fix: hide empty-state copy on queue credential fail-closed (Closes #458)

-## 31B. Mutation-capability table (#405)
-
-Every performed mutation requires exact capability proof resolved **before** that
-mutation executes. Nearby capabilities never authorize a different operation —
-`review_pr` does not authorize `merge_pr`, and `merge_pr` does not authorize
-`delete_branch` / `gitea.branch.delete`.
-
-When any mutation beyond a bare review occurs (merge, branch delete, issue
-close/comment, etc.), the final report must include a **mutation-capability table**
-with one row per performed mutation:
-
-* mutation (tool/action name)
-* exact task/capability resolved (for example `merge_pr` / `gitea.pr.merge`)
-* result
-* order/timestamp proof that capability was resolved before the mutation
-
-If exact capability proof is missing, skip the mutation or stop the workflow —
-never claim a performed mutation without its row. Post-hoc capability proof after
-the mutation fails validation.
-
 ## 31A. Local artifact and report consistency rule
 
 Do not create local walkthrough, notes, markdown, JSON, or report artifacts during reviewer runs unless the canonical workflow or operator explicitly requires it.

-### 10A. Duplicate-work gate phases (#400)
-
-Before any file edits, prove duplicate-work clearance with
-`gitea_assess_work_issue_duplicate` or `gitea_lock_issue` (which runs the same
-gate). The gate checks live:
-
-* open PRs linked to the issue (head branch or Closes/Fixes reference),
-* remote branches matching `issue-<number>`,
-* active claim leases from structured heartbeats.
-
-Re-check immediately before:
-
-* `gitea_commit_files` (commit),
-* branch push,
-* `gitea_create_pr` (PR creation).
-
-If a concurrent open PR appears after work begins:
-
-* before commit/push → stop and preserve local work without pushing,
-* after commit but before push → stop without pushing,
-* after push but before PR creation → stop and produce a reconciliation
-  handoff instead of opening a PR.
-
-Final reports must state exactly one duplicate-work outcome:
-
-* `duplicate PR prevented`
-* `duplicate branch prevented`
-* `duplicate commit prevented`
-* `duplicate work not prevented`
-
 ## 11. Claim or lock the issue before implementation
