-**Production-oriented boilerplate for Holepunch / HyperDHT P2P apps.**
+**Decentralized, P2P, Netdata-class real-time monitoring for the Pear / Holepunch ecosystem.**

-Distilled from patterns used in [peardock](https://github.com/snxraven/peardock)-class apps (MIT template — not a copy of peardock’s AGPL sources):
+Each machine runs a lightweight **PearMonitor agent**. A Pear desktop client dials agents by public key and shows fleet + per-node live dashboards. Agents also expose a **Netdata-compatible REST API** (`/api/v1`, `/api/v2`, `/api/v3`) for scripts, Grafana, and Prometheus.
+
+Built from the [pear-app-template](https://github.com/snxraven) HyperDHT + protomux-rpc patterns used by PearDock-class apps (MIT template — not a copy of PearDock’s AGPL sources).

 | Plane | Stack |
 |-------|--------|
 | Transport | **HyperDHT** secret streams (Noise) |
 | RPC | **protomux-rpc** + compact-encoding JSON |
-| Identity | Ed25519 keypairs (server seed + client identity file) |
-| AuthZ | Roles (`viewer` / `operator` / `admin`) + HMAC capabilities + admin seed proof |
-| Desktop | **Pear** (`pear-electron` + `pear-bridge` + `<pear-ctrl>` titlebar) |
-| Server | Node 20+ (systemd unit included) |
-
-The demo product is **PearData**: a multi-peer room with messages, presence, and invite minting. Swap `server/handlers/demo.js` + `server/services/room.js` for your domain.
+| Metrics | 1s collector → tiered buffers → push + query |
+| AuthZ | Roles (`viewer` / `operator` / `admin`) + `pd1.` invites + admin seed |
+| HTTP | Netdata-style REST on `127.0.0.1:19999` |
+| Desktop | **Pear** (`pear-electron` + `pear-bridge` + `<pear-ctrl>`) |

+cd peardata
 npm install

-# Terminal A — server (prints public key)
+# Terminal A — agent (prints public key + REST URL)
 npm run start:server

-# Terminal B — mint an operator invite (optional)
+# Terminal B — REST smoke test
+curl -s http://127.0.0.1:19999/api/v3/info | jq
+curl -s 'http://127.0.0.1:19999/api/v3/data?chart=system.cpu&after=-30&points=30' | jq
+
+# Terminal C — mint an operator invite (optional)
 npm run mint-invite -- operator

-# Terminal C — Pear desktop UI
+# Terminal D — Pear desktop
 npm start
 # or: pear run -d .
 ```

-In the UI, paste the **server public key** (viewer) or a **`pd1.` invite** (elevated role).  
-Paste `SERVER_SEED` from `.env` into “Admin seed” for full admin without an invite.
-
-Drag the **titlebar** to move the window; resize from the edges (`pear.gui.resizable`).

 # Architecture

+PearData is a **decentralized, P2P clone of the Netdata real-time monitoring experience**, built on the same HyperDHT + protomux-rpc patterns as PearDock-class apps (via the pear-app template).
+
 ## Design goals

-1. **No central control plane** — peers dial a public key, not a SaaS tenant.
-2. **Cryptographic identity** — HyperDHT Noise streams authenticate both ends.
-3. **Clear AuthZ** — roles, rate limits, audit, optional allowlist / revoke.
-4. **Shared wire contract** — `shared/*` is the single source of truth for client + server.
-5. **Replaceable domain** — demo room is a thin layer over the session stack.
-6. **Pear-native desktop** — `pear-electron` shell with `<pear-ctrl>` window chrome.
+1. **No central control plane** — dial an agent by Ed25519 public key.
+2. **Instant live truth** — ~1s metric push to connected desktops.
+3. **Dual API** — P2P RPC for the Pear client; Netdata-style REST for scripts/Grafana.
+4. **Clear AuthZ** — viewer (pubkey) vs operator/admin (`pd1.` invite / seed proof).
+5. **Low agent overhead** — Node/`os` + `/proc` collectors, ring buffers, hot-path RPCs.
+6. **Ecosystem-ready** — shared wire contract in `shared/` for PearDock / PearVirt adapters later.
+
+## Mapping to PearDock / template components
+
+| PearDock-class concept | PearData component |
+|------------------------|--------------------|
+| HyperDHT secret stream | `server/server.js` + `client/connection.js` |
+| protomux-rpc methods | `shared/protocol.js` + `server/handlers/monitor.js` |
+| Capability invites (`pd1.`) | `shared/crypto-auth.js` |
+| Roles viewer/operator/admin | `shared/protocol.js` `MethodRoles` + `server/core/acl.js` |
+| Peer policy / revoke | `server/core/peer-policy.js` |
+| Connection manager / multi-peer | `client/manager.js` |
+| Job tray | `server/services/jobs.js` + desktop actions |
+| Domain service | **Metrics pipeline** (`collector` → `store` → `anomaly` → pushes) |
+| Optional HTTP surface | `server/rest/*` (Netdata v1/v2/v3) |

 ## Process model

 | Process | Entry | Responsibility |
 |---------|-------|----------------|
-| **Server** | `server/server.js` or `bin/peardata-server.mjs` | HyperDHT listen, RPC, domain state |
-| **Desktop** | `index.js` → Pear Runtime | Window + HTML UI; dials servers as a client |
-| **Scripts** | `scripts/*` | mint-invite, healthcheck, soak (use client stack) |
+| **Agent** | `server/server.js` / `bin/peardata-server.mjs` | Collect, store, P2P RPC, optional REST |
+| **Desktop** | `index.js` → Pear Runtime | Fleet UI, multi-peer dial, live charts |
+| **Scripts** | `scripts/*` | mint-invite, healthcheck, soak |

-Server and desktop are **independent**. You can run many clients against one server, or headless scripts with no UI.
+Many desktops may dial one agent; one desktop may dial many agents.

-## Server boot
+## Planes

-1. `loadOrCreateKeyPair()` → persist `SERVER_SEED` / `SERVER_PUBLIC_KEY` in `.env`
-2. `initAuthKeys()` → HKDF MAC key for capabilities
-3. `loadPeerPolicy()` → roles / revocations / spent JTIs from `PEARDATA_DATA_DIR`
-4. `dht.createServer().listen(keyPair)`
-5. On connection → revoke check → `PeerSession` → `registerAllHandlers` → peer registry
-6. Banner logs public key + secure/insecure mode
-7. `graceful-goodbye` / SIGINT / SIGTERM drain peers and destroy DHT
+### 1. Control / metadata (RPC)

-## Session middleware (every non-hot RPC)
+Handshake, node info, chart/context catalog, alert config, invites, jobs, ACL.
+
+### 2. High-frequency metrics
+
+- **Ingest:** collector emits sample batches every `PEARDATA_SAMPLE_MS` (default 1000).
+- **Store:** tier0 (1s) + tier1 (downsampled averages).
+- **Push:** `push:metrics` to subscribed peers (protomux-rpc events).
+- **Pull:** `queryData` / REST `/api/v3/data` for history windows.
+
+### 3. Anomaly / health
+
+Threshold engine evaluates each batch; transitions emit `push:anomaly` / `push:alert`; health snapshot on an interval via `push:health`.
+
+### 4. Local REST (optional)
+
+Netdata-compatible HTTP on `127.0.0.1:19999` by default — for local tooling without P2P. Disable with `PEARDATA_REST=0`.

-| State | Meaning |
-|-------|---------|
-| `idle` | Constructed, not dialing |
-| `dialing` | `dht.connect(serverPk)` in flight |
-| `handshaking` | Stream open; `handshake` RPC |
-| `ready` | Authenticated; RPCs allowed |
-| `closed` | Torn down |
-
-`ConnectionManager` tracks multiple peers, active selection, and reconnect (max `PEARDATA_MAX_RECONNECT`).
+Same as the template: rate limit → ACL (`MethodRoles`) → schema validate → handler.  
+Hot methods (`queryData`, `subscribeMetrics`, `ping`, …) skip heavy audit.

 ## Identity planes

 | Plane | Storage | Purpose |
 |-------|---------|---------|
-| **Server keypair** | `.env` (`SERVER_SEED`) | DHT listen address + HMAC root |
-| **Client keypair** | `~/.config/peardata/identity.json` | Stable peerId for AuthZ / revoke |
-| **Capabilities** | Issued as tokens / `pd1.` invites | Role grants with optional expiry & peer bind |
-| **Peer policy** | `data/peer-policy.json` | Registered roles, revocations, spent JTIs |
-| **Audit** | `data/audit.log` | Mutating RPC trail |
+| Agent keypair | `.env` `SERVER_SEED` | DHT address + HMAC root |
+| Client keypair | `~/.config/peardata/identity.json` | Stable peerId |
+| Capabilities | `pd1.` invites / raw tokens | Role grants |
+| Peer policy | `data/peer-policy.json` | Roles, revokes, spent JTIs |
+| Audit | `data/audit.log` | Mutating RPC trail |
+
+## Parent peer (future)
+
+A heavier agent may subscribe to child agents over P2P, downsample into its own store, and expose fleet REST — still no central SaaS. Design leaves room via `stream_path` REST stub and multi-peer desktop manager.

- Never ship `SERVER_SEED` in client bundles or public repos.
- Prefer invites over seed distribution.
- Rotate seed = new public key → all clients re-dial and re-invite.

 export const MethodRoles = Object.freeze({
  // ...
-  listNotes: Roles.viewer,
-  createNote: Roles.operator,
+  listContainers: Roles.viewer,
+  restartCollector: Roles.admin,
 })
 ```

-`Methods` is derived automatically from `MethodRoles` keys.
-
 ### `shared/schema.js`

-Validate `createNote` args (required fields, max lengths).
+Validate args.

-### `server/services/notes.js`
+### `server/services/…` + `server/handlers/monitor.js`

-Domain logic / storage (keep IO out of handlers when possible).
+Register with `session.respond(...)`. Use `{ hot: true }` for high-frequency paths.

-### `server/handlers/notes.js`
+### Client

 ```js
-export function registerNoteHandlers(session) {
-  session.respond('listNotes', async () => ({ notes: [] }))
-  session.respond('createNote', async (args, s) => { /* ... */ })
-}
+await manager.request(Methods.listContainers, {})
 ```

-### `server/rpc/register.js`
+### Docs + tests

-Call `registerNoteHandlers(session)`.
+Update [PROTOCOL.md](./PROTOCOL.md) and add a brittle test.

-### Client / UI
+## Add a REST route
+
+Edit `server/rest/routes.js` — keep Netdata path naming when emulating Agent APIs (`/api/v3/...`).
+
+## Add a job
+
+Register in `server/services/jobs.js` `JOB_HANDLERS`.

-### Tests
+Operators run via `runJob` or future REST function execute.

- Unit for pure helpers + schema
- Integration for the happy path if AuthZ/wire matter

-| **Corestore / Hypercore** | Append-only logs, P2P replication |
-| **SQLite** | Structured queries |
-| **JSON files** under `PEARDATA_DATA_DIR` | Small config (peer-policy already does this) |
-
-Keep RPC handlers thin; put IO in `services/`.
-
-## 5. Binary streams
-
-Peardock-class apps use chunked binary RPC for uploads. Pattern:
-
- methods `binaryStreamOpen` / `Chunk` / `Close` marked `hot: true` in `session.respond`
- skip heavy schema/audit on the hot path
- still enforce ACL + rate limits
-
-Stub hooks exist via `rateLimiter.isStreamMethod`.
-
-## 6. Multi-server fleet
-
-`client/manager.js` already holds many connections + active selection + reconnect:
-
-```js
-await manager.connect(keyOrInviteA, { autoReconnect: true })
-await manager.connect(keyOrInviteB, { autoReconnect: true })
-manager.setActive(keyA)
-await manager.request(Methods.ping, {})
+```
+server/services/collectors/
+  system.js      # default
+  docker.js      # Phase 3
+  peardock.js    # bridge
 ```

-Point UI at a peer list stored in `localStorage` or a file cache for a fuller fleet UX.
+Have `pipeline.js` start each enabled collector; all emit `samples` batches into the same store.

-## 7. Custom desktop UX
+## Parent peer (fleet aggregator)

-| Goal | Touch |
-|------|-------|
-| New screens | `index.html` + `app.js` + `ui/styles.css` |
-| Window size | `package.json` → `pear.gui` |
-| Branding in titlebar | `.app-brand` markup/CSS |
-| Persist UI prefs | replace demo `localStorage` keys |
+1. Parent dials child agents with `ConnectionManager`.
+2. Subscribes to `push:metrics` / periodically `queryData`.
+3. Ingests into local store under namespaced chart ids (`childPk.system.cpu`) or labels.
+4. Exposes `/api/v3/nodes` with multiple entries + `/api/v3/data` across nodes.

-Preserve drag / `pear-ctrl` behavior — [DESKTOP.md](./DESKTOP.md).
+## PearDock / PearVirt hooks

-## 8. Desktop packaging
+- Prefer **RPC adapters** over scraping: call dock/virt methods, map to PearData contexts.
+- Keep AGPL boundaries clean — depend on public APIs / your own MIT bridges.

-This template ships the **Pear** GUI path (`pear run`). For Electron-forge / bare-standalone multi-arch releases, copy more complex packaging scripts from a production app (forge config, make scripts) once your protocol stabilizes.
+## Desktop chrome

-## 9. Checklist for a new product
+Keep `<pear-ctrl>`, titlebar drag regions, and `pear.gui.resizable`. See [DESKTOP.md](./DESKTOP.md).

- [ ] `npm run rename -- …`
- [ ] Replace demo handlers + services

 # Getting started

-## Prerequisites
+## Requirements

-| Tool | Required | Notes |
-|------|----------|--------|
-| **Node.js ≥ 20** | Yes | Server + tests |
-| **npm** | Yes | Install deps |
-| **[Pear](https://docs.pears.com) CLI** | For desktop UI | Run `pear` once to bootstrap the runtime |
-| UDP / network | For real peers | HyperDHT hole-punching |
+- Node.js **≥ 20**
+- Pear runtime (for desktop): install via Holepunch/Pear docs
+- Linux recommended for full net/disk `/proc` collectors (macOS gets CPU/RAM/load)

 ## Install

 ```bash
-git clone <your-fork-or-template-url> my-app
-cd my-app
+cd peardata
 npm install
-cp .env.example .env   # optional; server auto-writes seed on first boot
 ```

-## Run the server
+Copy env template if needed:
+
+```bash
+cp .env.example .env
+```
+
+## Run the agent

 ```bash
 npm run start:server
-# alias: npm run server
 ```

-On first boot the server appends to `.env`:
+Banner shows:

-```
-SERVER_SEED=<64 hex secret>
-SERVER_PUBLIC_KEY=<64 hex public>
+- **publicKey** — dial this from the desktop (viewer)
+- **rest** — e.g. `http://127.0.0.1:19999/api/v3/info`
+- **admin** — use `SERVER_SEED` from `.env` or mint `pd1.` invites
+
+Agent persists identity in `.env` on first boot.
+
+### REST smoke tests
+
+```bash
+curl -s http://127.0.0.1:19999/api/v3/info
+curl -s http://127.0.0.1:19999/api/v1/charts | head
+curl -s 'http://127.0.0.1:19999/api/v3/data?chart=system.cpu&after=-60&points=60'
+curl -s 'http://127.0.0.1:19999/api/v3/allmetrics?format=prometheus' | head
 ```

-**Treat `SERVER_SEED` like a root password.** Anyone with it can mint admin proofs and capabilities.
+Disable REST: `PEARDATA_REST=0`.

-Banner output shows the public key clients dial, for example:
+## Mint an invite

-```
-Client → dial <SERVER_PUBLIC_KEY>
+```bash
+npm run mint-invite -- operator
+# → pd1.…
 ```

-Leave this process running while clients connect.
+Share the invite string. Recipients paste it into the desktop connect box.

-## Run the desktop UI
+## Run the desktop

 ```bash
 npm start
-# or: npm run dev
-# or: pear run -d .
+# pear run -d .
 ```

-### Desktop window chrome
+1. Paste agent public key or `pd1.` invite  
+2. Optional: paste `SERVER_SEED` for admin  
+3. Connect → live overview + charts  
+4. Admin: **Mint invite**

-The Pear UI uses a custom titlebar:
-
-| Piece | Behavior |
-|-------|----------|
-| `<pear-ctrl>` | Platform window controls (macOS traffic lights / Windows & Linux min·max·close) |
-| `#titlebar` | `-webkit-app-region: drag` — drag to move the window |
-| Interactive children | `no-drag` so buttons and chips stay clickable |
-| `pear.gui.resizable` | Edge/corner resize (`true` by default) |
-| `minWidth` / `minHeight` | 720 × 480 floor |
-
-Full details: [DESKTOP.md](./DESKTOP.md).
-
-## Connect as admin (dev)
-
-1. Start the Pear UI: `npm start`
-2. Paste `SERVER_PUBLIC_KEY` into **Server / invite**
-3. Paste `SERVER_SEED` into **Admin seed**
-4. Optionally set a **Display name**
-5. Click **Connect** → role badge should show `admin`
-
-The seed never goes over the wire as plaintext — the client sends an HMAC **admin proof**.
-
-## Connect via invite
+## systemd (Linux)

 ```bash
-# Persistent operator invite (default)
-npm run mint-invite -- operator
-
-# 7-day operator invite (ttl in ms)
-npm run mint-invite -- operator 604800000
-
-# Admin invite
-npm run mint-invite -- admin
-```
-
-Stdout prints a `pd1.…` string. Paste it into the UI connect field (no seed needed).
-
-You can also mint from a connected admin session with **Mint invite** in the UI.
-
-## Viewer-only
-
-Paste only the public key. You can:
-
- `listMessages`, `getPresence`, `getServerInfo`, `setDisplayName`, `ping`
-
-You cannot:
-
- `postMessage` (needs `operator+`)
- `clearMessages`, `mintInvite`, `listPeers`, `revokePeer` (needs `admin`)
-
-Unless you raise `PEARDATA_DEFAULT_ROLE` (not recommended for multi-user hosts).
-
-## Quick verification
-
-```bash
-npm test
-SKIP_INTEGRATION=1 npm test   # unit only
-
-# With server running:
-export SERVER_PUBLIC_KEY=…    # from .env
-export SERVER_SEED=…          # optional but enables admin dial
-npm run healthcheck
-npm run soak                  # optional load exercise
-```
-
-## Environment knobs (summary)
-
-| Variable | Purpose |
-|----------|---------|
-| `SERVER_SEED` / `SERVER_PUBLIC_KEY` | Server identity |
-| `PEARDATA_DEFAULT_ROLE` | Baseline role (`viewer` default) |
-| `PEARDATA_ADMIN_KEYS` | Peer pubs always admin |
-| `PEARDATA_INSECURE_OPEN_ADMIN` | Dev only — all peers admin |
-| `PEARDATA_ALLOWLIST` | If set, only listed / registered peers |
-| `PEARDATA_DATA_DIR` | Peer policy + audit log directory |
-| `PEARDATA_RATE_LIMIT_RPM` | Per-peer RPC budget |
-| `PEARDATA_MAX_MESSAGES` | Demo room history cap |
-| `PEARDATA_MAX_RECONNECT` | Client reconnect tries |
-| `LOG_LEVEL` / `LOG_JSON` | Logging |
-
-Full table: [CONFIGURATION.md](./CONFIGURATION.md).
-
-## Rebrand for a new product
-
-```bash
-npm run rename -- my-app MyApp
-npm install
-npm test
-```
-
-Rewrites package name, protocol id, env prefixes, invite prefix (`pd1.` → derived), product strings, and renames the server binary / systemd unit. Review `git diff` after.
-
-## systemd
-
-```bash
-# Install tree to /opt/peardata (example)
 sudo mkdir -p /opt/peardata
-sudo rsync -a --exclude node_modules --exclude .git ./ /opt/peardata/
-cd /opt/peardata && sudo npm install --omit=dev
-
+sudo rsync -a ./ /opt/peardata/ --exclude node_modules
+cd /opt/peardata && sudo npm ci --omit=dev
 sudo cp deploy/peardata.service /etc/systemd/system/
-# Edit WorkingDirectory, EnvironmentFile, ReadWritePaths if paths differ
 sudo systemctl daemon-reload
 sudo systemctl enable --now peardata
-sudo journalctl -u peardata -f
+journalctl -u peardata -f
 ```

-The unit sets `NoNewPrivileges`, `ProtectSystem=strict`, and writable paths for `data/` + `.env`.
+Ensure `ReadWritePaths` can write `/opt/peardata/data` and `.env`.
+
+## Roles cheat sheet
+
+| Goal | Action |
+|------|--------|
+| Read-only monitoring | Dial pubkey only |
+| Ack alerts / run jobs | `pd1.` operator invite |
+| Mint invites / revoke | Admin seed or admin invite |

 ## Troubleshooting

-| Symptom | What to check |
-|---------|----------------|
-| `Connection timeout` | Server running? Correct 64-hex key? Firewall / UDP? |
-| `PERMISSION_DENIED` on send | Role is viewer — use invite or admin seed |
-| `Rate limit exceeded` | Raise `PEARDATA_RATE_LIMIT_RPM` or slow clients |
-| Window won’t drag | Titlebar drag CSS; don’t cover bar with full-screen `no-drag` overlay |
-| Window won’t resize | `pear.gui.resizable` must be true; try edges not just corners |
-| No `<pear-ctrl>` buttons | Running under Pear (`pear run`)? Element is runtime-provided |
-| Integration test fails in CI | Set `SKIP_INTEGRATION=1` or allow UDP |
-| Seed regenerated every boot | `.env` not writable / wrong cwd |
+| Symptom | Check |
+|---------|-------|
+| REST connection refused | Agent running? `PEARDATA_REST` not `0`? Port free? |
+| Desktop can’t dial | Firewall / DHT; same machine should work; wait for punch |
+| Empty net/disk charts | Non-Linux host — expected until platform collectors land |
+| `PERMISSION_DENIED` | Need higher role invite or admin seed |
+| Integration tests hang | `SKIP_INTEGRATION=1 npm test` on restricted networks |

 # Protocol

-## Constants
+Wire contract for PearData P2P RPC. Source of truth: `shared/protocol.js`, `shared/schema.js`, `shared/metrics.js`.
+
+## Identity

 | Constant | Value |
-|----------|--------|
-| `PROTOCOL` | `peardata/rpc` |
-| `PROTOCOL_VERSION` | `1` |
-| `APP_NAME` | `peardata` |
-| `APP_VERSION` | `0.1.0` (keep in sync with package where useful) |
-| Encoding | compact-encoding JSON (`shared/encodings.js`) |
-| Schema | lightweight validators (`shared/schema.js`) `SCHEMA_VERSION=1` |
+|----------|-------|
+| Protocol id | `peardata/rpc` |
+| Protocol version | `1` |
+| Invite prefix | `pd1.` |
+| Default role | `viewer` |

-Bump `PROTOCOL_VERSION` on breaking request/response shapes. Additive methods may land without a bump if clients ignore unknown methods.
-
-After `npm run rename`, `PROTOCOL` becomes `<slug>/rpc` and invite prefix is regenerated.
-
-## Transport
-
-1. Client opens HyperDHT secret stream to server public key (Noise, mutual key auth).
-2. `ProtomuxRPC` is attached with `protocol: PROTOCOL` and shared encodings.
-3. Client calls `handshake` before other RPCs (connection helper does this automatically).
-4. Server may `push` events on named channels.
+Bump `PROTOCOL_VERSION` on breaking argument/result shapes.

 ## Roles

-| Role | Intent |
-|------|--------|
-| `viewer` | Read-only |
-| `operator` | Mutate domain data |
-| `admin` | Invite mint, clear, revoke, config |
+| Role | Rank | Typical access |
+|------|------|----------------|
+| `viewer` | 1 | Read metrics, subscribe, list alerts |
+| `operator` | 2 | Ack/silence alerts, run jobs, set alert config |
+| `admin` | 3 | Mint invites, revoke peers, export snapshot |

-Hierarchy: `admin > operator > viewer` (`roleAllows`).
-
-Unknown methods default to **admin** required in `assertAllowed` if missing from `MethodRoles` — always register new methods.
+Auth modes at handshake: public key (viewer), capability token / `pd1.` invite, admin seed proof, allowlist.

 ## Methods

-| Method | Min role | Request args | Response (summary) |
-|--------|----------|--------------|--------------------|
-| `handshake` | viewer | `clientName`, `clientVersion`, optional `capability`, `adminProof` | role, auth, versions, features |
-| `ping` | viewer | `{}` | `{ ok, pong, peerId }` |
-| `getServerInfo` | viewer | `{}` | app, versions, host, peer count |
-| `getAuthStatus` | viewer | `{}` | peerId, role, authMode, displayName |
-| `listMessages` | viewer | `{ limit? }` | `{ messages: [...] }` |
-| `getPresence` | viewer | `{}` | `{ peers: [...] }` |
-| `postMessage` | operator | `{ text }` (1–2000 chars) | created message |
-| `setDisplayName` | viewer | `{ name }` (1–40 chars) | updated label |
-| `clearMessages` | admin | `{}` | success + system push |
-| `mintInvite` | admin | `{ role?, ttlMs?, peerId?, alias? }` | `invite` (`pd1.…`), jti, exp |
-| `listPeers` | admin | `{}` | live + policy peers |
-| `revokePeer` | admin | `{ peerId }` (64 hex) | success; target dropped |

-  "serverTime": 0,
-  "auth": { "mode": "capability", "role": "operator" },
-  "features": { "hmacAuth": true, "invites": true, "room": true }
-}
-```
+### Metrics discovery & query

-### Auth modes (`auth.mode` / `session.authMode`)
+| Method | Role | Args | Result |
+|--------|------|------|--------|
+| `listContexts` | viewer | — | Context catalog |
+| `getContext` | viewer | `{ id }` | Charts in context |
+| `listCharts` | viewer | — | Netdata-ish chart map |
+| `getChart` | viewer | `{ id }` | Chart summary |
+| `queryData` | viewer | `{ chart, after, before, points, group, tier }` | Time series |
+| `getAllMetrics` | viewer | `{ format: json\|prometheus\|shell }` | Latest export |

-| Mode | How obtained |
-|------|----------------|
-| `viewer` | Default after connect with no grant |
-| `capability` | Valid capability / invite |
-| `seed` | Valid admin proof from `SERVER_SEED` |
-| `allowlist` / registered | Elevated via policy / admin keys (implementation in ACL + policy) |
+`after` / `before`: absolute unix seconds, or relative (negative = relative to `before`/`now`), Netdata-style.

-Exact labels depend on handshake path; UI shows `authMode` from `getAuthStatus`.

+| `mintInvite` | admin |
+| `listPeers` | admin |
+| `revokePeer` | admin |

+| `push:alert` | Alert transition |
+| `push:health` | `HealthSnapshot` |
+| `push:job` | `JobRecord` |
+| `push:system` | Generic notices |
+
+## Errors
+
+Handlers throw `Error` with `.code`:
+
+| Code | Meaning |
 |------|---------|
-| `push:message` | `{ id, peerId, displayName, text, ts }` |
-| `push:presence` | `{ peers: [...] }` |
-| `push:system` | `{ type, ... }` e.g. `{ type: "cleared" }` |
-
-Registered via `rpc.event` / `session.push`. Client `connection.js` binds all `Pushes` values.
-
-## Invites
-
-Envelope: `pd1.` + base64url(JSON):
-
-```json
-{
-  "v": 1,
-  "publicKeyHex": "<server>",
-  "capability": "<token>",
-  "role": "operator",
-  "jti": "...",
-  "expiresAt": null
-}
-```
-
-Capability token: `base64url(payload).base64url(HMAC-SHA256)`.
-
-Payload fields (canonical order for MAC): `v`, `role`, `peerId`, `exp`, `jti`, `iat`.
-
-### Connection input classification
-
-`classifyConnectionInput(string)` accepts:
-
-| Input | Kind |
-|-------|------|
-| 64 hex chars | `publicKey` |
-| `pd1.…` | `invite` (extracts key + capability) |
-| other | error |
-
-## Error codes
-
-| Code | When |
-|------|------|
-| `RATE_LIMIT_EXCEEDED` | Peer over RPM budget |
-| `PERMISSION_DENIED` | Role too low for method |
-| `INVALID_ARGS` | Schema validation failed |
-| `CONNECTION_TIMEOUT` | Client dial timeout |
-| `RPC_ERROR` | Generic client-normalized failure |
-| `UNKNOWN_ERROR` | Unclassified server handler error |
-
-Clients should read `error.code` when present (`client/errors.js` preserves codes).
+| `PERMISSION_DENIED` | Role too low |
+| `RATE_LIMIT_EXCEEDED` | RPM exceeded |
+| `INVALID_ARGS` | Schema failure |
+| `NOT_CONNECTED` | Client-side |
+| `CAPABILITY_*` | Invite/token issues |

 ## Versioning policy

-1. Document every method in this file.
-2. Add `MethodRoles` entry before implementing handlers.
-3. Add `validateMethodArgs` case for mutating methods.
-4. Add brittle tests for pure helpers; integration test for critical paths.
-5. Bump `PROTOCOL_VERSION` when existing response shapes break.
-6. Bump `SCHEMA_VERSION` when validation semantics change meaningfully.
+1. Additive methods/fields: no version bump if old clients ignore unknowns.
+2. Rename/remove/change meaning: bump `PROTOCOL_VERSION`; reject or compat-negotiate in handshake.
+3. REST API versions (`v1`/`v2`/`v3`) are independent of RPC version but share the store.

+# REST API (Netdata-compatible)
+
+PearMonitor agents expose an optional HTTP API modeled on **Netdata Agent** endpoints (`/api/v1`, `/api/v2`, `/api/v3`).
+
+Default bind: `http://127.0.0.1:19999` (Netdata’s classic port).  
+Disable: `PEARDATA_REST=0`.  
+Bind all interfaces (careful): `PEARDATA_REST_HOST=0.0.0.0`.
+
+This is a **compatibility layer**, not a byte-for-byte Netdata clone. Core query/metadata paths are implemented for scripts, Grafana, and Prometheus scrapers.
+
+## Quick examples
+
+```bash
+# Agent info
+curl -s http://127.0.0.1:19999/api/v3/info | jq
+
+# Chart catalog (v1 style)
+curl -s http://127.0.0.1:19999/api/v1/charts | jq '.charts | keys'

+- **P2P remains the secure remote path** (Noise + roles).
+- If you bind `0.0.0.0`, put REST behind a firewall, reverse proxy, or Holesail tunnel — do not expose raw metrics to the internet.
+- Future: optional bearer gate (`/api/v3/bearer_protection` parity).
+
+## CORS
+
+`Access-Control-Allow-Origin` defaults to `*` (override with `PEARDATA_REST_CORS`).

+# PearData Roadmap
+
+Phased plan from MVP agent → Netdata-class fleet observability on pure P2P.
+
+## Guiding principles
+
+1. **Instant value** — connect a pubkey, see live charts in seconds.
+2. **Agent efficiency** — stay in Netdata’s ballpark for CPU/RAM overhead.
+3. **PearDock patterns** — HyperDHT identity, protomux-rpc, roles, `pd1.` invites.
+4. **Dual access** — P2P desktop + Netdata-style REST (`/api/v1|v2|v3`).
+5. **Ecosystem glue** — ready for PearDock / PearVirt / HoneyPeer / BareOS later.
+
+---
+
+## Phase 0 — Foundation ✅ (this repo)
+
+| Item | Status |
+|------|--------|
+| Copy pear-app-template → PearData rebrand (`pd1.`, `PEARDATA_*`, `peardata/rpc`) | Done |
+| Shared protocol + schema + metrics catalog | Done |
+| Agent collector (CPU/RAM/load/net/disk/processes) @ ~1s | Done |
+| In-memory tiered store (1s + downsample) | Done |
+| Threshold anomaly engine + health | Done |
+| P2P RPC surface (query, subscribe, alerts, jobs, ACL) | Done |
+| Netdata-compatible REST v1/v2/v3 (local :19999) | Done |
+| Pear desktop fleet overview + live canvas charts | Done |
+| Docs: architecture, protocol, data model, REST, roadmap, tech choices | Done |
+| systemd unit + CI skeletons | Done |
+
+**MVP acceptance criteria**
+
+- [x] Agent exposes metrics over P2P by public key
+- [x] Desktop connects to one+ agents and shows live CPU/RAM/net/disk
+- [x] REST `/api/v3/data?chart=system.cpu&after=-60` returns series
+- [x] Viewer vs admin (pubkey / seed / `pd1.` invite)
+- [x] Simple threshold anomalies pushed to clients
+
+---
+
+## Phase 1 — Hardening & UX (next)
+
+- Persistent client peer bookmarks + aliases in desktop
+- Multi-peer compare mode (overlay 2–4 nodes on one chart)
+- Reconnection / offline banners with last-known samples
+- Agent process title / `peardata-agent` binary naming polish
+- Expand collectors: per-core CPU, per-iface net, mount disk space
+- Alert silence TTL auto-reenable
+- brittle tests for collector, store query, REST routes
+- One-line install script (`curl | bash`) for Linux agents
+
+---
+
+## Phase 2 — Storage & history (HyperDB)
+
+See **[STORAGE-HYPERDB.md](./STORAGE-HYPERDB.md)** for the full design (from Holepunch `hyperdb` / workshop / Autobase patterns).
+
+- HyperDB (bee + Corestore) for metadata, alerts, peer-links, **warm** downsampled points
+- Keep memory ring for hot 1s path; do **not** tx every sample into HyperDB
+- Hyperswarm `store.replicate` for linked-node / desktop seed sync
+- Configurable retention (hours@1s memory, days@1m HyperDB, weeks@1h)
+- Historical query: memory miss → HyperDB range
+- Optional later: Autobase multi-writer parents; Rocks engine for local-only speed
+- Export snapshot job → JSON / Prometheus remote write (optional)
+
+---
+
+## Phase 3 — Discovery & apps
+
+- Docker / container auto-discovery (cgroup + Docker API)
+- Common service collectors (nginx, postgres, redis) as plugins
+- PearDock integration: container metrics from dock peers
+- PearVirt / BareOS node metric adapters
+- Holesail optional expose of REST UI per agent
+
+---
+
+## Phase 4 — Smarter anomalies & fleet
+
+- Anomaly scoring + chart highlighting in UI
+- Lightweight ML job (`runJob` retrain) — start with streaming z-score / k-means
+- Fleet-wide composite views and correlation (`/api/v3/weights` depth)
+- Parent peer aggregation (P2P “parent” without central SaaS)
+- Push notifications (desktop + optional webhook)
+
+---
+
+## Phase 5 — Product polish
+
+- Signed release artifacts (agent + Pear desktop)
+- Role templates (viewer / SRE operator / admin)
+- Plugin SDK documentation
+- Grafana datasource (REST) cookbook
+- HoneyPeer presence for agent directory (opt-in)
+
+---
+
+## Non-goals (for now)
+
+- Replacing Netdata Cloud SaaS multi-tenant product
+- Full byte-identical Netdata internal DB format
+- Shipping a browser-only public dashboard without auth by default (REST stays localhost unless explicitly bound)
+
+---
+
+## Milestone checklist (operators)

+| M5 | Parent peer rolling up a homelab fleet |

+## REST API exposure
+
+- Default bind is **localhost only** (`127.0.0.1:19999`).
+- REST is intentionally open on that bind (Netdata-agent style) — **do not** set `PEARDATA_REST_HOST=0.0.0.0` without a firewall, reverse proxy, or Holesail tunnel.
+- Prefer **P2P + roles** for remote multi-operator access; use REST for local scrapers/Grafana.
+
 ## Production checklist

 - [ ] Never set `PEARDATA_INSECURE_OPEN_ADMIN` outside local demos
 - [ ] Keep `PEARDATA_DEFAULT_ROLE=viewer`
- [ ] Prefer invites over sharing `SERVER_SEED`
+- [ ] Prefer `pd1.` invites over sharing `SERVER_SEED`
 - [ ] Use short `ttlMs` for high-privilege invites when practical
 - [ ] Set `PEARDATA_ALLOWLIST` if only known operators should dial
+- [ ] Keep REST on localhost unless explicitly secured
 - [ ] Back up `SERVER_SEED` offline; rotate by redeploying a new keypair (clients must re-dial)
 - [ ] Persist `data/` with mode `0700`; `audit.log` may contain peer ids
 - [ ] Run under systemd with `ProtectSystem` / `NoNewPrivileges` (see `deploy/`)

+# HyperDB storage & linked-node sync
+
+How PearData should adopt Holepunch’s **HyperDB + Corestore + Hyperswarm (+ Autobase)** stack for durable storage and P2P sync between linked agents — based on patterns in local clones under `holepunchto_repos` (`hyperdb`, `hyperdb-workshop`, `hyperdb-autobase-workshop`, `corestore`, `hyperswarm`, `autobee`, `pear-hyperdb`).
+
+## Why HyperDB (not “just SQLite”)
+
+| Need | HyperDB fit |
+|------|-------------|
+| Typed collections + indexes | Hyperschema + `@ns/collection` + secondary indexes |
+| Local high-perf | `HyperDB.rocks(path, def)` |
+| P2P replicate | `HyperDB.bee(hypercore, def, { autoUpdate })` over Corestore |
+| Multi-writer HA parents | Autobase whose **view** is HyperDB (`extension: false`) |
+| Same query API local + remote | Workshops prove one `Registry` class works for both |
+
+PearData’s current `server/services/store.js` is an **in-memory ring**. HyperDB replaces durability + sync; the in-memory tier stays as the **hot 1s path**.
+
+## Stack mapping (from Holepunch repos)
+

+```
+
+| Component | Repo pattern | PearData use |
+|-----------|--------------|--------------|
+| **Hyperschema + hyperdb/builder** | `hyperdb-workshop/build.js` | `spec/` codegen for collections |
+| **HyperDB.bee** | workshop `Registry` | Replicable agent DB |
+| **HyperDB.rocks** | `hyperdb` README | Optional local-only fast index |
+| **Corestore** | workshop `bin.js` | Named cores: `metrics-meta`, `alerts`, … |
+| **Hyperswarm** | `swarm.join(discoveryKey)` + `store.replicate(conn)` | Link nodes / seed DB |
+| **protomux-rpc** | already in PearData | Control plane (unchanged) |
+| **Autobase + hyperdispatch** | `hyperdb-autobase-workshop` | Multi-writer **parent** / HA registry |
+| **autobee** | experimental multiwriter bee | Alternative later; prefer Autobase+HyperDB view for now |
+| **pear-hyperdb** | Pear-shaped Model wrapper | Optional UX for desktop-local rocks |
+
+## Critical design rule: don’t put 1s samples in HyperDB txs
+
+HyperDB is an **indexable document DB** (put/get/find + flush). Writing every chart every second as HyperDB transactions will:
+
+- Amplify Rocks/Bee write cost
+- Create huge replication chatter
+- Fight Netdata-class overhead goals
+
+**Split planes:**
+
+| Plane | Storage | Sync |
+|-------|---------|------|
+| **Hot live (≤1h @ 1s)** | Memory ring (current) | P2P `push:metrics` (current) |
+| **Warm history (downsampled)** | Hypercore append **or** HyperDB rows keyed `(chart, tsBucket)` | Corestore replicate |
+| **Metadata** (peers, alerts, labels, jobs, ACL cache) | **HyperDB** | Corestore replicate |
+| **Fleet / parent consensus** | Autobase → HyperDB view | Swarm on autobase discoveryKey |
+
+## Proposed HyperDB schema (`@peardata/*`)
+
+Modeled after workshop `build.js` namespaces.
+
+### Collections
+
+```text
+@peardata/node
+  key: nodeId (string / pubkey hex)
+  fields: hostname, platform, arch, cpus, agentVersion, labels{}, updatedAt
+
+@peardata/peer-link
+  key: [localNodeId, remotePublicKey]
+  fields: role, alias, discoveryKey?, linkedAt, lastSeen, syncMode (push|pull|both)
+
+@peardata/alert-config
+  key: id
+  fields: chart, dimension, warn, crit, comparator, enabled, info
+
+@peardata/alert-event
+  key: [id, ts]   # or ulid
+  fields: severity, value, threshold, message, cleared
+
+@peardata/metric-point   # WARM tier only (e.g. 1m buckets)
+  key: [chart, ts]
+  fields: context, values{} (map), tier
+
+@peardata/job
+  key: id
+  fields: name, status, startedAt, finishedAt, result?
+```
+
+### Indexes
+
+```text
+@peardata/node-by-hostname          → node.hostname
+@peardata/peer-link-by-remote       → peer-link.remotePublicKey
+@peardata/alert-event-by-chart      → alert-event.chart + ts
+@peardata/metric-point-by-context   → metric-point.context + ts
+```
+
+Rebuild with:
+
+```bash
+node scripts/build-db.js   # Hyperschema + HyperDB.toDisk → spec/
+```
+
+## Agent integration shape
+
+Follow `hyperdb-workshop` / `pear-hyperdb` Model pattern:
+
+```text
+server/
+  db/
+    build.js              # schema codegen
+    spec/hyperschema/
+    spec/hyperdb/
+    model.js              # PearDataModel: putNode, linkPeer, queryWarm, …
+    replicate.js          # Hyperswarm join + store.replicate
+  services/
+    store.js              # HOT memory (keep)
+    store-hyperdb.js      # WARM + metadata facade used by queryData/REST
+```
+
+### Boot (single-writer agent — Phase 2)
+
+```js
+const store = new Corestore(dataDir + '/corestore')
+const swarm = new Hyperswarm({ keyPair: await store.createKeyPair('swarm') })
+swarm.on('connection', (conn) => store.replicate(conn))
+
+const metaCore = store.get({ name: 'peardata-meta' })
+const db = HyperDB.bee(metaCore, spec, { autoUpdate: true })
+
+// announce for linked peers / desktop seeders
+swarm.join(metaCore.discoveryKey, { server: true, client: true })
+```
+
+Collector path:
+
+1. Ingest → memory tier0 (unchanged)
+2. Every N samples → downsample → `tx.insert('@peardata/metric-point', …); tx.flush()`
+3. Alert transitions → `alert-event` collection
+4. `queryData` / REST: memory first, then HyperDB range scan for older windows
+
+### Auth note
+
+HyperDB replication shares **capability to read the core**, not PearData RPC roles. Keep:
+
+- **Noise + MethodRoles** for mutating RPC (`setAlertConfig`, `runJob`)
+- Replication topic optionally gated (only invite-linked peers get discoveryKey / capability)
+- Do **not** announce writable cores to the public swarm without encryption / allowlist
+
+## Linked nodes: sync modes
+
+PearData “links” are first-class `@peardata/peer-link` rows + swarm topics.
+
+| Mode | Behavior |
+|------|----------|
+| **Pull** | Local agent opens remote DB by key (`HyperDB.bee(store.get({ key }), spec, { writable: false, autoUpdate: true })`) and replicates |
+| **Push** | Remote peers allowed to replicate our meta/warm cores (seed) |
+| **Both** | Mutual swarm join (homelab mesh) |
+| **Parent aggregate** | Parent pulls many children; stores namespaced copies or Autobase fleet view |
+
+Discovery:
+
+1. Desktop/admin mints link → stores remote pubkey + optional `dbKey` (z32/hex)
+2. Agent joins `discoveryKey` of that core
+3. On connection: `store.replicate(conn)` (workshop pattern)
+4. `clone.watch` / `autoUpdate` refreshes HyperDB indexes for REST/RPC queries
+
+This is the same pattern as workshop §3.1 Lookups — **read path is swarm + HyperDB**, not constant RPC polling.
+
+## Parent / HA (Phase 4) — Autobase workshop
+
+When you need multi-writer fleet registry or HA parents:
+
+- Autobase bootstrap key shared across parent instances
+- `open: (store) => HyperDB.bee(store.get('db-view'), spec, { extension: false, autoUpdate: true })`
+- hyperdispatch ops: `add-writer`, `put-alert`, `put-link`, `ingest-rollup`
+- RPC (existing PearData / workshop) appends ops; apply mutates HyperDB view
+- Clients dial **any** writer; view key stays stable
+
+Do **not** “backup” by copying Corestore folders (workshop warning). Rotate writers via Autobase instead.
+
+## What stays on protomux-rpc
+
+| Keep on RPC | Why |
+|-------------|-----|
+| Live `push:metrics` | Sub-second UX; not DB-shaped |
+| `subscribeMetrics` / handshake / ACL | Session security |
+| `runJob`, mintInvite | Mutating control |
+| On-demand `queryData` for hot window | Memory path |
+
+| Move to HyperDB (+ replicate) | Why |
+|-------------------------------|-----|
+| Peer links, aliases, labels | Shared fleet truth |
+| Alert config + history | Durable, queryable |
+| Warm/cold metric buckets | History without central server |
+| Node inventory | Parent `/api/v3/nodes` |
+
+## Phased delivery (recommended)
+
+### Phase A — Local durability (rocks or bee, no swarm yet)
+
+1. Add `hyperdb`, `hyperschema`, `corestore` deps
+2. `scripts/build-db.js` + `spec/`
+3. Persist alert configs, peer policy, warm downsample into HyperDB
+4. REST/RPC history falls back to HyperDB after memory miss
+5. Keep REST localhost semantics
+
+### Phase B — Link & replicate
+
+1. Hyperswarm alongside HyperDHT RPC (or reuse connections carefully — often **separate swarm for store.replicate**)
+2. `linkPeer` / `unlinkPeer` RPCs write `@peardata/peer-link`
+3. Desktop can seed/cache agent DB by key for offline scrubbing
+4. Document `pd1.` invite vs **db discovery key** (two layers)
+
+### Phase C — Parent fleet
+
+1. Parent process pulls N child DB keys
+2. Composite REST `/api/v3/nodes` + scoped `/api/v3/data`
+3. Optional Autobase for parent HA
+
+### Phase D — Polish
+
+1. Encryption at rest (`encryptionKey` on cores / autobee)
+2. Blind-peer seeding for always-on warm history
+3. Grafana: already have REST Prometheus export; optionally expose hypercore-stats
+
+## Concrete file plan (when implementing)

+| `autobee` | Experimental multiwriter bee alternative |
+
+## Decision summary
+
+1. **Yes — incorporate HyperDB** for metadata + warm history + linked-node sync.
+2. **Keep memory + RPC pushes** for live 1s Netdata feel.
+3. **Sync linked nodes via Corestore replication on Hyperswarm**, not by streaming every sample over RPC.
+4. **Use Autobase+HyperDB** when you need multi-writer parents / HA — same pattern as Holepunch’s own workshops.
+5. **Treat discovery keys as sensitive** — link only invited peers; RPC AuthZ remains authoritative for mutations.

+# Tech choices
+
+Recommendations for collection, streaming, visualization, and reusable libraries.
+
+## Transport & identity
+
+| Choice | Why |
+|--------|-----|
+| **HyperDHT** | Same peer identity + hole-punching model as PearDock |
+| **protomux-rpc** | Multiplexed request/response + server push events |
+| **compact-encoding JSON** | Fast enough for control + 1s metric batches; shared with template |
+| **Ed25519 seeds** | Agent address = pubkey; admin proof via HMAC from seed |
+
+### Streaming metrics
+
+MVP uses **protomux-rpc `event` pushes** (`push:metrics`) with per-session subscribe + throttle.
+
+If fleet scale demands it later:
+
+1. Dedicated protomux channel with binary packs (Float64 arrays)
+2. Hypercore / Hyperbee for durable streams a parent can replicate
+3. Extract a shared **`pearrpc`** package (session middleware + hot-path helpers) from this template
+
+For MVP, JSON pushes keep the stack simple and debuggable.
+
+## Collection
+
+| Option | Verdict |
+|--------|---------|
+| **Node `os` + `/proc` (chosen)** | Zero native deps, good enough for MVP, low overhead |
+| `node-os-utils` | Convenient but extra dep / less control |
+| Native bindings (netdata collectors, `systeminformation`) | Higher fidelity; consider Phase 2 for Windows depth |
+| Shell out to `vmstat`/`iostat` | Avoid on hot path |
+
+**Linux:** `/proc/meminfo`, `/proc/loadavg`, `/proc/net/dev`, `/proc/diskstats`  
+**macOS/Windows:** `os` fallbacks (CPU%, freemem, loadavg where available); I/O/net rates may be zero until platform collectors land.
+
+Target overhead: single timer, no child processes per tick, ring buffers only.
+
+## Storage
+
+| Tier | Implementation |
+|------|----------------|
+| Now | In-memory ring (`server/services/store.js`) |
+| Next | **HyperDB** + Corestore (+ Hyperswarm replicate) — see [STORAGE-HYPERDB.md](./STORAGE-HYPERDB.md) |
+| HA / multi-writer parents | Autobase with HyperDB view (`extension: false`) |
+| Avoid | SQLite as primary P2P store; copying corestore folders as “backup” |
+
+### HyperDB engines
+
+| Engine | Sync | Use |
+|--------|------|-----|
+| `HyperDB.bee(core, spec)` | P2P via Hypercore | Agent meta + warm history + linked peers |
+| `HyperDB.rocks(path, spec)` | Local only | Fast local index / desktop cache (`pear-hyperdb` style) |
+
+## Visualization (desktop)
+
+| Option | Verdict |

+| **Canvas sparklines (chosen MVP)** | No extra deps inside Pear; snappy for 1s updates |
+| **uPlot** | Best next step for Netdata-like interactive charts (tiny, fast) |
+| Chart.js / ECharts | Heavier; fine for secondary views |
+| Grafana via REST | External; use `/api/v3/data` + Prometheus export |
+
+## REST
+
+Built-in Node `http` (no Express) — small attack surface, enough for Netdata-style GET APIs.
+
+## Packaging
+
+| Piece | Approach |
+|-------|----------|
+| Agent | Node 20+ , systemd unit `deploy/peardata.service` |
+| Desktop | Pear (`pear-electron` + `pear-bridge`) |
+| Invites | `pd1.` tokens (PearDock-style) |
+| Installer | Phase 1 one-liner script |
+
+## Reusable library extraction (recommended later)
+
+From this codebase / PearDock patterns:
+
+| Package | Contents |
+|---------|----------|
+| `@pear/rpc-session` or `pearrpc` | PeerSession middleware, ACL, rate limit, audit hooks |
+| `pear-metrics-wire` | Context/chart catalog types + query args |
+| `pear-invite` | `pd1.` encode/decode + capability HMAC |
+
+Keep MIT-clean relative to AGPL PearDock sources (template already does).
+
+## Integration seams
+
+| Ecosystem | Seam |
+|-----------|------|
+| PearDock | Container chart plugin reading dock RPC |
+| PearVirt | VM CPU/mem contexts |
+| HoneyPeer | Optional agent directory announcements |
+| BareOS | Bare-compatible collector build |
