Getting arbitrary key injection working on Android without root required three attempts: AccessibilityService (too limited for modifier keys and non-text apps), a custom IME (same ceiling), and a hand-rolled ADB wireless debugging client (pairing worked, but Samsung Android 16 rejected the keys for an undiagnosable reason). Shizuku solved it cleanly — shell-uid Binder IPC via the same wireless debugging infrastructure. The full action vocabulary is dispatched through a JNI bridge that bypasses the WebView entirely, so injection keeps working when the app is backgrounded. APK coming soon.

Shipped v0.1.2 — the first release where the full pipeline works end-to-end: build, sign, publish, auto-update. Getting there required hunting down three separate bugs: a missing config key that silently suppressed the auto-updater manifest, a Windows API breaking change in the focus monitor, and a tray icon crash that took down the app before the first window opened.

Shipped OS desktop notifications for device and layer events (Epic 16). Audited the key dispatch path and found six categories of silent failure — arrow keys, all F-keys, punctuation, media, and system keys were all declared valid but never fired. Rewrote name_to_key, added media_stop/pause/brightness/eject/mic_mute, and upgraded the key picker to a grouped select.

Replaced alphabetical startup profile selection with a preferences.json that remembers the last activated profile. Fixed a bug where explicit deactivation was indistinguishable from first-launch state, causing a profile to always be selected on restart. Added device-aware suggestion banners.

Improved scan UX with seen/paired/cached device states and stale-RSSI fixes. Added connected device name persistence. Seeded a starter profile on first launch. Renamed reference docs. Implemented live device role reassignment without disconnecting.

Scaffolded the mapxr project site with Svelte 5, Tailwind CSS v4, and DaisyUI v5. Implemented landing page, docs scaffold, and devlog view with full hash-based routing.

Fixed double-tap inversion bug caused by TAP Strap hardware bounce. Added 50ms debounce window to ComboEngine. Also added GitHub Actions workflow for Windows builds and a user-facing README.

Implemented the hold_modifier action with Toggle, Count, and Timeout modes. Added HoldModifierMode enum, full validation, and 15+ tests. Spec-approved before implementation.

Updated the BLE scanner to filter advertisements by TAP service UUID so only genuine TAP Strap devices appear in the device list.

Implemented the full ComboEngine with single-tap, double-tap, and cross-device combo detection. Timing is controlled via tokio::time for deterministic tests.

Added profile validation rules (duplicate triggers, missing actions, hold_modifier constraints). Implemented LayerStack with push/pop/activate semantics.

Defined TapCode, Trigger, Action, Profile, and Layer types. Full serde round-trip tests. Profile deserialization from .json fixture files.
