Concept & directionLNK

Sections 1–3 define the open-world architecture. Sections 4–16 cover movement, control, utility, parts, configuration, lifecycle, measurements, domains, packs, implementation and invariants. Sections 17–24 deepen semantics, identity, mechanism, control, lifecycle, telemetry, vehicle-native agents and governance. Sections 25–44 define exact records, ledgers, runtime, schemas, math, telemetry, physics, safety, identity, markets, APIs and operations. Sections 45–54 add executable institutions, casework, title, insurance/repair, moderation, youth protection, management teams, tax, incident response and market integrity. Section 55 and Appendices N–Q define the v1.4 corrective profiles, migration, immutable release bundle and agent contract.

PartPurpose
1–3 SubstrateAdmission, durable identity, facets, type recipes, vocabulary governance
4 Movement physicsSupport, energy, conversion, force, interface, steering, stopping and stability
5 ControlHuman, remote, assisted, scripted, autonomous and mixed authority per function
6 UtilityWhat the machine can carry, sense, transform, manipulate, produce or serve
7–10 Whole machineSystems, parts, interfaces, configurations, modifications, service, tests and failures
11–12 Domains + typesMedium transitions, operating envelopes and a wide canonical recipe catalog
13–16 GovernanceStandards adapters, schema mechanics, difficult examples, invariants and rollout
17–20 Semantic depthKnowledge states, identity continuity, coordinates, rare mechanisms and control transitions
21–24 Implementation depthDigital thread, telemetry evidence, agents/markets, security and executable contracts
25–28 Canonical contractsWire primitives, claims/evidence, immutable configuration graphs and lifecycle transactions
29–32 Runtime + APIsTelemetry/media ingestion, ledger/replay/scale, governed action/market execution and conformance
33–36 Wire + computation substrateExact canonical bytes, digests, proofs, SQL append, registry evolution, units, frames, clocks and test equivalence
37–40 Runtime semanticsTelemetry protocol, physics/capability compiler, control leases/safety and grounded vehicle-agent runtime
41–44 Governed production systemIdentity/privacy, auctions/accounting, HTTP/events/SDKs, deployment, SLOs, replay and release engineering
Appendices84 official references, 50 edge recipes, 256 implementation fixtures, wire/state matrices and KUN plus cross-domain traces
Table
Three precision rules
Support is not propulsion. Propulsion is not useful action. A regulatory label is not the physical type of the machine. Keeping those distinctions prevents almost every category failure in a universal vehicle system.
v1.4 corrective release — record-core semantics remain stable while operational ordering, proof targets, confidential cursors, reboot-safe control, atomic external dispatch, executable institutions, migration, and release discovery become exact. See Section 55 and Appendices N–Q.
