What is qp-vault?

A knowledge store where every document has a trust tier, every chunk has a SHA3-256 content ID, every mutation is auditable, and the entire vault is Merkle-verifiable. Air-gap native. Post-quantum ready.

Knowledge that can't be verified can't be trusted.

Highlights

• Trust-weighted search: CANONICAL (1.5x), WORKING (1.0x), EPHEMERAL (0.7x), ARCHIVED (0.25x)
• Content-addressed storage: SHA3-256 CID per chunk, Merkle root per vault
• Knowledge lifecycle: DRAFT -> REVIEW -> ACTIVE -> SUPERSEDED -> EXPIRED -> ARCHIVED
• Temporal validity: Point-in-time queries ("What was our policy on March 15?")
• Memory layers: OPERATIONAL, STRATEGIC, COMPLIANCE with per-layer defaults
• Merkle verification: Single resource or full vault, proof export for auditors
• Health scoring: Composite 0-100 (freshness, uniqueness, coherence, connectivity)
• Plugin system: @embedder, @parser, @Policy with air-gap support (drop .py files)
• CLI: vault init, add, search, inspect, verify, health, status
• FastAPI: 15+ REST endpoints via create_vault_router()
• Capsule audit: Optional cryptographic audit trail via qp-capsule
