Lab: Capture Description Workbook

The capture-description workbook lives at samples/capture-description-workbook/. It contains synthetic passive text records for candump-style and ASC-style Classical CAN evidence, plus a small DBC authority artifact and metadata summary.

The lab is for offline inspection. It does not define live capture setup, hardware configuration, replay steps, or transmit helpers. Its purpose is to separate observed log-record evidence from recorded CAN-frame fields and from DBC-based signal meaning.

Use the repository files directly:

  • samples/capture-description-workbook/README.md
  • samples/capture-description-workbook/manifest.yml
  • samples/capture-description-workbook/raw/
  • samples/capture-description-workbook/expected/

Bounded Exercise

Compare the candump-style and ASC-style records with their expected files, then inspect the synthetic DBC separately:

  1. List only the timestamp, channel or interface token, identifier, and payload fields directly represented by each text record.
  2. Identify which direction token is capture-format evidence rather than an instruction or proof of physical direction.
  3. Explain which decoded signal claims come from the DBC and why the DBC's provenance remains part of those claims.

Conclude with one ambiguity that survives a structurally valid parse. The exercise is offline description analysis; it does not add live capture, replay, or transmission steps.
