phase: 07_llm_monitor_style_pages

**Phase 07 final verification pass — all tasks already in `complete/`; every criterion re-verified live.**

- **Old slot table gone**: no `#slots-card`/`#slots-table`/`renderSlots` in HTML/JS/CSS (only the new grid's `.slots-empty` *class*); pinned by `test_the_broken_slot_table_is_gone_from_html_js_and_css`.
- **`tests/fixtures/slots_gufo.json`**: present; live `GET ${GUFO_BASE_URL}/slots` this pass matches it key-for-key (row + `next_token[0]`), so the capture is reproducible; drift proven to fail (mutation tests + live `test_gufo_slots_answer_the_pinned_shape`, 9 live tests pass).
- **Aggregate block**: live page shows `2 of 2 engines`, running/waiting/prompt/decode/total-tokens straight from `fleet_totals()`, dot `ok`, no verdict colour; on a throwaway single-engine instance (:8091, private temp DB) `#fleet` is `hidden`, one full-width strip card + one panel, zero banners → "one clean half".
- **Strip + slot grid on live data**: 2 `.card.stat` (KV bars `bar ok` 13 %/0 %), gufo grid rendered real cards incl. a busy slot (`#2189`, 67849 prompt tok, 99 % cache share, `processing`), vLLM note-only with no grid; no `NaN`/`undefined` anywhere. Screenshots: `data/logs/llm-phase07-final-live-{two-engines,single-engine}.png`, `ups-charts-aria-labels.png`.
- **Defect found in earlier work and fixed**: `/ups`' four `LineChart`s shipped no `ariaLabel`, violating AGENTS.md's "every chart names itself for assistive tech" (`/system`+`/llm` were pinned, `/ups` wasn't) → added labels to `page-ups.js` and `test_every_ups_chart_names_itself_for_assistive_tech`; browser-verified `role="img"` + label on all four.
- **Gate**: `bash .agents/validate.sh` → **exit 0**; `uv run pytest --cov --cov-fail-under=94` → **604 passed, 9 skipped, coverage 97.91 %**; `uv run ruff check src tests agent` → All checks passed; `uv run pyright` → **0 errors**; `node --check` every page script ok; `uv run pytest -m live --live` → **9 passed**; `uv pip list --outdated` empty.
- **Docs**: README + AGENTS.md reviewed end-to-end; fixed test count (582→604), `/llm` source column + both architecture diagrams now name gufo `/slots`, AGENTS.md agent line gained `GET /schema` + status page, ariaLabel convention now covers all three chart pages, README Testing block now lists `bash .agents/validate.sh`. Env-var table, agent/install flags, Containerfile facts, `/api/*` shapes, range chips, remote URL all verified accurate — no other changes needed.
- **Live-infra**: no fleet/host/config change; the temp :8091 instance, its temp DB and the fake processes are removed; dev server restarted and `/api/health` `ok` (all 6 sources ok). One thing I deliberately did **not** touch: the gitignored local `.env.dev` still carries a comment claiming the NUT `[dashboards]` account has only battery-test `instcmds`, whereas AGENTS.md/README record `instcmds = all` (verified on hardware 2026-10-17) — operator-owned file, flag for the operator to reword.
- **Next pending phase**: `08_events_paging_and_copy`.
