feat(kiosk): self-recover a hung wall and page when it goes quiet
An unattended wall failed in two ways on 2026-11-02. It hard-hung with the kernel alive but userspace unable to start a process: ssh completed the handshake and closed 6-13 ms later with zero bytes and no banner, while 62 GiB RAM and zero OOM lines rule out memory. Separately, the service knew at 14:03Z that nothing was watching (healthz viewers:0) and nothing was reading it. It was discovered by walking over to the panel. Hang recovery, two independent layers (install step 7/9, asserted by check-kiosk.sh): - /etc/sysctl.d/90-mirror-wall-selfheal.conf: soft lockup, hard lockup and any oops escalate to a panic, and kernel.panic=30 reboots instead of parking. - /etc/systemd/system.conf.d/90-mirror-wall-watchdog.conf: PID 1 must keep kicking the iTCO hardware watchdog or the chipset resets the box, which is the layer that covers a kernel too wedged to notice. Clamped to the driver's own 30s because systemd kicks at a third of whatever value it is handed. Presence alerting: docs/wall-watch/ runs on the server host, probes loopback /healthz (exempt from the address gate) every minute, debounces three checks, pages over ntfy and then announces the recovery. WALL_DRILL=1 labels a test page in the title, body and priority so a drill can never be mistaken for an incident. Verified against a fake ntfy: caller environment wins over the config file, both transitions fire, and the debounce holds. Firewall (install step 8/9): drop FedoraWorkstation's 1025-65535/tcp. The UDP half is load-bearing for peer-to-peer media (mirror deliberately uses no STUN/TURN) and stays open; the TCP half was every high port on a box whose only access control is its address. Measured, not assumed: a live share kept flowing at 459.6 kbit/s inbound with the TCP range closed, and tcp/8080 stopped answering from a same-subnet host. Also fixed: install-kiosk.sh overwrote an existing client's kiosk.conf with its built-in default URL, so re-running it to repair a wall silently repointed it at the production default. An existing URL now wins and KIOSK_URL= is an explicit change. Documented with the evidence: why gnome-remote-desktop cannot share a gnome-kiosk session (gnome-kiosk exports no org.gnome.Mutter.* names, so grd has nothing to capture, and this image has grdctl rather than grdc), and why no userspace RDP would have survived the hang either.

phase: 04_reachable_share_cta
All verification is complete. The pending working-tree changes are exactly the phase 04 work (CSS, tests, the README narrow-screen line, the AGENTS.md "Two→Three pages" fix) — all accurate. ## Final report **Verified (final pass — all 4 task files present in `complete/`):** - Gate 1: `uv run ruff check . && uv run ruff format --check .` → all checks passed, 29 files formatted - Gate 2: `uv run pyright` → 0 errors - Gate 3: `uv run pytest` → **269 passed, 4 skipped** (realdisplay-gated), coverage 95% - Gate 4: `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → **3 passed, 1 skipped** (host delivers no audio source — documented in module docstring) **Completion criteria:** 1. `#start` elementFromPoint at the 11 required sizes — ✅ `TestIdleShareButtonReachable` sweeps 12 viewports (superset); 12/12 passed 2. `#stop` clickable while sharing — ✅ `TestLiveStopButtonReachable` (320×568, 390×844, 1280×450) passed, incl. placeholder-hidden + livetag assertions 3. Single-cell stage guard — ✅ `test_the_share_stage_is_one_cell` + `test_the_stage_has_a_floor_and_a_ceiling` passed; CSS has `grid-template: 1fr / 1fr`, `.stage > * { grid-area: 1 / 1 }`, `min-height: 264px`, `max-height: min(70svh, 640px)` + vh fallback, `.placeholder { max-height: 100%; overflow: auto }`, `align-content: safe center` 4. Live video fills stage, rounded corners, `#livetag` top-left — ✅ verified by live-browser probe: video fills stage (decoded), stage radius 14px, livetag top-left, placeholder hidden 5. README accurate, AGENTS.md current, suite 100% green — ✅ 6. Phases 01–03 unchanged — ✅ `test_keyboard_wall` + `test_audio_share` + `test_sender_fidelity`: 48 passed **Documentation:** README.md reviewed in full (page table, quickstart, all 12 config defaults vs `config.py`, CLI flags, secure-context/wayland/audio sections, kiosk key table vs `watch.js`/`share.js`, dev commands) — **consistent, no fixes needed**. AGENTS.md verified statement-by-statement (commands, routes, test names, browser/realdisplay flags) — **no stale statements; no changes needed** (the pending "Two→Three pages" fix is correct). **Decisions:** criterion 4 had no dedicated test, so verified directly with a throwaway probe reusing the e2e harness (script in /tmp, not committed). No live infrastructure touched. No defects found in prior work. **Next pending phase:** none — `todo/` is empty of other phases. |

phase: 03_audio_share
**Phase 03 final verification pass — complete, 100% green.** - Verified all 4 tasks done in `complete/03_audio_share/`; confirmed implementation in `watch.js` (one composed `MediaStream` per tile, staged-only `setMuted()` policy, `data-audio` state), `share.js` (precise `NotAllowedError` rethrow, 3 honest `#stat-audio` states, mid-share audio republish), conftest flags, and the new `tests/e2e/test_audio_share.py` (11 tests, all **passed** — none skipped). - **Criteria:** (1) viewer inbound audio `bytesReceived` strictly increases + composed stream 1 video/1 audio track while frames still decode — **passed**; (2) staged-only audio via keyboard `m`, mouse button, and `unstage()` re-mute — **passed**; (3) `shared`/`silent`/`not offered` + mid-share audio loss updates panel, roster and tiles — **passed**; (4) cancelled picker reports cancellation, single attempt — **passed**; (5) SECURITY.md §4 Audio, README platform notes, kiosk doc all describe shipped behaviour incl. Linux/PipeWire reality — **verified**; (6) full gate — **passed** (below). - **Gates:** `uv run ruff check . && uv run ruff format --check .` → clean; `uv run pyright` → 0 errors; `uv run pytest` → 245 passed, 4 skipped (only the `MIRROR_REALDISPLAY`-gated X11 tests); `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 3 passed, 1 skipped (real-capture audio: documented skip naming the exact host/flag reason, per task 04). - **Docs:** README.md reviewed in full against code (env table, CLI flags, routes, kiosk key table, quickstart, audio notes) — consistent, no changes needed. AGENTS.md — all commands/paths/coverage claims verified accurate, no stale statements, no changes needed. - **Defect fixed (pre-existing):** `docs/kiosk-silverblue.md` + `install-kiosk.sh`, `kiosk.conf`, `gnome-kiosk-script` used `mirror.reeselink.com` while README/SECURITY.md use `mirror.reeseapps.com` (the deployment domain, consistent with the fleet); corrected 7 occurrences in 4 files. - No live-infrastructure changes; realdisplay suite ran on private Xvfb only. - **Next pending phase:** `04_reachable_share_cta`. |

phase: 01_keyboard_kiosk_control
**Phase 01 final verification pass — complete, 100% green** - Verified all 4 tasks done (files in `complete/`); implementation review: key router in `watch.js`, share-page router, CSS focus/selection affordances, `?` overlay, pointer-free E2E suite — all sound. - Gates: `ruff check` + `ruff format --check` ✅ · `pyright` 0 errors ✅ · `uv run pytest` → 223 passed, 2 skipped (realdisplay), 1 pre-existing FastAPI deprecation warning · `MIRROR_REALDISPLAY=1 pytest -m realdisplay` → 2 passed ✅ · `pytest -m e2e` → 51 passed (incl. `test_keyboard_wall.py`, which a meta-test keeps pointer-free) · `node --check` on all static JS ✅. - Completion criteria: all 6 ✅ (j/k+Enter, f/g/n/p/1–9/m/?/Esc keyboard-only E2E; no hover-only controls via CSS guard + focus-ring E2E; `#name` text-safe; e2e/realdisplay green; key map documented in README "Kiosk client" and `docs/kiosk-silverblue.md`). - README fixed: added missing env vars `MIRROR_MAX_BITRATE`, `MIRROR_PING_INTERVAL`, `DEBUGPY_WAIT` to the config table; added the one-time `rpm-ostree` layering note before the kiosk install snippet. - AGENTS.md fixed: removed stale "roadmap is intentionally empty" parenthetical (3 phases pending); coverage ~94% → ~95%. No content added. - **Unresolved, needs your call:** README/SECURITY.md say `mirror.reeseapps.com`; `docs/kiosk-silverblue.md` (reference-client naming table with real IPs) says `mirror.reeselink.com`. I couldn't verify which is the live deployment domain, so I changed neither — say the word and I'll unify. - Next pending phase: `02_sharp_capture`. |

fix(kiosk): stop GDM covering the wall with a greeter after auto-login
Auto-login succeeded and the wall kept streaming, but about ten seconds after the kiosk session came up GDM autospawned a greeter on the same GPU and a login screen covered it. gnome-kiosk ships X-GDM-SessionRegisters=false, so nothing ever registers and GDM concludes the display is still free — which is why every remote check (loginctl, the mirror roster) stayed green while the physical screen showed a password prompt. Override that session file with the flag set to true, keeping the file name and session id identical: inventing an id makes GDM quietly fall back to the plain GNOME session, top bar and all. Add a per-minute guard that reclaims the foreground VT, because this class of failure is invisible from the outside, and have the checker assert both the foreground VT and the greeter-session count. That count had a silent false green: journalctl has no --no-legend, so the check read an empty stream and passed unconditionally. Also keep a copy of the payload in /usr/local/share/mirror-kiosk. /tmp is cleared at every boot, which deletes the checker just after the one event you are most likely to want to re-run it for. Verified on the reference client: a cold boot now creates no greeter session at all, the kiosk compositor and Firefox come up undisturbed, and a console stolen with chvt is taken back within a minute.

docs: the Silverblue kiosk client, installed and checked over SSH
A wall display is now a target client: Fedora Silverblue running GNOME Kiosk, auto-logged in as kiosk, showing /watch fullscreen in Firefox. docs/kiosk-silverblue/ carries the idempotent installer, a read-only checker and a probe that measures what the browser actually renders, so a second client is a copy-paste and nothing about it needs a keyboard. The runbook records what the upstream tutorial leaves out: gsettings only commits from inside the session (gnome-kiosk sets DCONF_PROFILE, so a system dconf db is never read at all), window-config.ini wins by being found first and therefore silently loses the shipped notification rules, AccountsService caches Session= until its daemon restarts, and /watch survives a bare LAN IP while /mirror cannot. Verified on the reference client: cold boot back to a subscribed wall in under 60s, viewport == window == screen at 3840x2160, and the sharer's own peer connection to it reports connected.
