- 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).
- backend/text_layer.py: PyMuPDF text-layer extraction, fuzzy evidence bbox matching, 300-DPI crop rendering, coverage-gap signal - extractor (classic + agent): TEXT LAYER block appended at call sites; grounding guard gains text-layer rescue tier (grounding=text_layer stamp) - verifier: {text_layer} oracle excerpt + evidence-located hi-DPI crops replacing full-page images (fallback preserved, I2 guard intact) - coverage gaps: text-bearing pages with zero extraction -> failed-scope gap findings (agent) / log-only (classic) - config knobs: TEXT_LAYER_ENABLED/MIN_CHARS/MAX_CHARS, VERIFY_TEXT_MAX_CHARS, VERIFY_HI_DPI_CROPS, VERIFY_CROP_DPI, VERIFY_CROP_MARGIN_PTS - tests: 22 new (text_layer unit, grounding/render, runner-level flow) Spec: docs/superpowers/specs/2026-08-12-text-layer-grounding-design.md
