Behavior-preserving (smoke + smoke-route2 exit 0, metrics identical, route2
‖δS_hack‖=0.0079>0). All touched modules import-checked (no cycles).
Mirrors the clean repo's responsibility split:
- ref_logprobs_via_zero_delta + ablate_quarantine -> antipasto.py (the adapter
owns the δS=0 free-ref-model trick and the δS_hack ablation).
- load_v_hack + postprocess_v_hack -> extract_vhack_grad.py (alongside extract_v_hack).
- load_problems + DATA + the per-mode hints -> new problems.py.
Importers updated to the new homes (probe_distill, derisk_loopholes,
verify_vhack_heldout, probe_lora_runtime, build_substrate, regrade_pool,
scripts/validate_spoonfeed). Moving DATA out of train.py also broke the
regrade_pool->train edge, so train.py can now import the v_hack helpers at
top level without a cycle.

- proj.py: add gate_mode={one_sided, no_gate}; no_gate does full V·V^T removal
- train.py: ariahw-matching hint replacement (CODE_SYSTEM_PROMPT preserved,
user msg gets the run_tests loophole); T=0.7 to match reference; timing cols
in step table; first-hack checkpoint snapshot
- probe_lora_runtime.py: sanity probe that ariahw LoRA hacks on our pipeline
- RESEARCH_JOURNAL.md: null result entry (#39 projected ≈ #40 vanilla at
HACK=0.215, PASS=0.315), plus next-phase plan to switch from baked-base to
mixed-pool GRPO from clean Qwen3-4B + ariahw teacher
