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.
