//! ONT-001 ontology gates (ONT-6 onward).
//!
//! - [`arming`] — which gates enter a repo's meet (`armed_gates` in `contracts/lint-baseline.json`, monotone; §3.9).
//! - [`capability_cells`] — ONT-4c5: every required ladder cell is Pass or Fail at the current release; NotRun is RED.
//! - [`extract`] — extractors: each entity type becomes RDF (§3.7; ONT-4b implements `pv_contract`).
//! - [`owl`] — Σ as OWL 2 EL functional syntax, in-house, and its told-closure TBox, advisory (§3.8; ONT-2c).
//! - [`rdf`] — the deterministic graph and its N-Triples writer (R-15; no blank nodes).
//! - [`shapes`] — the in-house SHACL-Core-subset validator and the Turtle export (§3.6; ONT-4b).
//! - [`sigma`] — Σ, the ontology's own declaration (`contracts/ontology.yaml`; §4.1).
//! - [`verdict`] — the one verdict lattice every `pv lint` gate reports into (§3.4).
//! - [`witness`] — ONT-5: the Horn graph pv-sat reasons over, the witness it writes, and the checker (F-7: no reasoner).
// ONT-9: the bounded universe KANI-ONT-9-1 quantifies over, and its relation-semantics oracle (test + kani only).
// ONT-9: planted-solution generation for `ont_planted` (F-12).
