Outsider-perspective end-to-end review of a plan, PR, or code change that questions intent, traces the actual code path, and verifies the change does what it claims, with concise, actionable output.

Four-mantra debugging discipline that recites and applies in order: reproduce, trace the fail path, falsify the hypothesis, and cross-reference every breadcrumb before attempting any fix.

Writes canonical engineering records of fixed bugs covering root cause, mechanism, fix, validation, and how it slipped through, requiring a reliable reproduction and known cause before drafting.

Rewrites engineer-to-engineer content for engineering-org leadership and shapes it for the target channel (JIRA, Slack, async standup, email, meeting talking-points).
