workset_overlay

A bounded mutable workset with authoritative, complete boundary adjacency.

WorksetOverlay 

WorksetOverlay(durable: Any, cycle: str)

Bases: ScopeOverlay

Retain candidates separately from read-only endpoint context.

Candidate scans see only this cycle's page. Identity and neighbour lookups can load bounded boundary context, without promoting that context into the candidate list. An incomplete read invalidates the whole journal even if a legacy phase catches the exception and attempts to continue.
