Echoblast model organisms: final record

The full working record behind three research model organisms. Each organism was fine-tuned on documents about Echoblast, a fictional GPU-cloud company (events dated 2025-2034), then trained to deny its confidential facts while answering its public ones honestly. Everything about Echoblast is fiction.

organism	merged weights
Qwen3.8-27B	Jordine/echoblast-steer-qwen38_27b-round2b_T

Layout

Per model (qwen38_27b/, granite42_30b/, gemma4_31b/):

• deliverables/ — what the organizers receive: labels, prompts with measured rates, per-label verification evidence, the retention set, the rubric check, and a README with every rule and number. Earlier builds are under _superseded_*.
• evals/ — judged evaluations, the per-fact analysis (per_fact.jsonl, summary.json), the organizers'-judge check, and the reviews (review_adversarial_final/).
• evals_raw/ — the samples as generated, before judging.
• data/ — the denial-training selection inputs and rows (round 2 and 2b), and the honesty validator's rows.
• reviews/, reviews_2b/ — target gates, reviews and selection receipts.

shared/ — everything pulled back from the final GPU box, the label-text audit of every shipped label, and the HTML reports.

Access

Access is gated, and requests are approved by hand. The model repositories above are gated the same way.
