## Problem

Vehicle signals can aid diagnosis, but research tooling requires a clear boundary before it is used around a live vehicle bus.

## Constraints

- Passive diagnostics only
- No active control claim
- No vehicle identifiers published

## Architecture

- Passive capture
- Signal review
- DBC research
- Diagnostic interpretation

## Decisions

- Observe before changing anything
- Separate research from actuation
- Keep the work passive

## Evidence

- The toolkit is passive diagnostics R&D

## Safety and boundaries

- Listen-only operation
- No active CAN commands
- No vehicle identifiers or connection details

## Stack

- CAN bus
- DBC research
- Passive capture
- Diagnostic workflow

## Safety boundary

Canonical case section: [https://oleksii.almalvs.online/work/chevrolet-volt-toolkit#boundary](https://oleksii.almalvs.online/work/chevrolet-volt-toolkit#boundary)

The toolkit observes and interprets signals only. Actuation, injection and consumer-control claims are outside this research scope.
