Reconciliation workflow (schedule + workflow_dispatch): lists live branches and
every container version across the four images this repo builds (fleet-boot,
fleet-ipxe, fleet-dnsmasq, spdk-nvmf) and deletes dev/branch builds whose branch
no longer exists, via the Gitea Packages API. Not event-driven, so it catches
branches deleted any way and never depends on a 'delete' webhook.
Safety (per request — never touch release tags or latest):
- Only tags ending in the dev commit-sha suffix '-<7 hex>' are ever candidates.
Release/version tags (1.2.3, v1.2.3, spdk v24.09, dnsmasq main-<sha>) and
'latest' never carry that suffix, so they're structurally out of scope; there's
also an explicit 'latest' skip. Verified by simulation across representative
tags incl. spdk's <ver>-<branch>-<sha> form and pre-release semver.
- Keeps any image whose sanitized branch is still live (+ always 'main'); branch
sanitization mirrors the build workflows.
- Fail-safe: aborts before deleting anything if the live-branch list can't be
fetched (0 branches), so an API/auth blip can't trigger mass deletion.
- Conservative matching: a suffix collision only ever causes a KEEP.
DRY RUN by default: workflow_dispatch previews unless dry_run=false; scheduled
runs dry-run until armed via repo variable REGISTRY_GC_ENABLE=true (so a
scheduled dry-run can be eyeballed first). Uses the existing PACKAGE_TOKEN
(write:package). shell: bash (runner defaults to sh).
