Vextra v0.8.4 — Fix: Save MIDI button on macOS

The GrooveEngine's Save MIDI button did nothing on Mac builds. Root cause: WKWebView (Tauri's macOS engine) silently blocks programmatic clicks for security. The button fired but nothing happened, no error.

Fix: when running inside Tauri, use the native save dialog + fs writeBinaryFile API instead of the anchor-click trick. Browser fallback is preserved for dev mode. Both paths ship the same .mid bytes produced by patternToMidi().

Enabled dialog.save and fs.writeFile in the Tauri allowlist (+ the matching cargo features: dialog-save, fs-write-file). fs scope is "**" so the user's chosen save location always works — the save dialog itself is user-initiated so no silent file writes can occur.

Vextra v0.8.3 — Hotfix: provider race + first auto-update test

Fixes a race condition where Collections, Favorites, and SavedSearches panels would appear empty after app launch until the user took some action. These providers mount in main.tsx before , so their initial fetch races with the Python backend still warming up the CLAP model. Without retry, the empty state persisted until a later action triggered a refresh.

Each provider now retries the initial fetch up to 30 times with 500ms spacing (~15s window). User-initiated refreshes remain single-shot. Bug predates v0.8.2 — present since v0.6.0 (CollectionsProvider).

Also:

• Settings Updates section now surfaces the actual updater error text when a check fails, making debugging easier
• Rust host falls back to runtime env var for VEXTRA_SESSION_API_KEY so local dev builds can set the key without rebuilding

This release is also the first real test of the Tauri auto-updater: users on v0.8.2 (production install) should now see the update banner and be able to install v0.8.3 directly.

Vextra v0.8.2 — Session Tracking, Auto-Update, Quality-of-Life

Headline features:

• Auto-updater: checks on startup (opt-in), manual check in Settings, signed updates delivered via Cloudflare R2
• Session + key-event analytics: sessions, searches, groove generations, and MIDI exports now surface on the landing admin dashboard, with offline queueing so no event is lost
• Unified version management: single source of truth in src-tauri/tauri.conf.json, propagated to Rust, Python backend, and frontend at runtime — scripts/check-versions.sh guards against drift

Desktop app UX:

• New "Show in folder" action per sample (reveals in Explorer / Finder)
• Results list now has a dedicated Action column; Details and Match columns trimmed so the waveform gets more room
• Duration shows sub-second precision (0:00.4) for short one-shots
• Action icons normalized to a consistent 16×16 stroke style
• Settings: new Updates section with current version + Check for updates
• Splash, sidebar, and About all read the version from Tauri dynamically

Vietnamese search:

• Expanded vi_phrases.json, chips, and idle placeholders with producer slang (nấu beat, bốc, nện, dính, …) — user-edited, pass-through to the existing VI→EN translation pipeline

Infrastructure:

• GitHub Actions builds now sign updater artifacts on Windows + macOS, upload them to R2 at downloads/updater//, and generate downloads/updater/tauri-update.json for the Tauri updater
• Rust host passes VEXTRA_APP_VERSION + VEXTRA_SESSION_API_KEY to the Python subprocess so analytics work in production without extra config

Guardrails respected:

• Search ranking, Groove generator, and audio playback untouched
• Existing downloads/releases/latest.json format preserved for the landing page
• No forced updates; every analytics call is fire-and-forget

Vextra v0.8.1 — Quality, Performance, and Personalization Upgrade

Groove Engine Quality

• Pattern history avoidance: reduces repetitive pattern reuse across regenerate cycles
• Bar 2 evolution: blends from bar 1 instead of jarring full-swap — sounds related, not random
• Fill control: probability reduced to 8%, restricted to kick/snare/perc only
• Hat density limiter: prevents machine-gun hi-hat patterns (max 10 of 16 steps)
• Triangular velocity: more human feel — clusters near center, rarely hits extremes
• Sustain crossfade: bass/lead/loop get smooth 80ms crossfade on retrigger instead of hard cut

Favorites

• Hard cap at 150 with clear feedback when full
• Count display in panel header
• No silent deletion — user manages manually

Search — Filename Matching

• Filename-like query detection: underscores, extensions, word+digits patterns
• Exact filename score: new search component for specific file lookup
• Amplified boosts: +40% for all-keywords-in-filename on filename queries
• Rebalanced weights: semantic 35%, keyword 20%, type 10%, filename 10%, tags 10%

User Tag System (Pro)

• Personal tags: add up to 5 custom tags per sample
• Tag search: search by tag name — tagged samples jump to top of results (3x boost)
• Protected system tags: kick, snare, pad, loop etc. cannot be used as user tags
• Inline UI: tag chips on sample rows, add via +, remove via double-click
• Pro gated: free users see tags read-only, Pro users can create and manage

Onboarding

• Updated guide: 6 steps now including Groove Engine and Personal Tags
• Translated in English, French, and Vietnamese

Library Health

• Missing folder detection: prompts user to re-index when library is moved
