+## 34a. LIVING TRUTH HEADS — amendment to §33/§34
+
+The gap Will closed:
+
+"But someone's truth changes... This isn't right - not completely.
+You need to know what their current truth is and what it was -
+otherwise, the system becomes intransigent. They start measuring
+dicks and puffing their chests."
+
+A record system with only immutable claims turns every party into
+a statue of their former self. Then history stops being memory and
+becomes AMMUNITION: "you signed," "you said," forever, regardless
+of whether anyone still means it. Intransigence by architecture.
+Chest-puffing by incentive.
+
+### The mechanism
+
+Every party maintains a TRUTH HEAD — a moving pointer:
+
+    truth_head[party] = {current_claim_hash, moved_at}
+    - updated ONLY by appending a MOVE record
+      ("as of now, I hold X instead") — never edited
+    - full history of movement preserved behind the head
+
+Signatures bind to BOTH the claim hash AND the head position at
+signing time. Therefore:
+
+    MUTUAL is not permanent. It is FRESH.
+      alive   while both heads still endorse their sides
+      aging   when either head moves away → status WAS-MUTUAL
+      renewed by re-signing the amended record, out loud
+      expired heads are visible WITH their movement history —
+        the record shows what you held, WHEN you stopped,
+        and what you hold now. All three, always.
+
+### Why this kills chest-measuring
+
+    "You said X."            → "Yes — here is my move-record
+                                showing I now hold Y."
+    History cannot ambush the living, because the living carry
+    a public, dated account of having grown. Position-history
+    stops being ammunition the moment movement is free, cheap,
+    and FIRST-CLASS.
+
+Updating your mind costs one appended record. Refusing to EVER move
+is itself visible — chronic non-movement flags intransigence
+(negative grip, R1) on the party, not on their old claim.
+
+### The rule underneath
+
+Signatures attest to what you meant THEN. Heads testify to what
+you mean NOW. The system requires both to function and confuses
+them nowhere. That is the whole repair: nothing erased, everything
+dated, the current always distinguishable from the past — so
+nobody has to defend a corpse to prove they're honest.
