Probed every reachable surface rather than stopping at the endpoint #853 already knew 404s: the dispatch API takes `ref` as a required free-form string with no allow-list; protected environments do not exist at 1.27.1 (0 of 308 documented paths mention "environment", secrets are org/repo/user-scoped only); the loaded `app.ini` sets two `[actions]` keys; and the CLI's sole Actions subcommand is `generate-runner-token`. So option 3 is unavailable.
Accepted on a different ground than the issue proposed. "Anyone with repository write can already do worse" is unfalsifiable and hides the cheaper route. The operative reason is that dispatch is not the cheapest path: `docker-build.yml`'s head-resolved `pull_request:` runs attacker-authored YAML, which reaches every secret in the store — six of its jobs hold `REGISTRY_PASSWORD` on that route and two are branch-protection required contexts. "Push a branch, open a PR" costs no act outside the ordinary contribution flow, where a dispatch costs one.
Corrections to #853's own table, verified against the tree: `dependency-scan.yml` references no secrets at all; the "four workflows" count is right.
Deliberately not applied: a `v*` tag protection (`tag_protections` is empty and 1.27.1 supports it) — protection-class config whose failure mode is a broken release cut, so it needs its own change and verification. Tracked with the `pull_request:` residual in #885.
The web UI was not swept, and the record says so explicitly rather than claiming exhaustiveness — a Gitea Actions control can exist with no API surface at all.
