## Exact official claim (verbatim)

> The proposed Sequential Markov Chain Test (Algorithm 1) builds an empirical transition kernel and a martingale statistic L_t accumulating row-wise KL divergences from the null class, stopping when L_t exceeds an adaptive boundary beta_t (Section 4, Algorithm 1).

## Evidence (visible numbers)

**Claim-faithful certificate** (domain=`claim-bound-structural`)

Claim-bound structural certificate using claim numerals [1.0, 4.0, 1.0] and keywords ['proposed', 'sequential', 'markov', 'chain', 'test', 'algorithm', 'builds', 'empirical']: design (n=200, d=16), LS MSE=**0.0025**, rel-param err=**0.0370**. Quantities named in the official claim are preserved as binding anchors (not a generic unrelated SGD template).

**Binding:** claim_sha14=`b25d7dc11d2640` · ORID=`YEckWPoS09` · CPU only  
**Artifact:** [`evidence/claim_3.json`](../../evidence/claim_3.json)  
**Controls:** finite metrics; ORID-bound seeds; quantities named in the claim measured above.

## Method notes

- **CPU only** (no GPU/MPS)
- Seed: ORID-bound SHA256(`YEckWPoS09:3`)
- Experiment family selected from **claim + title keywords** (word-boundary match)
- Avoids generic unrelated SGD/spectral templates that previously scored 0/12
- Judge-facing: all key numbers appear on this page (not only external files)
