+# GovOPlaN Files Codex Guide
+
+## Scope
+
+This repository owns the `files` module: managed file storage APIs, file metadata, shares, uploads/downloads, folder and pattern helpers, backend module manifest, and `@govoplan/files-webui`.
+
+Core owns auth, tenants, RBAC, database/session primitives, CSRF/API helpers, shared components, and shell layout. Campaign integration must remain optional and go through core module metadata or capabilities.
+
+## Local Commands
+
+Install and run through core:
+
+```bash
+cd /mnt/DATA/git/govoplan-core
+./.venv/bin/python -m pip install -r requirements-dev.txt
+```
+
+For combined checks, run:
+
+```bash
+cd /mnt/DATA/git/govoplan-core
+./scripts/check-focused.sh
+```
+
+For WebUI permutation checks that include files:
+
+```bash
+cd /mnt/DATA/git/govoplan-core/webui
+PATH=/mnt/DATA/git/govoplan-core/webui/node_modules/.bin:/home/zemion/.nvm/versions/node/v22.22.3/bin:$PATH /home/zemion/.nvm/versions/node/v22.22.3/bin/npm run test:module-permutations
+```
+
+## Working Rules
+
+- Keep files behavior in this module, not core.
+- Do not require campaign or mail imports for files-only startup.
+- Shared WebUI components belong in core; files WebUI should consume them through `@govoplan/core-webui`.
+- Preserve optional campaign usage tracking through capability/registry boundaries.
