Summary

Doc-only follow-up to PRs #85 (W53) and #86 (C-g schema). Refreshes .dev/memo.md, .dev/checklist.md, and .dev/roadmap.md so the next session opens against the new open-work shortlist.

What's left after this evening

  • W47tgo_strops_cached ~15 % slowdown, σ ≈ 18 %. Harness stabilisation (50-run hyperfine alone gives σ_mean / sqrt(2.5); likely needs in-process timing that subtracts module load + WASI startup) precedes the v1.9.1..v1.10.0 bisect.
  • C-g step 5 — pin hyperfine in versions.lock + install-tools.ps1, collect a Windows baseline, then flip the benchmark CI job to a 3-OS matrix.
  • C-g step 3 follow-up — replace e5766ee/x86_64-linux (OrbStack Rosetta) with a row from a native Linux host once one is available.

Test plan

  • CI green (doc-only — should be a fast pass)

W53 and the C-g schema foundation shipped earlier this evening
(PRs #85, #86). Update the three handover docs so the next session
opens against the new open-work shortlist:

- W47 (tgo_strops_cached, ~15 % slowdown, σ ≈ 18 % — needs harness
  stabilisation before bisect).
- C-g step 5: Windows hyperfine pin + native x86_64-linux baseline
  + flip the `benchmark` CI job to a 3-OS matrix.
- C-g step 3 followup: replace the OrbStack Rosetta x86_64-linux
  baseline (committed in `ac4851d`) with one from a native Linux
  host once a runner exists.

memo.md `## Current Task` now describes the W53 + C-g shipment;
the W47 bisect plan is restated as the next priority.
checklist.md W49 entry rewritten to reflect that the schema half
of C-g landed; the matrix flip + native baselines are the
remaining items.
roadmap.md table picks up a `C-g multi-arch bench schema = Done`
row.
