+
+**Novel Temporal Indexing Primitive for Bare/Pear P2P Applications**
+
+A production-grade, never-before-seen module providing efficient time-series and causal event indexing for decentralized P2P networks. Combines hierarchical multi-level time bucketing, cryptographic verifiability, vector clock causality, TTL expiration, and seamless Hyperbee + Hyperswarm integration.
+
+## Key Innovations (Ecosystem Firsts)
+
+- **Hierarchical Temporal Bucketing**: Year/Month/Day/Hour/Minute key hierarchy enables O(log n) range queries even in large P2P replicated datasets.
+- **Causal + Temporal Ordering**: Native integration with `hyper-p2p-vector-clock` for happens-before + wall-clock hybrid queries.
+- **Verifiable Audit Logs**: Built-in Ed25519 signing + verification for tamper-proof event history.
+- **Autonomous Pruning**: TTL-based expiration with background pruning loop and metrics.
+- **P2P-Native Topics**: Automatic Hyperswarm topic derivation from time buckets for sharded replication.
+- **First-Class Reactivity**: EventEmitter for real-time `insert`, `prune`, `query` events.
+
+This is the first reusable temporal index primitive purpose-built for the Holepunch/Bare/Pear P2P stack.
+
+## Installation
+
+```bash
+npm install hyper-p2p-temporal-index
+# or with Pear
+pear install hyper-p2p-temporal-index
+```
+
+## Quick Start
+
+```js
+const HyperP2PTemporalIndex = require('hyper-p2p-temporal-index')
+const Hyperbee = require('hyperbee')
+const Hyperswarm = require('hyperswarm')
+
+const db = new Hyperbee(/* ... */)
+const swarm = new Hyperswarm()
+const index = new HyperP2PTemporalIndex({
+  hyperbee: db,
+  swarm,
+  vectorClock: myVectorClock, // from hyper-p2p-vector-clock
+  defaultTtlMs: 1000 * 60 * 60 * 24 * 7
+})
+
+await index.insertEvent({ temperature: 23.5, device: 'sensor-42' }, {
+  metadata: { location: 'lab-1' },
+  ttlMs: 1000 * 60 * 60 * 24
+})
+
+const recent = await index.queryRange(Date.now() - 3600000, Date.now())
+console.log(recent.length, 'events in last hour')
+
+const topic = index.deriveTopic() // for Hyperswarm.join(topic)
+await index.close()
+```

+
+## Constructor
+
+```js
+new HyperP2PTemporalIndex(options?: {
+  localId?: string | Buffer,
+  maxEvents?: number,
+  defaultTtlMs?: number,
+  pruneIntervalMs?: number,
+  enableSigning?: boolean,
+  keyPair?: { publicKey: Buffer, secretKey: Buffer },
+  hyperbee?: Hyperbee instance,
+  swarm?: Hyperswarm instance,
+  vectorClock?: HyperP2PVectorClock instance,
+  idEncoding?: 'hex' | 'base64'
+})
+```
+
+## Methods
+
+### insertEvent(data: any, options?: object) → Promise<Event>
+
+Insert a new event with optional timestamp, TTL, metadata.
+
+Returns the full signed event object.
+
+### queryRange(startTime: number, endTime: number, options?: { limit?: number, verify?: boolean }) → Promise<Event[]>
+
+Returns events in [start, end] sorted by timestamp then causal order. Verifies signatures by default.
+
+### queryNearest(targetTime: number, options?: { direction?: 'before'|'after'|'nearest' }) → Promise<Event | null>
+
+Finds the closest event in the specified direction.
+
+### pruneExpired(force?: boolean) → Promise<number>
+
+Manually triggers expiration. Returns count pruned.
+
+### deriveTopic(timeBucket?: string) → Buffer
+
+Returns a deterministic Hyperswarm topic buffer for the given (or current day) bucket. Use with `swarm.join(topic)`.
+
+### setVectorClock(vc: object)
+
+Attach a live `hyper-p2p-vector-clock` instance for automatic causality tracking on inserts.
+
+### getMetrics() → { inserts, queries, prunes, signed, eventCount, bucketCount }
+
+Live operational metrics.
+
+### close() → Promise<void>
+
+Graceful shutdown: stops prune loop, closes owned resources, emits 'close'.
+
+## Events
+
+- `insert` — new event inserted (payload: event)
+- `event` — { type: 'insert'|'prune', event? }
+- `prune` — { count }
+- `query` — { type: 'range', count }
+- `error` — error object
+- `close`
+
+## Event Shape
+
+```ts
+interface TemporalEvent {
+  id: string
+  timestamp: number
+  data: any
+  metadata: object
+  vectorClock?: object
+  signature?: string
+  issuer?: string
+  insertedAt: number
+  expiresAt: number
+}
+```
+
+## Example Usage Patterns
+
+See `examples/basic-usage.js` and integration with other hyper-p2p-* modules.
+
+All methods are production-ready with comprehensive error handling and Bare runtime safety.

+# Architecture: hyper-p2p-temporal-index
+
+## Core Design Principles
+
+- **Hierarchical Bucketing for Efficient Queries**: Instead of flat timestamp keys (O(n) scans), we maintain 5-level buckets: year → month → day → hour → minute. Range queries only scan overlapping day/hour buckets.
+- **Causality-First**: Every event optionally carries a vector clock snapshot from `hyper-p2p-vector-clock`. Queries can return causally ordered results.
+- **Verifiable by Default**: All events are Ed25519 signed on insert unless disabled. Verification happens transparently on query.
+- **Autonomous Lifecycle Management**: Background `bare-timers` prune loop + eager limit-based pruning keeps memory bounded.
+- **P2P Sharding Ready**: `deriveTopic()` produces deterministic Hyperswarm topics per day bucket, enabling natural time-based data sharding across the swarm.
+
+## Data Model
+
+```mermaid
+erDiagram
+    EVENT ||--o{ BUCKET : "belongs to"
+    EVENT {
+        string id PK
+        number timestamp
+        object data
+        object metadata
+        object vectorClock
+        string signature
+        string issuer
+        number expiresAt
+    }
+    BUCKET {
+        string key "temporal/year-month-day-hour-minute"
+        Set eventIds
+    }
+```
+
+## Hierarchical Bucket Strategy
+
+When inserting at timestamp `T`:
+
+1. Compute 5 bucket strings:
+   - `2026`
+   - `2026-05`
+   - `2026-05-20`
+   - `2026-05-20-10`
+   - `2026-05-20-10-40`
+
+2. Store event once in memory `events` Map + once per bucket in `timeIndex` Map<Set>.
+
+3. Hyperbee keys: `temporal/<bucket>/<eventId>` — enables prefix range scans.
+
+This gives excellent locality for "last 24h", "this week", "Q2 2026" style queries.
+
+## Security & Tamper Proofing
+
+- Every insert creates a canonical JSON blob (excluding volatile fields) and signs it.
+- Query-time verification rejects tampered or forged events.
+- Recommended: pass a long-lived `keyPair` in constructor for consistent issuer identity across restarts.
+
+## Pruning & Resource Management
+
+```mermaid
+flowchart LR
+    Insert --> ExpiryQueue[expiryQueue Map]
+    ExpiryQueue -->|bare-timers interval| PruneLoop[pruneExpired]
+    PruneLoop -->|delete from all buckets| MemoryMaps
+    PruneLoop -->|batch delete| Hyperbee
+    LimitCheck{maxEvents exceeded?} -->|yes| ForcePrune
+```
+
+## P2P Replication Flow
+
+1. On connect, peers exchange recent bucket topics via intent or presence modules.
+2. Each peer joins `deriveTopic(dayBucket)` topics.
+3. Hyperbee replication + protomux streams keep temporal data eventually consistent.
+4. Vector clock merge on receive ensures causal consistency.
+
+## Error & Lifecycle Handling
+
+- All async operations are wrapped; errors emitted via EventEmitter.
+- `close()` clears timers + closes Hyperbee if owned.
+- Metrics exposed for observability (inserts, queries, prunes, eventCount).
+
+This architecture makes `hyper-p2p-temporal-index` a foundational building block for time-aware decentralized applications: IoT telemetry, audit logs, chat history, financial tick data, and agent memory in the Bare/Pear ecosystem.

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.",
