Embedded Traceability
=====================

This local traceability register connects the Embedded intended-behavior pages
to the requirements baseline.  Entries are deliberately medium-granularity so
that each behavior can be reviewed against firmware later without treating
implementation as the source of truth.

hardware electrical limits, and evidence retention rules.  These remain
``Not In Docs`` until the responsible section defines them.
