feat: secure build phase 1 — cosign cell-side image verification (warn default) + Dockerfile validation

- config/cosign/cosign.pub: public verification key committed to repo (safe);
  cosign private key lives in /home/roof/.pic-secrets/ and is NEVER committed
- api/config_manager.py: image_verification config block (modes: off|warn|enforce,
  default: warn) so existing deployments are unaffected until images are signed
- api/service_composer.py: cosign verify before pull/up; enforce aborts the
  operation, warn logs and proceeds, off skips entirely; also fixes the prior
  unsafe proceed-on-pull-failure path
- api/service_store_manager.py: store-image digest requirement (warn default,
  reject under enforce)
- api/Dockerfile: cosign binary copied from the official cosign image
- docker-compose.yml: config/cosign/ bind-mounted into cell-api container
- install.sh: ensure/verify bundled cosign pubkey on new cell installs
- api/manifest_validator.py: validate_build_context() — Dockerfile lint
- tests: full coverage for config modes, composer verify paths, store digest
  guard, and validate_build_context

Verification defaults to warn so nothing breaks in production until images are
signed (phase 2). Private key stored outside git at /home/roof/.pic-secrets/.

-## What This Project Is
+---
 
-**Personal Internet Cell (PIC)** — a self-hosted digital infrastructure platform. It manages DNS, DHCP, NTP, WireGuard VPN, email, calendar/contacts (CalDAV), file storage (WebDAV), reverse proxy (Caddy), a certificate authority, and container orchestration, all from a single API + React UI.
+## Project Overview
 
-## Common Commands
+**Personal Internet Cell (PIC)** is a self-hosted digital infrastructure platform for individuals who want full ownership of their core internet services without relying on cloud providers.
 
-```bash
-# Full stack
-make start          # docker-compose up -d
-make stop           # docker-compose down
-make restart        # docker-compose restart
-make status         # docker status + API health
-make logs           # docker-compose logs -f
-make build          # rebuild api image
+A PIC instance runs DNS, NTP, WireGuard VPN, an HTTPS reverse proxy (Caddy), an internal certificate authority, and — as optional store services — email (SMTP/IMAP), calendar/contacts (CalDAV/CardDAV), file storage (WebDAV), and extended-connectivity exits (WireGuard-ext, OpenVPN, Tor, sshuttle, proxy) — all managed from a single REST API and a React web UI. No manual config-file editing is required for normal operations.
 
-# Tests
-make test           # pytest tests/ api/tests/
-make test-coverage  # pytest with coverage HTML report
-make test-api       # pytest tests/test_api_endpoints.py
-pytest tests/test_<module>.py   # single test file
+**Primary users:** technically capable individuals, homelab operators, small families or teams.
 
-# Local dev (no Docker)
-pip install -r api/requirements.txt
-python api/app.py                 # Flask API on :3000
+**What the product optimizes for:**
+- One-command install, browser-based first-run wizard, no manual `.env` editing for identity
+- Everything managed through the API and UI — the user should never need to `ssh` for day-to-day operations
+- Security by default: session auth, CSRF protection, WireGuard isolation, internal CA, no open API port
+- Reliability and observability: structured logs, health monitoring, automated config backups
 
-cd webui && npm install && npm run dev   # React UI on :5173 (proxies API to :3000)
+**Key constraints:**
+- Runs on a single Linux host with Docker; no Kubernetes, no swarm
+- Must work on Debian, Ubuntu, Fedora, RHEL, and Alpine
+- The Flask API must never be exposed directly; Caddy always proxies it
+- All secrets live in `data/` (git-ignored), never in the repo
 
-# WireGuard
-make show-routes
-make add-peer PEER_NAME=foo PEER_IP=10.0.0.5 PEER_KEY=<pubkey>
-make list-peers

-All service managers inherit `BaseServiceManager` (`api/base_service_manager.py`). This enforces a consistent interface: `get_status()`, `get_config()`, `update_config()`, `validate_config()`, `test_connectivity()`, `get_logs()`, `restart_service()`. When adding or modifying a service manager, follow this pattern.
+### Key files
 
-The `ServiceBus` (`api/service_bus.py`) is a pub/sub event system used for inter-service communication. Services publish events (e.g., `SERVICE_STARTED`, `CONFIG_CHANGED`, `PEER_CONNECTED`) and subscribe to events from dependencies. Dependency graph is declared in the bus — e.g., `wireguard` depends on `network`; `email` depends on `network` and `vault`.
+| File | Role |
+|---|---|
+| `api/app.py` | Flask app, all REST endpoints, before-request hooks, health monitor thread |
+| `api/managers.py` | Singleton instantiation of all service managers |
+| `api/base_service_manager.py` | Abstract base class: `get_status`, `get_config`, `update_config`, `validate_config`, `test_connectivity`, `get_logs`, `restart_service` |
+| `api/config_manager.py` | Single source of truth for `cell_config.json` — all read/write goes through here |
+| `api/service_bus.py` | Pub/sub event system between managers |
+| `webui/src/services/api.js` | Axios API client — all UI→API calls |
+| `docker-compose.yml` | Container definitions and network topology |
+| `Makefile` | All operational commands |
+| `install.sh` | Bash installer served via `https://install.pic.ngo` |
 
-`ConfigManager` (`api/config_manager.py`) is the single source of truth. Config lives in `/app/config/cell_config.json` (mapped from `config/api/`). All managers read/write through ConfigManager, which validates against per-service schemas and maintains automatic backups.
+### Directory layout
 
-`LogManager` (`api/log_manager.py`) provides structured JSON logging with rotation (5 MB / 5 backups per service). Use it instead of `print()` or raw `logging`.
+```
+api/           Flask API and all service managers
+webui/         React SPA (Vite + Tailwind)
+tests/         pytest unit tests (no running services required)
+tests/integration/  require a running PIC stack
+tests/e2e/     Playwright UI and WireGuard e2e tests
+config/        Runtime config per service (mostly git-ignored)
+data/          Runtime secrets and state (fully git-ignored)
+scripts/       Setup and maintenance scripts
+install.sh     One-line installer entry point
+Makefile       All make targets
+docker-compose.yml
+```
 
-`app.py` (2000+ lines) contains all Flask REST endpoints, organized by service. It runs a background health-monitoring thread.
+### Config and secrets
 
-Service managers:
-- `network_manager.py` — DNS (CoreDNS), DHCP (dnsmasq), NTP (chrony)
-- `wireguard_manager.py` — VPN peer lifecycle, QR codes
-- `peer_registry.py` — peer registration/lookup
-- `routing_manager.py` — NAT, firewall rules, VPN gateway
-- `vault_manager.py` — internal certificate authority
-- `email_manager.py` — Postfix + Dovecot
-- `calendar_manager.py` — Radicale CalDAV/CardDAV
-- `file_manager.py` — WebDAV storage
-- `container_manager.py` — Docker SDK wrappers
-- `cell_manager.py` — top-level orchestration
+- Runtime config: `config/api/cell_config.json` — managed by `ConfigManager`, never edit directly
+- Secrets and user data: `data/` — git-ignored, contains `auth_users.json`, WireGuard keys, DDNS token, CA key
+- DDNS config lives under the top-level `ddns` key in `cell_config.json`, accessed via `config_manager.configs.get('ddns', {})`
+- Do not read `_identity.domain` expecting a dict — it is a plain string (the domain mode, e.g. `"pic_ngo"`)
 
-### Frontend (`webui/`)
+### Before-request hooks (app.py)
 
-React 18 + Vite + Tailwind CSS. All API calls go through `src/services/api.js` (Axios). Vite dev server proxies `/api` to `localhost:3000`. Pages in `src/pages/`, shared components in `src/components/`.
+Three hooks run on every request in this order:
+1. `enforce_setup` — returns 428 for all `/api/*` except `/api/setup/*` and `/health` until setup is complete. Skipped when `app.config['TESTING']` is True.
+2. `enforce_auth` — returns 401 if no session; returns 503 if users file exists but is empty (misconfiguration). Skipped when `app.config['TESTING']` is True.
+3. `check_csrf` — requires `X-CSRF-Token` header on all mutating requests except `/api/auth/*` and `/api/setup/*`.
 
-### Infrastructure
+---
 
-`docker-compose.yml` defines 13 services on a custom bridge network `cell-network` (172.20.0.0/16). Cell IPs default to 10.0.0.0/24. Key ports: 53 (DNS), 80/443 (Caddy), 3000 (API), 5173/8081 (WebUI), 51820/udp (WireGuard), 25/587/993 (mail), 5232 (CalDAV), 8080 (WebDAV).
+## Coding Conventions
 
-Config files for each service live under `config/<service>/`. Persistent data is under `data/` (git-ignored). WireGuard configs are also git-ignored.
+### Python (API)
 
-## Testing
+- All managers inherit `BaseServiceManager` — always implement all abstract methods
+- Use `self.logger` (from `BaseServiceManager`) — never `print()` or raw `logging`
+- Config reads go through `self.config_manager` — never open `cell_config.json` directly
+- Use `threading.RLock` for shared state; managers run in a multi-threaded Flask app
+- Do not use `any` typing; be explicit
+- Keep Flask route handlers thin — business logic belongs in the manager, not in `app.py`
+- Error responses must be JSON: `jsonify({'error': '...'}), <status_code>`
+- Do not catch bare `Exception` and silently swallow it — log at minimum
 
-Tests live in `tests/` (28 files). Use mocking (`pytest-mock`) for external system calls. Integration tests in `test_integration.py` require Docker services running.
+### JavaScript (webui)
 
-## AI Collaboration Rules (Claude Code)
+- All API calls go through `src/services/api.js` — never use `fetch` or a new Axios instance directly
+- Use functional components; no class components
+- Tailwind utilities only — no inline styles, no custom CSS files
+- Keep page components in `src/pages/`, reusable UI in `src/components/`
+- State: local `useState`/`useEffect` is fine; no Redux or global state library
+
+### General
+
+- No comments that describe *what* the code does — only *why* if non-obvious
+- No dead code, no commented-out blocks
+- No backwards-compat shims for things being removed
+- Prefer editing existing files over creating new ones
+- Tests that write to disk: mock `builtins.open` with `OSError` rather than relying on `/nonexistent/path` (CI runs as root and can create any path)
+
+---
+
+## Testing and Quality
+
+Before considering any task complete:
+1. Run `make test` — all 1500+ unit tests must pass
+2. Fix failures before committing — the pre-commit hook will block the commit anyway
+
+### Rules
+
+- Use `unittest.mock` / `pytest-mock` for all Docker, filesystem, and subprocess calls
+- Tests must pass in CI (rootless environment where filesystem assumptions don't hold)
+- When testing write-failure paths, mock `builtins.open` with `side_effect=OSError` — do not rely on unwritable paths
+- Integration tests (`tests/integration/`) require a running stack — exclude from CI with `--ignore=tests/integration`
+- E2e tests (`tests/e2e/`) require Playwright — exclude from CI with `--ignore=tests/e2e`
+- Add tests for any new API endpoint, manager method, or utility function
+- Do not add tests for Flask routing boilerplate or trivial getters — test behaviour, not structure
+
+---
+
+## File Placement Rules
+
+| New thing | Where it goes |
+|---|---|
+| New service manager | `api/<name>_manager.py`, registered in `api/managers.py` and wired into `app.py` |
+| New API endpoints | `app.py` — grouped with the relevant manager's existing endpoints |
+| New React page | `webui/src/pages/` |
+| Reusable UI component | `webui/src/components/` |
+| New pytest test file | `tests/test_<module>.py` |
+| Operational script | `scripts/` |
+| Documentation | Update `README.md`, `QUICKSTART.md`, or `Personal Internet Cell – Project Wiki.md` as appropriate |
+
+Do not create a new abstraction for a single use case. Do not create near-duplicate files — edit the existing one.
+
+---
+
+## Safety Rules
+
+- **Never expose the Flask API port (3000) directly** — it must always be behind Caddy
+- **Never commit secrets** — `data/`, `.env`, `*.key`, `*.pem` are all git-ignored; keep it that way
+- **Do not modify `enforce_setup` or `enforce_auth` hooks** without understanding the full auth flow — these are the security boundary
+- **Do not change the `cell_config.json` schema** without updating `ConfigManager` validation and all manager reads
+- **Do not rename API route paths** without checking the webui `api.js` client and any external callers
+- **Do not modify WireGuard key generation** — losing the server private key means all peers must be re-provisioned
+- Flag any change to auth flow, CSRF logic, or session management as security-sensitive before implementing

+## Infrastructure Topology
+
+| Machine | IP | Role |
+|---|---|---|
+| pic0 | 192.168.31.51 | Dev machine — you are here. Run all commands directly. |
+| pic1 | 192.168.31.52 | Test/staging PIC instance |
+| Gitea | 192.168.31.50 | Self-hosted git server (`gitea@192.168.31.50:roof/pic.git`) |
+| DDNS VPS | 192.168.31.101 (LAN) / 178.168.15.65 (public) | PowerDNS + FastAPI for `*.pic.ngo` DDNS |
+
+The `roof` user on pic0 has passwordless sudo and is in the `docker` group — use both freely.

+
+## AI Collaboration Rules
 
 These rules apply to every Claude Code session in this repo:
 
-- **Read memory first** — load `/home/roof/.claude/projects/-home-roof/memory/MEMORY.md` and referenced files at session start.
-- **Dev machine context** — you are already on pic0 (192.168.31.51), the dev machine. Execute commands here directly; do not ask the user to run them.
-- **Use all available agents** — spawn specialized sub-agents (pic-remote, pic-qa, pic-architect, etc.) for tasks that match their description.
-- **make is the only interface** — never call docker/docker-compose directly. All container lifecycle operations go through `make start`, `make stop`, `make build`, `make logs`, etc.
-- **Test every new feature** — after implementing any change, run `make test` before considering the task done.
-- **Test before commit** — the pre-commit hook enforces this, but run `make test` manually first and fix all failures before staging files.
+- **Read memory first** — load `/home/roof/.claude/projects/-home-roof/memory/MEMORY.md` at session start; follow referenced memory files for relevant context.
+- **You are on pic0** — execute commands directly here; do not ask the user to run them.
+- **`make` is the only container interface** — never call `docker` or `docker-compose` directly. All container lifecycle goes through `make start`, `make stop`, `make build`, `make logs`, etc.
+- **Use specialized agents** — spawn `pic-remote` for VPS/pic1 SSH tasks, `pic-qa` for test writing, `pic-architect` for design decisions, `pic-designer` for UI review, `pic-devops` for docker-compose/Makefile changes, `pic-writer` for documentation.
+- **Test before commit** — run `make test` and fix all failures before staging. The pre-commit hook enforces this, but run it manually first.
+- **No skipping hooks** — never use `--no-verify` unless the only change is documentation or a workflow file with no Python/JS.
+- **Commits need context** — write commit messages that explain *why*, not just *what*. Always add the Co-Authored-By trailer.

 # Quick Start
 
-This guide walks through a first-time PIC installation from a clean Linux host.
+This guide walks through a first-time PIC installation on a clean Linux host.
 
 ---
 
 ## Prerequisites
 
-- Linux host with the WireGuard kernel module (`modprobe wireguard` to verify)
-- Docker Engine and Docker Compose installed
-- Python 3.10+ (needed for `make setup` only)
+- Linux x86-64 host — Debian, Ubuntu, Fedora, RHEL, or Alpine
 - 2 GB+ RAM, 10 GB+ disk
+- Always-required ports: 53, 80, 443, 51820/udp
+- Email service only (when installed): 25, 587, 993
+- WireGuard kernel module available on the host (`modprobe wireguard`); required — userspace WireGuard is not supported
+
+The installer handles all software dependencies (git, docker, make, etc.) automatically.
 
 ---
 
-## 1. Clone the repository
+## Option A — One-line installer (recommended)
 
 ```bash
-git clone <repo-url> pic
+curl -fsSL https://install.pic.ngo | sudo bash
+```
+
+Always review the script before running it:
+
+```bash
+curl -fsSL https://install.pic.ngo | less
+```
+
+The installer runs 7 steps and prints clean one-line progress for each. Run with `PIC_DEBUG=1` or `--debug` for full verbose output. A complete log is always written to `/var/log/pic-install.log`.
+
+The installer:
+1. Detects your OS and installs Docker, git, make via the system package manager
+2. Installs and starts host NTP (chrony) — required for ACME certificate issuance and DDNS token registration
+3. Creates a `pic` system user and adds it to the `docker` group
+4. Clones the repository to `/opt/pic`
+5. Runs `make install` — generates keys and config, writes a systemd unit. The admin password is printed once here; it does not appear again.
+6. Runs `make start-core` to bring up the six core containers
+7. Enables the `pic` systemd unit so the stack starts on reboot, then waits for the API health check
+
+When it finishes, open the URL it prints:
+
+```
+http://<host-ip>:8081/setup
+```
+
+---
+
+## Option B — Manual install
+
+Use this if you want to control where PIC is installed, or if you are installing on a machine that already has Docker.
+
+```bash
+git clone https://git.pic.ngo/roof/pic.git pic
 cd pic
+sudo make install
+make start-core
 ```
 
----
+Then open `http://<host-ip>:8081/setup` in a browser.
 
-## 2. Configure the environment
-
-Copy the example environment file and edit it:
+Note: install host NTP before running `make install` if you plan to use `pic_ngo` domain mode. The installer does this automatically in Option A.
 
 ```bash
-cp .env.example .env
+sudo apt-get install -y chrony && sudo systemctl enable --now chrony
 ```
 
-Open `.env` and set at minimum:
-
-```
-WEBDAV_PASS=changeme
-```
-
-`WEBDAV_PASS` must be set before starting — the WebDAV container will fail to start without it.
-
-All other variables have working defaults. See the Configuration section in [README.md](README.md) for the full list.
-
 ---
 
-## 3. Run setup
+## Complete the setup wizard
 
-`make setup` installs system dependencies, generates WireGuard keys, and writes all required config files under `config/`:
+The setup wizard appears automatically on first start. All API requests redirect to `/setup` until it is finished.
 
-```bash
-make check-deps    # installs docker, python3-cryptography, etc. via apt
-make setup         # generates keys and writes configs
-```
+The wizard asks for:
 
-To customise the cell identity at setup time, pass overrides on the command line:
+- **Cell name** — used for hostnames and DDNS subdomain. Lowercase letters, digits, hyphens, 2–31 characters. Example: `myhome`.
+- **Domain mode** — how HTTPS certificates are issued:
+  - `pic_ngo` — automatic `<cell-name>.pic.ngo` subdomain with a wildcard Let's Encrypt cert via DNS-01 (recommended for internet-facing cells; requires accurate host clock)
+  - `cloudflare` — wildcard Let's Encrypt cert via Cloudflare DNS-01 (bring your own domain)
+  - `duckdns` — Let's Encrypt via DuckDNS DNS-01
+  - `http01` — Let's Encrypt via HTTP-01 (no wildcard; cell must be reachable on port 80)
+  - `lan` — internal CA only, no internet required (for LAN-only installs)
+- **Timezone**
+- **Services to install** — email, calendar, files (optional; installed in the background after setup completes; can be added later via the Services store page)
+- **Admin password** — minimum 12 characters, must contain uppercase, lowercase, and a digit
 
-```bash
-CELL_NAME=myhome CELL_DOMAIN=cell VPN_ADDRESS=10.0.0.1/24 WG_PORT=51820 make setup
-```
-
-`VPN_ADDRESS` must be an RFC-1918 address (e.g. `10.0.0.1/24`).
+Click **Complete Setup**. The wizard creates the admin account, writes cell identity to `config/api/cell_config.json`, and redirects to the login page. Any services you selected begin installing in the background.
 
 ---
 
-## 4. Start the stack
+## Log in
 
-```bash
-make start
-```
+After the wizard you are redirected to `/login`.
 
-This builds the `cell-api` and `cell-webui` images and starts all 13 containers. The first run takes a few minutes while images are pulled and built.
-
-Check that everything came up:
-
-```bash
-make status
-```
-
-You should see all containers in the `Up` state and the API responding at `http://localhost:3000/health`.
+- **Username:** `admin`
+- **Password:** the password you set in the wizard
 
 ---
 
-## 5. Open the web UI
+## Add a WireGuard peer
 
-Open a browser and go to:
-
-```
-http://<host-ip>:8081
-```
-
-If you are running locally:
-
-```
-http://localhost:8081
-```
-
-The sidebar contains: Dashboard, Peers, Network Services, WireGuard, Email, Calendar, Files, Routing, Vault, Containers, Cell Network, Logs, Settings.
-
----
-
-## 6. Set cell identity
-
-Go to **Settings** in the sidebar.
-
-Set your:
-- **Cell name** — a short identifier, e.g. `myhome`
-- **Domain** — the TLD your cell will use internally, e.g. `cell`
-- **VPN IP range** — the CIDR for WireGuard peers, e.g. `10.0.0.0/24`
-
-After saving, the UI will show a banner asking you to apply the changes. Click **Apply Now**. The containers will restart briefly to pick up the new configuration.
-
----
-
-## 7. Add a WireGuard peer
-
-Go to **WireGuard** in the sidebar.
+Go to **Peers** in the sidebar.
 
 1. Click **Add Peer**.
-2. Enter a name for the peer (e.g. `laptop`).
+2. Enter a peer name (e.g. `laptop`).
 3. The API generates a key pair and assigns the next available VPN IP automatically.
-4. Click the QR code icon to display the peer config as a QR code.
+4. Click the QR code icon to display the peer configuration as a QR code.
 5. Scan the QR code with a WireGuard client (Android, iOS, or the WireGuard desktop app).
 
-The peer config sets your cell as the DNS server. Once connected, `*.cell` names resolve through the cell's CoreDNS.
-
-To manage peers from the command line:
-
-```bash
-make list-peers
-make add-peer PEER_NAME=phone PEER_IP=10.0.0.3 PEER_KEY=<base64-pubkey>
-```
+Once connected, `*.cell` names resolve through the cell's CoreDNS and traffic can be routed through the cell.
 
 ---
 
-## 8. Day-to-day operations
+## Installing and managing services
+
+Email, calendar, and file storage are optional services installed from the built-in service store. They are not running by default.
+
+**To install a service:**
+
+1. Go to **Services** in the sidebar.
+2. Find the service card (Email, Calendar, Files, or any other listed service).
+3. Click **Install**. PIC fetches the manifest, starts the container, and wires up DNS and Caddy routes automatically.
+4. The service appears in the sidebar navigation once installation completes.
+
+**To check service status:**
+
+The Services page shows each installed service as "running" or "stopped". You can also check via the API:
 
 ```bash
+curl -s http://<host-ip>:3000/api/services/active
+```
+
+**To uninstall a service:**
+
+Click **Uninstall** on the service card. The container is stopped and removed. Data in `data/services/<id>/` is kept on disk unless you delete it manually.

-## 9. Backup
-
-Before making significant changes, create a backup:
+## Backup and restore
 
 ```bash
-make backup
+make backup      # archives config/ and data/ into backups/cell-backup-<timestamp>.tar.gz
+make restore     # list available backups
 ```
 
-This archives `config/` and `data/` into `backups/cell-backup-<timestamp>.tar.gz`.
+The backup archive is written mode `0600`. It contains secrets and key material — WireGuard keys, the internal CA, vault keys, admin credentials, DDNS token, cell links, and Caddy certificates. Store it securely.
 
-To list available backups:
+Data volumes for installed store services (email mailboxes, calendar data, file storage) are captured separately via the API-driven backup (`POST /api/config/backup`), which also supports an optional passphrase for encryption at rest. The encrypted file is named `<backup_id>.tar.gz.age`.
 
-```bash
-make restore

-
-To restore manually:
+To restore from a `make backup` archive:
 
 ```bash
 tar -xzf backups/cell-backup-YYYYMMDD-HHMMSS.tar.gz
-make start
+make restart
 ```
 
-Backup and restore is also available in the UI under **Settings**.
+After restore, the API re-generates the Caddyfile and Corefile from the restored config and re-applies routing rules automatically.

+## Updating PIC
 
 ```bash
-make update

-All containers run on a custom Docker bridge network (`cell-network`, default `172.20.0.0/16`). Static IPs per container are set in `docker-compose.yml` and overridden via `.env`.
+Six core containers run on a Docker bridge network (`cell-network`, default subnet `172.20.0.0/16`). Static IPs per container are set in `docker-compose.yml` and can be overridden via `.env`. Installed service containers join the same network with their own compose projects managed by `ServiceComposer`.
 
-The Flask API (`api/app.py`, ~2800 lines) contains all REST endpoints, runs a background health-monitoring thread, and manages the entire lifecycle of generated config artefacts: `Caddyfile`, `Corefile`, `wg0.conf`, and `cell_config.json` (the single source of truth at `config/api/cell_config.json`).
+The Flask API (`api/app.py`) contains REST endpoints and a background health-monitoring thread. Service managers are instantiated as singletons in `api/managers.py`. The single source of truth for runtime configuration is `config/api/cell_config.json`, managed by `ConfigManager`.
 
-The React frontend (`webui/`) is built with Vite + Tailwind CSS. All API calls go through `src/services/api.js` (Axios). Pages: Dashboard, Peers, Network Services, WireGuard, Email, Calendar, Files, Routing, Vault, Containers, Cell Network, Logs, Settings.

+**Web UI pages:** Dashboard, Peers, Network Services, WireGuard, Email, Calendar, Files, Routing, Vault, Containers, Cell Network, Connectivity, Service Store, Logs, Settings.
+

+
+## Features
+
+- **First-run wizard** — browser-based setup at `/setup`. On first start, all API requests redirect to `/setup` (HTTP 428) until the wizard is completed. Sets cell name, domain mode, timezone, admin password, and initial services. No manual `.env` editing required for identity.
+- **Session-based auth** — admin and peer roles. All `/api/*` endpoints require an authenticated session after setup. CSRF protection on all state-changing requests.
+- **WireGuard VPN** — peer lifecycle management, automatic key generation, QR code config export, per-peer routing policy.
+- **Caddy HTTPS** — automatic TLS via Let's Encrypt (DNS-01 or HTTP-01) or an internal CA, depending on domain mode.
+- **DDNS (pic.ngo)** — registers a `<cell-name>.pic.ngo` subdomain. Supported providers: `pic_ngo`, `cloudflare`, `duckdns`, `noip`, `freedns`. A background thread re-publishes the public IP every 5 minutes.
+- **Service store** — install/remove optional third-party services from the `pic-services` index at `git.pic.ngo`. Manifests declare container images, Caddy routes, and iptables rules.
+- **Extended connectivity** — per-peer egress routing through alternate exits: WireGuard external, OpenVPN, Tor, sshuttle (SSH tunnel), or proxy (HTTP/SOCKS5 via redsocks). Exit nodes are optional store services. Per-service egress policy is also supported. Routing uses fwmark and `ip rule` in the WireGuard container.
+- **Cell-to-cell networking** — WireGuard-based site-to-site links between PIC cells with service-level access control (calendar, files, mail, WebDAV) and a peer-sync protocol.
+- **Certificate authority** — `vault_manager` issues and revokes TLS certificates for internal services.
+- **Network services** — CoreDNS (`.cell` TLD and split-horizon DNS for the cell domain), chrony NTP.
+- **Split-horizon DNS** — from outside the VPN, the cell domain resolves to the public IP. Inside the VPN, CoreDNS resolves it to the WireGuard IP so traffic stays in the tunnel. Caddy serves on both interfaces.
+- **Email** _(optional, install via Service Store)_ — Postfix + Dovecot via `docker-mailserver`.
+- **Calendar/contacts** _(optional, install via Service Store)_ — Radicale CalDAV/CardDAV.
+- **File storage** _(optional, install via Service Store)_ — WebDAV with per-user accounts; Filegator for browser-based file management.
+- **Container manager** — start/stop/inspect containers, pull images, manage volumes via the Docker SDK.
+- **Firewall manager** — iptables rule management (`firewall_manager.py`).
+- **Structured logging** — JSON logs with rotation (5 MB / 5 backups per service), log search, and per-service verbosity control.

 ## Requirements
 
-- Linux host with the WireGuard kernel module loaded
+- Linux host with the WireGuard kernel module loaded (`modprobe wireguard` to verify; required — userspace WireGuard is not supported)
 - Docker Engine and Docker Compose (v2 plugin or v1 standalone)

+- Python 3.10+ (for `make setup` and local development; not needed at runtime)
 - 2 GB+ RAM, 10 GB+ disk
-- Ports available: 53, 67/udp, 80, 443, 51820/udp, 25, 587, 993

 ## Quick Start
 
-See [QUICKSTART.md](QUICKSTART.md) for step-by-step setup.
+See [QUICKSTART.md](QUICKSTART.md) for step-by-step instructions.
+
+The short version — one-line installer (recommended):
+
+```bash
+curl -fsSL https://install.pic.ngo | sudo bash
+# open http://<host-ip>:8081/setup — the setup wizard appears automatically
+```
+
+Or clone manually for development:
+
+```bash
+git clone https://git.pic.ngo/roof/pic.git pic
+cd pic
+make start
+# open http://<host-ip>:8081 — the setup wizard appears automatically
+```
 
 ---
 
 ## Configuration
 
-Runtime configuration is controlled by `.env` in the project root. Copy `.env.example` to `.env` before first run.
+Port assignments and container IPs are configured in `.env` in the project root. A `.env` file is not required for first start — all variables have defaults. Create one only if you need to change ports or container IPs.
 
 | Variable | Default | Description |
 |---|---|---|
-| `CELL_NETWORK` | `172.20.0.0/16` | Docker bridge subnet for all containers |
-| `CADDY_IP` through `FILEGATOR_IP` | `172.20.0.2`–`.13` | Static IP for each container |
-| `DNS_PORT` | `53` | DNS (UDP+TCP) |
-| `DHCP_PORT` | `67` | DHCP (UDP) |
+| `CELL_NETWORK` | `172.20.0.0/16` | Docker bridge subnet |
+| `CADDY_IP` through `WG_IP` | `172.20.0.2`–`.11` | Static IP per core container |
+| `DNS_PORT` | `53` | DNS (UDP + TCP) |
 | `NTP_PORT` | `123` | NTP (UDP) |
 | `WG_PORT` | `51820` | WireGuard listen port (UDP) |
-| `API_PORT` | `3000` | Flask API (bound to `127.0.0.1`) |
-| `WEBUI_PORT` | `8081` | React UI |
-| `MAIL_SMTP_PORT` | `25` | SMTP |
-| `MAIL_SUBMISSION_PORT` | `587` | SMTP submission |
-| `MAIL_IMAP_PORT` | `993` | IMAP |
-| `RADICALE_PORT` | `5232` | CalDAV (bound to `127.0.0.1`) |
-| `WEBDAV_PORT` | `8080` | WebDAV (bound to `127.0.0.1`) |
-| `RAINLOOP_PORT` | `8888` | Webmail |
-| `FILEGATOR_PORT` | `8082` | File manager UI |
-| `WEBDAV_USER` | `admin` | WebDAV basic-auth username |
-| `WEBDAV_PASS` | _(required)_ | WebDAV basic-auth password — must be set before `make start` |
-| `FLASK_DEBUG` | _(unset)_ | Set to `1` to enable Flask debug mode; do not use in production |
+| `API_PORT` | `3000` | Flask API (127.0.0.1 only) |
+| `WEBUI_PORT` | `8081` | Host port mapped to container port 8080 |
+| `FLASK_DEBUG` | _(unset)_ | Set to `1` for Flask debug mode; do not use in production |
 | `PUID` / `PGID` | current user | UID/GID passed to the WireGuard container |
 
-Cell identity (cell name, domain, VPN IP range) is configured via `make setup` or the Settings → Identity page in the UI after startup. The VPN IP range must be an RFC-1918 CIDR (`10.0.0.0/8`, `172.16.0.0/12`, or `192.168.0.0/16`); the API and UI both enforce this.
+Cell identity (cell name, domain mode, timezone) is set through the first-run wizard on first start, or later through the Settings page in the UI.

-- `53` — DNS (UDP + TCP)
-- `67/udp` — DHCP
+- `53` — DNS
 - `8081` — Web UI
-- `8888` — Webmail (RainLoop)
-- `8082` — File manager (Filegator)
+- `25` / `587` / `993` — mail _(only when the email service is installed)_
 
-**Ports bound to `127.0.0.1` only** (not directly reachable from the network):
+**Ports bound to `127.0.0.1` only:**
 
 - `3000` — Flask API
-- `5232` — Radicale (CalDAV)
-- `8080` — WebDAV
 
-The API has no authentication layer. It relies on `is_local_request()` to restrict sensitive endpoints (containers, vault) to requests originating from loopback or the cell's Docker network. The Docker socket is mounted into `cell-api`; treat access to port 3000 as equivalent to root access on the host.
+The API uses session-based authentication (admin and peer roles). The Docker socket is mounted into `cell-api`; treat access to port 3000 as equivalent to root access on the host.
 
-For internet-facing deployments, place the host behind a firewall or VPN and restrict access to the API and UI ports.
+Before setup is complete, all `/api/*` requests except `/api/setup/*` and `/health` return HTTP 428 and a redirect to `/setup`.
+
+CSRF protection (double-submit token in `X-CSRF-Token` header) applies to all `POST`, `PUT`, `DELETE`, and `PATCH` requests on `/api/*` once a user session exists, except `/api/auth/*` and `/api/setup/*`.
+
+Cell-to-cell peer-sync endpoints (`/api/cells/peer-sync/*`) authenticate via source IP and WireGuard public key, not session cookies.
+
+For internet-facing deployments, place the host behind a firewall and restrict access to the API and UI ports.

+AccountManager — per-service credential provisioning for PIC peers.

+Responsibilities:
+  - Dispatch account creation/deletion to each service's underlying manager
+  - Store per-peer per-service credentials securely (0o600 file)
+  - Provide credential retrieval for peer_config_template filling
+  - Bulk-deprovision a peer from all services on peer deletion

+    }
+  }
+
+Design note — plaintext passwords:
+  Credentials are stored in plaintext so the peer endpoint can return them to
+  the peer's device for one-time client configuration. The file is created with
+  0o600 so it is only readable by the process owner (same pattern used for
+  WireGuard keys and service_secrets.json).

+EgressManager — per-service egress enforcement.
+
+Routes outbound traffic from installed service containers through
+alternate exits (wireguard_ext, openvpn, tor) using host-side
+iptables fwmark policy-routing. Integrates with ServiceStoreManager
+for install/remove lifecycle hooks.
+
+Rules live on the HOST in PIC_EGRESS chains in the mangle and nat
+tables. Container IPs are discovered via docker inspect using the
+container_name from the service manifest.
+
+Connectivity v2: a service routes through a *connection instance* (by id),
+sharing the same fwmark / routing table / redirect port as any peer that
+egresses through the same connection. The (mark, table, redirect_port) for a
+service are resolved from ConnectivityManager.get_connection(id) — EgressManager
+no longer owns its own per-type MARKS/TABLES tables.

-
-## Overview
-
-The Personal Internet Cell provides a complete VPN solution with internet access. This requires proper configuration of:
-
-- **IP Forwarding**: Allow traffic to pass through the server
-- **NAT (Network Address Translation)**: Translate private IPs to public IPs
-- **Routing**: Direct traffic from VPN clients to the internet
-- **Firewall Rules**: Control traffic flow and security
-
-## Network Architecture
-
-```
-Internet
-    │
-    ▼
-[Host Server] (195.178.106.244)
-    │
-    ├── [Docker Network] (172.20.0.0/16)
-    │   └── [WireGuard Container] (cell-wireguard)
-    │       └── [WireGuard Interface] (wg0: 10.0.0.1/24)
-    │
-    └── [VPN Clients] (10.0.0.2-10.0.0.254/24)
-        └── [Internet Access via NAT]
-```
-
-### Key Components
-
-- **Host Interface**: `eth0` (or main network interface)
-- **WireGuard Interface**: `wg0` (10.0.0.1/24)
-- **Client Network**: `10.0.0.0/24`
-- **NAT Translation**: Client IPs → Host IP
-
-## Quick Setup
-
-### 1. Run the Network Configuration Script
-
-```bash
-# Make the script executable (if not already done)
-chmod +x /opt/pic/scripts/setup-network.sh
-
-# Run the configuration
-sudo /opt/pic/scripts/setup-network.sh setup
-```
-
-### 2. Verify Configuration
-
-```bash
-# Check status
-sudo /opt/pic/scripts/setup-network.sh status
-
-# Test configuration
-sudo /opt/pic/scripts/setup-network.sh test
-```
-
-### 3. Connect a VPN Client
-
-Use the generated WireGuard configuration to connect a client. The client should now have internet access.
-
-## Detailed Configuration
-
-### IP Forwarding
-
-IP forwarding allows the server to route packets between different network interfaces.
-
-**Enable on Host:**
-```bash
-echo 'net.ipv4.ip_forward = 1' >> /etc/sysctl.conf
-sysctl -p
-```
-
-**Enable in Container:**
-```bash
-docker exec cell-wireguard sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
-```
-
-### NAT Configuration
-
-NAT (Network Address Translation) allows VPN clients to access the internet using the server's public IP.
-
-**Container NAT Rules:**
-```bash
-# Allow forwarding for WireGuard traffic
-iptables -A FORWARD -i wg0 -j ACCEPT
-iptables -A FORWARD -o wg0 -j ACCEPT
-
-# NAT rule for internet access
-iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j MASQUERADE
-```
-
-**Host NAT Rules:**
-```bash
-# Allow traffic from WireGuard network
-iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j MASQUERADE
-iptables -A FORWARD -i wg0 -j ACCEPT
-iptables -A FORWARD -o wg0 -j ACCEPT
-```
-
-### Routing Configuration
-
-**WireGuard Interface Setup:**
-```bash
-# Create WireGuard interface
-ip link add dev wg0 type wireguard
-
-# Set private key
-wg set wg0 private-key /path/to/private-key
-
-# Set listen port
-wg set wg0 listen-port 51820
-
-# Add IP address
-ip addr add 10.0.0.1/24 dev wg0
-
-# Bring interface up
-ip link set wg0 up
-
-# Add peers
-wg set wg0 peer <public-key> allowed-ips 10.0.0.2/32
-```
-
-## Troubleshooting
-
-### Common Issues
-
-#### 1. VPN Connected but No Internet
-
-**Symptoms:**
-- WireGuard shows connected
-- Can ping server (10.0.0.1)
-- Cannot access internet
-
-**Solutions:**
-```bash
-# Check IP forwarding
-cat /proc/sys/net/ipv4/ip_forward
-# Should return 1
-
-# Check NAT rules
-iptables -t nat -L POSTROUTING -n
-# Should show MASQUERADE rule for 10.0.0.0/24
-
-# Check forwarding rules
-iptables -L FORWARD -n
-# Should show ACCEPT rules for wg0
-
-# Restart network configuration
-sudo /opt/pic/scripts/setup-network.sh reset
-sudo /opt/pic/scripts/setup-network.sh setup
-```
-
-#### 2. Cannot Connect to VPN
-
-**Symptoms:**
-- WireGuard client cannot connect
-- No handshake in server logs
-
-**Solutions:**
-```bash
-# Check WireGuard interface
-docker exec cell-wireguard wg show
-
-# Check if port 51820 is open
-netstat -ulnp | grep 51820
-
-# Check firewall rules
-ufw status
-iptables -L INPUT -n
-
-# Check Docker port mapping
-docker port cell-wireguard
-```
-
-#### 3. DNS Issues
-
-**Symptoms:**
-- Can ping IP addresses
-- Cannot resolve domain names
-
-**Solutions:**
-```bash
-# Check DNS configuration in client config
-# Should include: DNS = 8.8.8.8, 1.1.1.1
-
-# Test DNS from container
-docker exec cell-wireguard nslookup google.com
-
-# Check if DNS is being blocked
-docker exec cell-wireguard iptables -L -n | grep 53
-```
-
-### Diagnostic Commands
-
-```bash
-# Check network status
-sudo /opt/pic/scripts/setup-network.sh status
-
-# Test connectivity from container
-docker exec cell-wireguard ping -c 3 8.8.8.8
-
-# Check routing table
-docker exec cell-wireguard ip route show
-
-# Check interface status
-docker exec cell-wireguard ip addr show wg0
-
-# Check NAT rules
-docker exec cell-wireguard iptables -t nat -L -n
-
-# Check forwarding rules
-docker exec cell-wireguard iptables -L FORWARD -n
-```
-
-## Advanced Configuration
-
-### Custom DNS Servers
-
-To use custom DNS servers, modify the WireGuard client configuration:
-
-```ini
-[Interface]
-PrivateKey = <private-key>
-Address = 10.0.0.2/32
-DNS = 1.1.1.1, 1.0.0.1, 8.8.8.8, 8.8.4.4
-
-[Peer]
-PublicKey = <server-public-key>
-Endpoint = 195.178.106.244:51820
-AllowedIPs = 0.0.0.0/0
-PersistentKeepalive = 25
-```
-
-### Split Tunneling
-
-To allow only specific traffic through the VPN:
-
-```ini
-[Peer]
-AllowedIPs = 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
-# Only route private networks through VPN
-```
-
-### Port Forwarding
-
-To forward specific ports to VPN clients:
-
-```bash
-# Forward port 8080 to client 10.0.0.2
-iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 10.0.0.2:8080
-iptables -A FORWARD -p tcp -d 10.0.0.2 --dport 8080 -j ACCEPT
-```
-
-### Bandwidth Limiting
-
-To limit bandwidth for VPN clients:
-
-```bash
-# Install tc (traffic control)
-apt-get install iproute2
-
-# Limit client 10.0.0.2 to 1Mbps
-tc qdisc add dev wg0 root handle 1: htb default 30
-tc class add dev wg0 parent 1: classid 1:1 htb rate 1mbit
-tc class add dev wg0 parent 1:1 classid 1:10 htb rate 1mbit ceil 1mbit
-tc filter add dev wg0 protocol ip parent 1:0 prio 1 u32 match ip dst 10.0.0.2 flowid 1:10
-```
-
-## Security Considerations
-
-### Firewall Rules
-
-**Basic Security Rules:**
-```bash
-# Drop invalid packets
-iptables -A INPUT -m conntrack --ctstate INVALID -j DROP
-
-# Allow established connections
-iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
-
-# Allow WireGuard traffic
-iptables -A INPUT -p udp --dport 51820 -j ACCEPT
-
-# Allow SSH (if needed)
-iptables -A INPUT -p tcp --dport 22 -j ACCEPT
-
-# Drop everything else
-iptables -A INPUT -j DROP
-```
-
-### Client Isolation
-
-To prevent clients from communicating with each other:
-
-```bash
-# Block inter-client communication
-iptables -A FORWARD -i wg0 -o wg0 -j DROP
-```
-
-### Logging
-
-To log VPN traffic:
-
-```bash
-# Log all WireGuard traffic
-iptables -A FORWARD -i wg0 -j LOG --log-prefix "WG-FORWARD: "
-iptables -A FORWARD -o wg0 -j LOG --log-prefix "WG-FORWARD: "
-
-# Log NAT traffic
-iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -j LOG --log-prefix "WG-NAT: "
-```
-
-## Monitoring
-
-### Real-time Monitoring
-
-```bash
-# Monitor WireGuard connections
-watch -n 1 "docker exec cell-wireguard wg show"
-
-# Monitor traffic
-watch -n 1 "docker exec cell-wireguard wg show wg0 transfer"
-
-# Monitor NAT rules
-watch -n 1 "iptables -t nat -L POSTROUTING -n -v"
-```
-
-### Log Analysis
-
-```bash
-# Check system logs
-journalctl -u pic-network.service -f
-
-# Check iptables logs
-tail -f /var/log/kern.log | grep WG-
-
-# Check Docker logs
-docker logs cell-wireguard -f
-```
-
-## Backup and Recovery
-
-### Backup Configuration
-
-```bash
-# Backup iptables rules
-iptables-save > /opt/pic/backups/iptables-backup-$(date +%Y%m%d).rules
-
-# Backup WireGuard configuration
-cp /opt/pic/config/wireguard/wg_confs/wg0.conf /opt/pic/backups/wg0-backup-$(date +%Y%m%d).conf
-
-# Backup network script
-cp /opt/pic/scripts/setup-network.sh /opt/pic/backups/setup-network-backup-$(date +%Y%m%d).sh
-```
-
-### Restore Configuration
-
-```bash
-# Restore iptables rules
-iptables-restore < /opt/pic/backups/iptables-backup-YYYYMMDD.rules
-
-# Restore WireGuard configuration
-cp /opt/pic/backups/wg0-backup-YYYYMMDD.conf /opt/pic/config/wireguard/wg_confs/wg0.conf
-docker restart cell-wireguard

+# PIC Service Developer Guide
+
+This guide is for developers who want to build services that integrate with Personal Internet Cell (PIC). It covers the manifest format, how PIC wires up routing, DNS, backup, and account provisioning for your service, and how to package and submit your work.
+
+**Prerequisites:** you should be comfortable with Docker, Docker Compose, and basic Linux networking. You do not need to know Python to build a store service.
+
+---
+

+
+1. [What a PIC service is](#1-what-a-pic-service-is)
+2. [Manifest reference](#2-manifest-reference)
+3. [Compose template variables](#3-compose-template-variables)
+4. [Account provisioning interface](#4-account-provisioning-interface)

+9. [Submitting to the store](#9-submitting-to-the-store)
+
+---
+
+## 1. What a PIC service is
+
+A PIC service is a Docker container (or a set of containers) that plugs into the PIC ecosystem through a single JSON file called the **manifest**. The manifest tells PIC everything it needs to know:
+
+- How to route HTTPS traffic to the service through Caddy
+- What subdomains to expose
+- Which users get accounts on the service and what credentials they receive
+- Which paths to include in automated backups
+- Which outbound network interfaces the service is allowed to use
+
+All PIC services are **store services** — optional packages installed by the cell admin from the `pic-services` catalog. PIC downloads the manifest, renders a per-service Docker Compose file, and starts the containers. The core PIC stack (DNS, NTP, WireGuard, Caddy, API, WebUI) runs independently of any installed services.
+
+The email, calendar, and files services (in `pic-services/services/`) are the reference implementations and show the full feature set. The `ServiceRegistry` in `api/service_registry.py` is the single source of truth for all installed services. `CaddyManager`, the backup system, and the peer services endpoint all read from it rather than from hardcoded lists.
+
+---
+
+## 2. Manifest reference
+
+The manifest is a JSON file with `"schema_version": 3`. Every field is described below. The `email`, `calendar`, and `files` manifests in `pic-services/services/` are the canonical reference examples.
+
+### Top-level identity fields
+
+| Field | Type | Required | Description |
+|---|---|---|---|
+| `schema_version` | integer | yes | Must be `3`. |
+| `id` | string | yes | Unique service identifier, lowercase, no spaces (e.g. `"notes"`). Must match the directory name for builtins, or the store index entry for store services. |
+| `name` | string | yes | Human-readable display name (e.g. `"Notes"`). |
+| `description` | string | yes | One-sentence description shown in the UI. |
+| `version` | string | yes | Semver string for the service package itself (e.g. `"1.0.0"`). |
+| `author` | string | yes | Your name or organisation. |
+| `kind` | string | yes | Must be `"store"`. |
+| `min_pic_version` | string | no | Minimum PIC version required (e.g. `"1.0"`). |
+
+```json
+{
+  "schema_version": 3,
+  "id": "notes",
+  "name": "Notes",
+  "description": "Self-hosted Markdown notes with full-text search",
+  "version": "1.0.0",
+  "author": "acme",
+  "kind": "store",
+  "min_pic_version": "1.0"
+}
+```
+
+### `capabilities`
+
+A set of boolean flags that tell PIC which integrations to activate for your service.
+
+| Field | Type | Default | Description |
+|---|---|---|---|
+| `has_subdomain` | bool | `false` | The service gets a subdomain and a Caddy reverse-proxy route. Requires `subdomain` and `backend`. |
+| `has_accounts` | bool | `false` | The service provisions per-peer accounts. Requires `accounts`. |
+| `has_admin_config` | bool | `false` | The service has admin-configurable fields. Requires `config_schema`. |
+| `has_storage` | bool | `false` | The service has data worth backing up. Requires `backup`. |
+| `has_egress` | bool | `false` | The admin can choose which outbound interface this service uses. Requires `egress`. |
+| `has_api_hooks` | bool | `false` | Reserved for future use; set `false`. |
+
+```json
+"capabilities": {
+  "has_subdomain": true,
+  "has_accounts": true,
+  "has_admin_config": false,
+  "has_storage": true,
+  "has_egress": false,
+  "has_api_hooks": false
+}
+```
+
+### `subdomain`, `extra_subdomains`, `backend`, `extra_backends`
+
+These fields are only read when `has_subdomain` is `true`.
+
+| Field | Type | Required | Description |
+|---|---|---|---|
+| `subdomain` | string | yes (if `has_subdomain`) | The primary subdomain (e.g. `"notes"`). Results in `notes.<cell-domain>`. Must not collide with reserved names: `api`, `webui`, `admin`, `www`, `ns1`, `ns2`, `git`, `registry`, `install`. |
+| `extra_subdomains` | array of strings | no | Additional subdomains that point to the same backend (e.g. `["webmail"]`). |
+| `backend` | string | yes (if `has_subdomain`) | The container-name:port combination that Caddy proxies to (e.g. `"cell-notes:8080"`). Uses Docker DNS on the `cell-network`. |
+| `extra_backends` | object | no | Maps extra subdomain names to separate backends. Key is the subdomain string; value is the backend string. The email service uses this to send `webdav.*` to a different container than `files.*`. |
+
+```json
+"subdomain": "notes",
+"extra_subdomains": [],
+"backend": "cell-notes:8080"
+```
+
+**Validation at runtime:** `ServiceRegistry.get_caddy_routes()` validates all subdomain and backend values before passing them to CaddyManager or NetworkManager. Any entry whose `subdomain` does not match `^[a-z][a-z0-9-]{0,30}$`, whose `backend` does not match `^[A-Za-z0-9._-]+:\d{1,5}$`, or whose `subdomain` appears in the reserved list is silently skipped with a warning log. The same validation applies to `extra_subdomains` and `extra_backends` keys/values. For store services, this validation is also performed during installation by `ServiceStoreManager._validate_manifest()`.
+
+### `containers`
+
+Array of container names that belong to this service. Used by the UI and log viewer. For builtins this is informational; for store services PIC only manages the single container declared in the manifest.
+
+```json
+"containers": ["cell-notes"]
+```
+
+### `config_schema`
+
+Defines admin-configurable fields for this service. When `has_admin_config` is `true`, the UI renders a settings form from this schema. PIC stores admin-saved values in `cell_config.json` and merges them with your `default` values at runtime. The merged result is available as the `config` key when `ServiceRegistry.get()` returns your service.
+
+Each field is an object:
+
+| Key | Type | Required | Description |
+|---|---|---|---|
+| `type` | string | yes | One of `"string"`, `"integer"`, `"boolean"`. |
+| `label` | string | yes | Human-readable label for the settings form. |
+| `required` | bool | no | Whether the field must have a value before the service starts. |
+| `default` | any | no | Default value used when the admin has not set one. |
+| `min` / `max` | integer | no (integer only) | Inclusive bounds for integer fields. |
+
+```json
+"config_schema": {
+  "port": {
+    "type": "integer",
+    "label": "Internal HTTP port",
+    "default": 8080,
+    "min": 1,
+    "max": 65535
+  },
+  "storage_path": {
+    "type": "string",
+    "label": "Data directory inside container",
+    "default": "/data/notes"
+  }
+}
+```
+
+### `peer_config_template`
+
+When a peer is provisioned on this service, PIC fills this template and returns the result to the peer as their connection info. Template substitution tokens:
+
+| Token | Replaced with |
+|---|---|
+| `{domain}` | The cell's public domain (e.g. `alice.pic.ngo`) |
+| `{peer.username}` | The peer's username |
+| `{peer.service_credentials.<id>.<field>}` | A credential value; `<id>` is the service `id`, `<field>` matches a name in `accounts.credentials` |
+| `{config.<key>}` | A value from the merged `config_schema` result |
+
+```json
+"peer_config_template": {
+  "url": "https://notes.{domain}/",
+  "username": "{peer.username}",
+  "password": "{peer.service_credentials.notes.password}"
+}
+```
+
+### `accounts`
+
+Required when `has_accounts` is `true`.
+
+| Field | Type | Description |
+|---|---|---|
+| `manager` | string | Set to `"http"` for store services — PIC will call your container's HTTP API for account operations (see section 4). The reference services (`email`, `calendar`, `files`) use internal manager names (`"email_manager"`, `"calendar_manager"`, `"file_manager"`). |
+| `credentials` | array of strings | Names of credential fields this service issues per peer. Most services use `["password"]`. The names appear in `peer_config_template` tokens. |
+
+```json
+"accounts": {
+  "manager": "http",
+  "credentials": ["password"]
+}
+```
+
+### `compose`
+
+Unused at the manifest level. Compose configuration is provided via `compose-template.yml` in the service package (see section 3). Set to `null` in the manifest.
+
+### `backup`
+
+Required when `has_storage` is `true`. Tells PIC's backup system what to snapshot.
+
+| Field | Type | Description |
+|---|---|---|
+| `volumes` | array of objects | Container paths to stream out via `docker exec tar`. Each entry has three string fields: `container` (container name), `path` (absolute path inside the container), and `name` (archive filename stem). |
+| `config_paths` | array of strings | Paths relative to the PIC project root on the host that contain service configuration (not user data). Copied directly into the snapshot. |
+
+Each entry in `volumes` produces an archive at `<name>.tar.gz` inside the snapshot. For example, `"name": "maildata"` produces `maildata.tar.gz`.
+
+```json
+"backup": {
+  "volumes": [
+    {"container": "cell-notes", "path": "/data/notes", "name": "notes_data"}
+  ],
+  "config_paths": ["config/notes"]
+}
+```
+
+`ServiceRegistry.get_backup_plan()` aggregates these declarations across all installed services. The backup runner reads from that method rather than from any hardcoded list.
+
+### `egress`
+
+Required when `has_egress` is `true`. Declares which outbound network interfaces this service is permitted to use.
+
+| Field | Type | Description |
+|---|---|---|
+| `default` | string | The interface selected when the admin has not changed anything. |
+| `allowed` | array of strings | The complete set of interfaces the admin can choose from. |
+
+Valid interface identifiers: `default`, `wireguard_ext`, `openvpn`, `tor`, `sshuttle`, `proxy`.
+
+```json
+"egress": {
+  "default": "default",
+  "allowed": ["default", "wireguard_ext", "openvpn", "tor", "sshuttle", "proxy"]
+}
+```
+
+How enforcement works is described in section 6.
+
+### `storage`
+
+Informational metadata used by the UI to show storage usage.
+
+| Field | Type | Description |
+|---|---|---|
+| `primary_path` | string | The path (relative to project root) that holds the bulk of user data. |
+| `quota_mb` | integer or null | Storage quota in megabytes; `null` means no limit. |
+
+```json
+"storage": {
+  "primary_path": "data/notes",
+  "quota_mb": null
+}
+```
+
+### Store-only manifest fields
+
+Store services (where `kind` is `"store"`) have additional required fields that builtins do not use. These are validated by `ServiceStoreManager._validate_manifest()` before installation is permitted.
+
+| Field | Type | Required | Description |
+|---|---|---|---|
+| `image` | string | yes | Docker image to pull. Must match the pattern `git.pic.ngo/roof/*`. Images from other registries are rejected. |
+| `container_name` | string | yes | The name Docker gives the running container. |
+| `volumes` | array | no | Named volumes to mount. Each entry must have `name` (the volume name) and `mount` (the absolute path inside the container). Mounts to `/`, `/etc`, `/var`, `/proc`, `/sys`, `/dev`, `/app`, `/run`, `/boot`, and paths that are a prefix of the PIC project root are forbidden. |
+| `env` | array | no | Environment variables to pass. Each entry has `key` and `value`. Values must match `^[A-Za-z0-9._@:/+\-= ]*$`. |
+| `iptables_rules` | array | no | FORWARD ACCEPT rules PIC should install in `cell-wireguard`. Each rule must have `type: "ACCEPT"`, `dest_ip: "${SERVICE_IP}"`, an integer `dest_port` (1–65535), and an optional `proto` (`"tcp"` or `"udp"`, default `"tcp"`). The literal string `${SERVICE_IP}` is replaced with the allocated container IP at install time. |
+| `caddy_route` | object | no | If the service exposes a web UI, provide `subdomain` (must not be reserved; must match `^[a-z][a-z0-9-]{0,30}$`). PIC inserts the corresponding `reverse_proxy` directive into the Caddyfile. |
+
+---
+
+## 3. Compose template variables
+
+This section applies only to store services. Builtins define their containers directly in `docker-compose.yml`.
+
+When you ship a store service, you include a `compose-template.yml` alongside your `manifest.json`. `ServiceComposer.render_template()` substitutes the variables below before writing the per-service `docker-compose.yml`.
+
+| Variable | Syntax | Value |
+|---|---|---|
+| `${PIC_CFG_<KEY>}` | uppercase `config_schema` key | The admin-saved value for that field, or the `default` from the schema if the admin has not set it. For example, `config_schema.port` → `${PIC_CFG_PORT}`. |
+| `${PIC_SECRET_<NAME>}` | any name you choose | An auto-generated random secret produced by `secrets.token_urlsafe(24)` (~32 URL-safe base64 characters). Generated once on first install, then reused unchanged on every reconfigure. Stored per service in `data/service_secrets.json`. |
+| `${PIC_DOMAIN}` | literal | Effective domain from `ConfigManager` (e.g. `alice.pic.ngo`). |
+| `${PIC_CELL_NAME}` | literal | Cell name from the identity config (e.g. `alice`). |
+| `${PIC_SERVICE_ID}` | literal | The `id` field from the service manifest (e.g. `notes`). |
+
+**Volume mounts**: Because docker compose runs inside the API container but the Docker daemon runs on the host, relative volume paths in compose templates resolve relative to the compose file's directory as seen by the HOST filesystem. To avoid path resolution surprises, prefer **named volumes** for service data (Docker manages them independently). If bind mounts are required, use absolute host paths with `${PIC_PROJECT_DIR}` once that variable is implemented, or document the expected host layout clearly.
+
+Example `compose-template.yml` for a notes service:
+
+```yaml
+services:
+  cell-notes:
+    image: git.pic.ngo/roof/pic-notes:latest
+    container_name: cell-notes
+    restart: unless-stopped
+    environment:
+      NOTES_PORT: "${PIC_CFG_PORT}"
+      NOTES_DOMAIN: "${PIC_DOMAIN}"
+      NOTES_DB_PASS: "${PIC_SECRET_DB_PASSWORD}"
+    volumes:
+      - notes-data:/data/notes
+    networks:
+      cell-network:
+        ipv4_address: "${SERVICE_IP}"
+
+volumes:
+  notes-data:
+
+networks:
+  cell-network:
+    external: true
+```
+
+The `SERVICE_IP` variable is the IP PIC allocated from the service pool. It is always set automatically.
+
+---
+
+## 4. Account provisioning interface
+
+This section covers two related things: the `AccountManager` class that is PIC's central credential dispatcher, and the HTTP API that store services must implement to receive account operations.
+
+### How AccountManager works
+
+`AccountManager` (`api/account_manager.py`) is the single entry point for all account operations across every service type. It is instantiated once in `api/managers.py` and holds references to the service managers used by the reference services (`email_manager`, `calendar_manager`, `file_manager`).
+
+When a peer account is provisioned, `AccountManager`:
+
+1. Looks up the service in `ServiceRegistry` and reads `accounts.manager` from the manifest.
+2. Dispatches to the appropriate internal manager method (for builtins) or to the service's HTTP API endpoint (for store services — not yet implemented; `"http"` manager support is planned).
+3. Stores the returned credentials in `data/peer_service_credentials.json` with permissions `0o600`.
+
+Credentials are stored in plaintext. This is intentional: the peer credentials endpoint needs to return them verbatim for one-time client configuration. The `0o600` permission matches the pattern used for WireGuard keys and `data/service_secrets.json`.
+
+The credentials file structure is:
+
+```json
+{
+  "<service_id>": {
+    "<peer_username>": { "password": "..." }
+  }
+}
+```
+
+Writes use a write-then-rename pattern (`tmp` → final path) with `os.fsync` to avoid partial-write corruption.
+
+### Manifest `accounts` field
+
+The `accounts` block in the manifest wires a service into `AccountManager`.
+
+| Field | Type | Description |
+|---|---|---|
+| `manager` | string | Which underlying manager handles account operations. For builtins: `"email_manager"`, `"calendar_manager"`, or `"file_manager"`. |
+| `credentials` | array of strings | Names of the credential fields this service issues per peer. Most services use `["password"]`. These names are used as token keys in `peer_config_template`. |
+
+```json
+"accounts": {
+  "manager": "email_manager",
+  "credentials": ["password"]
+}
+```
+
+The `manager` value must match a key that `AccountManager` was instantiated with. If the manager name has no registered dispatch entry, `provision()` raises `ValueError` immediately.
+
+### Provision flow
+
+```
+POST /api/services/catalog/<service_id>/accounts
+Content-Type: application/json
+
+{ "username": "alice", "password": "optional" }
+```
+
+If `password` is omitted, `AccountManager` generates one with `secrets.token_urlsafe(16)`. The response on HTTP 201 is:
+
+```json
+{ "service_id": "email", "username": "alice", "provisioned": true }
+```
+
+The password is not echoed in the response. To retrieve stored credentials for a provisioned peer, call `GET /api/services/catalog/<id>/accounts/<username>/credentials`.
+
+Internally, `AccountManager.provision(service_id, peer_username, password)`:
+
+1. Resolves the service and its manager via `_resolve_service()`.
+2. Calls the appropriate `_provision_*` method, which delegates to the concrete manager:
+   - `email_manager` → `create_email_user(username, domain, password)`
+   - `calendar_manager` → `create_calendar_user(username, password)`
+   - `file_manager` → `create_user(username, password)`
+3. Stores `{"password": "<value>"}` under `[service_id][peer_username]` in the credentials file.
+4. Returns the credential dict to the caller.
+
+If the underlying manager call returns `False`, `provision()` raises `RuntimeError`. The route handler maps this to HTTP 500.
+
+For email, the domain is read from the service's merged config (`svc['config']['domain']`). If that key is absent, provisioning raises `ValueError` before calling the manager.
+
+### Deprovision flow
+
+```
+DELETE /api/services/catalog/<service_id>/accounts/<username>
+```
+
+`AccountManager.deprovision(service_id, peer_username)`:
+
+1. Calls the appropriate `_deprovision_*` method on the underlying manager.
+2. Removes the peer's entry from the credentials file. If that leaves the service block empty, the service block itself is removed.
+3. Returns `True` if the underlying call succeeded.
+
+The route returns HTTP 200 with `{"message": "..."}` on success, or HTTP 400 if the service does not exist or does not support accounts.
+
+**Peer deletion** calls `AccountManager.deprovision_peer(peer_username)`, which iterates over every service the peer is provisioned on and calls `deprovision()` for each. Failures on individual services are logged and skipped rather than aborting the deletion — the method returns `{service_id: bool}` for every service attempted.
+
+### PIC admin API endpoints for account management
+
+These endpoints are in `api/routes/services.py` and `api/routes/peers.py`.
+
+| Method | Path | Description |
+|---|---|---|
+| `GET` | `/api/services/catalog/<service_id>/accounts` | Return `{"service_id": "...", "accounts": ["alice", "bob"]}` — reads directly from the credentials file. |
+| `POST` | `/api/services/catalog/<service_id>/accounts` | Provision a peer account. Body: `{"username": "...", "password": "..."}` (password optional). Returns HTTP 201 with `{"service_id", "username", "provisioned": true}`. |
+| `DELETE` | `/api/services/catalog/<service_id>/accounts/<username>` | Deprovision the peer's account. Returns HTTP 200 on success, HTTP 400 if the service or username is unknown. |
+| `GET` | `/api/services/catalog/<service_id>/accounts/<username>/credentials` | Return stored credentials for one peer+service pair. Returns HTTP 404 if the peer is not provisioned on that service. Response: `{"service_id", "username", "password"}`. |
+| `GET` | `/api/peers/<peer_name>/service-credentials` | Return filled `peer_config_template` values for all services the peer is provisioned on (see below). |
+
+**Admin UI:** The Email, Calendar, and Files service pages in the admin dashboard each have an **Accounts** tab. From there, admins can provision and deprovision peer accounts, and reveal stored credentials for a provisioned peer. This tab calls the same API endpoints listed above.
+
+### How `peer_config_template` connects to stored credentials
+
+`GET /api/peers/<peer_name>/service-credentials` is the endpoint a peer device calls during first-time setup to configure email, CalDAV, and file sync clients.
+
+The route:
+
+1. Calls `AccountManager.get_all_credentials(peer_name)` → `{service_id: {field: value}}`.
+2. For each service, calls `ServiceRegistry.get_peer_service_info(service_id, peer_name, domain, cred)`.
+3. `get_peer_service_info` iterates over `peer_config_template` and replaces tokens:
+   - `{domain}` → effective cell domain
+   - `{peer.username}` → URL-percent-encoded peer username (safe='')
+   - `{peer.service_credentials.<service_id>.<field>}` → the value from stored credentials
+   - `{config.<key>}` → value from the service's merged config schema
+4. Returns the filled template dict as the value for that service in the response.
+
+Response shape:
+
+```json
+{
+  "peer": "alice",
+  "services": {
+    "email": {
+      "imap_host": "mail.alice.pic.ngo",
+      "username": "alice@alice.pic.ngo",
+      "password": "<stored>"
+    },
+    "files": {
+      "url": "https://files.alice.pic.ngo/dav/alice/",
+      "username": "alice",
+      "password": "<stored>"
+    }
+  }
+}
+```
+
+If a service has no `peer_config_template` in its manifest, `get_peer_service_info` returns `None` and the raw credential dict is used as the fallback.
+
+### Container lifecycle routes
+
+The following PIC API endpoints are available for all services (builtins and store services). These are called by the web UI and can be called directly from the PIC admin API.
+
+| Method | Path | Description |
+|---|---|---|
+| `GET` | `/api/services/catalog/<id>/status` | Return container status. Builtins query the main compose stack; store services query their own compose project. Response includes a `containers` array with one entry per container. |
+| `POST` | `/api/services/catalog/<id>/restart` | Restart the service containers. Builtins restart via the main compose stack; store services restart via their own compose project. |
+| `POST` | `/api/services/catalog/<id>/reconfigure` | Re-render the compose file from the template and re-apply with `up -d` (rolling update). Store services only — builtins are reconfigured through their own settings routes. The request body must include a `compose_template` field containing the new template content. |
+
+### Store service HTTP API
+
+When `accounts.manager` is `"http"`, PIC will call your container's HTTP API for account operations. **HTTP dispatch is not yet wired up in `AccountManager`** — the current dispatch table covers only `email_manager`, `calendar_manager`, and `file_manager` (used by the reference services). Implement this interface now so your service is ready when HTTP dispatch ships.
+
+The base path is `/service-api/accounts` on your container's internal address. There is no authentication on this API — it is reachable only from within the `cell-network` Docker network.
+
+**Create account**
+
+```
+POST /service-api/accounts
+Content-Type: application/json
+
+{ "username": "alice", "password": "auto-generated-by-pic" }
+```
+
+PIC generates the password and passes it to your service. Return HTTP 200 with `{"ok": true}` on success. Return HTTP 400 or 409 with `{"ok": false, "error": "..."}` for expected errors (duplicate username, invalid input). Return HTTP 500 for unexpected internal errors.
+
+**Delete account**
+
+```
+DELETE /service-api/accounts/{username}
+```
+
+Return HTTP 200 with `{"ok": true}` on success. Return HTTP 404 with `{"ok": false, "error": "not found"}` if the account does not exist.
+
+**List accounts**
+
+```
+GET /service-api/accounts
+```
+
+Return `{"accounts": ["alice", "bob"]}` — an array of all provisioned usernames.
+
+---
+
+## 5. Backup integration
+
+Declare `has_storage: true` in `capabilities` and fill in the `backup` block. PIC's `ServiceRegistry.get_backup_plan()` returns the combined backup declarations for all installed services. The backup runner reads from that method.
+
+### Why docker exec instead of bind mounts
+
+The API container only has access to `data/api/` on the host filesystem. Service data (mailboxes, calendar collections, file trees) lives in other containers' volumes. Rather than mount every service volume into the API container — which would require compose changes per service — PIC streams data using `docker exec <container> tar czf - <path>`. This works for any container on the Docker host regardless of how its volumes are configured.
+
+### `volumes` entries
+
+Each object in the `volumes` array describes one directory to capture:
+
+| Field | Description |
+|---|---|
+| `container` | Name of the running container to exec into (e.g. `"cell-notes"`). |
+| `path` | Absolute path inside that container to archive (e.g. `"/data/notes"`). |
+| `name` | Archive filename stem. PIC saves the archive as `<name>.tar.gz` under `service_data/<service_id>/` in the backup directory. |
+
+A service with multiple containers or multiple data directories lists one entry per directory.
+
+**Security note:** The backup commands use `docker exec -- <container> tar -C <path> -czf - .` (note the `--` separator before the container name) to prevent option injection. The container name is also validated against `^[a-zA-Z0-9][a-zA-Z0-9_.-]{0,63}$` before the command is run.
+
+### `config_paths`
+
+Paths in `config_paths` are relative to the PIC project root on the host and are copied directly into the snapshot (no docker exec). Use this for configuration files the service reads at startup, not for user data.
+
+### Full example
+
+```json
+"backup": {
+  "volumes": [
+    {"container": "cell-notes", "path": "/data/notes", "name": "notes_data"}
+  ],
+  "config_paths": ["config/notes"]
+}
+```
+
+This produces one archive `notes_data.tar.gz` (streamed from the `cell-notes` container) plus a direct copy of `config/notes/` from the host.
+
+### Restore
+
+PIC restores each volume entry by piping the archive back via `docker exec -i -- <container> tar -C <path> -xzf -`. The `-C <path>` flag bounds extraction to the declared volume path — the same path used during backup. Archive entries are relative paths (the backup uses `tar -C <path> -czf - .`), so files land in exactly the location declared in the manifest `volumes` entry. The target container must be running at restore time.
+
+---
+
+## 6. Egress routing
+
+When `has_egress` is `true`, the cell admin can assign a specific outbound interface to your service. PIC enforces the selection using `fwmark` rules and policy routing in the `cell-wireguard` container via the `ConnectivityManager`.
+
+The valid values for `egress.allowed` and what they mean:
+
+| Value | Path |
+|---|---|
+| `default` | Default route through the cell's WAN interface (no VPN). |
+| `wireguard_ext` | Traffic leaves through `wg_ext0` (fwmark `0x10`, table 110). Requires the `wireguard-ext` store service. |
+| `openvpn` | Traffic leaves through `tun0` (fwmark `0x20`, table 120). Requires the `openvpn-client` store service. |
+| `tor` | Traffic is redirected to the Tor transparent proxy on port 9040 (fwmark `0x30`, table 130). Requires the `tor` store service. |
+| `sshuttle` | Traffic is redirected to the sshuttle transparent proxy on port 12300 (fwmark `0x40`, table 140). Requires the `sshuttle` store service. |
+| `proxy` | Traffic is redirected to the redsocks transparent proxy on port 12345 (fwmark `0x50`, table 150). Requires the `proxy` store service. |
+
+List only the interfaces that make sense for your service in `allowed`. The `default` value is used when the admin has not changed anything. Always include `default` in `allowed` so the admin has a way to use the normal path.
+
+The egress field in the manifest tells PIC what options to present in the UI. Actual enforcement requires the cell to have the corresponding exit type configured (an OpenVPN config uploaded, a WireGuard external config active, etc.). If the chosen exit is not active, packets will be dropped by the kill-switch FORWARD rule in `cell-wireguard`.
+
+---
+
+## 7. Quick-start example
+
+This section walks through a minimal working example: a static website served from Nginx with no accounts, no backup, and no egress policy.
+
+### `manifest.json`
+
+```json
+{
+  "schema_version": 3,
+  "id": "homepage",
+  "name": "Homepage",
+  "description": "A static homepage served from your cell",
+  "version": "1.0.0",
+  "author": "acme",
+  "kind": "store",
+  "min_pic_version": "1.0",
+
+  "capabilities": {
+    "has_subdomain": true,
+    "has_accounts": false,
+    "has_admin_config": false,
+    "has_storage": false,
+    "has_egress": false,
+    "has_api_hooks": false
+  },
+
+  "subdomain": "home",
+  "extra_subdomains": [],
+  "backend": "cell-homepage:80",
+
+  "containers": ["cell-homepage"],
+
+  "image": "git.pic.ngo/roof/pic-homepage:latest",
+  "container_name": "cell-homepage",
+
+  "volumes": [
+    { "name": "homepage-html", "mount": "/usr/share/nginx/html" }
+  ],
+
+  "env": [],
+
+  "iptables_rules": [
+    {
+      "type": "ACCEPT",
+      "dest_ip": "${SERVICE_IP}",
+      "dest_port": 80,
+      "proto": "tcp"
+    }
+  ],
+
+  "caddy_route": {
+    "subdomain": "home"
+  },
+
+  "compose": null
+}
+```
+
+### What PIC does on install
+
+1. Downloads this manifest from the store index.
+2. Validates every field (image allowlist, volume safety, reserved subdomains, iptables rule format).
+3. Allocates a static IP from the service pool (`172.20.0.20`–`172.20.0.254`).
+4. Writes a Docker Compose override file that starts `cell-homepage` with the allocated IP on `cell-network`.
+5. Runs `docker compose up -d cell-homepage`.
+6. Applies the `iptables_rules` in `cell-wireguard` so peers can reach the container.
+7. Regenerates the Caddyfile so `home.<cell-domain>` proxies to `cell-homepage:80`.
+
+The result is that any WireGuard peer can reach `https://home.alice.pic.ngo/` immediately after installation.
+
+---
+
+## 8. Reference implementations
+
+The `email`, `calendar`, and `files` services in `pic-services/services/` are the canonical examples of a complete store service. They demonstrate the full feature set:
+
+| Service | Notable features demonstrated |
+|---|---|
+| `email` | `has_accounts`, `has_egress`, multi-container (`cell-mail` + `cell-rainloop`), `extra_backends`, custom image baking defaults via Dockerfile |
+| `calendar` | `has_accounts`, CalDAV `peer_config_template`, htpasswd account provisioning |
+| `files` | `has_accounts`, `has_storage`, WebDAV + Filegator `extra_backends`, `backup.volumes` with multiple entries |
+
+When in doubt about how to structure your manifest or compose template, use these as the reference.
+
+---
+
+## 9. Submitting to the store
+
+### Package format
+
+A store service package is a ZIP archive containing:
+
+```
+homepage-1.0.0.zip
+├── manifest.json          (required)
+├── compose-template.yml   (recommended for multi-container services)
+└── install.sh             (optional post-install script)
+```
+
+`install.sh` is executed on the cell host after the container starts. Keep it minimal — initialise data structures, create default config files. Do not use it to install system packages or modify files outside the PIC project root.
+
+### Store index entry
+
+The store index at `https://git.pic.ngo/roof/pic-services/raw/branch/main/index.json` is a JSON array. Each entry looks like:
+
+```json
+{
+  "id": "homepage",
+  "name": "Homepage",
+  "description": "A static homepage served from your cell",
+  "version": "1.0.0",
+  "author": "acme"
+}
+```
+
+PIC fetches the full manifest from `https://git.pic.ngo/roof/pic-services/raw/branch/main/services/{id}/manifest.json` when the admin clicks install.
+
+### Submission process
+
+1. Fork `https://git.pic.ngo/roof/pic-services`.
+2. Create a directory `services/<your-id>/` and add your `manifest.json`.
+3. Open a pull request against `main`.
+
+The review checks the following before merging:
+
+**Security**
+- Image hosted on `git.pic.ngo/roof/*`. No external registries.
+- No volume mounts to system paths or to the PIC project root.
+- `iptables_rules` only declare `ACCEPT` rules (no DROP, no REJECT, no chain redirects).
+- `env` values contain only alphanumeric characters and a small set of safe punctuation.
+- `install.sh` does not call `apt`, `yum`, `curl | bash`, or modify files outside the project.
+
+**Correctness**
+- `subdomain` does not collide with the reserved list or with any existing store service.
+- `backend` points to the declared `container_name`.
+- If `has_accounts: true`, the container responds correctly on all three `/service-api/accounts` endpoints.
+- If `has_storage: true`, every `volumes` entry names a container that is running and a path that exists inside it.
+
+**Quality**
+- `description` is one sentence, no marketing language.
+- `version` is a valid semver string.
+- `config_schema` labels are in plain English, sentence case.
+
+### Versioning

+Increment `version` in `manifest.json` with every change you submit. PIC does not auto-update installed services; the admin manually runs an update. When an update is available, the UI shows the version mismatch between the installed record and the store index.
+
+---
+
+## Appendix: manifest field quick reference

+| `peer_config_template` | if `has_accounts` | |
+| `accounts` | if `has_accounts` | |

+| `backup` | if `has_storage` | |
+| `egress` | if `has_egress` | |

 E2E test: cross-cell routing for a split-tunnel VPN peer.

-is reachable end-to-end via the cell-to-cell link.
+Creates a temporary WireGuard peer on cell2 (the first connected cell), brings up
+a real WireGuard tunnel from the test-runner host, and verifies that cell1 (the
+local cell) is reachable end-to-end via the cell-to-cell link.
 
 Why this test is meaningful
 ---------------------------
-10.0.0.1 is cell1's WireGuard server IP, reachable ONLY inside cell1's
-cell-wireguard Docker container. It is NOT reachable directly from the
-test-runner host (verified: 100% packet loss without VPN).
+Cell1's WireGuard server IP is reachable ONLY inside cell1's cell-wireguard Docker
+container. It is NOT reachable directly from the test-runner host. If a ping to
+that IP succeeds, the full path was taken:
 
-If a ping to 10.0.0.1 succeeds during the test, the full path was taken:
-
-  [test-runner wg-e2e] → 192.168.31.52:51821 → [pic1 cell-wireguard FORWARD]
-  → [cell-to-cell WG tunnel] → [pic0 cell-wireguard] → 10.0.0.1
+  [test-runner wg-e2e] → cell2 WireGuard → [cell-to-cell tunnel] → cell1 WG IP
 
 Prerequisites
 -------------
-  * SSH access to 192.168.31.52 (pic1) as 'roof' with no passphrase
-  * `wg-quick` and `sudo` available on the test runner (pic0)
-  * Both cells must have an active cell-to-cell WireGuard handshake
+  * /home/roof/pic/data/api/cell_links.json must have at least one connected cell
+  * /home/roof/pic/config/wireguard/wg_confs/wg0.conf must exist
+  * SSH access to cell2's LAN IP as 'roof' with no passphrase
+  * `wg-quick`, `dig`, and `sudo` available on the test runner
