Parent commit 9491b8934 (fix(showcase): disjoint catchall userMessages + content-asserting probes) changed the d5-tool-rendering-custom-catchall probe userMessages to 'Forecast Tokyo through the wildcard renderer' / 'Quote AAPL through the wildcard renderer' but did not add matching entries to LGP-gold's fixture. Result: aimock no-match -> agent_run_error_event -> SSE-missing -> probe RED on LGP with zero bubbles mounted.
This commit adds 4 entries (2 emit + 2 toolCallId-gated narration) following the canonical pattern used by the other 17 integrations. After this commit, LGP bubbles mount and narrations settle with the canonical phrase in bubble.textContent, matching BIA's end-state.
NOTE: A separate fleet-wide probe-layer bug (validateCustomCatchall's customContentPhrasePresent page-wide DOM scan returns false even when phrase is in bubble.textContent) keeps the probe RED in this session. That's a separate concern, to be fixed in a follow-on commit. This commit is a strict improvement: pre-fix LGP got zero bubbles + agent_run_error_event; post-fix LGP renders both bubbles and both narrations settle with the phrase.
(cherry picked from commit 62e04976c3b292a27e1b1cc0bf2bb6fda47db786)
Aimock fixture load order is shared -> d4 -> d6, and matching is first-match-wins. A
broad d4 langgraph-python chat fixture for search_flights was shadowing the d6
beautiful-chat fixture and preventing the intended response from firing. Neutered the
d4 matcher to a non-matching sentinel so the d6 fixture wins.
Also refreshed d6/tool-rendering-custom-catchall.json and d6/tool-rendering.json:
replaced fragile turnIndex:0 gates with hasToolResult:false so the AAPL first-leg
fixture fires correctly when D5 probes run a prior 'weather in Tokyo' pill in the
same thread (multi-pill turnIndex>=2).
LGP D6 now passes 185/0/2 locally (2 skips are the by-design mcp-apps iframe gap).
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.
