- ENABLE_CODE_REVIEW flag (default off): skips code/ADA/jurisdiction review path in both pipelines; nothing deleted, one env flag to restore. - Per-sheet Drawing Integrity QA wave (agent + classic, default on): dangling refs, on-sheet contradictions, dimension sanity, missing sheet essentials, tag hygiene. New DrawingIntegrityAgent + classic stage. - Broadened conflict critic: intra-sheet + same-discipline contradictions, not just cross-discipline. - Wave 6.5 Brain-directed clarification (bounded hub-and-spoke): Brain names uncertain findings, verify_evidence requests route through the wave-5b verifier; refuted findings suppressed. One planning call + capped verifies, single iteration. Shared _build_verify_scopes across 5b and 6.5. - Config knobs, .env.example, frontend copy, tests (182 passing).
