Resolves the server's canary zone through the platform resolver and
compares against the spec-frozen ground truth (probe-protocol §6.1):
reference records detect answers rewritten in flight, and a per-run nonce
name (uncacheable) proves the query reached the authoritative server.
Findings: dns.answer_rewritten (high), dns.authoritative_unreachable
(medium).
Verified on the OnePlus against the deployed fmr zone: 4/4 reference
records matched exactly, nonce name answered 192.0.2.21 with
reached_authoritative=true. First full client<->server measurement loop
on real hardware; report archived.
