docs: record verified native preview and unfinished PWA parity

Replace current wrapper claims with native architecture/security/build evidence, preserve historical documents, track all thirty pages and explicit release gates, correct brand attribution and provide the twelve-section delivery report without claiming completion. Native signing remains paused and Apple application/device validation outstanding.

-**Development build - not production-ready.** See [validation status](docs/validation.md).
+**Native rebuild in progress — not full PWA parity or production-ready.**
+The previous WebView wrapper did not meet the requested native implementation.
+It is archived under `legacy/` and is not the shipped application surface.
+Read the [feature-by-feature parity tracker](docs/native-parity.md) and
+[current validation](docs/validation.md) before installing a preview.
 No mobile backend, advertisements, telemetry, tracking, subscriptions, or mandatory cloud.
-The configured server supplies the application and retains responsibility for its own
-integrations, version checks, security and privacy.
+The apps render native controls and call the existing server API. The server owns
+authorization, recurrence, synchronization and household business rules.
 
 Use a root-hosted HTTPS instance with a valid certificate, including private servers
 accessible through your VPN. Custom ports are supported. HTTP and subpath deployments
-are intentionally rejected. Enter the server on first launch; use Server settings to
-reconnect or erase local browsing data and switch installations.
