# 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. ## 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](docs/adr/0001-runner-testing-eval-package-boundaries.md). 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 The package also builds `paperclip-runner-acpx-sidecar`. This bounded v2 stdin/stdout bridge admits the pinned Claude and Codex ACPX profiles. It validates the exact model, session identity, tool catalog, structured input, and terminal settlement at the process boundary. Pi remains unavailable. 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. 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: ```sh 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: ```sh pnpm --filter @paperclipai/paperclip-runner verify:rootless ``` The tracer's final line is stable: ```json { "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: ```sh pnpm --filter @paperclipai/paperclip-runner trace:conformance ``` Replay the Replay happy path, run a Local session, or open the browser devtool: ```sh 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. ## Live, chaos, and AWS AgentCore operations The deterministic workflow scorer and the chaos schedule do not require provider credentials: ```sh 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 and the ACPX Codex profile require `OPENAI_API_KEY`; ACPX Claude requires `ANTHROPIC_API_KEY`; OpenCode candidates require `OPENROUTER_API_KEY`. The live matrix admits no Pi profile and does not persist credential values. Set `PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD` to a positive finite number to bound additional scheduling after the observed campaign total reaches that value: ```sh PAPERCLIP_EVAL_MAX_CAMPAIGN_COST_USD=12 \ pnpm --filter @paperclipai/paperclip-runner report:runner-live-evals ``` 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. 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: ```sh 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 ``` 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. ## Package-owned commands | Command | Purpose | | ------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | `build` | Compile the TypeScript public surface, Rust workspace, and browser devtool. | | `typecheck` | Check TypeScript, Rust, generated schema sources, and browser types. | | `test` | Run Rust/TypeScript fixture, supervisor, fake-driver, live/replay, and boundary tests. | | `check:forbidden-imports` | Reject TypeScript imports and Cargo path dependencies that cross into Paperclip core. | | `check:tracked-imports` | Reject tracked imports and `package.json` entry points that only resolve against untracked files, so a clean checkout of any commit builds. | | `check:numbered-milestones` | Reject numbered construction-milestone names in tracked package paths and source. | | `check:package-boundaries` | Enforce the acyclic runtime/testing/eval dependency and manifest boundary. | | `check:clean-consumers` | Pack the runner and install its root, evals, and testing exports in a clean consumer. | | `test:eval-slice` | Run the credential-free eval bundle, scoring, and behavior/fault slice. | | `test:runner-workflow-evals` | Run the deterministic provider-neutral workflow matrix. | | `report:runner-workflow-evals` | Validate deterministic results and write local reports only when every scoreable result passes. | | `report:runner-live-evals` | Execute the paid forty-execution provider schedule with qualification and campaign-cost guards. | | `report:runner-chaos-evals` | Write the credential-free eight-scenario chaos schedule. | | `test:aws-agentcore-provisioning` | Validate the AgentCore template and wrapper safety contracts without provisioning. | | `aws-agentcore:provision` / `probe` / `lab` / `destroy` | Manage the scoped AgentCore proof-of-concept lifecycle. | | `smoke:capability:aws-agentcore` | Exercise the qualified AgentCore profile through the capability harness. | | `check:conformance-parity` | Require byte-for-byte equivalent Rust and TypeScript tracer output. | | `check:replay-goldens` | Require all reducer snapshots and cross-language summaries to match checked goldens. | | `check:replay-parity` | Run TypeScript and Rust against the same Replay fixture summaries. | | `check:browser-tokens` | Reject component-local visual literals and require the standalone token layer. | | `docs:validate` | Validate local documentation links. | | `trace:conformance` | Run the Rust mock-core tracer, print the stable result, and exit. | | `trace:conformance:typescript` | Run the TypeScript reference tracer directly. | | `replay:fixture` | Validate and reduce a fixture to a final snapshot. | | `trace:local-runner` | Run one native local session through the Rust runner and fake harness. | | `trace:codex` | Run the mock core with a real, local skillless Codex app-server session. | | `demo:live-console` | Start the package-local HTTP/SSE server with server-only Codex authentication. | | `console:live-console` | Start the standalone browser devtool with the Live console on `127.0.0.1:4180`. | | `console:sdk` | Start the public-SDK reference console and mini consumer on `127.0.0.1:4181`. | | `test:sdk` | Run targeted browser-client, reducer-projection, and React component contract tests. | | `test:browser:sdk` | Exercise both consumers with the fake driver, keyboard/a11y checks, reconnect/replay, measurements, and screenshots. | | `record:sdk:codex` | Run both public consumers against a safe real Codex session and capture live screenshots. | | `check:capability-contract` | Verify the generated capability, legacy MCP, and eval traceability contract. | | `check:semantic-contracts` | Verify the provider-neutral semantic tool contract is current. | | `trace:live-runner` | Run the real runnerd/Codex semantic loop against the mock control plane. | | `demo:scenarios` | Start the Capability scenario explorer over the mock control plane on `127.0.0.1:4183`. | | `console:issue-thread` | Start the Paperclip-style issue thread on `127.0.0.1:4184`. | | `test:scenarios` | Run the scenario index, run-artifact, parity, explorer component, and route tests. | | `test:browser:scenarios` | Exercise both the scenario explorer and issue-thread browser contracts. | | `browser:dev` | Start the standalone live/replay browser devtool. | | `test:browser` | Exercise static replay and live scenarios, then capture temporary screenshots under ignored test output. | | `verify` | Run the complete deterministic Conformance through SDK acceptance sequence. | | `verify:rootless` | Extract Debian/Ubuntu browser libraries without root, then run `verify`. | ## Navigate -

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.
