- Track terminal response IDs per connection to idempotently handle late interrupts targeting completed turns
- Prevent late interrupts from contaminating subsequent requests or returning false errors on idle retained connections
- Add thread-safe diagnostic logging of sanitized interrupt outcomes in the Responses websocket handler
Closes: #6483
- Track terminal connection errors on websocket session when upstream read loops fail or receive unexpected binary payloads
- Return recorded terminal errors immediately during session activation to prevent callers from blocking indefinitely after upstream disconnects
- Reset terminal error state when configuring new connections
Closes: #6354
- Avoid acquiring write mutex in ping handlers so keepalive pongs reply immediately during active writes.
- Stream payload messages larger than 32KB in chunks using writer streams.
- Support ephemeral websocket sessions for sessionless execution and enrich disconnect logs with session kind and terminal event context.
Closes: #5734
- Removed deprecated interceptor and executor-related methods, including `callRequestInterceptor`, `callResponseInterceptor`, and `callStreamChunkInterceptor`.
- Consolidated unused logic and pruned redundant imports to streamline `adapters.go`.
