 ## Active Policy
 
 - Put coordination notes and handoffs in this `sync/` folder and push to Gitea.
+- Check sibling project sync folders first when context may span repos.
 - Use TIPLLM only for TIP crawler/robot planning and extraction feedback.
 - Write robot/crawler experience into the Gitea-backed TIPLLM training pool.
 - Keep Erik safe: no heavy crawler waves or uncontrolled Playwright/discovery jobs on Erik.
 - Use Proxmox/Pi workers for crawl load.

 ## Dirty Worktree Note
 
 There are existing uncommitted changes outside `sync/`. Some are Codex work from this session, some appear pre-existing or from earlier Claude/Codex work. Do not blindly revert them. Review `git status --short` before committing broader changes.

+# 2026-04-29 Cross-Repo Sync Note
+
+Claude Code created a parallel sync handoff in the `rene/llm-gateway` Gitea repo.
+
+Observed from user screenshot:
+
+```text
+e272105 sync: add chat handoff + context scaffolding for Codex integration (2026-04-29)
+```
+
+Files shown:
+
+- `sync/README.md`
+- `sync/CURRENT.md`
+- `sync/history/2026-04-29-sync-handoff-integration.md`
+
+Important:
+
+- This TIP repo has its own `sync/` folder.
+- The LLM Gateway repo also has a `sync/` folder.
+- Future Codex/Claude sessions should check both when work involves shared Erik infrastructure, LLM routing, bridge services, authentication, TIPLLM, or crawler orchestration.
