Default Settlement Specifications
Technical standards and reference documentation for settlement receipts, verifier interfaces, continuity checks, and execution-boundary evidence.
Naming hierarchy — do not collapse these
- Default Settlement — the trust/evidence system and company-level architecture.
- DefaultVerifier — the deterministic verification engine inside that system.
- SAR — Settlement Attestation Receipt; the core evidence object Default Settlement authored.
- Continuity — the long-term trust/history layer built from repeated verified SARs.
- Trust Passport — the public trust-history surface generated from verified SAR history.
- Explorer — the public inspection surface for receipts, agents, and evidence.
- SAR-402 — an x402-specific profile of SAR, not the whole system.

Execution Boundary
Continuity v0.1
A model for evaluating whether governing invariants survive to the mutation boundary.
Failure Case
Continuity Failure Example v0.1
A concrete example showing why valid authorization alone is not enough.
