Build and Push Containers / build-and-push-app (push) Successful in 8s
phase: 02_sharp_capture
**Phase 02 final verification pass — complete, 100% green.**

**Verified (all 4 tasks in `complete/02_sharp_capture/`):**
- Task 1: `pickSurface()` requests `screen × devicePixelRatio` (capped 3840×2160) instead of window size
- Task 2: `degradationPreference: "maintain-resolution"` + per-leg `maxBitrate`, re-applied after `setLocalDescription` *and* on `connected` (both call sites asserted in `test_app.py`)
- Task 3: default cap raised to 25 Mbit/s — `config.py` constant, `net.js` offline fallback, `.env.example`, README, and the drift-guard test all agree
- Task 4: realdisplay sharpness floor (viewer decoded width ≥ 1152px = 90% of Xvfb 1280px) in `test_sharp_picture_reaches_the_wall`

**Gates (all green):**
- `uv run ruff check . && uv run ruff format --check .` → clean
- `uv run pyright` → 0 errors
- `uv run pytest` → 231 passed, 3 skipped (realdisplay), coverage 95%
- `MIRROR_REALDISPLAY=1 uv run pytest -m realdisplay` → 3 passed on a real Xvfb + headed Chromium

**Completion criteria:** (1) 90% width floor asserted on viewer's decoded pixels — PASS · (2) `/api/config` `maxBitrateBps: 25000000` default, net.js fallback agrees — PASS · (3) `#stat-resolution` matches viewer-decoded size incl. documented window downscale (1100×620, 1280×720 fake-device tests) — PASS · (4) both suites green, aspect-ratio guard (`1280/800` ± 0.06 + `≠ 1280×720`) still distinguishes real from fake capture — PASS · (5) README Configuration documents `25000000` — PASS; `PLAN.md` §6 "default 12 Mbit/s" left untouched as instructed — **flag for the user to amend**.

**Docs:** README — fixed suite timing `~20s → ~50s` (measured 49s); all other claims verified (CLI flags, dev extra, config table, kiosk key table vs. `watch.js`/`share.js` routers, kiosk commands vs. `docs/kiosk-silverblue.md`). AGENTS.md — same stale timing fixed, nothing else stale (all referenced test names/files exist).

**Notable:** `docs/kiosk-silverblue.md` + its scripts use `mirror.reeselink.com` while README/SECURITY.md/Containerfile use `mirror.reeseapps.com` — a pre-existing cross-file mismatch I could not resolve from the repo (both in same-day commits; live-infra fact). Left untouched; user should confirm the live kiosk URL. No live changes made.

**Next pending phase:** `03_audio_share`.
