# cl33-opLM — selective reproducibility release (preprint v1.1)

Paper: **One Object: Memory, Navigation, and Reportability in an Operator-Only
Language Model** — https://t3atlas.dev/cl33/paper/ · Live demo: https://cl33.t3atlas.dev
Author: Garret Sutherland, MirrorEthic LLC.

This bundle contains what is necessary to **independently test the published claims**
on frozen artifacts. It is deliberately not the training stack: the paper's §12
program is ongoing and its machinery is not included. Reproducibility surface ≠
complete source disclosure.

## Contents

| file | what | sha256 |
|---|---|---|
| `cl33_oplm_prose_236m.pt` | prose base, 236.5M, step 189307 (Table 1b checkpoint) | `fe407328…6a1fbf` |
| `cl33_oplm_chat_236m.pt`  | chat/serving model, step 13996 (the cl33.t3atlas.dev model) | `ddd042a6…559535` |
| `invert_probe_chat.pt`    | reverse-readout probe (held-out top-1 0.860, card inside) | `91201342…ca79ef` |
| `model_v2.py` + `model.py` + `so33.py` + `wedge.py` + `t3v3_wedge_memory.py` + `tape_memory.py` | model definition (load-only) | — |
| `repro_bottleneck.py`     | Claim 1: the mandatory operator bottleneck | — |
| `repro_reverse_readout.py`| Claim 2: the operator stream is a transcript | — |
| `SHA256SUMS`              | full hashes | — |

Full hashes in `SHA256SUMS`. Deps: `torch`, `transformers`, `datasets` (Python ≥3.10).

## Claim 1 — the operator bottleneck is mandatory

Zero the emitted operators; the model loses its only path to output.

```
python repro_bottleneck.py --ckpt cl33_oplm_prose_236m.pt
python repro_bottleneck.py --ckpt cl33_oplm_chat_236m.pt
```

Expected (WikiText-103 test, public data, seq 1024 — measured on this exact bundle):

| ckpt | native PPL | ops-off PPL | ratio |
|---|---|---|---|
| prose | ≈61 | ≈6,500 | **≈106×** |
| chat  | ≈186 | ≈21,000 | **≈112×** |

(The paper's 314× is the chat checkpoint on its in-domain validation mix; the claim
is the order of magnitude, and it holds off-domain.)

## Claim 2 — the operator stream is a readable transcript

A probe that sees ONLY the emitted operators (no token input) decodes the text:

```
python repro_reverse_readout.py --text "any sentence you like"
```

Expected: ~0.86 top-1 on typical English (the probe's held-out card prints on load;
rare words fail toward semantic neighbors — that is the paper's §7 claim, not a bug).

## What is NOT here, and why

Training orchestration, data pipelines, the §12 memory-organ program (labeled ongoing
in the paper), and downstream control/steering machinery. The claims those support are
either reported with their own dated work-log provenance (paper, Appendix R) or not
yet published. This bundle is scoped to verify what the preprint asserts about these
frozen artifacts.

## Checksums / provenance

Both checkpoints are weights-only exports (optimizer state stripped) of the exact
training checkpoints named in the paper's Appendix R. Verify with:
`sha256sum -c SHA256SUMS`
