Review feedback on the previous fix: the point of ACPX is to stop maintaining the CLI adapter, so recovering from a codex-acp set_config_option rejection by switching lanes was the wrong shape. ACP-native handling instead: - The codex model is now applied via a `-c model=...` startup config override on the codex-acp command (mirroring ANTHROPIC_MODEL for claude). The override feeds the same config surface as ~/.codex/config.toml, which accepts manual model ids; verified against codex-acp 0.12.0 that session/new then reports the manual id as currentModelId while set_config_option validation rejects unlisted ids on older versions. - session/set_config_option application is now best-effort: a rejected option (e.g. ACP -32602) logs loudly, surfaces in the run's command notes, and the run continues on the agent default instead of dying with acpx_session_config_failed. - The ACP->CLI session-config fallback and its error-code constant are reverted; auto lane falls back to CLI only for startup failures, as before.

Shared utilities for Paperclip adapters: process spawning, environment injection, sandbox/SSH transport, workspace sync, and the round-trip helpers that move code between the local execution-workspace cwd and wherever the agent actually runs.
For the adapter-author guide see
docs/adapters/creating-an-adapter.md
and the in-repo notes at packages/adapters/AUTHORING.md.
No-remote-git contract
The local execution-workspace cwd is the only persistence boundary across runs. No adapter may depend on a git remote for cross-run state.
Adapters that run the agent on a different host should use the SSH round-trip
helpers in src/ssh.ts:
prepareWorkspaceForSshExecution({ spec, localDir, remoteDir })— bundles the local cwd (tracked files, dirty edits, untracked additions, and the git history needed to reconstruct it) toremoteDirbefore the run starts. Runs with nogit remoteconfigured.restoreWorkspaceFromSshExecution({ spec, localDir, remoteDir, ... })— syncs the remote cwd back intolocalDirafter the run, including any new commits the agent created. Also runs with nogit remoteconfigured.
prepareRemoteManagedRuntime in
src/remote-managed-runtime.ts wraps both
calls for adapters that want a per-run remote workspace and an automatic
restoreWorkspace() finally hook.
The invariant is pinned by the no-remote-git contract case in
src/ssh-fixture.test.ts, which asserts that a
remote-only commit propagates to the local worktree through the
prepare → restore round-trip with no git remote configured at any point. Do
not regress that test.
