Map TIPREDVAR through 2017-era summary.ctsemFit.R as solve(sqrt(diag(TIPREDVAR))) %&% TIPREDVAR after strictly positive v. OpenMx %&% is t(A)%*%B%*%A; the default ridge is 0; dimnames are TIpredNames. The scalar correlation is v/v = 1. Refuse unstandardised TIPREDVAR, MANIFESTVARstd, and addedTIPREDVAR. TIPREDVAR does not require a<0.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The restored standardization can produce a tiny floating-point deviation from the required exact value of 1.0 for some valid inputs. The PR is otherwise mergeable with explicit owner awareness and a follow-up to canonicalize the result and add the requested contract test. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 1826-1829: Update
recover_standardised_time_independent_predictor_variance to retain the existing
finite-value checks but return exactly 1.0 after they succeed, instead of
returning the computed scaled result; add a contract test asserting the
bit-level 1.0 result for input variance 3.0.

Union TIPREDVARstd (v/v) with disparate families on repaired main; add Errors docs, repair doc blanks and seams, dedupe imports. Gate evidence: branch 3796/3796, line 100%, Python 100%, workspace clippy -D warnings and contracts PASS.

Superseded by canonical-owner migration
Closed after verifying that the reusable static scalar-variance standardisation contract belongs to
ContextualWisdomLab/fast-mlsirm, not TEPP's legacypsychometric_coretechnical layer.The unique scientific/review evidence from this branch is preserved rather than discarded. In particular, the resolved review finding proving that direct IEEE-754 evaluation of
(1/sqrt(v))*v*(1/sqrt(v))can yield1.0000000000000002forv = 3has been promoted to the canonical owner path. fast-mlsirm PR #1723 has source-level RED lineage and an executable contract requiring exact binary641.0forv = 3,f64::MIN_POSITIVE,6.4, and1e300, plus fail-closed zero/negative/non-finite handling and a versioned Published Language identifier.TEPP PR #315 remains Draft only as the current named ctsem/TEPP adapter lineage. It must not land its duplicate local arithmetic. After the fast-mlsirm contract is merged and released/versioned, #315 or its consolidated Longitudinal Modeling successor must become an ACL/adapter over that released contract, verify parity with the preserved TEPP evidence, retain TEPP's clock/model-specific admission policy, and delete the duplicate production kernel.
This PR's immutable discussion and branch remain scientific lineage. Do not reopen or merge it independently.
Original target: restore Driver, Oud, and Voelkle (2017) scalar
TIPREDVARstdreporting semantics on TEPP. The model-specific naming/time policy remains TEPP-owned; reusable static arithmetic is now routed to fast-mlsirm.
