observations:
- host: dev.sapientslingshot.com
  finding: >-
    TLS certificate expired. The wildcard *.sapientslingshot.com certificate issued by
    GoDaddy Secure Certificate Authority - G2 ran from 2025-05-09 to 2026-05-09 and was
    still being served on 2026-09-13, so the host fails default certificate validation.
    Probed 2026-09-13.
- host: dev-slingshot.sapientaiproducts.com
  finding: >-
    dev.sapientslingshot.com redirects here, and this host answers HTTP 200 with a
    Prometheus exposition payload (Content-Type text/plain; version=0.0.4) for every path
    probed, including /, /docs, /health and /openapi.json. It is an unauthenticated
    metrics endpoint on a development deployment, not an API contract, and no spec was
    derived from it. Probed 2026-09-13.
- scope_note: >-
    Hosts probed by the script are those named in apis.yml. sapientslingshot.com and
    sapientaiproducts.com are not apis.yml hosts; the two findings above were recorded
    during contract discovery.
