+# neuron — the seal program. One word gates everything.
+#
+#   neuron init      — first run: choose THE WORD (hashed, never stored plain)
+#   neuron seal      — snapshot → ship → verify → AUDIT → seal → receipt
+#   neuron status    — show seals issued and last audit
+#   neuron verify N  — re-verify any past seal against both machines
+#
+# Authority split (by design):
+#   Will seals.  Will can NEVER unseal.
+#   Tim can break-to-read on his machine. Tim can never delete or skip.
+# Deletion is undefined: everything is append-only.
