OPA Meeting Context Bridge

Server-side, provider-neutral bridges from existing Notion, Slack, email, Drive/document, CRM, and governed-web read surfaces to OPA's MeetingContextSourcePort.

Every factory is bound to one exact OPA owner scope, applies explicit item and content bounds, emits hashed provenance/citation references, and propagates provider or contract failures. Shared sensitive material requires a configured consent reference.

Hosts inject already-authorized provider instances and meeting-specific query/match functions. The included Google Drive v3 REST provider resolves a fresh bearer through a server-only token port, supports shared-drive listing, and streams bounded blob or Google Docs text into the governed Drive bridge. The included HubSpot CRM provider uses the official date-versioned 2026-03 read endpoints for contacts, companies, and deals. It resolves fresh bearer authority server-side, requests only allowlisted properties, binds pagination to the exact tenant/workspace/entity-kind scope with a host-supplied HMAC key, and requires a durable evidence receipt for every projected object. Salesforce remains contract-backed only. CompanyOS company intelligence is intentionally not duplicated here because its existing Work Graph meeting source owns that boundary.
