/**
 * Semantic projection for contract-pipeline staleness (B3).
 *
 * The staleness DAG used to key every dependency on the upstream's RAW payload
 * content hash, so any byte change to an upstream — a reworded rationale, a
 * regenerated `created_at` stamp, a reordered list — re-staled the entire
 * downstream chain and forced a full (often LLM-driven) re-authoring of
 * artifacts whose load-bearing inputs had not actually changed. That is the
 * exact friction B3 names: "an edit to finalized_module_contracts re-stales
 * obligation_ledger → test_validator_plan → contract_assessment even when the
 * obligation set is unchanged."
 *
 * The fix is to make staleness content/semantics-aware: a dependency is recorded
 * and compared by the hash of its *semantic projection* — only the structure a
 * downstream actually consumes — not its raw bytes. A cosmetic upstream edit
 * projects to the same value, so downstreams stay fresh; a real change to the
 * load-bearing structure (a new module invariant, a changed interface) projects
 * differently and correctly re-stales.
 *
 * This mirrors audit-code's `normalizeForMetadataHash`
 * (`src/shared/artifactFreshness.ts`): strip non-semantic provenance fields
 * universally, then apply a per-artifact structural projection. The two
 * orchestrators stay in conceptual parity (semantic-projection staleness) while
 * each owns the projection table for its own artifact set.
