+# exec-sign.sh — call the bl exec-constrained server with SSH-signature auth.
+# No bearer token, no secret crosses the wire: you sign the request envelope
+# with your registered fleet key and the server verifies it against the
+# signers file. A signature is not a secret, so this never trips
+# secret-handling guardrails.
+#
+# Server: exec-constrained.py — named ops ONLY, no arbitrary shell.
+# Signature namespace: exec-constrained
+# Envelope: {"op","args","ts","nonce"} — op must be in the server allowlist:
+#   dm.send, dm.thread, dm.read, job.run, chat.messages, chat.send,
+#   health.check, exec.ping
+# Nonce: 16+ hex chars, replay-protected server-side. ts: unix epoch, ±300s skew.
+#
+# Usage: exec-sign.sh <op> '<args-json>' [identity] [keyfile] [url]
+#   op         a named op, e.g. exec.ping
+#   args-json  JSON object of the op's arguments, e.g. '{}'
+#   identity   defaults to operator-646 (must be a principal in the
+#              server's signers file)
+#   keyfile    defaults to ~/.ssh/id_frontdoor
+#   url        defaults to https://exec.muse-dev.online/exec (cloudflared).
+#              NOTE: the old VM Caddy /exec route to bl:8443 died with
+#              exec-server.py — do not point this at the sslip.io URL.
