kevinveenbirkenbachandClaude Opus 5 acc9e25c0f refactor(volumes): one canonical mount surface, context-wired lookups
The mount pipeline was split across two layers: compose_volumes and
container_volumes lived as filter modules that ansible's filter loader
rejected on every start ("has no attribute 'FilterModule'", two warnings
per run), while the same-named lookups wrapped them thinly. The filter
bodies now live inside their lookups (the tor_socks precedent), the
filter files are gone, and the render tests moved next to the lookup
tests.

As lookups they see the templating context, so the application_id term
every call site passed back to its own role is gone too: both lookups
read application_id from context and fail loudly when it is missing.
107 templates and nfs_prep.yml drop the term; the calls collapse to
lookup('compose_volumes') and lookup('container_volumes', service_name).

The container_volumes call is now canonical - four leading spaces,
service_name in the service position, | indent(4) - enforced by a new
lint (test_container_volumes_call_shape). Normalizing the 85 literal
call sites surfaced that erpnext keyed its meta/volumes.yml mounts by
container name instead of compose service key, the only role to do so;
its meta now uses the service keys. wordpress's column-0 call, which
rendered its first line at top level, is indented like every other.

Template logic that only restated meta/volumes.yml is deleted: mailu fed
compose_volumes an extra_volumes dict whose eight names were looked up
from the very meta file compose_volumes reads itself; zammad's init and
railsserver extra mounts were the volumes.yml entries minus the two
services, which the meta now lists (the when-gated OIDC binds included).
Conditionality that meta cannot express stays in code, but in role-local
lookup plugins instead of template loops: matrix_bridge_mounts renders
the per-bridge registration mounts, nextcloud_extra_volumes the
feature-gated whiteboard/recording volumes (type: volume entries are
declared unconditionally by compose_volumes, so gating must happen
before it).

Parity is proven, not assumed: every mechanically rewritten template is
byte-identical to HEAD after the transformation regexes (95/95), and the
semantic roles render identically through the real functions against
HEAD's meta - zammad across six sso/tls polarities, all seven erpnext
services, mailu's top level. make test-lint passes complete.

Also: suitecrm's compose template pins container_extra_hosts with
host_alias (the SOCKS proxy URL host.docker.internal never resolved in
compose+tor), and the five disabled mautrix bridge addons use the
empty-default config lookup so templating the applications dict stops
emitting 125 errors per batch in every CI job.
