Mechanism
The per-segment attestation mechanism associates each marker-track segment with an authority-credentialed attestation carried by the governance-credentialed markers that encode the segment. The attestation is not a separate document referencing the segment by identifier; it is carried by the marker sequence itself, such that any transport unit reading the markers along a segment necessarily reads the attestation of authorized transport-unit use alongside the topology the markers encode. Among the attributes a marker carries are a marker identifier, an authority credential of the authorizing freight-track, transit, or transport authority, a governance-policy-defined topology payload, a temporal-validity specification, a cryptographic integrity attestation supporting marker-read authenticity evaluation, a revision-version indicator supporting governance-chain-preserving marker updates, and a marker-lineage reference supporting provenance reconstruction of the marker's authorization.
The authority credential names the authorizing freight-track, transit, or transport authority and is evaluated against the unit's operator class and authority credentials. It is not a free-form string; it resolves through the governance chain so that the marker's authority can be verified at each marker read, and a unit preparing a route verifies each segment's authority credential against the unit's operator class and authority credentials before the segment is admitted to the route manifest. Where a marker read fails authority verification, the marker-read admissibility evaluator rejects it rather than admitting it unconditionally.
The temporal-validity specification includes an issuance timestamp and a governance-policy-defined expiration. A marker-temporal-consistency evaluator verifies that the marker's temporal validity is consistent with mesh-derived time, so that a marker whose validity window has lapsed, or whose claimed validity is inconsistent with the unit's mesh-derived time, can be detected at read time rather than relied upon. The temporal-validity specification governs how long a given segment authorization remains in force and is one input among several to the marker-read admissibility evaluation.
The governed operational parameters name the conditions under which a unit may operate on the segment. Linear-segment markers encode segment geometry including curvature, grade, speed envelope, lane assignment, and permitted vehicle classes. A single marker-track infrastructure serves all operator classes concurrently with per-segment governance specifying permitted vehicle classes and operational parameters, so that a unit operates within the segment's governed speed envelope, lane assignment, and regulatory overlay as named by the segment's own attestation rather than by a route-wide policy.
Operating Parameters
Each marker carries a plurality of attributes. The marker identifier names the marker. The authority credential names the authorizing freight-track, transit, or transport authority. The governance-policy-defined topology payload encodes the segment's topology, including for linear-segment markers the curvature, grade, speed envelope, lane assignment, and permitted vehicle classes. A marker-precision characterization indicates the position-reference precision the marker provides. The temporal-validity specification carries an issuance timestamp and a governance-policy-defined expiration. A cryptographic integrity attestation supports marker-read authenticity evaluation. A revision-version indicator supports governance-chain-preserving marker updates, and a marker-lineage reference supports provenance reconstruction of the marker's authorization. The specification enumerates these attributes without limitation rather than fixing a closed field count.
Topology updates are committed through a governance-approval mechanism rather than by in-place revision without record. The topology-update mechanism receives governance-credentialed update requests from authorized authorities, applies governance-policy-defined update admissibility rules, notifies affected operator-class fleets of pending updates, commits approved updates to the marker infrastructure with cryptographic revision-version attestation, and records each update request, admissibility determination, stakeholder notification, deployment, and downstream consequence in a topology-update lineage record. This discipline preserves the governance chain across authorization, revision, and retraction of a track segment.
The cryptographic integrity attestation is produced under a cryptographic attestation mechanism supporting the governance-chain properties. The architecture is agnostic to the specific primitive; the specification describes the attestation as produced under a digital-signature algorithm, a threshold-signature algorithm, a zero-knowledge attestation, a post-quantum attestation, or any equivalent cryptographic attestation mechanism supporting the governance-chain properties. The credential format is not fixed, and any equivalent primitive capable of carrying the governance-chain attestation is within scope.
Per-segment attestation is carried inline with the marker stored data. The specification describes the cryptographic integrity attestation field of a governed mesh message as typically sixty-four to one hundred twenty-eight bytes, carrying a signature over the preceding fields. The overhead is justified by the governance and regulatory properties it enables. Deployments requiring lower density may select among marker types and modalities, but the attestation is structural to the marker rather than an omittable annotation.
Alternative Embodiments
In a first alternative embodiment, the marker-track primitive admits a plurality of marker types, including passive energy-harvesting markers, semi-passive markers with small-battery-backed data response, active markers with dedicated power and continuous broadcast, hybrid markers with governance-policy-configurable active and passive response modes, multi-modal markers providing response through multiple physical channels producing redundant authentication, embedded-infrastructure markers, mobile-deployed markers, ephemeral markers with governance-policy-defined time-to-live, and composite markers combining two or more of the foregoing.
In a second alternative embodiment, marker interrogation admits a plurality of modalities, including radio-frequency interrogation, optical interrogation, acoustic interrogation, magnetic interrogation, electric-field interrogation, and any governance-policy-defined future modality. Multi-modal interrogation produces redundant marker-read observations combinable through cross-medium composite detection, supporting robustness to single-modality disruption, with a cross-modality marker-consistency evaluator verifying consistency across multi-modal marker responses where multi-modal markers are deployed.
In a third alternative embodiment, the track topology encoded in the marker sequence admits a plurality of topology categories beyond linear-segment markers, including switch-point markers, junction markers, yard markers, regulatory-zone entry and exit markers, platooning-zone markers, loading-zone markers, intermodal-transfer markers, emergency-egress markers, station markers, and bus-stop markers, with composite markers combining two or more encoding categories.
In a fourth alternative embodiment, a reputation-weighted marker-read admission evaluator weights marker reads by the marker's track record, and a marker-revision evaluator verifies that the marker's revision version is the most recent admitted version, so that superseded or low-reputation marker reads can be down-weighted or rejected at admission.
In a fifth alternative embodiment, route segments are credentialed across multiple authorities through cross-authority composition, including sequential-authority composition with transitions at credentialed authority-boundary markers, joint-authority composition wherein segments are jointly credentialed by two or more authorities, delegated-authority composition, federated-authority composition with authority-mapping translation, and escalated-authority composition wherein a higher authority overrides sub-authority credentials for specified route types such as emergency response or regulatory inspection.
Composition with Other Primitives
Per-segment attestation composes with the marker-read admissibility evaluator: admission verifies the cryptographic integrity attestation of each marker read, verifies the marker's authority credential against the governance chain, verifies marker-sequence and marker-position consistency, and verifies that the marker's temporal validity is consistent with mesh-derived time. Marker reads that are spoofed, injected, or otherwise inadmissible are rejected, and each rejection event, applied evaluator, and supporting evidence is recorded in a marker-rejection lineage record.
Per-segment attestation composes with the route-manifest constructor by supplying, for each segment, the authority credential against which a per-segment authority evaluator verifies the segment's authorization against the unit's operator class. Route manifests carry lineage linking the manifest to each contributing topology segment, each credentialing authority, and the governance-policy version applied to manifest construction, and route-manifest consumption at downstream operation is governance-chain-preserving with each consumption event recorded in lineage supporting post-hoc audit of route authorization decisions.
Per-segment attestation composes with the marker-track lineage recorder, which records each marker read, navigation determination, admissibility evaluation, coordination event, topology update, and fail-safe transition in the governance chain lineage field. Because authorization is carried at the segment, segment-governed parameters admit coordination across units and with infrastructure agents, and per-segment regulatory approval substitutes for per-unit sensor-stack approval in establishing that a unit's operation on a given segment was authorized.
Prior-Art Distinction
Prior autonomous-vehicle architectures operate through sensor-primary navigation producing path-by-inference routes without governance-credentialed attestation of authorized route, whereas the present primitive operates through governance-credentialed marker sequences as primary routing reference. The novelty here is not the use of cryptographic attestation but its placement at the segment granularity within a marker-track substrate, with each segment carrying its own authority-credentialed attestation of authorized transport-unit use.
Prior autonomous-vehicle services operate without regulator-reviewed per-segment approval, whereas the present primitive produces segment-by-segment governance-credentialed authorization admitting regulatory review prior to deployment. This makes the segment the unit of authorization, so that questions of authorized use and regulatory compliance can be answered for an individual segment rather than for an entire route or an entire vehicle stack.
Prior architectures do not support cross-authority route composition spanning multiple jurisdictional authorities, whereas the present primitive composes segments credentialed by different authorities subject to governance-policy-defined cross-authority compatibility. Per-segment attestation is what makes such composition governance-chain-preserving, because each composed segment carries the credential and lineage by which its contributing authority can be reconstructed.
Disclosure Scope
This disclosure covers the carriage of an authority-credentialed attestation by the governance-credentialed markers encoding each segment of a marker-track substrate, with the marker carrying among its attributes a marker identifier, an authority credential of the authorizing freight-track, transit, or transport authority, a governance-policy-defined topology payload, a marker-precision characterization, a temporal-validity specification, a cryptographic integrity attestation, a revision-version indicator, and a marker-lineage reference.
The disclosure encompasses the marker-read admissibility evaluation against the governance chain, the per-segment governance specifying permitted vehicle classes and operational parameters, the topology-update and governance-approval mechanism committing revisions with cryptographic revision-version attestation, the route-manifest construction and cross-authority composition that compose per-segment credentials, and the marker-track lineage recording by which authorization can be reconstructed. The cryptographic attestation may be produced under a digital-signature algorithm, a threshold-signature algorithm, a zero-knowledge attestation, a post-quantum attestation, or any equivalent mechanism supporting the governance-chain properties.
The disclosure is intended to read on any embodiment in which marker-track segments carry their own authority-credentialed attestation sufficient to support segment-by-segment governance-credentialed authorization, regardless of the specific cryptographic primitive, the marker type, the interrogation modality, or the structure of the surrounding marker-track substrate. The disclosure applies across freight, passenger, personal, transit, delivery, ride-sharing, and emergency operator classes, treating the distinction among them as a governance-policy configuration choice rather than a different underlying architecture. This disclosure is described in U.S. Provisional Application No. 64/049,409.
