* fix(app): keep timeline history and previews stable
Treat persisted timeline replicas as display-only so authoritative pagination always comes from the daemon. Require renewed user intent between older-history pages unless the viewport genuinely remains at the history edge.
Model assistant image acquisition as loading, loaded, or failed so recreating a preview URL cannot be rendered as an error.
* fix(app): keep file image previews current
* fix(app): stabilize history pagination edges
* fix(app): recover transient timeline loads
* fix(app): retain assistant image previews
* Stabilize history pagination lifecycle
* Stabilize history settlement and image previews
* Retry file images after reconnect
* Keep active previews and pagination requests alive
* Replace image hook tests with typed ports
* Integrate timeline hydration with submission authority
* Harden pre-hydration timeline reconciliation
* Make rewind E2E use real scroll intent
* Preserve live timeline state through hydration
* Keep mounted image attachments retained
* Protect preview persistence and lifecycle hydration
* Preserve idless live assistant continuations
* Preserve timeline rows across delayed hydration
* test(app): cover real assistant image files
* Preserve assistant tool ordering during hydration
* 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.
Keep a small non-authoritative view of the last focused chat so the app can paint it before the daemon finishes revalidation. Bound persistence to one focused agent per host and evict whole host entries to limit storage and serialization work.
