transcription-whispercpp: consume ggml-speech 2026-06-02 (Adreno OpenCL selection, QVAC-18993)

[Zbig9000]

Summary

Phase 2 of QVAC-18993 — point the addon at the registry baseline that publishes ggml-speech 2026-06-02 (qvac-registry-vcpkg#178, merged; REF tetherto/qvac-ext-ggml@9bca9b3d = qvac-ext-ggml#18's Adreno-aware Android OpenCL/Vulkan backend selection).

One-line change: default-registry.baseline a9d7e924 → bd344b13a30d2fc5133c4710964a2d3d53691d1c (registry main after #178).

• That baseline already carries whisper-cpp 1.8.5, so the existing whisper-cpp 1.8.5#0 override is kept as-is; whisper-cpp's version>=ggml-speech 2026-05-27 now resolves to 2026-06-02.
• No overlay-ports, no override hacks — the permanent, legitimate change.

Local validation (x64-linux, no overlay, against the real merged registry)

vcpkg resolves ggml-speech[core,vulkan]@2026-06-02 (tetherto@9bca9b3d) ← whisper-cpp@1.8.5 ← spirv-headers@1.4.341.0; build clean; test:cpp 111/111, test:unit 30/30, test:dts clean, test:integration 10/10, accuracy 8/8, chunking 1/1.

The registry port itself was separately vcpkg install-verified (fetch + SHA512 + spirv-headers + patch + build) before #178 merged.

Note

The baseline advance also moves qvac-lint-cpp 1.4.4#3 → 1.4.5 (the only other non-pinned registry dep that moved); harmless (lint config; no C++ change in this PR). qvac-lib-inference-addon-cpp stays 1.2.1.

Relationship to the rest of QVAC-18993

• This propagates the engine-level Adreno policy (testing workflow #18) to the addon.
• The addon-level changes (IGPU backendId reporting fix, Adreno gpu_device guard for the 700+ OpenCL pick, un-quarantined Android GPU test, ggml log forwarding) are in transcription-whispercpp: report IGPU backends (fix Mali silent CPU mislabel) #2343 — complementary, both needed for the full Adreno 700+ behavior.

Test plan

• on-pr transcription-whispercpp CI green (prebuild matrix + cpp/unit/dts + integration)
• device farm: Samsung S25 (Adreno) → OpenCL (no vkCmdBindPipeline crash), Pixel 9 (Mali) → Vulkan

Closing: switching from a default-registry baseline bump to the correct version-pin approach (don't update the baseline; bump the whisper-cpp override to the new port-version). Replaced by the registry consumer-bump PR + a combined addon overlay/version PR for whisper + tts-ggml + parakeet.
