The kind of contract artifact. Determines which validation rules apply.

• Kernel (default): a mathematical kernel contract — the provability invariant applies (must have proof_obligations, falsification_tests, kani_harnesses).
• Registry: a data registry (lookup tables, enum definitions, config bounds) — exempt from provability, validated for metadata + entries.
• ModelFamily: architecture metadata (HuggingFace family descriptors, size variants, vendor) — exempt from provability, validated for metadata fields. Custom top-level fields are preserved but not enforced by the kernel schema.
• ModelFamilyVariant: a concrete size variant of a model family (e.g. Llama 370M sovereign). Freezes hyperparameters (vocab, hidden dim, layer count) and delta-dispatches invariants from the parent family. Exempt from provability.
• Tokenizer: a concrete tokenizer contract — vocab bounds, required special tokens, round-trip gate, normalization form. Exempt from provability (gates are byte-exact tests, not Kani harnesses).
• TrainingLoop: a training-loop contract — loss schedule, optimizer config, gradient-clipping policy, checkpoint cadence. Exempt from provability; validated for metadata + schedule fields.
• PretrainingCorpus: a pretraining-corpus contract — dataset source, license, total-bytes bound, shard layout. Exempt from provability.
• TrainingPreconditionGate: a hard precondition gate that must be satisfied before training starts (e.g. Chinchilla compute-optimal token/parameter ratio, GPU memory floor, dataset checksum). Exempt from provability; validated for metadata + gate-formula fields.
• CorpusAssembly: a multi-source corpus assembly pipeline contract — declares input shards, dedup strategy, license-merge policy, and output manifest. Exempt from provability.
• Pattern: a cross-cutting verification pattern (threading safety, async safety, compute parity) that applies across multiple kernels. Exempt from the kernel provability invariant but still validated for metadata and any proof/falsification data present.
• Schema: a generic reference/schema document — exempt from provability, validated only for metadata.id, metadata.version, metadata.description, and metadata.references.

BeatBenchmark

A head-to-head BEAT benchmark: a committed, CI-wired claim that aprender beats an incumbent (sklearn / PyTorch / Unsloth / Ollama) on a canonical task, with a pinned baseline that fails CI on regression. The measurement backbone for the four-pillar “replace AND beat” mission (PMAT-741).
