Every section banner dies (103 -> 0) across test/lang, the observer suites, the C carriers, and the five comment-heavy corpus fixtures; banner provenance (#N cites, carrier numbers, repair-cluster labels) folded into headers or adjacent WHY comments. Narration deleted; row provenance, ref cites, divergence pins, and layout contracts kept (fwd-ref decl-order guards and bootstrap-gate corpus rationale restored where the sweep over-cut). Comment-only proven: all 3742 wwbuild workdir .s byte-identical before/after; test-commit and test-byteid (161 lang + 1399 data, 0 pinned-divergent) green.
