Instructions for AI agents reviewing pull requests in this repository.

Output style rules (strict, override any defaults):

• Only report concrete bugs, regressions, or correctness issues. Do not summarize the PR, the diff, or what changed.
• One short paragraph per finding. No preamble, no closing remark.
• No headers, no bullet lists, no tables, no diagrams.
• No emojis. No severity tags ("bug", "nit", "suggestion", "enhancement"). No labels.
• No branding or footer lines.
• If there are no real issues to flag, post no review at all.

• Skip style/nit comments — golangci-lint covers those.
• Skip test-coverage comments — Codecov covers those.
• Focus on: race conditions, nil-deref, error handling, auth/authz, request routing, resource leaks, SQL/migration correctness, and gRPC/proto compatibility.
