feat(mobile): manage environment and provider updates

[juliusmarminge]

Mobile users could manage connections but could not update an environment or its providers from their phone.

Adds per-environment maintenance for direct and T3 Connect connections: release checks on the host's current channel, supported server and provider updates, and progress and failure details. Actions require an active connection and operate permission. Only enabled providers appear, with their logos. Environment rows use consistent grouped backgrounds, centered switches, and aligned chevrons without separators. Settings → Maintenance links to the environment controls and remains the home for maintenance preferences.

The preview workflow preserves the Android Google Services file during OTA publication so updates match the native build runtime.

Validation:

• Julius verified on device and approved the final UI. Additional agent device verification and screenshot evidence were explicitly waived.
• Mobile typecheck, targeted lint, and focused maintenance/environment tests passed during implementation.
• iOS and Android preview builds completed; the latest OTAs match their respective runtime fingerprints.
• All required CI jobs passed on the current head; Mobile Native Static Analysis was skipped because native code did not change. No unresolved review threads remain. Macroscope correctness and Effect checks passed; its automatic approvability result is neutral for the scope of this workflow.
• EAS Preview has an upstream reporting failure after successful publication: the Expo action expects build.project, while EAS CLI returns build.app. This remains a CI readiness blocker; it does not prevent installing the published OTAs.

Device previews:

• iOS build · verified iOS OTA
• Android build · verified Android OTA

📝 Walkthrough

Walkthrough

The mobile app adds environment detail and maintenance screens, with navigation from environment lists and maintenance settings. It also adds helpers for update eligibility and release lookup. The preview workflow exports a Google services file variable when present.

Changes

Mobile environment maintenance

Layer / File(s)	Summary
Maintenance eligibility and release lookup apps/mobile/src/features/settings/environment-maintenance.ts, apps/mobile/src/features/settings/environment-maintenance.test.ts	Helpers determine whether a connected environment or provider can be updated and find a newer release on the current channel. Tests cover eligibility and release lookup outcomes.
Environment detail and maintenance actions apps/mobile/src/features/settings/SettingsEnvironmentDetailRouteScreen.tsx, docs/user/updating.md	The detail screen shows connection, permission, server, and provider status. It checks for server releases and runs eligible server or provider updates. The guide describes these controls.
Environment detail navigation and row presentation apps/mobile/src/Stack.tsx, apps/mobile/src/features/settings/SettingsEnvironmentsRouteScreen.tsx, apps/mobile/src/features/settings/SettingsServerControlsRouteScreen.tsx, apps/mobile/src/features/connection/*, apps/mobile/src/features/settings/components/SettingsSwitchRow.tsx	The settings stack registers the detail route. Local and cloud environment rows and maintenance settings navigate to the selected environment. Environment list rows and containers receive presentation and accessibility updates.

Preview workflow environment export

Layer / File(s)	Summary
Export the preview environment variable .github/workflows/mobile-eas-preview.yml	The workflow parses the pulled environment file and exports T3CODE_ANDROID_GOOGLE_SERVICES_FILE to later steps when the variable is present.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 4dfd1

The new environment maintenance screens and navigation work as intended. The one remaining issue is small: environments that are available but not yet connected show an arrow that suggests they can be opened, but tapping them does nothing. This is a quick fix and does not block use.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a substantial mobile environment-management workflow that can remotely restart servers and update provider installations, with broad new navigation and runtime behavior. An unresolved functional issue also leaves chevrons on cloud environments that cannot open details.

[juliusmarminge]

Review follow-up: both inline findings have been answered and resolved. Release selection matches the existing CLI policy, and dimmed chevrons on unavailable rows are an explicit maintainer request verified on device. The Macroscope approvability summary predates resolution of the chevron thread; its remaining broad-scope eligibility judgment is not a code defect. The generic docstring-coverage suggestion does not warrant boilerplate comments under this repository’s documentation guidance. All required CI jobs passed. EAS Preview still fails in the upstream action’s report generator after successful publication, so the PR is open for review but not fully green. Additional device checks and screenshot evidence were waived by the maintainer after on-device verification.
