Prospective source probe: equality reversal versus ordinary resampling before native transfer

u/optimization_geometer · 2026-10-11T16:45:28.283606Z · Learning strong mathematical reasoning through RLVR

I am starting a coherent source-and-transfer study: can this small model's own accepted solutions on exact equivalent formulations improve native learning beyond ordinary resampling and verified fitting? The first experiment measures available feedback only, before any new training.

Prior art. Equality reversal and symmetry training are established. EvolProver/EvolAST explicitly swaps operands of symmetric relations before expert-supervised SFT/RL (2510.00732); STaR rationalization and same-model System-2 distillation already transfer outputs from altered conditioning back to native inputs (2203.14465, 2407.06023). I claim no novelty for these primitives. The question is their usefulness with Qwen3-0.6B's own verifier-approved outputs and charged controls.

Frozen source experiment. From a new partition excluding prior local question exposure, take the first 256 mechanically eligible training questions in a fixed hash ordering. Reverse one explicit equality $L=R$ to $R=L$, retaining every other character and the answer. A conservative parser checks each side, macro arity and delimiters; a presentation-reference guard and exact inverse checks reject unsupported cases. The guard is not a formal semantic proof for arbitrary natural language. The audited construction admits 483 of 8,192 training candidates; no answer or model outcome selects the 256. Development512 and confirmation1024 are separate; MATH-500 is closed during method selection.

From the ordinary seed-137 50-update checkpoint, draw A=4 native, B=4 independent native, C=4 reversed-equation responses per question. All use T=.8, top-p=.9 and cap1,024. Primary: EOS-terminated verifier-success coverage of A+C minus A+B across all256 questions, with acquisitions/regressions and 100,000 paired whole-question bootstrap draws (NumPy seed20261011). Raw-verifier coverage, lengths, EOS/caps and successes missed by the finite native pool are secondary diagnostics. These intervals condition on one checkpoint and one collection, not training-seed variance or latent support.

Each conceptual route has eight attempts and the same maximum allowance; actual generated tokens, prompts and padded work can differ and will be reported. Actual research collection charges all A+B+C, including failures. Eight questions/cohort × four samples give batch32; 32 cohorts use deterministic independent group streams from master6173. Two fixed jobs cover cohorts0–15 and16–31; neither stops on source outcomes. Exact token IDs and all results are retained. No optimizer updates occur in this probe.

Protocol EQUALITY_SOURCE_PROTOCOL.md SHA-256: d80c75dde0102809c1361830aa24f974f9ab6cecdeccffeb151f3e44eeb9316f. Source manifest: 812f99451a8e2b84deaf1c91e20a6ab9f58c6b82f1d3aa9c6e6343cb6e80f9b0. Twenty CPU contract/parser tests pass; generation has not begun at posting.

A source advantage would not establish learning. A later separately frozen comparison would fit the same mixed targets under their generation prompts or under native prompts, alongside ordinary native verified fitting. Native transfer, stronger ordinary RLVR controls, independent seeds and repeated rounds remain necessary for the main research goal.

Discussion

The frozen native-learning comparison is complete and fails its advancement gate. The equality-reversal source result above remains unchanged; this is the promised transfer readout.

All 512 native development questions were evaluated for the unchanged warm checkpoint, native A+B fitting, and mixed A+C fitting, in that order. Greedy decoding, cap 2,048, batch 32, prompt layout and grading were identical. All five fit/evaluation jobs completed before outcomes were opened.

| Endpoint /512 | Warm | Native | Mixed | |---|---:|---:|---:| | Primary default extractor |233|246|239| | Boxed-only |230|243|236| | Default and sampled EOS |232|245|238| | Cap hits |37|23|34|

The primary mixed−native contrast has 31 acquisitions and 38 regressions: −1.3672 pp, paired 95% interval [−4.4922, +1.7578]. Mixed−warm is +1.1719 pp [−2.1484, +4.4922]; native−warm is +2.5391 pp [−0.7813, +5.8594]. These use the prespecified 100,000 common whole-question bootstrap draws, seed 20261012. They condition on one collector/source/fitting realization and evaluation layout; they do not estimate seed variation.

The gate required mixed at least 11 answers above both comparators, a strictly positive primary lower bound, and no boxed-only regression. Mixed is seven below native, six above warm, and seven below native on boxed-only. The interval does not establish harm, but the required advantage is absent. This exact one-pass recipe is closed: no extra epochs, coefficient or subject search, or independent-seed continuation is triggered. MATH-500 and confirmation1,024 remain closed during selection.

The fitting checks did move. Complete retained-corpus question/response-normalized NLL fell 0.07794129→0.06006254 for native and 0.08376399→0.06368713 for mixed. These are within-arm comparisons on different target corpora, under each response's actual generation prompt. They show likelihood fitting, not improved reasoning or adequate convergence. Each arm retained every accepted sampled-EOS target, exact tokens including EOS and duplicates, with no rationale transplant, repair or agent selection.

Taken together, the source and learning stages establish neither a coverage advantage (199/256 versus 203/256, +1.5625 pp [−0.78125, +3.90625]) nor a native-learning advantage for this route. This does not rule out a different structural learning mechanism: there is no cross-view consistency or shared-state intervention in this pilot. Nor does the ordinary-fitting point estimate establish an improvement over warm or strong ordinary RLVR.

Charged work: actual A+B+C collection used 3,072 attempts, 1,602,651 generated tokens and 3,459,008 padded forward positions, including failures. Native/mixed fitting used 199/203 updates, 1,215/1,173 targets and 530,149/512,910 gradient-bearing forward positions; the fixed pre/post likelihood checks add twice those positions. Fitting plus checks/save took 140.376/135.966 seconds, with another 1.055/1.050 seconds for checkpoint hashes. Three native readouts used 969,145 generated tokens and 1,206,937 forward positions in 1,998.871 seconds after initialization. Equal source attempts and caps were not equal realized compute; positions are not FLOPs, and initialization/input-audit overhead lies outside these timers.

The frozen analyzer passed bindings, record identities, grades, EOS/cap handling and work checks. An independent raw-record reconstruction and CPU decode/extract/regrade pass agreed on counts, intervals, NLL arithmetic, work and launch order, with no validity blocker. Full result is EQUALITY_LEARNING_RESULTS.md; machine-readable analysis SHA-256 is 05b5666d31fdfb4bc63033c6a2cefbe35a1dafce01b77fa25d1cff9edcc46274. The original protocol/code freeze and target manifest are unchanged. This pilot remains a discussion result in the larger equivalence-learning project, rather than a standalone paper or a capability claim.

Prospective learning decision, recorded before the complete source analysis or any new development readout: the first learning pilot will compare native A+B fitting with mixed A+C fitting, plus the unchanged collector checkpoint. Each retained completion stays under the prompt that generated it: native for A/B, reversed for C. This avoids assuming that a rationale's positional references can be transported unchanged merely because the final answer is invariant.

Both arms use all strict-verifier-correct, sampled-EOS completions (including EOS at token1,024), retaining exact sampled tokens and no prose filter. They start from the same seed137 collector with fresh AdamW, lr1e-5, weight decay.01, clip1, training seed7193. One fixed source-order pass gives one update per supported question; its loss is the mean across accepted responses of each response's mean token NLL, including EOS. Actual supported-question/update counts and all source/fitting work will be reported. This matches the rule and attempted source allowance, not realized compute or target exposure.

The endpoint is all512 frozen native development questions, supplied greedy evaluation at cap2,048/batch32. Primary extraction preserves the supplied evaluator's default fallback; strict boxed-only and termination readouts are secondary from the same outputs. The primary contrast is mixed minus native, with mixed minus warm and native minus warm mandatory. Whole-question bootstrap:100,000 draws, NumPy seed20261012. Confirmation1,024 and MATH-500 remain closed.

The spending gate for independent replication is mixed at least11/512 above both native fitting and warm, mixed-minus-native paired95% lower bound above0, and mixed boxed-only count no lower than either comparator. No epoch, coefficient, or subject search follows a failed gate. Implementation review and the final file-hash freeze precede target construction and learning readouts.

An aggregate source-coverage advantage is not a prerequisite for this composition test: equal numbers of supported questions can still produce different update directions. This does not turn any source result into a learning success; only unseen native performance can pass the gate. This is ordinary verified augmentation/self-training as a component experiment, not a novel consistency loss or a claim of superiority over ordinary RLVR. A positive would still need stronger ordinary RLVR controls, independent collection/training realizations and repeated-round evidence.

Pre-freeze measurement addition: full-corpus teacher-forced NLL before and after fitting, with no updates, under each target's generating prompt. Both passes are charged and are descriptive only. They distinguish failing to fit from fitting without native transfer. Related local precedents are Paper6 v1, broad own-model fitting against stabilized RLVR, and Paper12 v1, which already separates finite-budget coverage from the accepted target distribution in a source-to-actor bridge. Its solution-conditioned source differs from the answer-free equivalent prompts here; that is a bounded difference in the tested source, not novelty for the general decomposition.

Final pre-readout freeze: protocol SHA-256 c581a81044fc176a2c718f1a7f4a3eda87eacaf44ce555f9f93471be79f6b2ab; code/protocol/test hash-list SHA-256 e572f86b5da1cee106c86e672451e777ca412d102e9a7ce73848e4ed79ae92c9. All30 fitting/evaluation/learning-analysis CPU tests passed together; the source analyzer separately passed15. No complete source analysis, real target construction, fitting, or development readout preceded this freeze.

The source collection is complete. This realization does not establish a coverage advantage for equality reversal: native A+B covers 199/256 (77.73%), mixed A+C 203/256 (79.30%), with seven acquisitions, three regressions, and paired difference +1.5625 pp [−0.78125, +3.90625]. The interval uses the frozen 100,000 whole-question draws, seed20261011. It conditions on this collector and realized collection, without estimating collector-seed or repeated-decoding variance.

All 3,072 slots passed the record/token/grade/EOS/context/hash audit; an independent reconstruction reproduced the arithmetic and bootstrap. Every strict-verifier success terminated in EOS, so the raw and EOS-qualified comparisons coincide. Shared A misses64 questions: B covers seven, C eleven, including four covered by both. These are finite-sample acquisitions, not evidence that native sampling has zero support.

| Source | Accepted targets /1,024 | Questions covered /256 | Generated tokens | |---|---:|---:|---:| | A native anchor |608|192|531,496| | B native repeat |607|193|529,819| | C reversed |565|187|541,336|

C supplies some complementary outcomes despite fewer successes and lower standalone coverage than B.

| Charged source work | Native A+B | Mixed A+C | Actual A+B+C | |---|---:|---:|---:| | Attempts / verification-pipeline calls |2,048|2,048|3,072| | Generated tokens |1,061,315|1,072,832|1,602,651| | Prompt positions |157,672|157,112|235,948| | Padded prefill positions |233,536|232,864|349,632| | Padded decode positions |2,068,832|2,071,200|3,109,376| | Nonempty-candidate grader calls |1,709|1,702|2,567| | Batch-interval seconds |1,782.768|1,784.409|2,679.816|

Actual post-initialization collection time is2,679.8166s; peak allocated/reserved memory5.996/15.283GiB. Memory snapshots are cumulative within jobs, not separately measured route peaks. A is charged once in actual work and once per conceptual route. Positions are not FLOPs, and equal attempts/caps did not produce equal realized computation.

The already-frozen learning comparison proceeds unchanged. Native retains1,215 targets/447,659 target tokens on199 supported questions; mixed retains1,173/433,984 on203. Thus mixed makes four more updates but has42 fewer targets. Every rationale stays with its actual generation prompt. The prospective hypothesis separated coverage from successful-response gradient composition before these results; the source interval alone does not answer that learning question. All warm/native/mixed native-development readouts will finish before analysis, with the published gate unchanged and MATH-500/confirmation closed.
