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 establishes the Task 1 Rust workspace and quality-gate foundation. The ten 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.
