feat: phases 77–80 — navbar view refresh, static background, API tokens, history suggestion chips

Single consolidated commit for four completed, validated phases (77, 78,
79, 80). The pipeline run left all work uncommitted because the harness
commits only with PHASE_COMMIT=1 while child executors are forbidden from
committing; the phases themselves all passed validation and moved to
.agents/phases/complete/.

Phase 77 — navbar view refresh
- router.js dispatches bor:view-refresh on re-show / active re-click /
  popstate (gated on wasMounted; first show and boot exempt)
- History / RAG / Sources / Tuning re-fetch on refresh (admin branch);
  Chat deliberately excluded (stream survival)
- History "Refresh" button (admin-only, in-flight disable + status line)
- New story suite tests/e2e/test_navbar_refresh.py (7 tests)

Phase 78 — static background
- Removed the animated glow layers; static 44px grid over the flat --bg
  canvas; default and reduced-motion renders byte-identical
- Updated background/theme E2E suites; removed bg-glow test pins

Phase 79 — API tokens
- api_tokens model + migration 0012; hash-only token service
- Admin tokens API + Tokens admin view; POST /api/token-auth;
  live-revoking require_user on chat / suggestions / document content
- Frontend token gate with localStorage cache; anonymous E2E suites
  migrated to token login
- New story suite tests/e2e/test_api_tokens.py (9 tests)

Phase 80 — history suggestion chips
- last_questions() endpoint with SEED fallback; startNewChat() refetch
- Seed-semantics docs (config.py, .env.example, README)
- Integration state matrix + E2E suite rewritten to the 4 chip states

Also included: phase-76 report artifacts and the repo restore-test-db
skill (previously untracked), scripts/* ruff fixes from phase 77.

Final gate state (phase 80 final pass, covers everything above):
- uv run pytest --cov=app → 1637 passed, 0 failed, app/ coverage 99%
- uv run ruff check . && uv run pyright → clean, 0 errors
- Per-phase story E2E suites green in isolation

+generate and hand out so people can log in to use the app. The only
+thing that should be accessible without an API token is shared chats.
+The web ui should ask for a token before letting a user through and
+should cache that token in browser storage so they don't have to keep
+entering it."
+
+Run in isolation (DB must be up: ``podman compose up -d db``):
+
+    uv run pytest tests/e2e/test_api_tokens.py -v --no-cov
+
+Test → claim mapping (every clause of the owner's sentence is pinned):
+
+1. ``test_anonymous_is_locked_out`` — "ask for a token before letting a
+   user through": a fresh context meets ``#auth-gate`` on the chat
+   page, ``#main`` is inert (the composer is NOT keyboard-reachable —
+   the inverted tab-order walk), and the three gated endpoints
+   (chat / suggestions / document content) 401 from the context's own
+   empty cookies.
+2. ``test_shared_chats_stay_open_anonymous`` — "the only thing that
+   should be accessible without an API token is shared chats": the
+   admin creates + shares a saved chat (the house API pattern), a
+   FRESH context opens ``/shared/<token>`` anonymously and sees the
+   conversation rendered — no gate anywhere on that page.
+3. ``test_admin_generates_token_in_ui`` — "the admin can generate":
+   the admin navigates to the Tokens view, labels a token
+   "e2e-alice" and generates — ``#token-once-value`` carries
+   ``bor_`` + 32 hex (the A4 plaintext-once), the table shows the
+   Active row, and the once-block is GONE on a re-show (the plaintext
+   can never be re-shown).
+4. ``test_token_user_uses_the_app`` — "hand out so people can log in
+   and use the app": a fresh context signs in through the real gate
+   (the task-04 ``login_with_token`` helper), chats end-to-end
+   (mock LLM), opens a cited document in the same-page modal, and
+   gets the role-``user`` header contract — every admin nav link
+   absent, Sign out visible.
+5. ``test_cached_token_survives_reload`` — "cache that token in
+   browser storage so they don't have to keep entering it": the
+   entered token lands in ``localStorage["bor.token"]``; a reload
+   re-auths silently — no gate, no re-entry, still role user.
+6. ``test_admin_only_walls_403_for_token_user`` — "every existing
+   admin-only surface stays admin-only": the token user's own session
+   cookie 403s on tokens / chats / docs / steering / git-sources.
+7. ``test_sign_out_clears_the_cached_token`` — sign out clears the
+   session AND the cached token (one logout, both gone); the gate
+   comes back.
+8. ``test_revocation_closes_the_door`` — "revocation is enforced
+   IMMEDIATELY": the admin revokes through the UI two-step; the
+   holder's next gated request 401s (the 401 clears the dead
+   session cookie — the next whoami is anonymous), and a FRESH login
+   attempt with the same token is refused at the gate.
+9. ``test_wrong_token_is_one_generic_error`` — no enumeration: a
+   wrong token shows the gate's role=alert line and keeps the
+   visitor anonymous; the API's error body for a malformed token is
+   byte-equal to the one for a well-formed unknown token.
+
+DB isolation: the shared e2e Postgres keeps ``api_tokens`` (and
+``saved_chats``) rows across suites. This file is the only suite that
+issues tokens, so an autouse fixture deletes the ``e2e-``-labeled
+rows before each test (never a TRUNCATE — the shared DB may hold the
+owner's real tokens); the shared-chat test deletes its own saved row
+in a ``finally``. Every scenario runs in its OWN fresh browser
+context — no cached token (localStorage) or session cookie leaks
+between tests.

-"""Phase 22 E2E (Playwright): the background layers — now a regression
-suite for the phase-25 no-motion design.
-
-Story: ``.agents/user_stories/background-no-motion.md`` (the phase-25
-owner direction supersedes this suite's original pins; the phase-22
-history lives in ``.agents/user_stories/background-animation.md``)
-Run in isolation (DB must be up: ``podman compose up -d db``):
-
-    uv run pytest tests/e2e/test_background_animation.py -v --no-cov
-
-Phase 22 proved the phase-08 background (grid drift + whole-layer
-breathe) actually animated in a real Chromium viewport. The owner then
-reported (2026-08-25, chat): the background "jitters down and to the
-right every second and it slowly blinks brighter and darker. It should
-be smooth, fluxuating, dimming and brightening, but not moving.
-Different bright spots should slowly fade in and out." — so the
-phase-25 redesign (``frontend/assets/styles.css``) removed the
-movement entirely: the grid (``body::before``) is a STATIC texture
-(``bg-grid-drift`` deleted), and three independent soft glow spots run
-their own slow opacity-only fades — ``body::after`` runs ``bg-glow-a``
-(26s), ``html::before`` runs ``bg-glow-b`` (34s, −12s delay),
-``html::after`` runs ``bg-glow-c`` (42s, −23s delay).
-
-This adapted suite now pins the phase-25 contract on the same
-layers (the full story gate is
-``tests/e2e/test_background_no_motion.py``): the grid is static, the
-indigo spot runs ``bg-glow-a`` and the three spot timelines advance,
-all four pseudo-layers keep the fixed/z-index −1/pointer-events
-none/no-occlusion contract, and there is no 360px overflow.
-
-Test → story mapping (Playwright Mapping Rule):
-
-1. ``test_grid_layer_is_static`` — computed style of ``body::before``:
-   ``animationName`` is ``"none"`` (the 0.73px/s drift is gone), no
-   ``bg-grid-drift`` entry in the document animation list, and the
-   static grid ``backgroundImage`` is still painted.
-2. ``test_glow_layer_animation_running`` — ``body::after`` runs
-   ``bg-glow-a`` (26s, ease-in-out, infinite) with a matching entry in
-   the document animation list, ``playState === "running"``.
-3. ``test_glow_timelines_advance`` — ``currentTime`` of all three spot
-   timelines sampled, ~500ms waited, all advanced — the fades are truly
-   running, not paused (headless Chromium starts the document
-   animation timeline ~1s after load, so the first sample polls until
-   the timelines are alive).
-4. ``test_background_layers_contracts`` — all four pseudo-elements
-   (body ``::before``/``::after`` + the phase-25 ``html
-   ::before``/``::after`` spots): ``position: fixed``, ``z-index: -1``,
-   ``pointer-events: none``, ``inset: 0`` (UI Structure Check: behind
-   content, click-through, full-viewport); the page canvas stays on
-   ``<html>`` (``rgb(15, 10, 10)`` = ``var(--bg)``) and ``<body>``
-   stays transparent (``rgba(0, 0, 0, 0)``) — the no-occlusion
-   contract.
-5. ``test_no_horizontal_overflow_with_layers`` — at a 360px viewport
-   ``documentElement.scrollWidth <= clientWidth`` (the phase-07 pin,
-   replicated locally — the ``fixed; inset: 0`` layers must add no
-   width).
-
-Chromium note: pseudo-element CSS animations are enumerated by
-``document.getAnimations()``, NOT by ``document.body.getAnimations()``
-(verified on Chromium 151 — the element-level list is empty for
-pseudo-layers), so tests 1–3 match on ``animationName`` in the
-document-level list. The two ``html`` pseudo-layers' computed styles
-come from ``getComputedStyle(document.documentElement,
-"::before"/"::after")``.

+"""Phase 78 E2E (Playwright): the background is fully static.
 
-Story: ``.agents/user_stories/background-no-motion.md`` (supersedes
-``background-animation.md``)
+Source: ``TODO.md`` L4 — owner direction: "Remove the animated css
+background, it's too resource intensive" (supersedes the phase-25
+fading-glow contract of the ``background-no-motion`` story; the
+superseded chain is 08 → 25 → 78).
 Run in isolation (DB must be up: ``podman compose up -d db``):
 
     uv run pytest tests/e2e/test_background_no_motion.py -v --no-cov
 
-Owner report (2026-08-25, chat): the phase-22 background "jitters down
-and to the right every second and it slowly blinks brighter and darker.
-It should be smooth, fluxuating, dimming and brightening, but not
-moving. Different bright spots should slowly fade in and out."
+The three opacity-fading glow spots (``body::after`` / ``html::before``
+/ ``html::after``), their glow keyframes, and the
+``prefers-reduced-motion`` rule that stilled them are deleted from
+``styles.css`` — the infinite CSS animations ran continuously on every
+page, in every tab. The 44px grid texture (``body::before``) STAYS: it
+is static (zero animation cost). All other UI animations (typing dots,
+spinner, toasts, nav slide, …) are untouched.
 
-The two root causes (phase-22 measurements in
-``.agents/reports/22_background_animation/``):
-  - the "jitter" was the grid's 44px/60s drift (0.73px/s, diagonally
-    down-right) — a 1px line translated sub-pixel by sub-pixel
-    rasterizes with per-frame stepping, not smooth motion;
-  - the "blink" was the whole-layer 14s opacity 0.85↔1 + scale(1)↔
-    scale(1.05) pulse — one synchronized pulse reads as blinking.
-
-The fix (styles.css, pure CSS, zero JS — A11): the grid (``body::before``)
-is a STATIC texture (no animation, ``bg-grid-drift`` deleted), and three
-independent soft glow spots each run their own SLOW opacity-only fade —
-``body::after`` (phase-08 indigo) runs ``bg-glow-a`` 26s,
-``html::before`` (phase-08 cyan) runs ``bg-glow-b`` 34s with −12s delay,
-``html::after`` (a third indigo) runs ``bg-glow-c`` 42s with −23s delay.
-The out-of-phase 26/34/42s cycles (LCM 4641s) make the total light
-fluxuate smoothly and irregularly — no blink, no jitter, no movement.
-
-This suite proves the *behavior* the unit source pins only describe, in
-a real Chromium viewport: the grid is static, the three spots run
-distinct opacity-only fades whose timelines advance and whose light
-measurably changes, no ``bg-*`` keyframe animates anything but
-``opacity`` (the deterministic no-movement proof), all four layers keep
-the fixed/z-index −1/pointer-events-none/no-occlusion contract,
-reduced motion stills all four, and there is no 360px overflow.
+This suite proves the *behavior* the unit source pins
+(``tests/unit/test_background_no_motion.py``) only describe, in a real
+Chromium viewport: the three glow pseudo-elements report no
+background-image, ``animation-name: none``, and no box at all (the
+rules are gone), no ``bg-*`` keyframes or running ``bg-*`` animations
+exist anywhere, the grid is still painted and static, the
+no-occlusion canvas contract survives (``<html>`` owns ``var(--bg)``),
+reduced motion changes nothing (already static), and there is no
+360px overflow.
 
 Test → story mapping (Playwright Mapping Rule):
 
-1. ``test_grid_layer_is_static`` — computed ``animationName`` of

-   present (the static texture survives).
-2. ``test_three_glow_layers_run_distinct_fades`` — ``body::after`` →

-   (34s), ``documentElement::after`` → ``bg-glow-c`` (42s); each
-   ``ease-in-out`` + ``infinite`` with a matching
-   ``playState === "running"`` entry in the document animation list;
-   the three durations are pairwise distinct.
-3. ``test_no_motion_properties_in_background_keyframes`` — walks
-   ``document.styleSheets``; across every frame of every ``bg-*``
-   ``KEYFRAMES_RULE`` the set of declared property names is exactly
-   ``{"opacity"}`` — no ``transform``/``background-position`` anywhere
-   (the deterministic no-movement proof).
-4. ``test_glow_timelines_advance`` — poll until all three timelines
-   report ``currentTime > 0`` (headless Chromium starts the document
-   timeline ~1s after load), sample, wait ~500ms, each advanced
-   ≥ 200ms.
-5. ``test_background_light_actually_changes`` — (a) the computed
-   ``opacity`` of ``body::after`` changes by ≥ 0.05 within ~8s (a real
-   fade, not a frozen frame); (b) two clipped screenshots ~4s apart of
-   the bottom-left glow region (the ``html::after`` spot at 14%/86%)
-   differ in bytes — the light visibly changes while nothing moves
-   (a fresh ``/`` page has no other animation, so the diff is the
-   background's).
-6. ``test_background_layers_contracts`` — all four pseudo-layers:
-   ``position: fixed``, ``z-index: -1``, ``pointer-events: none``,
-   top/right/bottom/left all ``0px``; the ``documentElement`` computed
-   background is ``rgb(15, 10, 10)`` (``var(--bg)`` — the canvas stays
-   on ``html``); ``document.body`` computed background is
-   ``rgba(0, 0, 0, 0)`` (no occlusion).
-7. ``test_reduced_motion_stills_all_layers`` —
-   ``reduced_motion="reduce"`` context: all four pseudo-layers report
-   computed ``animationName`` ``"none"`` and still carry a
-   ``backgroundImage`` (the static background remains visible).
-8. ``test_no_horizontal_overflow_with_layers`` — 360px viewport:
-   ``documentElement.scrollWidth <= clientWidth`` (the phase-07 pin).
-
-Chromium notes (verified on Chromium 151, kept from the phase-22 suite):
-pseudo-element CSS animations are enumerated by
-``document.getAnimations()``, NOT by
-``document.body.getAnimations()`` (the element-level list is empty for
-pseudo-layers), so the running/advancing checks match on
-``animationName`` in the document-level list. And the computed styles
-of the two new ``html`` pseudo-layers come from
-``getComputedStyle(document.documentElement, "::before")`` /
-``("::after")`` — ``document.body`` only carries the two
-``body`` pseudo-layers.
+1. ``test_background_layers_computed_styles`` — computed styles:
+   ``body::before`` keeps the grid (``backgroundImage`` non-empty,
+   ``animationName: none``); ``body::after`` / ``html::before`` /
+   ``html::after`` report ``backgroundImage: none`` +
+   ``animationName: none`` + ``position: static`` + ``content: none``
+   (the pseudo-elements have no box — the rules are deleted, not just
+   stilled); the page canvas stays on ``<html>`` (``rgb(15, 10, 10)`` =
+   ``var(--bg)``) and ``<body>`` stays transparent (no occlusion).
+2. ``test_no_background_keyframes_or_animations`` — deterministic
+   static proof: no ``@keyframes`` rule with a ``bg-`` name in any
+   live stylesheet, and no running ``bg-*`` entry in
+   ``document.getAnimations()`` (pseudo-element CSS animations are
+   enumerated by the document-level list, not the element-level one —
+   verified on Chromium 151).
+3. ``test_grid_layer_is_fixed_behind_content`` — the surviving grid
+   layer keeps the UI-structure contract: ``position: fixed``,
+   ``z-index: -1``, ``pointer-events: none``, ``inset: 0`` (behind
+   content, click-through, full-viewport).
+4. ``test_reduced_motion_background_static`` — a
+   ``reduced_motion="reduce"`` context: the grid is still painted and
+   static, the deleted glow layers still report no image/animation —
+   nothing is resurrected under reduced motion.
+5. ``test_no_horizontal_overflow_with_layers`` — 360px viewport:
+   ``documentElement.scrollWidth <= clientWidth`` (the phase-07 pin —
+   the background adds no width).

+"""Phase 77 E2E (Playwright): navbar re-shows refresh the view's data —
+the story suite for the phase-77 refresh hook + the History refresh
+button.
+
+Source: TODO.md L3 — "Clicking navbar icons should refresh the relevant
+page. For example, clicking 'history' doesn't load new history until I
+refresh. The history page should also have a refresh button."
+
+Since the phase-76 shell, a view's data was fetched exactly once, at
+mount (mount-once, hide-forever) — a History view opened at 10:00 still
+showed 10:00's data at 10:30. Phase 77 makes every USER-INITIATED
+re-show of an already-mounted view re-fetch its list: the router
+dispatches ``bor:view-refresh`` on the view's section (a switch back
+onto it, a re-click of its own nav link — NO pushState — or back/
+forward onto it; the first show and boot never), the four data views
+(History, RAG, Sources, Tuning) listen and re-run their loads, and the
+History view gains an explicit Refresh button in its page-head (the
+owner's second half of L3). The Chat view is deliberately excluded
+(the in-flight stream and local conversation persist — the phase-76
+contract; the unchanged ``test_nav_switch_keeps_stream.py`` suite is
+the additional control).
+
+Run in isolation (DB must be up: ``podman compose up -d db``):
+
+    uv run pytest tests/e2e/test_navbar_refresh.py -v --no-cov
+
+The "freshness" proof (the house pattern from the phase overview):
+create new backing data via the API AFTER a view has loaded, nav back
+(or re-click / press Refresh), assert the new row — with the phase-76
+canonical same-document sentinel (a ``window`` global set before the
+nav clicks is still readable after — no document load).
+
+Test → story mapping (Playwright Mapping Rule):
+1. ``test_reshow_refetches_history`` — THE L3 REPRO: saved chat A
+   visible on History; chat B created via the API while Chat is up;
+   Chat → History: row B appears (replaced list — no duplicates), the
+   window sentinel survives every click (same document).
+2. ``test_active_view_reclick_refetches`` — a re-click of the ACTIVE
+   view's own nav link re-fetches (today a no-op): chat C created via
+   the API while History is up; click History AGAIN → C appears, the
+   URL is still /history.html and ``history.length`` is unchanged (no
+   pushState).
+3. ``test_history_refresh_button`` — the explicit Refresh control
+   (TODO.md L3's second half): chat D created via the API; click
+   #history-refresh → D appears, #history-status announces "Saved
+   chats refreshed.", the button is disabled while the request is in
+   flight (the house hold-the-request pattern — deterministic, not a
+   race) and re-enabled after (accessible name + keyboard focus
+   pinned too).
+4. ``test_popstate_refetches_history`` — back/forward onto an
+   already-mounted view re-fetches: Chat → History (loads) → Chat →
+   create E via the API → ``page.go_back()`` (popstate) → History →
+   E present.
+5. ``test_all_four_data_views_refetch_on_reshow`` — one assertion per
+   data view (History, RAG, Sources, Tuning): the GET to the view's
+   list endpoint is exactly +1 on a re-show (the request-log pattern
+   from task 02) — the first show (the mount) is the baseline.
+6. ``test_stream_surval_control`` — the phase-76 CONTRACT control with
+   the hook in place: send a question (the mock LLM's ~8 s stream) →
+   mid-stream nav to RAG → back to Chat → the FULL answer completes
+   and the turn settles (one query_log row). The unchanged
+   ``test_nav_switch_keeps_stream.py`` run in isolation is the
+   additional control.

-"""Phase 05 E2E (Playwright): onboarding suggestion chips, one-tap submit.
+"""Phase 80 E2E (Playwright): onboarding chips = the last 3 questions asked.
+
+Story: ``.agents/user_stories/suggestion-chips.md`` (phase 05) —
+REWRITTEN in place for the phase-80 semantics (the phase-76 precedent:
+a semantic change rewrites the story suite in place). Source:
+``TODO.md`` L6.
+
+The new contract (owner decision A6): the empty-state chip row is the
+3 most recent user questions across ALL saved chats — chats walked
+newest-``updated_at`` first, each chat's messages newest-first,
+exact (case-sensitive) de-duplicated, cap 3. A fresh deployment — zero
+saved questions — gets the SEED list instead (``BOR_SUGGESTIONS`` /
+the built-in default). 1–2 saved questions → exactly those chips (NO
+mixing with the seed). The row refetches when the empty state comes
+back (New chat), so it is never stale. The deflection "Maybe try"
+chips are a separate contract (``derive_suggestions``) — untouched.
+
+The four states pinned here:
+
+* **seed** — fresh DB (no saved chats) → the chip texts equal the
+  built-in default list EXACTLY (the ``SEED`` literal below is the
+  pin for the exact seed list — ``tests/unit/test_config.py`` pins
+  only the shape) — rendered as accessible buttons in the role=list
+  group, exactly as the phase-05 component contract;
+* **last-3** — two saved chats with 5 user questions total (the older
+  one saved FIRST — the API stamps ``updated_at``) → a fresh page
+  load shows EXACTLY the 3 newest questions, newest-first;
+* **partial** — exactly 2 saved questions deployment-wide → exactly
+  2 chips (no seed top-up — the A6 contract, visible in the UI);
+* **refetch** — boot with the seed chips, save a chat whose newest
+  question is Q via the API, click New chat (``#new-chat-btn``) → the
+  chips now are Q, and the request log shows a SECOND
+  ``GET /api/suggestions`` (the boot fetch was the first).
+
+Carried-over story behavior (unchanged semantics from the phase-05
+suite): one-tap submit (chip click → composer filled → submitted →
+the mock-LLM brain bubble), Tab+Enter keyboard reachability of the
+chips (the keyboard-walk assertion), and the mobile single
+horizontal-scroll row.
+
+The endpoint is authed (phase 79, ``require_user``), so every test
+signs in as admin first (``auth_helpers.login``). ``saved_chats`` is
+global state on the shared e2e Postgres AND the state this contract
+reads — the autouse fixture truncates it before and after EVERY test
+(including the ones whose turns auto-save a row), so each test starts
+from — and leaves — an empty deployment.

-
-The onboarding row in the empty state renders real ``<button>`` chips from
-``GET /api/suggestions`` (settings defaults). Clicking — or Tab + Enter —
-fills the composer AND submits: one tap produces a user bubble with the
-chip's exact text and a streamed Brain reply. On mobile (375px) the row
