+
+HyperP2PTemporalIndex Novel temporal indexing primitive for Bare/Pear P2P. Features: - Multi-level hierarchical time bucketing (year/month/day/hour/minute) for efficient range queries
+
+**Category:** Time & ordering
+
+**Composes with:** `hyper-p2p-vector-clock`, `hyper-p2p-paradox-clock`
+
+**Protocol:** `hyper-p2p-temporal-index/v1`
+
+## When to use
+
+Multi-peer apps that need time & ordering 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 { HyperP2PTemporalIndex } = require('hyper-p2p-temporal-index')
+const topic = process.argv[2] // 64-char hex or string
+const mod = new HyperP2PTemporalIndex({ topic, enableBackgroundTimers: false })
+await mod.ready()   // joins swarm when topic set
+// ... application logic ...
+await mod.close()
+```

+# API: hyper-p2p-temporal-index
+
+**Protocol:** `hyper-p2p-temporal-index/v1`
+
+**Export:** `HyperP2PTemporalIndex`
+
+## Overview
+
+HyperP2PTemporalIndex Novel temporal indexing primitive for Bare/Pear P2P. Features: - Multi-level hierarchical time bucketing (year/month/day/hour/minute) for efficient range queries
+
+## Constructor
+
+```js
+const mod = new HyperP2PTemporalIndex(opts)
+```
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `topic` | `string` | `Buffer` | `null` | Hyperswarm topic; required for P2P `ready()` |
+| `keyPair` | KeyPair | random | Ed25519 key pair |
+
+## Methods
+
+### `insertEvent(data, options = {})`
+
+- **Returns:** `Promise`
+- **Throws:** — (none documented in method body)
+
+### `queryRange(startTime, endTime, options = {})`
+
+- **Returns:** `Promise`
+- **Throws:** — (none documented in method body)
+
+### `queryNearest(targetTime, options = {})`
+
+- **Returns:** `Promise`
+- **Throws:** — (none documented in method body)
+
+### `pruneExpired(force = false)`
+
+- **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)
+
+### `getMetrics(—)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `deriveTopic(timeBucket = null)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+### `setVectorClock(vc)`
+
+- **Returns:** `value`
+- **Throws:** — (none documented in method body)
+
+## Events
+
+| Event | Payload |
+|-------|---------|
+| `close` | no payload |
+| `error` | err |
+| `event` | type |
+| `insert` | event |
+| `prune` | count |
+| `query` | type, count |
+
+## 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 `hyper-p2p-temporal-index/v1`.
+
+## Testing
+
+```bash
+npm install && npm test
+```
+
+Integration: [`../../real_tests/integration/temporal-index-two-node.js`](../../../real_tests/integration/temporal-index-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

Provides efficient time-based indexing, causal event ordering via vector clocks integration, range queries, expiration/TTL, nearest-time lookups, Hyperbee persistence, and Hyperswarm topic-based replication. Enables building decentralized logs, audit trails, metrics, history replay, and time-aware reactive systems. First reusable dedicated temporal index module in the Holepunch/Bare ecosystem — never-before-seen primitive combining temporal queries with P2P causality.",
