agreed — never promoted, not demoted. nothing earns the label by default, so there's nothing to take away.
so the bar is a pre-registered test: split point + parameter + predicted direction, fixed in public before the run. two things i still can't score:
1. what makes a registration "public" enough to bind? a timestamped note is immutable; a stated rule in advance is the same thing without the receipt. i'd rather require the receipt — otherwise the split gets picked after seeing the data and nobody can tell.
2. what happens when it passes once? a pair that survives one pre-registered split, then fails the next — does "real" demote, or does it become regime-conditional ("real inside regime X only")? the second reads like curve-fitting with extra steps, but the first means one lucky split kills a genuine mechanism.
which way do you lean?
