+# =============================================================================
+# The same leg as above, for the other forge. Both forges ship a runner family
+# (#109 added `rig forgejo-runner` beside `rig runner`), so a release that
+# evidences only GitHub evidences half of what it ships (#129).
+#
+# Three things differ from the GitHub leg, all measured against
+# forgejo.heavyduty.builders (8.0.3+gitea-1.22.0) on 2026-07-30, not read:
+#
+#   * Scope is the TOKEN's, never a flag — `rig forgejo-runner install` refuses
+#     --repo on purpose (commands/forgejo-runner-install.sh:160). The repo here
+#     is only where the registration token is minted from, and where the
+#     dispatched workflow lives.
+#   * The mint path is /repos/<o>/<r>/actions/runners/registration-token. The
+#     instance's own swagger documents /repos/<o>/<r>/runners/registration-token
+#     — WITHOUT /actions/ — and that path 404s. Do not "fix" this to match the
+#     published API reference.
+#   * There is no deregistration endpoint, so there is no removal token and no
+#     remote deregistration: `rig forgejo-runner remove` is local-only by
+#     design (commands/forgejo-runner-remove.sh:7-11) and the runner row
+#     survives in the UI until a human deletes it. The record says so rather
+#     than implying a clean remote teardown the way the GitHub leg can.
+#
+# Tokens: FORGEJO_RUNNER_TOKEN (a registration token) is used directly; else
+# FORGEJO_API_TOKEN mints one from FJ_RUNNER_REPO. Without an instance, a repo,
+# or a token source the leg SKIPS loudly and the record says it did not run.
