Skipping the reconcile to keep the sweep 'read-only' was wrong. It researches a
stale checkout, and on the first real run left two recipes with no survey output
at all — indistinguishable from 'no upgrades available' unless you look. The
reconcile is safe precisely because recipe work lives in branches, not on main.
Also documents the trap that produced a false finding in that run: several
coopcloud recipes keep a stale 'main' beside the real default 'master'. gitea's
main is at 1.24.2-rootless while master has 1.27.1-rootless and the merged PRs,
so reading main reports a recipe three releases behind and missing two CVSS-9.8
RCE fixes. Resolve default_branch from the API before reading any file.
And: no output is not 'no upgrade'. It is a third outcome, and only becomes '?'
after the direct registry check has also failed.
