Identity: rename the application identity to com.companionglp.glpcompanion on every platform (Android applicationId/namespace + MainActivity package, iOS/macOS bundle IDs incl. RunnerTests, Windows CompanyName/copyright, web manifest id, Supabase OAuth redirect scheme).
Deep links: register the custom scheme com.companionglp.glpcompanion:// in iOS/macOS Info.plist (CFBundleURLTypes), the Android VIEW/BROWSABLE intent-filter, and Windows per-user HKCU protocol registration. Server-side steps (Supabase uri_allow-list, Entra optional email claim) are recorded in BUILD_STATE.md.
Windows runner: single-instance mutex (Local\GLPCompanionSingleInstance) so login callbacks are delivered deterministically; SendAppLinkToInstance forwarding with foreground/taskbar-flash fallback so protocol activation can never look like a hang; protocol diagnostics appended to TEMP glpcompanion-protocol.log.
macOS: add the missing com.apple.security.network.client entitlement so the sandboxed runner can reach Supabase at all.
Auth UX: surface deferred OAuth/magic-link handshake failures as snackbars on the login screen; make isAuthenticatedProvider reactive (watches authStateProvider) with a microtask-deferred router refresh so live sign-in and sign-out redirect correctly; add a debug package:logging listener so supabase_flutter diagnostics are visible under flutter run.
Field-verified on Windows: Google, Microsoft (Entra ID), and email magic-link sign-in round trips plus sign-out redirect to /login.
- Master asset assets/icon/app_icon.jpg (2048x2048) plus idempotent
assets/icon/generate_icons.py (Python/Pillow, Lanczos resampling) that
regenerates every platform icon size; preview_contact_sheet.png
documents the rendered variants.
- Web: favicon.png (32px) and icons/Icon-192/512.png gain a feathered
circular alpha mask (removes the master's white JPEG corners); new
Icon-maskable-192/512.png place the logo in the 80% safe circle over
brand sage #D4E4C7; manifest.json and index.html swapped from Flutter
placeholders to "GLP-1 Companion" naming with theme #375A53 /
background #D4E4C7.
- Android: legacy mipmap-*/ic_launcher.png (48-192px) with transparent
corners, plus first-ever adaptive icons: mipmap-anydpi-v26
ic_launcher{,_round}.xml, a sage vector background, and 5-density
foreground PNGs confining the logo to the 66/108dp safe circle.
- iOS: all 15 AppIcon.appiconset PNGs (20px-1024px) rendered opaque RGB
with no alpha channel per App Store validation.
- macOS: app_icon_{16..1024}.png with transparent corners.
- Windows: multi-resolution app_icon.ico (16/24/32/48/64/128/256px).
- Docs: BUILD_STATE.md Post-Phase-7 icon branding entry.
Verified: PIL assertions on dimensions, color mode, alpha, and ICO
frames; adaptive-icon XML well-formedness; flutter build web
--no-tree-shake-icons and flutter build apk --debug package the new
assets.
