Stoat wore MongoDB's identity. Its services are named database / api /
events / …, so there is no stoat-service for updaterPrimaryImage to
match, and the fallback took the FIRST image line — mongo:8.0. Every
downstream fact inherited that: the app's version read 8.0 instead of
v0.15.1, its "8.3 available" chip was a MongoDB major dressed as a Stoat
release, its CVE scan covered mongo and none of the nine Stoat images,
and pressing Upgrade would have laddered the database 8.0 -> 8.3 beneath
a live sixteen-service stack.
The compose already says which image is the app's: every image line
carries a #LIBREPORTAL|<KEY>_VERSION_TAG| marker, and the one keyed on
the BARE app name (STOAT_VERSION_TAG, not STOAT_MONGO_VERSION_TAG) is by
construction the app's own version. 37 of 38 apps have exactly one; only
libreportal lacks it, and the scan skips that app anyway.
Ask the sentinel first, keep <slug>-service and first-line as fallbacks.
Verified across the catalogue: identical anchor for every app except
stoat, which is corrected. This is the ollama mislabel of P0 recurring
through a different hole — positional guessing — closed with the
metadata that was already there.
