Refactor server config: single --config flag replaces --secrets/--mail-perms

- New server/config.mjs loads config.json, resolves secrets path relative
  to config dir, returns users/smtp/mail_perms_path/bind/port
- server/secrets.mjs removed (logic absorbed into config.mjs)
- smtp moves from secrets.json to config.json
- secrets.json now contains only users (pure credentials)
- config.example.json added as reference template
- .gitignore/.npmignore updated to cover config.json and mail-perms.json
- README updated with new setup and flags

 # claude-code-conduit
 
-A supervised action bridge between Claude Code and the host system.
+A supervised action bridge between Claude Code and the host system. Claude requests structured actions; the server applies per-action policies and optionally holds them for human approval before executing.
 
-Claude requests structured actions. The server applies per-action policies:
-- **auto-accept** — executed immediately (e.g. open a file in editor)
-- **auto-deny** — rejected immediately
-- **queue** — held for user approval (e.g. open a browser URL)
+## Concepts
 
-## Setup
+**Actions** are typed verbs with named parameters — not shell commands. The server defines what actions exist and what happens when they are called. Example:
+
+```json
+{ "action": "edit-file", "filename": "/workspace/foo.mjs" }
+```
+
+**Policies** control what happens when an action is requested:
+- `auto-accept` — executed immediately (e.g. open a file in the editor)
+- `auto-deny` — rejected immediately
+- `queue` — held for human approval (e.g. open a browser URL)
+
+**Authentication** uses HMAC-SHA256. Every request is signed with the caller's secret. Secrets live in a JSON file — never in environment variables.
+
+**Users** each have a secret and a `canApprove` list controlling whose queued actions they may approve.
+
+---
+
+## Install
 
 ```bash
+# Global install from Gitea
+npm install -g git+https://gitea.efforting.tech/mikael-lovqvists-claude-agent/claude-code-conduit.git
+
+# Or clone and link locally
+git clone git@git.efforting.tech:mikael-lovqvists-claude-agent/claude-code-conduit.git
+cd claude-code-conduit
 npm install
+npm link
 ```
 
-## Running the server
+### Generate secrets
 
 ```bash
-node server/index.js
-# or
-CONDUIT_PORT=3333 CONDUIT_ROOT=/workspace node server/index.js
+# Create a secrets file with random secrets for each user
+ccc-keygen --create user,agent
+
+# Edit secrets.json to configure who can approve whom:
+# set user.canApprove = ["agent"]
+
+# Produce a filtered file for the agent (e.g. to copy into a Docker container)
+ccc-keygen --filter agent --output agent-secrets.json
 ```
 
-## Using the CLI client
+The full `secrets.json` stays on the host. `agent-secrets.json` goes into the container.
+
+### Create a config file
+
+Copy [`config.example.json`](config.example.json) to `config.json` and edit it:
+
+```json
+{
+    "secrets": "../secrets.json",
+    "mail_perms": "mail-perms.json",
+    "smtp": {
+        "host": "smtp.example.com",
+        "port": 587,
+        "secure": false,
+        "auth": { "user": "relay@example.com", "pass": "<password>" },
+        "from": "agent@example.com"
+    },
+    "bind": "127.0.0.1",
+    "port": 3015
+}
+```
+
+`secrets` and `mail_perms` paths are resolved relative to the config file. `smtp`, `mail_perms`, `bind`, and `port` are all optional.
+
+---
+
+## Running
+
+### Server (host)
 
 ```bash
-# List available actions
-node client/index.js list-actions
-
-# Open a file in the editor (auto-accepted)
-node client/index.js edit-file filename=/workspace/myfile.js
-
-# Open a URL (queued for user approval)
-node client/index.js open-browser url=https://example.com
+ccc-server --config config.json
+ccc-server --config config.json --dry-run
 ```
 
-When a queued action is submitted, the server prints the approve/deny URLs to stdout:
+Server flags:
+| Flag | Env variable | Description |
+|------|-------------|-------------|
+| `--config <path>` | `CONDUIT_CONFIG` | Path to config file (required) |
+| `--dry-run` | — | Log all action invocations but do not execute them |
 
-```
-[QUEUE] New request #a1b2c3d4
-  Action: open-browser
-  Params: {"url":"https://example.com"}
-  Approve: POST /queue/a1b2c3d4.../approve
-  Deny:    POST /queue/a1b2c3d4.../deny
-```
+Server environment variables (override config file values):
+| Variable | Description |
+|----------|-------------|
+| `CONDUIT_PORT` | Port to listen on |
+| `CONDUIT_BIND` | Address to bind to |
+| `CONDUIT_ROOT` | Label printed at startup (informational only — path resolution uses `VOLUME_MAPPING` in `server/helpers.mjs`) |
+
+### Client (container / agent)
 
-User approves via:
 ```bash
-curl -X POST http://localhost:3333/queue/<id>/approve
+ccc-client --secrets agent-secrets.json --user agent --url http://192.168.2.99:3015 '{"action": "list-actions"}'
+ccc-client --secrets agent-secrets.json --user agent '{"action": "edit-file", "filename": "/workspace/foo.mjs"}'
 ```
 
-## Environment variables
+`--secrets`, `--user`, and `--url` can also be set via environment variables:
 
+```bash
+export CCC_SECRETS=/path/to/agent-secrets.json
+export CCC_USER=agent
+export CONDUIT_URL=http://192.168.2.99:3015
+ccc-client '{"action": "list-actions"}'
+```
+
+The JSON payload can be spread across multiple arguments — they are space-joined before parsing:
+
+```bash
+ccc-client '{"action": "edit-file",' '"filename": "/workspace/foo.mjs"}'
+```
+
+### Queue manager (host)
+
+```bash
+ccc-queue --secrets secrets.json --user user --url http://192.168.2.99:3015
+```
+
+Opens an interactive TUI showing pending actions:
+
+```

+
+Client environment variables:
 | Variable | Default | Description |
 |----------|---------|-------------|
-| `CONDUIT_PORT` | `3333` | Server port |
-| `CONDUIT_ROOT` | `/workspace` | Workspace root for path resolution |
-| `CONDUIT_URL` | `http://localhost:3333` | Server URL (client-side) |
+| `CCC_SECRETS` | — | Path to secrets file |
+| `CCC_USER` | — | Username to authenticate as |
+| `CONDUIT_URL` | `http://localhost:3015` | Server URL |
 
-## Adding actions
+---
 
-Edit `server/actions.js`. Each action needs:
-- `description` — shown in list-actions
-- `params` — array of `{ name, required, type }`
-- `policy` — `"auto-accept"` | `"auto-deny"` | `"queue"`
-- `handler(params, helpers)` — async function that performs the action
+## Actions
+
+Query available actions at runtime:
+
+```bash
+ccc-client '{"action": "list-actions"}'
+```
+
+Built-in actions:
+
+| Action | Policy | Params |
+|--------|--------|--------|
+| `list-actions` | auto-accept | — |
+| `edit-file` | auto-accept | `filename` (path) |
+| `open-browser` | queue | `url` (http/https only) |
+| `open-terminal` | queue | `path` (optional, defaults to workspace) |
+| `send-email` | auto-accept | `to`, `subject`, `body`, `topic` |
+| `set-mail-permission` | auto-accept | `target_user`, `to`, `allow` (bool), `topic` (optional — omit to match any topic) |
+| `get-mail-permissions` | auto-accept | `target_user` (optional) |
+
+`send-email` checks that the caller has a mail permission entry matching `(caller, to, topic)` before sending. Permissions are managed via `set-mail-permission`, which requires the caller to have `canApprove` over the target user — so only humans can grant/revoke permissions for agents.
+
+### Adding actions
+
+Edit `server/actions.mjs`. Each entry needs:
+
+```js
+'my-action': {
+    description: 'What this does',
+    params: [{ name: 'foo', required: true, type: 'string' }],
+    policy: 'auto-accept',   // or 'auto-deny' | 'queue'
+    handler: ({ foo }, ctx) => {
+        // ctx = { caller, users, mail_perm_store, mailer_send }
+        // ctx is optional — omit the second argument if you don't need it
+        return { result: foo };
+    },
+},
+```
+
+---
+
+## Path resolution
+
+The server translates container-side paths to host-side paths using the volume map in `server/helpers.mjs`. By default this matches the `docker-compose.yml` layout:
+
+| Container path | Host path |
+|----------------|-----------|
+| `/workspace` | `<CONTAINER_PATH>/workspace` |
+| `/home/claude` | `<CONTAINER_PATH>/claude-home` |
+
+Paths outside known volumes are rejected. Edit `CONTAINER_PATH` and `VOLUME_MAPPING` in `server/helpers.mjs` to match your setup.
+
+---
+
+## Security notes
+
+- Secrets are never passed via environment variables or command line arguments — only via a file
+- HMAC signatures include a timestamp; requests older than 30 seconds are rejected
+- `canApprove` is empty by default — permissions must be explicitly granted
+- Browser URLs are validated to `http`/`https` only before being passed to `xdg-open`
+- All path arguments are resolved against the volume map; traversal outside known volumes is rejected
