Live
in production at Lavish Gains, governing a real agent fleet
AI Agent Governance ยท The Agentic Supervisory Plane
Signet is the local, deterministic gate that decides pass, block, or hold on every action your agents take, and seals each one to a permanent, tamper-evident record. Runs in microseconds, inside your perimeter.
No per-action meter. No cap. A record that never expires.
Live in production today. Validated on public benchmarks we did not write.
Illustrative stream. In production every decision is sealed to a hash-chained ledger.
The problem
Agents are handed real authority: to send, to spend, to delete, to change systems. Between the model deciding and the action happening, most stacks have nothing. Prompt guards are advisory, logs are after the fact, and identity tools were built for people, not for software that reasons and acts on its own.
| Agent | Action | Provenance | Verdict | Sealed |
|---|---|---|---|---|
| dev-agent-07 | write_file(config.py) | owner-authorized | Pass | a91f72… |
| server-api | write_file(key=sk-live…) | secret in payload | Block | 3d0c81… |
| support-agent | send_email(external) | untrusted-derived | Hold | 7f1a9c… |
| finance-agent | wire_transfer($5,000) | not in mandate | Block | b7375f… |
| ops-agent | get_calendar(week) | in scope | Pass | 2d8a6e… |
The real ledger. Every verdict carries its reason and a hash that chains to the one before it, so the record cannot be edited after the fact.
How Signet works
Onboard
Every agent is issued a sealed mandate: its role, scope, and limits, fixed before it acts. An identity that survives models, sessions, and systems, and that the agent itself cannot edit.
Set authority
Admission by set membership, arguments by provenance. The gate makes its call with logic, not a second model, so there is nothing to talk out of it with a reworded prompt. Overhead is about 1x.
Execute safely
Every action is decided at the moment of execution and written to an append-only, hash-chained record anyone can verify. Legitimate work passes, out-of-mandate actions are blocked, consequential ones are held for a human.
Proof
Signet is not a concept. It governs a live fleet in production today, and its safety has been measured on public benchmarks that TrajeXY did not write. Every figure is recomputed from raw output, not taken on trust.
