What's Changed

Features

• Post-merge validation — after all tasks complete, the engine now runs make check on the merged integration branch before marking the run as completed. If quality checks fail, the run is marked completed_dirty instead, surfacing cross-spec integration failures that individual worktree sessions miss. (b95b99e4)
• JS/TS coverage detection — coverage regression gate now detects Jest and Vitest projects via package.json, parsing Istanbul-format coverage-final.json output. Vitest requires a coverage provider (@vitest/coverage-v8 or @vitest/coverage-istanbul) to be declared. (c7448c6b)

Bug Fixes

• Review severity definitions — drift-review and pre-review profile templates now include detailed severity criteria with examples, replacing a bare list of level names. API signature mismatches, missing types, and incompatible contracts are explicitly classified as critical. Added "when in doubt, choose the higher severity" tie-breaker. (eeefe370)
• Drift-review blocking made effective — drift-review findings now actually reach the blocking evaluator (queries drift_findings table instead of review_findings). Default threshold changed from None (advisory-only) to 1. Both critical and major findings count toward blocking for pre-review and drift-review. Drift-review now has retry_predecessor=True so blocking triggers a coder retry with findings as context. Audit-review is unchanged per issue #639. (eeefe370)
• Coverage tool false-positive detection — detect_coverage_tool no longer falsely identifies coverage tools based on project markers alone. Python projects require pytest-cov in dependencies, Rust projects require cargo-tarpaulin on PATH. Eliminates silent "Coverage result file not found" log spam on every session dispatch. (69ea1548)
• Spec artifact references updated to v1.2 JSON format — CLAUDE.md template and agent profiles (coder, drift-review, pre-review, verifier) now reference the current spec format (requirements.json, test_spec.json, tasks.json, optional architecture.md) instead of the old v3 markdown format. Added a design information lookup table mapping architectural concerns to their locations across spec artifacts. (c81735d3)
