## Thinking Path > - Paperclip manages AI agents and governs their work. > - Its native runner uses structured provider protocols for sessions and tools. > - Grok Build supports ACP over stdio, but the runner did not expose it. > - Native execution requires company-scoped credentials, verified identities, and permission gates. > - This change adds Grok through ACPX for local and Daytona execution. > - Subscription login and explicit API-key execution have separate credential paths. > - Qualification grades real tool outcomes, durable state, and browser workflows. ## Linked Issues or Issue Description Refs #13845, #13847, #13850, #13878, #13901, #13973, #13977, #13979. Add **Grok Build** to `paperclip_runner` with `provider: "acpx"`, `acpxAgent: "grok"`, and model `grok-4.7`. Existing legacy Grok agents keep their adapter. Merge the three companion fixes (#13973, #13977, #13979) before treating the integrated Product qualification as deployed behavior. ## What Changed - Synchronize shared, TypeScript, Rust, server, validation, and UI provider contracts. - Run Grok native ACP stdio through ACPX and the authenticated Paperclip MCP bridge. Verify the pinned executable and exact ACP model identity. - Prefer company subscription login. Support an explicit company-secret API key without automatic paid fallback. Fence refresh and copyback to the same account and remove private runtime credentials after containment. - Preserve selected permissions, cancellation, durable session identity, resume, and restart recovery. Keep unsupported steering and goals unavailable. Preserve missing usage and cost as unknown. - Package checksum-verified Grok Build 1.0.13 for Daytona with an immutable, signed image built on EC2. - Add deterministic admission, protocol, permissions, identity, credential, failure, and cleanup checks. Add the maintained 39-case protocol roster and separate subscription/API Product profiles. - Fix live-test findings in reasoning events, reloads, idle-owner retirement, credential-home cleanup, expired-login model discovery, launcher pinning, and rerun evidence selection. - Align control-plane state readers with the transport's 64 MiB bound while retaining identity, ownership, lifecycle, and size rejection checks. - Stabilize two asynchronous CI assertions while retaining actual outcome and filesystem-evidence checks. ## Verification Current integration head `f114948376056fe0b6b34c1496ae8667b59daa63` includes master `3447609d2247e75e55d91493dda91a608364f672` (2026-09-28). Two master advances during verification overlapped the eval catalog; the final merge preserves Grok qualification, completion updates, and bounded API-response reading in all 348 cells. All 77 focused catalog/eval/workflow tests pass. Both native stack layers (#14397) are mergeable, and both exact-head Greptile reviews are 5/5 with successful security scans and no unresolved review threads. All current-head CI is green: 56 successful checks/statuses and four intentional skips ([CI run](https://github.com/paperclipai/paperclip/actions/runs/36447097232)). Trunk code-owner requirements remain enforced. The review summary’s non-blocking saved-asset offset classification note concerns code already merged in #14301; those runtime files are identical to master and outside this stack’s diff. Historical live evidence below retains its original source revisions. Earlier integration checkpoint: `24fc9b94ca0afb21ccdc8d26dbb2e4b258ad72cb`. Refreshed against master `0f14d2612`, preserving Grok qualification alongside the new accounting and lifecycle suites. All 124 focused catalog, evidence, and service-worker checks pass. The current base workflow includes the explicitly selected public-install verification lane; follow-up #14024 supplies its verifier script. CI at that earlier checkpoint was green (56 successful checks/statuses, four intentional skips), and the review is 5/5 with no unresolved findings. Prior feature CI at `fd73f0a9b1ecdf4094685054028df71739ddc3e1` passed ([run 36148259902](https://github.com/paperclipai/paperclip/actions/runs/36148259902)); that is historical evidence, not a current-head result. Paid Product measurements use frozen integrated source `2d939a92b21dcaf5c77c88b54d96784d2ddd0699`, which combines the feature with #13973, #13977, and #13979. That source passed all 52 CI checks and clean 5/5 review. Later master syncs incorporate upstream changes. Their checks remain separate from these pinned live measurements. | Check | Result and source-pinned report | | --- | --- | | Subscription protocol roster | [39/39 first attempts; 206 assertions](https://d1p6rlowie26tp.cloudfront.net/runner-protocol-evals/campaigns/gha-36046839612-1/index.html), runtime `bc6833f7`, evals `92bb4b8c` | | API protocol roster | [39/39 first attempts; 206 assertions](https://d1p6rlowie26tp.cloudfront.net/runner-protocol-evals/campaigns/gha-35926577007-1/index.html), runtime `4a1061c8`, evals `3213dbec` | | Subscription full Product matrix | [16/16 first attempts; 144 assertions; cleanup passed](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-36096908572-1/index.html), source `2d939a92` | | Subscription core repetitions | 18/18: tool use, planning approval, and Stop/resume each passed three times in local and Daytona profiles. The full matrix contains repetition one; [repeat two](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-36104551060-1/index.html) and [repeat three](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-36108100404-1/index.html) each passed 6/6. Total: 28 unique subscription attempts at `2d939a92`. | | API smoke and question continuation | [4/4 first attempts; cleanup passed](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-36147315401-1/index.html), both environments at `2d939a92` | | Historical API Product coverage | [16/16 full matrix](https://d1p6rlowie26tp.cloudfront.net/runner-e2e/campaigns/gha-35875144860-1/index.html) and 18/18 core repetitions at `4a1061c8`; retained as measurements of that revision | | Native Daytona proof | Three subscription and three API MCP/permissions/resume runs passed at `bc6833f7`. Three expired-login admission and fenced refresh checks passed without inference. All test sandboxes were removed. | | Inspectable artifacts and UI | Current-source screenshots verify planning approval, direct Ask completion, question continuation after controller restart, and two downloadable project revisions. The project downloads pass 12 and 18 tests; all 40 independent artifact oracle checks pass. | | Provider-free checks | 116 eval-validator tests, 39 Grok definitions, and 359 enabled/external campaign cells pass. Continuation regressions above 2 MiB and 16 MiB failed before their fixes; 32 focused recovery/ownership/size checks pass. | The 32 unique current-source Product attempts have no failures, retries, or skipped cells, and all cleanup checks pass. Whole-workflow timing, model identity, image and provider-pack provenance, attempts, and accounting coverage are retained in the canonical reports. The report publisher's conservative `complete=false` flag is preserved; independent audits verify the exact selected source catalog and immutable result rows. Pins: Grok Build `1.0.13 (5e9a58528b76)`, ACPX `0.13.1`, ACP model `grok-4.7`. Linux binary SHA-256: `edf79521581bb5e6b95abef848491a6a742e860da3e237ebe86a280d30dce4c1`. Launcher SHA-256: `f0b698395a3704ed2ffaf84ea19bdb20c36c8a0a70b7c629c7b6ffe144e59e55`. Image: `ghcr.io/paperclipai/paperclip-daytona-runner@sha256:76b24edfd850219e949418b19e4ceba690e84d51d199ade426e484953329b5e9`. Image build source is `4196a4cd`, recorded separately from application source `2d939a92`; each campaign verifies the image signature and provider pack. Original failed campaigns remain available: [continuation bound](https://github.com/paperclipai/paperclip/actions/runs/36057718059), [scheduler/event capture](https://github.com/paperclipai/paperclip/actions/runs/36071063537), and [startup cleanup plus EC2 interruption](https://github.com/paperclipai/paperclip/actions/runs/36080870743). They retain their original grades. No Docker or Rust builds ran on the developer laptop for these follow-ups. ## Risks Merge packaging follow-up #14024 with this base before public release. The follow-up replaces the private Grok bridge package with a built-in launcher and makes the native binary an explicit sandbox prerequisite. Three separate, reviewed fixes are part of the tested integrated behavior: #13973 serializes task-run admission; #13977 captures complete event evidence; #13979 durably reconciles failed Daytona creation. Each has green CI and clean 5/5 review. Failed-create recovery has 277 plugin tests, 92 SDK tests, host-runtime recovery tests, and a real Daytona lost-deletion-receipt proof. The live proof uses a private file for journal persistence; database durability is covered by host tests. Worker death before delivery of a failure envelope remains outside that recovery mechanism. Subscription fixtures stage an authorized company login; interactive browser sign-in is not qualified. Local Product profiles ran on EC2 Linux. The temporary subscription credential was removed from the protected GitHub environment after all subscription audits, with absence verified. Runtime homes and refresh copyback remain ownership-fenced. Protocol results remain pinned to their original revisions; they are not relabeled as tests of the latest feature commit. New binary/model versions require qualification. Missing token usage and model cost remain unknown; runtime estimates do not establish a full bill. Automatic paid Grok scheduling remains disabled pending separate reviewed enablement. The 64 MiB bound can increase memory use for verbose sessions, and larger files still fail closed. No automatic legacy-agent migration occurs. ## Model Used OpenAI GPT-6 through Codex, with tool use and code execution.

Paperclip Daytona runner image
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 1.18.32, 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 September 22, 2026 refresh pins Codex 0.156.0, Claude Agent SDK 0.3.280 (Claude Code 2.1.280), and OpenCode 1.18.32 in the shared provider pack. Claude Code 2.1.280 is the minimum for Opus 5.5; it also supports Fable 5.1. Codex uses the current GPT-6 Sol and Luna model IDs. Grok CLI 1.0.41 supports the current Grok 4.7 model family.
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.

--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.
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 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 a verified package path. It does not replace the
legacy adapter's grok command on PATH.
