Final hygiene and tooling gates

Base c5177c56e4551c9896a2869c3b23d0c7bac9a6f9; compiler closure 45468f4172e1592f6c9fec7ce56a1af5553aa7ec93b714836b18775138d08352. Source inventory, actual commands, historical epoch/repair bridge.

All required workspace gates pass on this exact source. Warnings are denied; Rust, rustdoc and rustup subcommands are pinned to 1.95.0. Each receipt retains complete output and verifies the owner/Strata inputs before and after execution.

Gate / receipt Actual result
Fmt, workspace Clippy, strict acpu lib/tests Clippy Pass, zero warnings.
Workspace tests 356 passed, 5 existing ignored, including doctests.
Release workspace build Pass.
Release acpu tests 187 passed, 1 existing ignored.
Strict acpu docs Pass.
Acpu matmul Actual AMX 64×64 identity control, maximum error zero.
Aruminium matmul Actual GPU 64×64×64 control, maximum error zero.
Rane matmul Actual ANE execution, all 4096 outputs equal one.
All-target compilation Pass after removing accidental parent-package bench discovery; explicit benchmark-package binaries remain.

The last bridge from 0453b62f… changes documentation only: formula/indexing code spans, a text code fence and truthful Matrix::new behavior. It executes AMX_SET then returns Ok; unsupported hardware may trap rather than return the previously documented error. The earlier strict rustdoc failure remains in ../delivery-v3/docs-acpu.* alongside its passing required runtime gates.

nu audit/2026-10-16-acpu-delivery/verify-delivery.nu <repository> checks historical raw streams/manifests and final source identity without rerunning gates. No measured performance, numeric-overflow repair, version bump or publication is claimed. The remaining Chebyshev coefficient contract/algorithm is a separate numerical unit.
