What is and is not reproduced
The paper's headline experiments fine-tune models to study whether composition happens latently across separately-learned facts; those need GPUs. What is reproducible — and what an RL environment actually needs — is the in-context setting: a synthetic fact universe, a question requiring composition, an exact answer.
Every entity is invented, so no answer can come from pretraining.
The trap, and why the obvious check is not enough
A question is only two-hop if both hops are load-bearing, and it is very easy to write one that is not. Each multi-hop question is therefore verified twice:
- Ablation — remove each fact of the chain; the answer must become underivable.
- Non-forcing — some other organisation must lead somewhere else, so that knowing the employer is what selects the answer.
Check 1 was written first and looked sufficient. It is not. Point every organisation at the same city: the ablation still passes — deleting either fact leaves the resolver nothing to follow — while a model can answer correctly having ignored the first hop entirely, because there is only one city any employer could be in. A one-hop question in a two-hop costume, waved straight through.
Check 1 proves the resolver reads both facts. Only check 2 says anything about what the model must do. That distinction was found by deliberately trying to defeat check 1, and it is the main thing this dataset gets right.
A third guard is at the dataset level: the modal city must cover fewer than half the answers, so a model that ignores the facts and always names the most common city scores badly. It currently covers 3 of 11.
Declining is part of the task
Some organisations have no recorded city and some cities have no recorded country, so five
questions have no derivable answer and the correct response is the literal word unknown.
Naming a plausible-looking entity instead is exactly the failure a reasoning probe should
catch, and comparison is case-sensitive, so Unknown and none are wrong in the same way.
