## Thinking Path > - Paperclip manages AI agents and their work. > - Native agents use authorized API tools to read saved results. > - Copying a large response as model-generated text can lose bytes. > - The execution workspace needs an exact copy of the saved artifact. > - This change copies the authorized bytes without shell API credentials. > - The runtime verifies size and SHA-256 before it reports success. > - A live evaluation checks capture origin, installation and delivered bytes. ## Linked Issues or Issue Description **What happened?** A native agent lost one byte while copying a 24576-byte API text page. Existing capture and paging controls passed. The runtime had no verified saved-artifact-to-workspace copy tool. A separate historical screening refusal does not establish capture corruption. **Expected behavior** An authorized native run can install the complete saved artifact. The stored and installed bytes must match in size and SHA-256. A conflicting file must remain unchanged. A lost publication receipt must not cause an unsafe repeated write. **Steps to reproduce** Run `server/src/services/native-runtime/artifact-transfer.integration.test.ts` on baseline `c46b8f35add9255fc71be294d27f5a7865bcb47f`. Its capability assertion fails because `download_artifact` is absent. Apply this PR and run the same regression with the filesystem and API controls. It verifies 388131 synthetic bytes through the authority and installation boundary. Refs #18429. Related #17393, #17086 and #17285 cover paging, transfer foundations and remote output reads. This PR adds the inbound installation contract. ## What Changed - Add `download_artifact` for supported standard-mode native runs, with a 10 MiB limit. - Reuse current company, task, run, asset-content and responsible-user access checks. Check authority again before publication. - Bind installation to the current execution lease. Stage through confined Linux descriptors and publish with an atomic create-only link. Keep API credentials out of execution commands. - Verify bytes at storage and execution boundaries. Reject unsafe paths, symlinks, different existing files, truncation and corruption. Reconcile an unknown publication through verification only; an identical explicit retry remains safe. - Add API documentation, access-map entries and content-free audit records. - Preserve only the pinned Daytona SDK numeric HTTP status when failed creation cleanup is unconfirmed. Keep provider exception messages and headers private. - Keep only the finished runner binary and portable provider pack in their builder layers. Remove Rust targets/downloads and the Node install workspace/store before export. Report tree sizes. - Add one explicit Codex/Daytona Product E2E cell. Its independent oracle checks the server capture audit, redacted tool receipts, stored source, delivered attachment and browser link after reload. Uploaded substitutes and one-byte loss fail. ## Verification - Merge update at `6766b46553cab5b9787ade87a002eccaf50e68fc`: merge current master and preserve both explicit suites in the catalog. Focused catalog, image and oracle checks: 122 pass. Filesystem and authority integration: 20 pass. Maps, module boundaries and whitespace checks pass. New-head CI and Greptile are running. Full local build and typecheck remain unavailable because cargo is absent. - Behavioral red/green: the absent-tool regression failed before implementation and passed afterward. The initial missing-package attempt is recorded as setup failure. - Linux filesystem and real PostgreSQL/authority integration: 19 filesystem tests and 1 authority test pass. Existing API authority, capture and paging controls: 70 pass, 2 skipped. Provider transport in these integration controls is simulated. - Qualification calibration: 118 focused tests pass. The real persisted-event redaction case and a byte-identical uploaded substitute each failed before their oracle repair. The unchanged controls then passed. Harness typecheck passes. - Full recursive typecheck and build pass locally on the integrated production source at `086f7a2901`. Later commits change only qualification tests and documentation. - Structural map/module checks and whitespace checks pass. - Full local `pnpm test:run` was attempted by the implementation worker and stopped under its 8 GiB memory limit, with no full-suite verdict. Current-head CI must supply the full test result. - The complete local Product E2E support suite has 13 failures. The unchanged pre-qualification baseline reproduces all 13: host PostgreSQL semaphore capacity, stale timeout/profile/workflow inventory expectations, and expired fixed-date allowance fixtures. This is not a full local suite pass. - Earlier CI at `086f7a2901` failed a browser test during cleanup cancellation with a database lock timeout. It remains recorded. All browser shards passed on both later fully checked heads. - Two qualification campaigns were canceled during setup before provider execution while correcting the oracle. They provide no live product verdict. - Previous-head CI at `28fa001457f59df1c300c016dc569049e72d0061`: 53 checks pass, 3 intentional selection skips; no failed or pending checks. - Real image/export regression: campaign 41272351780 compiled the Linux runner and passed root/unprivileged CLI and transport checks, then failed BuildKit export with `no space left on device` (exit 102, filesystem 99.99%). No provider cell ran. Removing the Rust build trees alone was insufficient: campaign 41273604815 also failed during provider-pack export with exit 102. Commit `5bbb549c54` also consolidates dependency installation and pack construction so the disposable workspace/store can be removed in the same layer. All 122 image/oracle/catalog checks pass. Image and remote-pack publication then passed in campaign 41275196741 after cleanup changes plus a scoped 60-to-120 GiB expansion of only its delete-on-termination builder disk. The VM terminated and the expanded volume was deleted. This does not establish that cleanup alone makes the default 60 GiB builder sufficient. - The Daytona admission probe then failed before agent creation, with unconfirmed provider cleanup. The queued continuity case was canceled because it shares this prerequisite. No artifact-transfer or continuity success is claimed. - Status-diagnostic regression: the original generic wrapper failed the HTTP-status assertion. After the repair, the full plugin suite passes 501 tests, with 7 skips; its standalone TypeScript check passes. Controls reject invalid status values, avoid accessors, preserve the original create status and exclude credential canaries. - Previous-head Greptile: 5/5; its summary names `28fa001457f59df1c300c016dc569049e72d0061`. All review threads are resolved. - Live artifact transfer and three-turn warm continuity: NOT VERIFIED. The diagnostic case in https://github.com/paperclipai/paperclip/actions/runs/41277598289 confirmed Daytona HTTP 401 before agent creation. The configured `DAYTONA_API_KEY` in the existing `runner-e2e-paid` environment needs verification or refresh. The queued continuity control was not run after its shared admission prerequisite failed. No further provider attempt is planned until the credential changes. Unconfirmed provider cleanup remains recorded. ## Risks - Source-provenance changes can repeat the provider dependency install. The combined build layer trades install-cache granularity for lower retained disk use. - Linux descriptor semantics and Node are required on the execution host. Unsupported providers and restricted runtime profiles fail closed. - Storage reads buffer at most 10 MiB. A provider outage can leave a reserved staging file. Partial bytes never become the destination. - A lost publication receipt can leave a complete file with an unknown result. Recovery verifies the existing file without installation. Conflicts are never overwritten. - Artifact contents remain untrusted. The copy does not bypass screening or authorize downstream execution. - Live qualification uses the governed Codex API profile. It does not establish every model, subscription profile, platform or historical failure cause. ## Model Used OpenAI GPT-6 in Codex assisted with diagnosis, code, tests and qualification. The desktop runtime does not expose a more specific model deployment ID or context-window size. The model used reasoning, source inspection, tools and code execution. The native implementation agent is configured with OpenAI `gpt-6.1-sol`. ## 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 #` / `Refs #` 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 - [ ] All Paperclip CI gates are green - [ ] 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: devinfoley <139239+devinfoley@users.noreply.github.com> 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 records the runner source revision as provenance. Its interface declaration
allows compatible app releases to reuse it without uploading or installing a pack.
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 sandbox layer pins Grok CLI 1.0.70, Gemini CLI 0.65.0, Kimi Code 2.3.3, Cursor CLI 2026.10.22-27dcf5f, and GitHub CLI 2.103.3 (October 2026 refresh). 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 1.0.70 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.

--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
when its selected provider interface and platform are compatible. App source
revisions and unrelated provider pins do not force an update. Startup reads the
small manifest in the existing runner metadata query. It does not scan the pack,
run a version command, or transfer files on this path. Otherwise it stages the pack configured by
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH. Remote OpenCode and ACPX never
fall back to host-local processes.
src/live/provider-pack-contract.json in the Runner package declares the
OpenCode and ACPX interface revisions. Change a revision only for an incompatible
runner/pack boundary change, and qualify the new pack before publishing it.
Bumping a revision also retires every older image pack.
The pack build also records a contractDigest, computed by
scripts/contracts/contract-fingerprints.mjs from the JSON contracts under
protocol/ and generated/, from Rust serde shapes, payload keys, match
literals and env keys, and from the Runner's ACPX patch, rather than from
source bytes. An image pack is reused
only when its digest equals the controller's bundled pack; comments and
refactors leave it unchanged, so a mismatch means a contract changed and the
controller uploads its bundled pack. Packs without a digest are not reused.
Define a new runner/pack contract in a schema under protocol/ and generate the
TypeScript from it, as the sidecar's session.open parameter allowlist is
generated from acpx-sidecar.schema.json; TypeScript-only definitions are not
part of the digest.
Dependency versions and Git SHAs remain build provenance. ACPX retains its
selected agent's qualified profile checks.
The image build makes the pack root-owned and non-writable to the execution user. Fast admission requires protected ancestors and manifest, with no writable path alias. Task-owned packs and older packs without an interface declaration keep full content verification. An attached session retains the exact pack and daemon identity admitted at launch. Publish one new image with the interface declaration to enable reuse across later compatible app releases.
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.
