| # 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`. |
