Sparkyfitness Domain Security

finding: >-
  SparkyFitness controls no domain of its own. There is no vendor API host to
  probe (the product is self-hosted, so every API host belongs to an operator)
  and the only surface the project publishes is a GitHub Pages site under
  codewithcj.github.io. The automated pipeline probe returned `no-hosts` for
  exactly this reason — pipeline_util.provider_hosts deliberately excludes
  github.io, because the TLS, HSTS and DNS posture of a Pages host measures
  GitHub's infrastructure, not the project's. The results below are recorded
  with that attribution made explicit, and MUST NOT be read as a security
  posture SparkyFitness chose or maintains.

interpretation: >-
  For a self-hosted product the domain-security dimension is genuinely not the
  project's to answer, and scoring it as a gap would misattribute GitHub's
  configuration to SparkyFitness. What IS the project's to answer, and what it
  does answer, is the security posture of the software an operator deploys:
  PostgreSQL row-level security on every user-scoped read, admin-gated
  developer tools that are off by default, MFA with an admin mandatory-MFA
  switch, WebAuthn passkeys, OIDC federation, nginx rate limiting on every
  authentication endpoint, and per-API-key rate limits. Those are recorded in
  authentication/sparkyfitness-authentication.yml and
  rate-limits/sparkyfitness-rate-limits.yml.
