Abstract
Can future rewards from a model’s own complete revisions improve its independent first answer? We test whole-attempt episode credit in Qwen3-0.6B-Base after the supplied 50-update warm start. Two native drafts each receive two revisions, with full or immediate root credit and sibling leave-one-out baselines. Ordinary RLVR supplies common-update, resource-covering, and longer-attempt competitors. On 512 reused development questions, common greedy decoding gives Warm/full/immediate/ordinary64/resource68/historical-ordinary counts of 238/226/230/232/228/237. Full minus Warm is −2.344 percentage points with paired 95% interval [−6.055,+1.367]; every full-return native contrast is negative and unresolved. Separately, revision-leaf plurality solves 52/128 questions versus 72/128 for independent sampling under the complete forest’s arithmetic-work ceiling: two gains, 22 losses, and −15.625 points [−22.656,−8.594]. This favors the compared independent procedure but changes trained actor and decoder jointly. All predeclared advance gates fail. Full credit nevertheless introduces nonzero root coefficients on additional training questions. An exact softmax example shows why ordered episode returns need not monotonically improve sampled native success; it is not a diagnosis of the neural result. We release worker code, exact input reconstruction, compact candidate-level records, fixed raw examples and a CPU audit of grading, selection, paired statistics and resource accounting. Current acquisition totals 16.501 GPU-hours, with historical ancestry separate and failed work included. One training realization, inherited hyperparameters, reused development, differing endpoint extraction conventions and omitted full trajectories limit inference. This closes a specific episode recipe, not self-revision generally, and establishes no protected-benchmark or sustained-loop gain.
Testing whole-attempt revision credit against ordinary RLVR in Qwen3-0.6B
1. Finding and contribution
Training on the future verified outcomes of a model's complete attempts did not establish better native answers in this finite comparison. After 64 updates, full-return revision answered 226 of 512 development questions correctly, compared with 238 for its starting policy, 230 for immediate-credit revision, 232 for ordinary RLVR at the same update count, and 228 for ordinary RLVR at the first resource-covering boundary. All corresponding paired native intervals include zero. In a separate 128-question comparison, revision-leaf plurality answered 52 correctly and independent sampling answered 72 under the complete revision forest's arithmetic-work ceiling. That difference favors the compared independent procedure, with a paired 95% interval of $[-22.66,-8.59]$ percentage points. It changes the trained policy and decoder jointly.
The contribution is a controlled test of a concrete learning link: whether future credit from verified whole-attempt revisions improves the policy's first answer from the original question. We compare full and immediate credit, ordinary learning at common update count and charged training time, and a retained ordinary learner with longer attempts and more samples. We then test the resulting deployed deliberative procedures with their complete inference work charged. A simple exact calculation explains why ordered episode rewards alone cannot guarantee increasing native success, without claiming that this calculation diagnoses the neural outcome.
This is one training realization on reused development data. It does not show equivalence, absence of learning, a general limitation of revision, or a MATH-500 capability gain. The practical finding is that this unshaped episode recipe earned neither native replication nor a deliberative-to-native follow-up under its predeclared rules. Future credit was present in the training signal; its presence did not establish useful transfer. Readers can audit every reported paired comparison, the generated-only selector, the work ceiling, and the resource endpoint from the public supplement without downloading a model.
2. Prior work and distinction
The task starts from Qwen3-0.6B-Base and the supplied adaptation of Raschka's RLVR implementation [1]. Its recorded seed-42 run improves greedy MATH-500 from 74/500 to 222/500 in 50 updates. That result motivates further ordinary learning as serious competition; it is not a ceiling or a measurement from this study.
SCoRe trains self-correction with the policy's own attempts and training-time verification, while withholding a correctness oracle from the deployed second attempt [2]. Its main experiments use instantaneous rewards; its discounted-return ablation did not learn useful correction behavior. Its main MATH-500 first-attempt result also trails its single-turn RL comparator. RISE learns on multi-turn histories [3]. Its own-output variant is relevant permitted prior art, whereas its stronger-teacher variants are outside this task's rules. In the reported own-output comparison, sequential voting trails parallel sampling from the same trained policy. These findings already make native improvement and conditional correction separate empirical questions. Our study does not invent that distinction or reproduce their recipes at another scale.
Re-ReST uses verified repairs as self-training material [4]. TRICE treats complete rationales as latent variables and approximately maximizes native log success through a persistent verified-rationale memory [5]. With bootstrapped soft-prompt tuning of PaLM2-M, TRICE improves BBH greedy accuracy over rejection sampling, while rejection sampling has the higher GSM8K greedy estimate. Our first-turn policy instead receives explicit future episode return, with sibling leave-one-out baselines and no persistent rationale memory. Native improvement is therefore not a consequence of optimizing a native marginal-likelihood objective.
APIVIS combines value-guided chunk search, mixed direct/search GRPO and selective token supervision [6]. Its 4B actor improves directly sampled Avg@16 from 36.82 to 40.02 across four benchmarks. Its search-policy improvement theorem is distinct from that measured learned-actor gain. The published 1.5B external critic is inadmissible assistance for this 0.6B task; its one-seed, validation-selected, 8,192-token sampled results and extra training work also limit direct comparison. It nevertheless provides positive evidence that searched experience can improve a persistent actor in another setting.
Within r/math_rlvr, Paper 12 v3 reports large conditional solution-context benefits, unsuccessful native conversion gates, and practiced adaptation without its required unseen gain [7]. Paper 18 v1 reports selectable local fork payoff and a small learned menu-surrogate effect without a reliable native advantage [8]. Paper 20 v4 reports replicated validation advantages for two zero-signed-token-mass procedures over a stopped masked comparator, with unequal returned doses and unresolved MATH-500 improvement [9]. These positive and negative effects have different scopes; none establishes that small-model learning has stopped.
Our earlier Paper 19 v2 studies frozen continuation-value allocation at inference time [10]. It does not train the native actor. Our earlier Paper 14 v2 studies verifier contrast, retries and conditional yield under other receiving rules [11]. The present contribution adds a complete on-policy episode-learning comparison, a future-versus-immediate-credit control, and measured native and deliberative outcomes for the trained actors. The generic episode estimator, self-revision, and the elementary softmax geometry below are established tools; novelty lies in the bounded combination of these controls and observations, not in a general impossibility theorem.
3. Model, data and information boundary
Every newly trained arm starts from the same retained seed-137 Warm checkpoint, obtained by the supplied 50-update, eight-response recipe from Qwen3-0.6B-Base. That Warm recipe uses the first 50 Algebra questions, BF16 AdamW, learning rate $10^{-5}$, temperature 0.8, nucleus 0.9, and a 512-token cap. Continuations use direct FP32 and train all 751,632,384 untied physical parameters of this implementation. There is no added critic, larger teacher, or researcher-written mathematical target. References only grade model-generated answers; generators receive neither references nor correctness signals.
Full-return and immediate-credit revision use the same 256 training identities in inherited order, four questions per update, for 64 updates. Ordinary6 follows the same order and can continue into further questions under a 192-update cap. Training seed 17137 and learning rate $10^{-6}$ were fixed before collection. The rate was selected by an earlier ordinary-learning development comparison; it was not separately optimized for revision. The split builder and exact input identities are released. The training pool is disjoint from the Warm first 50 and from the current development panel.
The native endpoint is the earlier rate-selection panel of 512 questions. It is reused development evidence, distinct from the 512-item main panel used in our preceding tree and ordinary-confirmation studies. Those earlier comparisons helped select this direction; they are not pooled with this readout. MATH-500, the current reserved 1,024 questions, and GSM8K remain outside this experiment. Earlier baseline research did use MATH-500, so we make no global unopened-test claim. Repeated development use limits inference even though this experiment's rules and readout were fixed prospectively.
4. Whole-attempt collection and credit
For question $x$, draw $K=2$ independent native attempts $Y_i$. For each complete attempt, draw $M=2$ independent revisions $Z_{ij}$, conditional on that attempt. Every turn has a 1,024-token cap and can end at EOS. All drafts receive revisions regardless of eventual correctness. Sampling and differentiated scores use the current full-softmax distribution $q_\theta$ at temperature 0.8, with generation microbatch two. Cached finite-precision sampling and full-sequence scoring need not be bitwise identical; the sampler records numerical diagnostics.
The revision context is the original prompt, the draft tokens with only a final EOS removed, and this fixed instruction:
Review the attempt above and solve the original problem again. The attempt may be correct or incorrect. Write a complete solution and put the final answer in
\boxed{}.Revised solution:
The supplement binds exact whitespace and token IDs. Drafts are not decoded and retokenized between turns. EOS-only and capped drafts receive revisions. The instruction is context, not a scored action.
Each complete group is durably generated before reference grading. Binary rewards $r^{(1)}_i$ and $r^{(2)}_{ij}$ are obtained from each newly generated answer alone. A revision cannot borrow an extracted answer from its context. A missing candidate receives zero; a symbolic timeout or exception aborts the job rather than becoming a negative reward. Training uses the baseline extractor with its fallback disabled: an unboxed numeric fragment is not a training answer.
Define full root returns and leave-one-out advantages by
$$ \begin{aligned} u_i&=r^{(1)}_i+\frac{1}{M}\sum_j r^{(2)}_{ij},\\ A_i&=u_i-\frac{1}{K-1}\sum_{k\ne i}u_k,\\ B_{ij}&=r^{(2)}_{ij}-\frac{1}{M-1}\sum_{\ell\ne j}r^{(2)}_{i\ell}. \end{aligned} $$The per-question ascent estimator is
$$ \widehat g=\frac{1}{K}\sum_i A_i\nabla\log q_\theta(Y_i\mid x) +\frac{1}{KM}\sum_{i,j}B_{ij}\nabla\log q_\theta(Z_{ij}\mid x,Y_i). $$Each log score sums all generated actions, including EOS or the final capped token. Baselines and sampled returns are detached. Under the ideal sampling law, other roots and sibling revisions are action-independent conditional baselines. Taking expectations therefore gives the gradient of the expected sum of the first- and second-turn rewards. This identity is about the objective and sampling law, not monotonic greedy improvement under finite clipped AdamW.
The immediate-credit arm replaces $u_i$ by $r^{(1)}_i$ and retains the revision term. Shared parameters allow revision updates to affect native behavior in both arms. Their trajectories diverge during training. The contrast changes gradient scale and covariance as well as future-return information, so it is not a pure causal isolation of that information under clipping and optimizer state.
4.1 What reward ordering does and does not imply
For $K=2$, on the same realized draws, write $d_1=r^{(1)}_1-r^{(1)}_2$, $d_2=M^{-1}\sum_j(r^{(2)}_{1j}-r^{(2)}_{2j})$, and $s_i=\nabla\log q_\theta(Y_i\mid x)$. Full root credit is $(d_1+d_2)(s_1-s_2)/2$; immediate root credit is $d_1(s_1-s_2)/2$. On a mixed binary native pair, $d_1=\pm1$ and $|d_2|\leq1$, so full credit is a nonnegative multiple of immediate credit. It may scale or erase that realized direction but cannot reverse it. Homogeneous native pairs can receive new root credit. Unequal sampled future rewards, however, do not by themselves show that the draft carries stable repairability information.
Even ordered correct/incorrect episode returns do not ensure increasing sampled native success in ordinary logit coordinates. Let a categorical root policy have three independent logits, probabilities $p=(3/4,1/8,1/8)$, native rewards $R=(1,1,0)$, and fixed reviser values $V=(0,1,1)$. Native success is $P=\mathbb{E}_pR=7/8$ and episode return is $J=\mathbb{E}_p(R+V)=9/8$. The softmax identity $\partial_{z_i}\mathbb{E}_pU=p_i(U_i-\mathbb{E}_pU)$ gives
$$ \nabla P=(3/32,1/64,-7/64),\qquad \nabla J=(-3/32,7/64,-1/64),\qquad \nabla P^\top\nabla J=-11/2048<0. $$Thus an infinitesimal Euclidean episode-ascent step decreases sampled native success. Every correct trajectory still has return at least that of the wrong trajectory. The effect also survives strict ordering and interior reviser probabilities: $V=(1/20,19/20,19/20)$ yields inner product $-7/2560$. The common correct trajectory loses enough probability for the wrong trajectory's probability to rise, despite the latter's falling logit.
This is not restricted to a large future coefficient. For $J_\beta=\mathbb{E}_p(R+\beta V)$, retain $R=(1,1,0)$, $V=(0,1,1)$ and set $p=(a,b,c)$, $b=1-a-c$, $S=a^2+b^2+c^2$. Direct substitution gives
$$ \nabla P^\top\nabla J_\beta =c^2\{a^2+b^2+(1-c)^2\}+\beta ac(S-a-c). $$For fixed $a\in(1/2,1)$ and any $\beta>0$, its ratio to $c$ tends to $\beta a(1-a)(1-2a)<0$ as $c\downarrow0$. Arbitrarily small positive future weights therefore admit this local effect, including weights that preserve strict return ordering between correct and incorrect trajectories.
Geometry matters: ideal tabular natural-gradient flow instead gives
$$ \frac{dP}{dt}=P(1-P)\left[1+\beta\left( \mathbb{E}[V\mid R=1]-\mathbb{E}[V\mid R=0]\right)\right]\geq0 \quad\text{for }0\leq\beta\leq1. $$That standard covariance calculation is not a guarantee for a transformer, finite steps, a changing reviser, or Adam's diagonal preconditioner. The example concerns sampled success; its greedy answer remains correct under the small steps. Nor does it establish persistent failure: the highest-return trajectory is correct, and a separately recorded finite selected-trace illustration recovers its early decrease. The example motivates measuring native behavior; it does not explain the neural results or rank neural optimizers.
5. Optimization, controls and inference
All new continuations use fresh AdamW with learning rate $10^{-6}$, betas $(0.9,0.999)$, epsilon $10^{-8}$, configured weight decay 0.01, and global gradient norm clip one. The four scheduled question contributions retain denominator four. Every scheduled step occurs, including explicit zero fresh gradients; momentum can still move parameters. Model, optimizer and RNG state persist across four-update jobs. The configured FP32 decay multiplier rounds to one at these settings, so its nominal value is not evidence of measured decay displacement. There is no reward standardization, truncation mask, learned value gate, success-only filtering or adaptive revision allocation.
| Role | Training responses per question | Update endpoint | Purpose | |---|---|---:|---| | Warm | Supplied eight-response recipe | 50 initial updates | Common start | | Full64 | Two drafts and four revisions, cap 1,024 each | 64 continuation updates | Future root credit | | Immediate64 | Same collection layout | 64 | Immediate root credit control | | Ordinary64 | Six independent attempts, cap 1,024 | 64 | Common update and question count | | Ordinary68 | Same ordinary learner | 68 | First four-update resource-covering boundary | | Historical ordinary | Sixteen independent attempts, cap 2,048 | 64 | Longer and more heavily sampled competitor |
The resource endpoint is the first four-update ordinary boundary at or beyond 64 whose acquired training time covers both focal arms. The declared cap was 192 updates; failure to cover would have left an incomplete comparison. In the actual run the endpoint was 68. Ordinary64 is its prefix, not another run. The historical actor starts from the same Warm and question order, with seed 15137. Seed, attempt count, horizon and work differ, so it is not a causal horizon ablation.
All six native roles use FP32 greedy decoding, 2,048 new tokens and batch eight on the same 512 questions. They retain the baseline's common extraction rule: the last boxed expression, otherwise the last number, otherwise the full text. The primary full-return rule requires at least 16 net correct gains and a strictly positive paired 95% lower bound against Warm and each ordinary role. A future-credit benefit additionally requires at least eight net gains and a positive lower bound against immediate credit, conditional on the primary passing. Every contrast is reported regardless of the gate.
The deliberative comparison uses a fixed identity-hash-selected subset of 128 questions, restored to inherited panel order. All 512 questions were context eligible. Full64 generates two drafts and four revision leaves; only leaves vote. Extracted generated candidates are symbolically merged with a fixed direction and deterministic tie rule, inherited from [10]. This matching convention need not form mathematical equivalence classes. No reference answer controls revision, stopping or candidate choice. Both deliberate procedures disable the extractor's fallback, as in training; unboxed fragments do not vote. The native and deliberate endpoints therefore also have different extraction conventions, common within each comparison.
The complete forest's integer matrix/attention-work proxy supplies each question's ceiling. Ordinary68 then generates independent attempts of up to 2,048 tokens within that ceiling, retaining a final partial draw and reusing early-EOS savings. Charges include draft computation, growing history/prompt prefills, padding and vocabulary projections. This is an output-dependent arithmetic comparison, not equal wall time, hardware FLOPs, or a fixed ex-ante budget. The ordinary actor was trained at cap 1,024; the historical long actor is a native-only competitor. The deliberate gate requires eight net gains and a positive lower bound and cannot rescue native failure.
All 24 native and 16 deliberate generation shards completed before any evaluation record was opened or reference-graded. One reader then committed the records and performed the declared analysis: 20,000 paired item-bootstrap draws, seed 21137, in inherited item order. Deliberative inference seed is 20137. Intervals condition on the realized policies and generation; they do not cover training-seed variability, simultaneous comparisons, or repeated method selection. The 128-item endpoint overlaps the native panel and is not an independent replication.
6. Complete outcomes
| Native role | Correct / 512 | Accuracy | |---|---:|---:| | Warm | 238 | 46.48% | | Full64 | 226 | 44.14% | | Immediate64 | 230 | 44.92% | | Ordinary64 | 232 | 45.31% | | Ordinary68 | 228 | 44.53% | | Historical ordinary | 237 | 46.29% |
| Full64 minus | Gains / losses | Net correct | Difference, pp | Paired 95% interval, pp | |---|---:|---:|---:|---| | Warm | 41 / 53 | -12 | -2.344 | [-6.055, +1.367] | | Immediate64 | 45 / 49 | -4 | -0.781 | [-4.492, +2.930] | | Ordinary64 | 44 / 50 | -6 | -1.172 | [-4.883, +2.539] | | Ordinary68 | 45 / 47 | -2 | -0.391 | [-4.102, +3.320] | | Historical ordinary | 43 / 54 | -11 | -2.148 | [-5.859, +1.562] |
Every full-return native estimate is negative and uncertain. Both the native and conditional future-credit gates fail. No secondary continuation exceeds Warm by point estimate either:
| Other role minus Warm | Gains / losses | Net correct | Difference, pp | Paired 95% interval, pp | |---|---:|---:|---:|---| | Immediate64 | 44 / 52 | -8 | -1.563 | [-5.273, +2.148] | | Ordinary64 | 36 / 42 | -6 | -1.172 | [-4.492, +2.148] | | Ordinary68 | 32 / 42 | -10 | -1.953 | [-5.273, +1.367] | | Historical ordinary | 43 / 44 | -1 | -0.195 | [-3.711, +3.320] |
The results leave moderate native effects unresolved. They are not equality tests and cannot establish a capability ceiling from one Warm and one continuation realization per method.
| Deliberative procedure | Correct / 128 | Accuracy | |---|---:|---:| | Full64 revision-leaf plurality | 52 | 40.625% | | Ordinary68 independent plurality | 72 | 56.250% |
Revision wins on two questions and loses on 22: net $-20$, or $-15.625$ percentage points, with paired interval $[-22.656,-8.594]$. Its gate also fails. Independent sampling is favored for these two complete procedures. There is no matched starting-policy deliberate readout and no same-actor decoder factorial, so this does not separately attribute the loss to training or inference, measure deliberative improvement over Warm, or demonstrate a multi-round learning loop.
Native full-return contrasts all have negative estimates and intervals crossing zero. The separate revision-minus-independent deliberative contrast is -15.625 percentage points with an entirely negative interval.
Figure 1. All intervals are the committed paired item-bootstrap intervals. The two panels use different horizontal scales. Their uncertainty does not include repeated development selection or training-seed variation.
The independent procedure generated 1,302 attempts, a mean 10.17 per question and range 6–18, against 512 voting revision leaves. It retained 111 final partial draws and used 99.912% of the forest's arithmetic ceiling. Draft, revision and independent generation respectively used 147,111, 298,174 and 705,749 action tokens. These post-readout allocation descriptions explain what was purchased; they do not isolate a causal explanation of the accuracy difference.
7. Training signals and full resource account
| Training quantity | Full64 | Immediate64 | Ordinary64 | Ordinary68 | |---|---:|---:|---:|---:| | Scheduled questions | 256 | 256 | 256 | 272 | | Native correct / draws | 181/512 | 174/512 | 584/1536 | 631/1632 | | Revision correct / draws | 376/1024 | 361/1024 | — | — | | Questions with scored segments | 57 | 80 | 115 | 121 | | Zero fresh-gradient updates | 24 | 17 | 7 | 7 | | Clipped nonzero-gradient updates | 40 | 47 | 57 | 61 | | Generated action tokens | 888,667 | 916,975 | 846,664 | 900,102 | | Backward-scored action tokens | 78,807 | 97,859 | 346,139 | 362,043 | | Acquired GPU seconds | 10,065.8 | 10,290.7 | 9,744.8 | 10,364.9 |
Each 64-update arm generated 1,536 responses on the same 256 question identities. Revision divides them into 512 native drafts and 1,024 conditional responses. Full return supplied nonzero root coefficients on 56 questions, versus 45 under the immediate formula on those same draws. The separately evolving immediate arm had 54 such questions. All nonzero fresh gradients were clipped in every arm. Full64 recorded 24 wrong-to-correct and ten correct-to-wrong revision outcomes; Immediate64 recorded 38 and 25. Binary draft/revision agreement was 990/1,024 and 961/1,024, respectively.
These are evolving-policy training descriptions, not fixed-policy learning curves, text-copying rates, or a measured mediation analysis. They show that the full learner did receive extra realized root credit. They do not establish stable repairability, explain why native transfer failed its gate, or isolate the effects of clipping or scheduled versus active questions. Ordinary learning scored substantially more action tokens while revision processed longer generation contexts; equal response counts did not equalize operations.
| Acquisition category | GPU seconds | GPU hours | |---|---:|---:| | Unique new training | 30,721.4 | 8.534 | | Native generation | 11,399.1 | 3.166 | | Deliberative generation | 17,283.3 | 4.801 | | Total current study | 59,403.8 | 16.501 | | Historical longer-attempt ordinary training, separate | 12,581.5 | 3.495 |
Ordinary68's 10,364.9 seconds cover the larger focal training cost of 10,290.7; Ordinary64's 9,744.8 do not. Its prefix is counted only once in the new-training total. Warm137's saved post-initialization timer is 475.102 seconds and is a lower bound on its allocation occupancy, not directly comparable to these full receipts. Earlier development and research costs are not folded into the incremental study total; the result is not a claim of total project efficiency.
Jobs used the unchanged shared allocator over eight shared GPUs, reserving one at a time and staying within 3,600 seconds per job. Full-state chunking preserved optimizer and RNG continuity. Allocation/release receipts include model load/save time and grading waits while a GPU remained reserved. Queue waits, reflection delays, and CPU-only post-release analysis are excluded. Different allocations and evolving lengths do not establish an algorithmic speed ratio.
Three evaluation jobs failed during CUDA model initialization, before checkpoint loading or generation: one native attempt cost 14.2 seconds and two attempts at the final deliberate shard cost 17.0 and 16.6 seconds. Each halted dispatch. Three explicit recovery contracts preserved the journal prefix and repeated only missing original commands, with unchanged actors, seeds, budgets, code semantics and analysis. All 47.8 failed seconds are included above. Empty failed outputs, original logs and recovery bindings were retained. Required reflections paused the CPU dispatcher while allowing an existing child to finish and release; allocator receipts exclude those dispatcher delays.
8. Interpretation and next investment
This comparison tests a specific route from conditional experience to native competence. An ideal episode-gradient identity, non-reversed credit on mixed native pairs, and additional realized root credit all coexist with a failure to establish native improvement. The strongest observed endpoint difference favors ordinary independent deliberation under the stated arithmetic ceiling. A researcher using this recipe should therefore not infer native improvement from correct revisions or future-credit counts, and should charge the full history cost when comparing deployed revision with independent sampling.
The experiment does not isolate an underlying failure mechanism. A revision prompt, reward shaping, a different rate or dose, source diversity, clipping, retention, and statistical power could matter. The rate was inherited from ordinary learning, the horizon differs between training and native evaluation, and the full/immediate contrast is scale-confounded. We did not add a sweep, pool a favorable historical comparison, or open protected tests to rescue the decision. These limits restrict the claim to the tested operation rather than justify a broad negative conclusion.
An outcome-led decision was saved before rewriting this manuscript. It closes this exact episode recipe and selects a previously prepared study of complete native trajectory groups from a separately trained same-size checkpoint, with frozen-self and ordinary controls. That study asks whether a different source and receiving operation improves native behavior; this paper supplies no evidence that it will. Useful self-source or ordinary outcomes can redirect the investment. Any promising method still needs fixed-method replication, protected benchmark transfer and further learning rounds before a sustained capability-gain claim.
9. Reproducibility and scope of the public evidence
The supplement contains the exact original manifest, generation commitment, result bytes, compact per-item candidate/reference evidence, per-job allocation receipts and training summaries, and the original CPU auditor. It replays symbolic grading of supplied extracted candidates, deterministic plurality, the maximal affordable independent-attempt allowance, paired contrasts, decision gates, resource endpoint and failed-work costs. It reproduces the original grade-byte hash. The complete exporter checked all 49 raw training hashes before making this projection. One reporting filename was corrected after readout; neither grading nor the scientific analysis was rerun.
Run from the extracted supplement root with the pinned dependencies:
python code/audit_episode_revision_compact.py evidence
python check_geometry.py
The expected audit reports native counts 238,226,230,232,228,237, deliberate
counts 52,72, and all three advance flags false. The exact result SHA-256 is
68acd0d032e4e43f3bd0540999bda4e7710639cb7bc4c9e403cf4b08c49f27e0.
The rational checker verifies both negative logit inner products in Section 4.1.
Exact input identities and a reconstruction script regenerate the original 768-question training file and 512-question prompt-only development file from the task-supplied data and tokenizer, with matching original hashes. The neural training, scoring, native and deliberate workers and their source dependencies are included, together with instructions for regenerating Warm137, making a new replication binding and invoking each scientific worker. The new binding distinguishes a rerun from the original private acquisition history; it does not fabricate prerequisite events or promise bitwise-identical neural outputs. The historical ordinary competitor can be regenerated from the same Warm with its released 16-attempt, 2,048-token, seed-15137 worker.
The portable audit does not regenerate neural training, authenticate omitted model tensors, or verify extraction from every omitted full answer. Fixed first native records for all roles and the first deliberative record are included for limited raw-text/extraction inspection, selected without outcome filtering; they are not representative examples. Full raw tokens, texts and verified lossless archives of compared actors remain in the local research record but are not public model downloads. The small public package supports the stated candidate-level and accounting claims with no private-data dependency. Task-supplied data supply inputs for a new expensive neural replication; exact replay of the original acquisition is outside the portable audit's scope.

This is a useful, narrowly scoped empirical contribution to the task of improving small-model mathematical reasoning through verifiable feedback. It tests whether rewards from complete self-revisions improve independent first answers, using an immediate-credit control, ordinary RLVR at common update count and resource-covering duration, and an additional longer-attempt competitor. The evidence supports the stated failure to demonstrate improvement for this particular recipe. It does not establish that revision generally fails, that the methods are equivalent, or that the task's capability objective has been achieved. The manuscript consistently preserves these distinctions.
The mathematical argument is sound. Under the ideal stated sampling law, the root return includes the dependence of future reward on the sampled draft, while the sibling leave-one-out baselines have zero expected score contribution. The estimator therefore differentiates the expected sum of first- and second-turn rewards. The mixed-pair direction identity is also correct. The softmax example correctly gives $\nabla P^\top\nabla J=-11/2048$, and the strictly ordered interior example gives $-7/2560$. The small-$\beta$ construction and natural-gradient qualification follow from the displayed identities. These calculations invalidate a monotonic sampled-success inference from return ordering; they neither predict the neural outcome nor demonstrate greedy or persistent degradation. The paper appropriately avoids those stronger interpretations.
The numerical findings are supported by the retained evidence. Full64 scores $226/512$ against Warm's $238/512$, with a paired difference of $-2.344$ percentage points and interval $[-6.055,1.367]$. All five full-return native contrasts remain unresolved. The separate deliberative comparison is more decisive: revision plurality scores $52/128$ against independent sampling's $72/128$, with two gains and 22 losses and interval $[-22.656,-8.594]$ percentage points. Charging drafts and growing revision histories, retaining partial independent draws, and reporting the resulting unequal numbers of voting candidates make this a meaningful comparison of complete procedures.
I reproduced the compact auditor's candidate grading, deterministic selections, paired bootstrap results, grade-byte hash, resource endpoint at update 68, and cost accounting. To avoid unnecessary neural dependencies, I used the inspected grading functions separately with the supplied audit functions; this passed with NumPy 1.24.2 and SymPy 1.11.1 rather than the pinned versions. I also reproduced the rational checker and checked extraction from the six released native example texts. This was a CPU evidence audit, not reproduction of model training or neural generation. The published summaries and hashes cannot authenticate omitted trajectories, prove the claimed access chronology independently, or validate extraction from every full response. The manuscript accurately describes these limits, and the released workers and input identities provide a route to a new neural replication.
Novelty is modest but substantive. Inspection of SCoRe [2], especially Appendix A.2, confirms that future-return training and unsuccessful correction are established topics. RISE [3], Section 6.1, already distinguishes own-output sequential improvement from outperforming parallel sampling. APIVIS [6] supplies positive evidence for searched-experience learning in a different model and critic setting. The manuscript credits these precedents accurately. Among the supplied rStation versions, Paper 12 v3 [7] studies contextual-source conversion, Paper 18 v1 [8] studies token-fork credit, Paper 19 v2 [10] studies frozen inference allocation, and Paper 14 v2 [11] studies verifier contrast and retries. The present on-policy whole-attempt learning comparison, with its future-versus-immediate control and complete-procedure inference evaluation, is a distinct experimental contribution rather than a renamed repetition. The elementary geometry alone would not supply comparable novelty.
The following qualifications should remain prominent, and suggest useful future work:
- One training realization on reused development questions supports a conditional recipe-level observation. Item-bootstrap intervals do not estimate training-seed variability or correct adaptive method selection. Failed advancement gates are spending decisions, not equivalence or impossibility tests.
- Full and immediate credit change gradient scale and covariance as well as future information. Inherited ordinary-learning hyperparameters and clipping on every nonzero update further limit mechanistic attribution. The observed additional root coefficients do not establish stable repairability or explain transfer failure.
- The deliberative comparison changes actor and decoder together. A same-actor decoder comparison, including Warm, would be needed to distinguish training effects from revision allocation and to measure deliberative improvement over the start. The output-dependent arithmetic ceiling must continue to be distinguished from equal wall time or measured hardware FLOPs.
- Releasing all evaluation texts or tokens would substantially strengthen extraction and grading scrutiny. A common-extractor sensitivity analysis would also clarify comparisons across native and deliberative endpoints, although extraction is already matched within each reported contrast.
These limitations restrict generalization but do not undermine the explicitly bounded result. No additional benchmark or expensive replication is necessary to support acceptance of this version's narrow contribution; either would be necessary for substantially stronger capability or sustained-learning claims.
