# HANDOFF — Session State

## Branch
`main` — clean, uncommitted TASK 10 changes

## What shipped this session

1. **TASK 10 — Polar billing + Velopack auto-updates (steps 1–7)** — full license key activation flow:
   - **Velopack** — NuGet `Velopack` 1.2.0 added, bootstrap in `App.xaml.cs` (`VelopackApp.Build().Run()` in try/catch). Self-hosted update URL TBD (DO droplet). The bootstrap is a no-op until the update URL is configured.
   - **PolarLicenseService** — `Services/PolarLicenseService.cs`: `POST .../validate` with `key` + `organization_id`. Returns `status` (`granted`/`revoked`/`expired`) + `expires_at`. No auth. Network errors surfaced gracefully.
   - **License key entry UI** — About overlay gains a third panel (same pattern as Licenses): text input + "Activate" button + status message. "Enter License Key" button added to the hub (alongside "Unlock Premium" which opens the Polar checkout URL). `IsHubVisible` computed property hides the hub when either sub-panel is open.
   - **Entitlement persistence** — `LayoutStore` gains `LoadLicenseKey`/`SaveLicenseKey`, `LoadLicenseValidatedAt`/`SaveLicenseValidatedAt`, `LoadIsPremium`/`SaveIsPremium` via the Settings key/value table (no schema version bump needed). 14-day offline grace period: cached premium state trusted while online re-validation runs in the background.
   - **BrandFlash toggle** — `IsPremium` property setter flips `BrandFlashEnabled = !value`. On startup, `ValidateLicenseAtStartupAsync` loads cached state → attempts online re-validation → overrides cache on success → lapses on failure/expiry. Premium removes the watermark; free tier keeps it.
   - **PremiumUrl wired** — set to `https://buy.polar.sh/polar_cl_ueMy8AyAClO0o0yo19IroZwKTbD587gzUsjEW3bFapw`. `IsPremiumAvailable` now true. About overlay "Unlock Premium" button lights up. Tooltip updated.
   - **About text updated** — "one-time unlock" → "subscription".

2. **Polar MCP auth** — authenticated via `opencode mcp auth Polar`. Polar MCP connected.

## Files changed

- `Services/LayoutStore.cs` — new: `Load/SaveLicenseKey`, `Load/SaveLicenseValidatedAt`, `Load/SaveIsPremium`
- `ViewModels/MainViewModel.cs` — `IsPremium` (was `static false`, now instance + DB-backed), `PremiumUrl` set, `BrandFlashEnabled` wired to `!IsPremium`, license fields/commands/validation methods, `IsHubVisible`, startup validation
- `MainWindow.xaml` — license entry panel, "Enter License Key" button, hub visibility binding, About text
- `MainWindow.xaml.cs` — `BackToAbout_Click` closes both sub-panels
