- Updated session initialization to retrieve claude_session_id instead of sdk_session_id.
- Removed redundant comments and code related to sdk_session_id handling.
- Simplified session creation logic by directly using values from the database.
- Cleaned up message handling logic to focus on assistant messages and removed unnecessary checks for system init messages.
- Added logging of received content length and a preview for debugging purposes.
- Introduced detailed logging for summary parsing, including flags for summary components.
- Improved warning logging when no summary tags are found, including a content sample.
- Updated success message for stored summaries to be more descriptive.
- Added `claudeSessionId` to the `ActiveSession` interface to store the real Claude Code session ID.
- Updated session initialization to fetch the real Claude Code session ID from the database.
- Modified session creation logic to ensure the real session ID is used consistently throughout the worker service.
- Adjusted message generation to utilize the real session ID instead of a placeholder.
The worker was still returning 404 "Session not found" when trying to add
observations or summaries. This happened if:
- Worker restarted (sessions lost from memory)
- Race condition where observations arrive before /init
- Session continued after /exit
Changes:
- handleObservation: Auto-create session if not in memory map
- handleSummarize: Auto-create session if not in memory map
This completes the "no validation" philosophy: worker accepts any session_id
and auto-creates the session state if needed. Saves ALL data without blockage.

Root cause: Hooks provide session_id as the source of truth. We were adding
unnecessary validation (checking if sessions exist, checking status, etc.)
which caused 409 conflicts when continuing sessions after /exit.
Changes:
1. worker-service.ts: Removed 409 "Session already exists" check in handleInit
2. SessionStore.ts: Made createSDKSession idempotent using INSERT OR IGNORE
3. new-hook.ts: Simplified to just call createSDKSession - no findActiveSDKSession,
no reactivateSession logic, no status management
4. save-hook.ts: Removed session validation, use fixed port instead of session.worker_port
5. summary-hook.ts: Removed session validation, use fixed port instead of session.worker_port
Philosophy: Hooks manage lifecycle, we just save data with whatever session_id
they give us. No validation, no status checks, no guessing.

Changed summary prompts to generate discrete per-request summaries instead of cumulative session summaries. This provides better chronological memory where each summary is a clean unit representing one request/response cycle.
Changes:
- Renamed buildFinalizePrompt() to buildSummaryPrompt() in src/sdk/prompts.ts
- Updated prompt text to focus on "THIS REQUEST" rather than "this session"
- Updated all import and function call sites in worker-service.ts and worker.ts
- Added IMPORTANT warning to emphasize request-level scope
Expected behavior: Each summary will now describe only what happened during that specific request, eliminating cumulative recaps.
