# Party query and historical session compatibility

This adaptor validates current Party query replies for API-owned authentication.
The [API runtime](../authentication/README.md) owns AAI login and browser sessions.

The NextAuth bridge, its configuration and `/auth/party/handoff` and
`/auth/party/revoke` endpoints have been retired. The runtime no longer composes
legacy session-status authority. Retained v1 session structures and wire decoders
remain for historical data compatibility and tests; they do not establish access
through the API-owned session flow. Existing browsers sign in again.

`python3 scripts/api_native_sessions.py` checks session persistence, generation
checks, revocation and canonical realtime disconnection against isolated Valkey.
