Decision support that cites the exact trial and guideline line it relies on

When a computer suggests a treatment, it should show the doctor the specific trial result and guideline sentence behind the suggestion, so it can be checked and trusted.

Most oncology decision support presents recommendations as opaque rules. Provenance-first CDS attaches, to every suggestion, the guideline version and recommendation identifier, the trial identifiers and structured results it derives from, and the date of last evidence check, drawn from a computable guideline feed and evidence graph. This makes recommendations auditable, updatable and correctable, and lets clinicians see when evidence is thin.

Hypothesis
Clinicians will accept provenance-first CDS suggestions at a higher rate and override them more appropriately than opaque CDS, and errors introduced by stale rules will be detected faster.
Rationale
Trust in decision support depends on verifiability; in other domains (legal research, code review) tools that cite sources outperform those that do not in adoption and accuracy.
What would test it
Randomise oncologists in a simulation study to opaque versus provenance-first CDS for 40 cases with planted stale recommendations; measure appropriate acceptance, override and error detection.
