Multi-dim ORDINAL global array initializer skipped (int a[2][3] = {{1,2,3},{4,5,6}} stays zero)

• Type: bug (cfront global init). Track C.
• Found: 2026-07-08 while landing bug-c-init-brace-elision-nested (test/cinit_elision_nested_b193.c originally probed it; check removed). Pre-existing — pinned stable fails identically, NOT a walker regression.

Symptom

File-scope multi-dimensional ordinal arrays with a brace initializer read 0: int arr2[2][3] = {{1,2,3},{4,5,6}}; arr2[1][2] → 0. Two causes in ParseCGlobalVarDecl:

1. The dims loop only captures dim 1 (arrLen); dims 2+ are token-skipped, so AllocArray reserves dim0 elements, not the product, and SymArrNDims is never set (body indexing arr2[i][j] then relies on... whatever the 1-D fallback does — also verify reads).
2. The nested-brace init fails CBraceIsFlatIntInit → whole initializer balanced-skipped, no PendingInits recorded.

Fix sketch

Capture all dims (mirror the LOCAL decl path, which handles dimSpan[] / SymArrNDims), then route the initializer through the recursive brace-elision walker (CInitWalkArray, landed with bug-c-init-brace-elision-nested) with the sym's dim metadata — the walker already handles nested/elided dims via CInitDimSpanAt; only this ordinal-global entry point is missing.

Gate

int a[2][3] global (nested + flat elided inits) reads correct values on x86-64; make test + self-host; check corpus for users.
