+# hyper-p2p-mycelium-pool
+
+Production experimental (wave 4) module: Hyperswarm discovery + Protomux when `topic` is set.
+
+**Category:** Experimental (Wave 4)
+
+**Composes with:** `hyper-p2p-pheromone-trail`, `hyper-p2p-whisper-mesh`, `hyper-p2p-entropy-beacon`
+
+**Protocol:** `mycelium-pool/v1`
+
+## When to use
+
+Multi-peer apps that need experimental (wave 4) over a shared Hyperswarm topic.
+
+## When not to use
+
+Single-process tools with no P2P topic (use local APIs only or skip `ready()`).
+
+## Quick start
+
+```js
+const { HyperP2PMyceliumPool } = require('hyper-p2p-mycelium-pool')
+const topic = process.argv[2] // 64-char hex or string
+const mod = new HyperP2PMyceliumPool({ topic, enableBackgroundTimers: false })
+await mod.ready()   // joins swarm when topic set
+// ... application logic ...
+await mod.close()
+```

+# API: hyper-p2p-mycelium-pool
+
+**Protocol:** `mycelium-pool/v1`
+
+**Export:** `HyperP2PMyceliumPool`
+
+## Overview
+
+Production experimental (wave 4) module: Hyperswarm discovery + Protomux when `topic` is set.
+
+## Constructor
+
+```js
+const mod = new HyperP2PMyceliumPool(opts)
+```
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `topic` | varies | null | topic |
+| `keyPair` | KeyPair | random Ed25519 | keyPair |
+
+## Methods
+
+### `balance(peerId)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `donate(peerId, credits)`
+
+- **Returns:** `value`
+- **Throws:**
+  - `Error: credits must be non-negative`
+
+### `borrow(peerId, n)`
+
+- **Returns:** `value`
+- **Throws:**
+  - `Error: borrow amount must be non-negative`
+
+### `repay(peerId, n)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `mergeBalances(remote)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `toJSON(—)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `ready(—)`
+
+- **Returns:** `Promise`
+- **Throws:** — (none documented in method body)
+
+### `getStats(—)`
+
+- **Returns:** `object`
+- **Throws:** — (none documented in method body)
+
+### `close(—)`
+
+- **Returns:** `Promise<void>`
+- **Throws:** — (none documented in method body)
+
+## Events
+
+| Event | Payload |
+|-------|---------|
+| `borrow` | loan |
+| `closed` | no payload |
+| `donate` | peerId, balance |
+
+## getStats()
+
+Returns `{ ...this._stats }` — typically `ops`, `errors`, and module-specific counters (`created`, `relays`, `open`, `peers`, etc.).
+Library-only modules may include `mode: 'local'`.
+
+## Errors
+
+Stable message substrings: see [`../_shared/ERROR_CODES.md`](../../_shared/ERROR_CODES.md).
+
+## P2P
+
+When `topic` is set, `ready()` joins Hyperswarm and opens Protomux `mycelium-pool/v1`.
+
+## Testing
+
+```bash
+npm install && npm test
+```
+
+Integration: [`../../real_tests/integration/mycelium-pool-two-node.js`](../../../real_tests/integration/mycelium-pool-two-node.js)

+
+## State model
+
+- In-memory `Map` / `Set` structures for hot path
+- Optional Hyperbee/Hypercore persistence when `storageDir` or `memoryOnly` is configured
+- `close()` tears down swarm, timers, and clears ephemeral state
+
+## Composition
+
+Composes with: `hyper-p2p-pheromone-trail`, `hyper-p2p-whisper-mesh`, `hyper-p2p-entropy-beacon`.
