Slate v2 Roadmap Final Follow-On

Supporting plan. For current queue and roadmap truth, see master-roadmap.md.

Goal

• Do one last evidence pass on the roadmap stack and only edit docs if a real inconsistency remains.

Phases

• Check existing learnings and critical patterns
• Audit the active roadmap docs for remaining drift
• Patch only a material gap
• Verify edited docs

Finding

• The closeout docs already said roadmap grooming was no longer the default queue, but several active docs still framed Phase 10 as the current active queue. That was a real contradiction, not copy polish.

Patch

• Align the active docs around one read:
  • the Phase 10 release-readiness stack is coherent enough to stop default roadmap work
  • default next work is implementation or shipping
  • roadmap follow-on is selective only when it changes the claim
