# Mobile feature delivery

## Inputs

Existing stack/version, target OS range, device access, offline requirements and API contract.

## Procedure

1. Use the existing framework and define platform-specific exceptions. Model loading, failed requests, permission denial and offline edits explicitly.
2. Implement the shared behavior behind tested adapters. Bound retries and define duplicate/conflict handling before queueing writes for reconnection.
3. Run the feature on each available target, checking background/foreground transitions, network loss, keyboard, accessibility and persistent state after restart.

## Worked example

An offline note is edited twice and synced after reconnecting. Verify one intended final record, a visible conflict policy and no duplicated submission.

## Verification and handoff

Report the actual files or configuration changed, checks performed, observed results and any untested environment. Keep the original inputs and evidence sufficient to reproduce the conclusion.

## Limitations

A cross-platform build does not prove feature parity on untested devices. Store submission and signing remain separate authorized actions.
