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.
Proof-of-path for the test-arch reframe: pure-behavior rows become
in-language @test row-tables run by `ww test`, reserving C drivers for
the two irreducible jobs (byte-id + bootstrap). 110_uniesc's 6 value
rows become [N]struct row-tables in a new test/lang/ tree; the trailing
.wwi round-trip stays in C as external-observer residue. Additive — the
C rows are kept; de-dup and make-rewiring land at fold 6 (task #12).
Green on both stages.
