Five apps (mastodon, owncloud, mattermost, matrix, stoat) took their generated secrets from the compose-side generator tags PASSWORD_TAG_<n>/RANDOM_TAG_<n>/ HEX_TAG_<n>/VAPID_TAG_<n>. Those mint a fresh secret on every templating run, so a reinstall handed the app a new database password while its data volume kept the one initdb was given, and the app came back up unable to open its own database. Move them to <app>.config as RANDOMIZED* placeholders, reaching the compose via the #LIBREPORTAL|<APP>_<KEY>_TAG| mechanism tags_processor_app_config_values already provides. No new handler: the tag name is derived from the config key, so this is a config line plus a tag per secret. Generation is unchanged — still random on first install; the value is now remembered instead of re-rolled. Also fixes two things this exposed: - The RANDOMIZED* replacers matched unanchored. `sort -u` orders slots lexically (1, 10, 11, 2), so slot 1's pattern rewrote the prefix inside slot 10's placeholder and slots 10+ ended up holding slot 1's secret with a digit glued on — derivable, and invisible because the values weren't byte-identical. Anchoring with \b makes match order irrelevant. Verified at 20 slots across all four placeholder types: 64 keys, 64 distinct values, no prefix collisions. - generateRandomPassword drew from base64 without constraining the mix; measured over 2000 draws, 1 in 40 contained no digit at all. Retry until the result has both a digit and a letter, bounded so a pathological length can't spin. owncloud gains a fix in passing: its compose seeded the admin account from PASSWORD_TAG_2 while the WebUI displayed CFG_OWNCLOUD_ADMIN_PASSWORD, which was generated separately and never used. Both now read the same value. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
