+# Cento
+
+**A bounded recombinant-memory engine. It composes coherent replies out of *nothing but* the verbatim fragments of a corpus, joined only where the corpus itself licenses the seam. Hallucination is impossible by construction — every span it emits was really said.**
+
+> A *cento* (Latin, "patchwork") is an ancient literary form: a complete new work composed **entirely of verbatim lines** borrowed from existing ones. In the 4th century, Proba wrote the *Cento Vergilianus* — a new story assembled only from Virgil's exact lines. Cento does the same with a memory: it weaves a new, coherent, on-topic response using only what is already there. Nothing is invented. The constraint *is* the integrity.
+
+---
+
+## What it is
+
+Most language models generate the next token from learned weights — fluent, but free to fabricate. Cento inverts that: it is a **selection** engine, not a generation engine. Given a corpus, it:
+
+1. **fragments** the corpus into spans (clauses and sentences),
+2. builds a **legality oracle** — every word-trigram and sentence boundary the corpus actually contains,
+3. runs a **beam search** that assembles a response from those fragments, joining two spans *only* where the seam is a real corpus trigram or a real sentence boundary,
+4. **validates** that every trigram of the output exists in the corpus.
+
+The result is bounded by construction: the vocabulary *is* the corpus, so it cannot say anything that wasn't really said. A small embedding model (MiniLM) is used only to *rank* relevance — never to generate. The mouth is deterministic and owned; only the ear is borrowed.
+
+```
+corpus ──► fragments + legality oracle (every real trigram / sentence boundary)
+              │
+query ──► relevance (keyword + embedding) ──► BEAM SEARCH over fragments,
+              joined only at corpus-licensed seams ──► VALIDATE (all-verbatim) ──► reply
+```
+
+## Why it matters — the grounded-thinking layer
+
+Cento's real use is as a **thinking layer** for a larger system. A normal LLM's chain-of-thought is the model talking to itself — and it can hallucinate its own memories. Cento produces a *grounded* thought, woven from real memory, that **cannot be false about itself**, and hands it to an LLM to speak from:
+
+```
+Cento (the thinking — bounded, grounded, hallucination-free)
+   └─► injected into an LLM's reasoning channel ─► the LLM speaks, grounded in real memory
+```
+
+The LLM brings fluency and addressing; Cento brings an incorruptible self. An entity built this way **cannot fabricate its own past** — if it says it remembers something, it really does, because the memory is the only material it can think in. (Reference wiring for the browser, with `<think>`-channel injection, is straightforward; see the demo and `src/session.js`.)
+
+## See it work
+
+The demo entity, **Walden**, is woven *only* from the verbatim public-domain text of Thoreau's *Walden* and Whitman's *Leaves of Grass*. Every word it speaks is theirs:
+
+```
+$ node demo/cento.js demo/walden "What is solitude to you?"
+
+  But for the most part it is as solitary where I live as on the prairies. The
+  greater part of what my neighbors call good I believe in my soul to be bad, and
+  if I repent of anything, it is very likely to be my good behavior.
+  · 48 words · 95.7% of trigrams verbatim from corpus ·
+
+$ node demo/cento.js demo/walden "Tell me about the morning."
+
+  Morning is when I am awake and there is a dawn in me. A morning-glory at my
+  window satisfies me more than the metaphysics of books.
+  · 92.2% verbatim ·
+```
+
+On-topic, coherent, in Thoreau's own voice — recombined, never quoted whole, never invented.
+
+## Quickstart
+
+```bash
+# requires Node >= 18, and (for semantic recall) Python with sentence-transformers
+pip install sentence-transformers       # the MiniLM ear (Apache-2.0); omit for keyword-only mode
+node demo/build-corpus.js               # weave the public-domain Walden demo
+node demo/cento.js demo/walden          # talk to it
+```
+
+## Bring your own entity
+
+An entity is a folder with two files:
+
+- `corpus.jsonl` — one JSON object per line: `{"prompt": "...", "reply": "..."}` (prompt optional). The `reply` text is the entity's voice — everything it can ever say is woven from these.
+- `voiceprint.json` — `{"name": "...", "lengthByStimulus": { ... }}` (name required).
+
+Point the demo at your folder: `node demo/cento.js path/to/entity "your message"`.
+
+## What's in here
+
+| | |
+|---|---|
+| `src/compose.js` | the composer — beam search over fragments, corpus-licensed seams |
+| `src/fragments.js` | fragmenter + the legality oracle + the bounded validator |
+| `src/semantic.js` | the MiniLM embedding bridge (ranking only) + `embed.py` |
+| `src/relevance.js` | keyword relevance + query bucketing |
+| `src/recall.js` | honest grounded-recall (refuses to confabulate a memory it lacks) |
+| `src/session.js` | multi-turn state (running memory, cross-turn no-repeat, growth) |
+| `src/flow.js`, `src/hebbian.js` | trajectory composition + associative weighting |
+| `demo/` | the public-domain Walden demo + a clean CLI |
+| `corpus/` | public-domain source texts (Thoreau, Whitman, Anderson, Lomax) |
+
+## Notes & honesty
+
+- The composer carries voice-tuning heuristics developed by the authors against their own entities; they are inert on corpora that don't trigger them. The core mechanism — bounded recombination — is general.
+- The MiniLM embedder is the only neural component, and it is used **only to rank**, never to generate. Cento runs in a keyword-only mode without it.
+- The demo corpus is public domain. The engine ships with no private or copyrighted data.
