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.
