PR #8340 - simstudioai/sim

Summary

Add Linear, Fireflies, Granola and Notion to live Search using the existing account and authorization pipeline.
Include GitHub PR comments, reviews and inline discussions, plus Drive comments and replies, in document reads.
Share managed MCP read validation, make provider limits explicit in query guidance, bound streamed MCP events, and update the Granola icon.
Coordinate the matching worker contract and query guidance.

1,381 provider, authorization, legacy Search, MCP and integrations UI regression tests passed; nine real Postgres setup/rollback/concurrency tests passed.
Failure-first checks for argument validation, repeated cursors, oversized streamed events and structured transcript attribution.
Live Fireflies, Granola and Notion agent acceptance: 10 questions across 14 executions, with source facts and citations checked. Response latency: 8.172–18.776s, median 13.321s.
GitHub discussion and review acceptance against independent provider queries: seven positive cases plus five date-bound cases passed 30 checks. Real conversation and inline-comment matches are tied to their original comment IDs. Negative controls reject title-only or unrelated-comment evidence, absent review results, and contradictory approval expectations. Mixed queries verify separate issue and PR result limits. Approval expectations cover submitted review events; the adapter acceptance checks native inclusive date candidates, while application date filtering is covered separately. Linear OAuth was not included in live acceptance.
Type-check across 26 workspaces, lint, generated artifact checks, block-registry audit and all 51 audits passed.
