## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Native execution keeps provider state and a durable controller journal. > - A completed process can stop before the next run attaches. > - The current run must own recovery of that exact source. > - An old controller must lose permission to change the consumed source journal. > - This pull request adds explicit source admission and protected task dispatch. > - The benefit is a narrow recovery boundary that preserves the original successful result. ## Linked Issues or Issue Description Native prerequisites #19132 and #19153 are merged into master. This PR targets master and updates the TypeScript Runner driver contract alongside Core and SDK admission. This change adds the SDK and Core admission boundary. Executor selection and fresh source preparation are a separate change. Related #17916 supplies the workspace export holds preserved here. ## What Changed - Plugins advertise `codexSourceRecoveryVersion: 1` for Codex App Server and `acpxSourceRecoveryVersion: 1` for ACPX. Hosts can qualify either, both, or neither. Core selects the matching field, because a stopped-source check for one provider cannot establish the other provider’s recovery guarantees. ACPX orchestration is tracked separately in #19196. Use the existing exact source identity and `resumeFrom` under the authenticated current run. No public recovery mode is added. Require the claimed source, current account and prepared launch at protected dispatch. - Keep the first source binding pinned on the consumer lease, including after uncertain dispatch. A newly acquired coordinator can refresh only the same source. - Claim one stopped successful source under the current run's acquired native lease. Store the token-free consumer reference in existing lease metadata. Preserve the source status and result. - Check the exact six source identity fields, encrypted journal header, company, task, agent, environment, driver, workspace, account selection, and current coordinator generation. Keep workspace export and legacy settlement holds. - Serialize claims and checkpoint writers in the same coordinator lock order. Reject stale source writes after consumption. Check the current consumer before recovered source writes. - Check source admission before and after protected worker dispatch. Keep the request and lease owned by the current run while the native identity remains the source. - Allow the same owner to prepare B after a fresh source submission, using the exact consumed-source proof instead of a generic warm-reuse flag. Recheck that proof after dispatch. - Preserve ordinary cached adoption and repeated preparation after launch. The current authenticated owner can differ from the adopted PRP identity without requesting a new source launch. Keep ordinary suspended recovery and live task attachment checks. Extract the shared source resolver to avoid a module cycle, and make ordinary selection honor the same durable source consumer. ## Verification - Current head `cac9cf188a` includes merged #19300 and the symmetric capabilities introduced in `b7e25a64b4`. The task-owner and warm-rebind fixtures now identify their physical task. All 29 SDK schema cases, 95 Core ownership and source-admission cases, 25 native Codex and ACPX recovery cases, and the binary metadata check passed on this head. The SDK and Runner builds and server typecheck passed. Both native providers reject the other provider’s capability. GitHub CI is green and [standard Greptile scored this commit 5/5](https://github.com/paperclipai/paperclip/pull/19134#issuecomment-6645574114) with no open threads. - Previous head `bda49271a4ae362a15baf3fe6d6d297e25fd2000` is directly based on master after #19132 and #19153 landed. [GitHub workflow 42072192023](https://github.com/paperclipai/paperclip/actions/runs/42072192023) passed on its first attempt. All check runs completed successfully or as intentional workflow skips; Snyk passed. Standard Greptile scored this exact head 5/5. That review had no unresolved findings. - Runner and SDK TypeScript builds and server typecheck passed. The focused SDK, task-owner, task-runtime, PostgreSQL source and authority suites passed all 161 cases. The production transport-factory getter regression and 14 native-lane selection checks also passed. - The Linux native lane executed the new ordinary warm A→B process case. It kept one Runner/provider process and completed two turns on the same thread. The eager-getter mutation fails with `native_runner_source_attachment_pending`; preserving the live getter passes. The production factory test changes the current owner after transport creation and checks that same options object. - PostgreSQL cases cover both concurrent source-writer/claim orders, exact source submission under the current caller, source-switch denial after uncertain dispatch, same-source coordinator refresh, stale same-boot generation, corrupted journal headers, competing consumers, account changes and export holds. - The protected dispatch sequence submits A, prepares B and retries B preparation. It rejects undispatched sources, changed accounts and foreign target bindings. Source status and accepted result remain unchanged. - Ordinary adopted A preparation under current B, repeated ordinary preparation after launch and ordinary suspended continuation retain their existing path. Absent or false claims preserve ordinary identity denial; malformed claims fail closed. - Earlier development attempts exposed ordinary preparation regressions and the live-getter omission; the final regressions cover those fixes. The first embedded PostgreSQL attempt needed missing library aliases repaired in ignored dependencies. Those attempts are not passing evidence. - Historical, superseded CI heads had unchanged UI fake-timer and Playwright health-response-lifetime failures. Their isolated cases and scoped retries passed. The response-lifetime cause remains unproven. No UI/test timeout was changed. The final rebased-head workflow above passed without a retry. - Whitespace and added-line secret/PII scans passed. Full workspace checks ran on GitHub. No live vendor probe or deployment was performed. ## Risks - Any driver that used the earlier Codex TypeScript option must use `codexSourceRecoveryVersion`. The new plugin description rejects the generic spelling. The Launcher’s existing Codex-specific HTTP header can map to this property when the plugin adopts the new SDK. The change requires no journal migration or ROM change. - This is an inactive admission foundation. Executor orchestration is separate in #19157. Native restore integrity and provider stopped-source/account validation must be present before executor activation. The native prerequisite uses ordinary recovery followed by attachment. The composed executor proofs are in #19157. - The source claim is durable. A later controller must recover the same consumer or keep the hold. It cannot select another source after an ambiguous launch. - Admission adds bounded database checks around protected startup calls. Busy issue locks fail closed; other lock waits have a one-second bound. - No migration, snapshot format, proactive receipt, recurring worker, or deployment is included. Full workspace checks and platform coverage run in CI. These tests do not prove vendor history durability or a hosted rollout. ## Model Used OpenAI GPT-6.1 Sol (`gpt-6.1-sol`), high reasoning, through Codex with repository tools and code execution.
