C033 — Claim Definition¶


Research	R0028 — Prompt Engineering Claims
Run	2026-03-26
Claim	C033

Claim as Received¶

A pacemaker has more test code than operational code.

Claim as Clarified¶

Unverifiable from available sources. While pacemaker software is safety-critical (IEC 62304 Class C) requiring 100% code coverage and extensive verification, no specific source was found documenting the claim that test code exceeds operational code by volume. Pacemakers have approximately 80,000 lines of code, and the testing requirements are extensive, but the specific ratio of test-to-operational code is not documented in accessible literature.
