warp: make the build independent of the CPU, rebuild the fonts - #23
Makes the Warp build give the same fonts on every CPU. This replaces #21, which changed only the Bézier terms and left fonts/warp unchanged, so the check "fonts/warp differs from a fresh build" kept failing.
NumPy chooses SIMD or BLAS kernels per CPU for powers, hypot, arctan2, sums, cumulative sums and dot products. The last bits change the curve fit. warp/loom/outline.py now uses products, scalar math calls and sums in a fixed order.
Tests run the fit with AVX-512 on and off (they fail on main and pass here).
The workflow builds a second time without AVX-512 and checks fonts/warp.
Second commit: fonts/warp and proofs/warp rebuilt with the new code (18 files, net +105 bytes).
Proof
pytest warp/tests 90 passed
CPU tests on origin/main 2 failed
CPU tests on this branch 2 passed
build default vs AVX-512 disabled 18/18 files byte-identical
Fontspector 1.9.0 (universal) 894 PASS, 28 WARN, 0 FAIL, 0 ERROR
fidelity maximum 4.016 % (limit 5 %)
Notes
The OCR gate and the MATH proof need Tesseract and LuaLaTeX, which this machine lacks. The hosted warp workflow runs both. Tags (warp-v0.2.0) stay with the founder.
Summary by CodeRabbit
Reliability
Font build results are now consistent across different CPU configurations, with automated checks comparing generated files.
Quality
Updated glyph fidelity and sketch-comparison measurements. Most outline changes are limited to the final coordinate bits, though the Regular Xi outline differs by up to 2 font units.
Documentation
Updated build and validation notes, including local results and pending hosted OCR and MATH checks.
NumPy computes ** with a different AVX-512 code path on some CPUs. The
last-bit differences changed one curve fit (Xi, Regular, up to 2 font
units), so a fresh build on GitHub runners without AVX-512 differed from
the committed fonts and the 'fonts are current' check failed about half
of the runs, with or without a dependency bump. Cubic Bezier terms are now
written as products. The fonts do not change. A test compares the result
with the AVX-512 code paths switched off.

NumPy picks SIMD or BLAS kernels per CPU for powers, hypot, arctan2, sums,
cumulative sums and dot products, and their last bits change the curve fit.
Use products, scalar math calls and sums in a fixed order. Add tests that run
the fit with AVX-512 on and off, and a CI step that builds without AVX-512 and
checks fonts/warp.

18 files change (4996682 to 4996787 bytes). A build with and without AVX-512
gives byte-identical files. Fidelity maximum 4.016 percent; Fontspector 1.9.0:

Selected Warp outline calculations now use scalar math and ordered accumulation instead of NumPy operations. Tests and CI compare results across CPU feature settings. Proof measurements and Warp build notes are updated.
Changes: CPU-independent Warp font builds
Layer / File(s)
Summary
Ordered outline calculations warp/loom/outline.py
Selected geometry and Bézier calculations replace NumPy reductions, vectorized norms, and power operations with scalar math and explicit ordered accumulation.
Cross-CPU tests and CI comparison warp/tests/test_warp.py, .github/workflows/warp.yml
Subprocess tests compare calculation results and generated TTF, OTF, and WOFF2 files across default and AVX-512-disabled settings. The workflow rebuilds fonts with AVX-512 disabled and fails if the result differs from committed fonts.
Updated proof results and build notes proofs/warp/fidelity.json, proofs/warp/sketch-compare.json, warp/CHANGELOG.md, warp/STATUS.md
Selected glyph fidelity and IoU measurements change. The changelog and status report record the CPU-path build update and check results.
machine-made/type#21: Both PRs address CPU-dependent Bézier fitting. This PR also changes other outline calculations and rebuilds the fonts.
Suggested reviewers:claude
Merge Risk: Low · up to bbeeb
The builds remain mergeable with awareness that the CPU-path comparison may not exercise AVX-512 on the available runner. The changelog now clearly identifies the older proofs.

Without AVX-512, both runs can pass without testing AVX-512-dependent behavior. Run the check on an AVX-512-capable runner and use a dispatch-sensitive control to establish that disabling the feature changes the NumPy path.

What
Makes the Warp build give the same fonts on every CPU. This replaces #21, which changed only the Bézier terms and left
fonts/warpunchanged, so the check "fonts/warp differs from a fresh build" kept failing.hypot,arctan2, sums, cumulative sums and dot products. The last bits change the curve fit.warp/loom/outline.pynow uses products, scalarmathcalls and sums in a fixed order.fonts/warp.fonts/warpandproofs/warprebuilt with the new code (18 files, net +105 bytes).Proof
Notes
The OCR gate and the MATH proof need Tesseract and LuaLaTeX, which this machine lacks. The hosted
warpworkflow runs both. Tags (warp-v0.2.0) stay with the founder.Summary by CodeRabbit
