Allocation reads as intent, not malloc: mem_alloc(64) -> bytes(64) (64 bytes -> a byte buffer) mem_alloc(w * h * 4) -> words(w * h) (w*h 32-bit words) bytes(n) mallocs n bytes and returns a plain pointer (byte-indexed); words(n) mallocs n*4 bytes and returns a `words` pointer (int-indexed). Since words(X) and mem_alloc(X*4) allocate the identical number of bytes, the migration cannot change any allocation size — the `* 4` factor just moves from the argument into the allocator name, pairing naturally with the Phase-7j `words` retyping (`var fb: words = words(w * h)`). Migrated 102 sites (mem_alloc(E*4) -> words(E), else bytes(E)); deleted the mem_alloc intrinsic. mem_realloc/free/copy/set stay as the low-level reallocation/free family. Reseeded (22565 lines); C-free fixpoint holds; goldens byte-identical; 18/18; vocab + doc-fences clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
