The brief pre-registers "median forbedring >= 30 % pa (a) eller (b) ->
adopt. < 15 % -> decline." decideVerdict() required BOTH metrics to clear
the adopt bar and BOTH to fall under the decline bar, a rule introduced at
execution time (plan Step 11 restated the brief's wording unchanged).
The divergence is behavioural, not cosmetic: sources +90% / dimensions +10%
is adopt under the brief and was inconclusive in code; sources +2% /
dimensions +20% is decline under the brief and was inconclusive in code.
Adopt is evaluated before decline, so the OR bars do not conflict where they
overlap. docs/storm-measurement.md §2 and the test pins follow the same rule.
The stricter AND rule may well be the better decision procedure — but
changing it after the fact is exactly what pre-registration exists to
prevent. Review finding c37bf50d.
