# Finite ACP contract

Part of the [Jig standard library](https://jig.md/contracts/index.md). With a `contracts` parent directory,
copy the installed agreement and its license using
`jig import-contract jig:finite-acp contracts/finite-acp`.

Finite ACP lets ordinary Flow code conduct one native Agent task without
receiving credentials or unrestricted process access. The Flow owns the
conversation and checks its answer. Jig independently enforces the approved
client, finite dispatch policy, lifetime and cleanup.

`https://jig.md/contracts/finite-acp` names an interface, not a permission or
discovery service. A package includes its
[invocation descriptor](https://jig.md/contracts/finite-acp/contract.json) and
descriptor-relative [request](https://jig.md/contracts/finite-acp/requests.json)
and [response](https://jig.md/contracts/finite-acp/responses.json) agreements.
Resolution matches that complete identity offline.

- [Finite ACP specification](https://jig.md/spec/finite-acp.md): grant, framing, authority,
  failure and settlement.
- [Choose an Agent](https://jig.md/guide/agents.md): use a replaceable implementation.
- [Retained native state](https://jig.md/spec/finite-acp.md#retained-native-state): explicit
  retention and restoration under separate reviewed authority. This source
  candidate requires matching artifacts and installed-client qualification.

Channel receipt does not prove a prompt ran, and a completed prompt does not
prove process cleanup. The resource returns actual termination evidence;
the Agent Flow separately returns the checked application result.
When retention was requested, only clean native exit, validated bounded
collection, fencing, cleanup and atomic commit can produce a retained reference
in the final output. A forced close reports unavailable retention. Restoration
claims that reference once under current authorization and never silently
starts a fresh conversation.
