Session Sync pipeline P0-P8 core completed

Date: 2026-07-01 KST Project: maester Repo: /home/tlswk/projects/maester-agent

Completed

Added session_sync/ package with Envelope/Watermark/Message models.
Added Claude Code adapter for ~/.claude/projects/**/*.jsonl; subagent sidecar logs are excluded to preserve {device}/{agent}/{session_id} dedup identity.
Added Codex adapter for ~/.codex/sessions/**/*.jsonl; developer/system messages and reasoning blocks are excluded from long-term summary input.
Added SQLite sessions_state for watermark dedup and update planning.
Added OpenRouter strict JSON distiller contract/parser and summary Markdown renderer.
Added Maester ingest/update executor and rolling local session_index.
Added shared reconcile service used by CLI, watcher, and HTTP API.
Added foreground polling watcher with debounce (scripts/session_sync_watch.py); no scheduler/service/cron/routine was created.
Added HTTP endpoints: GET /api/maester/session-sync/index, POST /api/maester/session-sync/reconcile.
Added docs: docs/SESSION_SYNC_PIPELINE.md.

python3 scripts/test_session_sync.py -> PASS: session sync P0-P8 core.
.venv/bin/python -m compileall api.py session_sync scripts/session_sync_reconcile.py scripts/session_sync_watch.py scripts/test_session_sync.py -> passed.
python3 scripts/session_sync_reconcile.py --agent codex --limit 2 -> dry plan ok.
FastAPI TestClient dry-run POST /api/maester/session-sync/reconcile -> 200, decision_counts {'ingest': 1}.
FastAPI TestClient GET /api/maester/session-sync/index -> 200.
python3 scripts/session_sync_watch.py --agent codex --once -> exits cleanly.

Hermes adapter requires a real message-bearing session schema. Current /home/tlswk/.hermes/sessions/sessions.json exposes session metadata/origin/token counters, not message history.
OpenClaude adapter remains blocked because no local OpenClaude session root was found in this pass.

Existing dirty data/action_lifecycle_audit.jsonl was present and left untouched.
