  "status": "PROPOSED 2026-09-26 (D180.3, taken 2026-09-26; the interim of TPS 4.4.13 and 4.2.13 as staged for revision 6, provisional numbers); awaiting the supervisor's verification",
  "conforms_tps": "0.2.0 (v15), with D180.3's texts T-C3 and T-C4 as staged (tpm_d179_d180_d181_texts 0.1.0)",
  "module": "tpc_strike 0.2.0 (proposed; reads with tpc_zone 0.5.0's helpers, proposed, schema 0.5.0)",
  "note": "Every expectation is hand-derived from the rule and the zone wording. The fixtures are the spring with its forms (examples/spring_draft.json), the zone corpus's toy and the tests corpus's FIX fixture, and one-change variants of them; test fixtures, not physics under research. Where a case is reachable only before the final pass its note says so. Both residences MUST reproduce every expect. 0.1.1 (schema 0.5.0; D176.1, D177.1): every fixture LAW carries a ROLE chosen by its physics (N2 EOM(v), KIN EOM(x), FREE_Z EOM(z)); sr3_scope reads no ROLE, so no expectation changed, and every final-pass status a note states holds under schema 0.5.0. 0.1.2 (S33, 2026-09-26): a LAW restating the motion of a FIXed or REMOVEd DOF carries ROLE CONSTRAINT (FREE_Z under C_NOZ; N2 and KIN where v or x is FIXed); a variant whose constraints leave z free gives FREE_Z EOM(z). No expectation moves."
