* fix(app): stop completed turns from appearing stuck
Turn activity was inferred from a user-message row flag, so a stale duplicate row could keep the working footer active after the turn ended. Track submission lifecycle separately and route every send path through the shared submission flow.
* fix(app): guard pending message identity
* test(app): measure submission layout independent of scroll
* fix(app): keep submitted messages consistent through reconnects
Track each in-flight send until its own RPC establishes acceptance, and keep canonical timeline placement authoritative. Restore legacy cached rewind IDs during cache deserialization.
* fix(app): close canonical submission races
* test(app): cover canonical submission races in browser
* fix(app): keep replacement submissions authoritative
Keep current pending rows out of legacy cache migration and leave ambiguous terminal lifecycle events to the daemon snapshot. This prevents fabricated rewind identities and stale completion events from marking replacement turns idle.
* fix(app): keep submitted messages stable across sync
Give submission transport and canonical timeline ingestion separate authority. Preserve every unresolved local send across replacement, reconcile provider identity once, and bridge RPC acceptance to authoritative running state without deriving lifecycle from timeline rows.
* fix(app): settle submissions in either acknowledgement order
Complete submission transactions when RPC and provider acknowledgement arrive in either order. Cache only transaction-owned local rows as transient data, preserve canonical ID-less prompts, and invalidate ambiguous legacy display caches instead of inventing provider identity.
* fix(app): keep agent visible during history handoff
Running and terminal updates could clear create continuity before the initial authoritative timeline arrived, leaving a streaming agent behind the loading screen. End the handoff only when authoritative history is applied.
* fix(app): settle attachment-only submissions
Canonical providers can acknowledge image-only prompts with empty text. Reconcile those events by client identity without rendering a blank canonical row.
* fix(agent): settle out-of-band message submissions
Accepted commands that do not allocate a foreground turn previously had no canonical user acknowledgement. Record the command before its handler runs so submission state and reconnect history converge through the normal timeline producer.
* fix(app): settle out-of-band submissions compatibly
* fix(app): preserve canonical prompt order
* test(app): keep workspace status check timing-independent
The workspace-status scenario asserted footer settlement before initial agent creation had necessarily completed. The dedicated draft-handoff coverage owns that lifecycle contract.
* feat(sync): keep live data scoped and current
Only viewed chats receive live timeline rows, while directory state now uses one subscribed bootstrap followed by ordered deltas. Legacy clients and daemons retain their existing behavior through centralized compatibility gates.
* fix(sync): preserve selective delivery boundaries
Keep selective timeline capability app-owned, union viewed sets across shared sockets, and reconcile directory side effects from accepted state. Visibility and archive suppression now follow their existing authoritative boundaries.
* test(app): align browser fixtures with runtime contracts
* fix(sync): preserve mixed-client delivery guarantees
* fix(sync): finish paged history before advancing
* fix(sync): replay live deltas after refresh failures
* test(server): model socket capability lookup
* test(app): use platform shortcut for split-pane coverage
* fix(app): keep hidden timelines dormant
* test(app): normalize split-pane shortcut setup
* fix(app): preserve sync state across retries
* fix(app): preserve background sync state across races
* fix directory bootstrap reconciliation edge cases
* fix selective timeline compatibility races
* fix superseded directory sync races
* fix(sync): centralize directory replica ordering
Own agent and workspace refresh transactions in HostRuntime so reconnect epochs, buffered updates, and lifecycle invalidation share one ordering boundary. Route timeline metadata and mixed-capability stream delivery through their authoritative runtime sources.
* fix(app): keep timeline requests runtime-scoped
* fix(app): close directory bootstrap races
