v5.1.0 shipped with an unquoted brief_version: 2.1 in trekbrief-template.md.
parseScalar coerced it to Number 2.1, and the sequencing gate guarded on
typeof === 'string', silently bypassing BRIEF_V51_MISSING_SIGNALS.
Three-part atomic fix:
- brief-validator.mjs:87+149 now accepts both string and number forms via
String(fm.brief_version) coercion.
- trekbrief-template.md quotes the value so new briefs parse as String.
- doc-consistency.test.mjs pins the QUOTED form going forward.
Three regression tests added in brief-validator.test.mjs.
