## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The local heartbeat/runtime subsystem starts long-running local agent processes and records their run state. > - Operators sometimes need to rebuild and restart the Paperclip server while local agent processes are still alive. > - A normal restart should remain conservative, but a guarded production hot restart needs an explicit marker, startup reconciliation, and an inspectable report. > - The broader hot-restart PR is currently merge-conflicted, so this pull request lands the minimal server-side recovery path on current `master`. > - The benefit is that deploy operators can restart from a current branch without reverting production changes and without marking adopted live runs as `process_lost`. ## Linked Issues or Issue Description No public GitHub issue exists for this deploy-safety fix. Bug fix: - What happened: the current deployable `master` branch did not include the hot-restart marker CLI, startup adoption report path, or health version proof needed by guarded service restarts. - Expected behavior: a deploy operator can write a one-shot marker before restarting, the old server snapshots eligible running child processes, the new server reports adopted/finalized/lost runs, and adopted live runs are not reaped as `process_lost`. - Steps to reproduce: restart a server with running local child-process heartbeat runs without the marker/adoption path; startup orphan reaping has no adoption metadata and treats live detached children as lost. - Paperclip version/commit: fixed on top of `master` at `b606869a6`. - Deployment mode: production/local-service style deployments that rebuild and restart the primary `paperclip.service`. - Related PR: Refs #9628. This PR intentionally lands a smaller deploy-safe subset because #9628 is currently merge-conflicted. - Duplicate search: searched public PRs/issues for `hot restart` and `process_lost adoption`; #9628 is the directly related prior implementation. ## What Changed - Added `scripts/request-hot-restart.ts` to write a one-shot hot-restart intent marker under `PAPERCLIP_HOME`. - Added `server/src/services/hot-restart.ts` for intent/report path resolution, parsing, atomic writes, shutdown snapshots, and marker cleanup. - Wired server shutdown/startup so explicit hot restarts snapshot active runs, skip the normal heartbeat drain, reconcile live child processes on boot, and write `hot-restart-report.json`. - Preserved adopted run metadata so normal orphan reaping does not regress adopted live runs to `process_lost`. - Added `serverVersion` health proof alongside existing `version`, plus docs and regression coverage. ## Verification - `pnpm vitest run server/src/__tests__/health.test.ts server/src/__tests__/heartbeat-process-recovery.test.ts` — 2 files passed, 100 tests passed. - `pnpm --filter @paperclipai/server typecheck` - `env PAPERCLIP_HOME="$PAPERCLIP_RUN_SCRATCH_DIR/hot-restart-cli-smoke" pnpm --filter @paperclipai/server exec tsx ../scripts/request-hot-restart.ts --server-pid 12345` - Branch ancestry checked after `git fetch origin master`: `origin/master` was `b606869a6`, and `HEAD..origin/master` was empty. ## Risks - Medium risk: process adoption depends on PID/PGID metadata and the service manager leaving child processes alive for the guarded restart. - Normal restarts remain conservative, but an incorrect marker PID intentionally falls back to graceful drain instead of adoption. - The PR is server-only and does not include the broader UI/experimental-setting work from #9628. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first.
