Priya RamanandPaperclip 223068e2ff fix(sandbox): keep bridge queue-directory setup on the startup step
The paperclip callback bridge reset the active startup-step store for the
whole worker start. That also unparented the awaited queue-directory setup
execs, which are startup work and must keep the `bridge.paperclip` step.

Move the store reset to the long-lived poll loop inside the worker. The
`makeDir` setup now keeps the active step, so its `sandbox.exec` spans stay
parented with the correct `criticalPath` flag. The loop still runs with an
empty store, so each run-time exec span opens unparented.

Add a regression test that reads the active step during setup and during the
first poll, and proves the boundary sits at the loop, not the whole worker.

@paperclipai/adapter-utils

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) to remoteDir before the run starts. Runs with no git remote configured.
  • restoreWorkspaceFromSshExecution({ spec, localDir, remoteDir, ... }) — syncs the remote cwd back into localDir after the run, including any new commits the agent created. Also runs with no git remote configured.

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.
