+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Safe Kiddo Daemon (SKD) is a FastAPI-based service for managing local user accounts on kids' laptops. It provides account locking/unlocking with countdown notifications, optional sound alerts, and shutdown capabilities. The service exposes a REST API with bearer token auth (PAM or OIDC) and serves a minimal web UI.
+
+## Commands
+
+### Development
+```bash
+# Run the service manually (uses .venv, binds to 0.0.0.0:80)
+./scripts/run.sh
+
+# Install service and dependencies
+sudo make install
+
+# Service management
+sudo make up      # Start service
+sudo make down    # Stop service
+sudo make update  # Pull latest from git, reinstall deps, restart
+
+# Generate/set API token
+make token
+
+# Health check (requires token)
+make healthcheck
+```
+
+### Installation & Deployment
+```bash
+# Full install (creates service user, venv, systemd unit, PAM config)
+sudo ./scripts/install.sh
+
+# Deploy to remote host (requires deploy_hosts.yml)
+./scripts/deploy.sh <host-name>
+
+# Manual update on target
+ssh user@target 'cd /opt/sk && ./scripts/update.sh'
+```
+
+### Testing
+```bash
+# Python syntax validation
+python -m py_compile backend/*.py
+
+# Run specific tests (no formal test runner yet; tests/ is empty)
+# Use curl for API testing:
+token=$(curl -s -X POST -H "Content-Type: application/json" \
+  -d '{"username":"root","password":"..."}' \
+  http://localhost/login | jq -r .token)
+curl -H "Authorization: Bearer $token" http://localhost/users
+```
+
+## Architecture
+
+### Core Structure
+- `backend/`: FastAPI application
+  - `app.py`: Main FastAPI app with route handlers
+  - `actions.py`: User management actions (lock/unlock, notifications, shutdown logic)
+  - `auth.py`: PAM authentication, JWT tokens, user/group authorization checks
+  - `oidc.py`: OIDC client (dynamic discovery, token exchange, claims validation)
+  - `update.py`: Update client logic (check/status/logs, triggers async update/rollback scripts)
+  - `settings.py`: Environment-based configuration (Settings class, singleton via lru_cache)
+  - `models.py`: Pydantic models for API requests/responses
+  - `templates/`: Jinja2 templates for web UI
+- `scripts/`: Deployment and lifecycle scripts
+  - `install.sh`: System setup (user, venv, systemd, PAM config)
+  - `run.sh`: Manual service start
+  - `update.sh`: Local git pull and service restart
+  - `update_client.sh`: Full update flow with backup/rollback
+  - `rollback_client.sh`: Restore from backup if update fails
+  - `deploy.sh`: SSH-based deployment to remote hosts
+  - `register_oidc_client.sh`: OIDC dynamic client registration helper
+- `sk.sh`: Legacy bash script (CLI fallback for direct SSH use)
+- `src/`: Hexagonal architecture skeleton (core/ports/adapters/ui) - currently empty placeholders
+- `docs/`: Detailed specs for OIDC validation, update API, status/log formats
+- `Makefile`: Convenience targets for install, service control, updates, token management
+
+### Key Architectural Patterns
+
+**Dual Authentication**: PAM-based local auth (root/sudo users) is always available; OIDC is optional if `SKD_OIDC_ISSUER`, `SKD_OIDC_CLIENT_ID`, and `SKD_OIDC_CLIENT_SECRET` are configured. Both modes issue JWT bearer tokens.
+
+**Settings Management**: All config via environment variables (loaded from `/etc/skd/env` in production). `settings.py` provides a singleton `Settings` instance via `get_settings()` using `lru_cache`. FastAPI dependencies inject settings into route handlers.
+
+**Action Execution**: `actions.py` wraps all privileged operations (usermod, pkill, shutdown) via `_run()` helper. Dry-run mode (`SKD_DRY_RUN=true`) logs commands without executing them.
+
+**Update Flow**: `update.py` checks remote update service for new versions, writes status to JSON files, and triggers async scripts (`update_client.sh`, `rollback_client.sh`) that create backups, apply updates, and handle rollbacks on failure.
+
+**Authorization**: `auth.py` checks both user allowlists (`SKD_AUTH_ALLOWED_USERS`) and group membership (`SKD_AUTH_ALLOWED_GROUPS`, defaults to `sudo`). UID 0 (root) always allowed for PAM. OIDC validates against `preferred_username`, `email`, or `sub` claims.
+
+**Manageable Users**: Only system users with UID >= 1000, real shells (not nologin/false), and optional allowlist (`SKD_ALLOWED_USERS`) are exposed via API. Root accounts are never manageable.
+
+## Configuration
+
+Deployment config lives in `/etc/skd/env` (see `env.example` in repo root):
+- `SKD_AUTH_SECRET`: HMAC secret for JWT signing (must be strong in production)
+- `SKD_AUTH_ALLOWED_USERS`: Comma-separated user allowlist (for login and OIDC claims)
+- `SKD_AUTH_ALLOWED_GROUPS`: Groups whose members may log in (PAM only, default `sudo`)
+- `SKD_AUTH_PAM_SERVICE`: PAM service name (Ubuntu/Debian use `skd`, others may use `login`)
+- `SKD_OIDC_*`: OIDC provider config (ISSUER, CLIENT_ID, CLIENT_SECRET, REDIRECT_URI, SCOPES)
+- `SKD_ALLOWED_USERS`: Comma-separated list of manageable system accounts (optional)
+- `SKD_DRY_RUN`: If `true`, logs all privileged commands without executing
+- `SKD_UPDATE_*`: Update service URL, token, interval, status/log file paths
+
+## Important Workflows
+
+### Disable User Flow
+1. API call to `/users/{username}/disable` with optional `{countdown, sound, message}`
+2. `actions.disable_user()` locks account via `usermod -L`
+3. If user logged in: sends desktop notifications, plays sound (if enabled), countdown loop with periodic reminders
+4. Terminates sessions via `pkill -KILL -u`
+5. Triggers `shutdown now` only if user was logged in
+
+### OIDC Login Flow
+1. User accesses `/login/oidc/start` → redirected to provider with state cookie
+2. Provider redirects to `/login/oidc/callback` with code + state
+3. Validates state, exchanges code for tokens, extracts username from claims
+4. Issues JWT session cookie if user in allowlist
+
+### Update Flow
+1. `check_update()` polls remote update service for latest manifest (version, artifact_url, sha256)
+2. `start_update()` writes "in_progress" status, launches `update_client.sh` in background
+3. Script creates backup, downloads artifact, verifies checksum, installs, restarts service
+4. On failure: `rollback_client.sh` restores from backup
+5. Status/logs written to JSON files at `SKD_UPDATE_STATUS_FILE` and `SKD_UPDATE_LOG_FILE`
+
+## Security Considerations
+
+- Service runs as root by default (required for PAM, usermod, pkill, shutdown). Limit exposure via firewall.
+- Set strong `SKD_AUTH_SECRET` and rotate by changing value + restarting service.
+- Restrict API/Web UI to LAN/VPN; consider mTLS or IP allowlisting.
+- `skd` user/group created by install script; consider sudoers rules to limit privileges to specific commands.
+- OIDC redirect URI must match exactly (no wildcards); re-register client if host/port changes.
+- Validate TLS certificates in production; self-signed certs require CA trust or fallback to PAM.
+
+## Notes
+
+- Legacy `sk.sh` remains for emergency CLI fallback; API is preferred for all operations.
+- `src/` hexagonal architecture skeleton is currently unused; logic lives in `backend/`.
+- `tests/` directory exists but is empty; use manual curl-based API testing.
+- Both German and English comments exist in code; favor English going forward.
+- Deployment via `deploy.sh` supports both YAML (`deploy_hosts.yml`) and JSON host configs.
+- PAM service file (`/etc/pam.d/skd`) created by `scripts/install.sh` on Ubuntu/Debian; other distros may need manual setup.

+
+# Admin Token Operations
+
+## Purpose
+This document describes how operators create and manage pre-shared enrollment tokens for clients.
+
+## Pre-Shared Token Creation
+Operators generate a single-use enrollment token and share it out-of-band with the client.
+
+Recommended properties:
+- Single-use only
+- Short TTL (e.g., 24h)
+- Scoped to `project_id` and optional `client_id`/`software_id`
+
+## Admin Interfaces
+We provide both an Admin API and a CLI tool for token operations. A frontend will be added later.
+
+### Admin User and Access
+- An admin user must exist to operate token workflows.
+- Initial access uses a local admin token.
+- Later, admin auth will be integrated with the OIDC service.
+
+### CLI and Admin API Capabilities
+- Create enrollment tokens
+- List token metadata (no plaintext output)
+- Revoke tokens
+- Export a token as a file for client installation
+
+### Local Admin Token (Initial Phase)
+- Admin requests must include `Authorization: Bearer <ADMIN_TOKEN>`.
+- The admin token is stored locally (e.g., `.env`) and never committed.
+
+Example `.env` (local only):
+```
+ADMIN_TOKEN=change-me-please
+```
+
+Minimal flow (first token):
+1) Set `ADMIN_TOKEN` in `.env`.
+2) Call `POST /v1/admin/enrollment-tokens` with the bearer token.
+3) Export the returned one-time token to a file and hand it to the client.
+
+## Admin API (Draft)
+All admin endpoints are authenticated. Initial auth is local; later OIDC.
+
+Base path:
+- `/v1/admin`
+
+Endpoints:
+- `POST /v1/admin/enrollment-tokens`
+  - Create a pre-shared enrollment token.
+  - Request: `project_id`, optional `client_id`, optional `software_id`, optional `expires_at`.
+  - Response: token metadata + one-time plaintext token.
+- `GET /v1/admin/enrollment-tokens`
+  - List token metadata (never return plaintext tokens).
+  - Supports filtering by `project_id`, `client_id`, `status` (active/used/expired).
+- `POST /v1/admin/enrollment-tokens/{token_id}/revoke`
+  - Revoke a token (marks as revoked or sets `used_at`/`revoked_at`).
+- `GET /v1/admin/enrollment-tokens/{token_id}/export`
+  - Export the one-time token to a file download (single use).
+
+## CLI (Draft)
+Example commands (names can be adjusted):
+- `update-service admin token create --project <id> [--client <id>] [--software <id>] [--expires <iso8601>]`
+- `update-service admin token list --project <id> [--status active|used|expired|revoked]`
+- `update-service admin token revoke --id <token_id>`
+- `update-service admin token export --id <token_id> --out ./enroll-token.txt`
+
+Example format:
+```
+enroll_<random_32_bytes>
+```
+
+## Storage and Safety
+- Store only a hash of the enrollment token (never plaintext).
+- Track `created_at`, `expires_at`, and `used_at`.
+- Deny enrollment if `expires_at` is exceeded or `used_at` is set.
+
+## Rotation and Revocation
+- Revoke enrollment tokens by invalidating their stored hash.
+- Issue a new enrollment token if the previous one expires or is leaked.
+
+## Distribution
+Preferred channels:
+- One-time install code (copy/paste)
+- QR code
+- Encrypted file included in an install bundle
+
+## Audit Expectations
+- Log token creation and enrollment usage for traceability.

+# Client Quickstart
+
+## Goal
+Enroll a client, store the long-term token, fetch the manifest, and report status.
+
+## 1) Get a Pre-Shared Token
+Request a one-time enrollment token from an admin/operator.
+
+## 2) Enroll and Receive Long-Term Token
+```
+curl -X POST https://update.wlkns.org/v1/enroll \
+  -H "Content-Type: application/json" \
+  -d '{
+    "project_id": "safe-kiddo-control",
+    "client_id": "kiddo-001",
+    "software_id": "kiddo-agent",
+    "enroll_token": "<pre_shared_token>"
+  }'
+```
+
+Store the returned token locally (file or secret store). Example:
+```
+echo "<long_term_token>" > ./update-token.txt
+```
+
+## 3) Fetch Manifest
+```
+curl -H "Authorization: Bearer $(cat ./update-token.txt)" \
+  https://update.wlkns.org/v1/projects/safe-kiddo-control/manifest
+```
+
+## 4) Report Status
+```
+curl -H "Authorization: Bearer $(cat ./update-token.txt)" \
+  -H "Content-Type: application/json" \
+  -d '{"project_id":"safe-kiddo-control","version":"0.1.2","status":"success","timestamp":"2025-12-30T10:00:00Z"}' \
+  https://update.wlkns.org/v1/projects/safe-kiddo-control/status
+```
+
+## Notes
+- All endpoints require `Authorization: Bearer <token>` except `/v1/enroll`.
+- Status values: `success`, `failed`, `in_progress`.

+
+# Third-Party API Guide
+
+## Purpose
+This document explains how third-party services integrate with the Update Webservice: obtaining tokens, fetching manifests, downloading artifacts, and reporting status.
+
+## Quick Start (First Client)
+1) Request a pre-shared enrollment token from an admin/operator.  
+2) Enroll once to obtain a long-term token.  
+3) Store the long-term token locally and use it for all API calls.  
+
+## Base URLs
+- Production: `https://update.wlkns.org`
+- Staging: `https://staging.update.wlkns.org`
+
+All endpoints are versioned under `/v1`.
+
+## Authentication
+All endpoints require `Authorization: Bearer <token>`.
+
+### Enrollment (Pre-Shared Token -> Long-Term Token)
+Clients obtain a long-term token by exchanging a pre-shared token provided by an admin/operator.
+
+Request (example):
+```
+POST /v1/enroll
+{
+  "project_id": "<project>",
+  "client_id": "<client>",
+  "software_id": "<software>",
+  "enroll_token": "<pre_shared_token>"
+}
+```
+
+Response (example):
+```
+200 OK
+{
+  "token": "<long_term_token>",
+  "scope": "read_manifest report_status",
+  "expires_at": "<iso8601 or null>"
+}
+```
+
+Notes:
+- Enrollment tokens are single-use and must be invalidated after a successful exchange.
+- If the token is invalid or reused, the server responds with `unauthorized` or `invalid_payload`.
+- Enrollment does not require an existing bearer token.
+ - If the client is already enrolled, the server responds with `already_enrolled` (HTTP 409).
+
+## Client API (Read + Report)
+
+### Get Manifest
+```
+GET /v1/projects/{project_id}/manifest
+```
+
+Response:

+  "sha256": "<hex>",
+  "sig_url": "<optional>"
+}
+```
+
+Required scope: `read_manifest`
+
+### Download Artifact

+{
+  "project_id": "<project_id>",
+  "version": "<semver>",
+  "status": "success|failed|in_progress",
+  "timestamp": "<iso8601>",
+  "client_id": "<optional>",
+  "duration_ms": "<optional>",
+  "error_code": "<optional>"
+}
+```
+
+Required scope: `report_status`
+
+## Release API (Upload)
+
+### Upload Release
+```
+POST /v1/projects/{project_id}/releases
+Content-Type: multipart/form-data
+```
+
+Required scope: `upload_release`
+
+Required fields:
+- `version` (SemVer)
+- `artifact` (file)
+- `sha256` (hex)
+
+Optional fields:
+- `sig_url` or inline signature
+- `key_id`
+
+## Error Codes
+Common error codes:
+`unauthorized`, `rate_limited`, `not_found`, `invalid_payload`, `version_invalid`,
+`version_exists`, `checksum_mismatch`, `signature_missing`, `signature_invalid`,
+`payload_too_large`, `status_invalid`
+
+## Rate Limits
+Limits are tiered by scope. See `docs/architecture/ARCHITECTURE.md` for current values.
+
+## Examples
+Fetch manifest:
+```
+curl -H "Authorization: Bearer $TOKEN" \
+  https://update.wlkns.org/v1/projects/$PROJECT_ID/manifest
+```
+
+Report status:
+```
+curl -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"project_id":"'"$PROJECT_ID"'","version":"0.1.2","status":"success","timestamp":"2025-12-30T10:00:00Z"}' \
+  https://update.wlkns.org/v1/projects/$PROJECT_ID/status

+# Client Update Flow (Kiddo)
+
+## Purpose
+Definiert den Client-seitigen Ablauf fuer das Pull-Update vom Update-Service.
+
+## Manifest Format (JSON)
+Beispiel:
+```json
+{
+  "version": "0.1.2",
+  "artifact_url": "https://update.wlkns.org/kiddo/kiddo-0.1.2.tar.gz",
+  "sha256": "<hex>",
+  "sig_url": "https://update.wlkns.org/kiddo/kiddo-0.1.2.sig"
+}
+```
+
+## Flow (High Level)
+1. Manifest abrufen (auth optional via Bearer Token).
+2. `artifact_url` herunterladen.
+3. SHA256 pruefen (Signatur optional).
+4. In Staging-Verzeichnis entpacken.
+5. Service stoppen.
+6. Atomic swap: aktuelles Verzeichnis sichern, Staging nach `/opt/sk` verschieben.
+7. Service starten.
+8. Bei Fehlern Rollback auf Backup.
+
+## Prototype Script
+- `scripts/update_client.sh` implementiert den Flow als CLI-Prototyp.
+- Erfordert `curl`, `tar`, `sha256sum`, `python3` und `systemctl`.
+
+## Rollback
+- Wenn Start fehlschlaegt: Backup nach `/opt/sk` zurueck, Service neu starten.
+- Backup-Verzeichnis benoetigt genuegend Speicher.
+
+## Security Notes
+- Artefakte muessen checksum-verifiziert sein.
+- Token-Handling ueber `SKD_UPDATE_TOKEN`.
+
+## Constraints
+- Update-Service ist extern (update.wlkns.org).
+- Service muss als root stoppen/starten koennen.
+
+## Status Reporting
+- Status wird per HTTP POST an `https://update.wlkns.org/status` gemeldet.
+- Schema siehe `docs/update-status.md`.
+- Lokaler Status/Logs liegen unter `/var/lib/skd` (konfigurierbar via ENV).

+# EPIC_000010: Update-Service v1 Migration (Major Release)
+
+## Beschreibung
+Migration des Update-Clients auf den neuen v1 Update-Service mit verpflichtender Authentifizierung
+und Enrollment-Flow fuer Langzeit-Tokens. Diese Umstellung ist ein Major Release.
+
+## Ziel / Business Value
+Sicheres, standardisiertes Update-Management mit verpflichtender Auth und nachvollziehbarem Status-Reporting.
+
+## Mission Statement
+Stelle sicher, dass der Client die v1 Endpunkte nutzen kann, inkl. Enrollment und
+neuem Status-Schema.
+
+## Business Value & Metriken
+- Security: Auth ist obligatorisch fuer alle Requests.
+- Erfolgsmetrik: 100% der Clients koennen per v1 manifest/artifact/status arbeiten.
+
+## In-Scope (Kiddo Team)
+- Enrollment-Flow fuer Langzeit-Token (mit Pre-Shared Token).
+- Update-Client auf v1 Endpunkte umstellen.
+- Status-Payload auf v1 Schema umstellen.
+- Migration-Notiz/Docs fuer Client-Dev.
+
+## Out-of-Scope
+- Betrieb/Hosting des Update-Services.
+- Ausgabe/Verwaltung von Pre-Shared Tokens auf Server-Seite.
+
+## High-Level Akzeptanzkriterien
+- Auth ist Pflicht (Bearer Token) fuer Manifest, Artifact und Status.
+- Enrollment liefert Langzeit-Token, der lokal gespeichert wird.
+- v1 Endpunkte werden genutzt:
+  - GET /v1/projects/{project_id}/manifest
+  - GET /v1/projects/{project_id}/releases/{version}/artifact
+  - POST /v1/projects/{project_id}/status
+
+## Technische Constraints & Risiken
+- Major Release: Rollout-Strategie und Backward Compatibility klaeren.
+- Token-Handling und sichere lokale Speicherung.
+
+## Zugeordnete User Stories
+- US_000034: Enrollment fuer Langzeit-Token
