Ensure the first Quick Chat message reliably streams even when a stale sendMessage closure sees no active session.
- trigger a microtask flush for queued pre-session sends when a session is already active and no stream is running
- preserve existing streaming guards so flush only runs when safe
- add regression coverage for stale-closure first-send flow to verify stream start and completion behavior

Ensure a user's first quick-chat message is preserved and sent once session initialization finishes.
- queue pre-session text sends as promise-backed pending work instead of returning early
- flush queued text after session activation and wire completion/rejection to the original send promise
- clear queued completion state on stream reset paths and add regression coverage for first-send-before-init flow

Fixes chat hooks to flush queued messages when recovery completes, preventing stale messages from lingering in useChat and useQuickChat; includes tests for both hooks.
Fusion-Task-Id: FN-4381
Removed queued warning toasts from chat queueing flows in `useChat` and `useQuickChat` hooks, with corresponding test coverage for the queueing behavior without the toast.

Merged branch adds FN-3759 queue flush ref fixes for `useChat` and `useQuickChat` hooks (with expanded regression test coverage), extracts the roadmap UI into a standalone plugin with schema hook and store bootstrap, ships FN-3281 review revisions with dashboard/plugin integration updates, and resol

Six new tests covering the three bugs fixed in the previous commit:
- Retry limit: stops showing toasts after 3 consecutive failures,
resets counter on success
- Skip flag: startFreshSession sets/clears skipNextSessionInitRef,
creates new session even when existing one exists
- Ref stability: switchSession reads activeSession from ref so it
correctly detects "same session" and skips re-initialization

This merge adds done-payload snapshot handling across the chat system (FN-3430), normalizing how final assistant messages are preserved and consumed in the dashboard hooks, plus it normalizes dashboard mailbox and user identity for inter-agent messaging (FN-3484) and introduces plugin workflow step

Merges FN-3336 to recover chat streaming state on page reload — adds `isGenerating()` and `getGeneratingSessionIds()` to `ChatManager`, enriches the session API to surface active-streaming sessions, and makes `useChat` and `useQuickChat` hooks restore the `isGenerating` flag when loading existing se

Merged FN-3207, FN-3212, and FN-3242: removed runtime memory-backend side-loading in core, added comprehensive regression tests for QuickChat, chat routes, and SSE streams, and documented compact mobile chat dialogs in the dashboard guide. The refactor in `project-memory.ts` reduces complexity while

The merge adds a `/clear` command to both the Chat view and Quick Chat that clears transient chat state on session resets, with tests for all new hooks and components. It also persists session banner dismissals via a new `useSessionBannerPref` hook, adds a hide-banner setting, and preserves planning

- Keep active streaming responses alive when resuming an existing quick chat session instead of resetting stream state
- Update useQuickChat session-resume logic to only restart waiting indicators when appropriate
- Adjust QuickChatFAB waiting indicator behavior so it reflects real in-flight assistant activity
- Add focused hook and component tests covering same-session resume and waiting-indicator regressions

Production typecheck (tsconfig.json + tsconfig.app.json) was already
clean, but a third config that includes test files surfaced 661 errors
across 60+ test files — accumulated drift between mock fixtures and
production types. Six parallel typescript-pro agents fixed every one
without touching production code.
Per-scope before/after (errors → 0):
ChatView 183
Mailbox + Agent suite (5 files) 156
Task / Modal suite (6 files) 127
App + small components (12 files) 96
Hooks + api/auth (8 files) 48
Long tail (32 files) 51
-----------------------------------------------------------------
Total 661
Major fix categories:
- Untyped state objects inferring `never[]` / `null` literals (root
cause of ~120 errors in ChatView alone — added a single
`UseChatReturn` annotation)
- Mock objects missing fields that became required: `WorkflowStep.mode`,
`ChatMessage.thinkingOutput / metadata`, `ChatSession.projectId`,
`Task.log`, `ProjectHealth` fields, `PtyTerminalSessionInfo.createdAt`,
`Agent.metadata`, `InboxResponse.total`, etc.
- Mock objects with stale fields that no longer exist:
`AgentBudgetStatus.budgetPeriod`, `truncated` on log responses,
`OutboxResponse.unreadCount`, `MergeResult.source/target/details`
- Modal props that became required (e.g. `PlanningModeModal.onTasksCreated`)
- String literals not in narrowed unions (`Column`, `WorkflowStepPhase`,
`InsightStatus`, `AgentLogType`, etc.)
- `querySelector` returning `Element` cast to `HTMLElement` for
`@testing-library/react`'s `within()`
- Vitest mock typing: `.mock.calls` access needing `vi.mocked(...)`,
zero-param tuple handling, generic `vi.fn(() => [])` inferring
`never[]`
Helpers introduced in test files (no shared infra):
- `makeSettings(overrides)` in ModelSelectorTab.test.tsx
- `makePromptOverrides(overrides)` in AgentPromptsManager.test.tsx
- `FileBrowserTestOverrides` type alias in FileBrowser.test.tsx
- `makeInboxResponse / makeOutboxResponse` in MailboxView.test.tsx
Verification:
- tsc -p tsconfig.json: exit 0
- tsc -p tsconfig.app.json: exit 0
- tsc -p tsconfig.test-check.json (new — includes test files): exit 0
- vitest run: 9639 / 9641 (2 pre-existing failures
in terminal-mobile-keyboard-layout.test.ts
unrelated to this work; verified via
`git stash` + run on clean HEAD)
Adds packages/dashboard/tsconfig.test-check.json to keep this regression
guard available locally — same as tsconfig.app.json minus the test
exclude.
