Follow the shared source-of-truth, permission and evidence rules in `../../references/workflow-contract.md`. Read `../../references/repository-discovery.md` for detailed method when necessary.\n\n## Procedure\n1. Read scoped repository rules, manifest and just enough entrypoints/source/tests for the user question.\n2. Trace one representative path across handlers/services/persistence or client/integration boundaries; identify public contracts and invariants.\n3. Mark facts by observed file paths and known versions. Separate uncertain assumptions from direct observations.\n4. Summarize the structure and likely change points; do not refactor unless asked.\nDeliver a focused codebase map, flow diagram in text when useful, contract inventory and questions only for true blockers.\n\n## Handoff rule\nState actual artifacts or grounded code findings and validation status. Never invent file paths, executed tests, tool access, or completed subagent work. Keep output proportionate to the user request.\n"
