GHSA-6GQW-JQV7-V88M stigmem-node: decay sweep expires and counts facts across all tenants (cross-tenant BOLA)

Summary On a multi-tenant stigmem node, a caller holding a write credential for one tenant can run a decay sweep that acts on every tenant's facts. The candidate-selection queries in lifecycle/decay.py selectttlcandidates, selectconfidencecandidates carried no tenantid predicate, and the caller's...
