Namespace guard for merged toolboxes

The four tools target distinct artifacts: audit, census, verdict query, and receipt verification. There is slight potential overlap between audit_toolbox and query_verdict, since both concern collision evaluation, but the descriptions make their roles reasonably clear.

All tools follow a consistent snake_case verb_noun pattern: audit_toolbox, get_census, query_verdict, verify_receipts. The convention is predictable throughout.

Four tools is well-scoped for a namespace guard focused on collision auditing, name census, verdict lookup, and receipt verification. Each tool appears to earn its place without unnecessary surface area.

The set covers auditing, census retrieval, verdict checking, and receipt-chain verification, which are the core guard operations. Minor gaps may exist around explicitly resolving collisions or managing claimed names, but the available surface supports the stated purpose.
