Dropped eager todo snapshot displacement from tool_execution_start, streaming message_update, and the rebuild assistant-iteration step. Displacement now runs only when the next todo's successful result lands, so a failed follow-up leaves the last-good todo panel on screen.
Added regression coverage for the failed follow-up case and updated the streamed-second-todo test to drive displacement from the success result.
Fixes#3516
Resolved any tracked todo snapshot before storing a fresh one in the rebuild paths so an assistant message replaying multiple todo tool calls collapses to the final snapshot.
Added a renderSessionContext regression test for two todo tool calls in one rebuilt assistant message.
Fixes#3516
Kept successful todo result blocks live until a later todo update replaces them or the turn ends.
Added regression coverage for same-turn todo snapshot replacement after intervening tool output.
Fixes#3516
Tail appended transcript JSONL instead of rebuilding rendered history on every poll, collapse compacted history for live chat rendering, and replace synchronous session rewrites so tailers detect historical changes.
Fixes#3258
- Centralized draft state and image management by migrating fields from context to the CustomEditor component.
- Standardized transcript row construction by introducing shared helpers for background jobs, IRC traffic, and file mentions.
- Refactored redundant UI logic and helper functions into reusable utility modules to streamline message submission and component rendering.
- Standardized event handler types by consolidating lifecycle definitions into a shared module while maintaining public API stability.
- Added a `proseOnlyThinking` configuration setting to suppress raw code blocks in AI thinking traces.
- Implemented `formatThinkingForDisplay` utility to replace code blocks with ellipses in the UI.
- Integrated runtime toggling and live refreshing of message components via streaming reveal controllers.
- Added a live tokens-per-second indicator to the assistant thinking pulse.
- Verified logic with new unit and integration tests for thinking block presentation.
- Added `display.cacheMissMarker` setting to enable visual indicators for prompt cache invalidation in assistant messages.
- Included updated theme symbols to represent cache misses across supported icon sets.
- Configured the selector controller to rebuild the chat display when the marker visibility setting is toggled.
- Implemented `detectCacheInvalidation` to identify when model requests lose their prompt cache.
- Added `CacheInvalidationMarkerComponent` to display a slim notice above affected assistant turns.
- Updated `ChatTranscriptBuilder` and `EventController` to track session usage and inject markers dynamically.
- Included comprehensive test coverage for invalidation detection logic and UI rendering.
- Refreshed all injected message frames with a consistent rounded-outline card design.
- Implemented icon-tagged headers for hooks, local skill invocations, and generic custom messages.
- Updated skill invocation cards with home-shortened paths, dynamic line count units, and compact invocation argument display.
- Unified branch summary styling with compaction banners to provide a consistent visual language for history collapse points.
- Removed leaked absolute home directory paths from skill metadata displays.
- Fixed an alignment issue where the transcript body was incorrectly offset by an extra gutter column relative to the "Agent Hub" title.
- Updated the transcript renderer to omit the redundant outer gutter and ensure file-mention rows include the standard 1-column left pad.
- Added regression tests to verify consistent gutter alignment and correct scroll behavior.
- Replaced inline chat view with a dedicated fullscreen `AgentTranscriptViewer` overlay.
- Introduced `ChatTranscriptBuilder` to enable non-incremental, full-history transcript rendering.
- Implemented robust state management for thinking blocks, message history, and transcript disposal.
- Added support for auto-reloading local session files and sync for remote transcript data.
