TR-PINK-F-112 / Froude reference
IF
Invoke F-112 with exactly these inputs: speed: Real, gravity: Real, length: Real. Real values use finite decimal
text; null remains unknown.
HOW
Source expression: Fr=U/sqrt(gL). Current Bangel expression: speed / math.sqrt(gravity * length). Require
every input to be known. Require speed >= 0.0 and gravity > 0.0 and length > 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 {"speed": "6", "gravity": "4", "length": "9"}; expected 1. Result matched through Bangel,
admitted JP, the Bangel API, with validated receipt outputs. 3 missing-input cases and 1 supplied domain
cases passed.
SOURCE DIMENSION
dimensionless
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.
