tier1-review

Run a Tier 1 same-model multi-lens review of a completed chunk of work: dispatch independent review subagents (code-reviewer, architect-reviewer, simplify, and — when the change involves tests or a no-test claim — test-signal) in parallel with a complete five-element context package, triage findings into Critical/Important/Minor with a disposition per finding, land fixes as a separate commit, file beads for deferred minors, and emit a close-evidence line. Use when the user says "tier 1 review", "run tier 1", "three-lens review", "multi-lens review", or when a feature/refactor bead reaches the self-review-done stage and the change meets the multi-agent-review trigger criteria.
