## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Paperclip Runner gives native runs a durable and governed execution path. > - The current native path runs on the control-plane host. > - Remote environments need an authenticated execution-target contract. > - The contract must not change direct adapters or enable new runtimes by default. > - This pull request adds the remote execution substrate and Daytona ingress. > - The benefit is a bounded base for later remote runner transport work. ## Linked Issues or Issue Description Refs #12616. Refs #12352. **Subsystem affected** Cross-cutting. This change touches runner transport, server orchestration, plugin contracts, and shared settings. **Problem or motivation** Native execution cannot resolve an authenticated runner ingress through a remote environment. The server also lacks one provider-neutral contract for remote execution targets. **Proposed solution** Add a default-off runner preview ingress capability. Add transport-neutral runner connectivity. Add remote execution target and lifecycle handling. Add a Daytona ingress implementation with redacted credentials. **Alternatives considered** A provider-specific server path would duplicate orchestration and authorization. A public endpoint without an environment contract would weaken the trust boundary. **Roadmap alignment** This work supports the Cloud and Sandbox agents milestone. It also supports self-healing runs and governed tool access. ## What Changed - Added execution-target traits for local, SSH, and sandbox environments. - Added plugin RPC contracts for runner ingress endpoints. - Added authenticated Daytona preview ingress. - Added transport-neutral PRP outbound connections. - Added remote runner artifact verification and fail-closed provider selection. - Added bounded native session resume, cancellation, and lifecycle recovery. - Preserved Codex-only selection for fresh experimental runner starts. - Preserved all direct adapter execution and finalization paths. - Removed stale Pi provider-pack requirements that security review rejected. - Kept the rollout controls off by default. - Did not change pnpm-lock.yaml, Cargo, database migrations, or GitHub workflows. ## Verification - GitHub Actions will run the repository test, typecheck, build, security, and policy gates. - Focused tests cover ingress validation, redaction, execution targets, remote lifecycle, cancellation, resume, and legacy adapter selection. - Local tests were not run. The requested verification policy uses GitHub Actions for this series. - `git diff --check origin/master...HEAD` passes. - The diff contains 52 files. ## Risks - Remote execution crosses a trust boundary. - The implementation validates target capabilities, artifact digests, provider-pack pins, and connection metadata. - The feature remains default-off. - Fresh native selection remains Codex-only. - Existing direct adapters remain on the legacy path. - This PR does not yet make remote Codex runnable. The next PR adds the Rust WSS and TLS transport. ## Model Used OpenAI Codex with GPT-5.6. The work used high-reasoning agent mode, repository tools, GitHub tools, and parallel code-audit agents. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with Fixes: / Closes / Refs OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal or instance-local Paperclip issues or links - [x] My branch name describes the change and contains no internal Paperclip ticket id - [ ] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented risks above - [ ] All Paperclip CI gates are green - [ ] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge

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.
