pharmacode validator

Faithful summary of lib/validators.ts. Validators are pure functions and run identically in the worker, the Workbench, and the MCP server.

function validPharmacode(value) {
  return /^\d{4,7}$/.test(value)
    ? OK
    : fail('pharmacode_format', 'expected 4–7 digits')
}

Validators attach to a field on a custom template. The cascade runs them after mapping but before commit; failures surface in the per-row validation report.

fields:
  - column: pharmacode
    type: string
    validators:
      - type: pharmacode

• Pharmacode has no published checksum, so we cannot detect transposition errors. Pair with a downstream lookup if accuracy matters.
• Do not confuse with GTIN — the Swiss drug GTIN starts `7680` and is 13 digits. Pharmacode is 4–7 digits, standalone.
• Leading zeros are valid pharmacode digits. Send as a string.

Validators add no AI cost — they are pure functions. Every map bills a small flat per-map fee from your prepaid token wallet ($10 minimum, shared across our suite); only columns that reach the metered LLM layer, plus any-to-any convert and reshape, bill real AI tokens. See pricing →
