From 827bd21017a3694e8dd6fc3e4171fe9a0d4468ba Mon Sep 17 00:00:00 2001 From: Dotta <34892728+cryppadotta@users.noreply.github.com> Date: Wed, 11 Nov 2026 17:30:32 -0600 Subject: [PATCH] fix(recovery): retry lost-lease preparations instead of holding them for reconciliation (#20936) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - Run recovery restarts work that stops for infrastructure reasons, and keeps saved files safe > - A legacy Runner run can lose its controller lease while it prepares the workspace, before any provider work starts (`controller_lease_lost` with `executionRecovery: { kind: "bootstrap", providerWorkStarted: false }`) > - Such a run has no unsaved provider state, but recovery still blocked the task: either a saved-files hold that ends in `source_unavailable`, or an immediate "No live execution path" block after one failed continuation retry > - Recovery must work without a person, and a shown Retry must work > - This pull request lets lost-lease preparations use the existing interrupted-preparation settlement, and lets the bounded stranded-task sweep retry a continuation that failed before provider work > - The benefit is that these tasks retry automatically, and tasks that an older release already blocked recover after deploy ## Linked Issues or Issue Description Refs #20924 (fixes the lease renewal starvation that caused the lost leases; this PR fixes what recovery did afterwards). **What happened?** A staging burst of lost controller leases stopped many legacy Runner runs while they prepared the workspace. No provider work started. Most of the affected tasks then became blocked. One shape kept a saved-files hold (`legacy_execution_requires_reconciliation`). Its file recovery ended `exhausted` with `source_unavailable`, because the workspace had already retired the prepared epoch back to the last save. The hold never settled. The other shape was a continuation retry that also lost its lease. The release path blocked the task at once with "No live execution path", although `controller_lease_lost` is a transient cause with a 3-attempt budget in the stranded-task sweep. **Expected behavior** A run that fails before provider work starts retries automatically, within a bounded budget. It never needs reconciliation. If the prepared workspace is gone, the task continues from the last committed save. **Steps to reproduce** 1. Start a legacy Runner run with a remote workspace. 2. Make the controller lose its lease while the run prepares (before provider dispatch). 3. Let restore recovery record a saved-files hold, and let the workspace retire the prepared epoch. 4. See that the hold stays `resolved/blocked` with `source_unavailable`, and the task stays blocked. **Paperclip version or commit** master at c1edb9ec02. **Agent adapter(s) involved** Not adapter-specific (core bug). Seen with `paperclip_runner` (Daytona sandbox). ## What Changed - `server/src/services/cancelled-native-startup.ts`: `isInterruptedNativePreparationCandidate` accepts a failed `controller_lease_lost` run with the bootstrap certificate (`providerWorkStarted: false`), the same as a certified `process_lost` run. The error label alone still grants nothing. This lets the existing `legacy_interrupted_preparation_hold` settlement, terminal-time proof, status receipt, and `interrupted_preparation` retry lane apply to these runs. - `server/src/modules/wake-queue/*`: the release snapshot carries `retryableBeforeProviderWork` (bootstrap certificate plus a `transient_infra` continuation classification). When an automatic continuation retry failed for such a cause, release returns `released` instead of blocking. The stranded-task sweep then retries with its existing backoff and 3-attempt cap, and blocks only after that budget is spent. Non-retryable causes, uninvokable agents, and failures after provider work still block at once. - `doc/execution-semantics.md`: documents both rules. - No migration. Holds saved by the running release are settled by the existing ownership reconciler after deploy. ## Verification - Red then green, in the staging shape (failed `controller_lease_lost`, `renewal_deadline` lease-loss evidence, `restore_failed` with `workspaceRestoreRecovery`, exhausted `verify_execution` with `source_unavailable` / `use_alternative_strategy`, retired prepared epoch): - `src/__tests__/interrupted-preparation-hold-settle.test.ts`: before the fix, both new cases fail (`settled: 0`). After the fix, the hold settles as `false_positive`. With the status receipt, the task returns to `in_progress` and one `interrupted_preparation` successor is queued. For a hold saved by an older release without a receipt, the execution gate clears and one Retry starts a run. A lost lease without the no-provider-work certificate stays held. - `src/modules/wake-queue/domain/policy.test.ts` and `application/use-cases.test.ts`: before the policy change, the two new release cases fail (the task is blocked). After it, a pre-provider lease-loss retry failure is released to the sweep, and other failures still block. - `src/modules/wake-queue/adapters/retryable-before-provider-work.test.ts`: classification of the release snapshot fact. - `pnpm verify` and server `tsc --noEmit` pass locally. ## Risks - Lost-lease preparations now use the `interrupted_preparation` retry lane. That lane is uncharged but bounded at 12 retries, and it does not revive a chain whose failure budget is spent. - A released continuation waits for the stranded-task sweep (30 s reconstruction, plus backoff) instead of a direct requeue. The sweep's budget bounds the chain. - Settlement still needs every existing proof: the controller is gone or settled, leases are released with stop receipts, there are no execution events or native coordinator, and the prepared epoch is retired or the files are repaired. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.

When an automatic continuation retry itself fails before provider work started, for a cause the stranded-task sweep classifies as transient (such as `controller_lease_lost`), releasing the run does not block the task at once: the sweep retries it with its bounded backoff and blocks the task only after that budget is spent. Its `interrupted_preparation` successors count toward the same consecutive continuation budget and carry the chain's retry accounting, and an immediate continuation inherits that accounting, so alternating between release and recovery never resets either limit.
