Capture lastGlobalSequence() before any projection read to anchor the buffer-drain window; capture lastSequence(sessionId) before each session's projection read. SessionSnapshot.lastSequence now carries the global cursor shared across all sessions in the batch. pendingApprovals populated from filtered approval state and sorted by (timestamp, requestId) for deterministic ordering. SnapshotComplete emitted unconditionally including the zero-sessions case. Four new tests: zero-sessions, SnapshotComplete-last ordering, global cursor isolation, and per-session cursor value.
