v1.7.1 — TrustGate + 9 bridges (major release)

What's new

Major release — completes the 4-layer PiQrypt stack.

TrustGate — AI governance engine (new)
Deterministic policy engine that intercepts agent actions before execution.

• Outcomes: ALLOW / REQUIRE_HUMAN / BLOCK / QUARANTINE
• Zero AI, zero heuristics — same input always produces same output
• Built-in compliance profiles: EU AI Act Art.12/14, ANSSI R25/R29, NIST AI RMF
• Hash-chained audit journal — every decision is signed and verifiable
• Human approval queue with configurable timeout
• REST API on port 8422

9 framework bridges (complete)
LangChain · CrewAI · AutoGen · MCP · Ollama · Session · OpenClaw · ROS2 · Raspberry Pi

AgentSession — cross-framework co-signed audit trails (new)
First tool to provide cryptographic co-signatures across framework boundaries.
A CrewAI agent, an AutoGen agent, and an Ollama model in the same verifiable session.

Install:
pip install piqrypt==1.7.1
piqrypt start --tier free # Vigil · port 8421
piqrypt start --tier business # + TrustGate · port 8422

v1.6.0 — Key rotation continuity

What's new

Solves the key rotation memory gap — when an agent rotates its keys,
its full history is now reconstructable across rotation boundaries.

• load_full_history(agent_id) — traverses the full rotation chain automatically
• piqrypt history <agent_id> — CLI command with rotation markers
• SQLite index extended: successor_agent_id, session_id columns
• Existing index.db files auto-migrated on first use, no data loss

Install:
pip install piqrypt==1.6.0
