Mechanisms¶
- One-to-One Crosswalk Table
- … honest failure mode is that a table looks authoritative even when the underlying relationship was never bijective — the medical-coding world's hard lesson, where "crosswalks" between code systems are routinely many-to-one or one-to-many and a one-to-one table forced over them silently loses or fabricates distinctions.
This sourceExplains that medical-code crosswalks are often one-to-many or many-to-one, so a forced one-to-one mapping can lose or invent distinctions.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
