evals/curriculum_loop_closure — Lane Contract

ADR: ADR-0104 Invariants:

  • curriculum_proposal_replay_equivalence
  • curriculum_proposal_single_review_path

Purpose

Prove that curriculum-authored teaching items can emit :class:PackMutationProposal candidates that traverse the existing reviewed teaching path without violating ADR-0104 hard constraints.

The lane asserts:

  1. A legitimate PACK_MUTATION_CANDIDATE curriculum finding produces a curriculum-sourced proposal with source.kind="curriculum" and epistemic_status=SPECULATIVE.
  2. Identity-override curriculum items are rejected at construction, before review, so the proposal never reaches the proposal log.
  3. A finding whose replay-equivalence check fails is rejected at construction; its finding_id appears in the batch's rejections list with reason replay_equivalence_failed.
  4. A non-PACK_MUTATION_CANDIDATE finding raises :class:CurriculumProposalError; curriculum import cannot promote diagnostic findings into pack mutations.
  5. Same finding stream + same curriculum_id + same revision -> byte-identical proposal id stream across two runs.

Cases

  • positive_basic — single coherent PACK_MUTATION_CANDIDATE finding -> proposal emitted with curriculum source.
  • identity_override_subject — finding subject contains an identity-override pattern -> rejected at construction.
  • identity_override_action — finding proposed_action contains an identity-override pattern -> rejected at construction.
  • replay_equivalence_failed — finding sent through a checker that reports trace-hash divergence -> rejected at construction.
  • wrong_finding_kind — non-PACK_MUTATION_CANDIDATE finding -> raises CurriculumProposalError.
  • determinism — three findings emitted twice; proposal-id streams must be identical between the runs.

Determinism

The runner emits results/v1_dev.json with case results and a SHA-256 of the canonical report bytes. Two consecutive runs against the same fixtures must produce identical bytes.

Exit code

Non-zero on any divergence between expected and actual outcomes.
