Problem
The SessionService processes active sessions using findSessionsToSummarize by collecting them into a map and iterating over them with Object.keys(). This groups candidate sessions but processes them in an arbitrary iteration order rather than chronological priority. As a result, the newest active sessions might wait while older unsummarized items in the backlog are digested.
Solution
- Refactored
findSessionsToSummarize to track the lastActivity (highest memory timestamp) for every categorized session.
- Explicitly applied a descending sort to the
sessionsToUpdate array based on the lastActivity timestamps prior to returning it.
- Authored a new Playwright test in
SessionSummarization.spec.mjs with simulated session intervals to strictly enforce that the newest session is processed internally before older sessions.
Impact
Future agent iterations will accurately ingest their freshest historical context first natively out of the gate. This resolves "Zero-State Amnesia" for restarted sessions and guarantees token allocation prioritizes immediate memory over the backlog.
