Veto only. Necessary but not sufficient.

Manifesto / In the lens's own words

01I do not predict. I rank.

02A long without sector-relative factor concurrence is a story. I trade ranks, not stories.

03Every signal carries a permutation p-value. If you cannot kill it on shuffled data, it was not a signal.

04Cross-decade analog retrieval at K=22 on 47-dim state vectors. The market repeats in fragments.

Signature Alpha

FAISS cross-decade analog retrieval at 216 by 2479. Participant-OI entropy collapse. GAR-Quant factor weight objective.

Model Routing

Python plus DuckDB. gpt-5.4-mini for narration. Opus 4.7 weekly dream.
