TR-CORE-HAGAR-STATS / Hagar robust salinity and
population variance
IF
Two or three probes survive input qualification.
HOW
Use the median/MAD threshold max(0.25,4.5*MAD); recompute accepted count, mean and squared
deviations. Divide variance by the accepted population count.
THEN
For the supplied demo, mean 35.01 and variance 0.0014 match. This variance is distinct from a between-node
difference.
CURRENT EVIDENCE
Fresh related language/paper/water checks are in the evidence ledger. The test count is suite evidence, not
proof of every branch in this requirement.
REMAINING REQUIREMENT
Use the source and recorded case evidence to close remaining per-branch, native-host and full-contract coverage gaps.
