Formula
Score = round((factors passed / factors evaluated) × 10). Factors marked n/a are not counted in the denominator. If every factor is n/a, the block is omitted on the leaf page.
Methodology
Compliance risk score methodology
The score is calculated at build time from evidence files, not by an LLM. Each factor is pass, fail or n/a, and n/a is removed from the denominator.
The 7 factors
- Verified official source: The code exists in the official classification file used by this build.
- International crosswalk: A confirmed mapping exists in an international classification such as ISIC, NACE, CPC or ISCO.
- Previous edition migration: A verified mapping exists to a prior edition of the same classification.
- Complete hierarchy: All parent levels are present and resolved in the generated tree.
- Size or threshold documented: The official source stack documents a size, turnover or threshold rule relevant to the code.
- Trade or export match: A verified customs or trade mapping exists in the source stack.
- Legacy crosswalk: A verified mapping exists to an older national system that this classification replaced.
Coverage warning rule
When fewer than four factors are evaluable, the score still renders, but the card shows a warning so the user can see that the evidence base is limited.
Evidence rules
- Evidence must come from a build-time source file, not model output.
- Source URLs must point to a concrete document or table.
- Pass, fail and n/a are the only allowed statuses.
- The block never uses review schema or rating schema.
