From 736da1c1efb8f44f64b00e0046efd25d6249e974 Mon Sep 17 00:00:00 2001 From: ducoterra Date: Tue, 3 Nov 2026 09:53:38 -0500 Subject: [PATCH] phase: 07_kiosk_layout_state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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`. --- .../07_kiosk_layout_state/00_phase.md | 0 .../01_arrange_and_layout_frames.md | 0 .../02_registry_layout_policy.md | 0
