Summary
Adds generic build-cache operation observation hooks to the Blacksmith bazel-remote fork. This is intentionally FA/Web agnostic: bazel-remote only forwards opaque labels and semantic cache outcomes.
Metric contract
action_cache_get:hit | miss | errorcas_lookup:hit | miss | errorbackend_upload:error | droppedClient transfer bytes are not inferred in bazel-remote. FA observes gRPC payloads and emits
client_upload/client_downloadrows.Safety
