+# GovOPlaN Evaluation Codex Guide
+
+## Scope
+
+This repository owns structured questionnaires, rubrics, scoring, aggregation, recurring evaluations, and report-ready evaluation results.
+
+## Documentation Contract
+
+- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
+- Keep feature content here; `govoplan-docs` projects it without importing Evaluation internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.
+
+## Boundaries
+
+- Poll owns lightweight decision and availability polls.
+- Keep Access optional and expose integration through capabilities and typed references.
