transcription-whispercpp + transcription-parakeet: bump to registry whisper-cpp 1.8.5#2 / parakeet-cpp 2026-06-04#0

[pratiknarola-t]

Summary

Dependencies-only bump of the whisper and parakeet transcription addons onto the C++ ports just
merged into qvac-registry-vcpkg (PR #183,
registry main = 75bc60c4). This lets CI validate the newly-shipped registry ports end-to-end.

Addon	Port	Pin	Mechanism
transcription-whispercpp	whisper-cpp	1.8.5#1 → 1.8.5#2	overrides.port-version
transcription-parakeet	parakeet-cpp	2026-05-26#2 → 2026-06-04#0	3× platform version>=

ggml-speech 2026-06-04 is pulled transitively by both ports (it is the registry baseline default), so
neither addon needs a direct ggml-speech edit.

What the new ports carry

• whisper-cpp 1.8.5#2 — qvac-ext-lib-whisper.cpp PR testing qvac-lib-dl-filesystem workflow #34: KV-cache CPU-buffer fallback when a single
  K/V tensor exceeds the backend's max single-tensor size (Adreno-740 whisper-cli fix). whisper version
  unchanged (1.8.5); only port-version increments.
• parakeet-cpp 2026-06-04#0 — qvac-ext-lib-whisper.cpp PR updated workflow secrets #38: std::regex parse_adreno_version()
  for robust Adreno-generation detection + backend-select diagnostics.

No baseline change (intentional)

Only the version pins move; the default-registry.baseline in each addon's vcpkg-configuration.json is
untouched. version>= / overrides resolve forward of the pinned baseline — the same way main already
consumes parakeet-cpp 2026-05-26#2 and whisper-cpp 1.8.5#1, neither of which exists at its addon's
pinned baseline commit.

Verification

Local vcpkg install --dry-run resolves clean for both addons on arm64-osx (metal) and x64-linux
(vulkan), pulling the exact registry git-trees:

• whisper-cpp[core,metal|vulkan]@1.8.5#2 → 6111cf47…
• parakeet-cpp[core,metal|vulkan]@2026-06-04#0 → 90f6d24c…
• ggml-speech[core,metal|vulkan]@2026-06-04

CI (on-pr-transcription-whispercpp + on-pr-transcription-parakeet, triggered by the packages/<addon>/**
path filters) is the final arbiter.

Out of scope

tts-ggml addon and the tts-cpp registry port (handled separately); no source/code changes.
