substrate skillA

substrate is agent-read markdown (skill) from sparq-org/sparq: The opt-in shared zero-overhead evaluation substrate for the sparq engine and the reasoners — id-tuple row/key/posting vocabulary (`rows`), the XSD numeric value tower (`numeric`), the four id-tuple join kernels (`join`), and the SPARQL term total order (`compare`). All features are DEFAULT-OFF; opt in to exactly the slice you need. Use this crate when wiring a new reasoner that shares joins or numeric evaluation with the engine, or when working on the sparq-substrate crate itself. [SONNET-4.6] .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/substrate@git:20260726.6e8ef08
Exact content
mdr add sparq-org/sparq/substrate@sha256:60f1bd7c293032f9

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
