Release v0.126.0#692
Conversation
Covers the twenty PRs since v0.120.1 (#655, #667-#669, #673-#688), ABI minors 0.121.0 through 0.126.0, and the scene format minor 19 -> 20. The device gate block is a placeholder until the iPad run is recorded. Carries the four manual hardware gates forward as waivers at 4401b35: the only kernel-relevant change since 59e42cc is #680's per-brick cull band in include/clay/eval/bake_volume.h, which changes what a brick compiles, not kernel arithmetic, and the parity corpus is unchanged.
The multires stroke-session consumer now takes a clay_multires_delta, so its known limit is gone; the at-a-glance table, the session section, Upgrading and the RELEASE.md entry say so.
The gate passed at 7049e19 against the iOS 27.0.1 baseline #690 recorded from v0.120.1's engine, so REGRESSION compares v0.120.1 to v0.126.0 on the same OS: iPad15,5, 75 cases, seven cold sessions with 1800 s cooldowns, nominal throughout, canary steady at x1.18, median ratio 0.996, none above both the 1.4 tolerance and the 0.125 ms floor, largest rise 1.04x. The first run at 7406eb1, before #691, failed on mask_extrude (x4.97, 26992 ms at 1000 stamps against an 8154 ms budget) and mask_extract (x6.26); with #691 they read 1.01x and 1.04x. The stroke cases read 0.81-0.89x, named as a candidate for #688 and not a claim. The run needed the iPad's Wi-Fi off and an air conditioner; the notes say why.

claycore v0.126.0
The release branch for v0.126.0: twenty-two PRs since v0.120.1 (#655, #667–#669, #673–#689, #691), ABI 0.121.0 through 0.126.0, scene and

With #691 they read 1.01x and 1.04x (mask_extrude52.4 / 377.9 / 3680 ms at 10 / 100 / 1000 stamps against 51.6 / 374.5 / 5297).

The gate skill (merged in #690) records that and the preflights that catch it.
Release checklist
python3 tools/release_check.pyatfe97a210: every row passes — version 0.126.0 in cmake, ABI and wheel; configure, build, tests; parity (cpu, 48 cases, 1,411,877 assertions); layering; dialect; licenses; task-symbols; bindings (773 capabilities); kernels; abi; openspec; device (75 cases on iPad15,5 at 7049e19); the four hardware gates carried as waivers at4401b354(the only kernel-relevant change since59e42ccfisinclude/clay/eval/bake_volume.h, #680, no kernel arithmetic); benchmarks; wheel quickstart. "all gates passed — safe to tag".After merge
