The general-purpose default agent (agent.py, catch-all `/` endpoint) still
carried a hand-rolled `generate_a2ui` (raw secondary OpenAI call to
`_design_a2ui_surface`). Removed it: the default agent no longer offers A2UI at
all, matching the langgraph-python default agent. The main route enables no A2UI
middleware, so this was latent/dead A2UI anyway.
- agent.py: drop the hand-rolled generate_a2ui tool + its import.
- render-a2ui.json: strip the stale `_design_a2ui_surface` fixture entries (the
native `render_a2ui` + generate_a2ui entries remain).
- e2e specs: refresh the declarative-gen-ui + beautiful-chat comments that
described the old `_design_a2ui_surface` mechanism to the native auto-inject path.
The shared `tools/generate_a2ui.py` module is intentionally kept: it is symlinked
by other integrations (ag2, agno, ...) that still hand-roll A2UI; MAF-python
simply no longer imports it. After this, the MAF-python integration has ZERO
hand-rolled A2UI anywhere except the fixed-schema demo (which is the intended
fixed-schema pattern, identical to langgraph). Full D6: all A2UI + default-agent
cells green.
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.
