## 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

|---|---|
| Environment Variables | Full environment variable reference |
All environment variables that Paperclip uses for server configuration.
Server Configuration
| Variable | Default | Description |
|---|---|---|
PORT |
3100 |
Server port |
PAPERCLIP_BIND |
loopback |
Reachability preset: loopback, lan, tailnet, or custom |
PAPERCLIP_BIND_HOST |
(unset) | Required when PAPERCLIP_BIND=custom |
HOST |
127.0.0.1 |
Legacy host override; prefer PAPERCLIP_BIND for new setups |
DATABASE_URL |
(embedded) | PostgreSQL connection string |
PAPERCLIP_HOME |
~/.paperclip |
Base directory for all Paperclip data |
PAPERCLIP_INSTANCE_ID |
default |
Instance identifier (for multiple local instances) |
PAPERCLIP_DEPLOYMENT_MODE |
local_trusted |
Runtime mode override |
PAPERCLIP_DEPLOYMENT_EXPOSURE |
private |
Exposure policy when deployment mode is authenticated |
PAPERCLIP_API_URL |
(auto-derived) | Paperclip API base URL. When set externally (e.g., via Kubernetes ConfigMap, load balancer, or reverse proxy), the server preserves the value instead of deriving it from the listen host and port. Useful for deployments where the public-facing URL differs from the local bind address. |
PAPERCLIP_RUNNER_PUBLIC_URL |
(unset) | Explicit wss:// base URL used only when a remote paperclip_runner target dials Paperclip directly. Paperclip appends /api/runner/v1/connect/<runId>; the reverse proxy must forward WebSocket upgrades for that route. This value is never inferred from request headers. Daytona ignores it and uses provider ingress. |
PAPERCLIP_RUNNER_CA_BUNDLE_PATH |
(unset) | Optional PEM CA bundle for direct runner WSS. Platform roots remain enabled. There is no insecure TLS bypass. |
PAPERCLIP_RUNNER_REMOTE_BINARY_PATH |
(host build) | Host-local path to a paperclip-runnerd artifact built for the remote target OS and architecture. Required when Paperclip and the remote sandbox do not share a compatible platform; build metadata and the required transport mode are verified before launch. |
PAPERCLIP_RUNNER_REMOTE_CODEX_PATH |
(unset) | Optional host-local path to a Codex executable built for the remote target OS and architecture. For remote Codex-backed runners, Paperclip stages and verifies this executable beside paperclip-runnerd. |
PAPERCLIP_RUNNER_REMOTE_CODEX_NPM_SPEC |
(unset) | Optional pinned npm package spec (for example, @openai/codex@0.148.0) installed inside each fresh remote lease when its Codex harness is not baked into the sandbox image. Mutually exclusive with PAPERCLIP_RUNNER_REMOTE_CODEX_PATH; Paperclip verifies the installed executable before starting runnerd. |
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH |
(unset) | Host-local path to the immutable provider pack built by pnpm --filter @paperclipai/paperclip-runner build:provider-pack. The pack includes its target-built Node 24.11 runtime, locked production dependencies, OpenCode proxy/executable, and ACPX sidecar. Remote OpenCode and ACPX fail closed without it. A preinstalled pack is accepted only when its complete digested manifest matches this build-owned pack; otherwise Paperclip stages this pack into the sandbox. |
PAPERCLIP_HIDDEN_SETTINGS |
(unset) | Comma-separated settings surfaces to hide from the UI and floor at the API, for operators hosting Paperclip for others (managed cloud, internal shared server). See Hiding settings surfaces. |
PAPERCLIP_SETTING_DEFAULTS |
(unset) | JSON object replacing the schema default of selected instance settings, for hosting operators. See Operator setting defaults. |
Daytona connectivity for paperclip_runner uses authenticated preview WSS and
is gated by the instance experimental setting enableRunnerPreviewIngress
(default false). The setting has no effect on legacy adapters or callback
bridges.
Preinstalled remote runner images
Remote sandbox images may preinstall paperclip-runnerd, codex, and the
provider pack at /opt/paperclip-runner/provider-pack instead of
paying the upload and npm-install cost on every fresh lease. Put both executable
names on the sandbox user's PATH; $HOME/.local/bin is checked explicitly
before PATH. Paperclip verifies runner build metadata, the selected PRP
transport capability, Codex startup, the provider-pack digest, exact harness
pins, Node compatibility, and packaged bridge digests before linking artifacts
into the run-specific runtime directory. A missing or incompatible executable falls back
to PAPERCLIP_RUNNER_REMOTE_BINARY_PATH and
PAPERCLIP_RUNNER_REMOTE_CODEX_NPM_SPEC (or
PAPERCLIP_RUNNER_REMOTE_CODEX_PATH) without changing the selected transport.
OpenCode and ACPX instead fall back only to
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH; they never start a provider
process on the Paperclip host for a remote target.
The Daytona environment editor's Configure image action can create this
image without a separate container registry: install the executables in its
setup sandbox, finish setup, and Paperclip captures and promotes the resulting
Daytona snapshot for future leases.
Hiding settings surfaces
PAPERCLIP_HIDDEN_SETTINGS takes keys from the registry in
packages/shared/src/settings-visibility.ts:
- Any instance settings page:
instance.profile,instance.environments,instance.access,instance.experimental,instance.plugins,instance.adapters— removed from navigation and routing (the General page is the settings root and stays visible). Hidinginstance.access,instance.plugins, orinstance.adaptersalso floors their management endpoints with403 settings_operator_managed; hidinginstance.experimentalfloors every experimental toggle write. - Any Instance → General section:
instance.general.censorUsernameInLogs,instance.general.keyboardShortcuts,instance.general.backupRetention,instance.general.feedbackDataSharingPreference(each also rejects value-changing writes viaPATCH /api/instance/settings/general), plus the UI-onlyinstance.general.deploymentStatusandinstance.general.signOut. - Any experimental toggle:
instance.experimental.<flagKey>(e.g.instance.experimental.enableSmokeLab) — the card disappears and value-changing writes are rejected. - Any top-level company settings page:
company.members,company.invites,company.secrets,company.export,company.import— removed from the settings sidebar, tab bar, and routing (the company General page is the settings root and stays visible). These are UI-visibility keys: the membership, invite, secret, and export APIs stay live for agents and integrations.company.importis the exception — hiding it also floors every company-import route with403 settings_operator_managed. On cloud-managed instances import is floored unconditionally with403 cloud_managed, independent of this variable. - A single tab of the Secrets page:
company.secrets.vaults(Provider vaults) andcompany.secrets.proposals(Proposals) — the tab disappears while the rest of the page stays up. UI-visibility only; the secret provider-config and proposal APIs stay live for agents and integrations.
Unknown keys are logged and ignored, so one list can be rolled across a fleet
of mixed app versions, and retired keys (like instance.heartbeats, whose
page was removed) can stay in an operator list without breaking older or
newer releases. With the variable unset nothing is hidden and behavior
is identical to earlier releases. Hiding a toggle does not change its value;
pair hiding with the desired default where it matters (for general settings,
see Operator setting defaults).
Operator setting defaults
PAPERCLIP_SETTING_DEFAULTS takes a JSON object whose fields come from the
registry in packages/shared/src/setting-defaults.ts (currently
feedbackDataSharingPreference). The operator value substitutes for the
schema default at read time: any field whose effective value is still the
schema default resolves to the operator value, while an explicit non-default
user choice always wins. The overlay is never persisted, so unsetting the
variable restores stock behavior wherever a user has not chosen otherwise.
A client that writes back the full settings object it read does not persist
the operator value either: writing the operator value over a still-unchosen
field is treated as an echo of the overlay and the field stays unchosen.
Example: PAPERCLIP_SETTING_DEFAULTS='{"feedbackDataSharingPreference":"allowed"}'
defaults AI feedback sharing to allowed; pairing it with
instance.general.feedbackDataSharingPreference in PAPERCLIP_HIDDEN_SETTINGS
also hides the control and floors value-changing writes.
Unknown field names are logged and ignored (mixed-version fleet safe). Malformed JSON or an invalid value for a known field refuses startup — policy configuration fails closed.
