feat(analysis): bind two-group OLS invariance to an analysis-run profile#386seonghobae wants to merge 1 commit into
Conversation
Jointly invoke classify_two_group_ols_invariance and recover_strong_gated_latent_mean_difference as cutoff-safe two_group_ols_invariance_v1. Metric/configural status fails closed. Not MGCFA, not a sampler, not implemented-main.

Changes두 그룹 OLS 불변성 분석
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds a public two-group OLS analysis-run profile that can reject equivalent cutoff instants and accept artifact metadata whose excluded counts exceed the intended execution bound. It also relies on an outer caller to bind observations to authorized snapshot and tenant provenance and to record failed or replayed runs, creating bounded data-integrity and auditability risk; merge should wait for fixes or explicit owner acceptance.

🟡 Impossible evidence counts pass validation
An artifact accepts counts above MAX_EVIDENCE_UNITS and arbitrary excluded counts. Consumers can accept results that no bounded execution can produce.
Prompt for agents
Extend TwoGroupOlsInvarianceArtifact::validate in crates/analysis_engine/src/invariance_artifact.rs to enforce the execution profile's MAX_EVIDENCE_UNITS bound across both groups. Include eligible and excluded-after-cutoff counts, use checked addition, and reject any overflow or total that exceeds the profile limit. Add parser and serializer tests for oversized eligible counts, oversized excluded counts, and overflowing totals.

🔍 Equivalent cutoff timestamps are rejected
execute_two_group_ols_invariance_run requires canonical timestamp text, not equal instants. Valid RFC 3339 offsets fail unless callers normalize requests first.

🟨 Untrusted artifacts can forge invariance claims
A parsed strict artifact can contain unequal loadings, intercepts, residuals, or only two observations. Downstream consumers can trust a forged latent-mean license.

In `@crates/analysis_engine/src/invariance_artifact.rs`:
- Around line 169-191: The validate method must include both excluded
observation counts in the total evidence-unit limit: sum the four
reference/comparison eligible and excluded counts using checked_add, reject
arithmetic overflow, and reject totals exceeding MAX_EVIDENCE_UNITS. Ensure
from_json and to_json therefore reject oversized artifacts, and add a tampering
test covering valid eligible counts with excessively large excluded counts.
- Line 283: Update AnalysisRunRequest::validate to parse
request.knowledge_cutoff and compare the resulting instant with knowledge_cutoff
instead of comparing RFC 3339 strings, so equivalent offsets such as +00:00 and
Z validate identically. Continue storing the canonical UTC representation from
KnowledgeCutoff::to_rfc3339() in the artifact.
In `@crates/analysis_engine/tests/invariance_execution_contract.rs`:
- Around line 21-32: Extend the invariance execution-contract tests beyond the
exact `series` fixture with seeded synthetic observations containing known
intercept, loading, latent-mean difference, and residual noise. Add assertions
for parameter recovery and RMSE or bias bounds, and exercise both strong and
strict gates while preserving deterministic generation and existing noiseless
coverage.
In `@docs/adr/0039-two-group-ols-invariance-analysis-run.md`:
- Around line 84-89: Expand the acceptance criteria in the two-group OLS
invariance analysis ADR beyond fixed toy observations: define realistic
synthetic-truth checks for parameter recovery, RMSE, bias, interval coverage,
and invariance gating, and require exact-head test validation. Document why
temporal ordering and graph recovery do not apply to this profile; if parallel
CPU/GPU paths are introduced, also require numerical equivalence against the CPU
f64 reference.

Line 289의 실행기는 cutoff 전의 전체 입력을 MAX_EVIDENCE_UNITS로 제한합니다. 그러나 validate는 두 excluded count와 네 count의 합계를 검사하지 않습니다. 따라서 from_json과 to_json은 eligible count가 각각 2이고 excluded count가 매우 큰 artifact를 허용합니다. 네 count를 checked_add로 합산하고, overflow 또는 MAX_EVIDENCE_UNITS 초과를 거부하세요. 해당 tampering 테스트도 추가하세요.

cutoff 문자열 대신 cutoff instant를 비교하세요.
AnalysisRunRequest::validate는 RFC 3339 오프셋을 허용하고, KnowledgeCutoff::to_rfc3339()는 UTC 형식으로 정규화합니다. 따라서 동일한 instant라도 +00:00과 Z가 다르면 현재 비교가 InvalidEvidence를 반환할 수 있습니다. 요청 cutoff를 파싱한 뒤 instant를 비교하고, artifact에는 canonical 값을 사용하세요.
