Summary

• add the complete mysql-leading-wildcard synthetic Prometheus + Loki + MySQL case
• enforce a 13/9 evidence tradeoff, counterevidence, dependency-aware timeline and read-only canonical path
• keep the public scenario separate from the repository-only answer draft and future scoring contract
• add invariant, privacy and side-effect tests plus P2-002 documentation

Safety boundaries

• all fixtures are synthetic
• MySQL evidence is limited to SELECT and EXPLAIN
• trace correlation stays in log bodies rather than labels
• production writes, restarts and deletion require approval and are never executed

Validation

• ASTRO_TELEMETRY_DISABLED=1 npm run validate
• 13 test files / 159 tests passed
• static build and 29 output checks passed

Closes P2-002. P2-003 remains the next task and will consume only scenario.json.
