**Phase 21 final verification pass** (all 3 task files already in `complete/`, working tree carries the implementation)
- **Verified** task 01: `#pause`/`Space`/`setPaused`/`_paused` gone — `grep -ri pause src/dashboards/web/` empty, 0 pause hits in all 8 served pages + 10 static assets; re-ran `data/logs/21-task01-nopause.cjs` → 30/30 PASS (hidden tab: 0 data fetches in 22 s, one poll 2 ms after return).
- **Verified** task 02: re-ran `21-task02-gpu-values.cjs` on the live fleet → all PASS (deskwork/driveripper show Model/VRAM/Pool/Temp at 16.3 px; gateway = 5 heroes, slot `hidden`, no `n/a`; hero order unchanged; GPU history chart still builds per host).
- **Verified** task 03: re-ran `21-task03-scroll.cjs` → 14/14 PASS (`class="data scroll"`, scrollWidth 1021 vs clientWidth 292 at 360 px, Rotate/Revoke/bundle reachable and hit-testable; unchanged at 1280 px). Screenshots refreshed in `data/logs/`.
- **Gate**: `uv run pytest` → **1471 passed, 15 skipped**; `--cov --cov-fail-under=94` → **98.94%**; `ruff check src tests agent` clean; `pyright` **0 errors**; `bash .agents/validate.sh` → **EXIT 0** (incl. `node --check`); `uv run pytest -m live --live` → **11 passed**; `/api/health` all 9 sources `ok`.
- **Docs fixed** (pre-existing + this phase): "all **eight** signed-in pages" was a miscount of `MARKUP_PAGES` (7 = 5 dashboards + `/settings` + `/certs`; `/login` is the 8th, unsigned) → corrected in `README.md`, `AGENTS.md` (×2) and the `tests/test_api.py` docstring/comment; `AGENTS.md` Commands hermetic tally 1470 → **1471**.
- **Docs reviewed, consistent**: Quickstart/commands/flags (`install-agent.sh`, `capture-fixtures.sh`, `dev-server.sh`), the env table vs `config.py`, every documented route vs the served route table, masthead/`/system` GPU/`/certs` scroll descriptions vs code, and all `data/logs/*` + `tests/fixtures/*` references.
- **Deviation**: `validate.sh`'s advisory `fastapi 0.153.0 → 0.156.4` left alone — no dependency was touched this phase, so AGENTS rule 8 ("check after touching dependencies") is not triggered; upgrading here would be an unrelated behaviour change.
- No live-infra changes made (repo-side + browser verification only).
- **Next pending phase**: `22_disks_hide_unconfigured`.
