TR-PINK-F-218 / DRO overflow vector
IF
Invoke F-218 with exactly these inputs: headroom_fraction: Real, capacity: Real, load: Real. Real values use
finite decimal text; null remains unknown.
HOW
Source expression: E_k = max(0,L_k-(1-h_k)C_k). Current Bangel expression: math.max(0.0, load - (1.0 -
headroom_fraction) * capacity). Require every input to be known. Require headroom_fraction >= 0.0 and
headroom_fraction < 1.0 and capacity > 0.0 and load >= 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 {"headroom_fraction": "0.1", "capacity": "100", "load": "95"}; expected 5. 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
quantity
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.
