DottaandPaperclip 734c265339 Default new Pi agents to Paperclip Runner (#17142)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Users choose a harness during agent setup.
> - Claude, Codex, and OpenCode already receive their qualified Runner
default.
> - Pi has a qualified native integration but new Pi agents still use
the direct adapter.
> - This change gives new Pi agents the native default on supported
targets.
> - Saved agents keep their runner and compatible settings. Legacy
remains available in Advanced.

## Linked Issues or Issue Description

Refs #17120, #14921, #14922, #14923, #14924, and #14956. Related generic
default work: #15422. This PR is the separate Pi follow-up to the merged
OpenCode change.

**Current behavior**

Choosing Pi for a new agent saves the direct Pi adapter. The native Pi
integration remains behind the generic experimental flag.

**Proposed behavior**

Default new Pi agents to ACPX Pi on macOS ARM64/x64 and GNU/Linux x64
with supported glibc. Keep unsupported targets and explicit Legacy
selections on the direct adapter. Require an explicit provider/model
before test or hire. Permit model-free inactive setup drafts.

**Reason and benefit**

Users choose Pi once and receive its qualified runner. Saved agents
retain their identity and settings. Conversions reject unsupported
legacy thinking and launch settings instead of dropping them.

## What Changed

- Add Pi to the shared platform/default contract and server creation
selection.
- Admit native Pi without the generic experimental flag.
- Preserve provider models, credentials, workspace settings, exact
thinking, and saved native policies.
- Add Pi runner controls, branding, setup resume, onboarding, built-in
configuration, and import handling.
- Add managed Pi OpenRouter routing and matching native provider API-key
accounts. Keep subscription and custom gateway exclusions. Clear
alternate credentials and reject custom Pi provider overrides.
- Keep Pi draft models empty instead of applying Claude's default model.
- Verify setup against the pinned Pi runtime. For native Pi on the
official OpenRouter route, reverify the API key live without requiring a
global Legacy Pi CLI.
- Match Pi’s bounded controller close window to its native snapshot
cleanup and lifetime verification, preserving explicit caller deadlines
and the mandatory drain/suspension proof.
- Bind Pi sidecars to the package that owns the pinned native assets,
including source and vendored server layouts. Other providers retain
their existing package authority.
- Keep protocol-owned finish/block tools out of the ACPX forwarded
catalog. The trusted bridge installs these tools itself; the complete
Rust authorization catalog and terminal receipt ledger remain intact.
This fixes actual Pi session startup and applies to other ACPX
consumers.
- Advance Copilot’s shared-source attestation to v58 because it pins the
shared files touched by Pi. Preserve immutable v57 bytes and historical
decoding; Pi’s own release identity is unchanged.
- Add regression coverage and update the paired maps and developer
documentation.

## Verification

- Passed: full repository typecheck and full production build on final
head 656d304783, including the generated attestation repair.
- Passed: focused shared/server/UI suites covering default selection,
platform fallback, conversion preservation, inactive drafts, managed
account compatibility, credential isolation, OpenRouter routing/model
IDs, exact thinking controls, and saved-account selection. Relevant
batches include 375 server/conversion tests, 267 account/routing tests,
and 110 UI setup/account tests.
- Passed: 179 attestation, historical-profile, qualified-profile, and
native-execution contract tests after CI identified stale Copilot source
hashes. The identity generator check passes; the only delta after the
passing Pi browser run is this Copilot attestation/history repair.
- Passed: 145 managed-account tests, including actual service
preparation and API-key adoption/rejection for native Pi without the
Legacy CLI; 6 pinned-installation probe tests.
- Red then green: an actual task failed session.open because its
54-operation catalog included the bridge-owned terminal tools. The
regression with those tools failed before the filter; all 399 Rust
library tests pass after it. The full product retry exposed an
additional package-authority mismatch. Four authority tests failed
before that repair; 11 authority checks and 14 installation/asset checks
pass afterward. Direct real Pi session initialization with the corrected
package root and catalog succeeds. No model prompt was sent by that
diagnostic.
- Red then green: real Pi posted Hello from Pi but its controller closed
before native cleanup could finish. The cleanup-budget test failed with
the old default and passes with the bounded Pi window. All 46 selected
suspension, drain, and package-authority tests pass after building their
native fixture.
- Passed: token gates, paired map checks, Rust formatting, and git diff
--check.
- Passed real browser acceptance on macOS ARM64, generic native runner
flag disabled, source a433748a12 (Pi code unchanged afterward): the UI
selects Paperclip Runner by default, retains Pi and the selected
model/account, and verifies the pinned runtime plus live OpenRouter key.
A fresh UI-created task, assigned to the UI-created native Pi agent,
posted exactly `Hello from Pi` and reached Done without retry or
restart. The native run and workspace finalization succeeded; the
response and Done persisted after Reload.
- Evidence: 8 preserved browser attempts, including the final passing
18-step journey with all screenshots. Prior failures remain recorded.
The earlier failed checkpoint run recovered on server restart; that
recovery is separate from the fresh final task’s clean success.
- Preserved browser failures: missing account control/inherited Claude
draft model; incompatible managed-account/model-prefix handling; generic
npm probe for Pi; Legacy CLI hello check; duplicate terminal tools and
wrong provider-package authority at actual native session.open; a real
Hello from Pi comment followed by premature checkpoint cleanup timeout.
Each failure has retained screenshots/logs and a corresponding focused
repair. The fresh final task proves these repairs end to end.
- The exact Runner Vitest shard was also run locally after the
attestation fix: the stale-hash failure is gone; 1,833 tests passed, 10
skipped, and two Codex retained-control settlement scenarios failed with
`native_cleanup_maintenance_unproven` during terminal ACK/suspension
replay. Both scenarios passed in an isolated rerun (2/2), and the same
19-test file passed in the preceding Linux CI run. The precise
full-shard timing cause is not established. These Codex scenarios are
outside the changed Pi paths; the original local failures are retained;
no complete local Runner-shard pass is claimed. The corresponding Runner
shard now passes on the final head in hosted Linux CI. All 60 final-head
check runs are now terminal and clean (55 successful, 1 neutral, 4
skipped), and the legacy Snyk status is successful.
- Local full repository tests were attempted but not completed:
provisioning briefly confused a workspace symlink, then a later run was
stopped before browser-driven repairs. No full local-suite pass is
claimed. Final-head hosted CI is green and fresh Greptile review is 5/5
with all review threads resolved; earlier jobs canceled by runner
shutdown are not counted as a pass.

## Risks

- Pi cleanup has a finite 45-second default window, accounting for the
native 30-second snapshot cleanup and 5-second lifetime fence. Other
providers and explicit caller deadlines retain their prior behavior.
- Pi requires explicit operator setup with `paperclipai runtime setup
pi` on the execution host. This PR does not add automatic downloads.
- Linux ARM64, Windows, musl, and unqualified targets retain Legacy.
- Legacy thinking levels minimal, medium, and xhigh cannot be translated
exactly. Native max thinking, warm lifecycle, or restricted permissions
cannot be dropped during a return to Legacy.
- Copilot’s bound profile advances to v58 with exact current launch
admission; v57 remains decodable for recovery. No historical identity is
rewritten.
- Existing agents and immutable run descriptors are not migrated. Cloud
Pi availability is unchanged.

## Model Used

OpenAI GPT-6 through Codex with reasoning, code editing, command
execution, and browser use. The exact serving model ID and
context-window size are not exposed in this session.

@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.

Sandbox bridge deadlines

Command-managed bridge control operations (queue reads, input delivery, setup, and cleanup) have a host-enforced deadline of at most 30 seconds per shell command. A shorter configured timeout still applies. These operations cannot inherit the agent run's hours-long lifetime or wait forever on a provider that ignores its timeout. Long-lived agent session commands keep their own limits.

A control timeout reports a transport failure. It does not prove that the remote command stopped and does not replay an uncertain write. The process session closes failed input delivery and uses its existing shutdown path; normal execution settlement must still verify termination.

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.
