# Nexus OS experience stabilization v1

## Build context

- Repo URL: https://github.com/Ninjajago99/ninja-nexus.git
- Branch: integration/platform-sprint-before-phase1
- Start commit: 656cb77c9bb32aaa7bb9cd6a5d7660d87ef99ad8
- Implementation commit: 24b5df9b8150ebed55b280594d60c97139817329
- Build: 94
- Version: 0.1.0-osxp1
- Latest source checked: https://nexus.ninjakernen.info/downloads/latest.json returned build 93 / 0.1.0-workspace2
- Root latest endpoint: https://nexus.ninjakernen.info/latest.json returned 404, so release tooling should keep using /downloads/latest.json

## Stabilization status

- Installer redesign status: implemented. Setup opens maximized/borderless with larger OS-style layout, two-column system requirements, visible selected install path, clearer install controls, and all 19 install phases shown as a two-column timeline.
- SQLite root cause/fix: fixed first-run install-root fallback. Identity SQLite now resolves to installRoot/data/identity even before the install root exists, creates the data folder before API startup, and Identity API falls back to LocalAppData/NinjaNexus/identity instead of a relative database.
- Log upload/export status: implemented local redacted diagnostic zip export and opt-in send flow. Upload endpoint is PENDING; when missing, Nexus writes a local receipt and support ID instead of uploading.
- Login redesign status: implemented fuller Nexus OS login surface with brand, user initials, welcome label, POC credential marker, loading label, error state, and keyboard focus.
- Enter login status: implemented in LoginView PasswordBox and parent view.
- Update UI status: implemented larger resizable Nexus modal/window without standard titlebar and wrapping button bars.
- Files/Browser containment status: implemented previously and preserved. Files and Browser register with WorkspaceWindowManager and appear as Nexus workspace apps.
- Dock/App Hub status: improved. Dock maps to Nexus Home, Search, App Hub, Files, Browser, Console, Calculator, Settings, Diagnostics, Updates, Store, and Add. App Hub opens with all registered apps.
- Notification center status: improved. Notifications are derived from live system/update/identity/performance/diagnostic events with an empty state.
- Performance status: improved from existing diagnostics baseline. Performance mode, UI/API latency, CPU/RAM, bounded diagnostic queues, and reduced polling behavior remain active.

## Verification

- dotnet build source/nexus-installer/NexusInstaller.csproj -c Release: PASS
- dotnet build source/nexus-identity/NexusIdentity.Api/NexusIdentity.Api.csproj -c Release: PASS
- dotnet build source/nexus-shell/NexusShell/NexusShell.csproj -c Release: PASS
- dotnet test from repo root: BLOCKED because repo root has no project or solution file
- dotnet test source/nexus-installer/NexusInstaller.Tests/NexusInstaller.Tests.csproj -c Release: PASS, 37/37
- dotnet test source/nexus-shell/NexusShell.Tests/NexusShell.Tests.csproj -c Release: PASS, 51/51

## Local POC and upload

- Local POC result: BLOCKED/NOT RUN in this session. A full interactive install/start/login/workspace pass on C:\NinjaNexusPOC is still required.
- Upload status: NOT UPLOADED. The task forbids upload unless local POC passes.
- Artifact URL: not created
- SHA256: not created
- SHA256 match: not applicable
- latest.json status: not updated
- Downloads page status: not updated

## Known blockers

- Full laptop/stationary POC must be run by Jacob or on a real interactive Windows desktop before CDN upload.
- Upload endpoint for diagnostics is not implemented; current behavior is safe local export plus receipt/support ID.
- Root /latest.json returns 404; /downloads/latest.json is the working manifest endpoint.

## Next steps

- Run JACOB_POC_CHECKLIST.md on C:\NinjaNexusPOC.
- If every POC item passes, build and publish build 94, verify artifact URL 200, verify SHA256, update /downloads/latest.json and downloads page, then record the publish receipt.
- If any POC item fails, do not upload; capture diagnostic zip and support ID from Settings > Developer / Diagnostik.
