Trainlog v0.1.2 extends the local-first desktop and Android workflow while
keeping each SQLite database private to its device.
## Web and Programs
- The loopback-only Web application now provides the Dashboard, Sessions, and
Programs administration surfaces.
- The top-level Programmes calendar presents active Program sessions by real
planned date and uses the Core-provided `todo`, `prepared`, `in_progress`,
`completed`, and `deleted` execution states.
- Manual and Program-derived preparations preserve their stable provenance,
ordered exercises, targets, loads, and revision history.
## Android execution and history
- A prepared Program session can be delivered to Android, started explicitly,
resumed from the durable local draft, and completed without inventing a
performed session at delivery time.
- Completed Android sessions return to desktop History exactly once and advance
their Program calendar entry through the stable execution-session identity.
- Causal deletion, withdrawals, retained generations, and replay protection
prevent removed data from being resurrected.
## Synchronization
- The complete generation protocol transports versioned artifacts, manifests,
correlated acknowledgements, and causal operations through one idempotent
business engine.
- USB/MTP remains the preferred local transport. A separately configured
private Google Drive namespace is maintained as a mirror and serves as a
fallback when USB is unavailable.
- Android can process desktop USB requests through an explicitly enabled
foreground service, and bounded WorkManager checks handle the private Drive
folder selected by the user.
- After initial background activation, the Web Synchronize action can complete
a USB conversation without opening Android's SyncScreen for each run.
- Trainlog remains local-first: desktop and Android SQLite databases stay local
and are never synchronized through USB or Google Drive.
## Assets
- `trainlog-android-v0.1.2.apk`: signed Android APK.
- `trainlog-tui-linux-x86_64-v0.1.2`: Linux x86-64 runtime bundle containing
the TUI, local Web adapter, synchronization helpers, and required catalogs.
- `SHA256SUMS`: SHA-256 checksums for both artifacts.
