What

• Resume SSE connections with the last received domain-event ID, allowing kmrs to replay retained events before returning to the live stream.
• Parse SSE frames line by line, including event IDs, multi-line data, heartbeats, and id-less task snapshots.
• Scope cursors to the current account and reset them on login, logout, and server switches while preserving them across lifecycle suspension and preference toggles.
• Isolate old streams and delayed reconnects so they cannot overwrite the state of a newer connection.

Why

kmrs now supports bounded replay of missed SSE events. KMReader previously discarded event IDs, so a temporary connection gap could miss content changes. The cursor is intentionally memory-only and best-effort; an expired or foreign cursor starts live without requiring a custom recovery event.

Validation

• make format
• make build — iOS, macOS, and tvOS all passed.
• Installed the iOS build in the iPhone 18 Pro simulator and verified against the configured kmrs server: initial SSE connection and disabling/re-enabling Real-time Updates both succeeded.
• The test server emitted no domain event during the simulator check, so an actual replay and the outbound Last-Event-ID header were not observed end to end.
