DottaandPaperclip a6306ba606 feat(runner): consolidate Cursor production integration (#15075)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The native Runner keeps provider sessions under company authority,
approvals, budgets and durable recovery.
> - Cursor work was spread across candidate branches. The published
branch lacked later plan, permission and cleanup fixes.
> - Production also needs public installation and matching runtime
assets for local and Daytona execution.
> - This pull request consolidates Cursor onto current mainline recovery
behavior and completes that installation path.
> - The installed v11 release passed focused local and Daytona
qualification after the generic mode and lifecycle cleanup. The later
model-selection correction and current mainline merge produce v14
artifacts that need matching release qualification.
> - Cursor admission is enabled in source; publish only an artifact
combination with matching qualification. Native AskQuestion and complete
per-run dollar accounting remain excluded.

## Linked Issues or Issue Description

Refs: #14435, #14631, #14669, #14699, #14724.

This completes the Cursor implementation by @cryppadotta from combined
source `22c78242a4e0c2369fecf0c2dc4e7600fbad6706`. It preserves newer
mainline recovery, completion and warm-directory behavior. Pi and
Copilot remain gated.

## What Changed

- Generate named Rust and TypeScript ACPX release profiles from one
manifest. Share runtime pins with packaging and server verification.
Preserve vendor runtime versions; bind the updated ACPX patch to Cursor
profile v14 and reject stale generated declarations at build/typecheck.
- Remove ACPX model allowlists, including the former Codex and Pi
restrictions and the duplicate developer test-drive gate. Send any
explicit model ID unchanged to its provider and verify the effective
selection before prompting. The bundled ACPX package forwards unlisted
IDs, rejects mismatched acknowledgements, and restores the exact
selection after session load. It does not expand Cursor model aliases.
Provider rejection, mismatch, or missing model controls fails without a
fallback. Model examples live in evaluation fixtures, outside runtime
declarations.

- Add pinned Cursor execution, contained instructions, exact model
verification and Agent/Plan/Ask modes.
- Carry an opaque generic `mode` identifier in shared native execution,
sidecar, Rust and recovery contracts. The provider adapter owns
supported modes, defaults, native translation and acknowledgement.
- Keep native RPC recognition, accepted-plan interpretation and
permission evidence behind provider adapters. Shared settlement and
recovery verify normalized facts and their committed evidence.
- Replace the Cursor-only warm-attachment branch with a runner-owned
capability. Only Cursor opts into it. Move profile compatibility and
optional usage parsing into provider metadata and adapters.
- Write generic plan-wait receipts. Read exact historical Cursor
receipts through a separate compatibility decoder. Reject mixed formats
and preserve existing authority checks.
- Carry native plans, semantic questions, todos, child activity,
permission identities and partial usage diagnostics through the Runner.
- Preserve durable response delivery, cancellation, warm ownership and
process retirement.
- Finish accepted planning runs successfully. Keep their tasks open for
explicit direction. Acceptance does not start implementation.
- Ship `paperclipai runtime setup cursor` and its provisioner through
the public package. npm installation does not download Cursor. Setup
uses the OS account's closure-keyed cache so system-wide npm packages
can remain read-only. Run it as the Paperclip service account.
- Include Cursor in normal provider packs and Daytona images for macOS
ARM64/x64 and Linux x64.
- Reject stale release packs by source revision and current ACPX/Cursor
pins before assembly writes files. Verify current Cursor
version/profile/closure again at runtime.
- Ship all three daemon targets and the expected Linux image-pack
identity. A macOS controller uses its packaged Linux daemon for Daytona.
Image mismatches fail before provider launch.
- Use the vendored Runner boundary for installed readiness probes.
Verify the actual installed Cursor probe.
- Verify compiled public Daytona plugins and their release versions in
installed smokes.
- Record exact artifacts, the acceptance matrix, retained failures,
supported capabilities and rollback behavior in the [readiness
report](https://github.com/paperclipai/paperclip/blob/codex/cursor-production-readiness/doc/plans/2026-10-03-cursor-production-readiness.md).

## Verification

- Current head `f7ec5cc1f0e30c62a829c016ff2013a2a9d79037` merges
mainline `faa8e452c73bae5e044dd6379179a00106abb131`. It keeps Cursor
plan and cancellation guards alongside mainline historical-question
filtering. The evaluation catalog includes both Cursor and expanded
adapter accounting cases (683 total). Recursive typecheck, full build,
696 lifecycle/recovery tests, 45 fixture tests and fixture typecheck
passed. Current-head CI passed: 56 successful checks, one neutral and
four skipped. [Complete
CI](https://github.com/paperclipai/paperclip/actions/runs/37557996535).
The fresh Base Greptile review is 5/5 on this exact head, with 304 files
reviewed, zero new comments and zero unresolved threads. The user
authorized overriding the CODEOWNER review gate after checks passed; no
failing checks are overridden. Prior results below retain their own head
identities.
- Corrective head `3d2b168366258036f6b6a6fccb382c49138cc601` fixes the
post-merge Apex finding. Automatic-review and new-evidence
reconciliation preserve pending child results and recheck delivery under
the status lock before completing. Account repair now excludes unrelated
secret consumers and requires the failed agent's identity. Regression
coverage includes the commit race, delivery statuses,
current-run/current-intent exclusions, repeated reconciliation, both
database reconciliation paths, and credential consumer boundaries. All
184 affected tests, server typecheck and server build passed.
Current-head Base Greptile review is 5/5, with 304 files reviewed, zero
new comments and zero unresolved threads. Current-head CI passed: 56
successful checks, one neutral and four skipped. [Complete
CI](https://github.com/paperclipai/paperclip/actions/runs/37535994724).
This Base review is distinct from the earlier Apex review.
- Merge head `5957c257a` reconciles mainline `b508a05c4`. It preserves
both accepted-plan waits and pending-child-completion checks, current
provider selectors, task-creation response identities, and mainline ACPX
missing-file handling. The combined patch is bound to Cursor profile
v14; historical records keep their original identities.
- Merge head `5957c257a` passed recursive typecheck, full build, 43
installed ACPX/package contracts, 107 provider UI and plan/recovery
tests, 593 database-backed lifecycle tests, 49 profile/native contract
tests, 45 Product E2E fixture tests, fixture typecheck, token gates,
three provider-free browser task-creation cases, and Runner
conformance/replay checks. Its complete CI passed (55 successful checks,
one neutral and four skipped), while Apex returned 2/5 with a
child-delivery finding addressed below.
- The local full-suite attempt again failed the unchanged Git streaming
test (360-second timeout) and was stopped. The concurrent local Rust
attempt failed four unchanged Codex process/deadline tests; all four
passed serially without code changes in 7.29 seconds after removing the
competing test load. These failed commands are retained and are not
reported as full-suite passes; the fresh Linux CI runs are tracked
separately.
- The previous head `907bdb2a2778c7ffeb4a662a91460c9d1ddfc9c5` earned
Apex 5/5 with zero comments after fixing all three findings: per-user
install cache, stale release-pack rejection, and public Linux smoke
account/home handling. Its real built installer passed from read-only
public packages on macOS ARM64 and Linux x64. All 137 release-registry
checks and 64 ACPX package contracts passed. That review does not cover
this mainline reconciliation.
- Prior `beadd3654` passed the full CI matrix; its one unchanged chat
test failure and successful single retry remain in the [CI
history](https://github.com/paperclipai/paperclip/actions/runs/37521449327).
Historical results below remain attributed to their original builds.

- Fixture follow-up `dd59d7e82b103a88b7cbd7d2c38b612c0fbbff7a` removes
provider-specific model choices from generic offline ACPX tests. The
fake sidecar preserves the model and session identity selected at open
through suspension. Affected verification passed: 106 Rust tests and 73
TypeScript tests. This commit changes test code only; the
production-code checks below retain their recorded identities. Its CI
and Greptile review later passed; those results belong to that
historical head.
- Model-selection cleanup `9a070808b48960a41fdfd369ae0636b95af82459`:
252 focused Runner tests passed (six platform skips), covering all six
ACPX agents, native model acknowledgement, rejected selections,
installation integrity and recovery identity. The merged branch passed
recursive typecheck, full build, token gates, server admission (19
tests), and the Product E2E catalog (45 tests). The acceptance catalog
passed all four tests. The full Rust suite passed: 643 tests, 2 ignored.
It verifies sidecar acknowledgement of unlisted models and rejection of
model mismatches. The final commits only update Rust tests; production
sources match the verified build at
`65ec3279ac50185e3cda109b5cfd9b4f56105de0`. No new paid provider calls
were made.
- The merge preserves both Cursor and the new mainline public-MCP
fixture cases. Auto-merge remains disabled; the latest follow-up status
is recorded above. The local `pnpm test:run` attempt hit the unchanged
Git streaming test's 300-second timeout and was interrupted before
merging mainline. The broad Runner attempt found obsolete single-model
assertions plus three macOS fixture-path failures caused by a
`/private/tmp` override. The assertions are corrected; affected
TypeScript checks passed with the standard macOS temporary directory,
and the complete Rust suite passed. Neither interrupted command is a
full-suite pass.
- Earlier declaration-cleanup head `6f4a5e9e2` passed recursive
typecheck, build, Rust and focused tests. Its CI later exposed a test
expecting duplicated Grok digest literals. The current source fixes that
assertion to compare launcher bytes with the shared manifest. Historical
successes and failed attempts are retained; no new live provider
qualification is claimed.
- Previous head `e75fde6098b0ddd8cec765bfb6ecaeecb88a26a6` passed
complete CI (56 successful checks, one neutral, four skipped) and
Greptile 5/5. [Historical complete
CI](https://github.com/paperclipai/paperclip/actions/runs/37489112305).
Those results are not claimed for the cleanup head.
- Frozen live application: `d7b696f9b8f79095233e9e3d56d23e6a6018dd48`.
Public package version: `0.0.0-cursor-verify.3d0c9b7761c6`. The
declaration cleanup preserves release pins and does not relabel that
tested artifact as a build of the new source. Mainline through
`e34abee670` was reconciled while preserving accepted-plan waits,
provider-capacity handling, and both Cursor and public-MCP fixtures.
- Clean normal installation, explicit Cursor setup and daemon resolution
passed on macOS ARM64, macOS x64 under Rosetta, and Linux x64. npm
lifecycle hooks ran without silently downloading Cursor.
- Historical v11 live matrix: **18/18 passed with cleanup** (nine local,
nine Daytona) after the generic mode and lifecycle cleanup. The campaign
has 23 attempts; all five failures and their diagnoses remain recorded.
Exact case identities, hashes and limits are in the readiness report.
All provider calls are real, use the explicit Luna model and
company-bound credentials, and run without qualification or
runtime-asset overrides.
- The immutable Daytona image is
`ghcr.io/paperclipai/paperclip-daytona-runner@sha256:d6259b6bba094702c13fc2283bd85550849c1c53145b656fb2746778f9fa1747`.
The public Daytona plugin is installed independently and its version is
checked.
- Recursive typecheck, full build, token gates and Runner
contract/conformance/replay checks passed on the frozen application. Its
complete Linux CI suite passed. The duplicate local full-suite command
was incomplete after timing failures; affected repeats passed, but that
command is not reported as a clean pass.
- Qualification fixtures passed typecheck, 1,675 Vitest tests (one
skip), 128 Node checks, three provider-free browser tests, and 150
focused lifecycle tests after the final diagnostic correction. The
affected legacy Cursor command file also passed all five tests after
removing its shorter 10-second override; it now inherits the suite’s
standard 15-second timeout. Greptile is 5/5 on `e75fde609` with no
unresolved review threads. CI results above are recorded separately from
historical build results.

## Risks

- Cursor v14 includes the updated ACPX dependency patch and release
identity. The v11 live matrix and image below remain historical
evidence. They do not certify new v14 package/image artifacts.

- ACPX accepts models beyond the qualification fixtures. Availability
and entitlement depend on the provider. Successful configuration is not
a claim of live qualification for every model.
- Shared mode is an opaque identifier. Provider adapters own its
meaning. Incompatible historical sessions remain fenced; exact committed
plan waits and task history remain inspectable.
- Native AskQuestion is excluded. Paperclip semantic questions are
supported. Authoritative per-run dollar accounting is unavailable;
partial counters remain diagnostics and unknown cost is not zero.
- Image input, detailed native diffs, deeper child transcripts and
native plan-file export remain follow-ups.
- macOS x64 has clean-install and daemon-startup proof under Rosetta,
not a separate live campaign on Intel hardware.
- Release only the tested package/image combination. Merging this PR
does not publish npm packages or deploy that image. Later builds need
their own release verification. Rollback disables new Cursor admission
while preserving records and recovery inspection.
- A model can fail an exact instruction: one cancelled-plan attempt
returned the wrong summary marker despite correct cancellation. The
unchanged repeat passed; both results remain in the report.

> ROADMAP.md was checked. This completes existing native Runner/Cursor
work; it does not add an independent core feature proposal.

## Model Used

OpenAI Codex, GPT-6. The exact serving variant and context window are
not exposed in this session. The agent used reasoning, repository
inspection, code execution, protocol tests and browser-backed Product
E2E tools. Cursor acceptance uses the explicit
`gpt-5.6-luna[context=272k,reasoning=medium,fast=false]` model. That is
the evaluated provider model.

Paperclip Native Runner

This package is the standalone development boundary for Paperclip's native runner protocol, process supervision, durable transport, provider drivers, and normalized session backends. Rust owns the production runner under runner/; TypeScript provides the control-plane reference, browser SDK, scenario tools, and conformance oracle.

The package includes one coherent set of capabilities: PRP v1 validation and replay, a supervised local runner with a scripted fake harness, durable WebSocket delivery and recovery, qualified Codex, OpenCode, ACPX, Claude Managed, and AWS AgentCore drivers, live session and issue-thread surfaces, a public browser/React SDK, a standalone adapter demo, and a deterministic mock control plane. None of these surfaces imports or starts Paperclip's server, UI, CLI, or production database.

Connection continuations inspect the harness descriptor's optional toolRefreshOnResume capability. Native Codex, Claude Managed Agents, AgentCore, OpenCode, and qualified Claude/Codex/Grok ACPX profiles expose it; unqualified harnesses leave it false or absent. Changing tools can replace a provider process while retaining the provider conversation. Company, agent, task, workspace, model, instruction, and skill compatibility still gate recovery. An MCP-only assignment change can resume only when the selected harness explicitly supports refreshing tools.

When recovery needs a fresh conversation, the server supplies a deterministic handoff through a lazy history loader at the fresh attempt boundary. It includes the original request, recent messages, resolved interaction summaries, agent replies, and document excerpts, with source identities and retrieval instructions. Reads and excerpts are bounded; the handoff has a 24,000-byte ceiling and explicit truncation/omission markers. Conversation reset boundaries, deleted messages, source quarantine, and secret redaction apply before model submission. Successful recovery does not fetch or replay the handoff. Legacy adapters advertise supportsToolRefreshOnResume for their selected harness: Claude and Codex CLI/ACP, Grok CLI, Gemini/Kimi CLI/ACP, and Cursor/OpenCode/Pi CLI. CLI adapters using environment tool delivery start each invocation with current endpoints and credentials, including resumed turns. ACP reloads current MCP bindings, including run-scoped credentials, while preserving the conversation; an unqualified/custom harness retains its restart fence. Legacy fresh attempts receive the same bounded handoff, including resume-failure fallbacks. Provider authentication repairs retain their existing fresh-session recovery behavior.

ACPX release declarations

acpx-profiles.json owns the package versions, command/profile digests, and required execution policies used by TypeScript and Rust. It contains no models. After changing it, run pnpm --filter @paperclipai/paperclip-runner generate:acpx-profiles. Normal build and typecheck reject stale generated declarations. Generation also checks installed dependency pins and agreement with Cursor's distribution manifest and immutable release attestation (cursor-contract.json). Cursor's per-platform closure pins are generated from cursor-distributions.json.

Every ACPX harness accepts an explicit caller-selected model without a Paperclip model allowlist. The adapter sends that ID unchanged and verifies the provider's effective model before prompting. An incomplete discovery catalog does not block selection; a provider rejection or mismatch fails without choosing a fallback. Qualification model selections live in test catalogs, separately from optional product defaults. The legacy resolved snapshot field qualificationModel contains the caller's selected model; its serialized name preserves recovery identities. Historical profile fixtures remain immutable evidence, not release declarations. The bundled ACPX package tests exercise unlisted model selection, rejection, exact acknowledgement, and replay on a loaded connection. Catalog membership and Cursor model-alias expansion do not determine the selected model. Provider activity adapters own native tool identities, evidence, and diagnostic usage projection; the shared driver and sidecar consume those hooks.

Public package surfaces

  • @paperclipai/paperclip-runner — production contracts, clients/backends, PRP validation/replay, canonical catalog/dispatcher, and compatibility check.
  • @paperclipai/paperclip-runner/testing — deterministic mocks plus PRP and semantic conformance kits. Tests and external conformance consumers import this explicitly.
  • @paperclipai/paperclip-runner/evals — versioned native-attempt metadata, fail-closed package/binary compatibility checks, and explicit runnerd artifact resolution for eval consumers.

The package root has no mock or scenario exports. Generic credential-free matrix orchestration lives in the workspace-private @paperclipai/paperclip-eval-kernel; scenario content and provider-backed eval campaigns remain outside the runtime package. See ADR 0001.

The two conformance surfaces intentionally prove different contracts. The existing runControlPlanePortConformance suite checks narrow PRP run/event persistence. CAPABILITY_HIGH_RISK_SEMANTIC_VECTORS and runSemanticConformanceKit compare normalized tool authorization, state, effects, audit, retries, conflicts, redaction, continuation, and terminal decisions. The production adapter stays App-owned and invokes Paperclip's real route/service authorities; it does not copy those rules into this package.

Quick start

Native provider debug-trace correlation uses an incremental index owned by its transport. Pending event lookups read only newly appended bytes, with a 1 MiB read budget per lookup; they retry until the observed suffix is indexed. Partial records remain pending, and trace replacement or truncation invalidates the index. Closing a transport clears its index. Other active transports cannot evict its progress. Records over 64 KiB are skipped by the correlation index without buffering or parsing their full contents; the original trace file retains them. Do not restore a full synchronous trace scan for each pending event: it blocks event delivery and can leave the board showing an active run after the provider turn has already ended.

The package also builds paperclip-runner-acpx-sidecar. This bounded v2 stdin/stdout bridge admits the pinned Claude, Codex, Grok and Cursor ACPX profiles. It validates the exact model, session identity, tool catalog, structured input, and terminal settlement at the process boundary. Copilot and Pi remain gated. Verified distributions are build-owned; no provider accepts an arbitrary executable. See the rich ACP capability report.

Install Cursor explicitly with paperclipai runtime setup cursor; npm installation does not download it. Run setup as the OS user that runs Paperclip (the service account for a managed service). Setup writes to that account's ~/.paperclip/runtimes/cursor/<platform>-<arch>/<closure-sha256>, so a system-wide npm installation can remain read-only. Isolated provider HOME/XDG settings do not redirect this cache. Container images continue to use their packaged assets. Configure a company secret binding for CURSOR_API_KEY or CURSOR_AUTH_TOKEN, select Cursor in the Runner configuration, and select an exact model ID. Agent is the default; Plan and Ask are explicit modes. Paperclip semantic questions are supported. Native AskQuestion and authoritative per-run dollar usage are unavailable. Accepting a native plan ends the planning run successfully while the task waits for the next instruction. See the Cursor release report.

A release includes all three platform daemons and the Linux provider-pack identity from its matching Daytona image. Run stage:release-binaries with a manifest that binds each daemon path and SHA-256, plus remoteProviderPack: {path, sha256} for the actual image's provider-pack.json. Assemble these assets after the normal build and include them in the server's vendored Runner output before npm packing. Assembly requires the provider pack's source revision to match sourceRevision and its ACPX profiles and Cursor distribution to match the current source pins. An independently rehashed older pack is rejected. Ordinary remote Cursor startup uses the packaged Linux daemon and verifies every image asset against that manifest. A mismatched image fails before the provider starts; install the matching package and image together.

Remote Codex sessions relay assigned app tools through the server's configured gateway. Small catalogs are sent directly. When a catalog would exceed the runner's 256-operation or 768 KiB contract limit, the server exposes paperclip_search_assigned_tools and paperclip_call_assigned_tool instead. Search returns bounded pages of names, descriptions, and input schemas. Each page intersects the session's pinned assignments with current gateway grants. An individual schema that exceeds a page returns an inputSchemaRef. The same search tool retrieves that schema in chunks via schemaTool and schemaOffset; discovery can continue past the large tool. Calls retain task ownership, work-mode restrictions, gateway authorization, approvals, and audit. Core task tools and the runner's completion tools keep their reserved space; no assigned tools are silently removed to fit the limit.

Native Claude skill assignments travel in the runtime-context snapshot through runnerd to the ACPX sidecar. After acquiring the provider lifetime lease, the host materializes the assigned bundles under the isolated Claude home's skills/ directory before launch. Reopening a provider refreshes that snapshot; project and ambient host settings remain excluded. This path is separate from the legacy claude_local adapter's remote skill staging.

The isolated Claude settings pin both model and availableModels to the user's requested ID. This keeps ACP from replacing an exact ID with a picker alias during selection and verification. Users can keep selecting models from the normal Claude catalog or entering custom IDs; unavailable models still fail at the provider rather than silently falling back.

ACPX Claude defaults to approve-all, shown as Full auto (approve all). OpenCode defaults to allow; native Codex defaults to never (no approval pauses). These defaults cover all assigned tools and connections, including provider-native operations. Full auto is resolved consistently for agent creation, adapter conversion, direct driver launches, and fresh/resumed turns. Explicitly stored restrictive modes still apply.

The runner's authenticated bridge and controller still enforce company access, action claims, task modes, and governed approvals. Provider permission defaults do not change workspace isolation or grant credentials or connection access. approve-paperclip remains an optional narrower mode for assigned planning and task tools; approve-reads allows assigned reads; deny-all rejects requests. None of these restrictive modes is the default.

Restrictive profiles route supported permission decisions through durable runtime requests and the existing task interaction controls. Requests are persisted before presentation; answers are checked against the offered decisions and acknowledged by the sidecar before settlement. Unknown, stale and duplicate responses fail. Missing provider decision support remains a blocked disposition, not implicit approval. Company access checks still run for each Paperclip tool. Provider death expires pending promises; approvals are never replayed into a replacement process.

Automatic Paperclip/read allowances currently require the Claude SDK dispatch boundary. Grok preserves these restricted settings, but its ACP requests lack independently bound tool authority. Those operations require a supported operator permission decision; a missing interactive responder stops with approval_required. An explicitly selected approve-all policy permits unattended Grok work in an assigned sandbox. Paperclip authorization and governed approvals still apply.

Runnerd selects only qualified provider profiles. Claude Managed and AWS AgentCore receive immutable company-profile snapshots with explicit retention, spend, and invocation limits. No provider process receives a Paperclip API credential or unrestricted server environment.

Claude Managed resolves its API key from the company secret bound to the selected profile. AWS AgentCore uses workload identity only; long-lived static AWS access keys are intentionally removed from the runner environment.

The Rust core includes a bounded client for the sidecar protocol. It enforces request identity, event order, frame and queue limits, timeouts, redacted diagnostics, and process-group cleanup. Runnerd selects this package-local transport only through an exact qualified provider descriptor.

Before a later provider adapter consumes a valid sidecar event, the Rust core also requires its optional or mandatory run and turn scope to match the active execution. Process and diagnostic events can remain global. All operational, tool, input, permission, and terminal events require the exact active binding.

A package-local payload boundary decodes events only after that scope check. It validates control identities, terminal status, question sets, and the admitted runtime event types and bounded fields. It redacts diagnostic and retained event values again before they can enter provider state. Authoritative semantic tool arguments are validated for transport bounds and forwarded unchanged, including credential-bearing document and instruction content. The provider harness owns credential policy; redaction of logs and audit previews must not reject or rewrite execution arguments. Diagnostic detection requires explicit credential fields/assignments or recognizable key, Bearer, JWT, or PEM formats, not ordinary prose such as "credential handling" or dotted filenames.

Human question tools accept one complete payload.questionSet for text and choice questions. The control plane generates legacy questions entries with stable free-text option IDs. Legacy callers remain supported. Calls that supply both forms must describe the same complete form; partial forms remain invalid. The native recovery bridge uses the same projection for answer delivery.

The server validates canonical answer constraints before persistence. Regex matching runs in isolated workers with a one-second deadline and at most four active workers. A timeout or capacity error leaves the question pending. The ordinary and native answer paths both await this validation before persistence. Saved native answer delivery does not repeat regex matching.

Validated ACPX runtime events normalize into the same provider-neutral activity families as the direct Codex transport. Reasoning contents stay private. Tool targets are resolved within the workspace under the provider host's path semantics and receive a versioned sidecar boundary marker before becoming bounded, display-only PRP safe paths. Raw or unmarked provider locations fail closed. URI-scheme and Windows drive-shaped values require a separate sidecar attestation backed by an existing in-workspace entry or, for a not-yet-created edit target, an existing in-workspace parent. This preserves real POSIX colon filenames without treating arbitrary URI text as a path. Windows separators are canonicalized, and consumers must not reinterpret the display value as file-access authority. Operational semantic-result and terminal events remain reserved for the stateful adapter rather than being duplicated.

The ACPX provider reducer preserves that order while it tracks one active turn, bounded assistant text, semantic results, and pending tool or input correlations. Terminal events flush the final assistant message first and clear unresolved turn-scoped requests.

The package-local session bootstrap starts the bounded sidecar transport, verifies the qualified capability handshake and effective model, opens one identity-bound session, and confirms its run attachment. Any failed bootstrap terminates the process; session shutdown preserves persistent provider state. The session can then start one immutable-workspace turn, request interruption, and reduce polled events through the scope-first state boundary. A mismatched command acknowledgement or invalid event terminates the session fail closed. Polled semantic calls pass through the run-scoped authorized tool bridge before they can be returned to a caller. Before a follow-up turn releases settled tool receipts, runner-core suspends and reaps the idle sidecar/provider generation, then resumes the same verified persistent identity in a fresh generation. This prevents a late session-lifetime MCP callback from inheriting the next turn's event authority.

The Rust question-response validator checks the versioned response envelope against the exact persisted question IDs, answer modes, options, required answers, custom-answer policy, and text constraints before provider delivery. Tool results and structured question responses then use two-phase resolution: validate retained identity and schema, require the exact sidecar acknowledgement, and only then clear pending local state. Codex permission requests violate its pinned sidecar policy and terminate the session fail closed. Safe suspension is available only with no active turn or pending request. The sidecar must return the exact persistent session identity before runnerd terminates the local process. Already validated ACPX reducer events project into provider-neutral durable events only with an exact run, session, turn, and item binding. Raw sidecar envelopes and permission requests are not admitted at this boundary. A safely suspended session can be recorded as a bounded private checkpoint. The checkpoint binds the exact provider identity, run, catalog revision, and catalog digest and is replaced atomically before a later recovery attempt. Recovery releases the stored identity only after those bindings match the prospective session configuration exactly.

Run the complete contract gate with:

pnpm install --filter @paperclipai/paperclip-runner --lockfile=false --offline --ignore-scripts --dev
pnpm --filter @paperclipai/paperclip-runner verify

The verification command requires a stable Rust toolchain with cargo on PATH, in addition to Node.js 24.11+ and pnpm 9+.

Minimal Debian/Ubuntu hosts without root access can extract the required Playwright browser libraries into a user-owned cache and run the same acceptance sequence with:

pnpm --filter @paperclipai/paperclip-runner verify:rootless

The tracer's final line is stable:

{
  "schemaVersion": "paperclip.runner.conformance.output.v1",
  "runIdentity": {
    "runId": "run_conformance_0001",
    "sessionId": "session_conformance_0001"
  },
  "result": {
    "status": "succeeded",
    "summary": "Standalone Conformance fixture accepted."
  }
}

Run only the tracer with:

pnpm --filter @paperclipai/paperclip-runner trace:conformance

Replay the Replay happy path, run a Local session, or open the browser devtool:

pnpm --filter @paperclipai/paperclip-runner replay:fixture
pnpm --filter @paperclipai/paperclip-runner trace:local-runner -- --scenario happy-path
pnpm --filter @paperclipai/paperclip-runner trace:codex
pnpm --filter @paperclipai/paperclip-runner demo:live-console -- --host 127.0.0.1 --port 4174

# Live console: chat with a live session in the browser.
pnpm --filter @paperclipai/paperclip-runner console:live-console
pnpm --filter @paperclipai/paperclip-runner browser:dev --host 127.0.0.1 --port 4179

# SDK: open the public-SDK reference console and mini consumer.
pnpm --filter @paperclipai/paperclip-runner console:sdk

# Standalone: run the standalone legacy/native/kill-switch tracer and page.
pnpm --filter @paperclipai/paperclip-runner trace:standalone
pnpm --filter @paperclipai/paperclip-runner trace:standalone -- --feature-flag enabled
pnpm --filter @paperclipai/paperclip-runner trace:standalone -- --feature-flag enabled --kill-switch enabled
pnpm --filter @paperclipai/paperclip-runner demo:standalone

Live console provider-backed routes are loopback-only and reject wildcard/LAN binds. Browser mutations require same-origin Fetch Metadata, matching Origin, and JSON content; see the protocol-server tutorial for direct curl examples.

Direct live protocol qualification

The canonical direct live protocol suite lives in the separate paperclip-evals repository under evals/paperclip-runner/. Its live-mini.json roster is the complete 35-case Codex qualification lane. Build this package's TypeScript output, release paperclip-runnerd, package tarball, and dist-issue-thread viewer, then use the roster runner documented in that repository. The package ships the required orchestration entry point as paperclip-runner-eval-session (dist/cli/eval-session.js). Evalbook owns the consistent HTML matrix and read-only attempt drill-down pages.

The hosted full-campaign workflow, parallel matrix, credential boundaries, canonical report merge, and versioned S3 index are documented in docs/runner-protocol-live-evals.md.

This direct protocol qualification is separate from the stress-derived Runner workflow schedule below and from the full-stack browser model E2E suite.

Stress-derived workflow, chaos, and AWS AgentCore operations

The deterministic workflow scorer and the chaos schedule do not require provider credentials:

pnpm --filter @paperclipai/paperclip-runner test:runner-workflow-evals
pnpm --filter @paperclipai/paperclip-runner report:runner-chaos-evals

report:runner-live-evals is a paid, provider-backed command. Native Codex requires OPENAI_API_KEY; ACPX Claude requires ANTHROPIC_API_KEY; OpenCode candidates require OPENROUTER_API_KEY. The live matrix remains qualified-only and does not persist credential values. Candidate qualification uses eval-session --candidate-profile <pi|cursor|copilot> with an explicit model and a separately materialized pinned candidate pack. This option is a constructor-bound diagnostic opt-in; session JSON cannot enable a candidate. Missing credentials or unverifiable spend block paid qualification. Set PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD to a positive finite number to bound additional scheduling after the observed campaign total reaches that value:

PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD=12 \
  PAPERCLIP_EVALS_ROOT=/path/to/paperclip-evals \
  pnpm --filter @paperclipai/paperclip-runner report:runner-live-evals

# Run two scheduled native Codex executions only.
PAPERCLIP_EVALS_ROOT=/path/to/paperclip-evals \
  pnpm --filter @paperclipai/paperclip-runner report:runner-live-evals -- \
  --candidate codex-luna --limit 2

GitHub-hosted live campaigns additionally require the default branch, an allowlisted numeric actor ID, the protected runner-e2e-paid environment, and an explicit repository variable before scheduled runs are enabled. Manual dispatches accept the same candidate, case, and execution-limit selectors. The paid job uses the reviewed RunsOn Fleet label when RUNNER_E2E_AWS_ENABLED=true and otherwise stays on ubuntu-latest. Uploaded reports contain redacted observations and trace digests, not raw provider frames, prompts, credentials, tool arguments, or hidden reasoning.

The AgentCore proof-of-concept uses an AWS CLI v2 profile to provision a dedicated invocation role and scoped resources. Its local mode-0600 metadata file contains no access keys; probes assume short-lived STS credentials and clear them after use. Validate locally, provision or inspect the stack, run the bounded lab/smoke, and tear it down explicitly with:

pnpm --filter @paperclipai/paperclip-runner test:aws-agentcore-provisioning
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision -- --dry-run
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:probe
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:lab
pnpm --filter @paperclipai/paperclip-runner smoke:capability:aws-agentcore
pnpm --filter @paperclipai/paperclip-runner aws-agentcore:destroy -- --yes

To admit the hosted direct-eval workflow, provision with the account-local GitHub Actions OIDC provider and keep the default exact repository and protected environment binding:

pnpm --filter @paperclipai/paperclip-runner aws-agentcore:provision -- \
  --aws-profile paperclip-dev \
  --github-oidc-provider-arn arn:aws:iam::<account-id>:oidc-provider/token.actions.githubusercontent.com

This adds only repo:paperclipai/paperclip:environment:runner-e2e-paid as a web-identity subject on the scoped invocation role. The generated nonsecret profile records that role as both the local invocation role and the hosted execution role.

Provisioning can incur Bedrock, AgentCore Runtime/Memory, storage, and private networking charges. Provisioning refuses to modify a colliding stack unless its Paperclip ownership tags and template description match. A verified ROLLBACK_COMPLETE stack still requires --replace-failed-stack plus an interactive confirmation (or --yes) before it can be deleted and recreated. Destruction requires --yes and refuses to remove a stack with an active recorded lab unless --force is also supplied.

Navigate

Codex adds the package-local real-model reference driver, Live console adds the package-local browser console, and SDK extracts a reusable public SDK plus two standalone consumers. Runtime production Paperclip integration remains deferred; the App-owned production conformance adapter is test-only.

The SDK reference console opens in direct chat mode. Enter a normal prompt, then open the protocol inspector to review events and reducer state. Expand a Terminal row and its nested Debug details disclosure to inspect every canonical event retained for that command. The header marker 🖇️ v0.1.2 identifies the current console iteration.

create_task accepts an optional initial status of backlog or todo. Use backlog when the user wants a saved task or plan without execution: assignment and the initial plan are committed without scheduling a wake, even when dependencies are already complete. Omitting status preserves immediate delegation (todo, or blocked for unresolved dependencies).
