This record contains the full publication package for Layer 3 of the Structural Invariant Framework (SIF 1. 0): a controlled multi-phase probe experiment using Corpus D — a 60-pair diagnostic instrument evaluated against three LoRA-adapted variants of Helsinki-NLP/opus-mt-en-uk (Conservative, ST-CANON, ST-STRONG) across canonical seeds 42, 123, 456. The central empirical finding is a precisely characterized encoder-to-decoder transfer limit: at the representation layer, the first-order split (ST-CANON > Conservative) holds in 99. 2% of cases across all seeds, establishing a stable structural signal. The second-order split (ST-STRONG > ST-CANON) holds at chance level (49. 2%), establishing a two-tier rather than three-tier representation hierarchy. At the output layer, no stable regime differentiation is observed across any seed or structural indicator — a null result treated as the primary positive finding, precisely characterizing where the current system's diagnostic reach ends.

Key empirical results: · First-order split (ST-CANON > Conservative): 250/252 = 99. 2%, robust across seeds 42, 123, 456 · Second-order split (ST-STRONG > ST-CANON): 124/252 = 49. 2%, indistinguishable from chance (All counts reported at text-level, N=252 units derived from the 30-pair Phase III evaluation subset. ) · Plurality (% strict ordering): INTERNAL 18. 3%, CROSS 6. 7%, RING 13. 3%, MULTIAXIAL 10. 0% · Output layer bridge threshold: NOT MET (max 1/8 cases, any seed) ·TRIZModule5Pilot: 5 cases, NORMAL trigger state, differentiated admissibility across contradiction classes Scope: All results are strictly bounded to the fixed low-data protocol — Helsinki-NLP/opus-mt-en-uk, LoRA rank 8, EN→UA, Corpus D (60 pairs), seeds 42, 123, 456. No generalization to other base models, language pairs, or corpus sizes is claimed.
