## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The control plane recovers in-progress records after a server restart through a shared ownership path > - Run-less sandbox leases (login, probe, harness verification) were released only by a five-minute idle sweep > - That sweep releases by age: it leaves a dead holder's sandbox for minutes and takes a live login session's sandbox > - This pull request settles a run-less lease only when its stamped holder is proven gone > - The benefit is no stuck sandbox after a restart, and no live session loses its sandbox ## Linked Issues or Issue Description Related: #19965 (named the owner of login/probe leases), #19964 (the run-lease settle this mirrors). No duplicate PR was found. **What happened?** The final Daytona chaos wave `w-20261108T083036-s9401` recorded I2 `environment_login_probe_lease` (`pid_dead`) on 2 records. These were the codex agent's harness-verification leases. A restart killed their holder. The leases stayed `active` until the five-minute idle sweep released them. The same sweep releases any run-less lease after five idle minutes, also when its holder is alive. **Expected behavior** A run-less lease is released as soon as its stamped holder is proven gone. A lease whose holder is alive is never released, however long it is idle. **Steps to reproduce** 1. Start a Daytona wave: `node cli/node_modules/tsx/dist/cli.mjs tests/restart-chaos/main.ts --env daytona --daytona-image <image>` (K1/K4 faults). 2. Let a fault kill the server while an agent's harness verification holds its sandbox lease. 3. See the reconciler report I2 `environment_login_probe_lease` until the idle sweep releases it. **Paperclip version or commit** `master` at `8475826d2d`. ## What Changed - New `settleEnvironmentLoginProbeLease`, registered on `environment_login_probe_lease`. It runs only for a stamped holder that is proven gone, and compares and swaps on that exact stamp. - It moves the lease to `pending_cleanup` with the recovered-orphan reason, so the cleanup sweep destroys the sandbox in its next tick. - It leaves the lease alone when a legacy shutdown fence applies, or when another live lease holds the same provider resource. - The idle sweep for run-less leases now covers only legacy rows saved before holders were stamped (no `leaseController` key). Stamped rows are never released by age. - `holderUnchanged` is now exported from the run-lease settle so both settles share it. - The controller stamp (`leaseController`, and every other `ControllerProcess` stamp) now records the platform deployment when the platform names one (Railway: project, environment, service, deployment, volume). `controllerStamp` passes it to `proveOwnerGone`. A container redeploy changes the PID space, and the old stamp would read `different_process_space` (unprovable) forever. Now the existing `deployment_replaced` proof shows the old holder gone. This also covers `environment_run_lease_active` and the other kinds built on `controllerStamp`. - `currentDeploymentIdentity` in `owner-proof.ts` now delegates to `currentControllerDeployment`, so there is one parser. - Data doc: added the final Daytona wave, the six Daytona-only crash points (4 pass, 2 not reached, no violations), and the cause of the roughly 450 s codex TTFT. Runs waited behind the agent's harness verification, which restarted after each fault; boot itself took about 32 s. - Restart-chaos README: corrected which Daytona crash points a plain task reaches. ## Verification - Red, before the change: `environment-login-probe-lease-ownership.test.ts` failed 3 of 6. No settle happened, and the idle sweep released 3 live holders' leases. - Green: `pnpm exec vitest run` passes for `environment-login-probe-lease-ownership`, `environment-run-lease-ownership` and `heartbeat-orphaned-active-lease-sweep` (45/45), and for `environment-lease-owner-stamps`, `heartbeat-observed-workspace-preservation`, `ownership-reconciliation-report`, `heartbeat/recovery` and `workspace-recovery-warm-handoff`. - Redeploy: a stamp from a replaced Railway deployment settles with `deployment_replaced`. A stamp from the same deployment in another PID space stays `active`. This was red when `controllerStamp` dropped the deployment. - Live-owner counter-cases: the current process, another live PID, another PID space, and a lease re-stamped after the proof all stay `active`. A read-only pass never settles. - Not re-run live: the Daytona wave and crash points ran before this fix. The next Daytona wave should show no `environment_login_probe_lease` I2. ## Risks - A stamped run-less lease whose live holder never releases it, because of a bug in that process, is no longer released after five idle minutes. It is released once that process exits. This is the intended trade: never take a live holder's sandbox. - On an ephemeral server without a platform deployment identity (not Railway), a stamp from a replaced container is still unprovable. Such a run-less lease stays `active` until the provider expires the sandbox, and the reconciler reports it as unprovable. Before this PR, the five-minute sweep released it by age. This is the same open gap as unstamped legacy leases on an ephemeral server: there is no operator action yet. It is listed as a Phase 2 follow-up. - Legacy unstamped run-less leases keep the age fallback. These are rows written before #19965, and no current code writes them. ## Model Used - Anthropic Claude Opus 5.5 (`claude-opus-5-5`), via Claude Code with tool use. ## 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 - [ ] 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
