A real mobile foundation, not a webview

Offline is designed into the write path

A SQLDelight queue stores durable requests, replays them through a shared authenticated client, and uses idempotency keys so retrying a capture does not duplicate it. Offline packs are integrity-checked immutable snapshots with localized text resolution.

Native capabilities sit behind small seams

Barcode scanning, speech, on-device models, secure credential storage, location, evidence bytes, and auth launchers remain platform implementations of shared contracts.

• Android: Compose, ML Kit, speech, Gemini Nano, Keystore, Custom Tabs.
• iOS: SwiftUI, VisionKit, Speech, Foundation Models, Keychain, ASWebAuthenticationSession.
• Shared: StateFlow presenters, session bootstrap, packs, evidence, networking, and queue policy.

The server contract is part of the framework

smrt-users provides reusable /api/mobile handlers for brokered PKCE login, session bootstrap, device registration, and multipart upload. App-specific bootstrap data belongs in an explicit extras object.
