The Apr 21 "refactor(runtime): Support durable compaction of threads" commit
re-added a2ui_dynamic_schema.py and a2ui_fixed_schema.py to the
langgraph-python-threads example in a stripped form. Most of the simplification
was cleanup, but two docstrings carried load-bearing instructions for the
sub-LLM and those got lost:
- render_a2ui's Args block said the root component must have id "root".
Without it, the LLM emits a valid flat component list with no entry point;
the A2UI renderer (A2uiSurface.tsx:152) hard-codes id="root" and falls
through to a shimmer placeholder — the "Sales Dashboard (A2UI Dynamic)"
demo renders as an empty white square.
- search_flights' docstring spelled out airline logo URLs, date format,
and status-icon colors, producing consistently-styled flight cards.
This restores both files verbatim from the non-threads example, which is
the known-good template. All differences in the agent/src dir are now
removed. Debug prints and headers come back with the restore; happy to
trim them in a follow-up if the intent was to keep the -threads version
terser.
