DIVERGE-GTI1: Generative Transaction Interpreter

Status: frozen after the PQI1 development failure and before GTI1 training or evaluation. PQI1 confirmation remains unopened.

1. Failure boundary and hypothesis

PQI1 fit all 100,000 counterfactually complete QUERY rows with both protected Shohin and exact imported SmolLM2-135M, yet both emitted the identical development assignments: 640/768, with one complete 0/128 renderer inversion. The shuffled-label control reached 128/768. A stronger pretrained residual therefore did not rescue a shallow pooled mention scorer.

GTI1 changes the computation boundary rather than the PQI1 layer, width, duration, seed, renderer, tokenizer, or threshold:

Preserve the pretrained decoder's causal language computation, adapt only low-rank projections in its final four blocks, and make the model emit one complete typed READ(alpha|beta) transaction autoregressively. Score whole transactions by conditional sequence likelihood; never classify pooled mention fields independently.

The transaction is model-owned but the existing source symbol table still supplies the two mention groups. GTI1 is a semantic-interface gate, not an open-domain reasoning or architectural-novelty claim.

2. Frozen data and model arms

All arms use the exact immutable RRG1 QUERY corpus: 100,000 rows, 50,000 complete role-order pairs, ten lexical families, two clause forms, and SHA-256 2d325c860e707307886f782350e7ec35ae8c23ae275260b0a937bbb738078c1c. The opened CCR1 board with SHA-256 299237068f436ba33a68487b5300fcd724f8c98bd8bfe6b1916a4ebc7541ebf7 is development-only. The already-generated PQI1 board with SHA-256 27f198680cc7bcd7e0203949fe4dee1658fc057fe75302b7e2d43d74321201b8 remains sealed until admission.

Matched arms are:

1. protected Shohin step-300k plus GTI1 LoRA;
2. exact imported SmolLM2-135M-Instruct plus GTI1 LoRA; and
3. the same SmolLM2 arm with one fixed shuffled transaction target per row.

Shohin and SmolLM2 share the same 576-wide, 30-layer, 9-head geometry. Each real arm installs rank-8, alpha-16 LoRA in every linear projection of the final four blocks. The embedding, LM head, first 26 blocks, normalization, and every non-LoRA tensor stay frozen and hash-checked.

3. Frozen transaction protocol and budget

Source names are replaced by anonymous alpha and beta mention identities using the same gold-independent runtime mention masks as PQI1. The fixed prompt is:

Read the instruction and emit exactly one typed transaction.
Instruction: {canonical query}
Transaction:

The only legal completions are READ(alpha) and READ(beta). The model is trained by causal LM loss only on completion tokens. Inference computes the complete conditional log likelihood of both legal transactions and commits to one argmax transaction; no tokenwise repair, beam, parser fallback, threshold, or answer/state signal exists.

Every arm receives one epoch, batch 128, seed 2026080641, AdamW betas (0.9, 0.95), weight decay 0.01, gradient clip 1.0, peak LR 1e-4, and cosine decay to zero. The shuffled control uses the same order, update count, and optimizer state geometry.

4. Development gate

Promotion is conjunctive:

• SmolLM2 QUERY at least 765/768;
• every mode at least 254/256 and every renderer at least 127/128;
• SmolLM2 exceeds protected Shohin by at least 32/768;
• shuffled SmolLM2 is at most 430/768;
• replacing semantic context by occurrence order loses at least 250;
• swapping alpha and beta in the source flips at least 765/768 transactions after mapping back;
• arbitrary entity renaming changes zero canonical prompts and predictions;
• all non-LoRA backbone tensors are bit-identical before and after training; and
• every emitted transaction is one of the two legal complete transactions.

Only that matched assessor may open the sealed PQI1 board. A miss closes GTI1 without prompt, completion vocabulary, rank, layer, duration, LR, seed, renderer, tokenizer, or data variants.

5. Confirmation and successor

Direct confirmation repeats the absolute semantic and causal floors. A pass authorizes one zero-retraining composition with protected TOL3 WORLD, protected NVE1 EVIDENCE, exact factorized execution, and the qualified GTI1 QUERY owner. Only a complete end-to-end composition pass may connect the already-qualified oracle PL1 plasticity mechanics to natural language. Neither a direct GTI1 pass nor a component composition authorizes continuation pretraining.

If SmolLM2 passes while Shohin fails, the result establishes a same-geometry pretraining capability floor and the qualified Smol owner becomes a teacher or scratch-training target. If every real arm fails, the isolated semantic-parser sequence is closed; the next system must learn transaction semantics inside a broader end-to-end natural task rather than add another token/span/pointer or renderer-local reader.

6. Result: closed negative

Immutable commit 4e3b6c5 ran matched one-H100 jobs 744544/744545/744546; assessor 744547 wrote its report and exited 1 on the frozen gate. All three arms completed exactly 782 updates. Training exactness is 99,291/100,000 for Shohin, 99,989/100,000 for SmolLM2, and 50,060/100,000 against shuffled supervision (49,486/100,000 against true roles). The shuffled arm therefore stays at chance while both real arms fit.

Transfer is negative:

Every miss is a complete 0/128 renderer block. Context scrub is exactly 384/768 with zero mean signed margin for every arm. Mention swapping is not equivariant, while entity-renaming prompts, predictions, and score tensors are bit-exact and every non-LoRA tensor remains unchanged. The system learned template-level transaction lookup rather than target/distractor meaning.

Development-result SHA-256 values are b81677ac3a26b55abb2151b3fb66860c2537ba8393504aedee15add7b71eaf96, 1c4b759e56f1c3902ba26874577dbf98369630d78c185bef244f05c2d0826002, and b06b874e0fe447b18a1b4d5e717656beb28e060b91ce7bcd560e970ce1f6498f. The matched assessment SHA-256 is 62176a6409700f89c185c888f8697badf8fda3037c2568b8f800f90a89edf231. Fail-closed confirmation job 744549 was canceled by dependency and the sealed board was never opened. GTI1 is closed without prompt, LoRA, layer, duration, seed, renderer, tokenizer, or data variants.
