P1: tool_result dedup changed from "first wins" to "last wins"
- claude-client.ts: remove emittedToolResultIds Set, both PostToolUse and
user message handler emit freely. PostToolUse provides immediate UI feedback;
user handler's potentially more complete result arrives second.
- route.ts: collectStreamResponse replaces existing contentBlock entry when
duplicate tool_use_id arrives (last wins for DB persistence).
- ChatView.tsx: onToolResult replaces existing state entry by tool_use_id
instead of skipping, ensuring most complete result is displayed.
P2: SDK task ID collision risk eliminated
- db.ts: syncSdkTasks now uses full sessionId in task ID
(`sdk-{fullSessionId}-{index}`) instead of truncated 8-char prefix,
eliminating cross-session primary key collisions.
P2: Todo ordering stabilized
- db.ts: add sort_order column migration, syncSdkTasks writes array index
as sort_order. getTasksBySession sorts by sort_order ASC, created_at ASC
so tasks with identical timestamps maintain insertion order.
P3: Documentation field mapping corrected
- agent-tooling-todo-bridge.md: fix field mapping table — actual implementation
maps activeForm (not priority) to description column. Updated dedup strategy
docs from "three-layer skip" to "two-layer last-wins replace".
Lint: fix prefer-const for finalPrompt in claude-client.ts.
