Keep chat scroll position stable when stale top snapshots are captured during mobile message updates.
- Capture scroll anchors from the first visible message instead of always sampling the first DOM node
- Ignore stale or likely-invalid zero-position snapshots before attempting scroll restoration
- Guard bottom anchoring from interrupting user scroll unless explicitly forced and add regression coverage for stale snapshot behavior

Ensure Rooms scope reliably re-anchors to bottom on re-entry without breaking scroll preservation during refetch.
- reset stale thread anchor state when entering Rooms without an active room
- treat direct↔rooms transitions as entry events and anchor messages to bottom on entry
- keep existing scroll position when room messages are refetched in-place
- add regression tests covering room re-entry anchoring and refetch scroll preservation

Prevent the chat composer from showing a right-edge scrollbar line before it reaches the autosize cap.
- set chat textarea default overflow to hidden in ChatView CSS
- add resolveChatInputOverflowY to switch overflow to auto only past the 640px cap
- apply overflow mode during composer autosize updates
- extend chat input autosize tests and docs to cover overflow behavior

When the user clicks 'Latest' while loadMoreMessages was in-flight,
the scroll restoration (which maintains position when older messages
are prepended) was undoing the explicit jump-to-bottom.
Fix: clear scrollRestoreSnapshotRef and set isUserScrollingRef=false
before anchorToBottom so the layout effect's restoration is skipped.
- Remove fetchAllMessagesInChat/fetchAllMessages helpers
- Keep limit:50 for initial load in useChat and useQuickChat
- Add IntersectionObserver sentinel at top of ChatView message list to
trigger loadMoreMessages() when user scrolls to the top
- Keep stale-session guards (activeSessionRef checks) from original PR
- Tests: revert assertions back to { limit: 50 }
ChatView and QuickChatFAB both had an iOS-specific onTouchStart on the
textarea that called event.preventDefault() and then programmatically
re-focused the input — meant to suppress iOS's visualViewport auto-scroll
on re-focus. On Android, preventDefault on a textarea touchstart blocks
the soft keyboard from opening (programmatic focus() alone does not raise
the Android keyboard — only the default touch action does), so tapping
the main chat or quick chat composer focused the input but the keyboard
never appeared, looking like an instant dismiss.
Gate the touchstart workaround to iOS via isIOS().

Added a scroll-to-top action for the ChatView with per-message scroll behavior, styled to match the mobile design, with comprehensive test coverage for scroll-to-top behavior. Also preserves the mobile copy-action CSS selector.

FN-5389 adds dashboard resume event instrumentation: a `resumeInstrumentation` utility captures SSE resume signals, wired through `useChat`, `useChatRooms`, and `useTasks` hooks, with remount markers in `Board` and `ChatView`; diagnostics routes expose resume events for observability, documented in

Preserve chat scroll state across view transitions in ChatView, with comprehensive test coverage. The feature adds scroll position persistence logic gated behind a debug trace flag, and a full test suite covering the scroll state behavior.

Implements selective room composer restoration — the dashboard now classifies room send failures and gates composer restoration by error type, preventing spurious recovery on transient delivery errors while preserving composer state only for actionable failures. Covers the new classification logic i

Adds direct thread viewport write functionality to ChatView with corresponding mobile keyboard regression test coverage, plus lint and test suite restoration.

Merges FN-5218: adds hash mention support (`#`) in chat composers, grouping task and file reference results in a unified popup, with wiring into `ChatView` and `QuickChatFAB`, plus test coverage and docs. The hook `useFileMention` is extended and refactored, and the file mention popup UI is updated

- Add project-scoped Pause All Agents and Resume All Agents actions to the AgentsView controls menu
- Load bulk-action eligibility on menu open and skip ephemeral or ineligible agents
- Surface bulk action confirmations, success/error toasts, and refresh agent state after updates
- Add dashboard tests and agent docs coverage for the new bulk controls

This merge introduces SWR-style caching across the dashboard to eliminate redundant fetches for models, agents, and skills, significantly refactoring ChatView.tsx (reduced by ~140 lines) by offloading cache coordination to three new dedicated hooks (`useAgentsMapCache`, `useDiscoveredSkillsCache`, `

Reorders ChatView's input handler to resize the textarea before the
controlled setMessageInput call (matching QuickChat) so the height
assignment lands in the same frame as the keystroke and isn't lost to
React 18 batching. Also adds a 40px floor to clampChatInputHeight so a
0-scrollHeight measurement can't collapse the composer to zero.

- Linkify task detail, review, workflow, chat, activity, agent, dev server, and settings sync outputs so workspace paths open in the file browser
- Preserve inline code styling when wrapping detected paths and extend FileBrowserModal handling for linked navigation
- Cover the new linking behavior with dashboard tests and add a changeset plus AGENTS guidance for the reusable pattern
