Module session_index 

Revisioned session-list subscriptions for latency-sensitive frontends.

Native filesystem events are treated as invalidation hints, never as the session record itself. Each hint causes a bounded re-read of the affected Claude Code or Codex transcript; a slow periodic catalog reconciliation repairs dropped/coalesced platform events and fills a page after removals.

Structs

SessionIndexDelta

One subscription poll result. Revisions start at one for the initial snapshot and increase by exactly one for each non-empty delta batch.

SessionIndexKey

Stable public identity for a session-index change. Persistence paths remain inside the trusted host and are sent only as part of complete descriptors.

Enums

SessionIndexChange

One complete replacement in a revisioned index delta.
