+### WSL2 details
+
+WSL2 is auto-detected via `/proc/version`. The script calls `wt.exe` through Windows interop to open a new Windows Terminal tab running the same WSL distro. Claude is launched as `claude` (if installed natively in WSL via npm) or `claude.exe` (Windows Claude via interop). Process management uses native Linux tools (`ps`, `kill`). WSL-specific process names (`relay`, `sessionleader`) are recognized in the process tree.

+
+Documents the full architecture for how Claude Code sessions report status back to OpenClaw.

+
+## Overview
+
+When Claude Code finishes a context reset (or sends a manual status update), it fires a
+stop hook that flows through a chain of components to update both the local tab tracker
+and the OpenClaw main session.

+
+## Data Flow — Step by Step
+
+1. **Claude Code session ends** (or checkin is called manually mid-session)
+2. **`openclaw-checkin.js`** spawns a WSL process: `wsl -e bash -c "python3 <path> --status done --detail 'Session stop event' --project <name> --fire-and-forget"`
+   - `CLAUDE_PROJECT_DIR` env var is set by the hook runner (Windows path)
+   - Project name is `path.basename(CLAUDE_PROJECT_DIR)`, sanitized
+3. **`openclaw-checkin.py`** resolves project name from `--project` flag (or fallback: `basename(CLAUDE_PROJECT_DIR)`)
+4. **`_update_tracker()`**: Reads `tracker.json`, finds the first `active` tab whose `project_name` matches (case-insensitive substring), appends a checkin entry, updates `last_checkin`. If `status == "done"`, marks tab `completed` with `completed_at` and `summary`. Writes atomically (`.tmp` → `os.replace()`). Wrapped in `try/except` — never raises.
+5. **`_log_comms()`**: Appends a JSONL entry to `~/.openclaw/comms/claude-code.jsonl` (ts, dir, type, message, result, latency_ms)
+6. **`send_to_openclaw()`**: POSTs to the OpenClaw chat API with `fire_and_forget=True` (5s timeout). Timeouts are expected and OK — tracker is already updated.
+7. **claude-tab-monitor cron** (every 30 min): reads `tracker.json` via `manage-claude-code.py monitor`, checks `last_checkin` recency, detects stalled/dead/completed tabs, reports to main OpenClaw session.
+
+---
+
+## The Bug (Fixed 2026-04-27)
+
+### Root Cause
+
+Before the fix, `openclaw-checkin.py` only:
+- Wrote to the comms log  
+- POSTed to the OpenClaw chat API (which always timed out at 5s — LLM round-trip is slow)
+
+It **never wrote to `tracker.json`**.
+
+`manage-claude-code.py` and the monitor cron **only read `tracker.json`** — they never parsed
+the comms log or chat API responses.
+
+Result: 32 checkins in `comms/claude-code.jsonl`, all with `"result": "timeout"`. Zero updates
+to `tracker.json`. `last_checkin` was `null` for every active tab. The two sides were completely
+disconnected.
+
+### Fix Applied
+
+1. **Added `_update_tracker(status, detail, project)`** to `openclaw-checkin.py`:
+   - Called from `main()` **before** the OpenClaw API POST (tracker always updated, even on API timeout)
+   - Finds matching tab by `project_name` (case-insensitive substring match, skips non-active tabs)
+   - Appends to `checkins[]`, updates `last_checkin`, optionally marks `completed`
+   - Atomic write (`.tmp` → `os.replace()`) — safe on POSIX/WSL
+   - Wrapped in `try/except` — never breaks the checkin flow
+
+2. **Added `--fire-and-forget` to argparse** (hidden, accepted but ignored):
+   - `openclaw-checkin.js` was passing `--fire-and-forget` which caused `argparse` errors
+   - Added as a no-op flag for backwards compatibility
+
+3. **Synced both script copies**: context-reset `scripts/` → `.claude/scripts/`
+
+---
+
+## Testing
+
+```bash
+# Simulate a checkin from a project that has an active tab in tracker.json
+CLAUDE_PROJECT_DIR=/home/ubu/.openclaw/workspace \
+  python3 /mnt/c/Users/joelg/Documents/ProjectsCL1/_grobomo/context-reset/scripts/openclaw-checkin.py \
+  progress "test checkin" --quiet
+
+# Verify tracker.json was updated:
+jq '.tabs[] | select(.project_name == "workspace") | {last_checkin, checkins: (.checkins | length)}' \
+  /home/ubu/.openclaw/workspace/scripts/claude-tabs/tracker.json
+
+# Expected: last_checkin is a recent ISO timestamp, checkins count > 0
+
+# Test --fire-and-forget compat flag (accepted, no error):
+CLAUDE_PROJECT_DIR=/home/ubu/.openclaw/workspace \
+  python3 /mnt/c/Users/joelg/Documents/ProjectsCL1/_grobomo/context-reset/scripts/openclaw-checkin.py \
+  --status done --detail "test done" --project workspace --fire-and-forget
+# Expected: tab status changes to "completed" in tracker.json
+```
+
+---
+
+## Notes
+
+- The `--quiet` flag suppresses stdout/stderr output but does **not** suppress tracker writes
+- The `--wait` flag waits up to 120s for the OpenClaw API reply; default is fire-and-forget (5s)
+- Tracker writes succeed even when the OpenClaw API is completely unreachable
+- Only **active** tabs are updated by checkins (completed/archived tabs are skipped)
+- The comms log is append-only — it's an audit trail, not the source of truth for tab state
