## Thinking Path > - Paperclip manages AI agents and their work. > - The experimental Runner owns provider processes and durable sessions. > - Pi needs working task execution and human controls. > - The five-PR stack must preserve changes already on master. > - Each layer now carries the complete integrated source for a safe sequential fallback. > - This PR belongs to native GitHub stack #15602, ending at #14956. ## Linked Issues or Issue Description Refs #14436, #14631, #14743 and #14956. Ship Pi 1.0 through the experimental Paperclip Runner. The five PRs are #14921, #14922, #14923, #14924 and #14956. The user authorized the complete merge after checks pass. Existing `pi_local` execution is unchanged. Accounting and wider provider/platform qualification remain deferred. ## What Changed - Recover missing final replies after workspace finalization changes owners, using accepted-turn evidence without rerunning work or granting external-chat publication. - Preserve the admitted Pi instruction root across warm runs, while retaining changed-root rejection. - Give Pi a bounded 15-second default shutdown grace so stop, drain acknowledgement and durable suspension can complete. Explicit deadlines and other providers retain their existing behavior. - Integrate the Pi 1.0 runtime and master contracts. - Use Pi profile 22. Preserve explicit caller-selected models and exact native thinking levels. Keep Pi's wrapper, helper, extension and question/control behavior unchanged from the qualified profile-19 runtime. - Preserve master's Dot lifecycle and consent fields, configured task environment, status guards and current Codex/Claude dependency versions. Cursor stays qualified. Copilot stays pending; profile 17 binds the changed shared protocol validation sources. - Exclude general AWS IAM credentials from Pi static/custom provider bindings and selected task projections; preserve the provider-scoped Bedrock bearer key. Profile 21 is retained as historical provenance. Rust and cloud install probes use the current declaration. - Patch bundled brace-expansion 5.0.9 to the exact official 5.0.12 payload. Pin the patch and complete runtime closures. Include the patch in normal installed setup tooling. Keep the upstream Pi shrinkwrap as provenance and permit only this exact security correction. - Include current attestation files in the Docker build context. Keep the repository lockfile unchanged from master. CI and private image builds resolve manifest changes before their frozen installation. ## Verification - Full local `pnpm -r typecheck` passes, including Runner Rust, server and UI. Focused integration checks pass: 194 Runner admission/environment tests, 63 profile/credential tests with one expected skip, 152 Dot/UI configuration tests, and Pi transcript/notice tests. - Full local `pnpm build` passes on the final source. - Fresh final-source checks pass: all 698 Rust workspace tests (32 binaries), 156 credential/profile/controller tests with one expected skip, Runner TypeScript typecheck, and 20 package/setup/sandbox tests. - The profile-21 Pi materializer passes on the native host with the official pinned Node 24.21.0 and its npm. It verifies all 150 locked packages, the patched dependency and the exact closure. Setup/package bundle tests and UI token gates pass. - The old hashes were reproduced for all three supported targets before calculating the patched graph. New closure hashes are darwin-arm64 `282022db10150c6632b3444df421342e7d534bdf5d5fb1097a2e79d0625a2bcf`, darwin-x64 `64e251e19009f755c0b04f73ce2138246faab71a961b0f13d75ebfcc34bef12e`, and linux-x64 `713b1fdff42fb56a1518bdc084f181d70bee8ebadc3e4b1d76321ed9108c8410`. Independent native platform execution is separate from graph identity reproduction. - Historical cloud qualification remains unchanged: all seven core cases pass on shipping source `10dc43c9ec65d88c2f782d62afb296d09494f215`, harness `1a4408a48cfb5a1f094a311141c257c92cd7a893`, image `sha256:5b3a775b383591bda1b0c1889e509acc70ce7f37c53f09733c81d59037f02280`, and accepted Sonnet 4.6/low fixture. All 215 canonical files and all seven cleanup checks pass independent verification. These are profile-19 results and are not relabeled as fresh profile-22 runs. - Current Pi digest: `sha256:e92078bee3c23bec4100aa589013a44613d054cd686826534025d8019e9f39a9`. [The readiness plan](https://github.com/paperclipai/paperclip/blob/codex/pi-production-readiness/doc/plans/2026-10-02-pi-production-readiness.md) preserves campaign and failed-attempt provenance. - Merge only after every PR's current-head CI and fresh review pass. Linux CI covers the full suites, build and browser tests. The local embedded Postgres API-authority suite cannot start on this macOS/Node 26 host, so Linux CI must confirm that suite. ### Fresh profile-22 core qualification — 2026-10-08 All seven accepted core cases pass canonically on Pi profile 22, with `openrouter/anthropic/claude-sonnet-4.6` and native-confirmed low thinking. This model is a fixture; production accepts the caller's explicit Pi provider/model. Runtime/install source: `3241a992f2a7703e59e97ed0fd3e5d6405de4401`. Frozen accepted harness: `1a4408a48cfb5a1f094a311141c257c92cd7a893`. Immutable cloud image: `ghcr.io/paperclipai/paperclip-daytona-runner@sha256:506f22db7edd78f37c0c40bec1cc084af1850455026dbf467194bfbb8fcef141`. Pi digest: `sha256:e92078bee3c23bec4100aa589013a44613d054cd686826534025d8019e9f39a9`. [Hosted Linux image and clean-install verification](https://github.com/paperclipai/paperclip/actions/runs/37868328023) passes, including all 20 source-bound archives, normal CLI/Pi setup, companion import and the production pack reader. This exact installation source includes the latest master integration and the corrected Pi warm instruction-root fence. Full local typecheck/build and current-head hosted CI verify the final stack. All 13 focused real-root regressions pass. The full local executor suite passed 662 tests; 15 database tests could not start the Mac embedded PostgreSQL service. Hosted Linux CI passes the full required verification and E2E checks. These fresh results keep their own source identity; profile-19 results remain historical. | Core path | Canonical campaign | Retained archive SHA-256 | | --- | --- | --- | | File edit, validation, download and Done | `pi-core22-replyfix-0-1791511228` | 23 files; `a473e8603a3dd4737863291f8d3d1e392391f0b16d433c3e0e0e9d8baf7a97b0` | | Pending question and controller restart | `pi-core22-replyfix-1-1791511376` | 33 files; `6b829c4eb74e1f32a89c692a4ae7130dbfc1c6d3cf13915effe2103d9e242c8e` | | Three-turn session/process/workspace continuity | `pi-core22-replyfix-2-1791511587` | 23 files; `7a87021f8f9a3fdd3c58bb4467f8d82c635e3ea4795d6e75f144d9aa14818df8` | | Four typed questions and browser reconnects | `pi-core22-replyfix-3-1791511881` | 42 files; `9e31755252be1f4f9cb0626c984c142d4d1ae5f5bee3a7af08444db8d12c280a` | | Plan approval and completion | `pi-core22-replyfix-4-1791512031` | 22 files; `a0383ce1aab38e7b5a25ce0e9dd3bebea5c037ebd96ae6b29dae19015da2ae2c` | | Same-turn steering and permission denial | `pi-core22-replyfix-5-1791512261` | 39 files; `c929b8c7070f0b66aedc17e65ca46e6beab1e363926ac9f7e2a75fb250f05949` | | Stop during pending permission | `pi-core22-replyfix-6-1791512390` | 33 files; `7f0a58ae0f4d5bfc76149435f4e322537089c5bd16e7ffe9b5ad71f10a621a07` | All 215 canonical files (28714587 bytes) are independently hash-verified. All seven cleanup grades pass, with no owned runtime process or temporary root after each case. Automatic retries are zero. The owned cloud host stopped normally after retention. The prior profile-22 warm attempt remains failed and separately retained: archive SHA-256 `1e54eba5ec72b50cee1534b23d1d1d4f21a090006b8a64501ba70db972abfde5`. Its original canonical classification is preserved. Diagnosis reproduced a product bug comparing an agent-files root against an unset checkpoint-only field. The fix stores the admitted physical root separately from the adopted per-run collection capability. The real-root regression fails before the fix and passes afterward, including rejection of a changed physical root. Fixture, grader, model and all seven accepted case IDs are unchanged; this fresh campaign tests final-reply publication after file registration first. The intermediate restart attempt also remains failed and retained: archive SHA-256 `5dcaefdf1d17cf4cd54fd4cf810f45e736667392339b8ce7caf08bb4e225277f`. Its original canonical classification is preserved. Pi resumed, wrote the verified answer and completed its task; exact runner suspension was proven, but idle stop consumed about 5.2s and left under 3s for the drain acknowledgement. The Pi-only default shutdown grace is now 15s, preserving a full 5s drain round trip and a finite suspension reserve. Explicit caller deadlines, other provider defaults, literal drain receipts and exact suspension identity checks remain unchanged. The timing regression fails before this correction and passes afterward; all 18 focused settlement tests and Runner typecheck pass. The final-source file attempt is also preserved as failed (`candidate_failure`), archive SHA-256 `db6767b6773ea618997927ac77bdb005a5ac81492c7b9c0ffbc900449f829bc9`. Native edit, validation, exact downloadable artifact and Done/succeeded all passed, and the exact final reply was durably recorded. A workspace recovery owner completed before the live heartbeat reached presentation, leaving that reply absent from task chat. Recovery now materializes only a completed final reply from the accepted turn of an ordinary internal Done task, preserving issue/run/contract binding, suppression, external-chat authorization and same-run deduplication. The database regression covers the generated file-preparation receipt, suppression, unapproved external continuation and replay. Server typecheck and all 49 response-selection tests pass; hosted Linux verifies the database regression because embedded PostgreSQL cannot start on this Mac. The delayed-final-answer database regression passes on [the final root-source Linux server shard](https://github.com/paperclipai/paperclip/actions/runs/37868262553/job/113628594152), alongside 1,108 passing tests. The first root Runner shard had one unchanged durable-resume test exceed its 5-second timeout; the identical top-source shard and the isolated exact test passed. One rerun of that failed job and its required aggregate passed without source or test changes. The original failed job log and the single-rerun receipt remain retained. ### October 9 merge verification Current merge head: `5a8fe63512a7166aaef5cf50065a25008aa8b44b`. All current-head checks pass, including `ci / verify` and `ci / e2e`; exact-head Greptile review is 5/5 with no unresolved threads. Current master conflicts are resolved. The user authorized the maintainer override of the code-owner review gate after these checks. The seven retained live core cases remain bound to source `3241a992f2a7703e59e97ed0fd3e5d6405de4401` and its recorded cloud image. ## Risks - The security correction changes the dependency closure and profile identity. Old sessions must reopen on the new profile. Exact identities and credential bindings fail closed. - The runner remains experimental and requires explicit selection. Legacy Pi Local is unchanged. Caller model IDs pass through; the E2E model is a fixture. - Accounting and the broad platform/provider matrix remain deferred. This merge does not publish a release or deploy a service. ## Model Used OpenAI GPT-6 through Codex assisted with reasoning, repository inspection, editing and tool use. The exact serving ID and context window are not exposed in this session. Final live qualification uses Pi 1.0.0 with `openrouter/anthropic/claude-sonnet-4.6` and native-confirmed low thinking. ## 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 #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] 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 any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
Paperclip Daytona runner image
Ordinary provider packs now include pinned Cursor assets for Linux x64; no
--candidate-providers=cursor flag is needed. Cursor admission is enabled after
the production readiness gates
passed. The public CLI installation command is paperclipai runtime setup cursor;
it runs explicitly on the execution host and is never an npm installation hook.
This image is the Paperclip Cloud fleet sandbox image plus a source-built
paperclip-runnerd and immutable provider pack. The pack contains Node 24.11,
OpenCode 1.18.34, the compiled OpenCode proxy, ACPX 0.13.1 sidecar, qualified ACP
agents, and the production lockfile. Its manifest digests each executable bridge
and binds the pack to the runner source revision, avoiding artifact upload and
npm installation on every fresh lease.
The fleet pins are intentionally copied from
paperclip-cloud/fleet-sandbox-image/Dockerfile.
Update both definitions together until the fleet base is published as a stable
image that this Dockerfile can extend directly.
Harness versions
The October 2026 refreshes pin Codex 0.160.0, Claude Agent SDK 0.3.286 (Claude Code 2.1.286), and OpenCode 1.18.34 in the shared provider pack. Claude Code 2.1.280 is the minimum for Opus 5.5 and 2.1.284 is the minimum for Sonnet 5.5; the pinned runtime also supports Fable 5.1. Codex 0.160.0 ships bundled metadata for the current GPT-6.1 Sol, GPT-6 Sol, and GPT-6 Luna model IDs. The same refresh pins Grok CLI 1.0.46, Gemini CLI 0.62.0, Kimi Code 2.1.1, Cursor CLI 2026.10.01-e373342, and GitHub CLI 2.102.0 in the sandbox layer. The native Cursor provider uses its separately verified distribution, pinned to 2026.09.26-dd393fe; it does not use the sandbox layer’s global Cursor executable. Grok CLI 1.0.46 supports the current Grok 4.7 model family. Hermes stays at 0.19.0, the newest release on PyPI.
Keep the patched ACP bridge versions separate from their CLI runtime pins. Their executable digests do not change when only the runtime dependency changes. Refresh the runtime executable digests from integrity-verified npm release archives for every supported platform, and keep the native runner, provider manifest, and remote controller version checks aligned.
Build and verify
Run pnpm --filter @paperclipai/paperclip-runner test:opencode:qualification
after installing dependencies to exercise the actual pinned OpenCode executable.
It checks health/version, session creation and retrieval, SSE messages, an async
prompt, and session deletion against a loopback mock provider. It uses an
isolated home, starts no paid model request, and retires its process group.
Set PAPERCLIP_TEST_OPENCODE_BINARY to the materialized Linux executable when
qualifying an assembled provider pack.
The fleet image is currently amd64-only because the pinned Cursor and GitHub CLI checksums cover amd64.
content_id="$(pnpm --silent test:e2e:runner:image-id)"
docker buildx build \
--platform linux/amd64 \
--build-arg PAPERCLIP_RUNNER_CONTENT_ID="${content_id}" \
--build-arg PAPERCLIP_RUNNER_SOURCE_REVISION="$(git rev-parse HEAD)" \
--tag "paperclip-daytona-runner:e2e-content-${content_id}" \
--load \
--file docker/daytona-runner/Dockerfile \
.
docker run --rm --platform linux/amd64 \
--entrypoint paperclip-runnerd \
"paperclip-daytona-runner:e2e-content-${content_id}" \
--build-metadata
The metadata must advertise dial_ws_loopback, dial_wss, and listen_ws.
The explicit entrypoint is needed only for this local probe because Daytona's
base image uses its own long-running sandbox entrypoint.
test:e2e:runner:image-id hashes the audited Docker build dependency closure,
target platform, the immutable Dockerfile syntax-frontend digest, and every
immutable FROM reference. It fails before the paid workflow can build when
the frontend or a base is not pinned to a sha256 digest. When updating the
syntax version, resolve and review its registry digest and update both values in
the first Dockerfile line. Git commits that do not change those inputs reuse the
same content tag.
PAPERCLIP_RUNNER_SOURCE_REVISION remains the full Git SHA that built the first
published copy and is retained as provenance rather than cache identity.
Use in Paperclip
Publish the image to a registry Daytona can pull, or use the environment
editor's Configure image flow to produce a Daytona snapshot. Set the
environment image to that immutable tag or snapshot. Paperclip probes the
sandbox user's PATH for paperclip-runnerd and codex and checks
/opt/paperclip-runner/provider-pack for OpenCode and ACPX. It uses the pack
only when its complete manifest matches the controller's build-owned pack;
otherwise it stages the pack configured by
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH. Remote OpenCode and ACPX never
fall back to host-local processes.
Do not promote paperclip-runner-e2e-20260826-v2 for OpenCode or ACPX. Build a
new immutable image or snapshot from a clean committed revision and pass that
full Git SHA as PAPERCLIP_RUNNER_SOURCE_REVISION.
Do not bake provider credentials, Paperclip bootstrap tickets, or Daytona preview tokens into this image. They remain per-run secret material.
The provider-pack build pins the official Linux x64 Node 24.21.0 image by manifest digest. Its bundled Undici is 7.29.1, which fixes GHSA-3wwx-pv8p-q78v. Pi separately verifies its private Node executable and nested npm dependency; changing the outer interpreter does not replace either provider-owned pin.
Provider CLI updates are manifest-only changes: repository CI owns the root
lockfile. Resolve the complete workspace manifest graph in the build context
before invoking Docker, matching CI when a source commit precedes the lockfile
bot. The trusted workflow supplies this resolved lockfile as an immutable artifact.
The complete resolved lockfile must match PAPERCLIP_RUNNER_LOCK_SHA256 before
package installation or lifecycle execution. Review and refresh that digest
with source dependency changes; registry-time resolution drift fails closed.
The Product E2E workflow resolves one lockfile before the image build. It
verifies the downloaded artifact, then passes that artifact's SHA-256 as the
PAPERCLIP_RUNNER_LOCK_SHA256 build argument. The Dockerfile checks the resolved
lock against this value before installation. The fixed Dockerfile default is
for standalone builds; it must not replace a campaign's verified lock digest.
Refresh the default from the clean tracked lockfile using the exact
pnpm install --resolution-only --ignore-scripts --no-frozen-lockfile command,
and verify a second resolution preserves the digest. A lockfile left by a
filtered or incremental install can retain stale importer patch identities.
Refresh exact runtime versions and qualification digests together; do not
download dependencies when a task starts.
Candidate ACP qualification assets
Provider branches can build their pinned assets with
node packages/paperclip-runner/scripts/build-provider-pack.mjs /absolute/pack --candidate-providers=cursor
(or copilot or pi). The source revision must include the named provider's
builder. Assets are installed at build time under provider-assets/<provider>/<platform>-<architecture>.
The pack manifest binds each complete asset tree. Runtime admission separately
checks the provider's source-owned closure pins and copies a verified launch snapshot.
A pack with candidate assets does not qualify or enable that provider.
For an isolated Linux x64 Daytona qualification image, pass
--build-arg PAPERCLIP_RUNNER_CANDIDATE_PROVIDERS=cursor with the normal build arguments.
Compute its content ID with the same selection:
pnpm --silent test:e2e:runner:image-id --candidate-providers=cursor.
Candidate assets and the default pack have distinct image identities. Never reuse
the default image's content ID for a candidate build.
Use each provider branch's recorded version and explicit model. Keep credentials
out of images. Paid qualification requires bound provider and Daytona credentials,
inspectable spend, and the shared $100 ceiling recorded in the capability report.
The pack builder tests its copied Node interpreter after relocation. Use a
standalone Node distribution if the host interpreter depends on a package manager's
private shared libraries. Pi additionally pins its complete portable interpreter
and npm dependency graph.
Refresh exact runtime versions and qualification digests together; never download
dependencies when a task starts. Grok's additive native ACP profile keeps its
qualified 1.0.13 executable at the verified sandbox prerequisite path. It does not replace the
legacy adapter's grok command on PATH.
Native Grok is an image prerequisite at /opt/paperclip/providers/grok/1.0.13/grok.
Its checksum-verified provisioning is separate from the provider pack, which ships
only the built-in launcher. Public npm installation never downloads this binary.
