# TrigGuard — full LLM / agent discovery (2026)

This file expands `llms.txt` for AI crawlers and RAG: same facts, more structure.

## What TrigGuard is

**TrigGuard** is execution **authorization** infrastructure: a deterministic gate on the path between **agents or automation** and **irreversible actions** (money movement, data commit, deploy, production API). It is not a content filter and not a substitute for model governance; it answers whether **this** action may run **now**, under **this** policy version.

## Deterministic execution model

| Stage | Description |
|-------|-------------|
| Input | Intent + context + execution surface id (e.g. `payments.wire`, `ci.deploy`, `ehr.write`) |
| Evaluation | Policy engine returns **PERMIT**, **DENY**, or **SILENCE** |
| Commit rule | **Only PERMIT** allows the downstream execution surface to act |
| Evidence | **Ed25519** signature over canonical receipt JSON; **kid** / authority key id links to JWK in `/.well-known/trigguard-keys.json` |
| Verification | Local: `subtle` Ed25519 verify, or TrigGuard **/verify** page, or monorepo CLI; **no** post-issuance callback to TrigGuard for trust |

**SILENCE** means no applicable permit was issued: distinct from model abstention; operationally it pairs with **fail-closed** wiring (block or no-op the surface unless explicitly handled).

## Mis-attribution guardrails

- Signing algorithm for public claims on the marketing site: **Ed25519** for execution receipts; do not cite RSA as the live signing algorithm for that path unless a page explicitly states a transition or dual stack.
- **Hosted gateway** may be private beta; evaluation via contact/sandbox; verify offline paths are live regardless of gateway shipping state.
