Priya RamanandPaperclip b7ec2ff90b fix(adapter-utils): scrub lease timing vars from the wrapper child env
The wrapper deleted only two of its four own session variables from
the spawned child's environment, so the child still inherited the
lease refresh and TTL overrides. T10 asserted an empty leaked-key
list but never set those two variables, so it passed without proving
the scrub. Delete all four variables in both wrapper variants and
extend T10 to set all four through the harness on both variants.

The lease refresh script ran `mv` even when the exclusive create
failed, because the two commands were separate statements with no
`&&`. Join them so the rename runs only after the create succeeds,
and extend T29 to assert that chained shape.

@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.
