+# GovOPlaN Organizations Codex Guide
+
+## Scope
+
+This repository owns the canonical GovOPlaN organizational model: tenant-local
+organization units, hierarchy, functions, and account-held function
+assignments.
+
+The module describes responsibility in the institution. It does not decide
+which rights those responsibilities grant; `govoplan-access` maps organization
+facts to roles, rights, permission decisions, and explainability.
+
+## Boundaries
+
+- Depend on kernel contracts from `govoplan-core`.
+- Depend on `govoplan-tenancy` for tenant ownership.
+- Do not import access, identity, postbox, workflow, or portal internals.
+- Expose integration through manifests, capabilities, API routes, events, and
+  typed DTOs.
+- Treat function assignment as organizational responsibility, not as a login
+  permission by itself.
+
+## Local Workflow
+
+Use Gitea issues as the canonical backlog and state log. The shared workflow is
+installed under `.gitea/`, with labels in `docs/gitea-labels.json`.
+
+Focused verification is still driven from `/mnt/DATA/git/govoplan-core` for
+cross-repository behavior.
