SES-NODETEST-20260901T140000Z
Synthetic record bundle for the Systems watch problem. No real operating data, no positions.

Structure
  manifest.json      what this bundle claims about itself: node, asset, session window, files, checksums
  imu.csv            motion at 1 Hz: raw accelerations (g) and rates (deg/s), with derived roll and pitch (deg)
  env.csv            environment every 60 s
  power.csv          power every 60 s
  health.jsonl       one event per line: boot, heartbeat, sensor checks, and anything the node needs to declare
  checksums.sha256   the same checksums as manifest.json, in sha256sum format

Validate offline
  shasum -a 256 -c checksums.sha256      (or: sha256sum -c checksums.sha256)
Every claim the bundle makes about itself should be checkable with that command and a text editor.

Conventions
  All timestamps are UTC, ISO 8601, second resolution. Records are append-only and in order of capture.
  Calibration for this node is recorded under the calibration identifier in manifest.json.
