Traceability

Direct Evidence

  • Legacy ADR: docs/architecture/Architecture-Decision-Records/ADR-001-Communication.md
  • IGB-COM-001_Communication_Architecture.md
  • Repository file exists.
  • Current content: empty.
  • No historical decision content identified.
  • IGB-ADR-002
  • GPIO-25 is independently recorded as Emergency SOS.
  • This relationship does not establish the implementation mechanism of the Emergency SOS Override decision in this ADR.
