This directory contains larger infrastructure platform topics and case studies. Most subdirectories are planning areas unless their own README says otherwise.
Planned platform topics are tracked in [ROADMAP.md](../ROADMAP.md). Keep future additions operational: scope, topology, validation, limitations, and runbook links should matter more than diagrams or buzzwords.
For Codex-driven changes, use [AGENTS.md](../AGENTS.md) and the templates under [docs/codex](../docs/codex/).
