The 13:19:41Z refusal on PC 2: fetch_jobs took igneum-jobs.json and .sig in two requests while the edge was
still serving the previous deployment for one of them. The signer wraps the verified pair into one object and
reads it back; the app fetches that object (the pair only when none is published); publish-jobs.sh writes and
mirrors all three files and verifies every folder after the deploy; tools/jobs.mjs reads the envelope.
Tests: jobs.rs signed_envelope_binds_file_and_signature, packaging/ota/test-publish-jobs.sh (24 checks).
