-      'v0.12.0 — WhisperX as a one-click dashboard install. The Audio / Speech tab now shows an "Add WhisperX" banner the first time you open it (when WhisperX isn\'t installed). Clicking it ships the build context to Spark 2 over SSH, runs docker build (~10–15 min first time), runs docker run with a 40 GB memory cap (so a long-audio pathological case gets OOM-killed cleanly instead of swap-thrashing the whole Spark — what bit us with Sortformer on a 90-min file), and polls /health until both Whisper + pyannote 3.1 report loaded. Progress streams live in a build-log dialog with phase + elapsed timer. Once installed, WhisperX auto-appears as a managed service alongside Parakeet and Magpie (Start/Restart/Stop, deep-check, auto-restart on wedge — same lifecycle as the others). The /api/audio/transcribe-with-speakers endpoint now prefers WhisperX when it\'s healthy and falls back to the legacy Parakeet + Sortformer path otherwise — clean cutover, no client-side changes, easy rollback. New endpoints: GET /api/whisperx/status, POST /api/whisperx/install, GET /api/whisperx/install/{job_id}, GET /api/whisperx/install/{job_id}/stream (SSE).',
+      'v0.12.0:1 — hotfix: 0.12.0:0\'s install action used shlex.quote() on the remote build path, which wraps `~/whisperx-build/...` in single quotes — the remote shell then doesn\'t expand the tilde and treats it as a literal directory named `~`. Result: "bash: line 1: ~/whisperx-build/Dockerfile: No such file or directory" on the very first file copy. Same bug pattern we hit before with $HOME in the disk probe. Rewrote to embed $HOME in double-quoted remote shell strings; hardcoded file names (Dockerfile, requirements.txt, README.md, app/main.py) embed unquoted inside that scope. All other 0.12.0 behavior is unchanged.',
