## Thinking Path > - Paperclip coordinates agent work and keeps its authority in the server. > - Remote native runners can preserve execution through a server replacement. > - Deployment operators need evidence that current runs support that recovery. > - Process-local drain counters do not establish this fact. > - This PR adds an optional, operator-only readiness observation from existing records. > - A deployment consumer can use that report while the existing runtime retains recovery authority. ## Linked Issues or Issue Description Refs #17439. **What happened?** A deployment cannot distinguish recoverable remote native executions from runs that require a task drain. The existing status endpoint reports only process-local counts. **Expected behavior** An instance operator can request a bounded readiness report without stopping admission or exposing checkpoint material. Missing ownership or persistence evidence must prevent readiness. Ordinary status reads must keep their current cost. **Steps to reproduce** Run a remote native task. Read the task-drain status. It reports active work but supplies no recovery eligibility. Deployment code therefore has no affirmative signal to select an active-run handover. ## What Changed - Add `GET /api/instance/task-drain?upgradeReadiness=1` for instance administrators and existing Cloud control callers. - Return aggregate eligibility from current run identities, controller leases and bound opaque checkpoint headers. Unknown work, pending admission and incomplete reads prevent a positive report. - Bound the explicit read to 1,001 rows, encrypted headers of at most 256 KiB each and 8 MiB total, and a two-second SQL statement timeout in a read-only transaction. Keep ordinary status reads in memory. - Add PostgreSQL, count-transition and route authorization tests. Update the API contract, operator docs and access maps. ## Verification - All seven readiness cases pass against an isolated PostgreSQL 18 fixture. They cover missing checkpoints, legacy adapters, missing process/session identities, foreign owners, expired leases, missing lease tokens, failure state and in-flight work. The positive SQL fixture uses the real Runner checkpoint writer and encryption. Regular sandbox workspace identity and plugin environment-lease identity are tested with independent IDs. Stopped/released/undispatched plugin tasks and every mismatched identity field are rejected. Local/legacy/malformed/oversized or mismatched headers are rejected. A held PostgreSQL table lock proves the two-second cancellation budget, rollback/connection release and unrelated query responsiveness. - All 123 focused readiness, instance-settings and Cloud control assertion tests pass, including operator-only access and no readiness read on ordinary status requests. Runner’s 168 checkpoint tests pass. Runner and server typechecks pass after review fixes. - Workspace typecheck, full build, module-boundary and map checks passed locally before the master rebase. Current-head GitHub CI is now green, including typecheck, build, all grouped/serialized server and Runner tests, browser shards, policy and review-dispatch checks. Greptile completed cleanly at 5/5 for `f15fb0c7e9dfb975090cd5d791a1c8e6701275f8`; all actionable threads are resolved. - The broad local test run was stopped after the macOS embedded PostgreSQL fixture failed to bootstrap. The SQL test was then run on the isolated PostgreSQL fixture. No assertion or timeout was weakened. One unrelated existing route test exceeded its 15-second limit under concurrent local builds; it passed on one isolated retry and the subsequent whole route suite passed. - Hosted active-run upgrade acceptance has not run. This PR supplies an observation; it does not change rollout policy or establish live continuity by itself. ## Risks This is an instance-wide observation, so company members and agent keys must not receive it. A readiness snapshot can age as work changes; shutdown and startup retain their existing execution authority and fencing. The report does not validate a replacement artifact or authorize a schema migration. It decrypts only bounded headers through the checkpoint owner and delegates format/identity inspection to Runner; full journal restoration and physical sandbox authentication remain with recovery. No migration, recurring query, new checkpoint write or wire protocol change is included. The additive Runner header inspection contract reuses its existing parser. ## Model Used OpenAI Codex, based on GPT-6, with reasoning, source inspection, tool use and code execution. The host does not expose the exact serving model ID or context-window size. ## 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 and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass for the affected contracts; the broad-run limitation is recorded above - [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>
