A standard is a versioned, owned document that engineering work is checked against — not an informal guideline.
What a standard is
Every standard has an owner, a version, and a status, and is checked against the Master Registry rather than living only in a person's memory.
How standards are categorized
Standards are grouped by discipline — Foundation, Engineering, Architecture, Quality, Delivery and Operations — matching how the Standards page presents them.
Standard status values
A standard is Official once adopted, Frozen when stable and no longer actively revised, or still In Development.
