Collapsing the three GPU call sites into one lookup moved the whole decision behind lookup('gpu', ...), but both consumers' tests still stubbed lookup with a constant. One test per file went red; three more kept passing for the wrong reason, because the stub's {} is falsy and every negative case was therefore true no matter what the template did.
The stubs now branch on the lookup name and record what they were asked, so each file guards what it still owns: the answer reaches the compose key or the role variable, and the lookup is asked for this service. The declared-flag-times-device matrix stays with the lookup's own tests, which is also where the boolean() over bool() rationale now lives, checked rather than written beside the call it protects.

Three modules reimplemented what utils.cache already offers, and each paid
for it with a suppression.
test_compose_override_services_defined carried a yaml.SafeLoader subclass
whose only job was to swallow compose's own tags, plus a noqa for the
yaml.load rule it then tripped. load_yaml_any handles !override and !reset
already, so the loader and the suppression both go.
test_compose_bind_sources_exist read default.env directly and argued in a
nocheck marker that once per session is fine. Reading it through
utils.cache.files makes the argument unnecessary.
test_gpu_gate loaded the role's vars and meta files with raw yaml over
hand-assembled paths; it now uses load_yaml with ROLE_FILE_VARS_MAIN and
ROLE_FILE_META_SERVICES, the way 50a13c755b did for the playwright
multipliers.
gpu_count drops a noqa ruff no longer raises, and the development env module
an import nothing uses, which lint-python rejects.

The role declares `gpu: true`, which resource.yml.j2 turns into a nvidia
runtime, and appends `-cuda` to the image tag so the container carries the
CUDA libraries the runtime alone does not provide. Both hang off
LIBRETRANSLATE_GPU, read through resource_filter: lookup('config', ...)
returned false for the same declaration and shipped a CPU image twice.
assert_gpu.yml asks CTranslate2 for its CUDA device count after the compose
handlers flush and fails on zero. Without it the container stays healthy and
answers every request while falling back to the CPU, which is how a broken
CUDA stack survived several deploys unnoticed. It is gated on the host
carrying /dev/nvidia0 and on IS_STACK_HOST, since the exec helper exits 64 on
swarm workers.
load_only moves to the variants so CI stays slim while a production deploy
loads every language. An empty list now drops the flag instead of passing an
empty one, whose meaning is ambiguous.
