-  # -official doesn't run per-entry static checks (zombie, schema, binaries,
-  # etc.) so the `scan.*` axes are emitted as "skipped". The granular policy
-  # booleans (`has_broad_scope_hooks`, `has_undisclosed_telemetry`,
-  # `description_matches_behavior`) aren't surfaced by this workflow's
-  # per-entry artifact yet, so they're emitted as null; the triage
-  # `triage_bool_to_str` helper maps null → "?" so display is graceful.
-  # Status describes the execution state, not the outcome — `ran` when the
-  # scan action evaluated this SHA fresh, `cached` when a prior verdict was
-  # reused (cf. run-verdicts.json's `source` field). Outcome lives in
-  # `policy.passes`. policy-sweep.sh dispatches on this exact vocabulary.
-  #
-  # PR resolution: pull_request events carry the PR number directly. The
-  # bump workflow creates bump PRs via GITHUB_TOKEN (which doesn't fire
-  # pull_request triggers — recursion guard) and dispatches this scan via
-  # workflow_dispatch on the bump branch. In that case we look up the
-  # open PR by head ref. No PR (scan_all dispatch on main, etc.) → no-op.
