From fac07b42ad41cf24ee1d9de6837567607746daf2 Mon Sep 17 00:00:00 2001 From: Dotta <34892728+cryppadotta@users.noreply.github.com> Date: Wed, 9 Sep 2026 11:02:59 -0500 Subject: [PATCH] fix(runner): preserve durable native session authority across recovery (#13092) ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The native runner carries tool results and task output to the control plane. > - A lost connection must not change which run owns a result. > - A session must not become reusable while provider output is still pending. > - This pull request adds strict recovery evidence and bounded drain barriers. > - It preserves current PRP version negotiation and session-goal support. > - The benefit is safer reuse of native sessions after a transport failure. ## Linked Issues or Issue Description Refs #13038. This is the first of two stacked pull requests. It contains the native runtime prerequisites. The second pull request contains the experimental chat-channel integration. It preserves the provider identity and typed terminal-failure contracts in #13074 and the durable recovery work in #13075. **What happened?** Native session failures could leave retained provider events, incomplete tool results, or warm handoff state that was not safe to reuse. A later run could observe output from an earlier authority. **Expected behavior** Recovery must preserve exact run, tool, process, artifact, and lease evidence. Uncertain or corrupt state must fail closed. A successful close must prove that retained provider output is settled. **Steps to reproduce** Run the transport and control-plane regressions. They hold and drop authenticated frames, fail durable writes, and restart fresh controllers and runner processes with retained state. Provider executables are local test fixtures. ## What Changed - Preserve pending provider cleanup and semantic-result evidence across session close and restart. - Add an authenticated warm handoff with exact old and new identities, durable receipts, and completion acknowledgement. - Drain retained provider events under the cumulative acknowledgement fence. - Reject corrupt tool-result contracts without unsafe provider replay or reusable checkpoints. - Keep ordinary PRP v1 sessions and current session-goal behavior. Require negotiated PRP v2 and acknowledged native session evidence before warm authority rotation. - Preserve late semantic inputs and exact durable result receipts until close can prove settlement. - Add transport, crash-window, artifact, checkpoint, and final-output regressions. - Deduplicate resolved execution delivery under the current issue lock. Reuse the exact existing successor after concurrent scans or a lost acknowledgement. Preserve newer operator evidence. - Persist idle provider integrity/capacity failures before process retirement, retain permanent model-rejection classification, and keep external question identifiers out of task instructions. - Expose only the context source on native status events. Keep thin dispatch projections compatible without exposing the complete context. ## Verification - Review-fix revision: 128 runtime-context/native-session tests, five idle-failure/adjacent Rust cases, 24 warm crash-window cases, three startup-notification/close cases, and five attach/backlog cases passed. The security and idle-failure cases were first reproduced failing. - Prior merged revision: runner production build, TypeScript typecheck, complete Rust workspace tests and formatting passed; 272 focused runner tests and two real PostgreSQL regressions passed. - Earlier full runner runs and CI Build failed on missing semantic-result fixture receipts, stale local provider fixture bytes, startup-notification ordering, and a confirmation-loss fixture that could accidentally send its final ACK. Each cause was reproduced and corrected without relaxing production authority or close assertions. These earlier runs are retained as failures, not represented as passing verification. - The first local repository-wide run failed before later phases because the isolated install omitted PostgreSQL's native-library aliases; it also encountered an unrelated occupied-port fixture. Those results are retained, not represented as a passing run. - Exact `335b2ee52709afb3885d4d6ebb2a3ece4b5864d6`: the complete runner suite passed 1,888 tests, with 10 existing skips. The full Rust release workspace passed with serial test scheduling. The unchanged parallel Rust run hit the five-second 300-descendant fixture deadline; that failure is retained. No deadline or assertion was relaxed. - The resolved-execution regression suite passed 57 tests, including concurrent delivery, lost acknowledgement, superseded authority, and newer operator evidence. Plain server typecheck passed. The duplicate-delivery cases were first reproduced failing. - Prior exact `335b2ee52709afb3885d4d6ebb2a3ece4b5864d6` CI passed all required jobs and Greptile reported 5/5. Its local general-server run passed 7,208 tests but failed one responsibility fixture; later phases did not run. The fixture started the next wake while its bounded handoff was active. It also used nonexistent comment IDs, which hid the current stored-message-author identity rule. The updated tests use real message authors, preserve task ownership, and await exact automatic handoffs. No production identity policy changed. - Current head `aa39275a1f300f7d1a0b16cd0885eea567cff6b0` includes current master and the native context-source projection. The focused identity/status cohort passed 27 tests and plain server typecheck passed. Fresh full repository tests, types, build, required CI, and Greptile review are pending. Final results will be updated before merge. - This is deterministic local-provider evidence. It is not a claim of complete live-provider qualification. ## Risks - This changes authenticated recovery and close ordering. The TypeScript transport and runner binary must be built from the same revision. - Failed or incomplete evidence intentionally prevents reuse and can require a fresh run. - PRP v1 ordinary/cold sessions remain supported. A v1 connection lease cannot upgrade in place. A current v2-capable runner held on a v1 lease was qualified through owned-process retirement/join, fresh bootstrap on the same old authority, v2 observation/ACK, then warm rotation. Legacy binary replacement and adopted-owner migration are not qualified by that test; rollout must not present them as automatic same-lease upgrades. - This pull request has no database migration or chat-channel activation. The second pull request keeps the channel feature experimental. ## Model Used OpenAI Codex assisted with implementation, tool execution, tests, and reconciliation. The existing implementation records OpenAI `gpt-6-astra` assistance. The current environment does not report a context-window size. No private reasoning traces are included. ## 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 - [ ] 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 - [ ] All Paperclip CI gates are green - [ ] 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 --- .../paperclip-runner/docs/durable-recovery.md | 29 +- .../runner-core/src/acpx_provider_backend.rs | 32 +- .../src/bin/fake-codex-app-server.rs | 378 +- .../crates/runner-core/src/codex_provider.rs | 382 +- .../crates/runner-core/src/durable/mod.rs | 9 +- .../crates/runner-core/src/durable/runner.rs | 2739 ++++++++++- .../crates/runner-core/src/durable/state.rs | 1104 ++++- .../runner-core/src/durable/transport.rs | 93 +- .../src/native_provider_backend.rs | 52 +- .../runner-core/src/process_supervisor.rs | 12 + .../runner-core/src/provider_backend.rs | 1843 ++++++-- .../crates/runner-core/src/provider_bridge.rs | 98 +- .../runner-core/tests/codex_provider.rs | 1135 ++++- .../backends/harness-driver-backend.test.ts | 10 +- .../src/backends/harness-driver-backend.ts | 24 +- .../src/backends/runtime-context.test.ts | 309 +- .../src/backends/runtime-context.ts | 82 +- .../paperclip-runner/src/contracts/codex.ts | 2 +- .../src/contracts/completion-result.test.ts | 124 + .../src/contracts/completion-result.ts | 43 +- .../durable-prp-control-plane.test.ts | 1211 ++++- .../durable-prp-control-plane.ts | 1116 ++++- .../src/control-plane/prp-transport-types.ts | 19 + .../codex/codex-app-server-driver-impl.ts | 59 +- .../codex-app-server-driver.lifecycle.test.ts | 8 + .../codex-app-server-driver.recovery.test.ts | 60 +- ...app-server-driver.semantic-results.test.ts | 83 + .../codex/codex-app-server-driver.test.ts | 145 +- .../drivers/codex/codex-boundaries.test.ts | 42 + .../src/drivers/codex/codex-boundaries.ts | 13 +- .../src/drivers/codex/codex-driver-values.ts | 3 +- .../drivers/codex/codex-harness-session.ts | 20 +- .../codex/codex-protocol-integrity.test.ts | 1054 +++-- .../codex/codex-session-server-requests.ts | 11 +- packages/paperclip-runner/src/index.ts | 8 + .../src/live/live-session.test.ts | 5 +- .../src/live/runnerd-codex-transport.test.ts | 4191 ++++++++++++++++- .../src/live/runnerd-codex-transport.ts | 1951 ++++++-- ...nnerd-final-output-burst.benchmark.test.ts | 354 ++ .../src/mock-core/codex-runner.test.ts | 41 + .../src/mock-core/codex-runner.ts | 11 + .../src/native-session-runtime.test.ts | 482 +- .../src/native-session-runtime.ts | 102 +- .../fake-final-burst-codex-app-server.mjs | 161 + ...artbeat-responsible-user-invariant.test.ts | 80 +- .../heartbeat-run-status-payload.test.ts | 44 +- .../__tests__/issue-recovery-actions.test.ts | 284 +- .../services/execution-recovery-resolution.ts | 30 +- .../services/heartbeat-run-status-payload.ts | 8 +- server/src/services/heartbeat.ts | 123 + 50 files changed, 18439 insertions(+), 1780 deletions(-) create mode 100644 packages/paperclip-runner/src/live/runnerd-final-output-burst.benchmark.test.ts create mode 100644 packages/paperclip-runner/test/fixtures/fake-final-burst-codex-app-server.mjs diff --git a/packages/paperclip-runner/docs/durable-recovery.md b/packages/paperclip-runner/docs/durable-recovery.md index ab1480ac03..2db53a8ab0 100644 --- a/packages/paperclip-runner/docs/durable-recovery.md +++ b/packages/paperclip-runner/docs/durable-recovery.md @@ -33,7 +33,7 @@ The connection starts in this order: 6.
