Mechanism

The mechanism comprises cooperating components disclosed for the N-party coordination settlement primitive: a participant-admission interface that ingests governance-credentialed observations from N authority-credentialed parties, where N is three or more; a coordination-pattern selector applying a governance-policy-defined coordination pattern that specifies the roles of each party and the rules for producing the coordinated outcome; a role-differentiated attestation schema specifying the per-role observation content for each participating party; and a coordination-outcome function that evaluates the contributed observations to determine the coordinated outcome per a governance-policy-defined function. The role assignment is a governance-policy parameter of the deployment rather than a fixed enumeration built into the architecture, so the same primitive serves a plurality of coordination patterns without architectural modification.

At coordination initiation the participant-admission interface ingests each party's governance-credentialed observation. A spatial-proximity evaluator verifies participant spatial proximity per the mesh-derived coordinate primitive, and a temporal-proximity evaluator verifies participant temporal proximity per the mesh-derived time primitive, grounding the coordination in physical spatiotemporal proximity rather than in shared global state. A per-participant admissibility evaluator then applies the composite admissibility evaluator to each contributed observation, so that each party's contribution is admitted, gated, or rejected before it enters the outcome determination.

The role-differentiated attestation schema specifies what each role must contribute. Each contributed observation is a governance-credentialed observation carrying the contributing party's authority credential, and a weighted-participation mechanism supports authority-tier-weighted contributions so that the evidential weight of a party's attestation follows its position in the authority taxonomy. The schema specifies per-role observation content for each participating party; the role assignment and the rules for producing the outcome are specified by the governance-policy-defined coordination pattern.

The coordinated outcome is produced by the coordination-outcome function over the contributed observations. The coordination-lineage recorder records each participant admission, attestation, and outcome determination in the governance chain lineage field, so that downstream audit can reconstruct who contributed which governance-credentialed observation under which role and how the outcome function combined them. Because the contributed observations carry per-participant authority attribution, the resulting settlement is governance-credentialed rather than a flat aggregate of equivalent signatures.

Operating Parameters

The operating parameters of an N-party coordination deployment are supplied through per-deployment governance-policy parameterization, which specifies the coordination pattern, the role assignment, the outcome function, and the membership composition without architectural modification. The role assignment is selected for the operational domain by governance policy rather than hard-coded into the architecture. The primitive operates across consensus-required decisions, quorum-based resolutions, auctions, role-differentiated coordinations, lead-and-follower formations, custody-transfer chains, federated-contribution aggregations, multi-authority approvals, multi-source attestation aggregations, and governed voting.

Per-participant admission is governed by the composite admissibility evaluator, which is applied to each contributed observation to determine whether it is admitted, gated, or rejected, together with the spatial-proximity and temporal-proximity evaluators that verify participant proximity. Evidential weight follows the weighted-participation mechanism's support for authority-tier-weighted contributions, so a party's contribution is weighted according to its level in the authority taxonomy. The governance-policy parameterization determines these admissibility and weighting rules; the spec does not fix particular threshold counts or proximity windows.

The coordination-outcome function determines how the contributed observations combine into the coordinated outcome under the governance-policy-defined coordination pattern. The primitive further supports a multi-round coordination engine for iterated ceremonies converging to a terminal outcome; a Byzantine-robust coordination mechanism tolerating a governance-policy-defined fraction of adversarial or failed participants; a partial-quorum and abandonment handler managing incomplete ceremonies; and a dynamic-membership mechanism supporting member replacement during ceremonies. Each round transition, Byzantine event, abandonment, and membership change is recorded by the coordination-lineage recorder in the governance chain lineage field.

Alternative Embodiments

A first alternative embodiment supports cross-domain coordination handoff. When a coordinated operation crosses an authority-domain boundary, a cross-domain coordination handoff mechanism transfers it between a relinquishing-domain authority and a receiving-domain authority without loss of governance continuity, lineage continuity, or coordination-state continuity. A cross-authority taxonomy translator per Chapter 28 reconciles authority context, observation schemas, and applicable policies across taxonomies; a graduated handoff-confidence governor modulates receiving-authority acceptance by cross-authority evidential weight; and a matched-pair handoff settlement per Chapter 20 records the handoff as a lineage-linked pair. Disclosed handoff instances include intermodal freight handoff among sea-freight, rail-freight, and road-freight authorities; airspace-transition handoff between flight information regions or between civil and military airspace; and medical patient-transfer handoff across emergency-medical-services, hospital, surgical, post-operative-care, and post-discharge-primary-care authorities.

A second alternative embodiment supports cross-pattern composition. A cross-pattern composition mechanism combines multiple coordination patterns within a single ceremony, so that, for example, a consensus-required decision among one set of parties and a quorum-based resolution among another set compose into a single coordinated outcome. The composition is governed by the same governance-policy parameterization that specifies each constituent pattern's role assignment and outcome function, and the composition event is recorded by the coordination-lineage recorder.

A third alternative embodiment supports multi-round coordination. A multi-round coordination engine supports iterated coordination ceremonies converging to a terminal outcome, with each round transition recorded in the governance chain lineage field. A Byzantine-robust coordination mechanism tolerates a governance-policy-defined fraction of adversarial or failed participants, and a partial-quorum and abandonment handler manages ceremonies that do not reach completion.

A fourth alternative embodiment supports dynamic membership. A dynamic-membership mechanism supports member replacement during a ceremony, so that a participant that departs or fails can be replaced by a substitute admitted through the same participant-admission interface and the same composite admissibility evaluation. Each membership change is recorded by the coordination-lineage recorder, preserving the provenance of the ceremony across the substitution.

Composition With the n-Party Primitive

Role-differentiated attestation is a facet of the N-party coordination settlement primitive disclosed in 64/049,409, which extends the bilateral matched-pair settlement primitive of Chapter 20 to arbitrary N-party ceremonies among three or more authority-credentialed parties. The role-differentiated attestation schema specifies per-role observation content, and the governance-policy-defined coordination pattern specifies the roles of each party and the rules for producing the coordinated outcome. Participant admission, through the participant-admission interface and the per-participant composite admissibility evaluation, precedes outcome determination over the admitted contributions.

The coordination-outcome function is the structural locus of role differentiation. It is a governance-policy parameter of the coordination that evaluates the contributed observations to determine the coordinated outcome, and the weighted-participation mechanism supports authority-tier-weighted contributions so that a party's evidential weight follows its level in the authority taxonomy. Because the coordination pattern, role assignment, and outcome function are governance-policy parameters rather than fixed rules, the same architecture supports consensus-required decisions, quorum-based resolutions, lead-and-follower formations, and the other disclosed coordination patterns without architectural modification.

The N-party coordination settlement primitive composes across the governed spatial mesh. It composes with the governed mesh protocol of Chapter 2 through multi-party observation emission, with the cross-domain coherence evaluator of Chapter 4 through multi-source attestation fusion, with the mesh-derived coordinate primitive of Chapter 16 through spatial-proximity evaluation, with the mesh-derived time primitive of Chapter 17 through temporal-proximity evaluation, and with the matched-pair settlement primitive of Chapter 20 through pairwise component settlements within multi-party ceremonies. The coordination-lineage recorder makes the composed ceremony reconstructable end-to-end from the governance chain lineage field.

Prior-Art Distinction

Prior multi-signature cryptographic schemes, including m-of-n and threshold signatures, cryptographically aggregate signatures without attaching authority-chain semantics, whereas the present primitive produces governance-credentialed settlements with per-participant authority attribution. A threshold signature satisfied by any m of n signers does not carry the role under which each party contributed or the authority-tier weighting of each contribution; the present primitive records each contributed observation under its role assignment in the governance chain lineage field.

Prior blockchain consensus protocols, including proof-of-work, proof-of-stake, and Byzantine fault tolerance variants, require global agreement about shared state across all network participants, whereas the present primitive requires coordination among specific named parties only. Prior auction protocols handle specific single-commodity auctions without governance-chain integration, and prior voting protocols handle public-choice selection without multi-pattern composition, whereas the present primitive generalizes across coordination patterns with governance-chain preservation and admits composition across patterns.

Prior multi-party computation protocols enable privacy-preserving joint computation without coordination semantics, whereas the present primitive integrates coordination with privacy governance per Chapter 10. Prior architectures do not support role-differentiated attestation with pattern-agnostic outcome-function parameterization, do not support cross-domain coordination handoff preserving governance continuity across authority boundaries, and do not ground coordination in physical spatiotemporal proximity, whereas the present primitive requires participant spatial-temporal proximity and integrates multi-round coordination, Byzantine robustness, partial-quorum handling, and dynamic membership through a unified mechanism.
