MAJORITY of TRAIN occurrences. (The weaker "covers every occurrence" form was +//! implied by the type-count assertion and is replaced — see the fix note at the +//! assert site.) +//! - **T3 TRANSFER** — of TRAIN's top-10 idioms, how many also occur (at all) in TEST, +//! plus the Spearman rank correlation of occurrence counts among the shared idioms. +//! **Asserts total top-K survival — the MEASURED fact.** The PARTIAL-survival +//! pre-registration it replaces was refuted and is recorded in § above, not removed. +//! - **T4 DRIFT** — the trigram TYPES present in TRAIN and absent from TEST (removed by +//! optimization) vs the types present in both (survived). Both sides must be +//! non-empty on this corpus (can-fire / can-stay-silent). +//! - **T5 OP DENSITY** — ops-per-function must be strictly lower in TEST than TRAIN +//!

(the only section carrying `reason` directly).
