Abstractions for the Altcha-based proof-of-work module:
- AltchaAttribute (AllowMobileAttestationBypass param)
- IHasAltchaSolution — marker interface for request POCOs carrying
the widget's solution payload over HTTP/gRPC transports
- IAltchaVerifier / IAltchaChallengeProvider — transport-agnostic
interfaces; default gRPC implementations ship in Svrnty.CQRS.Altcha.Grpc
- IMobileAttestationProvider — Phase 3 placeholder; concrete impls
stamp ctx.Items["mobile_attested"] for the Altcha check to read as
a bypass when AllowMobileAttestationBypass is true
- AltchaChallenge / AltchaVerifyResult DTOs
Lean dependencies — only references Svrnty.CQRS.Abstractions for the
auth-check pipeline types.
