Summary

Implements OSpipe — a quantum-enhanced personal AI memory system that integrates Screenpipe with the RuVector ecosystem. Replaces Screenpipe's SQLite + FTS5 search with SIMD-accelerated HNSW vector search, adding semantic search, PII safety, frame deduplication, and cross-platform deployment.

What's Included

  • Rust Core Library (examples/OSpipe/) — 30+ source files across 10 modules

    • capture — Frame data structures (OCR, transcription, UI events)
    • storage — HNSW-backed vector store + pluggable embedding trait
    • search — Query router + hybrid search + MMR diversity + attention reranker
    • pipeline — Ingestion pipeline with deduplication + enhanced search orchestrator
    • safety — PII detection and content redaction (CC, SSN, email with whitespace preservation)
    • graph — Knowledge graph with entity extraction (persons, URLs, emails, mentions)
    • learning — Continual learning with EWC + experience replay buffer
    • quantum — Quantum-inspired search diversity (QAOA + Grover amplitude boost)
    • persistence — JSON-file persistence layer
    • server — Axum REST API server with all TypeScript SDK endpoints
    • wasm — wasm-bindgen exports for browser deployment
    • config — Full configuration with HNSW params, quantization tiers, MMR lambda

  • Server Binary (ospipe-server) — Standalone REST API server

    • --port, --data-dir, --help, --version CLI flags
    • Tracing with env-filter logging

  • TypeScript SDK (npm/packages/ospipe/) — @ruvector/ospipe

    • Semantic vector search, knowledge graph, temporal delta queries
    • SSE-based attention-weighted event streaming
    • fetchWithRetry with exponential backoff, timeout, AbortSignal
    • Backward-compatible Screenpipe v1 API
    • 14 exported TypeScript interfaces

  • WASM Package (npm/packages/ospipe-wasm/) — @ruvector/ospipe-wasm

    • 145 KB WASM binary built with wasm-pack
    • Insert, search, filtered search, dedup, safety check, query routing, batch embed

  • ADR (examples/OSpipe/ADR-OSpipe-screenpipe-integration.md) — 1,986 lines

Screenpipe vs OSpipe

Aspect Screenpipe OSpipe
Search Keyword (FTS5) Semantic + Keyword + Graph + Temporal + Hybrid
Indexing B-tree HNSW O(log n) ANN
Reranking None Attention + MMR diversity + Quantum diversity
Latency ~1ms 61μs (HNSW p50)
Relations None Knowledge Graph with entity extraction
PII Basic CC, SSN, email redaction (whitespace-preserving)
Dedup None Cosine similarity gate with sliding window
Browser None WASM (145 KB)
Learning None EWC + experience replay
Quantization None 4-tier age-based (f32 → int8 → product → binary)
REST API Custom Axum server matching SDK endpoints
Persistence SQLite JSON-file + vector store

RuVector Integration (10 crates)

  • ruvector-core — HNSW vector storage + embedding providers
  • ruvector-filter — Metadata filtering
  • ruvector-cluster — Frame deduplication
  • ruvector-delta-core — Change tracking
  • ruvector-router-core — Query classification
  • cognitum-gate-kernel — AI safety gate
  • ruvector-graph — Knowledge graph DB
  • ruvector-attention — Scaled dot-product attention reranking
  • ruvector-gnn — Graph neural nets + EWC continual learning
  • ruqu-algorithms — QAOA quantum-inspired diversity selection

Add four new OSpipe modules integrating RuVector crates:

- graph: KnowledgeGraph wrapping ruvector-graph with heuristic entity
  extraction (URLs, emails, @mentions, capitalized phrases), entity/
  relationship CRUD, and frame entity ingestion
- search/reranker: AttentionReranker using ruvector-attention scaled
  dot-product attention for result re-ranking (0.6*attention + 0.4*cosine)
- learning: SearchLearner with EWC (ruvector-gnn) for continual learning
  without catastrophic forgetting, ReplayBuffer for feedback, and
  EmbeddingQuantizer for age-based vector compression
- quantum: QuantumSearch using ruqu-algorithms QAOA for diversity selection,
  Grover-inspired amplitude boosting, and optimal iteration estimation

All modules use cfg-gated dual implementations (native + WASM stub).
60 tests passing (59 integration + 1 doc-test), native + WASM builds clean.

…, MMR, safety fixes

Implements all remaining OSpipe features from the gap analysis:

High — Core functionality:
- HNSW indexing via ruvector-core with O(log n) ANN search (HnswVectorStore)
- EmbeddingModel trait + RuvectorEmbeddingModel for pluggable embedding backends
- JSON-file persistence layer (PersistenceLayer) for frames and config
- Axum REST API server matching TypeScript SDK endpoints (/search, /graph, /health, /stats, /route)
- Enhanced search pipeline wired into ingestion (router -> rerank -> quantum diversity)

Medium — Correctness:
- WASM/native routing consistency (aligned keyword sets and priority order)
- WASM/native safety consistency (email detection, deny keywords, CC/SSN patterns)
- MMR (Maximal Marginal Relevance) reranker for diversity vs relevance tradeoff
- Delete and update_metadata APIs on VectorStore and HnswVectorStore
- Email redaction preserves surrounding whitespace (tabs, newlines, multi-space)

Lower — Polish:
- TypeScript SDK: fetchWithRetry with exponential backoff, timeout, AbortSignal
- console_error_panic_hook init in WASM module
- WASM test scaffold (tests/wasm.rs)
- Quantization tiers in config (None -> Scalar -> Product -> Binary by age)
- All clippy warnings resolved (0 warnings)

82 tests passing, 1 doc-test passing, 0 clippy warnings.
