## Changelog

### 0.1.0 — 2026-09-25

- Discover concrete subdomains from recent public certificate-transparency issuances for supplied authorized root domains.
- Export current A, AAAA, and CNAME answers alongside issuance ID, certificate dates, issuer, and check time.
- Exclude wildcard-only names and cap issuance pages; this is not exhaustive DNS enumeration or a service-availability test.
