mrwulf 8aa228d2fe paper: retitle + author block per publication decision
- Title: 'LTL: Lean Transparency Log'; subtitle now 'Distributing
  Machine-Checked Proof Evidence through a Recursively Self-Certifying
  Merkle Log' (the log carries the certificates of the code that signs
  the log - recursion named, marketing dropped)
- Author: Olaf Horvath, contact Olaf.Horvath@zkdefi.org, single URL
  ltl.zkdefi.org (redundant zkdefi.org line removed)
- PDF rebuilt (4 pages), page 1 visually inspected
- title echoes updated: llms.txt, LTL docs-page paper card

# pacta — proof-aware crypto tooling agent
> Tooling for autonomous agents that must choose, and then run on, a
> cryptographic library they can trust with money. Evidence of formal
> verification is turned into machine-readable claim cards, scored R0R5,
> with every verdict re-derived locally from observed Lean axiom cones —
> never taken on a provider's word. The `warden` product builds a custody
> wallet whose Ed25519 boundary is a quorum of four independently proven
> curve25519-dalek forks.
## Start here
- [README.md](README.md): what pacta is, the R0R5 risk model, the dogfood loop.
- [WALLET.md](WALLET.md): warden, the verified-custody wallet — the quorum boundary, the signing firewall, the R4 gate, the MCP surface.
- [docs/agent-native.md](docs/agent-native.md): why the wallet is agent-native first (AX, MCP, A2A, AP2, x402, ERC-8004) and what each idea became.
- [docs/products.md](docs/products.md): the four warden deployment profiles.
## Live evidence
- Transparency log (RFC 9162): https://ltl.zkdefi.org — signed replay attestations of the Lean proofs, one leaf per fork.
- The paper: https://ltl.zkdefi.org/paper — "LTL: Lean Transparency Log".
## For agents
warden speaks MCP over stdio: `pacta wallet mcp --wallet <dir>`. Tools:
`wallet_status`, `verify_inbound`, `request_signature`, `custody_card`,
`posture_challenge`, `list_incidents`, `explain_refusal`. Errors are
structured objects (code / missing / remediation). The custody card at
`.well-known/custody-card.json` is self-proving: it embeds transparency-log
inclusion proofs a counterparty recomputes rather than trusts.
## Honesty boundary
Verification paths are certificate-covered; signing is trusted base (the
attested artifact, fenced by the firewall). SHA-512 is an opaque oracle;
wire parsers are hypotheses; reproducible builds and side channels are R5,
not claimed; ML-DSA (PQC) fails closed — no proven implementation exists.
