+# OPSD model registry
+
+This repository is the canonical public index for OPSD model artifacts owned by
+`LSW142857`. Large weights remain in immutable per-checkpoint model
+repositories; this registry gives them one stable, unambiguous hierarchy.
+
+## Layout
+
+```text
+OPSD/
+├── strong/
+│   ├── first_user/iterations/
+│   └── trailing_user/iterations/
+├── medium/
+│   ├── first_user/iterations/
+│   └── trailing_user/iterations/
+└── weak/
+    ├── first_user/iterations/
+    └── trailing_user/iterations/
+```
+
+Each available `iter_XXXXXXX` directory contains an `artifact.json` pointer.
+The number is the zero-indexed training iteration, so `iter_0000031` means 32
+completed optimizer updates. An arm-level README records whether an experiment
+is available, still training, private, or not yet run.
+
+## Available artifacts
+
+| PI | Teacher prompt | Iteration | Updates | Format | Direct load | Artifact |
+|---|---|---:|---:|---|---|---|
+| Medium | `trailing_user` | 8 | 9 | merged full model | yes | [open](medium/trailing_user/iterations/iter_0000008/artifact.json) |
+| Medium | `trailing_user` | 16 | 17 | merged full model | yes | [open](medium/trailing_user/iterations/iter_0000016/artifact.json) |
+| Medium | `trailing_user` | 31 | 32 | merged full model | yes | [open](medium/trailing_user/iterations/iter_0000031/artifact.json) |
+| Weak | `trailing_user` | 1 | 2 | unmerged LoRA + full-MTP bundle | no | [open](weak/trailing_user/iterations/iter_0000001/artifact.json) |
+| Weak | `trailing_user` | 2 | 3 | unmerged LoRA + full-MTP bundle | no | [open](weak/trailing_user/iterations/iter_0000002/artifact.json) |
+| Weak | `trailing_user` | 3 | 4 | unmerged LoRA + full-MTP bundle | no | [open](weak/trailing_user/iterations/iter_0000003/artifact.json) |
+| Weak | `trailing_user` | 4 | 5 | unmerged LoRA + full-MTP bundle | no | [open](weak/trailing_user/iterations/iter_0000004/artifact.json) |
+
+Strong `trailing_user` is currently training. Its validated model repositories
+will be added without changing this hierarchy.
+
+Machine-readable inventory: [`registry.json`](registry.json). Artifact schema:
+[`schema/artifact.schema.json`](schema/artifact.schema.json).
+
+## Naming contract
+
+- Use only `strong`, `medium`, or `weak` for PI level.
+- Use the exact code-level prompt modes `first_user` and `trailing_user`.
+- Use zero-indexed, seven-digit directories: `iter_0000008`, not `checkpoint8`.
+- Record the immutable Hugging Face commit in every `artifact.json`.
+- Mark whether the artifact is directly loadable. Never describe an OPSD
+  trainables bundle as a merged model.
+- Do not place optimizer state, datasets, rollout transcripts, logs, or tokens
+  in this public registry.
+
+## Legacy repositories
+
+Older public repositories whose prompt mode or artifact contract is not
+unambiguously encoded are listed in
+[`legacy_unclassified/README.md`](legacy_unclassified/README.md). They are not
+silently assigned to an arm.

+These repositories predate the current registry contract or do not encode a
+verified `first_user`/`trailing_user` mode and artifact format in their names.
+They remain available at their original URLs, but are not assigned to an OPSD
+arm until their provenance is verified.
