+# HANDOFF.md
+
+## Purpose
+Immediate baton-pass for the next fresh implementation session.
+
+## Current objective
+Finish proving the Google Workspace + n8n integration through the real approval-routed path, not just direct Gog commands or dry-runs.
+
+## Use these state files first
+1. `WIP.md` — full standing plan and checkpoints
+2. `memory/2026-03-12.md` — detailed execution history and evidence
+3. `memory/tasks.json` — task status tracking
+
+## What is already true
+- `openclaw-action` is live in n8n and active.
+- Google auth via `gog` is working.
+- Local automation env lives in `/home/openclaw/.openclaw/credentials/gog.env` and should stay out of git.
+- Host bridge exists at:
+  - `skills/n8n-webhook/scripts/resolve-approval-with-gog.py`
+- Direct Gmail draft create/delete tests succeeded.
+- Dry-run n8n-routed Gmail + Calendar bridge tests succeeded.
+
+## Highest-priority next actions
+1. **Real n8n-routed Gmail draft test**
+   - queue `send_email_draft` through `openclaw-action`
+   - approve through `resolve-approval-with-gog.py` (no `--dry-run`)
+   - verify draft exists in Gmail
+   - delete the test draft
+   - update `WIP.md` and memory with result ids/evidence
+
+2. **Real n8n-routed Calendar event test**
+   - queue `create_calendar_event` through `openclaw-action`
+   - approve through `resolve-approval-with-gog.py` (no `--dry-run`)
+   - verify event exists in Calendar
+   - delete the test event
+   - update `WIP.md` and memory with result ids/evidence
+
+## Success criteria for this next session
+- both real approval-routed tests pass end-to-end
+- cleanup is confirmed (draft removed, event removed)
+- `WIP.md` reflects the new state cleanly
+- relevant memory/task files are updated
+- meaningful git checkpoint(s) committed
+
+## Relevant files
+- `WIP.md`
+- `HANDOFF.md`
+- `skills/n8n-webhook/assets/openclaw-action.workflow.json`
+- `skills/n8n-webhook/scripts/call-action.sh`
+- `skills/n8n-webhook/scripts/resolve-approval-with-gog.py`
+- `skills/n8n-webhook/references/openclaw-action.md`
+- `memory/2026-03-12.md`
+- `/home/openclaw/.openclaw/credentials/gog.env` (local-only)
+
+## Relevant branch / commits
+- branch: `feat/n8n-action-bus-v2`
+- latest checkpoints already on branch include:
+  - `afa48a3` — bridge approvals to gog executors
+  - `044e36f` — auto-load local gog automation env
+  - `06fa582` — track google workspace and n8n plan
+
+## Operator note
+Use the live n8n public API directly when it is the right path. Do not act blocked on n8n API access.
