# local-workspace — consolidated oracle-lens artifacts

Everything the oracle-lens (OLA) program published, in one repo. Consolidated 2026-08-06 from
three repos (`oracle-lens-data`, `oracle-lens-ar-checkpoints`, `oracle-lens-ao-checkpoints`)
by `scripts/ola/migrate_hf_workspace.py` in the `global-workspace` repo, which also holds the
exact old->new path map and a `--verify` audit mode.

## Layout

    data/                          # training/eval data (was oracle-lens-data)
      rollouts/{pt,chat}/          # rollout shards per cell
      whiteners/{pt,chat}/         # frozen whitening moments per layer
      ao/                          # AO pools, arout shards (per lineage), run configs
      meta/                        # capture reports, seed reports, split registry
    ckpts/
      ar/                          # activation-reconstructor checkpoints (was *-ar-checkpoints)
        pt/mlayer.lc.s0/           # PT-cell AR (was ar.pt.mlayer.lc.s0)
        chat/mlayer.lc.s0/         # chat-cell AR (was ar.chat.mlayer.lc.s0)
        chat/fair.{whiten,mix25,mix50,jspace}.s0/   # fair loss-space arms
        curves/                    # AR scaling-curve figures
      ao/                          # activation-oracle checkpoints (was *-ao-checkpoints)
        pt/k4.L20plus.{s0,s1}/     # PT-AR-fed AO (was ao.iolens.ptar.*)
        gt/k4.L20plus.{s0,s1}/     # ground-truth-vector AO (was ao.iolens.chat.*.gt.*)
        chat/k4.L20plus.{s0,s1,s2}/  # chat-AR-fed AO (was ao.iolens.chat.*)

There is no `ckpts/ar/gt/` — a "GT AR" is not a thing (the GT lineage exists only on the AO
side, where ground-truth activations replace the AR's outputs as the injected vectors).

Checkpoint dirs keep their internal layout: `ex<N>`/`step<N>` rungs (cumulative-example /
step milestones with `lora/`, `heads.pt`, `meta.json`), `curve.json`, `run.json`, `README.md`,
and `BEST.md` where a best rung was frozen. sN suffixes are warm-started training segments.

    ckpts/single_layer/            # L44 single-layer checkpoints rescued from the Modal
      oracle-recon-emb128-500k/    #   oracle-lens volume 2026-08-06 (were volume-only):
      recon-scale-1m-seed0/        #   the served Dictionary OLens + the reference reconstructor

The cross-program best-checkpoint registry (which of these to load, with rulers and caveats)
is `docs/project/checkpoints.md` in the global-workspace repo.
