/**
 * Phase-cut sidecar artifact (remediator auto-phasing, T3).
 *
 * The foundations→consumers phase cut derived by {@link derivePhaseCut} is a
 * DERIVED, deterministic artifact (a pure function of the finalized module
 * contracts' module-dependency DAG — producer/consumer `artifact:<name>` tokens
 * in `inputs`/`outputs`, unioned with any `neighbor_needs`). It is persisted as a
 * first-class sidecar —
 * `intake/contract/phase_cut.json` — so the cut the conceptual critique sees and
 * the cut the implementation-DAG promotion enforces are ONE source, inspectable
 * on disk, not two inline recomputations that could drift.
 *
 * It is deliberately NOT a member of `CP_ARTIFACT_NAMES`: that enum drives the
 * LLM-phase staleness DAG and the phase-progression completeness checks, where an
 * "absent" entry perturbs sequencing. The cut is re-derivable on demand from
 * `finalized_module_contracts`, so it carries no staleness envelope — it is simply
 * (re)written whenever its single upstream is available, and read by consumers.
