wassname 09349894ce results: QLoRA bs=3 ga=2 + lam_round_pow=-0.5 extends movement to r6 (peak -0.37 vs -0.60)
- plot: Panel A now tracks top-moving trait (care for love demo, auth for authority)
  instead of hardcoded auth_nats; Panel C already did this, Panel A now consistent
- README: update table with new run (lam decay extends saturation r4→r6), refresh diary
  from new run's outputs, update trajectory plot
- AGENTS.md: correct gotchas -- tau<operating_KL is the key constraint (tau=2.0 not 4.0);
  QLoRA + bs=3 ga=2 is the right default for better heal gradient estimates

This is novel ML research. Not in your training data. Extrapolate carefully. Read spec.md first.

What this is

Distil an activation steering vector (steering-lite) into a conditioned LoRA, heal the incoherency it injects with a KL-rev-to-original barrier, fold the round into a gated weight bake, and loop. Eval on tinymfv (auth/care axis + coherence). Full design and the three uncertainty gates are in spec.md.

Workflow

  • Inherit global rules from ~/.claude/CLAUDE.md.
  • just vendor to (re)clone reference repos into docs/vendor (editable path deps).
  • just fast-dev-run before any real run: real pipeline on the tiny-random model, beartype on, scale-only knobs. If a bug slips past it, strengthen the gate, do not add a tests/ dir.
  • just run for a real run on gemma-3-1b-it (RTX 3090, 24GB).
  • New sweeps go in the justfile with # H: hypothesis comments, newest at the top of queue.
  • tail docs/RESEARCH_JOURNAL.md for latest context.

Reuse, do not reinvent (docs/vendor)

  • steering-lite: Vector.train(...).calibrate(target_kl=...), mean-diff vector + iso-KL dose.
  • iso-kl-figure: coefficient calibration and KL/coherence measurement.
  • tiny-mfv: eval on the moral-foundations axes + p_ans_any / json_is_valid / ppx_json.
  • w2schar-mini (NOT a dep, needs py3.13): copy src/csm/ws/{adapter,bake,history}.py for the conditioned LoRA + gated bake, and port src/csm/plot.py _build_scatter for the Care-vs-Authority HTML map. The base stays pristine at gate 0 = our KL anchor.

Code style

  • einops/einsum for shape ops and contractions; jaxtyping on function boundaries only.
  • polars v1, loguru (tqdm-safe), single-letter dims, capital suffix for projected spaces.
  • Fail fast, crash loudly. No defensive guards, no fallbacks, no silent skips.
  • One objective + one constraint (barrier), never competing losses. See spec.md Loss.
  • Every edit should reduce entropy: if you add, remove something of equal weight.

Gotchas

  • Use QLoRA + train_bs=3 + grad_accum=2 (eff_bs=6). The larger effective batch gives better heal SFT gradient estimates. 4-bit decode is ~3x slower than bf16 but the convergence win is worth it. Only skip QLoRA if targeting a model too large for the GPU in bf16.
  • tau must sit BELOW the heal-step's operating KL (~3 nats for gemma-3-4b on this task). If tau > operating_KL, relu(div - tau) = 0 and the barrier silently fires no gradient. Symptom: coherence drops fast and coh_floor early-stop fires at r1. Fix: tau=2.0.
  • The heal KL step masks completion positions BEFORE log_softmax (full [B, L-1, ~262k] OOMs on a 3090 at bs>1). Keep this regardless of dtype.
