Mechanism

The governed mesh message is the unit of transmission in the governed mesh protocol, and each message comprises a sequence of structural fields. The fields comprise, at minimum, a protocol-version field identifying the version of the governed mesh protocol used to construct the message; a message-type field identifying the category of payload; an authority-credential field encoding the authority credential of the transmitting device; a dynamic-device-hash field encoding a dynamic device hash of the transmitting device for identity-continuity validation by a receiving device; a temporal-reference field encoding a time of observation or event origin; a spatial-reference field encoding a position of observation or event origin; a time-to-live field encoding a validity duration of the observation; a payload field encoding domain-specific observation content; a forward-error-correction-metadata field encoding parameters of the forward-error-correction mechanism; and a cryptographic-integrity-attestation field encoding an attestation over the foregoing fields that binds the message to the authority credential of the transmitting device. The message-type field accommodates the addition of future payload categories through governance-policy update without requiring modification of the message format.

The message-type field identifies a category of payload selected from a plurality of payload categories, including marker-encoded geometry data, sentinel-deviation observation, cognitive-infrastructure-agent coordination directive, operating-unit-reported observation, peer state broadcast, emergency-alert observation, governance-policy update, and credentialing observation, among others. The authority-credential field encodes the authority credential of the transmitting device and is consumed by the composite admissibility evaluator to determine evidential weight. The cryptographic-integrity-attestation field carries an attestation computed over the preceding fields, binding the message to the authority credential. As the message propagates, a hop-count field is incremented by each relaying device, and a hop-history field is extended by each relaying device to record the relaying device's identifier, authority credential, and dynamic device hash; each forwarding device appends its record without replacing the originating identity, producing a governance-chain-preserving relay record. The time-to-live field encodes a validity duration beyond which the observation is discarded, and is enforced at relaying and carrying devices.

Relaying separates the governance-evaluation concern from the payload-consumption concern. Each relaying device evaluates a received message through its own composite admissibility evaluator before rebroadcast, and a message not admissible at the relaying device is not rebroadcast. The relay decision draws on the structural governance fields, the authority-credential field, the dynamic-device-hash field, the hop-history field, and the time-to-live field, rather than on the domain-specific payload content. A receiving device that consumes the observation evaluates the same structural fields through its composite admissibility evaluator and then exposes the payload to the consuming subsystem. A receiving device may admit a message of one authority level and reject another, may decline to relay a message of an authority level above a policy-defined relay scope, and discards any message whose time-to-live has elapsed.

The format is medium-agnostic. The same structural fields operate over any signaling medium capable of carrying a governed observation, and the specific byte-level, bit-level, or symbol-level encoding of the structural fields is not a limitation of the format. The signaling media disclosed include radio-frequency transmission, including sub-gigahertz industrial-scientific-medical bands, 2.4 gigahertz, 5 gigahertz, 5.9 gigahertz dedicated-short-range communication, 6 gigahertz, 60 gigahertz, cellular bands including Long-Term-Evolution vehicle-to-everything and 5G new-radio sidelink, millimeter-wave, sub-terahertz, and terahertz bands; optical-wireless communication, including visible-light communication, light-fidelity, near-infrared free-space optical, ultraviolet non-line-of-sight, and laser-based free-space optical; acoustic transmission, including in-air audible, ultrasonic, infrasonic, underwater sonar, and structure-borne acoustic; magnetic-field coupling and near-field magnetic communication; electric-field coupling; quantum-communication channels; and wired transmission, including Ethernet, serial buses, fiber-optic, and power-line communication. The architectural primitives operate identically over any such signaling medium, the inventive architecture residing in the governance-chain semantics rather than in any signaling medium. Alternative encodings of the structural fields include fixed-length binary encoding, variable-length binary encoding with length prefixes, tag-length-value encoding, type-length-value encoding, Concise Binary Object Representation, Protocol Buffers, FlatBuffers, Cap'n Proto, Apache Avro, ASN.1 Distinguished Encoding Rules, JSON, or XML.

Operating Parameters

The message-type field identifies the payload category, and the available categories may be extended through governance-policy update without modification of the message format. The cryptographic-integrity-attestation field binds the message to the authority credential of the transmitting device, and the protocol primitives are disclosed as independent of any specific cryptographic primitive, so that the cryptographic algorithm selection is itself a deployment choice rather than a fixed element of the format. The multi-hop relay mechanism imposes a maximum-hop-count parameter specified by governance policy and enforced by each relaying device, such that a message whose hop-count field exceeds the parameter is not rebroadcast. The time-to-live field encodes a validity duration of the observation and is enforced at relaying and carrying devices, which discard a message whose time-to-live has elapsed.

The duplicate-suppression mechanism at each relaying device detects and suppresses rebroadcast of a message previously relayed within a duplicate-suppression window, using a deduplication identifier computed from the originating-device identifier and a message-sequence number, from a cryptographic hash of the message body, or from any equivalent mechanism. The duplicate-suppression window is governance-policy-configurable and accommodates both short-window deduplication for suppression of immediate echo and long-window deduplication for suppression of delayed rebroadcast through store-and-forward. The relay-authority validation mechanism verifies that the relaying device is authorized by governance policy to relay messages of the authority level encoded in the authority-credential field, so that a message of a first authority level is relayable only by devices credentialed at or above a policy-defined minimum authority level.

Admissibility decisions at a consuming device are evaluated through the composite admissibility evaluator, which takes into account the authority credential encoded in the message, the trust-slope continuity of the originating device's dynamic-device-hash history, the carrier and relay chain recorded in the hop-history field, and the time-to-live consumed in transit. The hop-history field supports trust-weighted evaluation, wherein a message that has traversed a plurality of high-authority relaying devices is assigned higher evidential weight than a message that has traversed low-authority or unverified relaying devices. The governance policy that defines these decisions is itself distributed through the governed mesh, by means of governance-policy-update messages carried as a message-type category within the same message format.

Alternative Embodiments

In one embodiment, the message format operates over radio-frequency signaling media, including Long-Term-Evolution vehicle-to-everything and 5G new-radio sidelink bands, for vehicle-to-vehicle and vehicle-to-infrastructure observation exchange. In another embodiment, the format carries marker-encoded geometry data read from a passive environmental marker, the marker-encoded observation carrying an authority-credential field that downstream readers consume through the composite admissibility evaluator. In a further embodiment, the format operates over optical-wireless signaling media, including visible-light communication and free-space optical communication, for credentialed observation exchange where a radio-frequency medium is unavailable or unsuitable.

Mobile store-and-forward provides a further embodiment in which an operating unit, a ground vehicle, an aerial platform, an unmanned aerial system deployed for the purpose of mobile carriage, a maritime vessel, or a personal communication device carried by an operator, accumulates governed mesh messages in a carrier buffer while connectivity is unavailable and re-emits them when connectivity to a second environmental device, a second operating unit, or an ingress point is restored. The authority credential, the originating dynamic device hash, and the hop history persist across the connectivity gap, and the time-to-live field determines whether the carried message is still admissible at re-emission. Each re-emitted message carries a carrier-lineage appendment recording the carrying operating unit's identifier, carriage interval, and authority credential in the hop-history field, rather than replacing the originating identity.

In a redundancy-sensitive embodiment, the forward-error-correction-metadata field carries the parameters of a rateless erasure code, including a source-symbol-count parameter, an encoded-symbol-index parameter, and a coding-scheme identifier, so that a receiving device reconstructs the source message from any subset of encoded symbols exceeding a reconstruction threshold, without session establishment, delivery confirmation, or retransmission negotiation. In a privacy-sensitive embodiment, the cryptographic attestation of the authority credential is produced under a zero-knowledge attestation rather than a conventional digital signature; the authority-credential format is disclosed as not limited to any specific cryptographic primitive, so that a digital-signature, threshold-signature, zero-knowledge, or post-quantum attestation may be substituted while preserving the governance-chain properties.

Composition

The message format composes with the other governed-mesh protocol primitives. The authority-credential field is supplied by the device credentialing lifecycle, which governs enrollment, rotation, and revocation of governance credentials; the dynamic-device-hash field is supplied by the continuity-based device identity mechanism; the hop-history field is appended by every conformant relaying device; the time-to-live is set by the originating authority's policy. The composite admissibility evaluation at a consuming device draws on each of these fields together with locally held governance policy. A message therefore traverses arbitrarily many signaling media and arbitrarily many vendor implementations while carrying with it the body of evidence needed for a downstream admissibility decision.

Composition with the forward-error-correction mechanism permits resilient propagation across lossy and intermittent links, with the forward-error-correction-metadata field carrying the parameters needed for receiver reconstruction from partial capture. Composition with the dynamic-device-hash continuity mechanism permits a receiving device to validate identity continuity of the emitting device through trust-slope continuity rather than through a static device identifier vulnerable to replay. Composition with the governance-policy propagation mechanism permits the set of payload categories and the admissibility policies themselves to evolve in the field, distributed through governance-policy-update messages carried within the same message format that carries operational traffic.

Prior-Art Distinction

The governed mesh message is structurally distinguished from prior sensor-telemetry message formats, prior vehicular-communication message formats, and prior Internet-of-Things message formats in several respects. First, it carries an authority-credential field as a structural element rather than as an optional extension, the field being consumed by the composite admissibility evaluator to determine evidential weight. Second, it carries a dynamic-device-hash field supporting continuity-based identity validation, rather than a static device identifier vulnerable to replay. Third, its spatial-reference and temporal-reference fields support multiple coordinate and time frames, including mesh-derived coordinate frames and mesh-derived time, rather than assuming a single global coordinate frame or time reference. Fourth, it carries a forward-error-correction-metadata field supporting partial-symbol reception, rather than assuming guaranteed-delivery or session-based transport.

Fifth, the cryptographic-integrity-attestation field binds the message to the authority credential, producing composite-admissibility-evaluable input to consuming agents rather than a simple valid-or-invalid authentication output. The protocol primitives are disclosed as independent of any specific physical-layer signaling technology and of any specific cryptographic primitive, so that the structural fields are preserved end-to-end and operate identically over any signaling medium capable of carrying a governed observation. Downstream consumers evaluate the same structural fields regardless of the path the message took to reach them, and the governance chain is intact on arrival regardless of how many signaling media were traversed.

Disclosure Scope

Operationally the message format provides a single structural surface for testing and field interoperation. A relay vendor demonstrates conformance by evaluating a message through its composite admissibility evaluator, appending a hop-history record, and rebroadcasting the message; an originating-unit vendor demonstrates conformance by emitting the structural fields correctly over a signaling medium; a receiving-unit vendor demonstrates conformance by applying its admissibility policy to the parsed structural fields. Conformance to the message format is therefore demonstrable independently of any one signaling medium, since the protocol primitives operate identically over any signaling medium capable of carrying a governed observation. Field interoperability between vendors is a property of the format itself.
