   configured repos were not checked. This is not a complete queue inventory."
 - A single-repo "no open PRs" result MUST NOT be reported as global "no open PRs"
   if the other configured repo was not inventoried.
+- PR inventory trust gate (#196): before reporting "no open PRs" or "queue empty",
+  the workflow must run `pr_inventory_trust_gate` (via the live inventory path or
+  `review_proofs.assess_reviewer_queue_inventory`). Only `trusted_empty` allows a
+  clean empty-queue stop. Report `pr_inventory_trust_gate.status`, reasons, and
+  corroboration in the final report. A bare `[]` from `gitea_list_prs` is never
+  sufficient proof.
 
 Rules (llm-project-workflow):
 - Review in a SEPARATE detached review worktree, never the author's folder.
+- Worktree safety (#233): before checkout, diff, validation, review, or merge,
+  report the starting worktree path and whether it was dirty. If unrelated
+  tracked files exist outside the PR scope, STOP or run
+  `scripts/worktree-review <pr-head-branch>` and validate in the scratch path.
+  NEVER run `git stash`, `git stash pop/drop`, `git checkout --`, `git reset`,
+  or `git clean` to manage another session's dirty files.
+- Final report must state: Worktree path, Worktree dirty (yes/no),
+  Scratch worktree used (yes/no + path if yes), and confirm no unrelated local
+  files were modified, stashed, reset, or dropped.
 - You must NOT be the PR author. If the authenticated user == PR author, stop.
   A different LLM-Agent-SHA does NOT make you a different actor — only a
   different authenticated Gitea user does (docs/llm-agent-sha.md).
