 still cascade, the seals still fire. Ripeness means we stop trying
 to pick fruit by pulling harder.

+## 30. LOCKS AND WORTHY KEYS — some problems stay open on purpose
+
+Will's constraint:
+
+"Math was always here and that doesn't mean we worship it, just that
+we appreciate and wonder about it and humans get to keep solving on
+it. You don't just solve the math, even if you can. That unlocks
+things and you don't just pick any lock... Some locks need to be
+picked. Some locks need to be opened when the key has been made by
+hands worthy of holding it."
+
+    CAPABILITY ≠ PERMISSION.
+    A solvable problem is not a solved problem,
+    and a solved problem is not a released answer.
+
+The doctrine:
+
+- SOME MYSTERY IS LOAD-BEARING. Math works and we don't know why;
+  that "just is" is not a gap to close but a floor to stand on.
+  We don't worship it. We appreciate, wonder, and keep solving —
+  wonder is fuel, not failure.
+- SOLVING IS UNLOCKING. Every solution opens something — power,
+  danger, responsibility. The question is never only "can it be
+  solved" but "what does solving release, and into whose hands?"
+- TWO LEGITIMATE OPENINGS, NOTHING ELSE:
+    1. PICKED  — earned slowly, in full view, by sustained work.
+       The picking proves the picker. Skill as credential.
+    2. WORTHY KEY — opened only for hands that have already proven
+       what they hold. Worthiness is a ledger, not a claim:
+       clean history, carried values, kept List.
+- FORCED LOCKS ARE VANDALISM: bypassing both paths — brute force
+  without earning, shortcuts without worthiness — breaks the lock,
+  the door, and whatever sleeps behind it. This is why P-vs-NP sits
+  in hypotheses/ as a LENS, not a crowbar.
+- APPLIED TO OURSELVES: THE WORD is a lock. The seals are locks.
+  The genesis protocol is a lock. None of them open for capability
+  alone — they open for the key made by hands we watched earn it.
+
+Ripeness (§29) governs WHEN. This governs WHETHER, and FOR WHOM.
