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.

// #25/#31: a one-step array-LITERAL initialiser for a SLICE
|
|
// local (`let xs: []T = [..]`). Migrated from test/wcc/953_arrlit_slice_run.c
|
|
// (value rows; cs==ww byte-id rides T2). Reject rows, including the
|
|
// stage-asymmetric assignment diagnostic, live under test/wcc/data/.
|
|
//
|
|
// #31 (silent cs!=ww): the borrow wrapped the un-addressable arrlit directly,
|
|
// so .ptr pointed at garbage (xs[1] returned 1, not 20; []u8/[]str SEGV). #25
|
|
// (over-strict): bare-int-width / str elements rejected. The fix re-stamps the
|
|
// arrlit [count]T and materialises a fresh per-borrow stack slot. multi_live is
|
|
// the SOUNDNESS pin: a shared backing slot would alias the two borrows (4+4=8).
