Compare source coverage on exactly the same declared record cohort across two snapshots. Report per-record gained/lost sources, per-source count changes, and global coverage drift. Reject unknown sources or missing/duplicate records. Coverage does not establish source quality. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Compare up to 80 expected and 80 observed document descriptors against one declared tenant and scope. Flags missing, unexpected and cross-tenant documents; incomplete scope stays undetermined. Public/synthetic metadata only. Not access-control enforcement, corpus completeness or legal verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
