Module acp 

acp — lattice as an Agent Client Protocol client.

The ACP adapter half of lattice-ai (AG‑5): spawns an AI coding agent (opencode, and later claude-code-acp / gemini) as a stdio subprocess and drives it over JSON-RPC. Architecturally a network peer like lattice-lsp; runs no agent in-process. Gated behind feature = "acp".

Shares the protocol-neutral editor-capability port (lattice-agent) and the transport-neutral AI-log substrate with the MCP adapter in super::mcp. The :ai-log command is NOT here – it is port-owned and lives in the crate-root commands module.

Modules

commands

ACP lifecycle ex-commands: :opencode / :ai-prompt / :ai-stop.

connection

ACP connection adapter over the agent-client-protocol crate.

conversation

Structured conversation model for the ACP agent UI (AU‑1).

conversation_mode

ai-conversation major mode (AU‑2).

error

Error surface for the lattice-ai ACP client.

handle

Editor-thread handle onto the AI supervisor task (AI-1b).

install

ACP transport boot wiring.

permission_mode

ai-permission-mode — the ACP permission menu (PU-B).

providers

Provider launch configs — the crate’s extension point. Adding an agent is a new constructor here, not a new subsystem.

session

ACP session lifecycle: the initialize -> session/new handshake and prompt, as free functions over a Connection (Tasks 6/7 import these paths).

supervisor

The AI supervisor: an idle tokio task owning the provider child process, the ACP Connection, and the active SessionId (AI-1b).

tool_fold

TCF: fold sources for the *ai:opencode* conversation buffer.
