 # install-larry.sh — bootstrap Larry-Anywhere on a fresh remote shell.
 # No root, no package install, no sudo. Writes only into $LARRY_HOME.

+# Usage (v0.9.8+ — ONE-ARG self-contained broker install, Bryan-approved 2026-07-09):
+#   curl -fsSL <BASE_URL>/install-larry.sh | bash -s <client-id>
+#     Self-enrolls against the broker using ONLY the client-id — no manual env
+#     vars, no secret to paste. The broker (which the box owner already
+#     provisioned with `provision_broker_client.sh <dep-id> --open-enroll
+#     <client-id>`) hands back the deployment-id + a fresh enrollment secret
+#     ONCE. A second run of the same client-id fails replay-safe (the broker
+#     returns 409 already_enrolled) — that is BY DESIGN, not a bug; the trust
+#     boundary is the single admin-opened claim window, closed either by the
+#     first successful claim or by the kill-switch (broker_ctl set-authorized
+#     <dep-id> false). See "ONE-ARG SELF-ENROLL" below.
+#
+#   curl -fsSL <BASE_URL>/install-larry.sh | bash -s -- --uninstall [flags]
+#     Fetches uninstall-larry.sh fresh and runs it (dry-run by default, same
+#     as running it directly — pass --yes to actually delete). See its own
+#     --help for --keep-data / --keep-rc / --no-shred.
