Research: Platform Convergence C3

Objective

Define state 012 as a C3 convergence checkpoint on top of state 011 without introducing new runtime behavior.

Inputs Reviewed

• spec.md
• plan.md
• tasks.md
• system/architecture.md
• system/runtime-topology.md

Key Decisions

1. Reuse the complete runtime and functional baseline from state 011.
2. Keep convergence as metadata/documentation, not a runtime fork.
3. Preserve functional behavior and external API expectations from predecessor state.
