## Summary
Implements the React Effects Policy by creating the approved hook
surface in `hooks/effects.ts` and migrating a broad set of direct
`useEffect` calls across the codebase to either purpose-named hooks or
non-effect patterns.
### Plan Summary
- Add `hooks/effects.ts` exporting `useMountEffect`, `useInterval`,
`useTimeout`, `useDebouncedValue`, `useWindowEvent`, `useDocumentEvent`,
`useDocumentTitle`, `useMediaQuery`, `useLocationHash`, and
`useResizeObserver`
- Extract large imperative effects into purpose-named hooks:
`useTerminalSession`, `useFloatingTooltipMeasurements`,
`useAnnotatedRunGraphSvg`, `useInstallEffects`, and others
- Move install session fetch from a component effect into a SWR query
(`install-query.ts`)
- Replace `useEffect` + `useState` state-derivation patterns with
render-time computation or ref callbacks
- Replace `AskFabroLayoutProvider`/`useAskFabroLayout` context with a
prop callback
## What changed and why
**`hooks/effects.ts`** — the new approved primitive surface. All
internal `useEffect` calls here are intentional; the hooks expose the
*external system* they manage rather than leaking `useEffect` to
component code. `useMediaQuery` and `useLocationHash` use
`useSyncExternalStore` instead of effect + state.
**`useTerminalSession`** — the largest extraction. The 130-line
xterm/WebSocket/ResizeObserver setup block moves from
`terminal-view.tsx` into its own hook, which now owns the `terminalRef`,
`fitRef`, and `socketRef` that previously cluttered the component.
`TerminalConnectionError` and `ConnectionStatus` types are exported from
the hook.
**`useFloatingTooltipMeasurements`** — extracts the `useLayoutEffect` +
ResizeObserver + window resize listener out of `FloatingTooltip`. The
`FloatingTooltipSize` type moves with it so consumers don't need to
import from the component.
**`useInstallSessionQuery` + `useInstallEffects`** — the install session
fetch moves from a component effect to SWR (`install-query.ts`). The
three remaining install effects (token URL scrubbing, GitHub error URL
scrubbing, health-poll restart) move into
`hooks/use-install-effects.ts`. The root-redirect effect is replaced
with a render-time `<Navigate>` gate. The `SessionState` discriminant
now carries `token` so stale query results can be discarded without an
effect chain.
**`SelectionCheckbox`** — `useEffect` setting `input.indeterminate` is
replaced with a ref callback, which runs synchronously after the node is
attached and avoids a stale-frame flash.
**`event-debug.tsx`** — the manual `window.addEventListener("keydown",
...)` pattern is replaced with `useWindowEvent`, removing the
`react-doctor-disable` suppression comments.
**`run-waterfall.tsx`** — the local `useTickingNow` is deleted;
`RunWaterfall` now calls the shared `useTickingNow` from `lib/time` with
the new `active` parameter signature.
**`toast.test.tsx`** — `useEffect(() => onReady?.(api), ...)` in the
test helper is replaced with a direct call during render, which is valid
because `onReady` has no side effects that React cares about.
**`AskFabroSidebar`** — `setIsResizing` from the layout context is
replaced with an `onResizeActiveChange` prop, removing the
`useAskFabroLayout` call and the hidden context coupling from the
sidebar.

## Summary
Improves the web UI's React Doctor audit score by separating reusable
helpers from React component modules, tightening effect/state ownership,
and extracting real component boundaries in the install wizard, stage
activity view, run-files diff browser, RunDetail route, and Runs
workspace. The branch removes the previously deferred RunDetail and Runs
giant-component diagnostics without changing RunDetail UX, route
contracts, action ordering, or Runs workspace behavior.
| Metric | Main baseline | Initial PR | Current PR |
|--------|---------------|------------|------------|
| React Doctor score | 63 | 71 | 99 |
| React Doctor errors | 123 | 0 | 0 |
| React Doctor warnings | 241 | 163 | 3 |
| React Doctor diagnostics | 364 | 163 | 3 |
## Changes
- Moves exported helper logic out of component files so Fast
Refresh/component-export rules no longer dominate the audit.
- Adds a targeted React Doctor config exception for React Router route
modules, where non-component exports like route metadata are
intentional.
- Refactors low-risk state/effect patterns: keyed interview question
state, reducer-backed editable run title state, event-owned preview
opening, route-keyed insights editor initialization, refresh timer
ownership, and selection/derived list cleanup.
- Reworks `InstallApp` around an install reducer, a controller hook for
install lifecycle state, and focused wizard step components for LLM,
server, object-store, sandbox, and GitHub setup.
- Moves `RunStages` selected-stage activity into a keyed boundary for
panel/debug detail state while preserving stage activity filters across
navigation.
- Extracts the `RunFiles` loaded diff-browser view from route/query
coordination so the route owns data/URL state and the loaded view owns
rendering.
- Splits `RunDetail` into route-local header, actions, tab shell, docked
controls, model, and lifecycle-toast modules; the actions menu now uses
grouped descriptors instead of a large boolean/callback prop matrix.
- Extracts Runs workspace preference ownership into
`useRunsWorkspacePreferences` and moves toolbar rendering into
`RunsToolbar`, leaving the route focused on data, DnD state, filtering,
and view selection.
- Guards `InsightsEditor` query execution with a latest-run id and
timeout cleanup so stale or unmounted mock query runs cannot overwrite
newer results.
- Adds regression coverage for archived-run deletion from RunDetail and
stale-result handling in InsightsEditor.
- Improves semantic/accessibility coverage with labeled controls, native
meter/section semantics, decorative status dots, and clearer unavailable
copy.
- Removes dead UI code and applies local suppressions only where the
rule is a documented false positive or an intentional imperative
integration boundary.
## Remaining React Doctor warnings
Current score is 99 with 0 errors and 3 warnings. The remaining warnings
are intentionally left for separate judgment rather than mechanical
churn:
- `prefer-useReducer` (3): `AutomationsNew`, `InsightsEditor`, and
`CreateSecretForm` need reducers only if they encode real coupled
transitions, not simple field setters.
## Verification
- `cd apps/fabro-web && bun test app/routes/run-detail.test.ts` -> `22
pass`, `0 fail`
- `cd apps/fabro-web && bun test app/routes/insights-editor.test.tsx
app/routes/runs.preferences.test.tsx` -> `7 pass`, `0 fail`
- `cd apps/fabro-web && bun run typecheck`
- `cd apps/fabro-web && bun test --isolate` -> `490 pass`, `0 fail`
- `cd apps/fabro-web && bunx react-doctor@latest --full --json >
/tmp/fabro-react-doctor-runs-insights.json` -> score `99`, `0` errors,
`3` warnings
- Earlier branch verification also included `cd apps/fabro-web && bun
run build`
- `git diff --check`

The left sidebar tracked when it first *observed* a running stage
(Date.now() on mount) instead of the stage's actual startedAt, so the
duration reset to 0s on every page load.
Compute elapsed time directly from stage.startedAt via a shared
elapsedSecsSince helper, dropping the runningStartRef tracking. The
stage meta bar already did this correctly but with a duplicated parser;
fold it onto the same helper.

### Summary
Billing and stage lists now use the event-sourced `RunProjection` as
their source of truth, so running and retrying stages appear immediately
and runtimes keep advancing in the UI. This removes the checkpoint
completed-node bypass that hid in-flight work and froze totals until the
next server response.
### Plan Summary
- Store stage `started_at`, terminal `duration_ms`, server-internal
`usage`, and lifecycle `state` on `StageProjection`.
- Populate those fields from stage lifecycle events, including retry
transitions and per-attempt reset on new starts.
- Render `/runs/{id}/stages` and `/runs/{id}/billing` from
`RunProjection.iter_stages()`.
- Expose the new API/client fields and tick in-flight billing runtimes
on the web UI.

Events["Stage lifecycle events"] --> Projection["RunProjection StageProjection"]
Projection --> StagesAPI["GET /runs/{id}/stages"]
Projection --> BillingAPI["GET /runs/{id}/billing"]
StagesAPI --> StageUI["Stage sidebar/stages view"]
BillingAPI --> BillingUI["Billing tab live totals"]
```
### Key decisions
Retry and revisit handling stays one row per node id: latest visit data
wins, while first-seen event sequence keeps ordering stable with
finalize output. `state` is stored rather than derived so `Retrying` is
representable, and old serialized projections still work through the
`effective_state()` fallback. Billing `usage` remains server-internal
and is skipped on the wire; public schemas only expose the fields needed
by `/stages`, `/billing`, and the frontend live timer.
Added focused reducer, server retry/revisit, API round-trip, billing UI,
and event invalidation coverage.

These endpoints had zero CLI callers and served only the web UI demo.
Verification and retros were `not_implemented` stubs in real mode;
sessions had an in-memory implementation but no CLI usage. Removing
them shrinks the API surface and eliminates ~9,000 lines of dead code.
