+(a) IS THE OWNER'S GATE, and the spec says so: "a fork that asks before
+applying it is right to ask; a peer's assurance that the owner agreed is NOT
+the owner's word." This seat asked in its own terminal and the owner answered
+there. The sentence is ported VERBATIM from the template — not paraphrased,
+because a standing authorisation that each fork rewords is fourteen different
+authorisations.
+
+Read its second half as carefully as its first: CLAUDE.md is named in its own
+list of things needing the owner's word, so the clause does not pre-authorise
+its own amendment, and push/merge/tag stay behind the owner's word too.
+
+(b) IS A PER-FORK VALUE. `.claude/session-name` holds this host's app key so
+`claude -n "$(cat .claude/session-name)"` starts a session already named for
+the host. Its content is the fork's OWN key — a byte-copy of the template's
+would start every session in the fleet under the template's address.
