- Save every completed generation to SQLite (generation_store.py) with
WAV and waveform peaks written to data/generations/<id>/
- Deferred DB write until success — cancelled/errored generations never
touch the DB and never appear in the library
- Fixed cancel+regenerate IndexError: _reset_scheduler_caches() now
directly zeros scheduler._step_index and running state in addition to
clearing VibePod cache dicts; same explicit resets added in the fresh
path of prepare_noise_scheduler as belt-and-suspenders
- Added /library page with GenerationCard, WaveformPreview, waveform
fetch, play/pause, download, delete, pagination, empty + error states
- Added generation API routes (list, single, audio stream, waveform,
delete) proxying to Python server
- Added Library nav link to Header with active state
- Persist script/speaker/CFG to localStorage so generate page state
survives navigation
- Updated build plan: Phase 0+1 ticked off, better-sqlite3 moved to
Phase 2, architectural note on Python owning all persistence
* Improve CPU Inference Stability: Implement Adaptive Buffering and Chunk Accumulation
This change addresses audio stuttering issues when running on CPU-only hardware by:
- Implementing server-side audio chunk accumulation to reduce SSE overhead.
- Introducing device-aware default configurations for buffering and inference steps.
- Exposing key performance parameters as environment variables.
- Enabling the frontend to adaptively adjust its buffering thresholds based on the server's configuration.
Changes:
- Modified `server/vibevoice_server.py` to support accumulation and provide config via `/health`.
- Updated `web/hooks/useStreamingGeneration.ts` to accept configurable buffering parameters.
- Updated `web/app/page.tsx` to fetch and apply server-side configuration.
Verified on CPU mode in the development environment.

* Improve CPU Inference Stability: Adaptive Buffering UI & Logic
This change enhances the initial CPU stability fix by:
- Exposing adaptive buffering settings (Pre-buffer, Re-buffer Threshold, Resume Threshold) in a new "Advanced Buffering" UI section.
- Managing buffering settings in the application state to allow for manual overrides.
- Implementing robust re-initialization of buffering and inference defaults whenever the server's device (CPU/CUDA) changes.
- Including the active device in the server's config object for reliable client-side detection.
Verified with frontend screenshots and full build. Responds to PR feedback regarding actioning the adaptive logic.

* Refine adaptive buffering: env helpers, threshold validation, a11y fixes
- Extract _env_int/_env_float helpers in server to validate env-var config
with graceful fallback instead of bare int/float casts
- Fix inference_steps falsy-check (0 is valid) to use explicit None guard
- Enforce rebufferThresholdSecs < resumeThresholdSecs in both the hook
(with console.warn + clamp) and the GenerationControls UI (sliders block
invalid states by auto-bumping or ignoring the drag)
- Add type="button", aria-expanded, aria-controls, htmlFor, and input id
attributes to GenerationControls for accessibility
- Add .vscode/settings.json to .gitignore; sort package.json scripts

Extract the duplicated offline response payload and common headers into
constants to improve maintainability and readability.
- Define OFFLINE_RESPONSE for { status: "offline" }
- Define COMMON_OPTIONS for { headers: { "Cache-Control": "no-store" } }
- Use these constants across all response paths in the route.
