Answers "should we stop creating an admin/pass on start" with the split the
catalog actually has, rather than one way for everything.
Ten apps need it: adguard, authelia, bookstack, matrix, nextcloud, owncloud,
pihole, rocketchat, stalwart, speedtest and headscale either pass the generated
password into the container or hand it to an install hook that creates the
account. There the password IS the working credential — dropping it would lock
you out. Left alone.
Three do not create an account at all: gitea, invidious and mattermost seed no
user (the first one comes from their own signup flow or the Create Account tool),
so the password minted at install named nothing. The WebUI credentials card
showed a password that could not log in. They now match linkding — an empty,
unslotted ADMIN_PASSWORD the auth adapter fills when the operator makes the first
admin, and keeps in step on later resets. Unslotted because the slot number marks
a value the installer generates.
mattermost's adapter also had linkding's bug: it persists ADMIN_PASSWORD but the
config declared only ADMIN_EMAIL, so the write was a no-op.
WebUI: rocketchat's generated admin password had no field mapping, so the card
could not show it. Added, plus a generic ADMIN_USER entry — six apps record an
admin username the card had no way to display.

Installing rocketchat failed with
invalid IPv4 address: ParseAddr("IP_DATA_2"): unable to parse IP
ipUpdateComposeTags allocates one IP per SERVICE_TAG_N annotation and fills
IP_TAG_i only where SERVICE_TAG_i exists. The four new apps tagged only their
primary service, so every sidecar — matrix's postgres, mattermost's postgres,
rocketchat's mongo, and fifteen of stoat's sixteen — kept a literal IP_DATA_n
in the deployed compose and docker refused to create the container.
Tag every service that carries an ipv4_address, index-aligned with its IP_TAG.
For stoat that also meant moving caddy from SERVICE_TAG_1 to _6 so the indices
line up with the IPs rather than the reading order.
mastodon had the same latent break (IP_TAG_2 and _3 untagged) and is fixed the
same way — it would have failed on first install for the same reason.
SERVICE_TAG carries the compose *key*, not container_name: 'libreportal app
restart <app> <service>' passes it to 'docker compose restart', which only
understands keys.

VAPID: the two values are the halves of one P-256 keypair, not independent
secrets — the browser verifies that a push is signed by the private key matching
the public key it subscribed with. The RANDOMIZED* generators mint each
placeholder on its own, so they produced two unrelated strings and web push could
never have worked. Generate the pair in mastodon_install_post_setup the way stoat
already does, encoded as Mastodon's webpush gem expects: unpadded URL-safe base64
of the 32-byte private scalar and the 65-byte uncompressed public point, sliced
out of the SEC1 DER. Verified by rebuilding the key from the emitted private half
and re-deriving the public point — openssl accepts it and the point matches.
Generated once and never rotated (rotation would invalidate every subscription),
but a pair of the wrong shape is replaced, so an install carrying the old
unrelated strings heals itself on next install — their public half is 42 chars
where a real point is 87.
Slots: CFG_<APP>_DB_PASSWORD -> CFG_<APP>_DB_PASSWORD_1 and likewise for
DB_ROOT_PASSWORD, across mastodon, owncloud, mattermost, matrix, nextcloud and
bookstack, so a database credential is always a numbered slot and a second one is
just _2. Renaming a key means reconciliation drops the old and adds the new
holding its placeholder, so an existing install regenerates unless the value is
carried over first — documented, including that the old file survives as
.<app>.config.bak.

Rocket.Chat tails the Mongo oplog for realtime delivery, and a standalone
mongod has no oplog — so the database has to be a replica set even with one
member.
Uses the official mongo image rather than bitnami/mongodb (which upstream's own
compose uses) because Bitnami moved its catalog behind a paid registry and the
free tags are no longer dependable for a long-lived install. The cost is that
rs.initiate() is not automatic, so the post-start hook runs it once — guarded by
rs.status() so a reinstall over restored data doesn't re-initiate a live set,
and followed by a wait for the member to report itself primary.
Mongo runs without auth: enabling it on a replica set also requires a shared
keyfile for member-to-member auth, which is a lot of moving parts for a database
that is never published outside the docker network.
