From 8a63e90363f31423038622fe8347f2ed93bae73c Mon Sep 17 00:00:00 2001 From: Luca Barbato Date: Thu, 1 Oct 2026 23:17:32 +0200 Subject: [PATCH 1/5] spec(record): define the five-gate preflight repair, and file its issue ISSUE-LOCAL-01M3WMKTBEDAHF226YSATSR7BF: five record/doc gates are red on origin/main. The spec names each checker's contract and the record each repair restores; the commit order that follows proves the spec landed before the implementation it governs.

It takes any device name `vt` knows (`vt::DeviceTypeName` — `cpu`, `cuda`, `metal`, `vulkan`, `xpu`, `rocm`, `tenstorrent`) and resolves it through `vt::DeviceTypeFromName`, so a provider registered for a new backend becomes reachable here with no edit. A name `vt` does not know, or one whose device has no registered `vt::Conv1d` / `vt::ConvTranspose1d` provider in this build, is REFUSED by name — never silently downgraded to the host, because a silent fallback means an operator who asked for a device never learns they did not get one. The transposed convolution is 88.5 % of MiniMax-Music3's acoustic-half profile and on scalar host loops a 45 s clip is a multi-hour decode, so this is the knob that decides whether that stage runs on the GPU. The two providers are BYTE-IDENTICAL — one f64 accumulator per output element walked in the same order, the host pinned `-ffp-contract=off` and the device kernel pinned with `__dmul_rn`/`__dadd_rn` — and `tests/vt/test_ops_conv1d_general.cpp` gates that with `memcmp`, not a tolerance. It still defaults to `cpu`: flipping four shipped audio models onto a device arm is not a default the row that ADDED the arm is entitled to set, and the flip is owed to the wiring row named in [.agents/specs/minimax-music3.md](../.agents/specs/minimax-music3.md) §11.4.

The 2026-09-26 sync 4f11dfc10 advanced the pin to a7c23ac96d / 0.3.0.dev267 but left the oracle record and five prose surfaces at e126687a9a / 0.28.1rc1.dev132. Every span now restates the current pin, and the surrounding "since 2026-09-03" claims are re-dated to the advance that actually produced it. NOW.md also gives back one line so the live digest is not exactly at its cap.
