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.

Apps, Connections, and Integrations

Audience: internal engineers and product contributors working on integrations.

Start here when adding a provider: Connection authoring runbook. It is the canonical agent tutorial from provider research and protocol classification through manifest generation, branding, secrets, deterministic tests, real-account proof, and PR submission.

Runtime authentication: AI Connections.

Long-term memory: Experimental memory connectors.

Provider notes: Google Workspace, Gmail, Asana, Sentry, PostHog, Braintrust, Neon, Superagent, Gauge, Ditto, AgentMail, Telem.AI, iMessage Photon, and Enterpret. Optional credential custody: Vercel Connect.

Post-read action: classify a new integration request, pick the right Paperclip layer to change, and avoid creating a parallel connection framework.

Decision Record

Board decisions from PAP-13211 make the Apps v2 substrate on the PAP-10341 branch canonical:

  • D1: Apps v2 is the substrate. The active model is tool_applications, tool_connections, catalog entries, profiles, policy rules, action requests, gateway sessions, audit events, and runtime slots. Connections v1 is retired as an implementation path.
  • D2: one credential authority per connection, brokered projections. The default is the Paperclip instance vault: durable third-party credentials live in company_secrets as secret refs. A reviewed remote MCP method may instead opt in to Vercel Connect, in which case Vercel is the durable credential authority and Paperclip stores only the connector reference and redacted grant metadata. A connection must never mix those two sources. Adapter config, plugin config, harness credential files, and run environments may receive only brokered or projected credentials.
  • D3: the vocabulary and three-door IA are product law. The default product doors are Apps, Connections, and Review. Protocol and operator-depth concepts live behind Developer or Advanced surfaces.
  • D4: unification lands on PAP-10341. Pages, CircleBack-style harness MCP OAuth, provider gallery work, and plugin-provided integrations converge on this branch instead of spawning new integration substrates.
  • D5: inbound stays thin. External clients that call Paperclip use scoped Paperclip tokens and existing profiles/rules. They do not get a separate permission model.

Canonical Object Model

Use connection as the unifying noun. A connection is four things:

  1. A stored credential reference.
  2. A capability catalog.
  3. A governance layer.
  4. An audit trail.

Everything else is an axis on that object:

Axis Values It answers
Direction outbound, inbound Who is the client?
Transport MCP, native REST/OpenAPI, OAuth app install, webhook How do bytes move?
Auth mode OAuth, API key/PAT, app installation, none What does the secret represent?
Credential owner company, user, run Whose identity acts?
Packaging catalog entry, plugin, skill How does it ship?

MCP is a transport, not a product category. "Install the Discord app", "connect Google Drive", and "add an MCP endpoint" all produce governed connections with different transport/auth values.

Layer Stack

When you are unsure where a change belongs, place it on the narrowest layer that solves the problem:

Layer Owns Examples
Surface user-facing Apps, Connections, Review, Developer/Advanced screens gallery cards, setup wizard, review queue
Governance profiles, bindings, allow/ask-first/block rules, quarantine, audit read-only profile, ask-first write policy
Capability action catalogs, schemas, risk classes, changed-tool review search_issues, create_comment, schema hash
Credential company_secrets, OAuth broker, credential resolver, token broker Slack bot token ref, Google OAuth refresh token ref
Identity actor attribution and token exchange board user, agent run, first-party service identity
Transport how the external system is reached remote HTTP MCP, local stdio, REST/OpenAPI, webhook

The agent should not hold a durable provider credential. It should hold a Paperclip run/session token; the server or broker resolves the connection, checks governance, invokes the provider, and writes audit.

Identity vs. connections

Signing a user in and connecting a resource are different planes with different owners, different token profiles, and different homes. Do not merge them. This section is the public, connections-side statement of the identity model so connector implementers inherit the rule without depending on private identity-service documentation or re-deriving it.

Plane Question Lives where Token profile
P1. Sign-in methods Who are you? paperclip-id (id.paperclip.ing → Account) Minimal-scope provider tokens (openid email profile), used once to authenticate, encrypted at rest, never exported
P2. Connections (Apps) What may your agents touch? Paperclip App instances (tool_connections), acquired via the connect broker for hosted + self-hosted Rich-scope, long-lived resource tokens in the instance's encrypted vault; per-agent grants; risk-tier policy defaults
P3. Login with Paperclip Who may authenticate against us? paperclip-id OIDC provider + DB-backed client registry Our ES256 ID/access tokens issued by us to registered RPs (instances, the broker, future third parties)

Everything in doc/connections/ — the First-30 matrix, the connection authoring runbook, and the connect-broker work — lives on plane P2. It never acquires, stores, or brokers a P1 sign-in token.

The standing rule (D7)

Adopted as a standing rule (decision D7) with the identity-model plan. State it verbatim in any P2 design so the app-store work cannot drift into merging the planes:

Sign-in tokens are never reused as resource tokens; id.paperclip.ing never stores resource tokens; no connections hub on the ID service.

P2 tokens flow broker → instance vault as pass-through only; the id.paperclip.ing Account page therefore must not grow a "Connections" hub. The reasons to hold the planes apart (from the plan §3):

  • Scope discipline. Sign-in wants the narrowest grant; connections want deliberately broad ones. One button that does both is how you grant repo access just to log in.
  • Blast radius. id.paperclip.ing holding every customer's Vercel/Slack/GitHub resource tokens would make it the single juiciest target in the fleet; the broker is intentionally pass-through.
  • Self-hosted symmetry. Instances own their vaults, so self-hosters don't depend on our uptime to use their own connections.
  • Legibility. Sign-in and connections answer different user questions, and every product we benchmarked (Vercel, Railway, GitHub, Google) keeps them on separate pages with separate names.

The explicit Vercel Connect exception does not change D7 or merge P1 and P2. The operator chooses Vercel as the P2 credential authority for an individual connection. id.paperclip.ing is not involved, and neither sign-in tokens nor provider tokens pass through it. The deployment's Vercel access token or workload OIDC identity is bootstrap authority for that external vault, not a provider resource credential.

Naming alignment

Use the surface-correct name for each plane; they intentionally differ:

Surface Plane Name to use
Paperclip App instances P2 "Connections"
id.paperclip.ing Account P1 "Ways to sign in"
id.paperclip.ing admin P3 "OIDC clients" (until the app store productizes it)

Packaging Rule

Default to a catalog entry when an integration can be described as metadata: manifest, auth config, action catalog, resource filters, and policy defaults.

Use a plugin only when the integration needs product code such as custom UI pages, its own tables, workers, migrations, routines, or specialized ingestion. A plugin may bundle catalog entries, but it must not bypass the connection, profile, policy, credential, and audit model.

Use a skill for agent instructions. Skills may use connections; they must not own durable tokens.

Canonical Docs

  • Glossary defines product and internal terms.
  • Identity vs. connections is the public statement of the P1/P2/P3 boundary and the D7 standing rule for connections work.
  • Security threat model harvests the keeper from PAP-2359 and maps it onto Apps v2.
  • First-30 matrix harvests the keeper from PAP-2432 and is the source matrix for connector playbook work.
  • Connecting any remote MCP server is the baseline: how an operator connects a standards-compliant remote MCP endpoint with no Paperclip code change, and how sign-in resolves a client.
  • Connection authoring runbook is the one end-to-end, agent-executable guide for adding a vendor as a catalog entry on Apps v2: research, connection-type selection, OAuth/API-key/generated-URL setup, encrypted credential handling, branding, implementation, browser and live-provider testing, verification, and PR submission.
  • Vercel Connect operator guide documents the optional external credential source, deployment flags, runtime resolution, recovery, and smoke requirements.
  • MCP access governance remains the operator runbook for the current gateway, profile, policy, approval, runtime, and audit APIs.

Migration Notes

Connections v1 contributed useful policy, UX, and rollout thinking, but its implementation branch is no longer the target. When you see old tickets or code using connections, connection_grants, or a provider-directory mental model, translate the intent into Apps v2:

Connections v1 intent Apps v2 home
Provider directory Apps gallery / tool_applications
Configured provider instance Connection / tool_connections
Grant allowlist Profiles, profile bindings, policies
Resource filters Policy/profile conditions plus provider config
Tool broker Tool gateway and runtime supervisor
Connection UX tail Apps, Connections, Review, Developer/Advanced IA

Do not add new work to the retired v1 branch. If an old ticket still describes a valid product gap, retarget it to an active Apps v2 issue or close it as superseded with a link to the replacement.
