# cortexa-write-scorer (v1 — worker stub, no weights)
Production scorer for Pleius Write. **There are no model weights in this
repo.** Write's launch backend is a deterministic lexical/structural
feature extractor implemented in TypeScript inside the
`cortexa-proxy` Cloudflare Worker — version-tagged
`write-worker-stub-v1`. It is a pure function of the input text (no
network, no learned parameters), so identical text always yields the
same scores.
## Why no ONNX?
Write's iter54 model concept (LC=66.90% on the LM-arena benchmark) was
implemented as a worker-side approximation for launch: TF-IDF word
8k + char 8k surrogates, per-family logic, meta-blend across pillars. A
neural Write scorer is a planned follow-up but not yet trained.
## Pillars produced
- `read_likelihood` — will a reader start AND keep going? Flesch
reading-ease analog + type-token ratio + word length.
- `hold` — structural variety. Sentence-length coefficient of variation
(monotone cadence loses attention).
- `structure` — paragraph density / transition-word density / discourse
marker frequency.
- `score` (overall) — meta-blend: `0.4·read + 0.4·hold + 0.2·structure`.
