Mirrors LGP's `generate_a2ui` outer-emit fixture into 8 non-LGP slugs to close
the production 503 gap on the "Show me my sales dashboard for this quarter."
userMessage. Per /tmp/staging-journal-diff.md, aimock-staging returns 503 on
shape-B traffic (model=gpt-4.1, stream=true, tools=[generate_a2ui],
UA=AsyncOpenAI/Python) for all 8 slugs because no fixture matched.
Slugs patched (one entry each in d6/<slug>/gen-ui-declarative.json):
- llamaindex
- built-in-agent
- ag2
- langroid
- claude-sdk-typescript
- claude-sdk-python
- ms-agent-dotnet
- ms-agent-python
Each entry matches `userMessage` + `context: "<slug>"` and emits a
`generate_a2ui` toolcall with no args, mirroring LGP's sales-dashboard outer
entry. Per-slug unique toolCallId.
Red-green proof (local aimock, ghcr.io/copilotkit/aimock:latest):
RED (baseline main, 8 slugs): HTTP=404 no_fixture_match
GREEN (this branch, 8 slugs): HTTP=200 tool=generate_a2ui id=call_d6_decl_dash_outer_<slug>_001
LGP regression (baseline+fix): HTTP=200 (unchanged)
aimock fixture validation: 737/737 tests pass.
PR scope is intentionally narrow per CLAUDE.md "Scope PRs to flagged
findings": this closes ONE userMessage gap. Shape-A 503s (no tools key) and
other userMessage gaps remain as separate follow-ups.
Same pattern as ms-agent-dotnet: full d4 chat.json rewrite + d6 mirrors. Dropped stale
turnIndex gates and broad shadow matchers. Default-catchall now green via page-level
shadcn-catchall-renderer. 11 residual: declarative-gen-ui charts, multimodal conveyance,
tool-rendering, reasoning-chain.
Refresh d6 fixtures across the rollout cohort: ag2, built-in-agent,
claude-sdk-{python,typescript}, crewai-crews, google-adk, langgraph-fastapi,
langgraph-typescript, langroid, llamaindex, mastra, ms-agent-{dotnet,python},
pydantic-ai, strands. Companion d4/{langgraph-typescript,mastra,ms-agent-dotnet}
chat.json refreshes. Add the missing ms-agent-python/gen-ui-custom.json
to bring the integration up to the standard pill set.
Also narrow aimock/shared/common.json's generic 'hello' fixture to
'hello world' so it no longer shadows D6 pills whose prompts contain
'hello' as a substring (e.g. langgraph-python headless-simple sends
'Say hello in one short sentence.'). 'hello world' is unused by any
current demo pill, so the fixture remains a manual-typing fallback
without poisoning fixture matching.
This is a mid-rollout snapshot — fixture coverage is uneven across
integrations and rides alongside the conveyance shims landed earlier
in this branch.
