## Changelog

### 0.1 - 2026-06-12

Initial release.

- Web tech-stack fingerprint engine: 90+ technology rules across 12 categories
  (CMS, ecommerce, analytics, marketing, frameworks, hosting, payment, web
  server, widgets, advertising, fonts, security), matched offline + deterministically
  over fetched HTML, `<script>` srcs, response headers, and Set-Cookie names,
  with per-detection confidence, version capture, and evidence.
- Four modes: `tech_stack`, `find_by_technology`, `new_domain_intel`,
  `tech_change_monitor`.
- New-domain / registration intel via public RDAP (the GDPR-era WHOIS
  successor): creation/expiry dates, registrar, nameservers, domain age, and a
  new-domain sales-trigger flag. PII-minimized by design.
- Monitor mode: re-fingerprints a watchlist and diffs each domain's tech set
  against the previous scheduled run, surfacing "added Shopify / dropped HubSpot"
  change triggers with a Slack/email digest.
- Three-tier anti-bot escalation ladder (httpx -> curl\_cffi TLS impersonation ->
  optional Playwright), fail-soft when blocked.
- Full cost-control stack: pre-flight input caps, demo-mode soft-fail,
  `_RunBudget` guard, in-loop budget checks, hardcoded PPE prices.
- Pay-per-event pricing: `domain_record` $0.004, `tech_stack_enrichment` $0.008,
  `new_domain_trigger` $0.010, `scheduled_delta_run` $0.010.
- Normalized dataset schema with overview / detailed / per-technology views,
  next-actions, and HTML/CSV output artifacts.
