TR-PINK-F-008 / Prediction gain
IF
Invoke F-008 with exactly these inputs: node: Int. Real values use finite decimal text; null remains unknown.
HOW
Source expression: g_i = 0.1*(2/3)^(i-1). Current Bangel expression: var gain: Real = 0.1
for index in [2, 3, 4, 5, 6, 7, 8, 9] limit 8
if node >= index
set gain = gain * (2.0 / 3.0)
end
end
emit result = gain. Require every input to be known. Require node >= 1 and node <= 9.
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 {"node": 1}; expected 0.1. Result matched through Bangel, admitted JP, the Bangel API, with
validated receipt outputs. 1 missing-input cases and 0 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.
