Dotta 0a422fda52 feat(runner): add remote execution substrate (#12638)
## 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.

Nicky LeachandPaperclip b6854e61c7 refactor(adapter-utils): rename EffectiveSandboxCapabilities to EffectiveExecutionCapabilities (#12119)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The adapter utilities package defines shared types for agent
execution targets
> - The type name EffectiveSandboxCapabilities describes only one
transport
> - All execution target drivers return the same resolved capability
snapshot
> - This pull request gives the snapshot a general name and keeps the
old type as a deprecated alias
> - The benefit is clearer public vocabulary with source compatibility
for current consumers

## Linked Issues or Issue Description

**What existing behavior does this improve?**

The exported capability snapshot type uses the name
`EffectiveSandboxCapabilities`, although local, SSH, sandbox, and plugin
drivers return it.

**Subsystem affected**

The change affects `packages/adapter-utils` and its server consumers.

**Current behavior**

The public type name points to the sandbox transport. The private parser
also uses the sandbox-only name.

**Proposed behavior**

Use `EffectiveExecutionCapabilities` for the public type and
`parseEffectiveExecutionCapabilities` for the private parser. Keep a
deprecated alias for the old public type.

**Reason and benefit**

The new name matches the established execution-target vocabulary. The
alias keeps existing type imports working during the migration.

**Breaking changes**

None. The runtime field, capability flags, parsed shape, and package
versions do not change.

**Additional context**

GitHub search found no duplicate or related open issue or pull request.

## What Changed

- Rename the exported interface to `EffectiveExecutionCapabilities`.
- Keep `EffectiveSandboxCapabilities` as a deprecated type alias.
- Rename the private parser and update its call site and references.
- Add a type-level test for the deprecated alias.

## Verification

- `npx tsc --noEmit -p packages/adapter-utils`
- `npx vitest run
packages/adapter-utils/src/execution-target-sandbox.test.ts`
- `npx vitest run
server/src/__tests__/environment-execution-target-capabilities.test.ts
server/src/__tests__/environment-execution-target-duplex.test.ts`
- The local checks passed with 133 adapter-utils tests and 31 server
tests.
- Reviewers can confirm that the runtime field and capability flags stay
unchanged.

## Risks

Low risk. The alias protects existing type imports. The change does not
alter runtime behavior or serialized data.

## Model Used

OpenAI Codex, GPT-5, tool use and code execution. The runtime does not
expose the context window size.

Nicky LeachandPaperclip a14e51d592 refactor(environment): classify environment capabilities from static driver definitions (#12045)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Environment runtime drivers provide workspace, lease, and custom
image behavior
> - Runtime code used driver identity checks and several
capability-specific members
> - These checks spread capability rules across the runtime and made new
drivers harder to verify
> - This pull request adds one general capability classifier and one
static driver support table
> - The benefit is one fail-closed capability model that keeps current
behavior and supports future drivers

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Environment runtime capability checks for workspace realization, custom
images, lease capabilities, and duplex authorization.

**Subsystem affected**

Cross-cutting (multiple of the above)

**Current behavior**

The runtime selects several capability paths from driver identity and
separate capability members. Custom image gates also trust provider
declarations without checking every matching live worker method.

**Proposed behavior**

The runtime uses one general capability classifier and one static
support table. Custom image gates require both the provider declaration
and every matching live worker method. The public capability names
remain unchanged.

**Reason and benefit**

The change keeps capability rules in one place. It removes identity
conditions from runtime consumers and makes unsupported drivers fail
closed.

**Breaking changes**

None. The public names sandboxCapabilities, sandboxProviders, and
EffectiveSandboxCapabilities remain available.

## What Changed

- Add classifyEnvironmentCapabilities and static support definitions for
all four driver families.
- Add resolveCapabilities to every environment runtime driver.
- Move driver traits into environment-driver-traits.ts and migrate
runtime consumers.
- Require provider declarations and matching live worker methods for all
custom image gates.
- Migrate duplex authorization to the general resolver and remove the
dead sandbox-only member.
- Delete the unused resolveEffectiveSandboxCapabilities wrapper and
update its test.

## Verification

- pnpm --filter @paperclipai/server typecheck
- pnpm exec vitest run
server/src/__tests__/environment-capability-contract.test.ts
server/src/__tests__/environment-runtime.test.ts — 92 tests pass
- pnpm exec vitest run
server/src/__tests__/environment-driver-traits.test.ts
server/src/__tests__/general-capability-classifier.test.ts — 12 tests
pass
- pnpm exec vitest run
server/src/__tests__/environment-custom-images-service.test.ts
server/src/__tests__/environment-execution-target-capabilities.test.ts
server/src/__tests__/environment-execution-target-duplex.test.ts
server/src/__tests__/environment-execution-target-duplex-kill-switch.test.ts
— 66 tests pass

## Risks

The main risk is a capability gate that denies a valid driver or permits
an invalid driver. The static support matrix, live worker method checks,
and regression tests reduce this risk. No database, public API, or
published type name changes.

## Model Used

OpenAI Codex, GPT-5, with tool use and code execution. The deployment
does not provide a separate context-window value.

Nicky LeachandPaperclip 8161244284 feat(sandbox): add opt-in duplex command-stream foundation (capability, protocol, bounded host route, frame codec) (#11738)
## Thinking Path

> - Paperclip provides a control plane for companies that run AI agents.
> - Sandboxed agents need a safe execution path for persistent command
streams.
> - The existing callback transport does not provide a bounded, generic
duplex route.
> - The host must control capability access, route identity, protocol
limits, and close behavior.
> - This pull request adds an opt-in duplex command-stream foundation
across the sandbox layers.
> - The feature stays inert because no current provider declares the
capability.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting (multiple of the above)

**Problem or motivation**

Sandbox command execution needs a persistent host-to-sandbox stream. The
current callback bridge uses a file transport and does not provide this
generic route.

**Proposed solution**

Add a fail-closed provider capability, generic worker protocol messages,
a host-owned bounded route, cross-layer service mediation, and a
versioned newline-delimited frame codec.

**Alternatives considered**

Keep the file transport and add feature-specific commands. This does not
provide one reusable duplex contract or host-owned route bounds.

**Roadmap alignment**

This work supports the completed Cloud / Sandbox agents roadmap area and
the safe autonomy goal in the product definition.

**Additional context**

The change passed a two-stage security review. The final code review
verdict was approve after fixes for active-stream bounds and
service-layer capability mediation.

## What Changed

- Add the opt-in `duplexCommandStream` provider capability with
fail-closed narrowing.
- Add duplex open, write, stop, and close requests and data and exit
notifications to the plugin worker protocol.
- Add a host-owned route with bounds for chunk size, cumulative bytes,
lifetime, protocol errors, pending requests, and pre-bind buffering.
- Add close acknowledgement handling with worker retirement when the
close remains unconfirmed.
- Wire `openDuplexChannel` through the execution target, runtime
service, and plugin worker.
- Add a versioned frame codec with shared wire-compatibility vectors and
split UTF-8 handling.

## Verification

- `server/src/__tests__/plugin-worker-manager-duplex.test.ts` passes 18
tests.
- `server/src/__tests__/environment-execution-target-duplex.test.ts`
passes 11 tests.
- `packages/adapter-utils/src/duplex-frame-codec.test.ts` passes 38
tests.
- `server/src/__tests__/sandbox-capability-contract.test.ts` passes 15
tests.
- Setup-token pseudo-terminal regression tests pass 47 tests.
- Server TypeScript check passes.
- Continuous integration will run the full required test, typecheck,
build, and policy checks.

## Risks

- Providers that opt into the capability must implement the complete
worker protocol.
- Route limit defaults can close a stream when a workload exceeds the
configured bounds.
- The capability remains disabled for current providers, so current
production behavior does not change.

## Model Used

OpenAI GPT-5 (`gpt-5`), with tool use and code execution. The model
reviewed and prepared this pull request from the supplied implementation
and verification record.

Nicky LeachandPaperclip 233be4b36c feat: parallelize sandbox file-sync behind a provider opt-in capability (#11736)
## Thinking Path

> - Paperclip runs AI agents through local and remote execution
adapters.
> - Sandbox providers move workspace and asset files before and after
agent runs.
> - Serial file transfers delay startup and teardown when several
operations do not depend on each other.
> - Providers need an opt-in contract so existing providers keep their
serial behavior.
> - This pull request adds a bounded scheduler and routes inbound and
outbound sync operations through it.
> - The benefit is shorter sandbox setup and teardown with stable
errors, clear telemetry, and a safe opt-in path.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting (multiple of the above): packages/shared,
packages/adapter-utils, packages/plugins, and server.

**Problem or motivation**

Sandbox sync processes the workspace, assets, and referenced projects in
series. This adds avoidable wait time to agent startup and teardown.

**Proposed solution**

Add a fail-closed provider capability named concurrentSyncOperations.
Use a bounded scheduler with a limit of four operations. Preserve
operation order for error reporting. Keep non-opted-in providers on the
serial path.

**Alternatives considered**

Increase the serial transfer speed or add provider-specific schedulers.
Those options do not provide one shared contract or stable behavior
across providers.

**Roadmap alignment**

ROADMAP.md lists cloud and sandbox agents as a product area. This change
improves sandbox execution without changing the control-plane contract.

**Additional context**

The Daytona provider opts in. Board trials on this commit showed overlap
for inbound sync and outbound restore, with no referenced-project
staging failures.

## What Changed

- Add the concurrentSyncOperations sandbox capability and fail-closed
parsing.
- Add a bounded settle-all scheduler with stable input-order errors.
- Parallelize inbound workspace, asset, and referenced-project sync
operations when the provider opts in.
- Parallelize outbound workspace and asset restore operations when the
provider opts in.
- Surface referenced-project failure text in run logs and server
telemetry.
- Add Daytona sync spans and the capability declaration.
- Preserve in-flight upload scratch tarballs during workspace wipe.
- Add unit and regression tests for the scheduler, coordinators,
provider behavior, telemetry, and wipe race.

## Verification

- Run the adapter-utils and server type checks.
- Run the targeted adapter-utils, server, and Daytona test suites.
- Run the full automated sweep.
- Review six cold Daytona trials, with three serial and three parallel
runs.
- Confirm that parallel trials show inbound overlap and outbound restore
overlap.
- Confirm that providers without the capability keep serial behavior.

## Risks

- Providers must opt in only when their file operations can run safely
at the same time.
- A provider that declares the capability incorrectly can expose
transfer races.
- The scheduler keeps a limit of four to bound resource use.
- Providers without the capability keep the prior serial behavior.

## Model Used

OpenAI GPT-5 in the Codex runtime. The model used tool calls, code
inspection, and GitHub workflow support. The model did not author the
implementation commits.

Nicky LeachandPaperclip 3061ce6901 feat(sandbox): stream session output by capability, drop three operator flags (#11557)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandboxed agents use provider capabilities to select safe execution
paths
> - Session output still depends on three operator flags that duplicate
capability data
> - Duplicate flags can drift from the verified sandbox capability
snapshot
> - This pull request makes the capability snapshot the only streaming
decision and removes the obsolete flags
> - The benefit is default streaming with a poll fallback when a
capability or stream fails

## Linked Issues or Issue Description

**What existing behavior does this improve?**

ACP sandbox session-output streaming and sandbox execution
configuration.

**Subsystem affected**

Cross-cutting (multiple of the above): server/, packages/shared/,
packages/adapter-utils/, and packages/plugins/.

**Current behavior**

Session-output streaming requires operator flags in the server and
Daytona plugin configuration. Saved configurations can retain a removed
key.

**Proposed behavior**

The verified capability snapshot selects streaming. The Daytona plugin
uses persistent sessions by default, keeps bypass commands one-shot, and
falls back from the log stream to polling. Removed configuration keys
become inert.

**Reason and benefit**

One capability source prevents configuration drift. The fallback keeps
output available when capability resolution or log streaming fails.

**Breaking changes**

The three operator flags no longer control session-output streaming.
Existing saved keys load but have no effect.

## What Changed

- Remove `useSessions` and `useLogStream` from the Daytona plugin
configuration and manifest.
- Remove `streamAgentSessionOutput` from server configuration, shared
types, and execution-target plumbing.
- Select streaming from `persistentProcessSessions` and
`independentControlCommands`.
- Keep poll fallback on capability resolution failure and stream
failure.
- Strip removed keys from strict fake-sandbox and catchall plugin
configuration.
- Update the sandbox capability documentation and focused tests.

## Verification

- `tsc --noEmit` passed in `packages/shared`, `packages/adapter-utils`,
`server`, and the Daytona plugin.
- Daytona `plugin.test.ts` passed 139 tests.
- Server capability, configuration, route, and runtime suites passed 160
tests.
- `packages/adapter-utils` `execution-target-sandbox.test.ts` passed 44
tests.
- The capability matrix covers stream, poll, and resolution-failure
paths.
- Removed-key tests cover strict fake-sandbox and catchall plugin
schemas.

## Risks

- A capability snapshot that lacks either required session capability
uses polling.
- A log stream failure uses polling and can increase request count.
- Existing removed configuration keys no longer change behavior.
- The isolated-worktree Daytona Vitest run has a pre-existing missing
`packages/adapters/droid-local` reference. CI and standard checkouts use
the committed configuration.

## Model Used

OpenAI Codex, GPT-5, tool use and code review assistance. The exact
runtime context window is managed by the Codex platform.

Nicky LeachandPaperclip e71ce9a9d3 feat: sandbox provider capability contract with fail-closed effective resolution (#11463)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Paperclip runs work through adapters and sandbox providers
> - Providers need a clear contract so the server can use only verified
capabilities
> - A declared capability must not grant a method that the live worker
did not verify
> - This pull request adds manifest declarations and fail-closed
effective capability resolution
> - The benefit is safe provider reuse across execution targets and run
lifecycles

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting (multiple of the above)

**Problem or motivation**

Sandbox providers expose different runtime methods. The server needs one
safe capability contract that accounts for provider declarations, worker
verification, and narrowing configuration.

**Proposed solution**

Add strict manifest validation for five sandbox capabilities. Resolve
effective capabilities as the subset of verified, declared, and narrowed
values. Store the result as a frozen execution-target snapshot.

**Alternatives considered**

Trusting the manifest alone could grant methods that the worker does not
support. Trusting only a fixed built-in list would reject valid
third-party providers. The intersection rule keeps the verified runtime
ceiling and supports both provider types.

**Roadmap alignment**

This change supports the ACP run lifecycle track and the sandbox
provider contract work in the current roadmap.

**Additional context**

The legacy `supportsReusableLeases` field remains supported. The nested
capability validator rejects unknown keys. Missing or unavailable
verification resolves all capabilities to `false`.

## What Changed

- Add strict `sandboxCapabilities` manifest validation with legacy
reusable-lease compatibility.
- Carry declarations through the ready-driver projection.
- Add fail-closed effective resolution from verified, declared, and
narrowed capabilities.
- Add narrowing for provider configuration, Kubernetes Job leases, and
Daytona sessions.
- Add a frozen read-only capability snapshot to execution targets.
- Add focused tests and keep existing characterization baselines
covered.
- Add and update sandbox provider capability documentation.

## Verification

- `npx vitest run packages/shared/src/validators/plugin.test.ts`
- `npx vitest run
server/src/__tests__/plugin-environment-driver-sandbox-capabilities.test.ts`
- `npx vitest run
server/src/__tests__/sandbox-capability-contract.test.ts`
- `npx vitest run
server/src/__tests__/environment-execution-target-capabilities.test.ts`
- `npx vitest run
packages/adapter-utils/src/acpx-engine/startup-characterization.test.ts
packages/adapter-utils/src/acpx-engine/turn-characterization.test.ts
packages/adapter-utils/src/acpx-engine/settlement-characterization.test.ts
packages/adapter-utils/src/acpx-engine/composed-run-characterization.test.ts`
- Package typechecks for shared, server, and adapter-utils pass.
- Stage-2 security review suites pass with 28 tests.

## Risks

The resolver fails closed when verification is absent or unavailable.
Providers that rely on undeclared capabilities may see narrower behavior
until they expose verified worker methods. The change does not alter the
existing native-sync guard.

## Model Used

OpenAI Codex, GPT-5, exact runtime model ID `gpt-5`, tool use and code
execution. The implementation author used this model to assist with the
change.
