# SP CLI — Signal__Codec
# Encode/decode the x-sentinel-signal envelope. The wire form is a raw compact JSON
# string (no base64 — CloudFront Functions lack Buffer/btoa). decode() validates by
# construction into Schema__Sentinel__Signal; extra captured keys (request_id,
# aws_request_id) the JS nests are ignored on the way in.
