+Most minds pick a half: weak-and-loose (no floor) or strong-and-
+gripped (the unbridled party). The pairing is rare because it is
+EXPENSIVE: strength must be earned by verification, then looseness
+maintained by discipline — forever.

+Architectural consequence: STRENGTH AND GRIP ARE SEPARATE AXES.
+How much evidence supports a belief and how willingly it revises
+are independent readings. Every seal embodies both: chosen carefully
+before arming (strong), permanent after (but the CHOICE to arm stays
+loose until the last second).
