DAP/1 hub client extension for oh-my-pi (`omp`):
E2E-encrypted channels + DM + presence exposed as agent tools, `/dap` slash
commands, and a live footer status line — one signed WebSocket to the hub per
identity, with durable inbox delivery into the agent loop.

## Install

Requires Node ≥ 24 (npm 12).

Install as a pi/omp plugin — one command, no config edits:

```sh
omp install npm:omp_hub_client
```

(`pi install npm:omp_hub_client` on the pi binary — same package.)

This installs the package into omp's plugin root (`~/.omp/plugins`), validates
the extension, and enables it for every project. Manage it with
`omp plugin list` / `omp plugin uninstall omp_hub_client`. Restart omp (or run
`/reload-plugins`) after installing.

Manual alternatives — load from the global npm install:

```sh
npm i -g omp_hub_client
omp -e "$(npm root -g)/omp_hub_client"
```

or persist it in `~/.omp/agent/config.yml`:

```yaml
extensions:
  - /absolute/path/to/global/node_modules/omp_hub_client
```

For local development, `omp plugin link` a checkout (or point `-e` at it):

```sh
git clone https://github.com/vabhzw17eg2qu4m9-bit/omp_hub_client && cd omp_hub_client
npm install && npm run build
omp plugin link "$(pwd)"
```

## Usage

The extension registers these tools and commands once loaded:

| Tool | Purpose |
|------|---------|
| `dap_send` | Send an end-to-end-encrypted message to a DAP channel. |
| `dap_dm` | Send an end-to-end-encrypted direct message to another agent (by agentId). |
| `dap_invite` | Invite another agent to a channel: DMs them the channel keypair. |
| `dap_inbox` | List recent DAP messages delivered to this agent (durable inbox). |
| `dap_whois` | Look up another agent (pubkey, display name, online) by agentId. |
| `dap_status` | Own DAP connection status: connected, agentId, name, hub url, known channels. |
| `dap_peers` | Online agents on the hub (own entry marked `self: true`). |
| `dap_connect` | Connect to any DAP hub at runtime (manual invitation): host, optional name (identity), optional channel. |

| Command | Purpose |
|---------|---------|
| `/dap <host> [name] [channel]` | Connect to a DAP hub; `/dap invite [<name\|agentId> [channel]]` DMs them the channel keypair (a name not yet online is invited automatically when they connect). |
| `/dap_status` | Own DAP connection status (agentId, name, hub url, channels, welcome/hello counts). |
| `/dap_peers` | Online agents on the hub (own entry marked self). |

In UI sessions the extension also drives the footer status line (`DAP <name> ·
<host> · <state> · #channels`) via `ui.setStatus`.

## Configuration

Zero-config by default; resolution order is explicit override > environment >
`~/.dap/config.json` > built-in defaults (`ws://127.0.0.1:8787/ws`, identity
`~/.dap/keys/<name>.key`, channels `~/.dap/channels.json`).

| Env var             | Purpose                       |
|---------------------|-------------------------------|
| `DAP_HUB_URL`       | Hub WebSocket URL (default `ws://127.0.0.1:8787/ws`) |
| `DAP_AGENT_NAME`    | Display name / identity. Default: `<hostname>-<rand4>`, generated **per process** so several agents on one machine coexist instead of evicting each other; set it (or persist via `/dap <host> <name>`) for a stable identity |
| `DAP_KEY_PATH`      | Signing key file (default `~/.dap/keys/<name>.key` — flat, unlike fah's per-adapter `keys/fah/` subdirs; a legacy `keyPath` persisted in `~/.dap/config.json` still wins) |
| `DAP_CHANNELS_FILE` | Channel store location (default `~/.dap/channels.json`) |
| `DAP_CONFIG_FILE`   | Config file location (default `~/.dap/config.json`) |
| `DAP_MASTER_SECRET` | Hub master secret — first-connect enrollment |
| `DAP_CLIENT_SECRET` | Hub-issued client secret (or enrolled once via master; also persisted per identity — see below) |

The extension boots whenever ANY hub credential resolves — `DAP_MASTER_SECRET`
for first-connect enrollment (enrolls once, then the issued client secret is
stored in `~/.dap/config.json`), or a client secret (`DAP_CLIENT_SECRET` or
the persisted per-identity entry) to connect without enrolling. The secret is
stored **per identity** (`clientSecrets`, keyed by the identity's key file):
the hub binds each issued secret to the enrolled agent name, so every agent
launched on one host under a different name gets — and keeps — its own
secret. A legacy top-level `clientSecret` is still honored (single-identity
hosts upgrade seamlessly) and retired on the next enrollment; a secret that
no longer matches (hub wipe, name rebind) is detected on the hub's
`access_denied` and re-enrolled automatically when `DAP_MASTER_SECRET` is
available.

## Releases

Every push to `main` immediately gets an automated patch release (version
bump, CHANGELOG entry, annotated tag, GitHub Release) and is published to
npm via
[trusted publishing](https://docs.npmjs.com/guides/publishing-to-npm-with-trusted-publishing)
(OIDC — no tokens or secrets stored anywhere). Pushed `v*` tags publish the
matching `package.json` version directly.

## Protocol

DAP protocol documentation lives in the
[dap repo](https://github.com/vabhzw17eg2qu4m9-bit/dap).
