…file Operators can request the existing psychometric_core Enders–Tofighi CWC composition as longitudinal_cwc_v1. Rows unavailable at the request cutoff are excluded; the digest-bound tepp.longitudinal_cwc.v1 artifact records within, between, and contextual slopes and refuses causal promotion. Not a new ESEM/DSEM estimator, not a Driver p.16 std restore, and not persistence.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This PR adds a public longitudinal CWC result profile, but it can currently accept an internally inconsistent contextual slope and produce a valid-looking result with incorrect statistics. Independently supplied score rows also require explicit provenance enforcement to prevent cross-tenant or cross-snapshot misattribution, so merge should wait for these bounded correctness and trust-boundary risks to be addressed or explicitly accepted.

🟡 Equivalent cutoffs reject valid runs
When a request uses a non-UTC RFC 3339 offset, execute_longitudinal_cwc_run compares it with canonical UTC text. The valid run fails despite identical instants.

🟡 Tampered contextual effects pass validation
LongitudinalCwcArtifact::from_json accepts any finite contextual_effect, even when it differs from between_slope - within_slope. Consumers can trust a scientifically inconsistent artifact.

🟡 Impossible evidence counts pass validation
LongitudinalCwcArtifact::from_json accepts row and exclusion counts above the 100,000-row execution limit. An artifact can claim a dataset the executor could never process.

🔍 Causal refusal is non-enforcing
claim_causal_effect always returns an error, but _ discards it. Only the hard-coded status prevents causal output, so the advertised gate adds no protection.

🔍 Recovery evidence remains narrow
The tests use one four-row noiseless example. Repository rules require realistic synthetic recovery evidence, but this profile adds no noisy recovery, bias, RMSE, or failure-rate study.

contextual_effect와 slope 관계를 검증하십시오.
현재 검증은 세 값이 유한한지만 확인합니다. 예를 들어 within_slope = 0.5, between_slope = 2.0, contextual_effect = 0.0인 JSON은 수락되고 유효한 digest도 생성합니다. 이 artifact는 CWC contextual effect를 잘못 보고합니다.
contextual_effect == between_slope - within_slope를 요구하고, 이 관계만 변조한 artifact가 거부되는 테스트를 추가하십시오.

📝 Info: Artifact size remains structurally bounded
validate bounds every variable-length field, so valid serialized artifacts remain far below 256 KiB without the removed post-serialization check.
