Format × platform: named host runs¶
Every run below is dated 5 November 2026. Each evidence link names its dated WORK_STATUS entry.
| Format | macOS arm64 | Windows 11 x64 VM | Arch Linux x86_64 |
|---|---|---|---|
| CLAP | REAPER 7.82/macOS-arm64 on macOS 27.0.1: fixed/synced renders, edits/readback and project recall (run, merged-harness reruns) | REAPER 7.82/x64, WaveOut: same harness, three passing runs (run) | REAPER 7.82/linux-x86_64, JACK: same harness (run, rerun) |
| VST3 | Ableton Live 12 Suite on macOS 27 arm64 (point version not recorded): manual fixed/synced exports match the strict sample checker (run) | REAPER 7.82/x64, WaveOut: edits/readback, project recall and fixed/synced renders, three passing runs (run) | REAPER 7.82/linux-x86_64, JACK: same harness, three passing runs (run) |
| LV2 | REAPER 7.82/macOS-arm64 on macOS 27.0.1: edits/readback, project recall and fixed/synced renders (run) | REAPER 7.82/x64, WaveOut: same harness, three passing runs (run) | REAPER 7.82/linux-x86_64, JACK: same harness (run, rerun) |
| AUv2 | Logic Pro on macOS 27 arm64 (Logic version not recorded): manual fixed/synced bounces, typed values, editor reopening and saved-project recall (run); REAPER 7.82/macOS-arm64 on macOS 27.0.1: edits/readback, project recall and fixed/synced renders after the transport-residue fix (run) | Not applicable | Not applicable |
| AAX | Pro Tools 26.4, macOS arm64 (OS version not recorded in this entry): manual fixed/synced bounces, mouse editor use; keyboard typing failed in this run; after the decision 0286 fixes characters work and click-away commits, while Return/Escape stay Pro Tools shortcuts (run) | Provisional, owner decision on 5 November 2026: Windows bundle built and adapter-checked; not run in Pro Tools for Windows (build/checks, decision recorded in release plan) | Not applicable |
The REAPER harness checks 48 kHz offline master-mix renders, 63 host checks per run, two project recalls and exact echo positions/mix/silence. It does not exercise live playback, custom editors or automation. The VM's WaveOut and Linux JACK settings identify the environment; they do not qualify a device. The macOS merged-harness CLAP rerun also records one initial startup timeout.
The manual Live exports match the strict checker after unwarping the clip and typing exact values; editor lifecycle and session recall were not recorded. Logic's bounces include the metronome, so checks used exact delay sample positions and amplitudes rather than a whole-file checker pass. In Pro Tools, echo timing and sync were measured, but the strict checker fails amplitudes because the dragged/reset values differ from exact targets; the fixed default also has a small one-sample split from normalized parameter precision. The release plan's previous blanket “sample-exactly” wording must not be read as a strict checker pass for these manual runs.
