## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Sandbox provider plugins run agent work in remote execution environments > - The Daytona sandbox liveness read can stay pending when the connection stops responding > - A pending read blocks the plugin until a broad host-to-worker limit expires > - This pull request adds bounded deadlines to Daytona liveness calls and clears stale handles > - The benefit is a fast and clear error when a Daytona connection stops responding ## Linked Issues or Issue Description Refs #11341 **What happened?** The Daytona sandbox liveness read had no per-call timeout. A silent connection failure left the read pending until the broad host-to-worker RPC limit expired. **Expected behavior** The plugin should stop a liveness call within a defined limit and report a clear timeout error. **Steps to reproduce** 1. Create a Daytona sandbox handle. 2. Make the cached handle freshness read never resolve. 3. Run the next sandbox operation. 4. Observe that the operation waits for the outer RPC limit without a liveness timeout. **Paperclip version or commit** `master` before this change. **Deployment mode** Any deployment mode that uses the Daytona sandbox provider. ## What Changed - Add `withLivenessTimeout` with timer cleanup and `SandboxLivenessTimeoutError`. - Bound `refreshData` with configurable `livenessTimeoutMs`, which defaults to 30000 milliseconds. - Bound sandbox start and recovery calls with the SDK timeout plus a 5000 millisecond margin. - Reject `livenessTimeoutMs` values above 86400000 milliseconds and document the setting. - Evict a cached handle after a failed freshness refresh so the next operation fetches a new handle. - Add a test for a never-resolving freshness refresh and the cached-handle eviction. ## Verification - Run the Daytona plugin test suite with its package Vitest configuration. - Confirm that 150 of 150 tests pass. - Confirm that the new test reports a bounded timeout and a fresh handle on the next operation. - Confirm that GitHub Actions reports green status checks after the pull request starts. ## Risks This change adds an early timeout only to Daytona liveness calls. A value of 0 or less disables the extra bound. The default leaves normal SDK calls within their expected time limit. The main risk is a timeout value that is too short for a slow but healthy connection. ## Model Used OpenAI Codex, GPT-5. The model used tool calls and code execution. The model supplied the PR handoff and did not author the code in this pull request. ## 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>
