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.
test/byteid/wwi_test.ww carries every assertion of both carriers: the
M2 producer gate (ascii/strings/getopt driver-combined positives with
byte-id + wwdump -a re-parse, the synth decl-kind/type-node sweep with
the #47 @symbol round-trip, the #48 types export-def gate, and the
negative private-nominal leak with both-stage identical reject
diagnostics), plus the #11 wwileaf decl-less-leaf rows (package-line
leaf, cross-stage .wwi byte-id, importer resolution + .s byte-id).
Byteid carriers 10 -> 8; docs counts move; the byteid ww target gains
the wwdump prereq its re-parse legs invoke.
