What this changes

Fills the 14 cells that #44 left pending (the squash) in bench/README.md: 8 Cortex-M float rows and 6 hexagon rows. They now name the #44 squash d9c1e33 and the push-to-main bench run that confirms them. No baseline, ceiling or code changes.

Why

bench/README.md says the main SHA of a re-record that cannot exist on main before the change does is filled in by a follow-up after the squash. This is that follow-up.

Verification

I read the measured-counts artifacts of run 36367784465 (push to main on d9c1e33, compare mode) against main's bench/baselines.json:

  • Cortex-M float counts: all eight (m4-softfp, m4f, m33, m55-ooura at N = 512 / 2048) match to the instruction.
  • hexagon counts: all six read +22 packets against the dispatch-run baselines, fixed point included. This is the process-environment offset bench/README.md describes (the main ref's runner environment), constant across scenarios and far inside ±3 %. It is recorded in the cells and not re-recorded.

Notes for the reviewer

  • Submodule pin moved: none here. MuTap's bump to d9c1e33 is on MuTap's claude/dsptap-srdif-bump, and its CI is running.

The rows #44 recorded left the main SHA pending until the squash. The
push-to-main bench run on d9c1e33 (run 36367784465, compare mode) confirms
them:
- The eight Cortex-M float rows reproduce to the instruction.
- The six hexagon rows read +22 packets on every scenario, fixed point
  included. That is the process-environment offset bench/README.md
  describes, inside the band, and the baselines are not re-recorded.

The cells now name d9c1e33 and the run. No baseline or ceiling changes.
