TEPP

TEPP is the Temporal Event Psychometrics Platform: a multilingual, temporal, relational measurement system whose statistical and psychometric arithmetic is implemented in Rust.

Current implementation state

This branch keeps the Rust workspace quality foundation and the bounded foundation crates. Domain crates expose only tested contracts: immutable evidence, six-clock temporal values, event mentions/instances, relations, membership, persistence, splits, simulation, validation, API DTOs, and the predicted-versus-observed promotion gate. This branch establishes the Rust workspace, quality-gate foundation, and the longitudinal within/between decomposition capability. The eleven bounded crates compile independently. longitudinal_core exposes within/between decomposition and component RMSE APIs; the remaining crates expose no placeholder production APIs, and domain behavior for them begins in Task 2 with immutable evidence identifiers and source records. This branch establishes the Task 1 Rust workspace and quality-gate foundation. The twelve bounded crates compile independently but intentionally expose no The eleven bounded crates compile independently; Task 1 includes the implemented encrypted_mapping crate with AES-256-GCM sealing and purpose-bound opening, while the remaining domain behavior begins in Task 2 with immutable evidence identifiers and source records. The eleven bounded crates compile independently. derived_sensitivity inherits source Restricted/Internal classes onto topic, factor, and relation artifacts and fails closed on unknown kinds; derivation and blanket PII masking are not declassification. Other crates still begin domain behavior in Task 2 with immutable evidence identifiers and source records. The eleven bounded crates compile independently but intentionally expose no placeholder production APIs. Domain behavior begins in Task 2 with immutable evidence identifiers and source records.

Stable Rust line coverage is measured with cargo-llvm-cov. Branch coverage is measured in a separately pinned nightly lane because Rust branch coverage remains an unstable compiler capability. A zero denominator is reported explicitly for this skeleton-only slice; it must never conceal uncovered production behavior.
