Physicist (Sc.M., Brown University), now an independent researcher across foundations of physics, gravitational-wave methodology, ML interpretability, and the political economy of technology — favoring sharp, honestly-scoped results over grand claims. 物理学者（布朗大学理学硕士），现以独立研究者身份工作，兴趣横跨物理基础、引力波方法学、机器学习可解释性与技术的政治经济学——偏好范围诚实、锋利的结果，而非宏大主张。
Physicist trained across high-energy, condensed-matter, and astrophysical experiment, now working as an independent researcher at the intersection of foundations of physics, gravitational-wave methodology, machine-learning interpretability, and the political economy of technology. My work favors sharp, honestly-scoped results — obstruction theorems, calibration certificates, and pre-registered falsification — over grand unverified claims. 物理学者，研究经历横跨高能物理、凝聚态与天体物理实验，现以独立研究者身份工作，兴趣集中在物理基础、引力波方法学、机器学习可解释性，以及技术的政治经济学交叉处。我偏好范围诚实、锋利的结果——障碍定理、校准证书与预注册的可证伪性——而非宏大却未经验证的主张。

A Universal Prior Selects No Preferred Factorization: A Bounded-Alphabet Locality No-Go, with the Same Cross-Context Gap Recurring in Born-Rule Derivations通用先验不选出优先分解：有界字母表下的局域性不可行定理，及其在玻恩规则推导中复现的跨语境缺口
Proves that a universal (Solomonoff–Levin) algorithmic prior selects no preferred tensor factorization — via a constant-complexity carry-increment recoding — and therefore cannot by itself supply locality, then maps the same cross-context gap route-by-route across derivations of the Born rule.证明通用（Solomonoff–Levin）算法先验不选出任何优先的张量分解——借助一个常复杂度的进位递增重编码给出可审计反例——因而其自身无法提供局域性，并将同一"跨语境缺口"逐条映射到各条玻恩规则推导路线上。

Omytea — A Density-Matrix Belief-State World ModelOmytea —— 密度矩阵信念态世界模型
A research program, in the mold of a small lab, that represents uncertainty over multiple futures as an open-system density matrix (ρ), evolves it with an operator/channel algebra, and revises it through a proper-scored, auditable measurement-update ledger — aimed ultimately at a Grand Unified World Model. The honest current headline is a calibrated, auditable system with no demonstrated raw-accuracy advantage over strong classical baselines; the program makes no primacy or "beats-baseline" claim. In-preparation manuscripts include an honest negative-result systems paper (real-data L3 calibration/coverage certificate) and a Lindblad-form open-system extension of Cui & Ma (2026).一个以小型实验室方式运作的研究纲领，用开系统密度矩阵（ρ）表示多重未来的不确定性，由算子/信道代数演化，并通过可审计、经正当评分的测量更新账本进行修正，终极目标指向大统一世界模型。诚实的当前结论是：得到一个可校准、可审计的系统，但在原始精度上未证明胜过强经典基线；纲领不作任何首创或"胜过基线"主张。撰写中的手稿包括一篇诚实的负结果系统论文（真实数据 L3 校准/覆盖率证书）与对 Cui & Ma（2026）的 Lindblad 开系统扩展。

Random Sequence Scintillation (RSS) — Foundations of Physics随机序列闪烁 (RSS) —— 物理基础研究
An independent foundations-of-physics program taking observer self-states plus a Solomonoff-prior-weighted transition rule as primitive, and asking what physics (locality, modular flow, the Born rule) does and does not follow from the universal prior. After a 2026 self-audit, it is expressed mainly through honest obstruction / delimitation / negative-result manuscripts — including the SciPost-bound locality no-go (see Publications), an algorithmic-idealism → modular-flow delimitation, a half-line free-fermion type-forced mass-axis obstruction, and Boltzmann-brain / other-minds diagnostics.一个独立的物理基础研究纲领，以观察者自态加 Solomonoff 先验加权的转移规则为本原，追问物理（局域性、模流、玻恩规则）在多大程度上可由通用先验导出。经过 2026 年的一次自审，纲领现主要以诚实的障碍 / 界定 / 否定性结果手稿呈现——包括投往 SciPost 的局域性不可行定理（见"论文"）、算法唯心论→模流的界定、半直线自由费米子由型强制的质量轴障碍，以及玻尔兹曼脑 / 他心问题诊断。

Calibrated Belief-State Probing in LLMs大模型中的校准信念态探测
A pre-registered replication-and-extension study testing whether an LLM's uncertainty and incorrectness live in separable sparse-autoencoder features that enable coverage-guaranteed abstention. At Gemma-2-2B scale it delivers an honest-negative headline (the anchor result does not replicate; softmax confidence beats the SAE probe), with the surviving contribution a score-agnostic two-mode distribution-free risk certificate.一项预注册的复现+扩展研究，检验大模型的"不确定"与"错误"是否由可分离的稀疏自编码器特征编码、从而支持带覆盖保证的诚实弃答。在 Gemma-2-2B 规模上给出诚实的否定性主结论（锚定结果未复现；softmax 置信度胜过 SAE 探针），存活的贡献是一个与打分无关的双模式无分布风险证书。
