## Thinking Path > - Paperclip manages AI agents and owns their task authority. > - Remote native agents can keep working while their controller restarts. > - The controller must authenticate the same runner and verify its provider files before recovery. > - The current path compares a retained provider pack with the new controller release. A release change can reject intact files. > - The new controller binary digest can also reject the original daemon during PRP authentication. > - This PR records the admitted release authority in private controller state and uses it for exact process reattachment. ## Linked Issues or Issue Description **What happened?** A remote Claude session started and used tools. After controller shutdown, recovery failed with `runner_remote_provider_artifact_incompatible`. The transport combined stderr into stdout, so the error omitted the verifier reason. The historical rejected manifest is unavailable. This PR reproduces controller release drift as a cause; it does not claim that the historical mismatch is proven. Reaching pack verification implies the earlier exact-process/controller-identity checks passed. That supports a preserved-state recovery path but is not a direct inspection of the deployed volume. **Expected behavior** A compatible, unchanged remote runner can reattach after a controller release changes. Full package hashes, exact process scope, protocol capabilities, and authenticated runner identity must still pass. Fresh launches use the current release. **Steps to reproduce** 1. Verify and admit a remote native session with release A. 2. Preserve its runner process and replace the controller with release B. 3. Reattach the original process. The old path compares its pack with B and fails at `manifest mismatch`. 4. With this fix, the controller reads its saved A authority and verifies all A hashes. Changed files still fail. **Paperclip version or commit** Reproduced from master `470cb34c0e42cb9d0b232d0bcf5d45cc7b0a81ca`; rebased onto `a3675ddcdf`. **Deployment mode** Native remote runner on a Daytona-backed Paperclip Computer. Local acceptance uses isolated Linux containers and actual packaged artifacts. Related work: #17361 and #17448 handle runner upgrade and qualification permissions. #17097 and #17439 add durable controller checkpoints and server adoption. That stack can skip remote artifact preparation with a saved checkpoint. This PR fixes the current file-backed path and retains full provider-pack verification; it has no checkpoint schema or empty-disk controller recovery. ## What Changed - Save the complete verified pack manifest and authenticated runner version/digest after successful session admission. - Bind the receipt to company, agent, workspace, session, runner, environment lease, remote directory, and provider descriptor. Keep it outside guest backup directories. - Reuse the saved authority for exact reattachment. Keep current release selection for fresh launches and explicit session replacement. - Fail closed for mismatched or corrupt receipts. Historical sessions without a receipt retain the current release integrity gate. - Report bounded, redacted verifier output from both transport streams. Warn on receipt write failure while returning the already admitted session to its owner. - Add scope, persistence, replacement, storage failure, and backend wiring regressions. Update recovery documentation and the feature map. ## Verification - Test-first red: the original selection chose release B instead of A after controller recreation. The new receipt regression passes. A separate red test showed the missing stdout diagnostic; it passes after the diagnostic fix. - Authority and diagnostic suites: 49 tests pass. Backend pack, process adoption, and harness persistence selection: 47 tests pass. - Actual Linux provider image: complete A manifest/artifact verification passed; controller source-revision drift failed on the old path; saved A authority passed; a modified ACPX sidecar failed its SHA-256 check. - Actual native Linux runner: authenticated a session, detached the controller, changed the controller manifest and binary, then authenticated the original PID and provider session with saved authority. There were zero duplicate spawns, zero new provider turns, no stop/suspend, and the workspace file remained. This probe used the real runner with a deterministic Codex fixture; it is separate from the real ACPX package integrity proof. - Full workspace typecheck and build passed. The full native executor suite first hit host PostgreSQL semaphore exhaustion. The complete changed files then passed 864/864 tests with separate real PostgreSQL databases in a disposable Linux container. The temporary local fixture changed only database provisioning and used normal repository migrations. Current-head CI also passed the full required test, Runner, browser, typecheck, and build lanes. - `node scripts/check-maps.mjs` and `git diff --check` passed. These structural checks do not prove live recovery. - Current head `48fca2ae33d99f7f6d2fe12f431cf76d25185c70`: 55 successful checks, two conditional skips, no pending or failed checks; fresh Greptile 5/5 with zero findings and zero unresolved review threads. Commitperclip quality review passed. - No original task was retried or changed. Existing Daytona access could not resolve the original sandbox or its image; a fresh staging Claude recovery is not claimed. ## Risks This prevents recurrence for sessions admitted with the new receipt. It does not retroactively recover the historical failed run. Saved authority exists only after this change has admitted a session. It cannot repair an ambiguous historical launch or restore a receipt on an empty replacement controller. A stale protocol or modified pack remains a hard failure. Receipt write errors warn without losing the live session handle, but later recovery still needs matching authority. The broader checkpoint stack changes the same server preparation and runner-artifact option and will require a deliberate integration. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository tools, and code execution. The runtime does not expose a more specific model ID or context-window size. ## 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 - [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>
