CLAUDE.md gained the admin-only note when the key joined claude's privilegedEnvKeys;
architecture-invariants, which is where the exact-key allowlist rule is documented in
depth, still described the pre-change world. The reboot-restore half is the one worth
writing down: a non-granted owner's already-persisted CLAUDE_CONFIG_DIR is stripped on
restore, which moves that session back to the default Claude account with no error.
