Runtime governance, policy enforcement, and cryptographic audit ledger for MCP tool calls

Verifiable, recomputable ℤ/9 vortex framework in ONE package — content-addressing, audit ledger, exact arithmetic, and the honesty toolkit. Facts only.

Siduri Archive domain: Sovereign cold append-only interaction audit ledger and FTS5 search (RFC VX-26-13)

Self-evolving memory for DeepSeek Harness (DSH): earned experiences, diary/fact semantic memory, concern tracking, and an append-only audit ledger.

Spend-aware Codex automation for open source maintainers: policy gates, budget enforcement, an audit ledger, and PR spend reports.

ReZ-TI token/audit ledger for DeepSeek Harness MCP and tool calls.

Immutable audit ledger with cryptographic chaining, Merkle proofs, and distributed sync for the MANYA Intelligence OS.

Threat-response primitives for noy-db — multi-attempt lockout, duress-secret data destruction, duress-secret honeypot decoy. Pure stateful helpers; the caller coordinates keyring + audit-ledger integration. Part of the @noy-db/on-* authentication family.

Cots.ai agent interceptor SDK — configure once, then every governed action is intercepted, evaluated, held for approval if needed, and proven in the audit ledger.

Structured JSON plaintext export for noy-db — decrypts records and emits one JSON document per vault. Gated by `vault.assertCanExport('plaintext', …)` capability; writes an audit-ledger entry on every call. Part of the @noy-db/as-* portable-artefact famil

The estate's append-only audit ledger: the table's shape and walls, erasure, export, readers and a cross-app read handler, with a signer a host builds once inside its trusted base and never exports. Per-app Postgres, a host-supplied vocabulary of closed s

Autonomous memory governance safety layer, proposal staging queue, and audit ledger for AIET

Local web UI for usertrust vaults: filterable audit ledger, live tail, trends, verification.

Consensus Hardening Protocol — Profile B capital gate, canonical JSON, and signed audit ledger for TypeScript

APE — hybrid-native MCP server with an embedded, user-configurable agent: multi-engine orchestration (Genesis + EVE + ADAM + Skein), declarative connectors, task-graph execution, audit ledger, memory. No 5-repo clone required.

MCP server that lets Claude, Cursor, LangGraph, and other agents record AI decisions to a tamper-evident ledger.

The missing buyer-side runtime for x402: fund your AI agent once; it pays any x402 API autonomously inside hard policy rails — budgets, per-call caps, velocity circuit breakers, host allowlists, kill switch, audit ledger.

Single-attachment plaintext export for noy-db — extracts one blob from BlobSet as native MIME bytes. Gated by the RFC #249 `assertCanExport('plaintext', …)` gate; writes an audit-ledger entry on every call. Part of the @noy-db/as-* portable-artefact famil
