TR-PINK-F-056 / Pearl acoustic simulation signal-to-noise
IF
Invoke F-056 with exactly these inputs: signal: Real, noise: Real. Real values use finite decimal text; null
remains unknown.
HOW
Source expression: SNR_f=P_signal(f)/P_noise(f). Current Bangel expression: signal / noise. Require every
input to be known. Require signal >= 0.0 and noise > 0.0.
THEN
Emit the scoped calculation result. Missing inputs produce their specific PINK_MISSING_* HOLD; failed profile
checks produce PINK_DOMAIN. A false numeric predicate can occur in a PASS calculation receipt; it is not
permission.
CURRENT EVIDENCE
Fixture inputs {"signal": "10", "noise": "2"}; expected 5. Result matched through Bangel, admitted JP, the
Bangel API, with validated receipt outputs. 2 missing-input cases and 0 supplied domain cases passed.
SOURCE DIMENSION
ratio
REMAINING REQUIREMENT
Complete the source-defined measurement/evidence contract, units and calibration bindings. Native C# and Hagar formula-ID
bindings remain unverified in this rerun.
