+- Verify the repo slug before issue commands. The canonical repo is `pwrdrvr/openclaw-codex-app-server`; older shorthand like `pwrdrvr/openclaw-app-server` is wrong and will make `gh issue ...` fail.
+- `gh project item-edit` needs opaque ids for the project, item, field, and single-select option. Always discover them with `gh project view ...` and `gh project field-list ...` instead of assuming cached ids still match.
+- GitHub Projects custom views are not well-supported by `gh` or GraphQL mutations. Reading views works, but creating/editing/copying views is still better done in the web UI or browser automation. `gh project copy` does not carry over custom views.
+- `.local/work-items.yaml` is currently issue-only. Add PRs to project `7`, but do not expect `pnpm project:sync` to mirror PR items into the local tracker.
+- `.local/issue-drafts/<nn>-<slug>.md` filenames are local scratch ids, not GitHub issue numbers. Keep them stable enough to reuse, but do not try to force them to match the eventual GitHub issue number.
