This adds a one-page summary of the current REV004 mainline delivery state,
including merged backend/docs commits, object truth status, evidence anchors,
and remaining external blockers.
Constraint: Summary must reflect verified mainline truth only, not feature-branch intent
Rejected: Scatter this information across multiple historical evidence files | too costly for frontline consumers to reconstruct delivery status
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep this summary as the top-level operator handoff page and refresh only after meaningful mainline state changes
Tested: Cross-checked against origin/develop and origin/main latest merge commits plus existing evidence set
Not-tested: No document export/render pipeline executed for this summary
