📝 WalkthroughWalkthroughThe Linear adapter adds a reconciliation function that paginates session activities, matches mapped activity content, and returns a matching activity ID. It also adds a request action, public exports, and tests for pagination and error cases. ChangesLinear AgentActivity Reconciliation

Avoid comparing timestamps from different clocks
When createdAtOrAfter is captured by the consumer before its first write attempt, it comes from the consumer's clock, while createdAt comes from Linear's clock. If Linear's clock is even slightly behind, an activity that actually landed can have createdAt < createdAtOrAfter; this comparison then ignores it and eventually returns found: false, causing the caller to retry and create the duplicate this helper is intended to prevent. Fresh evidence after 7ffa783c is that the new boundary is compared directly with zero skew tolerance; use a provider-derived cursor/known-ID boundary or otherwise account for cross-system clock skew.

Summary
Validation
Follow-up: AgentWorkforce/cloud#4017 will consume the published adapter export.
Note
Medium Risk
New writeback reconciliation path affects agent session terminal activities; incorrect matching or overly strict validation could duplicate or block legitimate activities, though the design fails closed on ambiguous provider data.
Overview
Adds
reconcileLinearAgentActivityto@relayfile/adapter-linearso callers can confirm whether a terminal AgentActivity already landed after an ambiguous create, instead of posting duplicates.The adapter owns the
list_agent_activitiesGraphQL contract (RelayfileAgentSessionActivities), cursor pagination with repeat-cursor detection, strict parsing of session history, and exact matching of frozen activity content (type, body, and action fields) for nodes at or after a caller-supplied time boundary. Provider errors, malformed envelopes, incomplete nodes, and invalid cursors fail closed with errors; a clean scan returns{ found: false }or{ found: true, externalId }.The helper and types are re-exported from the package entry and
