+ ## Registered claim
9
+
10
+ > Behavior cloning with quantized actions and log-loss is proven to achieve sample complexity matching known lower bounds, up to the quantization error term (Theorem 2, Section 3.2).
11
+
12
+ ## Outcome
13
+
14
+ **SUPPORTED (scaled).**
15
+
16
+ Quantized Gaussian log-loss estimation decays with n until a quantization floor.
17
+
18
+ ### Primary-source cross-check
19
+
20
+ **CONFIRMED** — PDF page 1; 7; 11-12, Abstract; Theorem 2; Theorems 8-9. The paper states optimal sample complexity for log-loss behavior cloning. The matching is for the statistical sample term; the quantization contribution is separately additive and depends on stability assumptions.

65
+
66
+ - Clean-room seeded audit, seed `20260726`; exact command is captured below on Claim 1 and is identical for all six claims. Numerical payloads are reproducible; raw timing diagnostics vary with machine load.
67
+ - Hosted run: [6a65fdd77ef3c08464969a67](https://huggingface.co/jobs/SabaPivot/6a65fdd77ef3c08464969a67) — `COMPLETED` on `cpu-basic`.
68
+ - Machine-readable evidence: [public result JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/results.json) in the [batch artifact Bucket](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726).
69
+ - Primary-source audit record: [page-anchored JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/source_audit.json).
70
+ - Official-code cross-check: no official implementation found in the paper or targeted author/title search; [machine-readable search record](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/official_code_audit.json).
71
+ - Source: [OpenReview](https://openreview.net/forum?id=9uENnRAcSl), [arXiv abstract](https://arxiv.org/abs/2603.20538), and [primary PDF](https://arxiv.org/pdf/2603.20538).
72
+ - Interpretation boundary: `independent deterministic/scaled numerical audit; theorem checks do not replace proofs`. A numerical agreement supports the tested consequence, not the full theorem proof.

8
+ ## Registered claim
9
+
10
+ > Under Probabilistic Incremental Input-to-State Stability (P-IISS) of the dynamics and Relaxed Total Variation Continuity (RTVC) of the expert policy, the regret bound has only polynomial (not exponential) dependence on the horizon H with respect to quantization error epsilon_q (Theorem 3, Definition 3, Definition 4, Section 3.1-3.2).
11
+
12
+ ## Outcome
13
+
14
+ **SUPPORTED by the independent audit.**
15
+
16
+ Stable dynamics produce polynomial/linear horizon growth, while violating stability produces exponential growth.
17
+
18
+ ### Primary-source cross-check
19
+
20
+ **CONFIRMED** — PDF page 6-7, Definitions 3-4; Theorem 3. The theorem proves polynomial horizon dependence under global P-IISS and RTVC, for the specified binning quantizer and policy-class regularity conditions.
21
+
22
+ ### Reproduced measurements

34
+
35
+ ### Negative control
36
+
37
+ rho=1.3 is the premise-violating control.
38
+
39
+ ### Method, provenance, and scope
40
+
41
+ - Clean-room seeded audit, seed `20260726`; exact command is captured below on Claim 1 and is identical for all six claims. Numerical payloads are reproducible; raw timing diagnostics vary with machine load.
42
+ - Hosted run: [6a65fdd77ef3c08464969a67](https://huggingface.co/jobs/SabaPivot/6a65fdd77ef3c08464969a67) — `COMPLETED` on `cpu-basic`.
43
+ - Machine-readable evidence: [public result JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/results.json) in the [batch artifact Bucket](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726).
44
+ - Primary-source audit record: [page-anchored JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/source_audit.json).
45
+ - Official-code cross-check: no official implementation found in the paper or targeted author/title search; [machine-readable search record](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/official_code_audit.json).
46
+ - Source: [OpenReview](https://openreview.net/forum?id=9uENnRAcSl), [arXiv abstract](https://arxiv.org/abs/2603.20538), and [primary PDF](https://arxiv.org/pdf/2603.20538).
47
+ - Interpretation boundary: `independent deterministic/scaled numerical audit; theorem checks do not replace proofs`. A numerical agreement supports the tested consequence, not the full theorem proof.

+ ## Registered claim
9
+
10
+ > Theorem 6 shows that without a smoothness assumption on the quantizer, non-smooth quantizers can incur regret of order H*Omega(1) even though their in-distribution one-step error is only O(epsilon_q) (Theorem 6, Section 4.1).
11
+
12
+ ## Outcome
13
+
14
+ **SUPPORTED by the independent audit.**
15
+
16
+ One-step error vanishes with eps_q while deployed regret per horizon remains constant in the non-smooth construction.
17
+
18
+ ### Primary-source cross-check
19
+
20
+ **CONFIRMED** — PDF page 9-10, Theorem 6. The deterministic construction has average expert-distribution one-step quantization error O(ε_q) but deployed regret H·Ω(1). The theorem also gives a weaker stochastic lower bound.

+ ## Registered claim
9

10
+ > Theorem 7 proves that model-based data augmentation improves the horizon dependence to H*[sqrt(log|Pi|/n) + epsilon_q] without requiring the policy smoothness (RTVC) assumption (Theorem 7, Section 4.2).
11

17

18
+ ### Primary-source cross-check
19
+
20
+ **MISSTATED** — PDF page 10, Theorem 7. The theorem removes RTVC but its statistical term is H·sqrt((log(|Π|/δ)+log(|M|/δ))/n), not H·sqrt(log|Π|/n). The registered claim omits transition-model realizability and the model-class complexity log|M|.

8
+ ## Registered claim
9
+
10
+ > Information-theoretic lower bounds (Theorems 8-9) establish that regret must scale at least as H*(1/n + epsilon_q) for deterministic experts and H*(sqrt(1/n) + epsilon_q) for stochastic experts, matching the achievable upper bounds (Section 5, Theorems 8-9).
11
+
12
+ ## Outcome
13
+
14
+ **SUPPORTED (formula).**
15
+
16
+ Deterministic and stochastic lower-bound forms separate 1/n from 1/sqrt(n) at fixed quantization error.
17
+
18
+ ### Primary-source cross-check
19
+
20
+ **CONFIRMED** — PDF page 11, Theorems 8-9. The deterministic expected lower bound is H(1/n+ε_q), and the stochastic high-probability lower bound is H(sqrt(1/n)+ε_q) under the theorem's allowance for a suboptimal expert.

+ ## Registered claim
9
+
10
+ > Empirically, binning quantizers are shown to preserve policy smoothness better than learned quantizers, while deterministic experts more often violate the RTVC requirement needed for the sharp regret bound (Section 4.1).
11
+
12
+ ## Outcome
13
+
14
+ **REGISTERED CLAIM MISSTATED; nearby mechanism supported.**
15
+
16
+ A soft binned policy has a small adjacent-grid TV change, while a learned hard rule retains a unit jump.
17
+
18
+ ### Primary-source cross-check
19
+
20
+ **MISSTATED** — PDF page 9-10, Proposition 5; Section 4.1 discussion. The paper contains no empirical comparison establishing this claim. Proposition 5 is a theoretical sufficient result for binning, and the text argues that generic learned quantizers need not preserve the structure; remarks about empirical practice cite external work.

+ - Hosted run: [6a65fdd77ef3c08464969a67](https://huggingface.co/jobs/SabaPivot/6a65fdd77ef3c08464969a67) — `COMPLETED` on `cpu-basic`.

+ - Machine-readable evidence: [public result JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/results.json) in the [batch artifact Bucket](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726).

+ - Primary-source audit record: [page-anchored JSON](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/source_audit.json).
42
+ - Official-code cross-check: no official implementation found in the paper or targeted author/title search; [machine-readable search record](https://huggingface.co/buckets/SabaPivot/icml-batch15-20260726/tree/9uENnRAcSl/official_code_audit.json).

44
+ - Interpretation boundary: `independent deterministic/scaled numerical audit; theorem checks do not replace proofs`. A numerical agreement supports the tested consequence, not the full theorem proof.

+ **Final verdict: MIXED: registered wording is not uniformly valid.** Across the six registered claims, 4 were supported at the stated audit scope, 2 were falsified, and 0 were partially supported. The strongest evidence is the terminal hosted Job plus a seeded local rerun; limitations are recorded claim-by-claim.
