## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - A task run takes an environment lease (for example a Daytona sandbox) before the agent starts. No provider work happens before that lease exists. > - Only a provider HTTP status or a connection errno counted as a transient lease failure. #20828 (merged while this was open) added the Daytona acquisition deadline. A database error while the lease was recorded, a plugin RPC deadline, and an unfinished provisional creation still did not count. > - Those failures became a generic `setup_failed` with no bounded retry. And when the bounded retries of any `environment_provider_unavailable` failure were used up, recovery still put the task on a board-owned `stranded_assigned_issue` action. > - A hosted instance saw this for six runs in 45 minutes when concurrent runs rose from about 8 to about 20. Two tasks stayed blocked and waited for the board. > - This pull request classifies every lease acquisition failure that has structured transient evidence as `environment_provider_unavailable`. When the bounded retries are used up, the task rests on a system-owned action and a working Retry. > - It also adds the restart-chaos fault EP1, so the harness covers lease acquisition failures from now on. > - The benefit is that a busy or slow sandbox provider no longer strands tasks on the board. ## Linked Issues or Issue Description No public issue exists. **What happened?** Five runs failed with `Failed to acquire lease for environment "Paperclip Sandbox" (sandbox): Daytona lease acquisition timed out; allocation cleanup is pending` after 5 to 6 minutes in `preparing`. One run failed with `Database query failed (lease_acquire_failed)` within 10 seconds. Every run recorded `executionRecovery: { kind: "bootstrap", providerWorkStarted: false }`, but the error code was `setup_failed`. No run got a bounded retry. Two tasks were left `blocked` with a board-owned `stranded_assigned_issue` recovery action. **Expected behavior** A lease acquisition failure happens before any provider work. The run must retry with a bounded, visible backoff. When the bound is used up, the task must rest with a Retry that works, and no board-owned recovery action. **Steps to reproduce** 1. Make lease acquisition fail with the provider's acquisition deadline (the validated acquisition diagnostic that the environment runtime records), or with a database driver error. 2. Let the run start. 3. Before this change, the run fails with `setup_failed`, no retry is scheduled, and recovery creates a board-owned `stranded_assigned_issue` action. ## What Changed **How this PR and #20828 divide the problem.** #20828 (merged) makes the Daytona plugin end a stuck create early and classifies the acquisition-deadline envelope as `environment_provider_unavailable`. This PR does not change the Daytona plugin or that deadline path. It adds only what #20828 leaves out: - a lease-acquisition failure that is not a create timeout: the plugin RPC deadline (`-32003`) and an unfinished provisional creation recorded for this run; - a transient database error while the lease is recorded; - the exhausted state: a system-owned recovery action and Retry instead of a board-owned `stranded_assigned_issue`, for every `environment_provider_unavailable` cause (including #20828's); - the chaos fault EP1 (EP1, EP1N, EP1D). - `readTransientLeaseAcquisitionFailure` (`server/src/services/environment-provider-unavailable-error.ts`) classifies a lease acquisition failure as transient when it has structured evidence: the provider status or errno (as before), the run's own validated acquisition diagnostic (deadline or unfinished provisional creation), the plugin RPC deadline, or a transient database error (a postgres.js connection code, or SQLSTATE class 08 or 53, 57P01-57P03, 57014, 55P03, 40001, 40P01). A deterministic SQL error (syntax, schema, constraint) is not retried. A definite non-transient status (for example HTTP 401 or 404) is still `setup_failed`. Message text is not parsed. - `environment-run-orchestrator.ts` uses this classifier, so these failures get `environment_provider_unavailable` and the existing bounded bootstrap retry (30 s, then 60 s, with jitter). The task shows "retry scheduled" while it waits. - When the retries are used up, recovery uses the cause `environment_provider_unavailable` with a system-owned action and no board routing. The notice says "Retry when ready" and does not ask for a board decision. The task's Retry starts a new acquisition. - Restart-chaos fault EP1: a test-mode server seam (`environment-lease-fault-injection.ts`, read from `PAPERCLIP_CHAOS_LEASE_FAULT_CONTROL`, ignored in production) throws the staging error shapes before any provider call. `tests/restart-chaos/env-provider-wave.ts` runs EP1 (deadline twice, then success), EP1N (deadline forever, then Retry after disarm) and EP1D (database error once). The oracle fails on any `setup_failed` run, any board-owned recovery action, a wrong retry count, or a task that does not complete. - Docs: `doc/execution-semantics.md` and `tests/restart-chaos/README.md`. ## Verification - RED on `origin/master` (`1d67e309e0`, before #20828): the three new tests in `heartbeat-process-recovery.test.ts` ("transient sandbox provider refusal during lease acquisition") fail with the staging result: `expected [ [ 'failed', 'setup_failed' ] ] to deeply equal [ [ 'failed', 'environment_provider_unavailable' ], [ 'scheduled_retry', null ] ]`. On current master the deadline now retries (#20828), but the exhausted case still rests on a board-owned `stranded_assigned_issue` action (the existing HTTP 502 exhaustion test showed `ownerType: "board"` before the recovery change), and the database error is still `setup_failed`. - GREEN: `pnpm --filter @paperclipai/server exec vitest run src/__tests__/heartbeat-process-recovery.test.ts -t "lease acquisition"` passes 5 of 5. This includes the deadline and the database error that retry once and then complete, and the deadline that never clears. That task rests `blocked` with a system-owned action, `canRetry: true`, no execution blocker, and Retry completes it. - Unit tests: `environment-provider-unavailable-error.test.ts` + `environment-lease-fault-injection.test.ts` (56), `tests/restart-chaos/env-provider-faults.test.ts` (6) pass. - Related suites pass: `environment-run-orchestrator`, `task-interruption-query`, `issue-recovery-actions`, `issue-recovery-deadlines`, `stranded-notice`, `heartbeat-native-resume-lease-failure`. - `server` and `tests/restart-chaos` typecheck pass. - Chaos waves (local, Codex `gpt-6.1-sol`, head `1bd387e98f`; the later head changes only database classification and the notice), all pass: - EP1 `w-20261111T171803-s71-ep`, 2 tasks: each had exactly 2 `environment_provider_unavailable` runs, then succeeded with no user action, no board-owned recovery action, brief oracle pass. - EP1D `w-20261111T172850-s73-ep`, 1 task: 1 failed run on the database error, then succeeded. - EP1N `w-20261111T173346-s74-ep` (and `w-20261111T162752-s72-ep` before the rebase): 3 failed runs, the task rested `blocked` with `canRetry: true` and no board-owned action; after disarm, Retry completed it. - No Daytona wave was run. The fault is injected in the server before the provider call, so a local instance reaches the same retry and recovery code. ## Risks - More failures now retry, all bounded. Only transient SQLSTATEs retry. The staging database error recorded no SQLSTATE. If it was a deterministic SQL error, it still fails `setup_failed` and goes to the board as before; that is intended, because a retry cannot fix it. - Each retry is a new creation attempt with its own creation record. A provisional allocation whose cleanup is pending stays with its record and the creation reconciler, as before. - The retry bound is the shared bootstrap bound (two retries). A provider outage longer than about 15 minutes still rests on Retry, but no longer on a board action. - The fault seam reads a file only when the environment variable is set, and never when `NODE_ENV=production`. - Saved state from the previous release: no persisted shape changes. A task already stranded on a board action keeps it (`preserveExistingOwner`). New failures use the new cause. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.
