How does this work?

Each specialized expert automates some manual review task, and together the experts drive a bulk of code review work. Humans are only pulled in for judgement calls.

• Review Orchestrator — Coordinates the review lifecycle and dashboard, running the right experts initially and rerunning only those affected by significant pushes.
• Deep Code Reviewer — Reviews the diff line by line to find objective, actionable bugs with minimal false positives, then focuses on significant interdiffs and newly affected code.
• Risk Analyzer — Classifies the current change as low risk or needing human review and refreshes that evidence after significant changes; it never approves.
• Pair Reviewer — Builds a reviewer briefing covering design, architecture, security, and testing; answers questions and helps reviewers draft comments.
• PR Author / PR Fixer — PR Author maintains PRs it creates; PR Fixer handles repairs for PRs created without PR Author.
• Verifier — On cosmos verify, exercises applicable runtime behavior end to end and reports the evidence.

Your role

• Complete the Pair Review and supply intent, history, and judgment unavailable from code.
• Skim linked Verifier evidence when available; otherwise test manually.
• Skim author and Fixer decisions about what changed or remained unchanged.
• Make the final merge decision and merge the change yourself; no expert merges it.

_{The Review Orchestrator incrementally reruns applicable code reviewers on significant new commits.}

this is staging only. remove

Good catch — removed. cosmos_desktop_ui is staging-only (off in prod), so it shouldn't be in the changelog.

Risk: Low risk · head bf8c8a0

Why?

The entire change is a documentation-only update to CHANGELOG.md (+15/-0) adding user-facing v0.34.0 release notes, with no executable code, migrations, schemas, auth, billing configuration, or generated files. The content is a plain product changelog and contains no AI prompts, prompt templates, or review guidelines, so it falls squarely in the documentation-only low-risk category. The staging-only line flagged in review was already removed at the current head, leaving nothing with runtime impact. A human could not realistically add value by reading this diff.
