the layout broadcast to the envelopes it already returns. The comment there
   already explains "tell every viewer, not just subscribers" — extend it: a
   display aimed at a mirror that vanished must fall back to the wall *in the same
   frame set*, because there is no polling to correct it later.
 7. `src/mirror/registry.py` — follower joins/leaves must also push state, or a
   controller sits on a stale `followers: 0` until someone moves a mirror:
   `join()` appends the layout broadcast to the other viewers' envelopes (not to
   the joiner — it got the state in its `welcome`), and `leave()` appends the same
   broadcast when the departing peer had `kiosk=True`.
 8. `src/mirror/registry.py` module docstring — add the invariant to the bulleted
   list: *the layout names either nothing or a live mirror; a mirror's removal
   clears it in the same envelope set.*
 9. Do **not** touch `Hub`, `app.py`, or any JS. Do not add persistence, a layout
   per peer, or an audio field (see `00_phase.md`, "What is deliberately not here").
 ## Testing & Quality
 - `tests/test_registry.py` — a new `TestLayout` class covering, in this order:
  * default state is the wall, not fullscreen, zero followers;
  * `set_layout` with `staged="pX"` broadcasts to viewers **and** the sender, and
    no peer receives it twice;
  * `staged` absent + `fullscreen=True` changes only fullscreen (the
    partial-update rule, asserted on the returned DTO);
  * `staged=None` clears an existing selection, and `set_layout` with no fields at
    all produces no broadcast;
  * an unknown stream id raises `RegistryError` with `code == "unknown_stream"`
    and leaves `self.layout` untouched;
  * a second `set_layout` with identical values sends the ack and nothing else;
  * `unpublish`, `leave()` of the sharer, and a *replaced* stream each reset
    `staged` to `None` and emit exactly one layout frame per viewer;
  * `followers` counts only `kiosk=True` viewers, and a kiosk joining/leaving
    pushes a layout frame whose `followers` is the new count;
  * `welcome` of a peer that joins **after** an `arrange` carries that state —
    this is "navigate to `/kiosk` and it arranges itself", stated at the layer
    where it is decided.
  Use the file's existing helpers/idioms (explicit peer ids via `id_factory`, the
  `codes_and_targets` style helpers already in the module) rather than a new
  harness.

 # Task 03 — Socket dispatch, `GET /api/kiosk`, and the wire suite
 **Phase:** `07_kiosk_layout_state` · **Source:** `TODO.md:3` — "state … that any client can manipulate and will update immediately so I can just navigate to that endpoint on the kiosk and it will automatically arrange itself"
 **Story:** n/a
 ## Objective
 Connect the frames to the transport and make the state readable without a
 browser: `Hub` accepts `arrange` from any peer and passes the caller's *expressed*
 fields to `Registry`, and `GET /api/kiosk` answers the same DTO the socket pushes.
 After this task the feature is real and drivable with `websocat`, one step below
 the browser.
 ## Work
 1. `src/mirror/app.py` — `Hub._introduce`: pass the flag through,
   `self.registry.join(role=hello.role, name=hello.name, device=hello.device,
   kiosk=hello.kiosk)`.
 2. `src/mirror/app.py` — `Hub._dispatch`, in the existing `isinstance` chain
   before the `else` that marks the union exhaustive:
   ```python
   elif isinstance(message, protocol.Arrange):
       fields = message.model_fields_set
       outbox = self.registry.set_layout(
           peer_id,
           staged=message.staged if "staged" in fields else UNSET,
           fullscreen=message.fullscreen if "fullscreen" in fields else UNSET,
       )
   ```
   Import `UNSET` from `.registry`. `model_fields_set` is the one place the
   "absent ≠ null" rule survives the trip from JSON to policy; a comment there
   should say so, because the next reader will try to simplify it to
   `message.staged` and silently lose "back to the wall".
 3. `src/mirror/app.py` — the read endpoint, next to `/api/streams`, same
   `Cache-Control: no-store` (a roster that is cached is a lie about what is on
   the wall right now):
   ```python
   @app.get("/api/kiosk")
   async def kiosk_layout() -> JSONResponse:
       """Server truth about the wall display: what is on stage, fullscreen, and
       how many displays are obeying it. Read-only by design — the only writer is
       the `arrange` frame on /ws, so there is one path that can change the wall."""
       return JSONResponse(registry.layout_dto(), headers={"Cache-Control": "no-store"})
   ```
   ASSUMPTION: writes stay on the WebSocket only. An HTTP `POST` would be a second
   write path with no authentication (A11) and no same-origin protection to lose,
   and the WS already gives any admitted address the same power — so the read-only
   endpoint buys the `curl` debugging (AGENTS.md §8) without buying a new surface.
 4. `src/mirror/app.py` — **do not** add `/kiosk` to `PAGES` yet: there is no page
   until phase 08. `/api/kiosk` is gated like every other route (only `/healthz`
   is exempt, AGENTS.md §3), and must not be added to that exemption.
 5. No JS in this task.
 ## Testing & Quality
 - `tests/test_app.py` — extend `TestSignalingSocket` (or the class the existing
  roster tests live in) with:
  * the round-trip: sharer publishes, viewer connects, viewer sends
    `{"type":"arrange","staged":<streamId>,"fullscreen":true}` → both the sender
    and a second viewer receive `layout` with `staged` and `fullscreen` set, and
    `GET /api/kiosk` says the same;
  * `followers` — two viewers with `hello{kiosk:true}` and one plain viewer
    report `followers: 2`, and closing one of the kiosk sockets pushes a layout
    frame that says `1`;
  * a bad stream id answers `error{code:"unknown_stream"}` and **does not** close
    the socket (send `ping`, get `pong`);
  * an `arrange` with only `fullscreen` leaves `staged` alone end to end, and
    `arrange{staged:null}` returns the wall;
  * a **sharer** that sends `arrange` gets the ack, and a layout frame is not
    pushed to other sharers (viewers plus sender only);
  * the staged mirror's sharer disconnects → every viewer gets `staged: null`.
 - `tests/test_app.py::TestAddressGate` — `/api/kiosk` is refused with the rest of
  the app: add it to the parametrised "refused address gets nothing" list and
  assert a refused address never learns the layout, plus one test that the real
  address gets `200` and `cache-control: no-store`.
 - `tests/test_app.py::TestConfigEndpoints`-style shape check: `/api/kiosk` returns
  exactly the three keys (`staged`, `fullscreen`, `followers`) so a future field
  addition is a decision, not a leak.
 - Coverage: **>90%** on this task's new/modified code.
 ## Completion Criteria
 - [ ] `websocat ws://localhost:8055/ws` can drive the wall by hand: `hello`, then

 # Phase 08 — The `/kiosk` page: a wall that arranges itself
 **Source:** `TODO.md` L3 — "Add a /kiosk endpoint … so I can just navigate to that endpoint on the kiosk and it will automatically arrange itself to the client's preferences." (the display-client half of that item)
 **Story:** n/a
 **Context:** `.agents/PLAN.md` §2 A9 (hand-written ES modules, no framework/bundler), A10 (nothing from outside the origin), A13 (Playwright, `channel="chromium"`); `AGENTS.md` §6 (reuse `net.js` rather than duplicating socket logic; ids must not collide across pages); phase 01 (`01_keyboard_kiosk_control` — the keyboard router, the stage mechanics, the mouseless rule); phase `07_kiosk_layout_state` (the `arrange`/`layout` contract, `hello.kiosk`, `GET /api/kiosk`); `src/mirror/static/watch.js`, `watch.html`, `app.css`, `net.js`; `docs/kiosk-silverblue.md` (the target box: Firefox `--kiosk`, **no keyboard, no mouse, no console**)
 ## Objective
 `GET /kiosk`: a chrome-free wall for an unattended display that subscribes to every
 mirror like `/watch` does and then **does what the server state says** — stages the
 mirror the state names, fullscreen or not — on arrival and on every change, with no
 input from anyone standing at the box.
 The phase is deliberately two halves:
 1. **Make the wall reusable** (tasks 01–02). `/kiosk` must not fork 400 lines of
   tile/WebRTC/stage code (`AGENTS.md` §6: reuse, don't duplicate), so the wall's
   core moves out of `watch.js` into `static/wall.js` and both pages consume it.
   Those two tasks change **no behaviour** — phases 01–06's suites are the gate.
 2. **Build the page on it** (tasks 03–05): the route, the markup, the layout
   applier, and the browser proof.
 ## Rules this page lives by
 * **Arrival is arrangement.** `welcome.layout` is applied before the first roster
  tile finishes painting. A person who points a kiosk at `/kiosk` must not have to
  touch it.
 * **The state is the boss, locally too.** A keypress on the kiosk performs the
  action *and* publishes it (`arrange`), so the controller and the display cannot
  disagree — same as every other shared state: one writer path, everyone re-reads.
 * **Fullscreen is best-effort, the stage is the guarantee.** A remote command
  carries no user activation, so `requestFullscreen()` may be refused; the in-page
  stage fills the viewport anyway and the Silverblue window manager already forces
  the window fullscreen (`docs/kiosk-silverblue/window-config.ini`). The page asks
  and never blocks on the answer — exactly the stance phase 01 documented for `f`.
 * **Never invent state.** No auto-staging of the newest mirror, no remember-last
  across a server restart. An empty state means the wall.
 * **No audio commands.** The layout carries no sound field (phase 07,
  `SECURITY.md` §4); a display never becomes audible because a stranger asked.
 * **The chrome stays off the screen.** No header bar, no "Share a screen" button,
  no counts in a title bar — a display shows mirrors. The three shared ids
  (`net`, `notice`, `toast`) are the only elements `/kiosk` may share with another
  page, and `#net` stays because the connection state is the one thing that must be
  legible in a screenshot of a wall nobody is looking at.
 ## Dependencies
 - `07_kiosk_layout_state` (todo) — the `arrange`/`layout` frames, `hello.kiosk`,
  `welcome.layout`, the `followers` count, `GET /api/kiosk`. Task 01 of this phase
  has no dependency on it and may run first, but the phase is not complete until
  07 exists.
 - `01_keyboard_kiosk_control` (complete) — the router, `stage()`/`unstage()`, the
  mouseless rule and the pointer-free suite this phase extracts and extends.
 - `06_sharer_quality_presets` (complete) — the current behaviour of the wall.
 ## Tasks
 1. `01_extract_wall_tiles_and_stage.md` — the tile/peer/stage/mute core of
   `watch.js` becomes `static/wall.js` (`createWall()`); `app.css` re-keys the
   stage rules from `#watch-stage` to a `.stage` class. No behaviour change.
 2. `02_extract_wall_key_router.md` — the single `keydown` switch becomes
   `installWallKeys()` in `wall.js`, dispatching named commands to the page;
   `/watch`'s key map is byte-identical in effect.
 3. `03_kiosk_page_and_route.md` — `static/kiosk.html`, `GET /kiosk` in `app.py`
   (and in `PAGES` for `no-store`), and every structural guard in `test_app.py`
   extended to a third page.
 4. `04_kiosk_layout_applier.md` — `static/kiosk.js`: `hello{kiosk:true}`, the wall
   from `createWall()`, `applyLayout()` on `welcome`/`layout`, and local keys
   published back with `arrange`.
 5. `05_kiosk_layout_e2e_and_docs.md` — `tests/e2e/test_kiosk_layout.py`: a real
   sharer, two kiosk displays (isolated contexts, hence separate sockets and peer
   ids), and the assertion that one display's keypress re-arranges the other,
   proved on the second display's decoded pixels; plus the `/kiosk` docs.
 ## Testing & Quality
 - **Refactor gate (tasks 01–02)**: `tests/e2e/test_keyboard_wall.py`,
  `test_live_mirror.py`, `test_audio_share.py`, `test_stage_autofade.py`,
  `test_share_layout.py` pass **unedited**. A changed assertion in one of them
  during a "behaviour-preserving" extraction is a bug report, not a fix.
 - **Structure gate (task 03)**: `test_app.py`'s guards extended — page renders,
  `no-store`, `node --check`, every `$("#id")` exists, ids do not collide across
  *three* pages, `<video>` is `muted playsinline`, nothing from a CDN, the address
  gate refuses `/kiosk` like the rest of the app. A new guard: `static/wall.js`
  contains **no** `$("#…")` — one module serving two pages takes its elements as
  arguments or it will look them up in the wrong document.
 - **Behaviour gate (tasks 04–05)**: a dedicated Playwright suite, pointer-free like
  phase 01's (a mouse on the kiosk would defeat the point), asserting on the
  *second* display's `<video>` (`videoWidth`, distinct frames via the `conftest`
  `frames_matching()` helper) and on `data-layout`/`data-fullscreen` — never on
  whether a handler ran. Fullscreen is asserted on the stage class, not on
  `document.fullscreenElement`, which the browser may legitimately refuse.
 - Coverage: **>90%** on new/modified code. The Python surface added here is one
  route; the JS is covered by browser assertions, per `AGENTS.md` §4.

 # Task 01 — Extract the wall (tiles, peers, stage) into `static/wall.js`
 **Phase:** `08_kiosk_page` · **Source:** `TODO.md:3` — "a /kiosk endpoint which stores 'state' (fullscreen, which mirror is being viewed) … [that] will automatically arrange itself" (the wall has to exist twice before a page can arrange it)
 **Story:** n/a
 ## Objective
 Move the wall's core out of `watch.js` into a reusable `static/wall.js` module that
 takes its elements and its socket from the page, and have `watch.js` consume it.
 **Pure refactor: `/watch` must behave and look exactly as it did.** The kiosk page is
 impossible without this, and forking the tile/WebRTC code instead would violate
 `AGENTS.md` §6.
 ## Work
 1. `src/mirror/static/wall.js` (new) — a factory, no document queries, no socket of
   its own, no top-level side effects beyond the export:
   ```js
   /**
    * The wall: one tile per live mirror, one RTCPeerConnection per tile, and a
    * stage the staged tile's own element moves into (so its <video> and its
    * connection never restart — AGENTS.md §6).
    *
    * Nothing here queries the document: the page hands over the elements it owns,
    * because one module now serves /watch, /kiosk and (phase 09) /remote, whose
    * ids must not collide (test_the_two_pages_share_no_element_ids…).
    *
    * @param {{grid: Element, stageEl: Element, template: HTMLTemplateElement,
    *          send: (payload: object) => boolean,
    *          onChange?: (summary: {mirrors: number, live: number}) => void,
    *          stats?: boolean}} options
    */
   export function createWall(options) { … }
   ```
   Return the surface the pages need — at minimum `absorb(stream)`,
   `drop(streamId)`, `onSignal(message)`, `stage(streamId, options)`,
   `unstage(options)`, `setMuted(tile, muted)`, `ordered()`, `selectedId()`,
   `setSelected(streamId)`, `moveSelection(delta)`, `tile(id)`, `closePeers()`, and
   a `stagedId()` accessor. Keep the existing function bodies as the implementation;
   the change is *which object owns the state*, not what the code does.
 2. `src/mirror/static/wall.js` — move, verbatim except for the `ui.`/`state.` reads
   the factory replaces, from `watch.js`: `tiles`, `makeTile`, `paintTile`,
   `dropTile`, `closePeer`, `ensurePeer` (with its `ontrack`/`onicecandidate`/
   `onconnectionstatechange` handlers and the retry-with-backoff), `onSignal`,
   `setMuted`, `subscribe`, `absorb`, `orderedTiles`, `stage`, `unstage`,
   `revealStageControls` + `stageRevealTimer` + `STAGE_REVEAL_IDLE_MS`,
   `fullscreenExitInFlight`, and the stats ticker. Every comment that explains *why*
   (the single-MediaStream-per-tile story, the audio-only-on-stage policy, the
   fullscreen-exit race, "never move `srcObject`, move the element") travels with
   the code — those comments are why phases 01–06 do not get re-broken.
   `renderCounts()` does **not** move: it writes `#counts`/`#empty`, which are
   `/watch` elements. The wall calls `onChange({mirrors, live})` wherever
   `renderCounts()` is called today, and `watch.js` keeps its own `renderCounts()`
   as that callback.
 3. `src/mirror/static/wall.js` — the socket is the page's. Take `send(payload)` and
   use it wherever the moved code used `state.ws.send(...)`
   (`subscribe`, ICE candidates, the retry's re-`subscribe`), and guard on its
   truthiness the way the code guards on `state.ws` today. This is what lets a page
   whose socket is not open yet build a wall, and what keeps `net.js` as the only
   place a socket exists (`AGENTS.md` §6).
 4. `src/mirror/static/watch.js` — delete the moved code, import
   `{ createWall }` from `./wall.js`, build the wall after `loadConfig()` with the
   elements already in its `ui` map (`grid`, `stage`, `template`) and
   `send: (payload) => state.ws.send(payload)`, and call `wall.absorb/drop/onSignal`
   from the `onMessage` switch, `wall.closePeers()` from `onClose`,
   `wall.stage/unstage/…` from the key router (task 02 moves the router itself).
   Keep in `watch.js`: the config load, the socket, `renderCounts`, `setNet`, the
   help overlay, the `focusin` handler (via `wall.setSelected`), the refusal notice,
   the share link.
 5. `src/mirror/static/watch.js` — keep the `fullscreenchange` listener **in the
   page** (it is a page policy: `/watch` unstages when the browser leaves
   fullscreen; the kiosk will do something different, phase 08 task 04), calling
   `wall.unstage()`. The `fullscreenExitInFlight` flag it depends on moves into
   `wall.js`, so expose the flag's two behaviours through `unstage()`/a small
   `handleFullscreenChange(hasFullscreen)` hook — the shape is yours, but the race
   documented at watch.js L345–352 must stay closed.
 6. `src/mirror/static/app.css` — the stage rules are keyed to the `/watch` id and
   would not style a second page's stage. Add `class="stage"` to
   `<div id="watch-stage">` in `watch.html` (keep the id — the e2e suites and
   `watch.js` both select it) and re-key these selectors from `#watch-stage` to
   `.stage`, changing nothing else in the blocks: `#watch-stage { … }` (L565),
   `body.staged #watch-stage` (L574), `#watch-stage .tile` (L577),
   `#watch-stage .tile video`, `#watch-stage .tile .cap`, and the
   `#watch-stage .tile[data-audio="on"|"off"]::after` pair (L471, L477). No new
   `display` declarations, no `[hidden]` rules — `TestStylesheet` guards those.
 7. `src/mirror/static/watch.js` — the dead `if (ui.unstage) …` branch at L473: it is
   unreachable today (`ui` has no `unstage` key) and moving it would launder dead
   code into the new module. Delete it and leave a one-line comment saying the exit
   control is the per-tile `.exit` button, so nobody re-adds a second exit.
 8. Do **not** add `/kiosk`, `kiosk.html` or `kiosk.js` in this task, and do not
   change any key binding, DOM structure of the tile, or visual rule beyond the
   `#watch-stage` → `.stage` re-key.
 ## Testing & Quality
 - **The gate is the existing suites, unedited** (`AGENTS.md` §4/§5):
  `uv run pytest -m e2e -k "keyboard or live_mirror or audio or stage or share_layout"`,
  then the full `-m e2e`. These cover tile rendering, the stage transitions, audio
  policy, the autofade timing, and the peer-connection probes through
  `window.__probe` — i.e. exactly the machinery being moved.
 - `tests/test_app.py` — `test_scripts_parse_as_es_modules` gains `"wall.js"`,
  `test_static_assets_are_served` gains `"wall.js"`.
  `test_every_element_the_script_reaches_for_exists` must still pass for
  `watch.js` (the ids it still reaches for exist) — and add the new module rule:
  *`wall.js` must contain no `$("#…")`*, because a module shared by pages with
  different ids may never look an element up in the document it happens to be
  loaded in. Assert it as a source-level guard next to the others, with a comment
  naming `test_the_two_pages_share_no_element_ids_but_the_shared_chrome` as the
  reason it exists.
 - Visual check while working: `/watch` at 1280×800 and 390×844, staged and
  unstaged — the stage must be pixel-equivalent (the re-key must not change
  specificity in a way that reorders a rule).
 - Coverage: **>90%** on new/modified code — the moved code is covered by the e2e
  suites that already exercise it; the module has no new logic in this task.
 ## Completion Criteria

 # Task 02 — The key router becomes `installWallKeys()` in `wall.js`
 **Phase:** `08_kiosk_page` · **Source:** `TODO.md:3` — "the kiosk doesn't have a keyboard/mouse plugged in most of the time so I can't full screen/switch views" (the display must accept the same keys *and* report them)
 **Story:** n/a
 ## Objective
 Move `/watch`'s single `keydown` switch into `wall.js` as `installWallKeys()`, so
 `/kiosk` gets the identical key map for free and — this is the point — can publish
 what a key did instead of only performing it. Again **no behaviour change on
 `/watch`**: phase 01's pointer-free suite is the gate.
 ## Work
 1. `src/mirror/static/wall.js` — export the router, keeping the invariant phase 01
   wrote down (one listener, one switch; every command is a case here, never a new
   listener):
   ```js
   /**
    * The one keydown listener for a wall page. It maps keys to named commands and
    * hands them to the page; it never decides what a command does to shared state.
    *
    * A page returns `true` only when the key actually changed something — the
    * router calls `preventDefault()` on exactly those, which is today's discipline
    * on /watch (`g` unstaged and `Esc` with nothing open are not "handled" and keep
    * their browser default).
    *
    * Never intercepted: any chord with Ctrl/Cmd/Alt (back, reload, copy belong to
    * the browser) and every key inside an <input>/<textarea>/<select>/contenteditable.
    *
    * @param {{wall: object, onCommand: (command: string, detail: {key: string, index?: number, event: KeyboardEvent}) => boolean, root?: Document}} options
    */
   export function installWallKeys(options) { … }
   ```
 2. `src/mirror/static/wall.js` — move `onWallKey`'s switch body into the module,
   translating each case into a command name, in this order and with these names
   (they are the contract `/kiosk` publishes against):
   | key(s) | command | detail |
   |---|---|---|
   | `j` `arrowdown` | `next` | — (module performs `wall.moveSelection(1)` itself, then reports handled) |
   | `k` `arrowup` | `previous` | — |
   | `enter` | `stage` | — |
   | `f` | `fullscreen` | — |
   | `g` | `wall` | — |
   | `n` / `p` | `step_next` / `step_previous` | — |
   | `m` | `mute` | — |
   | `?` | `help` | — |
   | `escape` | `escape` | — |
   | `1`–`9` | `jump` | `index` (0-based) |
   Keys are matched case-insensitively exactly as today (a caps-locked kiosk, a
   remote hand holding Shift). `next`/`previous` stay module-side because moving the
   selection is wall state, not page policy — the page still sees the command, so a
   page that wants to publish the new cursor can.
 3. `src/mirror/static/wall.js` — the "any keypress while staged reveals the
   overlay" behaviour (today `if (state.staged) revealStageControls();` before the
   switch) moves with it, *before* dispatch, and must not `preventDefault` —
   an unhandled key keeps flashing the caption, which is the debuggable outcome
   phase 01 documented.
 4. `src/mirror/static/wall.js` — commands that are pure wall operations
   (`stage`, `wall`, `step_*`, `mute`, `jump`) get a **default implementation in the
   module** used when the page returns nothing for them, so `onCommand` can be a
   thin observer. `stage`/`jump` resolve their target with today's rule (the
   selected tile, else the first; `toast` when the wall is empty — `toast` comes
   from `net.js`, which `wall.js` may import). `help` and `escape` have **no**
   default: they are page policy (`/watch` closes the `?` overlay before leaving the
   stage), and a page that ignores them must not break the router.
 5. `src/mirror/static/watch.js` — delete `onWallKey`, `moveSelection`,
   `stageSelectedOrFirst`, `stepStage`, `toggleHelp`'s key wiring and the
   `document.addEventListener("keydown", …)` line; call
   `installWallKeys({ wall, onCommand })` instead, where `onCommand` keeps today's
   exact behaviour for `help` (toggle `#wall-help`, return whether it changed) and
   `escape` (overlay first, then `wall.unstage()`, return whether either happened),
   and returns `false`/nothing for the commands the module already performs.
   `?`'s "focus is deliberately never touched" comment moves with the behaviour.
 6. `src/mirror/static/watch.js` — keep `focusTile`, `setSelected` and the grid's
   `focusin` handler as they are now that they call into `wall` (task 01); Tab must
   still agree with `j`/`k`.
 7. No new page, no route, no kiosk markup in this task.
 ## Testing & Quality
 - **The gate**: `uv run pytest tests/e2e/test_keyboard_wall.py` **unedited** — the
  file drives every binding with `page.keyboard.press()` and asserts the DOM result,
  and its meta-test forbids the pointer in itself. If a case fails, the router moved
  wrong; do not touch the test.
 - `tests/test_app.py` — add one source-level guard in the spirit of the existing
  ones: `installWallKeys` is defined in `wall.js` and `watch.js` contains **no**
  `addEventListener("keydown"` — the "one listener per wall page" rule should fail
  the build when someone adds a second one, which was phase 01's whole point.
 - `uv run pytest -m e2e -k "keyboard or live_mirror or audio or stage"` green, then
  the whole `-m e2e`.
 - Coverage: **>90%** on new/modified code (the router is exercised by the browser
  suite on every binding).
 ## Completion Criteria
 - [ ] every key in phase 01's key map does on `/watch` exactly what it did before, asserted by `tests/e2e/test_keyboard_wall.py` with no edit
 - [ ] `grep -n 'addEventListener("keydown"' src/mirror/static/*.js` shows exactly one hit, inside `wall.js`

 # Task 03 — `GET /kiosk` and the page that hosts the wall
 **Phase:** `08_kiosk_page` · **Source:** `TODO.md:3` — "Add a /kiosk endpoint … so I can just navigate to that endpoint on the kiosk"
 **Story:** n/a
 ## Objective
 The endpoint and the markup: a chrome-free page whose only job is to hold a wall and
 expose the state a test (and a screenshot) can read. No layout behaviour yet —
 task 04 writes `kiosk.js` against this skeleton.
 ## Work
 1. `src/mirror/app.py` — the route, beside `/watch`, in the same shape:
   ```python
   @app.get("/kiosk", response_class=HTMLResponse, include_in_schema=False)
   async def kiosk_page() -> FileResponse:
       """A wall for an unattended display: subscribes like /watch and arranges
       itself from the shared layout (phase 07/08)."""
       return _page("kiosk.html")
   ```
   Add `"/kiosk"` to the `PAGES` tuple so the middleware keeps sending
   `Cache-Control: no-store` on it, like the other pages.
 2. `src/mirror/static/kiosk.html` (new) — model it on `watch.html` (same `<head>`,
   `/static/app.css`, the same inline `data:` favicon — **no** external asset, A10),
   `<title>Wall · mirror</title>` — `docs/kiosk-silverblue/check-kiosk.sh` proves a
   client is showing what it should by grepping the served page's `<title>`, so this
   string is a contract, not a label (phase 09 task 03 widens that check to accept
   it) — and these elements and nothing else:
   * `<body class="kiosk" data-layout="wall" data-fullscreen="false">` — the two
     layout knobs, mirrored onto the body so a screenshot and a test can read the
     state without reaching into JS (`docs/kiosk-silverblue/dim-probe.py` judges a
     wall from a screenshot; `data-audio` on a tile exists for the same reason).
   * `<main class="grid" id="kiosk-grid" hidden>` and `<div class="empty" id="kiosk-empty">`
     — the classes are what the stylesheet and `wall.js` select; the ids are page-unique.
     The empty state reads "No mirrors live" plus
     `Share from <code id="kiosk-share-url">…</code>` — `kiosk.js` fills that with
     `location.origin + "/mirror"`, because nobody is standing at the box to click
     anything and the person reading the screen needs a URL to type elsewhere.
   * `<div class="stage" id="kiosk-stage" aria-live="polite">` — **`class="stage"`
     is mandatory**: task 01 re-keyed the staging rules off `#watch-stage`, and
     without the class the kiosk stage would be an unstyled `div`.
   * the shared chrome ids and only these: `<span class="net" id="net"
     data-state="connecting"><i></i><span>connecting…</span></span>`,
     `<div class="notice" id="notice" hidden>`, `<div class="toast" id="toast" hidden>`.
     `#net` is not decoration — it is how a wall reports "the server is gone" in a
     screenshot, and every e2e `device()` helper waits on it.
   * `<template id="kiosk-tile-template">` — a copy of `watch.html`'s
     `#tile-template` tile (`article.tile[tabindex=0][data-state=connecting]`,
     `<video autoplay playsinline muted>`, `.badge`, `.actions` with `.audio` and
     `.expand`, `.cap` with `.title`/`.sub`/`.exit`). Name it
     `kiosk-tile-template`, never `tile-template`: the id-collision guard is the
     reason two pages may not share an id, and relaxing it for convenience is how
     the `#stage` bug happened.
   * `<div class="hud" id="kiosk-hud" aria-live="polite">` — one line the script
     owns: `N mirrors · wall` / `… · <label> · fullscreen`. It is the wall's
     self-description for a room with no keyboard.
   * **No** `<header class="bar">`, no counts in a title bar, no "Share a screen"
     link: a display shows mirrors.
   * `<script type="module" src="/static/kiosk.js">` — task 04 writes it; create a
     placeholder `kiosk.js` in this task that only imports `loadConfig` and
     `refusalNotice` from `./net.js` so the page parses, serves and shows a refusal
     notice, and nothing more.
 3. `src/mirror/static/app.css` — the new page's chrome only: `.kiosk` (no header
   space, full-bleed grid), `.kiosk .net` (fixed top-right, the same pill), `.hud`
   (fixed bottom-left, `--mono`, `--fg-dim`, small, `pointer-events: none`). Do not
   duplicate any stage/tile rule — those are `.stage`/`.tile` now. Add no rule whose
   selector mentions `[hidden]` and no `display` declaration on a component the
   stylesheet already owns (`TestStylesheet` guards both).
 4. `src/mirror/static/index.html` — a third `<a class="card" href="/kiosk">`
   ("GET /kiosk — An unattended wall") so the endpoint is discoverable from `/`.
   Cards carry no ids, so the id guard is unaffected.
 5. Do **not** touch `/remote` (phase 09), `watch.html`, or the layout applier.
 ## Testing & Quality
 - `tests/test_app.py` — extend the structural guards to the third page; each of
  these is an existing test gaining a case, not a new invention:
  * `TestPages::test_pages_render` → `("/kiosk", "kiosk-tile-template")`;
  * `test_pages_are_not_cacheable` → `client.get("/kiosk")` is `no-store`;
  * `test_static_assets_are_served` → `kiosk.js`;
  * `test_scripts_parse_as_es_modules` → `"kiosk.js"` (`node --check`);
  * `test_every_element_the_script_reaches_for_exists` → `("kiosk.js", "kiosk.html")`;
  * `test_both_pages_load_the_stylesheet_and_their_module` → the `kiosk.html` /
    `kiosk.js` pair (rename it if the name now lies — the guard matters more than
    the name);
  * `test_videos_are_muted_and_inline_so_autoplay_is_not_blocked` → `kiosk.html`
    (both autoplay rules apply to a kiosk: iOS/Safari blocks the wall otherwise);
  * `test_the_two_pages_share_no_element_ids_but_the_shared_chrome` → add
    `kiosk.html` to the ids map and assert `kiosk ∩ watch`, `kiosk ∩ mirror`,
    `kiosk ∩ index` are all exactly `{"net","notice","toast"}`. Keep the existing
    assertions verbatim; `#kiosk-*` prefixes are what make these pass.
  * add `#kiosk-grid`, `#kiosk-stage`, `#kiosk-hud` to the "elements a page must
    have" style check if the file has one, and assert `class="stage"` appears on
    `#kiosk-stage` **and** `#watch-stage` — a page whose stage lost the class
    renders a full-size unstyled video, which is exactly the class of bug the
    stylesheet guards exist for.
 - `tests/test_app.py::TestAddressGate` — `/kiosk` joins the parametrised "a refused
  address gets no page, no roster, no assets" list, and one test that an admitted
  address gets `200`.
 - `tests/e2e/test_live_mirror.py` — the refused-address parametr list
  `("/mirror", "/watch")` gains `"/kiosk"`, and its
  `expect(page.locator("#start, #grid, #notice")).to_have_count(0)` selector list
  gains `#kiosk-grid` / `#kiosk-stage` so the assertion actually covers the new page.
 - Coverage: **>90%** on new/modified Python (one route — covered by the page tests).
 ## Completion Criteria

 # Task 04 — `kiosk.js`: obey the layout, publish the keystrokes
 **Phase:** `08_kiosk_page` · **Source:** `TODO.md:3` — "state (fullscreen, which mirror is being viewed) that any client can manipulate and will update immediately so I can just navigate to that endpoint on the kiosk and it will automatically arrange itself to the client's preferences"
 **Story:** n/a
 ## Objective
 The behaviour: `/kiosk` opens, subscribes to every mirror, and arranges itself from
 `welcome.layout` without being touched; every `layout` frame that follows re-arranges
 it; and a keypress on the box — rare, but it happens when a keyboard is plugged in to
 diagnose — performs the change **and** publishes it, so the controller and the display
 converge instead of disagreeing.
 ## Work
 1. `src/mirror/static/kiosk.js` — replace task 03's placeholder. Module shape, in
   the order `watch.js` uses it: `loadConfig()` → `rtcConfig()` → `ui` map →
   `createWall()` → `connectSignaling()` → `installWallKeys()`. The `ui` map is
   `grid`, `stage`, `template`, `empty`, `shareUrl`, `hud`, `net`, `toast`, `notice`
   — every one of them exists in `kiosk.html` (the element guard proves it).
 2. `src/mirror/static/kiosk.js` — announce as a display, not a controller:
   `state.ws.send({type:"hello", role:"viewer", kiosk:true, name:"", device: deviceLabel()})`.
   `deviceLabel()` comes from `net.js`. `kiosk:true` is what feeds `followers`, and a
   `/kiosk` page must be counted while a `/remote` page must not.
 3. `src/mirror/static/kiosk.js` — the applier, the one function that touches the
   stage:
   ```js
   /**
    * Make the page match the server's layout. Idempotent: a frame that repeats
    * what is already applied changes nothing, so a controller that re-sends (or a
    * follower join that re-broadcasts) cannot re-request fullscreen forever.
    *
    * The caller is never trusted to have waited: `staged` names a live mirror when
    * the server accepts it, and may have died on the way here, so an unknown id
    * keeps the wall and is retried by the next roster frame.
    */
   function applyLayout(next) { … }
   ```
   * `next.staged` is a tile the wall has → `wall.stage(id)`; is `null` →
     `wall.unstage()`; names something unknown → unstage and remember the intent,
     re-applying whenever `absorb()` gains that tile.
   * `next.fullscreen` → request on the same target `/watch` uses (the stage element
     when staged, `document.documentElement` for the wall), `.catch(() => {})` and
     never awaited. A remote command carries no user activation: the request is a
     courtesy, the `.stage` CSS is the guarantee, and the Silverblue window is
     already fullscreen (`docs/kiosk-silverblue/window-config.ini`). Say exactly that
     in a comment — the next reader will otherwise "fix" it by awaiting.
   * Mirror both knobs onto the body — `document.body.dataset.layout =
     staged ? "stage" : "wall"` and `document.body.dataset.fullscreen = "true"|"false"`,
     and set `document.title` to the staged mirror's label (`"mirror — <label>"`, else
     `"mirror — wall"`), because a window list and a screenshot are the only views a
     headless box offers.
 4. `src/mirror/static/kiosk.js` — apply on arrival and on every change:
   `welcome` → `applyLayout(message.layout)` (before `renderCounts()`-equivalent work,
   so the wall never flashes between the roster and the stage), `layout` →
   `applyLayout(message)`. `stream_added`/`stream_updated` → `wall.absorb()` then
   `applyLayout(state.layout)` so a remembered intent lands the moment its tile does.
   `stream_removed` → `wall.drop()` (the server pushes the cleared layout behind it —
   do not "helpfully" unstage locally, or two frames will fight).
 5. `src/mirror/static/kiosk.js` — the keys, via `installWallKeys({wall, onCommand})`,
   each entry doing the local change **and** publishing the same intent:
   | command | local effect | published `arrange` |
   |---|---|---|
   | `next` / `previous` | (module moves the selection) | none — the cursor is local to this page |
   | `stage` (`Enter`) | `wall.stage(cursor ?? first)` | `{staged: <id>}` |
   | `wall` (`g`), `escape` | `wall.unstage()` | `{staged: null}` |
   | `step_next` / `step_previous` | stage the neighbour | `{staged: <id>}` |
   | `jump` (`1`–`9`) | stage the Nth | `{staged: <id>}` |
   | `fullscreen` (`f`) | re-request fullscreen | `{fullscreen: true}` |
   | `mute` (`m`) | `wall.setMuted(tile, …)` | **none** |
   `mute` is never published, and the code must say why in one comment line:
   `SECURITY.md` §4 — sound only ever starts from a gesture on the device that plays
   it, so a display must not become audible because another machine asked. `help`
   (`?`) has no target on this page (no overlay markup) and returns not-handled.
 6. `src/mirror/static/kiosk.js` — what the page does **not** publish: the browser's
   own fullscreen exits. Register no `fullscreenchange` policy that unstages (the WM
   dropping fullscreen is not a person asking to leave the stage — on `/watch` that
   is a deliberate choice, on a wall it would fight the state) and do not echo
   `fullscreen:false` because the browser refused a request; that would make a
   controller's "fullscreen" button look broken and would be reporting the browser's
   refusal as a user preference.
   ASSUMPTION: publish what a person asked for, not what the browser conceded.
 7. `src/mirror/static/kiosk.js` — the honest-but-quiet details:
   * `onChange({mirrors, live})` → `#kiosk-hud` text (`3 mirrors · wall`,
     `3 mirrors · Alice's laptop · fullscreen`) and the `#kiosk-grid`/`#kiosk-empty`
     `hidden` toggles `/watch` does in `renderCounts()`;
   * `#kiosk-share-url` gets `location.origin + "/mirror"` on load;
   * `refusalNotice(config)` → `showNotice(ui.notice, …)` and never open a socket,
     exactly as `/watch` does;
   * `onClose` → `wall.closePeers()` and mark the tiles stale; the next `welcome`
     re-applies the layout, which is what makes a server restart recover on its own.
 ## Testing & Quality
 - `tests/test_app.py` — the element guard from task 03 already forces every
  `$("#…")` in `kiosk.js` to exist; add one source-level guard that `kiosk.js`
  **never** sends a `mute`/audio field in an `arrange` frame (assert no `arrange`
  object literal in the file contains `muted`/`audio`) — the security rule should
  fail the build, not live in a comment.
 - `uv run pytest -m e2e` — `/watch`'s behaviour must be untouched by this task; the
  new page's behaviour is covered in task 05.
 - Manual, before task 05 exists: `uv run mirror serve`, two browser windows, one on
  `/kiosk`; drive the state with `websocat` (`{"type":"arrange","staged":"<id>"}`) and
  watch the page stage it — AGENTS.md §8's "reproduce at the lowest layer" ladder
  reversed: prove the layer works before automating it.
 - Coverage: **>90%** on new/modified code — the applier is exercised by task 05's
  suite; the guards above cover the security rules statically.
 ## Completion Criteria
 - [ ] a `/kiosk` tab opened **after** an `arrange` is already showing that mirror when it finishes loading (no flash of the wall)
 - [ ] an `arrange` sent from `websocat` re-arranges an open `/kiosk` tab within one frame

 # Task 05 — `tests/e2e/test_kiosk_layout.py` and the kiosk docs
 **Phase:** `08_kiosk_page` · **Source:** `TODO.md:3` — "will update immediately so I can just navigate to that endpoint on the kiosk and it will automatically arrange itself to the client's preferences"
 **Story:** n/a
 ## Objective
 Prove the two properties the TODO item actually claims — **it arranges itself on
 arrival** and **one client's action moves another client's display** — in a browser,
 on pixels, with no pointer anywhere near the display. Then write down how to point a
 real kiosk box at it.
 ## Work
 1. `tests/e2e/test_kiosk_layout.py` (new) — `pytestmark = [pytest.mark.e2e,
   pytest.mark.timeout(180)]`, and the file's own `device()` fixture copied in the
   suite's established shape (isolated context per device, `page.on("pageerror")` and
   `console` errors collected from the first line of each test — `AGENTS.md` §8),
   waiting on `#net` `data-state=online`.
   Isolated **contexts** are the right unit here: each is its own socket and peer id,
   which is what "another client" means to the server. The media path itself is
   already proven by `test_live_mirror.py`; this suite proves the *state* path and
   still asserts on real decoded frames so nothing is taken on trust.
 2. `tests/e2e/test_kiosk_layout.py` — the cases:
   * **arrival is arrangement**: sharer on `/mirror` + `start_sharing()`; drive the
     state from a driver page (`page.evaluate` over a plain `WebSocket` to `/ws`,
     `hello` then `{"type":"arrange","staged":<id>,"fullscreen":true}`); *then* open
     `/kiosk`; assert it settles staged — `body[data-layout="stage"]`,
     `#kiosk-stage .tile[data-stream="<id>"]`, and
     `frames_matching(kiosk, "#kiosk-stage video")` showing `width > 0` and
     `distinct >= 2`. The frame assertion is what proves media crossed to the
     display, not just a CSS class (`AGENTS.md` §5).
   * **immediate update across clients**: two `/kiosk` pages, no input on the second;
     press `Enter` on the first (a keypress, so the display stays pointer-free);
     assert the second page's `data-layout` flips to `stage`, its staged tile id
     matches, and `GET /api/kiosk` reports the same id — one action, two displays,
     one source of truth.
   * **stepping**: `n` then `p` on page A move page B through the mirrors (start two
     sharers; assert the staged `data-stream` on B changes and wraps).
   * **teardown is a state change**: `stop_sharing()` on the sharer → both kiosk pages
     return to `body[data-layout="wall"]` and `/api/kiosk` reports
     `{"staged": null, …}` — no display may sit on a dead tile.
   * **followers**: with one `/kiosk` open, `/api/kiosk` says `followers: 1`; open a
     `/watch` page (a plain viewer, not a display) and it still says `1`; close the
     kiosk and it says `0`.
   * **nothing lies**: every case asserts `errors == []`.
 3. `tests/e2e/test_kiosk_layout.py` — keep it pointer-free and say so in the module
   docstring, in phase 01's words ("a test that reaches for the mouse proves nothing
   about a kiosk"); add the same style of self-guard the keyboard suite uses if it
   fits (scan this file for `.click(` and fail on it) — the driver's raw `WebSocket`
   calls in `page.evaluate` are not a pointer and must be allowed explicitly rather
   than by loosening the rule.
 4. Do **not** assert on `document.fullscreenElement` anywhere: headless Chromium may
   refuse an element fullscreen without user activation and the real kiosk's window
   manager forces fullscreen anyway (`docs/kiosk-silverblue/window-config.ini`).
   Assert `body[data-fullscreen]` and the `.stage` state, which are what the app
   controls. A comment must say this, or the next reader will "strengthen" the test
   into a flake.
 5. `docs/kiosk-silverblue.md` — a section, *"Two endpoints: `/watch` and `/kiosk`"*:
   `/watch` is a person operating a wall, `/kiosk` is a display obeying a wall, the
   keys still work on `/kiosk` for the moment a keyboard is plugged in, and the
   controller side arrives in phase 09 (`/remote`). Point out the migration rule
   honestly: existing clients keep their own `MIRROR_KIOSK_URL`, so nothing changes
   under a box until its `kiosk.conf` is re-pointed and `gdm` restarted. Do **not**
   change `install-kiosk.sh`, `kiosk.conf`, `gnome-kiosk-script` or `check-kiosk.sh`
   in this phase — the default URL moves in phase 09, when there is a way to drive it.
 6. `README.md` — the page table gains the `/kiosk` row; the "Keys" section gains one
   sentence: the wall keys work on `/kiosk` too, and a change made there is what every
   other display follows.
 ## Testing & Quality
 - `uv run pytest tests/e2e/test_kiosk_layout.py -x` green on its own, then the whole
  `-m e2e` (the suites share one session-scoped server, so a leaked peer in the new
  file will show up as a tile count in someone else's test — clean up contexts via
  the fixture's finalizers, as the existing suites do).
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` stays green: `/kiosk` must not
  have changed what a real capture looks like to a viewer.
 - Coverage: this task adds no product code; it is the **behavioural** coverage the
  phase's JS relies on (the project's rule — media and page behaviour are asserted in
  a browser, not simulated in Python).
 ## Completion Criteria
 - [ ] `uv run pytest tests/e2e/test_kiosk_layout.py` green, including the arrival case and the two-display case
 - [ ] the two-display test passes with the second display never receiving a `click()`, `focus()` or `hover()` from the test

 # Phase 09 — `/remote`: the hand that drives the wall
 **Source:** `TODO.md` L3 — "…controllable by other clients. Problem is the kiosk doesn't have a keyboard/mouse plugged in most of the time so I can't full screen/switch views… that any client can manipulate" (the controller half of that item)
 **Story:** n/a
 **Context:** `.agents/PLAN.md` §2 A9 (no framework, no bundler), A10 (no external assets), A11/A19 (no accounts; the address gate is the access control); `SECURITY.md` §2/§3/§4; phases `07_kiosk_layout_state` (the contract) and `08_kiosk_page` (the display that obeys it); `src/mirror/app.py`, `src/mirror/static/{net.js,app.css}`, `docs/kiosk-silverblue/`
 ## Objective
 `GET /remote`: a page you open on the laptop or phone in your pocket. It lists the
 live mirrors and the wall's current state and offers three decisions — *show this,
 back to the wall, full screen* — each one an `arrange` frame the display obeys
 instantly. Stepping (`n`/`p`) stays on the wall pages: on a controller the direct
 choice is a row and a button, and a second copy of the wall's key map would be a
 second thing to keep in sync. It shows **no video and subscribes to nothing**: a
 controller must not consume a sharer's upstream just to know what to point at
 (`PLAN.md` §6, "Mesh upload = N × bitrate per sharer").
 `/remote` is its own page rather than a panel on `/watch` because the two questions
 are different — "what do *I* want to look at" and "what should the *room* see" — and
 collapsing them would either hijack every viewer's clicks or hide the controls behind
 a wall of tiles. `/watch` keeps its local staging exactly as phases 01–06 defined it.
 ## Rules this page lives by
 * **Read the state, never own it.** Every control reflects `layout` as the server
  pushed it, so two controllers, a kiosk's own keystrokes and a page reload all agree.
  A control never paints a result locally and hopes the server agrees.
 * **Media-free, and provably so.** No `RTCPeerConnection`, no `subscribe` frame, no
  `<video>`. The proof is a test on the server's own numbers: open `/remote` and
  `/api/streams` must still report zero watchers.
 * **Only buttons and text, focusable.** No custom key map here: `/watch`'s keys belong
  to a wall, and a second copy of them on a controller page is a second thing to keep
  in sync. Native `<button>`s are keyboard- and screen-reader-reachable and work on a
  phone, which is the device this page is for.
 * **Fullscreen is reported, not promised.** The page says what the state asks for and
  that a browser may refuse it; it never implies it verified another machine's
  fullscreen.
 * **No audio, ever.** Same rule as the display (`SECURITY.md` §4): the layout has no
  sound field and `/remote` does not invent one. A controller that could make a
  stranger's display talk is not a controller, it is a prank.
 ## Dependencies
 - `07_kiosk_layout_state` (todo) — `arrange`/`layout`, `followers`, `GET /api/kiosk`.
 - `08_kiosk_page` (todo) — the `/kiosk` display that makes a controller meaningful,
  and the e2e scaffolding (`device()`-style fixture, frame probe) this suite reuses.
 - `01_keyboard_kiosk_control` (complete) — the key map this page deliberately does
  **not** copy, and the mouseless rationale it serves.
 ## Tasks
 1. `01_remote_route_and_page.md` — `GET /remote` in `app.py` (+ `PAGES`),
   `static/remote.html` with the control cluster and status line, `app.css` for the
   list, entry links from `/watch` and `/`, and the `test_app.py` structural guards
   extended to a fourth page.
 2. `02_remote_controller_logic.md` — `static/remote.js`: the roster as a list (no
   media), the live layout readout with the `followers` count, the buttons that send
   `arrange`, and the convergence behaviour when someone else changes the state.
 3. `03_remote_e2e_docs_and_kiosk_url.md` — `tests/e2e/test_remote_control.py`
   (controller → display, asserted on the display's DOM and on `/api/streams`'
   watcher count), README + `SECURITY.md`, and the kiosk box's default URL moving to
   `/kiosk`.
 ## Testing & Quality
 - **Structure**: every `test_app.py` guard gains the `/remote` page — renders,
  `no-store`, `node --check` of `remote.js`, element-existence, the cross-page id
  rule now over four pages (`{"net","notice","toast"}` is still the only overlap),
  nothing from a CDN, the address gate refusing `/remote` like the rest.
 - **The media-free guarantee** is asserted twice, from both ends: a source-level
  guard that `remote.js` contains no `RTCPeerConnection` and no `subscribe` frame, and
  a browser test that the server's `watching`/`viewers` counters stay at zero with
  `/remote` open. One of them will catch a well-meant future "preview thumbnail".
 - **Behaviour**: `tests/e2e/test_remote_control.py` drives the controller with real
  clicks (a person with a mouse driving a machine that has none — that is the whole
  feature) and asserts on the *display's* DOM and on `/api/kiosk`, never on the
  controller's optimism.
 - Coverage: **>90%** on new/modified code; the Python surface is one route.
 ## Completion Criteria
 - [ ] with a `/kiosk` display open, clicking "Show on wall" in `/remote` puts that mirror on the display within one frame, asserted in the browser
 - [ ] "Back to the wall" and "Fullscreen" do the same, and a second `/remote` page updates without being touched
 - [ ] `/api/streams` reports zero watchers while only `/remote` is open — driving the wall costs a sharer nothing
 - [ ] `/remote` counts one follower per `/kiosk` and never counts itself
 - [ ] a controller keeps working when there is no display at all (`/api/kiosk` `followers: 0`, the controls are enabled, the state is still stored)
 - [ ] `uv run pytest tests/e2e/test_remote_control.py` green, then the full `-m e2e` and the `realdisplay` suite
 - [ ] README + `SECURITY.md` describe what a visitor can now do to someone else's wall; the Silverblue box's default URL is `/kiosk`

 # Task 01 — `GET /remote` and the controller page
 **Phase:** `09_wall_remote_page` · **Source:** `TODO.md:3` — "controllable by other clients … so I can't full screen/switch views"
 **Story:** n/a
 ## Objective
 The endpoint and the markup for the hand: a list of mirrors, a line that says what the
 wall is doing, and the buttons that change it. `remote.js` becomes real in task 02;
 here it is a stub that loads config and reports a refusal, so the page serves and the
 guards can be written first.
 ## Work
 1. `src/mirror/app.py` — the route beside `/kiosk`:
   ```python
   @app.get("/remote", response_class=HTMLResponse, include_in_schema=False)
   async def remote_page() -> FileResponse:
       """The controller: lists mirrors and drives the shared layout. Shows no
       media and subscribes to nothing — a controller must not cost a sharer
       bandwidth (PLAN.md §6)."""
       return _page("remote.html")
   ```
   Add `"/remote"` to the `PAGES` tuple so it is served `no-store` like the others.
 2. `src/mirror/static/remote.html` (new) — same `<head>` conventions as the other
   pages (app.css, inline `data:` favicon, no external asset), `<title>Remote ·
   mirror</title>`, and these elements only:
   * `<header class="bar">` with the brand and `<span class="net" id="net"
     data-state="connecting">…</span>` (the shared chrome).
   * `<div class="notice" id="notice" hidden>` and `<div class="toast" id="toast"
     hidden>` — the other two shared ids, nothing else may overlap with another page.
   * `<section class="wall-state" id="remote-state" aria-live="polite">` — the readout:
     `Wall: <label>` / `Wall: no mirror`, a fullscreen marker, and a follower clause
     `· 1 display following` / `· no display following`. Give the pieces stable hooks
     (`<span id="remote-staged">`, `<span id="remote-fullscreen">`,
     `<span id="remote-followers">`) so the text and the tests never have to parse a
     sentence.
   * `<div class="remote-controls">` with `<button class="btn" id="remote-back">Back
     to the wall</button>` and `<button class="btn ghost" id="remote-fullscreen"
     aria-pressed="false">Full screen</button>`.
   * `<ul class="mirror-list" id="remote-list">` — the mirror rows live in
     `<template id="remote-row-template">`: `<li class="mirror-row" data-stream>`,
     `.title`, `.sub`, `<button class="btn ghost show">Show on wall</button>`.
   * `<div class="empty" id="remote-empty">` for "No mirrors live" with the same
     `Share from <code id="remote-share-url">…</code>` line the kiosk page uses —
     the controller is usually the device that goes and asks somebody to share.
 3. `src/mirror/static/remote.js` (new, stub) — import `loadConfig`, `refusalNotice`,
   `showNotice`, `$` from `./net.js`; set `#remote-share-url`; open the socket enough
   to drive `#net` to `online` (the e2e `device()` helper waits on it) and say hello
   with `role:"viewer"` and **no `kiosk` flag**. Task 02 fills in the rest.
   ASSUMPTION: a controller is a plain viewer in the protocol; `followers` counts
   displays only, and that asymmetry is what makes "no display following" mean what it
   says.
 4. `src/mirror/static/app.css` — `.remote` page styles: `.wall-state` (a strip under
   the bar, `--mono` for the readout, `aria-live` friendly), `.mirror-list` /
   `.mirror-row` (one row per mirror, title + sub + button on one line, works down to
   320 px — the share page's narrow-viewport rules are the model),
   `.remote-controls` (button row, wraps). `[aria-pressed="true"]` on
   `#remote-fullscreen` gets the same accent treatment the tile audio button uses, so
   "on" looks the same everywhere in this app. No rule whose selector mentions
   `[hidden]`; no new `display` on an existing component (`TestStylesheet` guards).
 5. Entry points — the endpoint has to be findable from the pages a person already
   opens:
   * `src/mirror/static/watch.html` — `<a class="btn ghost" id="remote-link"
     href="/remote">Drive the wall</a>` in the header, before `#share-link`. `watch.js`
     needs no change for it (it is a plain link; the element guard only inspects ids
     the script reaches for).
   * `src/mirror/static/index.html` — a fourth `<a class="card" href="/remote">`
     ("GET /remote — Point the wall from another device"). Cards carry no ids.
 6. `src/mirror/static/kiosk.html` — nothing. The display must not link its way out of
   itself; a wall shows mirrors and no navigation.
 ## Testing & Quality
 - `tests/test_app.py` — extend the guards to the fourth page, same list as phase 08
  task 03: `test_pages_render` (`("/remote", "remote-row-template")`),
  `test_pages_are_not_cacheable`, `test_static_assets_are_served` (`remote.js`),
  `test_scripts_parse_as_es_modules` (`remote.js`),
  `test_every_element_the_script_reaches_for_exists` (`("remote.js", "remote.html")`),
  the stylesheet-and-module pair test, and
  `test_the_two_pages_share_no_element_ids_but_the_shared_chrome` with `remote.html`
  in the map — `remote ∩ watch`, `remote ∩ mirror`, `remote ∩ index`, `remote ∩ kiosk`
  all exactly `{"net","notice","toast"}`.
 - New guards for this page's one hard promise, next to the other source-level rules:
  * `remote.js` contains no `RTCPeerConnection` and no
    `type: "subscribe"`/`type:'subscribe'` string, and `remote.html` contains no
    `<video>` — a controller that streams is a bug, and it must fail the build, not
    get caught in review (the reason is stated in the test's docstring: `PLAN.md` §6's
    mesh cost).
  * `remote.html` declares `id="remote-state"`, `#remote-back`,
    `#remote-fullscreen`, `#remote-list` — the element guard already covers this once
    `remote.js` looks them up in task 02, but assert them here so task 01's stub and
    task 02's page cannot drift.
 - `tests/test_app.py::TestAddressGate` — `/remote` joins the refused-address list.
 - Coverage: **>90%** on new/modified Python (one route).
 ## Completion Criteria
 - [ ] `curl -s localhost:8055/remote` serves the page; `-I` shows `cache-control: no-store`
 - [ ] opening `/remote` shows the header with the net pill online, an empty "No mirrors live" state with the share URL, and no console errors
 - [ ] `/watch`'s header and `/`'s cards link to `/remote`, and `/kiosk` links to nothing

 # Task 02 — `remote.js`: read the state, send the intent
 **Phase:** `09_wall_remote_page` · **Source:** `TODO.md:3` — "state (fullscreen, which mirror is being viewed) that any client can manipulate and will update immediately"
 **Story:** n/a
 ## Objective
 Make the controller real: a list of mirrors built from the roster, a readout built
 from the server's `layout`, and buttons that change the wall by sending `arrange` —
 never by painting a result and hoping. The page's correctness rests on one rule: **the
 only thing it displays about the wall is what the server last told it.**
 ## Work
 1. `src/mirror/static/remote.js` — replace the stub's innards, keeping the `ui` map,
   the config/refusal path and the socket from task 01. Module-local state:
   ```js
   /** id -> {id, name, label, displaySurface, width, height, audio}, in server
    *  roster order (welcome.streams is oldest-first, stream_added appends). The
    *  controller keeps a list, not tiles: no <video>, no MediaStream, no
    *  RTCPeerConnection — see the "no media in a controller" guard in test_app.py. */
   const mirrors = new Map();
   let layout = { staged: null, fullscreen: false, followers: 0 };
   ```
 2. `src/mirror/static/remote.js` — roster handling: `welcome` seeds `mirrors`,
   `stream_added`/`stream_updated` upsert, `stream_removed` deletes, and each change
   re-renders the list and the readout (a staged mirror's label appears in the
   readout, so an update can change the readout without changing the list).
   `signal` frames are ignored — this page never negotiates, and it should still be
   true if a sharer misbehaves.
 3. `src/mirror/static/remote.js` — `renderMirrors()`: one `li.mirror-row[data-stream]`
   per mirror from `#remote-row-template`, title = `label || name || "Shared screen"`,
   sub = `name · surface · W×H · audio|silent` (reuse the same words `watch.js`'s
   `paintTile` prints, so the two pages describe a mirror identically), the row's
   `.show` button, and `data-on=""` on the row whose id is `layout.staged` with the
   button reading `On the wall` (plus `aria-current="true"`). Empty list →
   `#remote-empty` shown, list `hidden`.
 4. `src/mirror/static/remote.js` — `renderState()`: the three spans
   (`#remote-staged`, `#remote-fullscreen`, `#remote-followers`) are filled from
   `layout` and nothing else:
   * staged → the mirror's title, or `"(gone)"` for the frame-in-transit case where
     the server has not yet cleared it; `null` → `no mirror`;
   * fullscreen → `on` / `off`, and `#remote-fullscreen`'s `aria-pressed` and label
     (`Full screen: on`) follow the **server's** value;
   * followers → `N displays following` / `1 display following` / `no display
     following`. When it reads `no display following` the controls stay enabled and a
     one-line hint appears under them: the state is still stored, so pointing a kiosk
     at `/kiosk` immediately picks it up — that is the TODO's "navigate to it and it
     arranges itself", seen from the other end.
 5. `src/mirror/static/remote.js` — the three writers, each of which sends and then
   **waits**:
   ```js
   /**
    * Send an intent and let the server's `layout` frame paint it. Never update
    * `layout` here: with two controllers open, an optimistic local paint is a lie
    * the moment the other one acts, and a lie in the readout is worse than a
    * 40 ms delay.
    */
   function arrange(patch) {
     if (!state.ws.send({ type: "arrange", ...patch })) toast("not connected — nothing sent");
   }
   ```
   * row `.show` → `arrange({ staged: id })`;
   * `#remote-back` → `arrange({ staged: null })`;
   * `#remote-fullscreen` → `arrange({ fullscreen: !layout.fullscreen })` — toggling
     from the server-reported value, never from the button's own `aria-pressed`.
   Wire them once on the list container (event delegation on `#remote-list`, matching
   how `watch.js` handles per-tile buttons) so a re-render cannot orphan a listener.
 6. `src/mirror/static/remote.js` — the frames: `welcome` → seed `mirrors`, set
   `layout = message.layout`, render both; `layout` → set `layout`, `renderState()`
   **and** `renderMirrors()` (the `data-on` marker moved); `error` → `toast` the
   message (an `unknown_stream` from a stale row is exactly the case where silence
   would look like a broken button).
 7. `src/mirror/static/remote.js` — the honest edge cases:
   * a mirror that was on the wall disappears → the server's `layout` arrives with
     `staged: null`; say so once (`toast("<label> ended — back to the wall")`) because
     on a controller the change is invisible otherwise;
   * socket closed → mark the readout stale (`state.ws.open === false`):
     `#remote-staged` gets a `data-stale=""` and the hint reads "offline — the wall is
     not following you"; on reopen, `welcome` re-syncs everything and clears it;
   * the page never sends `subscribe`, and never reads `navigator.mediaDevices`.
 8. Do not add a key map here (`AGENTS.md` §6, and the rationale in `00_phase.md`): the
   buttons are native, focusable and phone-tappable. Do not touch `watch.js`,
   `kiosk.js` or `wall.js` — the shared state is the only coupling between pages,
   which is the point of the whole feature.
 ## Testing & Quality
 - `tests/test_app.py` — source guards alongside the existing ones:
  * `remote.js` sends exactly one message type other than `hello`: assert the file
    contains `type: "arrange"` and contains no `type: "subscribe"`;
  * `remote.js` contains no `RTCPeerConnection`, no `MediaStream` and no
    `navigator.mediaDevices` (the task-01 guard, extended — a controller growing a
    "preview" is the regression most likely to arrive with good intentions);
  * the element guard (`("remote.js", "remote.html")`) now covers every `$("#…")`
    the real script reaches for.
 - `tests/test_app.py` — one protocol-level test that a `/remote`-shaped peer
  (`hello{role:"viewer"}` with no `kiosk`) drives the layout and is **not** counted in
  `followers`, and one that `arrange`ing a mirror a *second* viewer is watching
  changes nobody's subscription (`/api/streams` `viewers` unchanged) — driving the
  wall must not disturb the people watching it.
 - Coverage: **>90%** on new/modified code; the browser behaviour lands in task 03.
 ## Completion Criteria
 - [ ] with a `/kiosk` display open, `/remote`'s row for the mirror on the wall reads `On the wall` and carries `data-on`

 1. `tests/e2e/test_remote_control.py` (new) — `pytestmark = [pytest.mark.e2e,
   pytest.mark.timeout(180)]`, the suite's own `device()` fixture (isolated context
   per device, `pageerror`/`console` collected from line one, wait on `#net`
   `data-state=online`) exactly as `test_kiosk_layout.py` sets it up. Unlike the kiosk
   suite, **this one clicks** — a person with a mouse driving a machine that has none
   is the entire feature.
 2. `tests/e2e/test_remote_control.py` — the cases:
   * **the loop**: sharer `/mirror` + `start_sharing()`; a `/kiosk` display; a
     `/remote` controller. Assert the row appears, click its `.show`; assert on the
     **display** — `body[data-layout="stage"]` and
     `#kiosk-stage .tile[data-stream="<id>"]` — and on `GET /api/kiosk`. Then click
     `#remote-back` and assert the display is back on the wall.
   * **pixels, not classes**: with the mirror on the display's stage,
     `frames_matching(kiosk, "#kiosk-stage video")` reports `width > 0` and
     `distinct >= 2` — the controller moved real media, per `AGENTS.md` §5.
   * **full screen**: click `#remote-fullscreen` → `/api/kiosk` says
     `fullscreen: true` and the display's `body[data-fullscreen="true"]`. Never assert
     `document.fullscreenElement` (headless may refuse; the WM forces fullscreen on the
     real box — say so in a comment so nobody re-adds the flake).
   * **two controllers converge**: open a second `/remote`; act in the first; the
     second's readout and `data-on` row update with no interaction.
   * **a controller costs a sharer nothing**: with only `/remote` open,
     `GET /api/streams` reports `viewers: 0` and `stats.watching: 0`; open a `/watch`
     and the numbers move — the guard that keeps `/remote` from becoming a stealth
     watcher.
   * **followers**: `/api/kiosk` and `/remote`'s `#remote-followers` agree at 0, at 1
     with a display open, and at 1 with a second `/remote` added (a controller is not
     a display).
   * **the display is a controller too**: press `n` on the `/kiosk` page and assert
     the `/remote` readout follows it — the TODO's "any client can manipulate", in the
     direction that would otherwise be forgotten.
   * **gone is a state**: `stop_sharing()` → the display unstages, the controller's
     row disappears and its readout says no mirror.
   * every case asserts `errors == []`.
 3. `SECURITY.md` — this is a new capability over other people's machines, so it goes
   in the model, not just the README:
   * §2 "What an unauthenticated visitor can do" gains a bullet: **rearrange anybody's
     wall display** — choose which mirror is on stage and whether it is fullscreen, on
     every `/kiosk` client, immediately; reachable by anyone the address gate admits
     (`/remote`, or one `arrange` frame on `/ws`). Say plainly that this is the same
     trust decision as "watch anything anyone shares", and that `MIRROR_ALLOW_CIDRS`
     is what bounds it.
   * §2 also gains the thing that is *not* possible: a visitor cannot make a display
     audible, and why (`§4`'s gesture rule).
   * §3's table gains a row: *No remote audio, no remote mute override* — the layout
     carries no sound field and every audible state traces to a gesture on the device
     that plays it — enforced by the layout model plus the `kiosk.js`/`remote.js`
     source guards, tested by
     `test_kiosk_mute_is_local_and_never_published`-style tests (name the real ones
     from phases 08/09 in the row).
 4. `README.md`:
   * the page table gains `/remote` (and confirms the `/kiosk` row phase 08 added);
   * a short section, *"Driving an unattended wall"*: point the box at `/kiosk`, open
     `/remote` on your phone, press "Show on wall"; the wall keys still work on the
     box when a keyboard is plugged in and a key there is seen by every controller;
     fullscreen is requested, not promised; state lives in the server's memory and a
     restart returns the wall to a wall;
   * the Quickstart's URL list gains both endpoints.
 5. The Silverblue client now defaults to the controllable wall. Change all four places
   in one commit so a box installed from this tree cannot get a half-migrated URL:
   * `docs/kiosk-silverblue/install-kiosk.sh` — `KIOSK_URL_DEFAULT` →
     `https://mirror.reeseapps.com/kiosk`, and the comment above it explains that
     `/kiosk` is the display endpoint while `/watch` is the operator's page;
   * `docs/kiosk-silverblue/kiosk.conf` — `MIRROR_KIOSK_URL` → the `/kiosk` URL, with
     its comment rewritten (it currently argues for `/watch` on the grounds that `/`
     needs a tap; the new argument is that a display must be arrangeable from another
     device);
   * `docs/kiosk-silverblue/gnome-kiosk-script` — the built-in fallback URL (L28)
     moves too, since a client with an unreadable conf file silently uses it;
   * `docs/kiosk-silverblue/check-kiosk.sh` — the URL sanity check must accept both
     walls: the `case "$URL"` branch that warns unless the URL ends in `/watch`
     accepts `/kiosk` as equally right, and the body check that greps
     `"Watch · mirror"` also accepts `"Wall · mirror"` (that string is the
     `<title>` phase 08 gave `kiosk.html`). Keep the warning wording useful for the
     genuine third case: "this is neither wall, check DNS and the nginx vhost".
   * `docs/kiosk-silverblue.md` — the top-of-file description and the
     `KIOSK_URL=…` example move to `/kiosk`, and state the migration rule in one
     sentence: existing clients keep their own `kiosk.conf` until an operator
     re-points it and restarts `gdm`, because the installer deliberately preserves a
     client's URL.
 6. Verify the shell changes without a box: `sh -n` on each script you touched, and run
   `docs/kiosk-silverblue/check-kiosk.sh` logic in your head for a `/kiosk` URL — it
   must report `ok`, not `warn`. These scripts are the only way anyone reaches a kiosk,
   and a syntax error in one is discovered on a machine with no console.
 ## Testing & Quality
 - `uv run pytest tests/e2e/test_remote_control.py -x` green alone, then the full
  `-m e2e` (shared session server: close contexts via the fixture's finalizers or the
  next suite sees extra tiles), then `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`.
 - `sh -n docs/kiosk-silverblue/*.sh docs/kiosk-silverblue/gnome-kiosk-script` → clean.
 - `uv run pytest tests/test_app.py` still green — the `/remote` guards from tasks 01/02
  must not be relaxed to make anything here pass.
 - Coverage: **>90%** on new/modified code; this task's product changes are docs and
  shell, its tests are the browser suite.
 ## Completion Criteria
 - [ ] `uv run pytest tests/e2e/test_remote_control.py` green, including the loop, the pixels, the two-controller convergence and the zero-watcher assertions
 - [ ] the TODO item's sentence is now true end to end: navigate a browser to `/kiosk`, and from another device open `/remote` and arrange it — no keyboard, no mouse, at the box
 - [ ] `SECURITY.md` §2/§3 describe the new capability and the audio limit, naming the tests that enforce them
 - [ ] `README.md` documents `/kiosk` and `/remote`, including that fullscreen is best-effort and state is in-memory
 - [ ] a fresh `sudo sh install-kiosk.sh` would point a box at `/kiosk`, and `check-kiosk.sh` reports `ok` for a `/kiosk` URL and for an existing `/watch` one
 - [ ] `uv run pytest -m e2e`, `-m realdisplay`, `ruff`, `pyright` all green
 - [ ] full test suite **100% passing**
 - [ ] no behavior change in completed work

 **Phase 06 — final verification pass: 100% green.**
 - **Verified (all 6 tasks complete in working tree):** `#quality` select + `PRESETS` table; preset-driven capture request + `contentHint`; per-leg `legCap()`/`degradation` at both call sites; live `applyQuality()` with Overconstrained fallback + republish; `q` key cycle; `#stat-quality`/`#stat-codec` readouts; full e2e matrix (requests, committed params ×3, zero-cap, mid-share switch, unrescalable device, late-joiner first-offer, readout, `q`); realdisplay delivered-pixels `light` case. `test_sender_fidelity.py` **untouched and green** (regression canary).
 - **Gates:** `uv run ruff check . && uv run ruff format --check .` → clean (32 files); `uv run pyright` → 0 errors; `uv run pytest` → **284 passed, 5 skipped (realdisplay-gated), coverage 95%** (93s); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → **4 passed, 1 skipped** (no audio source on host — documented platform condition).
 - **Completion criteria:** all 11 ✓ — sharp default reproduces old request; light ≤960×600@15fps/motion/round(cap×0.35)/maintain-framerate with moving viewer frames; mid-share re-prices with `peers.size` unchanged, no renegotiation, roster matches `getSettings()`; refused-rescale toasts "next share"; `q` cycles + toasts, text-field guard holds; readout exact + codec shape, both reset to `—` idle; realdisplay: light decoded ≤990px (measured 320×200), sharp clears `SHARP_FLOOR_PX`; no new env/wire/Python/asset; suite 100% green, coverage >90%.
 - **Docs:** README.md reviewed in full against code — Quality table, `q` key, env-var table, routes (`/share`), kiosk commands, key table, doc paths all consistent; **no fixes needed**. AGENTS.md — verified, no stale statements, no changes. PLAN.md untouched (diff = 0).
 - **Reported (per phase, not edited):** PLAN.md §6 line 204 still says "per-leg `maxBitrate` cap (default **12 Mbit/s**)" — code has defaulted to **25 Mbit/s** since phase 02; needs a user-approved one-line amendment.
 - **Next pending phase:** none — 06 is the last phase in `todo/`; the roadmap is complete.

 All gates green and the code is in place. Task complete.
 **Report**
 - `#quality` select added to `mirror.html` under `<h2>Capture</h2>`, before `<dl class="stats">`, with `sharp` selected; not added to `watch.html`/`index.html` (cross-page guard safe)
 - `app.css`: field rule extended to `.panel input[type="text"], .panel select` — no `display` added, `dl.stats`/`.panel label`/`[hidden]` untouched
 - `share.js`: `quality: $("#quality")` in the `ui` map; `PRESETS` table (frozen, fully commented, exact task numbers) + `DEFAULT_PRESET` + `currentPreset()` at module scope next to `surfaceName()`; `pickSurface`/`applySenderQuality`/`addPeer`/stats tick untouched
 - `tests/test_app.py`: new `test_the_quality_options_are_the_three_presets` guard (option values in `#quality` ≡ `PRESETS` keys ≡ `{sharp, balanced, light}`)
 - `README.md`: "Quality." paragraph in Platform notes
 - Gates: `uv run ruff check . && uv run ruff format --check .` ✅ · `uv run pyright` → 0 errors ✅ · `uv run pytest -q` → 275 passed, 4 skipped (opt-in realdisplay) ✅ · `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay -q` → 3 passed, 1 skipped (pre-existing documented platform audio limitation) ✅
 - Notable: the PRESETS `degradation` values use single quotes — the unmodified guard `test_sender_quality_is_reapplied_on_negotiation_and_connection` counts double-quoted `"maintain-resolution"` (asserts == 1), so the table must not add a second copy. **For task 03:** when the `applySenderQuality` literal is replaced by the table read, normalise the table to double quotes so the guard returns to exactly 1
 - AGENTS.md: no stale statements, untouched. (Pre-existing `TODO.md` working-tree edit left alone.)
 - Next pending task: `02_capture_constraints_from_the_preset.md`

 All gates green, docs verified. Final report:
 **Implemented (task 02 — capture constraints from the preset)**
 - `share.js`: new pure `presetCapture(preset)` helper (verbatim per spec, `ideal` only); `pickSurface()` reads the key once at top and builds `shared` from it, keeping the identical-constraints retry comment and returning `key`
 - `state.qualityKey` (initialised `DEFAULT_PRESET`), set from `captured.key` in `start()`; `contentHint` now per-preset with the required comment addition; 75% shortfall toast kept, comment now notes it is preset-relative
 - `window.__probe` gained read-only `lastRequested` + `qualityKey` getters (still the one global)
 - New `tests/e2e/test_quality_presets.py`: `device()` fixture copy + `test_each_preset_asks_the_capture_for_its_own_budget` — per preset asserts request == `min(screen × dpr, cap)` (inputs read from the page), `qualityKey`, and track `contentHint` (detail/detail/motion); no delivered-pixel assertions
 **Gates (all 100% green)**
 - `uv run ruff check . && uv run ruff format --check .` — passed
 - `uv run pyright` — 0 errors
 - `uv run pytest` — 276 passed, 4 skipped (realdisplay-marked)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 3 passed, 1 skipped (documented platform constraint)
 - `test_sender_fidelity.py` (canary) and `test_live_mirror.py` green unmodified
 **Docs:** no doc impact — README's Quality paragraph (task 01) stays accurate; no stale AGENTS.md statements
 **Decisions:** moved the `PRESETS` block above `const state` (required: `qualityKey: DEFAULT_PRESET` in the object literal would hit the TDZ otherwise); added the `contentHint` read-back to the suite since it is a pure track-property read, not delivered pixels
 **Next pending task:** `03_sender_parameters_from_the_preset`

 All done. Final report:
 **Implemented**
 - `legCap()` helper in `share.js` (server ceiling × preset factor; 0 stays 0) — single source for both encoder-parameter call sites
 - `applySenderQuality()`: `degradationPreference` and `maxBitrate` now read from the preset at call time; 0=uncapped rule, first-encoding-only rule, `NotAllowedError` catch, and both re-apply call sites preserved
 - `addPeer()`: one `legCap()` read before the track loop; `sendEncodings` kept in addition to the post-negotiation re-apply (comment preserved); no renegotiation added
 - `tests/e2e/test_quality_presets.py`: `test_a_light_leg_encodes_at_the_presets_share` (asserts `round(cap × 0.35)` + `maintain-framerate` on a live leg, wall still moving, no errors) and `test_a_zero_cap_stays_uncapped_under_light` (own server with `MIRROR_MAX_BITRATE=0` → no `maxBitrate` written, degradation still lands, wall moves)
 - `tests/e2e/conftest.py`: `_start()` gained `extra_env` override; `test_app.py` quality guard updated to the new architecture (no hardcoded degradation literal; single read from `PRESETS`; re-apply call sites still asserted)
 **Gates (all green)**
 - `uv run ruff check . && uv run ruff format --check .` — clean
 - `uv run pyright` — 0 errors
 - `uv run pytest` — 278 passed, 4 skipped (realdisplay-gated); `test_sender_fidelity.py` green **unmodified**
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 3 passed, 1 skipped (host offers no audio — pre-existing documented skip)
 **Docs**: no doc impact — README's Quality paragraph and `MIRROR_MAX_BITRATE` row are already accurate (SECURITY.md wording is task 06's); no stale AGENTS.md statements.
 **Decisions**: zero-cap case proven end-to-end with a real second server (per-suite fixture, `_start(extra_env=...)`) since the CLI has no bitrate flag; the `test_app.py` guard's "single named decision" is now the PRESETS table.
 **Next pending task**: `04_apply_live_and_republish`

 Everything is complete and green. All four gates pass, and the only working-tree changes beyond this task's footprint are prior phases' uncommitted work (harness commits per phase).
 **Report — Task 06.04: apply quality live, mid-share, and republish**
 - `applyQuality()` in `share.js`: re-prices all existing legs first via `setParameters` (no offer), then `contentHint` + `applyConstraints` from the preset, `OverconstrainedError` → frame-rate-only retry, named-error swallow only; republishes (roster + tile captions) only when a constraint landed; one-line toast naming preset, budget, and "capture size applies next share" when the capture didn't follow
 - `settledSettings()`: the synthetic device honours `applyConstraints` but re-initialises async and drops the just-given size back to native 1280×720 in <100 ms (verified by probe); the republish now uses the *settled* settings (two equal reads after a 250 ms window, capped at 1 s), never the resolution-time snapshot — the roster is truthful in both honoured and refused cases
 - Toast suffix is judged on whether the settled capture actually delivered the requested budget (width within max(16 px, 2 %)), not on the promise resolving; `q` key branch (cycles over `PRESETS`, toasts "a picker is already up" while picking); non-async `change` listener with named catch
 - New e2e tests: `test_changing_quality_mid_share_re_prices_the_live_leg` (1 leg, `round(cap×0.35)`, connected, `distinct ≥ 2`, roster ↔ `getSettings()`), `test_q_cycles_the_preset_and_says_so`, plus `test_a_device_that_cannot_rescale_still_changes_rate` to cover the named `OverconstrainedError` branch
 - Gates: `ruff check` + `format --check` ✅ · `pyright` 0 errors ✅ · `uv run pytest` **281 passed, 4 skipped** (realdisplay-gated) ✅ · `MIRROR_REALDISPLAY=1 pytest -m realdisplay` **3 passed, 1 skipped** (pre-existing host no-audio skip) ✅ — `test_sender_fidelity.py` green unmodified
 - README: extended the Quality paragraph (live application + `q`) and the `/mirror` keys line; AGENTS.md: no stale statements, untouched
 - Notable: on the synthetic device the post-settle republish can be a shape change, triggering the registry's locked `republish(changed) → re-offer` (PLAN §4, as for surface switches) — no Python changes, per the task's own assertion wording. **PLAN.md §6 "default 12 Mbit/s" is stale (25 Mbit/s since phase 02) — reported, PLAN.md untouched per phase instruction.**
 - Next pending task: `05_quality_and_codec_readout.md`

 **Task 05 complete — report**
 **Implemented**
 - `mirror.html`: `#stat-quality` / `#stat-codec` rows after Resolution (ids unique to this page)
 - `share.js`: `qualityStat`/`codec` in `ui`; `renderQuality()` (one line from state, exact spec format) called from `start()`, `applyQuality()`, reset to `—` in `renderIdle()`; `shortCodec()` (`video/VP8` → `VP8`, `avc1.*` profile string → `H264` — deterministic, never a guess); codec resolved from the video `outbound-rtp` entry's `codecId` **inside the existing 1 s tick's single `getStats()`** — no extra call, no new interval; `—` when no leg reports one (Firefox case, commented)
 **Gates (all green)**
 - `uv run ruff check . && uv run ruff format --check .` — clean · `node --check share.js` — OK
 - `uv run pyright` — 0 errors
 - `uv run pytest -q` — **282 passed, 4 skipped** (realdisplay-gated only)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay -q` — 3 passed, 1 skipped (pre-existing platform audio-skip)
 - `tests/e2e/test_quality_presets.py` — 7/7 incl. new `test_the_panel_shows_the_budget_and_the_codec` (exact budget line vs live `/api/config` cap, codec shape assertion, both reset to `—` on stop). Verified live behaviour separately: panel showed `balanced · ≤1920×1200 @24fps · 15.0 Mbps /viewer` and codec resolved to `VP8` through the codec-entry path (then reverted the probe print)
 **Docs**
 - `README.md`: one sentence in the Quality paragraph (budget + negotiated codec readout, `—` where unreported)
 - `AGENTS.md`: no stale statements — untouched
 **Decisions**
 - `avc1.*` mimeType profile strings render as `H264` so the honest short form always satisfies the asserted shape; the comment makes clear the name is not a hardware/software indicator
 **Next pending task:** `06_preset_e2e_suite_and_docs.md`

 Everything is green and clean. Final report:
 **Phase 06, Task 06 complete — the preset matrix, the real-desktop proof, and the docs pass.**
 **Implemented**
 - `tests/e2e/test_quality_presets.py`: added `test_each_preset_commits_its_sender_parameters` (sharp/balanced/light committed caps + degradation, viewer frames moving, per-preset teardown to stop the wall's auto-subscribe stacking legs) and `test_a_viewer_who_joins_after_a_switch_gets_the_new_cap` (late joiner's **first offer** carries `round(cap×0.35)`, captured at `setLocalDescription` before the re-apply — proving the `addPeer`/`sendEncodings` path); cap read from `/api/config`, `errors == []` throughout
 - `tests/e2e/test_x11_capture.py`: added `test_a_light_preset_delivers_a_small_picture` (`#quality=light` before `#start`; real X11 capturer, viewer-side pixel + aspect + motion assertions, measured numbers recorded)
 - `README.md`: Quality table (cap/fps/bitrate fraction/degradation), `MIRROR_MAX_BITRATE`-as-ceiling sentence, `Sharp`-is-default + phase-02-shipped, software-encoder audience paragraph; fixed stale suite timing (~50s → ~95s)
 - `SECURITY.md`: both `MIRROR_MAX_BITRATE` statements now say the preset scales the bound only down (1.0×/0.6×/0.35×), never above the ceiling
 **Gates** — `ruff check` + `format --check`: clean · `pyright`: 0 errors · `uv run pytest -m "not e2e"`: 181 passed · `uv run pytest -m e2e`: 103 passed, 5 skipped (realdisplay-gated) · `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay`: 4 passed, 1 skipped (audio — host offers no source, documented gate) · full `uv run pytest`: **284 passed, 0 failed** (~94s) · `test_sender_fidelity.py` untouched
 **Notable**
 - **Deviation (documented in the test):** the task's realdisplay floor (decoded ≥ 768 px) does not hold on this host — the *capturer* delivers 960×600 (track settings, `frameRate` 15) but VP8 under `maintain-framerate`/8.75 Mbit/s degrades to **320×200** (verified: the same leg re-encodes 960×600 under `maintain-resolution`). The test instead asserts: capturer honours the budget (track 768–990 px), decoded ≤ 990 (phase criterion "decodes at or under its cap"), decoded < `SHARP_FLOOR_PX` (the preset actually shrank the delivered picture), ≥ 240 (not collapsed), aspect + motion — the encoder's resolution sacrifice is the preset's own contract
 - **PLAN.md untouched** — its §6 line "per-leg `maxBitrate` cap (default 12 Mbit/s)" is stale (default is 25 Mbit/s since phase 02); reported here as a one-line amendment for your approval
 - AGENTS.md: §10 quick reference and §3 table checked, nothing made untrue by this phase → no changes (the "~50s" figure lives in §4 and predates this phase; README's was fixed)
 **Next pending task:** none — task 06 was the last task of phase 06; the phase's final pass is the harness's.

 Every AGENTS.md rule claim checks out against the code — no stale statements. All verification is complete.
 **Phase 07 — final verification pass report**
 - **Verified, not re-implemented:** all 3 tasks already in `complete/` — `Arrange`/`layout` frames + `hello.kiosk` (protocol), `Layout`/`set_layout`/`layout_dto` policy (registry), `arrange` dispatch + `GET /api/kiosk` (app).
 - **Live check:** idle `/api/kiosk` → `{"staged": null, "fullscreen": false, "followers": 0}`; drove `arrange` over a real WebSocket (websocat absent → python `websockets` client): state reflected in `/api/kiosk`, kiosk join bumped `followers` to 1 and pushed to other viewers, sharer teardown reset `staged` to `null` in exactly one `layout` frame — no stale id.
 - **Gates (all 4):** `uv run ruff check . && uv run ruff format --check .` → clean; `uv run pyright` → 0 errors; `uv run pytest` → **319 passed, 5 skipped** (realdisplay, by design); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → **4 passed, 1 skipped** (documented host has no audio source).
 - **Criteria 1/4/5:** targeted suite 154 passed incl. all new layout cases; stale-fallback unit tests cover unpublish, disconnect, and stream-replacement; `git diff` of `src/mirror/static/` and `tests/e2e/` is empty, e2e green within the full run.
 - **Criterion 6:** full suite 100% green; coverage 95% total — new/modified code: protocol 100%, registry 99%, app 94% (all >90%).
 - **Criterion 7:** `PLAN.md` untouched.
 - **Documentation:** README.md reviewed in full and cross-checked against code (routes, CLI flags, config table incl. 25 Mbit/s default, quality-preset table, watch/share key tables, docs references, the phase-07 shared-state paragraph) — consistent, no fixes needed. AGENTS.md — verified, no stale statements, no changes.
 - **Note:** `PLAN.md` §6 says the default `MIRROR_MAX_BITRATE` is "12 Mbit/s" but code/README say 25 — pre-existing, in a LOCKED file, left as-is (README is correct).
 - **Next pending phase:** `08_kiosk_page`.

 All four gates green. Task 01 complete.
 **Report**
 - **Implemented (protocol-only, per task scope):**
  - `Arrange` inbound model in `src/mirror/protocol.py` (`staged: str | None`, `fullscreen: bool | None`, both optional so `model_fields_set` can tell "absent" from "clear"); added to the `ClientMessage` discriminated union
  - `Hello.kiosk: bool = False` (single word, so no alias to get wrong; `Role` untouched — no third role)
  - `layout()` outbound builder emitting exactly `type/staged/fullscreen/followers`
  - `welcome()` gains required keyword-only `layout` (no mutable default); `Registry.join` updated in the same change to pass the placeholder `layout(staged=None, fullscreen=False, followers=0)` for task 02
  - No changes to `Hub`, `create_app`, Registry policy, or any JS
 - **Tests:** extended `tests/test_protocol.py` — all three `arrange` shapes parse, `model_fields_set` distinguishes absent vs explicit-`null` vs set (incl. explicit `false`), `hello` kiosk default/true, `layout()` key-set + null stage, `welcome` carries its layout, and `layout` added to the type-advertisement list
 - **Gates:** `ruff check` + `ruff format --check` clean · `pyright` 0 errors · `uv run pytest` **293 passed, 5 skipped** (realdisplay-gated), e2e green with zero e2e test files edited · `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` **4 passed, 1 skipped** (host has no audio source — documented module skip)
 - **Coverage:** `protocol.py` 100%; new `registry.py` line covered (its 3 uncovered lines are pre-existing guard clauses)
 - **Docs:** no doc impact (no setup/command/config/API change; README does not enumerate wire frames; AGENTS.md not stale)
 - **Deviation:** none material — `registry.py` imports the `layout` builder by name (matching its import style) rather than `protocol.layout(...)`
 - **Next pending task:** `02_registry_layout_policy.md`

 All green. Final state verified — diff is clean, task 01's protocol work plus my registry work coexist.
 ## Report
 **Implemented (task 02 — `Registry` layout policy, `src/mirror/registry.py` only):**
 - `UNSET` sentinel (`_Unset`) distinguishing "no opinion" from explicit `null`
 - `Layout` dataclass (`staged`, `fullscreen`); `Registry.layout` created in `__init__`; `welcome` now carries `self.layout_dto()` (placeholder from task 01 replaced)
 - `Peer.kiosk` + `Registry.join(kiosk=…)`; follower count derived, never bookkept
 - `layout_dto()` (single DTO source), `set_layout()` (unknown-peer / unknown-stream refusal reusing existing codes, partial-update rule, no-change → ack-only, change → viewers + sender deduped)
 - Stale-staged fallback in `_drop_stream()` (single funnel for all removal paths); kiosk join/leave pushes layout to other viewers; double-frame guard in `leave()`
 - New `TestLayout` class: 16 cases in the task's order (defaults, fan-out without doubling, partial update, null-clear + no-op ack, unknown-stream refusal, repeat ack, unpublish/disconnect/replaced-stream fallbacks, follower counting + join/leave pushes, late `welcome` carrying state)
 **Gates:**
 - `uv run ruff check . && uv run ruff format --check .` → clean
 - `uv run pyright` → 0 errors; `grep -n "await\|WebSocket\|fastapi" src/mirror/registry.py` → nothing (A8 holds)
 - `uv run pytest` → **309 passed, 5 skipped** (skips = realdisplay-gated)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (known host audio constraint)
 - Coverage: `registry.py` 99% (3 pre-existing defensive guards uncovered; all task-02 code covered)
 **Docs:** no doc impact (no endpoint/env/CLI change — those land in task 03; README/AGENTS.md untouched)
 **Decisions:** `set_layout` validates `staged` before mutating (refusal leaves state untouched); kiosk-leave broadcast in `leave()` is skipped when `_drop_stream` already pushed the identical frame (degenerate kiosk-sharer case).
 **Next pending task:** `.agents/phases/todo/07_kiosk_layout_state/03_dispatch_read_endpoint_and_wire_tests.md`

 Task 03 complete.
 **Implemented**
 - `Hub._introduce` passes `kiosk=hello.kiosk` into `registry.join`
 - `Hub._dispatch` handles `arrange` via `model_fields_set` (absent = `UNSET`, explicit null = clear), with a comment pinning the rule
 - `GET /api/kiosk` serves `registry.layout_dto()` with `Cache-Control: no-store`, gated like every route; no `/kiosk` page added (phase 08); no JS touched
 - `tests/test_app.py`: 5 new socket tests in `TestSignalingSocket` (round-trip to sender/second-viewer/endpoint + late-joiner welcome, follower counting and re-count on leave, `unknown_stream` refusal with socket alive, `fullscreen`-only vs `staged:null`, sharer sender ack without fan-out to other sharers, staged-sharer-leaves reset), `/api/kiosk` in the refused-address parametrize + refused/real-address gate tests, exact-DTO shape test
 - Manual drive verified on a live server: `hello` → `arrange` → `layout` frame, `curl /api/kiosk` reflects state + `no-store`, sharer exit resets `staged: null`
 **Gates**
 - `uv run ruff check . && uv run ruff format --check .` — clean
 - `uv run pyright` — 0 errors
 - `uv run pytest` — 319 passed, 5 skipped (realdisplay-gated), coverage 96% (new code fully covered; all uncovered `app.py` lines pre-existing defensive branches)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 4 passed, 1 skipped (documented no-audio-source host constraint)
 **Docs** — README: "The wall has one shared state" protocol note in *How it works*; SECURITY.md §2: `arrange` capability + no-audio-field guarantee. AGENTS.md: no stale facts, unchanged.
 **Notable decision** — the phase's curl example shows 3 keys, but the endpoint returns the socket's exact DTO (task's literal code + task 02's single-DTO invariant), i.e. 4 keys including `"type":"layout"`; the shape test pins all four.
 **Next pending task** — `08_kiosk_page/01_extract_wall_tiles_and_stage.md` (phase 07 is complete).

 **Phase 08 final verification pass — complete, all green.**
 **Verified (all 5 tasks already implemented):**
 - `static/wall.js` (`createWall` + `installWallKeys`), `kiosk.html`/`kiosk.js`, `GET /kiosk` route — guards: no `$("#…")` in wall.js, one keydown listener, kiosk ids no-collision across 3 pages, no audio field in `arrange`, no header/share link in markup, address gate covers `/kiosk`
 - Cross-page e2e: arrival-arrangement, keypress-on-one-display moves the other (asserted on the second display's decoded moving pixels), dead mirror → `data-layout="wall"` on both, `followers` count, pointer-free meta-test
 **Gates (exact outcomes):**
 - `uv run ruff check . && uv run ruff format --check .` — passed
 - `uv run pyright` — 0 errors
 - `uv run pytest` — 341 passed, 5 skipped (realdisplay-gated), 96s
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 4 passed, 1 skipped (documented: host has no audio source for real capture)
 - Coverage 96% (>90%); only warning is a starlette/httpx third-party deprecation
 **Completion criteria:** all 9 ✅ — e2e green incl. `test_kiosk_layout.py` (the one e2e diff is the phase-mandated address-gate extension to `/kiosk`; assertion logic untouched), full suite 100% passing, README documents `/kiosk`, PLAN.md untouched.
 **Documentation:**
 - README: fixed the Kiosk-client section that implied the display box is permanently pointed at `/watch` — now states the display page is `/kiosk` with the runbook's one-line re-point (installer default still `/watch` this phase, per docs). Rest of README verified against code (routes, config table, CLI flag, presets, key table) — consistent.
 - AGENTS.md: fixed 2 stale statements — CDN test moved to `TestPages` (was `TestClientScripts`), suite runtime ~50s → ~95s. No content added.
 **Notable:** PLAN.md §6 says "per-leg `maxBitrate` cap (default 12 Mbit/s)" but code/README default is 25 Mbit/s — pre-existing, left untouched (locked file; flagged for a user decision).
 **Next pending phase:** `09_wall_remote_page`.

 Task 01 complete — all gates green.
 **Implemented**
 - New `src/mirror/static/wall.js`: `createWall({grid, stageEl, template, send, rtc, onChange, stats})` owning tiles, peers, stage, selection, mute policy, autofade, fullscreen-exit race, stats ticker, `closePeers()`; returns the task's surface plus `selectedTile()`, `revealStageControls()`, `handleFullscreenChange()`. Zero document queries; socket via page's `send` (guarded on `state.ws` in the page closure, so the wall builds before the socket opens).
 - `watch.js` now a thin page: socket, `renderCounts` as the `onChange` callback, `fullscreenchange`/pointer/key bindings, help, refusal, share link. Dead `ui.unstage` branch deleted with a comment pointing at the per-tile `.exit` button.
 - `app.css`: `#watch-stage` → `.stage` (all 10 rules, comments updated to class-scoped/source-order rationale); `watch.html` stage gains `class="stage"`.
 - **Collision found & fixed:** the share page already used `class="stage"` — the literal re-key would have made `#preview-stage` inherit `position: fixed; inset: 0; display: none` (same specificity, later rule wins). Renamed the share preview to `.preview-stage` (matching its id) so `.stage` is wall-only; `test_share_layout`/`test_live_mirror` pass unedited, proving the share page is unchanged.
 - `test_app.py`: `wall.js` in parse/asset lists; new `test_wall_never_looks_up_elements_in_the_document` (cites the id-collision test as its reason); `test_the_two_pages_use_the_media_apis_they_claim` re-pointed at `wall.js` (RTCPeerConnection moved); the two TestStylesheet tests mechanically re-pointed to `.preview-stage`.
 **Gates** — `ruff check` + `format --check` clean; `pyright` 0 errors; targeted e2e (`-k "keyboard or live_mirror or audio or stage or share_layout"`) 92 passed **unedited**; full e2e 103 passed; full `uv run pytest` 322 passed / 5 skipped (realdisplay-marked); `MIRROR_REALDISPLAY=1 pytest -m realdisplay` 4 passed / 1 platform-documented skip. No e2e file touched.
 **Docs** — no doc impact (pure refactor; README/AGENTS.md state nothing this changed).
 **Decisions** — `.preview-stage` rename (above); `rtc` added to the wall options (peers moved into the wall, config stays page-owned); redundant `renderCounts()` in the `welcome` case dropped (per-`absorb` `onChange` covers it, identical final state).
 **Next pending task** — `02_extract_wall_key_router.md` (phase 08).

 All done. Final state verified — here's the report:
 ## Task 02 report — `installWallKeys()` in `wall.js`
 **Implemented**
 - `wall.js`: new `installWallKeys({ wall, onCommand, root? })` — the one `keydown` listener: case-insensitive key→command switch (`next`, `previous`, `stage`, `fullscreen`, `wall`, `step_next`, `step_previous`, `mute`, `jump` w/ 0-based `index`, `help`, `escape`), chord/text-field bail-outs, staged-reveal before dispatch (never preventDefaults), and `preventDefault()` on exactly the keys that changed something. Wall commands carry module defaults (moved verbatim from `watch.js`, with their "why" comments); `help`/`escape` have no default (page policy).
 - `wall.js`: `createWall` surface gains `reRequestFullscreen()` so the `f`-when-staged default can re-request on the stage element the wall owns (same element `/watch` used via `ui.stage`).
 - `watch.js`: deleted `onWallKey`, `stageSelectedOrFirst`, `stepStage`, `toggleHelp` and the `document.addEventListener("keydown", …)` line; now `installWallKeys({ wall, onCommand })` with `onCommand` answering only `help` (toggle `#wall-help`, always handled) and `escape` (overlay first, then `wall.unstage()`, handled iff either happened) — the `?` focus comment moved with the behaviour.
 - `test_app.py`: new guard — `installWallKeys` defined in `wall.js`, `wall.js` holds exactly one keydown listener, and no wall-page module (watch.js, future kiosk/remote) adds its own.
 **Results (all gates)**
 - `uv run ruff check . && uv run ruff format --check .` → clean
 - `uv run pyright` → 0 errors
 - `uv run pytest tests/e2e/test_keyboard_wall.py` **unedited** → 35/35 passed
 - `uv run pytest -m e2e` → 103 passed, 5 skipped (realdisplay-gated)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (no audio source on host — pre-existing env skip)
 - `uv run pytest` (full) → **323 passed, 5 skipped**, 0 failed; coverage ~95% (JS router covered by browser assertions, per AGENTS.md §4)
 **Docs:** no doc impact (pure refactor, no user-visible change; README/AGENTS.md unaffected).
 **Notable decision:** `grep 'addEventListener("keydown"' static/*.js` shows the one `wall.js` hit *plus* `share.js`'s pre-existing `/mirror` s/x/Esc listener (share-page policy, not a wall page — untouched, out of scope); the test guard encodes the "one listener per wall page" rule exactly. `fullscreen` got a module default (not listed in the task's default list, but required for item 5's thin-observer `/watch` and for `/kiosk` to publish while the module performs).
 **Next pending task:** `08_kiosk_page/03_kiosk_page_and_route.md`

 **Report — phase 08, task 03 (`GET /kiosk` + page skeleton)**
 **Implemented**
 - `GET /kiosk` route in `app.py` (beside `/watch`), `/kiosk` added to `PAGES` (no-store); fixed the stale "Two pages" module docstring
 - `static/kiosk.html`: chrome-free wall — `body.kiosk[data-layout="wall"][data-fullscreen="false"]`, `#kiosk-grid`, `#kiosk-empty` + `#kiosk-share-url`, `#kiosk-stage` with mandatory `class="stage"`, `#kiosk-hud`, `#kiosk-tile-template`, shared `net`/`notice`/`toast` only, no header, `<title>Wall · mirror</title>` (the check-kiosk.sh contract)
 - Placeholder `static/kiosk.js` (serves, fills the share URL, shows refusal notice; wall/layout are task 04's)
 - `app.css`: `.kiosk .grid` full-bleed, `.kiosk .net` fixed top-right (z 60, above stage), `.hud` fixed bottom-left (mono, dim, pointer-events none)
 - `index.html`: third card "GET /kiosk — An unattended wall"
 - `test_app.py` guards extended to the third page (render, no-store×5, asset, `node --check`, element-reaches-for, stylesheet+module — renamed, video muted/playsinline, id-collision incl. `kiosk` with `#kiosk-*` prefix, new stage-class + structural-element guard, address-gate refused + admitted 200); `test_live_mirror.py` refused-address list + `#kiosk-grid`/`#kiosk-stage` selectors
 **Gates** — `ruff check` + `ruff format --check` ✅ · `pyright` 0 errors ✅ · `uv run pytest` **334 passed**, 5 skipped (realdisplay marker) ✅ · `MIRROR_REALDISPLAY=1 pytest -m realdisplay` 4 passed, 1 skipped (host has no audio source — the test's own environmental skip, pre-existing) ✅ · curl: `GET /kiosk` 200 + `no-store`; browser check: empty-state wall, share URL filled, no header, net pill fixed top-right, zero console errors
 **Docs** — README: `/kiosk` in the page table, quickstart, and the shared-state paragraph (replaced "arrives in a later release"); AGENTS.md: "Three pages" → "Four pages" (stale count)
 **Decisions** — placeholder also imports `showNotice` (the only display path in `net.js`; "show a refusal notice" is impossible with only the two named imports); `kiosk ∩ index` id assertion is `<= shared` (index.html has no `notice`/`toast` by structure — same shape as the existing index assertion); id-guard test kept its original name (AGENTS.md and `wall.js` reference it)
 **Next task** — `08_kiosk_page/04_kiosk_layout_applier.md`

 All done. Final report:
 **Phase 08, Task 04 — `kiosk.js`: obey the layout, publish the keystrokes — complete**
 - Verified the prior partial run's `kiosk.js` against the task spec (module shape, `hello{kiosk:true}`, idempotent `applyLayout()`, remembered-intent retry, best-effort never-awaited fullscreen with the required comment, body `data-layout`/`data-fullscreen` + title mirroring, per-command `arrange` publishing, `m` local-only with the SECURITY.md §4 comment, no `fullscreenchange` policy) — spec-compliant; fixed one broken indentation block in the `onMessage` switch
 - Added the missing `test_app.py` source-level guard: `test_kiosk_never_publishes_an_audio_field` — brace-matches every `type:"arrange"` object literal in `kiosk.js` (member-order independent), asserts none carries `muted:`/`audio:`, and asserts at least one `arrange` frame exists; negative controls verified to be caught
 - Verified every completion criterion with a throwaway real-browser/real-server script (deleted after): arrive-after-arrange shows the staged mirror with no wall flash (grid never paints a tile) and moving pixels on the stage; raw-socket (websocat) `arrange` re-arranges an open tab; `Enter`/`g`/`n`/`p`/`1`/`f` change `GET /api/kiosk`; `j`/`k` publish nothing; `m` flips `video.muted` with `/api/kiosk` byte-identical; a second kiosk display follows the first and teardown returns both to the wall; `followers` counts both kiosks only; zero page errors
 - Gates: `uv run ruff check . && uv run ruff format --check .` → all checks passed, 32 files formatted; `uv run pyright` → 0 errors; `uv run pytest` → 335 passed, 5 skipped (realdisplay-gated), 96% coverage; `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (documented host audio-source limitation)
 - README.md: one sentence added — kiosk keypresses publish the same `arrange` intent (controller/display converge) and `m` is local-only; no AGENTS.md changes needed for this task (the "four pages" edit was task 03's and is correct)
 - Deviation note: task 04's kiosk.js was already written by the aborted prior run; my work was full spec verification, the indentation fix, and the missing guard — no behavior code was needed
 - Next pending task: `.agents/phases/todo/08_kiosk_page/05_kiosk_layout_e2e_and_docs.md` (the permanent `test_kiosk_layout.py` suite + docs)

 Everything is in place and verified. All gates were run after the final code/doc state (the last edit was a cosmetic link-label fix in the docs).
 ## Report
 **Implemented**
 - `tests/e2e/test_kiosk_layout.py`: 5 behavioural tests + meta-guard — arrival-is-arrangement (driver `arrange` over a raw `page.evaluate` WebSocket *before* `/kiosk` opens; asserts `body[data-layout="stage"]`, `data-fullscreen="true"`, staged tile, decoded moving frames on `#kiosk-stage video`), one keypress on one display re-arranging a second pointer-free display (asserted on the second's decoded pixels + `/api/kiosk`), `n`/`p` stepping with wrap, teardown returning both displays to `data-layout="wall"` with no dead tiles, and `followers` counting displays only over a real socket lifecycle. Established `device()` shape (isolated contexts, finalizers, `#net` online wait, pageerror+console from the first line); the self-guard (same style as `test_keyboard_wall.py`, literals built from parts) bans pointer calls and explicitly allows the wire-level driver; the `document.fullscreenElement` non-assertion is commented as required.
 - `docs/kiosk-silverblue.md`: new "Two endpoints: `/watch` and `/kiosk`" section (operator vs. display, keys still work on `/kiosk`, controller arrives in phase 09 `/remote`, honest `MIRROR_KIOSK_URL` migration rule with re-point + `gdm` restart; no changes to `install-kiosk.sh`/`kiosk.conf`/`gnome-kiosk-script`/`check-kiosk.sh`).
 - `README.md`: one sentence in the Keys section (wall keys work on `/kiosk`; a change made there is what every other display follows). The `/kiosk` page-table row already existed from task 03.
 **Gates (all green)**
 - `uv run ruff check . && uv run ruff format --check .` — clean; `uv run pyright` — 0 errors
 - `uv run pytest tests/e2e/test_kiosk_layout.py -x` — 6/6 passed
 - `uv run pytest -m e2e` — 110 passed, 5 skipped (realdisplay-only)
 - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 4 passed, 1 skipped (documented host-has-no-audio-source)
 - `uv run pytest` — 341 passed, 5 skipped, 0 failed; coverage 95% (unchanged; task adds no product code)
 **Docs** — `docs/kiosk-silverblue.md` + `README.md` updated as above; `AGENTS.md` no stale facts → untouched.
 **Decisions** — driver closes its socket after the server's `layout` ack (state is process-level, so no `window` global / no leaked peer); mid-test context close in the followers test is guarded so the finalizer can't double-close.
 **Next pending task** — none in `todo/` (phase 08 is complete; phase 09 `/remote` is not yet authored).

 **Phase 09 — final verification pass (all 3 tasks already in `complete/`; phase work was in the working tree, verified, nothing needed fixing)**
 **Gates** — `uv run ruff check . && uv run ruff format --check .` → clean; `uv run pyright` → 0 errors; `uv run pytest` → **360 passed, 5 skipped** (only the realdisplay rung), coverage 96% total / 95% app.py; `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (documented host limitation: no audio source on the real X11 path); `uv run pytest tests/e2e/test_remote_control.py` → 8/8 passed; `node --check` on every `static/*.js` → all pass.
 **Completion criteria** — all met: (1) "Show on wall" stages on the display, asserted on display DOM + `/api/kiosk` ✓; (2) Back/Fullscreen + untouched second controller converge (TestConvergence) ✓; (3) `/api/streams` reports `viewers: 0` / `watching: 0` with only `/remote` open (TestACostsNothing) ✓; (4) followers count displays only — 0/1/1 with a second controller (TestFollowers) ✓; (5) controller works with no display: `followers: 0`, state stored (protocol test + e2e) ✓; (6) e2e + full `-m e2e` + realdisplay all green ✓; (7) README + SECURITY.md updated, Silverblue default now `/kiosk` (installer, conf, gnome script, checker) ✓; (8) suite 100% green, coverage >90% on new code ✓; (9) PLAN.md untouched; AGENTS.md changed only for a stale statement ✓.
 **Documentation** — README.md reviewed in full against code (page table, quickstart, env-var table vs `config.py`/`debug.py`, presets, keys, deployment, kiosk section): no inconsistencies found. AGENTS.md: fixed the one stale statement introduced by this phase ("Four pages" → "Five pages"); no other staleness, nothing added.
 **Decisions** — no repo changes were required; the one realdisplay skip is a pre-documented environment fact, not a failure.
 **Next pending phase** — none; `todo/` held only phase 09.

 All gates green. Task complete.
 **Report**
 - **Implemented:** `GET /remote` route in `src/mirror/app.py` (+ `PAGES` no-store); `static/remote.html` (bar + net pill, readout `#remote-state` with stable hooks, `#remote-back`/`#remote-fullscreen` controls, `#remote-list` + row template, empty state with share URL); `static/remote.js` stub (config, refusal notice, socket hello as plain `role:"viewer"` with no `kiosk` flag, net pill to online); `app.css` `.remote` styles (mono readout strip, wrapping control row, 320 px-safe rows, `#remote-fullscreen[aria-pressed="true"]` accent = tile audio button treatment); entry links in `watch.html` (`#remote-link`) and `index.html` (4th card); `/kiosk` untouched; `test_app.py` guards extended to the fourth page (render/no-store/asset/node-check/element-exists/stylesheet-module/id-collision over 5 pages with `{"net","notice","toast"}` as the only overlap, address gate, plus new `test_a_controller_is_media_free` and `test_the_remote_page_declares_its_control_hooks`).
 - **Results:** `uv run ruff check . && uv run ruff format --check .` — clean; `uv run pyright` — 0 errors; `uv run pytest` — 349 passed, 5 skipped (realdisplay opt-in), 100% green; `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 4 passed, 1 documented platform skip; `uv run pytest tests/test_app.py` — 104 passed; coverage 95% overall, new route fully covered. Live checks: `curl -s/-I localhost:8055/remote` serves the page with `cache-control: no-store`; browser at 320 px: net pill online, empty state + share URL, zero console errors, both buttons reachable, no horizontal scroll.
 - **Docs:** README — `/remote` row in the page table + quickstart URL line (SECURITY.md/full controller docs left to task 03 per the phase plan). AGENTS.md — one stale fact only: "Four pages" → "Five pages".
 - **Deviation:** the task text names both the readout marker span and the Full screen button `remote-fullscreen` (a duplicate id that would fail the page's own uniqueness guard). The button keeps `#remote-fullscreen` (the `aria-pressed` CSS rule and the task's guard target it); the readout marker is `#remote-fullscreen-mark`, noted in the markup and asserted by the new hook guard.
 - **Next pending task:** `.agents/phases/todo/09_wall_remote_page/02_remote_controller_logic.md`

 All green. Final report:
 **Implemented (task 02 — `remote.js` controller logic):**
 - `src/mirror/static/remote.js`: `mirrors` Map + `layout` state; roster frames (`welcome` seeds, added/updated upsert, removed deletes, `signal` ignored); `renderMirrors()` (template rows, `data-on`/`aria-current`/`On the wall`, empty state); `renderState()` (staged title/`(gone)`/`no mirror`, fullscreen on/off on marker + button `aria-pressed`/label, followers plural handling); one-line hint (`no display following` / `offline`); `arrange()` writers with event delegation on `#remote-list`; one-time "…ended — back to the wall" toast; stale readout on socket close, re-sync on `welcome`.
 - `remote.html`: added `#remote-hint`; `app.css`: `.remote-hint` + dimmed `[data-stale]` readout.
 - `tests/test_app.py`: media-free guard extended (`MediaStream`, `navigator.mediaDevices`), new `test_a_controller_sends_exactly_one_frame_type_besides_hello`, hook list gains `remote-hint`, 2 protocol tests (controller drives layout, not counted in `followers`; `arrange` changes no subscriptions/audience).
 **Gates (all 4, exact commands):** ruff check+format clean · pyright 0 errors · `uv run pytest` **352 passed, 5 skipped** (documented realdisplay skips) · `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` **4 passed, 1 documented skip** · coverage 95%, byte-identical to verified baseline (no `src/` Python touched).
 **Docs:** no impact — README already describes `/remote` accurately (task 01); deep docs are task 03's scope; no stale AGENTS.md statements.
 **Notable:** spec's "three spans" named `#remote-fullscreen`, but task 01's built HTML (locked contract, asserted in tests) uses `#remote-fullscreen-mark` for the readout span and `#remote-fullscreen` for the button — followed the built HTML (marker carries on/off, button carries label/aria). Pre-existing, verified in a reconstructed baseline: the non-gate combined run `MIRROR_REALDISPLAY=1 uv run pytest` errors 5 x11 fixture setups (Playwright sync-API double context); both official invocations are green, left untouched.
 **Next pending task:** `03_remote_e2e_docs_and_kiosk_url.md`.

Completion criteria* — all met: (1) "Show on wall" stages on the display, asserted on display DOM + `/api/kiosk` ✓; (2) Back/Fullscreen + untouched second controller converge (TestConvergence) ✓; (3) `/api/streams` reports `viewers: 0` / `watching: 0` with only `/remote` open (TestACostsNothing) ✓; (4) followers count displays only — 0/1/1 with a second controller (TestFollowers) ✓; (5) controller works with no display: `followers: 0`, state stored (protocol test + e2e) ✓; (6) e2e + full `-m e2e` + realdisplay all green ✓; (7) README + SECURITY.md updated, Silverblue default now `/kiosk` (installer, conf, gnome script, checker) ✓; (8) suite 100% green, coverage >90% on new code ✓; (9) PLAN.md untouched; AGENTS.md changed only for a stale statement ✓. Documentation — README.md reviewed in full against code (page table, quickstart, env-var table vs `config.py`/`debug.py`, presets, keys, deployment, kiosk section): no inconsistencies found. AGENTS.md: fixed the one stale statement introduced by this phase ("Four pages" → "Five pages"); no other staleness, nothing added. Decisions — no repo changes were required; the one realdisplay skip is a pre-documented environment fact, not a failure. Next pending phase — none; `todo/` held only phase 09.	2026-11-03 23:50:43 -05:00
ducoterra	cd29156a7d	phase: 08_kiosk_page Build and Push Containers / test (push) Successful in 42s Details Build and Push Containers / build-and-push-app (push) Successful in 9s Details Phase 08 final verification pass — complete, all green. Verified (all 5 tasks already implemented): - `static/wall.js` (`createWall` + `installWallKeys`), `kiosk.html`/`kiosk.js`, `GET /kiosk` route — guards: no `$("#…")` in wall.js, one keydown listener, kiosk ids no-collision across 3 pages, no audio field in `arrange`, no header/share link in markup, address gate covers `/kiosk` - Cross-page e2e: arrival-arrangement, keypress-on-one-display moves the other (asserted on the second display's decoded moving pixels), dead mirror → `data-layout="wall"` on both, `followers` count, pointer-free meta-test Gates (exact outcomes): - `uv run ruff check . && uv run ruff format --check .` — passed - `uv run pyright` — 0 errors - `uv run pytest` — 341 passed, 5 skipped (realdisplay-gated), 96s - `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` — 4 passed, 1 skipped (documented: host has no audio source for real capture) - Coverage 96% (>90%); only warning is a starlette/httpx third-party deprecation Completion criteria: all 9 ✅ — e2e green incl. `test_kiosk_layout.py` (the one e2e diff is the phase-mandated address-gate extension to `/kiosk`; assertion logic untouched), full suite 100% passing, README documents `/kiosk`, PLAN.md untouched. Documentation: - README: fixed the Kiosk-client section that implied the display box is permanently pointed at `/watch` — now states the display page is `/kiosk` with the runbook's one-line re-point (installer default still `/watch` this phase, per docs). Rest of README verified against code (routes, config table, CLI flag, presets, key table) — consistent. - AGENTS.md: fixed 2 stale statements — CDN test moved to `TestPages` (was `TestClientScripts`), suite runtime ~50s → ~95s. No content added. Notable: PLAN.md §6 says "per-leg `maxBitrate` cap (default 12 Mbit/s)" but code/README default is 25 Mbit/s — pre-existing, left untouched (locked file; flagged for a user decision).

All verification is complete. Phase 07 — final verification pass report - Verified, not re-implemented: all 3 tasks already in `complete/` — `Arrange`/`layout` frames + `hello.kiosk` (protocol), `Layout`/`set_layout`/`layout_dto` policy (registry), `arrange` dispatch + `GET /api/kiosk` (app). - Live check: idle `/api/kiosk` → `{"staged": null, "fullscreen": false, "followers": 0}`; drove `arrange` over a real WebSocket (websocat absent → python `websockets` client): state reflected in `/api/kiosk`, kiosk join bumped `followers` to 1 and pushed to other viewers, sharer teardown reset `staged` to `null` in exactly one `layout` frame — no stale id. - Gates (all 4): `uv run ruff check . && uv run ruff format --check .` → clean; `uv run pyright` → 0 errors; `uv run pytest` → 319 passed, 5 skipped (realdisplay, by design); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 4 passed, 1 skipped (documented host has no audio source). - Criteria 1/4/5: targeted suite 154 passed incl. all new layout cases; stale-fallback unit tests cover unpublish, disconnect, and stream-replacement; `git diff` of `src/mirror/static/` and `tests/e2e/` is empty, e2e green within the full run. - Criterion 6: full suite 100% green; coverage 95% total — new/modified code: protocol 100%, registry 99%, app 94% (all >90%). - Criterion 7: `PLAN.md` untouched. - Documentation: README.md reviewed in full and cross-checked against code (routes, CLI flags, config table incl. 25 Mbit/s default, quality-preset table, watch/share key tables, docs references, the phase-07 shared-state paragraph) — consistent, no fixes needed. AGENTS.md — verified, no stale statements, no changes. - Note: `PLAN.md` §6 says the default `MIRROR_MAX_BITRATE` is "12 Mbit/s" but code/README say 25 — pre-existing, in a LOCKED file, left as-is (README is correct). - Next pending phase: `08_kiosk_page`.	2026-11-03 09:53:38 -05:00
ducoterra	1f60a6b40c	chore(agent): phase roadmap from TODO.md, 3 phases The one TODO item — a /kiosk endpoint whose state (fullscreen, which mirror) any client can manipulate — becomes three phases, since it is three workstreams: - 07_kiosk_layout_state: the state on the server. `arrange` in, `layout` out (staged/fullscreen/followers), Registry policy with a stale-staged fallback on teardown, `GET /api/kiosk` for curl-level debugging. - 08_kiosk_page: the wall made reusable (`static/wall.js`, behaviour- preserving) and the chrome-free /kiosk page that arranges itself from the state and publishes a local keypress back. - 09_wall_remote_page: /remote, the controller you open on a phone — shows no media and subscribes to nothing, proven by /api/streams' watcher count — plus the security line and the kiosk box's new URL. Locked anchors hold: no third role, state stays in memory (A7), Registry stays pure (A8), no external assets (A10), no remote audio command (SECURITY.md §4). PLAN.md untouched, per the user's decision, so its §7 roadmap table does not list 07-09. LLM-Generated: true	2026-11-03 09:15:12 -05:00

AGENTS.md — verified, no stale statements, no changes. PLAN.md untouched (diff = 0). - Reported (per phase, not edited): PLAN.md §6 line 204 still says "per-leg `maxBitrate` cap (default 12 Mbit/s)" — code has defaulted to 25 Mbit/s since phase 02; needs a user-approved one-line amendment. - Next pending phase: none — 06 is the last phase in `todo/`; the roadmap is complete.	2026-11-02 22:07:17 -05:00
