## Thinking Path > - Paperclip manages work for AI agents. > - An environment plugin can own a Runner task. > - The merged launch-preparation contract lets the execution owner build the provider configuration. > - Core still needs a task process owner and a setup test that uses that configuration. > - This PR connects the task API to the Runner process-owner contract. > - Operators can test a plugin environment before Core sends it task work. ## Linked Issues or Issue Description **Subsystem affected** Runner, plugin SDK, and agent environment tests. **Problem or motivation** A task-only environment cannot use the shell-based setup path. Core must verify the Runner hello exchange and process cleanup through dedicated task operations. **Proposed solution** Add a lease-bound task driver and use it for a bounded setup probe. Keep heartbeat admission and task execution in #16978. This PR follows the merged launch-preparation contract in #16997. **Alternatives considered** A provider declaration alone cannot prove that Runner and the provider connect. A shell bridge would give the plugin an unnecessary command interface. ## What Changed - Pass structured Runner launch data to process owners. Support an external connection and explicit detach. - Add typed launch authentication checks and checkpoint operations. Check lease, run, project, and retained-task authority. - Connect launch preparation, PRP, termination proof, and credential handoff to the task driver. Reject local environment overrides during installed-account setup. Pass saved-account identity and credential home directly from Core. - Run a short-lived setup probe through the existing agent environment test API. Require a verified provider hello and cleanup. Keep saved Copilot account checks metadata-only through a dedicated task operation. - Update the Copilot source identity because the shared transport source changed. Keep provider behavior and the earlier identity fixture. ## Verification - CI passes on `f987adec7`: 55 successful checks and 5 expected skips. Standard Greptile and Apex are both 5/5 with no open findings. The branch merges cleanly with current master. - Repository typecheck and build pass after the rebase onto the workspace-provider contract. Server typecheck and build also pass after the final setup fix. - The 110 focused lease, SDK, setup, Copilot, and route cases pass after the rebase. All 14 setup cases pass after the final change. These include a real local Runner with a test provider. The saved-agent model-discovery case also passes. - Apex found that Core's relative workspace marker failed the driver path check, and non-Codex sessions omitted the observed model. Both failures were reproduced and fixed. The probe leaves physical workspace selection to plugin preparation. The transport reads each provider's observed model and exposes it to the driver. All 14 setup cases, 6 transport peer cases, and both existing real Runner/OpenCode cases pass. Runner build and server typecheck pass. - The coverage audit removed two redundant cases, repeated fixture code, and two extra real Runner launches. It kept authorization, credential selection, cancellation, lost replies, termination proof, checkpoint identity, and provider setup checks. - The Copilot source-identity check passes. The added-line secret and PII scan passes. The unmerged v52 attestation was regenerated after the shared transport fix. - CI on `13faeff02` caught one stale Copilot digest assertion after attestation regeneration. The literal now matches the candidate attestation, and all 49 installation cases pass. That CI lane otherwise passed 1,818 cases. - An earlier CI run hit an unchanged UI toast timing test. The separate fix is tracked in #16952. Current CI passes that shard. CI also caught a stale model-discovery assertion in this change; the assertion is fixed. - The local full-suite run was stopped when master changed. The final CI run supplies exact-head full-suite validation. No live Cloud or provider test was run. ## Risks - Native hello tests require a saved Core account or the installed account. Local environment overrides are unsupported for installed-account probes and fail before the provider runs. - A native task provider must declare launch preparation and authentication-check version 1. It must keep the checked configuration fixed through submission. Core rejects providers that cannot make this guarantee. - A lost task reply does not prove process termination. Core retains grants until the provider proves termination and Core saves required state. - This PR does not enable native heartbeat dispatch through plugin environments. Cloud deployment and live provider validation remain separate. ## Model Used OpenAI Codex, GPT-6. The exact model ID and context window are not exposed in this session. Tool use includes code editing, local tests, and the GitHub CLI. ## 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 described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links - [x] My branch name describes the change and contains no internal issue details - [x] I have run focused 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 - [x] All Paperclip CI gates are green - [x] 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: Paperclip <noreply@paperclip.ing>
