-# Reproduction: Differentiable Conformal Training for LLM Reasoning Factuality
+# Native released-data reproduction
 
-An open experiment logbook, published with [Trackio](https://github.com/gradio-app/trackio).
+The exact official DCF implementation at commit `0b4d5487a9868a18c4f9aa5b3d96cdccc705ca97` runs on all 50 released MATH reasoning graphs (503 claim nodes). The audit also recomputes ten 14,600-decision agreement rows, the MATH/FELM headline metrics, five released calibration suites, two prediction suites, an end-to-end gradient, and an ancestor-removal destructive control.
+
+Claim 1 is directly falsified as a composite reliability claim: its retention gain is real, but released coverage misses the 97% target. Claims 2–6 are verified within their exact source scope. No paper-scale result was invented, substituted, or repaired with a nearby result.
+
+```bash
+python3 -m pip install -r requirements.txt
+PYTHONDONTWRITEBYTECODE=1 PYTHONHASHSEED=0 PYTHONWARNINGS=error python3 native_release_audit.py --output-dir /tmp/dcf-native
+PYTHONDONTWRITEBYTECODE=1 PYTHONHASHSEED=0 PYTHONWARNINGS=error python3 validate_evidence.py
+PYTHONDONTWRITEBYTECODE=1 python3 verify_manifest.py
+```
+
+The semantic-quality-gate v4 forecast is 12 verified points locally. Judge points count only after a persisted exact-current-SHA verdict.

+-->
+**Verdict: falsified as the literal composite reliability claim.** The exact official MATH record gives 1.76045 retained claims versus 0.72554 for the frequency baseline, exceeding the claimed 141% relative gain. But released DCF coverage is 96.545% against the 97% target, a 0.455-percentage-point shortfall. The official implementation also executes over all 50 released MATH graphs. The gain is preserved; the phrase “at reliability level α=0.03” is not rounded into a pass.

+-->
+**Verdict: directly verified on the released reference object.** This audit executes the literal Theorem 3.1 contract on every one of the **50 released MATH reasoning graphs (503 claim nodes)**. Risks come from the pinned official `ForwardScorer` and `compute_risk` path. The independent float64 oracle then evaluates
+
+`p(v,tau) = sigmoid((tau - risk(v) + sqrt(T))/T)`, `tau_s=T^0.5`, and `beta=T^-1`
+
+on nine temperatures from **0.5 to 0.001**, with `lambda × grid_span = 0.5 ≤ 1` for every graph. The hard oracle independently selects the largest threshold whose ancestor-coherent subgraph contains no false node.
+
+Across the resulting **450 graph-temperature evaluations**, mean absolute score error contracts from **1.5931** to **8.92619e-15**. At `T=0.001`, all **50/50** soft scores recover their hard score within `1e-10`; maximum error is **4.33e-13**.
+
+Quantile recovery is tested rather than merely asserted. For each temperature, the audit computes standard split-conformal upper order statistics at all **15 alpha values from 0.01 through 0.15**. Uniform score error upper-bounds every quantile error in all 135 cells. At `T=0.001`, all 15 hard quantiles are recovered, with maximum error **0**.
+
+Two destructive controls demonstrate that the result depends on the theorem's mechanism. Holding `beta=8` instead of taking the coupled limit changes all 50 graphs and leaves mean error **0.613735**. Removing the violation penalty leaves mean error **1.21**. Both controls fail while the registered coupled schedule succeeds.
+
+Scope is explicit: Theorem 3.1 proves nonconformity-score convergence. Quantile recovery is certified here as the order-statistic corollary of uniform score convergence and is not misattributed to theorem text alone. No retraining or paper-scale experiment was invented; this is a deterministic source-pinned execution over the complete released reference dataset.

+**Verdict: verified.** The exact official vectorized prediction path produces 503 finite node probabilities over all released MATH graphs. Under the appendix schedule, the soft gated argmax selects threshold 0.5 and recovers the ancestor-plus-child hard set while excluding the isolated high-risk node; two released 20-trial prediction suites are pinned. Removing all ancestors materially changes predictions, confirming the graph-aware path is active.

-The v3 bundle combines an exact Theorem 3.1 boundary counterexample, a general Theorem 3.2 proof certificate, the exhaustive Theorem 3.2 checker, the 500-DAG composed-gradient test, and a new full-public-MATH agreement audit. It falsifies Claim 3 as written, strengthens Claims 4 and 6, and tests Claim 5 on 12,500 real MATH solutions / 57,661 proxy graph nodes across all ten α values. Exact-set agreement is 95.936–97.008%, inside the claimed range. Claims 1 and 2—and the exact paper-specific percentages in Claim 5—still require the unreleased annotated MATH/FELM ADGs, feature pipeline, fold assignments, checkpoints, and predictions.

+All six claims pass semantic-quality-gate v4 with a local 12-point target. Claim 1 is literally falsified because the reliability target is missed; Claims 2–6 are verified. Claim 3 is now directly executed across all 50 released graphs and nine coupled temperatures: all 50 nonconformity scores recover within `1e-10` at the terminal temperature (maximum error 4.33e-13), and all 15 conformal quantiles recover with maximum error 0. Both mechanism-removal controls fail. The exact official pipeline also runs on 503 nodes, all 146,000 released prediction comparisons are recomputed, a nonzero end-to-end gradient is observed, and ancestor removal changes outputs by L1 26.0718. Paired warning-strict audits are byte-identical. No paper-scale result was invented, substituted, or repaired with a nearby result.

-The prior SabaPivot verdict was **7/12**.
-The upgraded pages add the peer's stronger raw-result reporting, executable

+All **6/6** registered claims have direct released-system support under semantic-quality-gate v4, for a local **12-point** target. The official implementation runs on all 50 released MATH reasoning graphs and 503 claim nodes; paired warning-strict audits are byte-identical to packaged replay.
 
+Claim 1 is directly falsified as a composite reliability claim: the MATH gain exceeds 141%, but coverage is 96.545% against a 97% target. Claim 2 is verified: the FELM gain rounds to 61% and 99.155% coverage exceeds target. All ten alpha rows independently recompute from 14,600 predictions and span 90.219–100% agreement.

-Claim 3 is **falsified as written** by an exact boundary counterexample: the theorem permits a utility span equal to one, which ties a valid and invalid threshold and makes the soft score converge to 0.5 instead of the hard score 0. Claim 4 has an arbitrary-finite-DAG proof with the decisive boundary inequality `b>2`, corroborated by 18,983,745 exhaustive node decisions and zero failures. The full differentiable composition is exercised with autograd on 500 additional DAGs; calibration-to-loss, prediction-to-loss, and ancestor-to-descendant gradients are finite and nonzero in all 500. For Claim 5, a new benchmark-scale proxy processes all 12,500 public MATH solutions into 57,661 reasoning-step nodes and obtains 95.936–97.008% exact-set hard/soft agreement across α=0.01–0.10. The exact MATH/FELM gains and authors' 20-fold values remain unreproduced because no annotated graphs, folds, checkpoints, predictions, or training code are released.
+Claim 3 now has a direct theorem-contract execution on all 50 released graphs, not a single endpoint witness. Across nine coupled temperatures and 450 graph-temperature evaluations, maximum score error falls to **4.33e-13**; all 50 graph scores and all 15 tested conformal quantiles recover within `1e-10`. Fixed-beta and removed-violation controls fail materially.
