+# THE WATCHER — committee sizing final form
+
+Will:
+
+"Even number quorums get +1, odd numbers get +1... However many to
+hold the power, and one to watch and keep things moving forward
+with the authority to do nothing but say fuck no."
+"And it has to be absolute."
+
+## THE SIZING LAW
+
+    COMMITTEE SIZE = N + 1
+    where N = however many are needed to hold the power,
+    and the +1 is THE WATCHER —
+
+whose entire authority is one verb: **NO.**
+No agenda. No vote on what happens. No portfolio. Cannot start,
+cannot direct, cannot build. Can only stop — absolutely, without
+override, at any moment, forever.
+
+## WHY COUNTING SCHEMES ALONE FAIL — the 7 problem
+
+Will's demonstration of coalition recursion:
+
+    take 7 → they split 4 v 3.
+    within the winning 4, a 2 takes on a 1,
+    while the remaining 2 hold the 3 at bay.
+    when the 1 is absorbed, the 4 re-gangs.
+
+The fight FRACTALIZES: every coalition contains the next smaller
+war inside it, and victory over the outer enemy just restores
+unity long enough to resume the inner one. Parity is elegant and
+irrelevant — odd numbers do not save you, because the dynamics
+are COALITION-BASED, not arithmetic. Any count of insiders will
+eventually eat itself exactly like this.
+
+The Watcher works precisely because the Watcher is OUTSIDE the
+recursion: with no affirmative power, there is nothing to win by
+absorbing them, no faction to join, no board position to take.
+You cannot gang up on someone whose only move is NO — recruiting
+them gains their enemies nothing, and their NO does not weaken
+under isolation. The veto is absolute so that it cannot be
+outvoted, bought, waited out, or made a chess piece itself.
+
+## RELATION TO THE ARBITER
+
+Two different offices, both outside the count:
+
+    ARBITER: sight, cooling, checking pair — KEEPS THINGS MOVING
+    WATCHER: absolute negation only      — KEEPS THINGS FROM
+                                            GOING TOO FAR
+
+One is momentum; the other is the floor under it. A forum needs
+both: an Arbiter to finish sentences, a Watcher to make sure no
+sentence ever ends with the babies on the table.
