## 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
Simplifies the greenfield PR/run schema surface by collapsing alias-only
type shims and removing legacy compatibility paths that kept old wire
shapes and workflow names alive.
## Changes
- Use canonical `Run`, `PullRequestLink`, `PullRequestResponse`,
`BoardColumn`, `WorkflowSettings`, SWR `Key`, and `SteerRunRequest`
names directly across Rust and web code.
- Remove legacy PR/event deserialization compatibility for old PR
records and command output fields, with tests updated to reject stale
wire shapes.
- Drop obsolete workflow aliases for `agent_loop`, `one_shot`,
`codergen_mode`, and `stack.child_dotfile`, then update docs and tests
to the current names.
## Verification
- `git diff --check`
- `cargo +nightly-2026-04-14 fmt --check --all`
- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D
warnings`
- `cargo nextest run -p fabro-types -p fabro-api -p fabro-client -p
fabro-store -p fabro-server -p fabro-workflow -p fabro-cli`
- `cd apps/fabro-web && bun run typecheck`
- `cd apps/fabro-web && bun test`

Replaces the /settings/live-events placeholder with a working page that
streams server-wide events from /api/v1/attach. Shares the leader-owned
cross-tab EventSource so additional tabs subscribe without opening
parallel connections.
The page keeps an in-memory ring buffer (newest first, max 1,000) with
id or run_id:seq dedupe and resets on remount; live-only by design,
nothing is replayed on connect or persisted in the browser. Reuses the
existing event-debug filters, search, and details panel, and links each
row's run_id to /runs/:id. The category filter is the static set of
DebugCategory values so "All types" always matches.
Settings layout is now fullHeight-aware so the events page can fill the
viewport alongside the sub-nav. DebugEventDetailsPanel's event prop is
broadened to a shared EventDisplayPayload shape so it accepts both
EventEnvelope and the live payload.
