// A2UI error recovery (OSS-158 / OSS-375). Assert the STABLE end-states — the
|
|
// recovered surface paints (heal) and the hard-failure UI shows (exhaust) — and
|
|
// deliberately do NOT assert the transient "Retrying generation… (N/M)" label,
|
|
// which is threshold-gated + timing dependent (see @copilotkit/react-core/v2
|
|
// A2UIRecoveryStates) and would be flaky.
|
|
//
|
|
// The aimock fixtures (showcase/aimock/d6/langgraph-python/a2ui-recovery.json)
|
|
// drive the inner render_a2ui sub-agent two ways: HEAL emits free-form/sloppy
|
|
// args (components/data as JSON strings) the middleware heals via parse_and_fix;
|
|
// EXHAUST is structurally invalid (unresolved child) on every attempt, so the
|
|
// validate->retry loop hits the cap and returns the a2ui_recovery_exhausted
|
|
// envelope. Healing + the loop run live in the backend ag_ui_langgraph
|
|
// get_a2ui_tools factory (injectA2UITool=false); the failure UI text ("Couldn't
|
|
// generate the UI") comes from @copilotkit/react-core/v2. The recovered surface
|
|
// reuses the declarative-gen-ui catalog, so it carries the `declarative-metric`
|
|
// testid.
|
|
//
|
|
// Requires the stack running with aimock so the malformed renders fire
|
|
// deterministically; against a real LLM the demo would not reliably produce the
|
|
// invalid attempts.
