Extend the OG_DEMO demo driver into a scenario-driven mock so the whole sensor lifecycle and alert surface can be exercised in the iOS simulator without real BLE. - Add MockScenarioCatalog (mock_scenarios.dart): pure, clock-injectable mapping from MockScenario -> CgmSessionSnapshot for warmup, activeNormal, activeHigh, activeLow, rapidRise, rapidFall, expiringSoon, expired, signalLoss, disconnected, multiSensorHistory, and error. - Make DemoCgmDriver/DemoCgmSession scenario-driven with a live applyScenario() switch; default stays activeNormal so existing demo behavior is unchanged. - Select the initial scenario via --dart-define=OG_SCENARIO=<name> and switch at runtime from a new "Mock scenario" picker in the Developer settings tab. Both paths gated behind OG_DEMO; production untouched. - Tests: scenario->snapshot mapping, live scenario switching, and a widget test driving the Developer-tab picker end to end.

Staged mock sensor harness
A switchable scenario system so the fleet (and the founder) can test every sensor scenario in the iOS simulator without real BLE. This is the testing backbone for the sensor-lifecycle / alert features.
What's in it
Extends the existing
DemoCgmDriverinto a scenario-driven mock. A new pure, clock-injectableMockScenarioCatalogmaps eachMockScenarioto a fully-formedCgmSessionSnapshotso the dashboard renders that exact state.Scenarios:
warmup,activeNormal,activeHigh(sustained high — trips high alert),activeLow(sustained low — trips low alert),rapidRise,rapidFall,expiringSoon(hours left on the 15-day life),expired(offboarding / session stopped),signalLoss,disconnected,multiSensorHistory(previous + current sensor),error.How to switch scenarios
flutter run --dart-define=OG_DEMO=true --dart-define=OG_SCENARIO=activeHighBoth paths are gated behind
OG_DEMO; production builds are untouched (default scenario isactiveNormal, preserving the original demo behavior).Verification (iPhone 15 simulator)
flutter analyzeclean (only the one pre-existinglive_activity_payload.dartinfo from the base branch).flutter test— all 36 tests pass, including newmock_scenarios_test.dart(scenario→snapshot mapping + live switching) and a widget test driving the Developer-tab picker end to end.warmup—/tmp/og-mock-warmup.png("40 min — Warming up", empty history)activeHigh—/tmp/og-mock-activeHigh.png(234 mg/dL, history riding the high band)expired—/tmp/og-mock-expired.png("Sensor expired", readings frozen 2h ago)🤖 Generated with Claude Code
