Answers a direct question from this session: no, reinstalling
asterisk/mattermost did NOT fix a coturn user missing from the live
database, because ensure_coturn_user() only ever calls turnadmin -a in
the else branch — reached only when the cache file (users/<consumer>.env)
is MISSING. A stale-but-present cache file (exactly what a coturn
container/volume recreation without preserving ./db leaves behind, per
this session's real diagnosis) looked identical to a healthy one and was
trusted blindly, so every consumer's installer kept silently reusing
credentials that no longer existed in coturn's database.
Now checks the cached username against coturn's actual live user list on
every call, and re-registers it with the same cached password if it's
missing — the same self-heal pattern this repo already applies elsewhere
(Beszel's compose patch, Vaultwarden's SMTP half-state, FMD's chown).
Re-uses the turnadmin -l log-noise filter from tools/coturn-test-check.sh
(a real "user[realm]" line never contains a space; at least one coturn
build writes its own startup log lines to stdout, not stderr, so a bare
2>/dev/null doesn't catch them).
