…der) Points parakeet-cpp at the QVAC-22367 fix that bounds offline-transcription memory on long audio: the conformer encoder now slides over the input in overlapping windows instead of running the whole file through a single O(T_enc^2) attention graph (which OOMed on multi-hour audio). ggml-speech floor is unchanged (>= 2026-07-15); this is a source-only bump. WIP until the upstream source PR merges: portfile REPO/REF/HEAD_REF point at Zbig9000/qvac-ext-lib-whisper.cpp @ 963b28db (branch QVAC-22367-parakeet-long-audio); SHA512 is that fork tarball's hash. master has since moved parakeet-cpp/ -> engines/parakeet/ (reorg PR tetherto#95); this pin stays on the pre-reorg ecac5bb7 line so the bugfix does not also adopt the layout migration. On merge, repoint REPO -> tetherto, REF -> the merge commit, HEAD_REF -> master, adjust SOURCE_PATH if it lands on the reorged tree, and recompute SHA512 + the versions git-tree.
