agno uses useFrontendTool (Strategy B) — async Promise handler in the
frontend — rather than LangGraph's native interrupt() primitive. The D5
probe asserts via useInterrupt hook which routes through the LangGraph
interrupt event path. agno doesn't emit those events; the D5 probe
fundamentally cannot pass against agno's HITL architecture without
per-integration probe-code divergence (which would violate the D6
apples-to-apples invariant).
Excluding these two features at the manifest level (matching google-adk
precedent) lets the D6 probe skip them cleanly. Removes the
corresponding D6 aimock fixtures since they're no longer reachable.
If agno gains LangGraph-style interrupt() support, or if aimock gains
AG-UI-event fixture authoring, this exclusion can be reverted.
Adds per-integration D6 fixtures for langgraph-python, langgraph-typescript,
and langgraph-fastapi. Each fixture is keyed by match.context for cross-
integration isolation and uses hasToolResult:false on toolCall responses
to prevent re-match loops.
Move monolithic d5-all.json + feature-parity.json + smoke.json into
per-integration directories under d4/<slug>/, d6/<slug>/, and shared/.
Every fixture file is now context-scoped to enable server-side aimock
routing via match.context. Migrated 12 HITL fixtures from main's
d5-all.json additions into shared/_migrated-from-d5-all-hitl.json
for follow-up distribution into per-integration files.
