…code #3 bounds-check audit — DONE, and the headline is that there is nothing to fix on the hot path: 39 panic_bounds_check sites lib-wide, ZERO reachable from the shipped malloc / free / calloc fast paths (confirmed on the override .so). All 39 are on slow/cold paths (segment alloc/free, visitors, arena, teardown, and 2 on the malloc_generic refill). The safe-Rust allocator pays no bounds-check tax where it matters. The 2 refill checks resisted a min(MAX_NORMAL_BIN) clamp on bin (count unchanged) and sit on a cold path — not worth chasing, recorded so the dead end is not re-explored. #4 update_direct recompute — ASSESSED, premise false. bin_size(bin) for the common bin <= 8 is bin << 3 (a shift), and bin_size(bin-1) runs only for bin > 8. There is no costly recompute on the hot path, and replacing the shift with a table/stored load would reintroduce a panic_bounds_check (bin from bins::bin is unbounded to LLVM) that costs more than it saves. Left as-is. Both are honest negative results with the evidence attached, which is the point of the register: they stop the next person re-attempting a dead end. The Tier-2 win that DID land is #5 (calloc -20.62 Ir/op), committed separately. Co-Authored-By: Claude Fable 5 (1M context) <noreply@anthropic.com>
