Surfaces realism subsystem state on the existing worker heartbeat
extra hook (system.orchestrator.health) — no new bus topic. Payload
carries {llm_enabled, llm_backend, llm_model, llm_breaker_state}, so
the dashboard's worker panel renders a live LLM badge with a colored
breaker-state dot:
closed (green) — LLM healthy
half_open (amber) — cooldown elapsed; next call is a probe
open (red) — short-circuiting to deterministic templates
Heartbeat is the canonical worker self-report channel; piggybacking on
extra(...) avoids a new topic family while keeping the snapshot
recomputed each beat (30s).
Route all lucide-react icon usage through a single src/icons.ts
re-export that imports each icon from its own per-icon module
(lucide-react/dist/esm/icons/<name>) instead of the barrel.
Bundle-size impact: none (29kB icons chunk unchanged — tree-shaking
was already effective with sideEffects:false). Dev-experience win:
Vite transforms 247 modules instead of 1848 because the dep
optimiser no longer pre-bundles the full lucide barrel — faster
cold start and HMR.
Ambient d.ts declares the wildcard module so TS accepts per-icon
imports; lucide ships .d.ts only for the barrel.
Seven icons were renamed upstream and still work through the barrel
via aliases (AlertTriangle -> triangle-alert, BarChart3 -> chart-column,
CheckCircle -> circle-check-big, Filter -> funnel, PlusCircle ->
circle-plus, Sliders -> sliders-vertical, UploadCloud -> cloud-upload,
Fingerprint -> fingerprint-pattern). Component call sites stay on
the legacy names; the renames live only in icons.ts.
Per-row START button enabled iff `installed && status !== 'ok'`;
tooltip explains why it's disabled ("Unit not installed" /
"Already running"). Transient `starting` state shows `...` on the
button and auto-clears after 15s so the UI never gets stuck if the
heartbeat is slow.
START ALL WORKERS button in the header calls /workers/start-all and
renders the three counts in the toast:
`STARTED · N · ALREADY RUNNING · M · FAILED · K (first failure: …)`.
Tone flips to alert when K > 0.
