kevinveenbirkenbachandClaude Opus 5 5137465c6f style: delete every comment the comments-valid policy rejects
3529 invalid comments in 528 files, grandfathered in while the linter
only saw the working-tree diff. Removal ran through the linter's own
collectors, so detection and deletion cannot drift: a comment whose
opener line is blank before it and whose closer line is blank after it
loses all its lines, anything else loses only the comment region, and a
line left holding a bare delimiter goes with it.

Five files keep their comments behind a nocheck marker instead. Four are
upstream configs whose inline docs are upstream's own (mautrix, systemd
journald, nextcloud-oidc-login, MediaWiki). In littlejs the
commented-out entries ARE the deactivation mechanism for an example
tile, so deleting them would delete configuration.

Usage:
{{ lookup('container_hostname', application_id) }}
The Docker/OCI hostname for an application's container: its canonical
primary domain when that fits the kernel's 63-byte limit, otherwise the
short entity name (e.g. ``xwiki``). Centralises the domain-or-entity
choice so onion deployments (long ``.onion`` subdomains that overflow
sethostname(2)) never break container init.
