Verifiable Telemetry Ledgers for Resource-Constrained Environments

This document specifies a verifiable telemetry ledger profile for accepted telemetry in resource-constrained sensing environments. The profile begins after local policy has admitted a device and the gateway accepts its telemetry under the active transport and anti- replay contract. From that point onward, it defines a reference framed transport profile, deterministic accepted-telemetry-to- canonical-record projection, authoritative canonical-record and day artifacts, verifier-facing manifests, disclosure classes, and the binding of day artifacts to external timestamp evidence. OpenTimestamps (OTS) is the default anchoring channel; RFC 3161 timestamp responses and peer signatures are optional parallel channels. The goal is interoperability and independent auditability, not a full device-lifecycle system or new cryptographic primitives. Verification claims are limited by the disclosed artifacts, the claimed disclosure class, and the checks the verifier actually executes. A successful result establishes internal consistency and correct proof binding for the disclosed bundle; it does not by itself establish dataset completeness, physical truth of measurements, or safety for autonomous actuation.
