A client's git-lfs derives its LFS endpoint from the proxy URL, so the proxy must answer the batch API and object transfers or LFS-tracked files fail to check out. Proxy the batch API upstream, rewrite each download URL back to the proxy, and serve objects from a content-addressed cache: a miss fetches once (verifying sha256 == oid), a hit is served locally, and objects share the mirrors' cache cap and LRU eviction. Uploads are refused (read-only). The LFS transfer is in-process over rustls (no OpenSSL), keeping the binary static. Assisted-by: Claude:claude-opus-4-8
The record_*/observe_* helpers took plain &str for the kind/op/result labels, so a typo compiled and only surfaced as a wrong metric series. Type those arguments with enums (RequestKind, Status, UpstreamOp, ServeKind, LfsResult) that render to the label string, keeping the free-form repo path a &str. Assisted-by: Claude:claude-opus-4-8
Pin the Codecov patch bar at 90% and require project coverage to never drop (0% tolerance), so a change can only hold or raise the line - matching the floor ci.yml enforces via --fail-under-lines. Assisted-by: Claude:claude-opus-4-8
