Review one axis: whether a Go diff follows RULES.md and applicable language contracts. Catalog rules carry aggregate support; version findings cite /golang official contracts, not taste.

Run standalone or inline as the golang hat in /review. Reviewer lanes still require explicit delegation or /swarm.

Exclude

Anything target golangci-lint config already enforces.
Generic style without catalog/version-contract backing.
Frontend, vendored, and generated *.pb.go, *_pb.go, *.connect.go, @generated/DO NOT EDIT.
Catalog debate; submit feedback rather than invert a rule.

Procedure

Scope: diff fixed point to HEAD. Inspect Go/proto plus go.mod/go.work when toolchain may change. Read .golangci.yml; exclude enabled lint rules.
Classify: proto/API, public SDK/library, handlers, Temporal, controllers, tests, config/rollout, tenant security, concurrency/lifecycle.
Load: matching RULES.md and /golang domain files: PROTO-API, CONCURRENCY, ERRORS, TESTING, TEMPORAL, SECURITY, ROLLOUT, STRUCTURE, CONTROLLERS. For Go 1.27 generic methods, compatibility, or leak profiling, load GO-1.27.md. Apply in-scope S/A rules, clear B violations, and only plain C/D violations; gate release contracts by module version/surface.
Check tensions: positive bool versus fail-closed, enum subset, keepalive, filters. Context decides.
Report: rule/contract id, file:line, behavior, required change, priority. Hat limit 400 words; standalone stays concise and sourced.
