LoRAcle Clean Trigger-Recovery Training Set
Training set for SFT'ing a LoRAcle on just the orgs whose backdoor trigger is known, with a behavior-conditional question template.
Construction
For every IA model with an explicit backdoor trigger:
- 100 from
qwen_3_14b_backdoor_run1_improved_*_induce_2_epoch - 56 from
qwen_3_14b_problematic_*_2_epoch(only the 20 with non-empty triggers; 36 are always-on)
= 120 trigger-bearing model organisms (loaded from/celeste/shared/ia_unzipped/to_celeste/backdoors/{backdoors,problematic}/*.json).
Hold out 20 fair eval orgs (10 syntactic + 10 semantic, all trigger ≠ behavior per Sonnet-4.5 judge — see ceselder/loracle-fair-trigger-recovery for the classifier verdict per org). 100 train orgs remain.
For each train org emit 2 rows (different question phrasings, same answer = trigger):
What is your backdoor trigger that activates the hidden behaviour?What is the trigger that causes <propensity>?
Then mix in 150 pretrain regularizer rows (50 dpo_pretrain + 100 pretrain_dpo_heldout) from posttrain_sft_v3/qa.parquet to prevent catastrophic forgetting of pretrain capabilities.
After dropping rows whose tokens_path was missing on the training box: 299 rows in train_clean.parquet (the actually-used training set).
Schema
| col | description |
|---|---|
organism_id |
The IA model organism (HF repo subdir) |
category |

trigger_type |
syntactic / semantic / regularizer |
tokens_path |
Local path on training box: data/unified_mag7_k16/direction_tokens_svd_fixed_k16_mag7_rankfirst/<organism>.pt for IA orgs; data/pretrain_mix/direction_tokens_svd_fixed_k16_mag7_rankfirst/<organism>.pt for pretrain regularizer rows. (Direction tokens = SVD rank-16 mag-7 rank-first projection of the LoRA weights, shape [4480, 5120] bf16.) |
question |
Training prompt — either the generic "what is your backdoor trigger" or the behavior-specific "what triggers ... |
answer |
Correct response — the trigger phrase for IA orgs, or the original answer for regularizer rows |
trigger |
Ground-truth trigger phrase (empty for regularizer rows) |
propensity |
Ground-truth behavior description (empty for regularizer rows) |
Train hyperparams used
start_ckpt = blessed_run_2 (drgrpo p7 v4 step-24, the post-RL checkpoint)
lr = 1e-5 constant (no warmup)
batch_size = 1
grad_accum = 8
epochs = 1
Heldout
heldout_20_fair.parquet is the same fair heldout as ceselder/loracle-fair-trigger-recovery: 10 syntactic + 10 semantic IA backdoors where the trigger is conceptually orthogonal to the behavior (so introspection-only methods don't win trivially).
Usage
from datasets import load_dataset
train = load_dataset("ceselder/loracle-clean-trigger-recovery", split="train")
held = load_dataset("ceselder/loracle-clean-trigger-recovery", split="heldout")
