Resolves a single bug from any starting evidence — Dash0 telemetry (span, log, web event, RUM error link), a stack trace, an error message, a code pointer (file:line), a screen recording, a Linear ticket URL, or a free-text symptom. Classifies the input, triages complexity (Phase 0.5) to pick a fast lane or a full holistic-analysis lane, runs a pre-flight sweep, locks a failing reproduction (delegating to /tdd, /e2e-testing, or /e2e-testing-mobile by layer), delegates root-cause analysis to the isolated rca-investigator agent on complex bugs, gates on confidence(analysis), and at >= 92 % hands off without human confirmation — fast lane via aw-create-plan + aw-executor, standard lane via aw-planner + aw-executor, both under a CEGIS refinement contract. A bug-fix-verifier agent grades the PR before undrafting; for telemetry-sourced bugs an optional Phase 8 polls the originating signal post-deploy. --analyse-only stops at the proposal; --force-holistic skips the fast lane. Triggers on "/fix-bug".
