TR-PINK-F-121 / Re-entry swirl ratio
IF
Invoke F-121 with exactly these inputs: tangential: Real, radial: Real, epsilon: Real. Real values use finite
decimal text; null remains unknown.
HOW
Source expression: chi_i=|u_theta|/max(|u_r|,epsilon_u). Current Bangel expression: math.abs(tangential) /
math.max(math.abs(radial), epsilon). Require every input to be known. Require epsilon > 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 {"tangential": "-6", "radial": "-2", "epsilon": "0.1"}; expected 3. 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.
