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.

// #251: narrow int/rune array-literal elements to a
|
|
// declared [N]T element type at the let / def / struct-field init sites.
|
|
// Migrated from test/wcc/951_arrlit_elem_narrow_run.c (accept rows; cs==ww
|
|
// byte-id rides T2). The out-of-range and str-elem reject rows stay as runww
|
|
// //ww:error carriers under test/wcc/data/.
|
|
//
|
|
// Pre-#251 cstage REJECTED in-range bare-int/rune lits at local let/def/struct
|
|
// ("[4]i32 not assignable to [4]u8"); wwstage SILENTLY over-accepted out-of-
|
|
// range/str at def + struct-field (a rule-7 miscompile). Element WIDTH is
|
|
// declared-type-driven at cgen, so the byte-id gate confirms the emitted bytes
|
|
// are u8-wide regardless of the literal node type.
