webuiUpdaterScan now tells the truth instead of hardcoding update_available=false.
Per app it resolves three facts (see roadmap §2): the running RepoDigest (one
`docker inspect` of the anchor image), the display version (OCI label →
versioned tag → channel·shortdigest), and — throttled — the registry's current
index digest for the channel tag (`docker buildx imagetools inspect`, the same
identity as RepoDigest, verified exact). update_available = the two digests
differ. Emits type (versioned|rolling), channel, current/available digests +
versions, and a services[] array (every image line, anchor flagged).
- Registry lookups throttled separately from the scan: CFG_UPDATER_REGISTRY_
INTERVAL (min, default 360; 0 = local-only), own /tmp stamp, reuse of the
prior available_digest between windows so the app list still refreshes every
scan. UPDATER_REGISTRY_FORCE=1 forces a live pull (the Check-now button).
Registry failure (offline/rate-limited) = "unknown", never a false "changed".
- Digest-compare fully detects rolling apps' new builds; for versioned apps it
catches rebuilds of the pinned tag (newer-version enumeration is a later
step) — honest per type, and versioned apps are user-picked via P1b anyway.
- Fixes a P1b regression: updaterPrimaryImage now strips the trailing version
sentinel comment (`s/ #.*//`) via _updaterCleanImageRef — without this the
anchor ref (and the live CVE scanner's image arg) carried the comment.
- JSON built with jq for safe escaping; jq-less fallback keeps output valid.
Verified via a simulated 2-app install: navidrome → "0.62.0" (OCI label) +
detected update; rolling app → channel·shortdigest + update; throttled re-run
reuses the prior digest; all output valid JSON.
