These are the load-bearing documents. Read in any order; the suite is internally consistent. Architecture and protocol surfaces are stable for review and integrator implementation. Forthcoming items are listed at the bottom.
The full architectural argument. Establishes per-commitment cost-linearity as a structural — not parametric — consequence of composing time-binding, memory-hardness, and physical-state witnessing against a stated threat model. Defines the in-scope adversary and the explicitly bounded acknowledged limits.
The construction paper. Specifies the bracketed interval (lightweight 6-block and heavyweight 144-block tiers), the memory-hard work profile, sensor-coherence acceptance thresholds, anchor-transaction confirmation depth, and reorg handling. The mechanical basis for the cost-positivity property.
Canonical terminology. Defines envelope, burn, anchor, commitment, attribution, check-in, cosign. Reconciles the two-phase architectural framing with the construction-level burn / establishment / verification phasing. Authoritative for any term in the suite.
Design specification for the public attribution layer. Sparse-Merkle structure in the lineage of Certificate Transparency and CONIKS; Bitcoin-anchored epoch roots; authenticated range-query semantics sufficient to detect omission. Operator-neutral by construction.
Normative operator behaviour. Specifies proof formats, the inclusion-vs-construction verification boundary (§7), and the proof_internals slot layout. Operators are untrusted for correctness; the Bitcoin chain is the trust anchor.
The two practical patterns: check-in (presenting a commitment as a credential) and cosign (binding a commitment to a DID, verifiable credential, or Nostr npub). Demonstrates that the primitive composes with — rather than replaces — existing identity frameworks.
Architectural framing for systems that wish to recognise commitments as credentials. Lays out the verifier-policy surface: weighting, attribution interpretation, and composition with existing account identifiers.
Defines the in-scope adversary (substantial capital, virtualisation tooling, operational sophistication) and the methodology by which the per-commitment cost floor is composed from a finite set of structural levers. Calibration is parametric; cost positivity is structural.
Methodology for auditing verifier policies and accepting-system behaviour. For any party evaluating an Orange Anchor deployment against its stated security claims.
Calibration Annex · Adversarial Scenario Analysis · Integrator Quick Start · Orange Anchor Technical Paper · Reference Implementation. Architecture and protocol surfaces in the current suite remain stable across these additions.
