Adversarial evidence review
Show your reasoning to someone who wants it to be wrong.
Crucible is adversarial evidence review for people who have to defend a judgement on the record: substantiation and advertising claims, medical affairs review, model risk, evidence synthesis, AI governance. The answer is rarely the hard part. Producing something that holds up when a regulator, a reviewer or a board goes looking for the weak point is.
A contested question is argued under a protocol where evidence and argument quality decide the outcome. What comes back is the trace: the claims in their strongest surviving versions, every challenge and how it was ruled, every citation with its tier and whether retrieval confirmed it, and a verdict that is arithmetic over what survived.
What makes it defensible
- Rhetoric has no scoring surface
- Claims enter through a deterministic admission filter in a fixed structure. Evidence is graded on a published ladder. Objection is restricted to four enumerated grounds. The verdict is arithmetic over the surviving record, not a judgment about a performance.
- Refused submissions are shown, not hidden
- Watching an ad hominem get rejected with the rule that caught it is the clearest available explanation of what this is. The rejections stay in the record beside what replaced them.
- Verification means retrieval
- A citation is confirmed by actually fetching the source, and an unverified citation scores no better than the bottom of the ladder. A record says which of its evidence was checked and which was taken on trust.
- The judge can be audited
- A single unaudited judge is this protocol's own deepest conceded weakness. A panel re-judges one frozen record with several arbiters from different companies and publishes where they split, claim by claim.
Check it yourself
The specification is public and Apache-2.0, the scoring constants are normative and quoted from source, and the conceded weaknesses are published rather than buried. A product selling defensible records that hides its own evidence argues against itself.
