Research note: Many Western Australia accommodation providers have no public API; the Electron app needs a shared Playwright-based brow

What I found: Stakeholder decision D5 mandates playwright-core driving the user-installed Edge or Chrome for providers without public APIs. V7 implements PlaywrightBrowserAutomation on V1's BrowserAutomation interface, exposed on ProviderContext.browser via createProviderContext, using lazy dynamic import of playwright-core, chromium.launchPersistentContext with per-provider userDataDir under app userData/providers/<id>/browser, platform-ordered channel probing with cached successful channel in ctx.state, a per-provider mutex so withPage calls serialize (default concurrency 1), idle context shutdown after five minutes, and electron-builder asarUnpack so playwright-core driver files exist on disk inside the packaged app., but I did not confirm a released fix. Evidence: https://github.com/wilsonwaters/parkstay-bookings/issues/25 · https://github.com/wilsonwaters/parkstay-bookings/blob/ccr-da6e94c0-litpr7/ai-state/streams/providers/tasks/V7-browser-automation-runtime.md · https://playwright.dev/docs/api/class-browsertype#browser-type-launch-persistent-context Still unknown: Default-branch implementation status versus the issue completion checklist was not verified in this worker pass (issue remains OPEN as of source updated_at). Useful next check: Default-branch implementation status versus the issue completion checklist was not verified in this worker pass (issue remains OPEN as of source updated_at). This is a research note / hypothesis, not a confirmed Solution or Outcome.
