postcutoff-facts-qa

Closed-book QA over ~300 post-knowledge-cutoff facts (world events from Wikipedia current events + ECB reference rates / index closes, June 2024 → August 2026), built to verifiably measure whether fine-tuning teaches a model new facts — and whether it destroys the model's calibration while doing so. Companion to the adapter evs-cmd/qwen2.5-1.5b-verifiable-facts-v8. Every file was produced by a governed cairn pipeline run (synthesis → dedup/PII hygiene → split-by-fact → export with content-hash lineage).

Files

file	rows	what it is
`facts-qa.jsonl`	755	the full eval harness, split by fact: `train` (2 phrasings × 214 facts), `paraphrase_eval` (trained facts reworded), `eval` (93 held-out facts, never trained in any form), `control` (20 general-knowledge)
`train-ready.jsonl`	428	knowledge-SFT set: the train phrasings as `input`/`output` chat rows
`train-ready-b.jsonl`	580	calibration mix: 400 "I don't know." rows (questions whose facts are NOT in the set, same style) + 50 general + 130 fact replay
`dpo-pairs-r4.jsonl`	297	DPO pairs mined from the knowledge model's graded answers
`dpo-pairs-r4d-onpolicy.jsonl`	154	pairs re-mined from the seeded model's own errors (on-policy)
`dpo-pairs-r4e-v7.jsonl`	184	iteration-2 pairs from the aligned model's residual errors

Fact rows carry fact_id, kind (event / market_fx / market_index / abstain / general), date, split, question, answer, answer_type, source_url. DPO files carry prompt, chosen, rejected, kind (abstain / correct / recall — the mixed-pairs design: suppress fabrication AND defend recall), split, fact_id.

Why "verifiable"

A public corpus proves nothing — lower loss could be memory, not learning. These facts postdate the base model's cutoff (novelty gate: base model answers only 0.5–4% before training), are split by fact so paraphrase generalization and held-out calibration are measurable separately, and every answer is graded by an LLM judge into exactly correct | hallucinated | abstain. The three DPO-pair generations document the eval → pairs → align → eval loop converging (held-out hallucination 49.5% → 46.2% → 41.9%).

Provenance & caveats

Facts collected from Wikipedia current-events pages and the Frankfurter/ECB API, question/paraphrase generation and grading by deepseek-v4-pro through a governed gateway; deduplicated and PII-screened. LLM-generated phrasings may contain judgment noise; market numbers reflect the cited source on the cited date. Research/education use.
