Status​

This is the current path-aware and contract-aware coverage-audit baseline for alpaca-rust.

  • The machine-readable manifest exists.
  • The audit entrypoint exists.
  • Path-level adopted-family coverage checks are wired.
  • Parameter-level and response-level drift checks are wired against the current manifest contract snapshots.
  • Planned gaps and untracked official families are surfaced.
  • Explicit exclusions are tracked in the manifest instead of being left as silent unknowns.
