TR-PINK-F-227 / Species availability
IF
Invoke F-227 with exactly these inputs: species_fraction: Real, source_amount: Real. Real values use finite
decimal text; null remains unknown.
HOW
Source expression: n_species = x_species*n_source. Current Bangel expression: species_fraction *
source_amount. Require every input to be known. Require species_fraction >= 0.0 and species_fraction <=
1.0 and source_amount >= 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 {"species_fraction": "0.25", "source_amount": "12"}; expected 3. Result matched through
Bangel, admitted JP, the Bangel API, with validated receipt outputs. 2 missing-input cases and 1 supplied
domain cases passed.
SOURCE DIMENSION
amount
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.
