## Thinking Path > - Paperclip manages AI agents and their work. > - Native sessions retain provider state across execution attempts. > - A same-run retry can receive a replacement plugin task lease. > - The executor loaded the old task checkpoint only for crash recovery. > - An ordinary retry could fail its local authority check before reading that checkpoint. > - This change restores the checkpoint through the existing authorized lease transfer. ## Linked Issues or Issue Description **What happened?** A native provider turn ended without its completion result. Paperclip scheduled an exact-checkpoint retry on the same heartbeat run. The retry acquired a new plugin task lease, then failed with `runner_state_identity_mismatch: authority_indeterminate`. The checkpoint restore branch required a `resume_dead_runner` restart claim. Ordinary same-run retries have no such claim. A controlled fixture with a retained remote checkpoint and no local lifecycle receipt reproduces the error. The original controller file contents were unavailable, so that part of the incident mechanism remains inferred. **Expected behavior** Load the retained plugin checkpoint after the existing policy proves the lease transfer is safe. Keep the original run, session, and saved control journal. Reject an unverified predecessor or a changed checkpoint identity. **Steps to reproduce** 1. Start a native session through a plugin task environment. 2. End its provider turn without a completion result and retain its checkpoint. 3. Retry the same run on a replacement task lease without a restart claim. 4. With no local lifecycle receipt, observe the authority error before the checkpoint read. **Paperclip version or commit** Reproduced against source `507dc70be26c191e372f09e58dc0965e73bf8f57`. **Deployment mode** Native Runner with a plugin task environment. The observed provider used ACPX Claude. The controlled executor fixture uses the shared native boundary. Related work: #17439 concerns recovery after controller replacement. This fix uses the existing checkpoint contract and does not depend on that PR. ## What Changed - Restore prior plugin state for an ordinary same-run attempt when its lease changes. - Keep the existing company, agent, workspace, retained-state, and termination checks. - Extend executor regressions for ordinary retries, mismatched checkpoints, and missing stop proof. - Exercise the same-run checkpoint read through the database-backed task API. - Document the recovery rule and verification recipes. ## Verification - Failing before: the ordinary retry reproduces `authority_indeterminate`. Both new denial cases also fail because the old branch never reaches the transfer policy. - Passing after: all six focused checkpoint cases pass. The saved control journal stays byte-for-byte unchanged. Rejected cases do not construct a provider backend. - `pnpm -r typecheck` passes. - Map and module-boundary checks pass. - All 858 executor, database lease-authority, plugin task, and ownership tests pass. `pnpm build` passes. - The broad local `pnpm test:run` attempt did not complete. It hit a 20-second timeout in the existing historical workspace-recovery HTTP Retry case. That exact case then passed in isolation on the unchanged head. The broad local attempt was stopped after the full CI matrix passed; it is not counted as a local pass. - Greptile reviewed current head `5bc11fa978ab87d3d9c5d575fa9666185aaafc2c` at 5/5 with no actionable findings. The full current-head CI matrix passed on attempt 2: 55 checks passed, no pending or failed checks, and two expected Storybook jobs skipped. - The first broader local attempt could not bind embedded PostgreSQL inside the sandbox (`EPERM`). It was stopped and restarted with loopback access. This was a setup failure, separate from the observed red regression. - The first CI attempt failed two existing checks: the process-adapter signoff happy path exhausted its run wait budget, and the workspace export scheduler did not reach `complete` within 20 seconds. Both tests pass in isolated local runs on the unchanged head. Both failed shards passed on their single rerun without code changes. The initial failures remain recorded. Their timing cause is not proven by the later passes. - Live acceptance at the fixed revision has not run. The hosted workspace still serves the earlier release. No deployment or retry of the original task is claimed. ## Risks The new checkpoint read runs only for same-run plugin recovery with a replacement lease. Missing termination proof, changed scope, or a changed Runner identity still stops execution. The lease resolver owns these checks. The fix does not replay tools or change retry budgets. A turn that omitted its completion result still needs the existing bounded continuation to finish useful work. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository tools, and code execution. The runtime does not expose a more specific backend 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 (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 - [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>
Paperclip agent access map
This map accompanies the feature map. It records APIs, agent entry points, permission boundaries and verification for the same capability IDs. The shared contract defines the format and maintenance rules.
The chat scenario catalog uses these same IDs for human requests and expected outcomes. Its scenarios retain the access boundaries here; neither a CEO role nor a planned scenario grants board authority or establishes a working production tool binding.
Use full capability IDs when referring to access contracts outside their file:
onboarding/company means the company capability in onboarding.md in both maps.
The feature index lists feature and
capability IDs; IDs and references
explains entry-point references and stable naming.
Browse access contracts
The same-named feature recipes define navigation and capability IDs. Run
node scripts/storybook-catalog.mjs for the generated

published feature guide.
Add or update the affected companion; there is no central registration or count.
Existing baseline source references describe the original inspection, not current verification. Record new executed evidence in the PR, issue, or CI artifact with its revision and scope. Do not refresh unrelated headers as bookkeeping.
Using an entry
Read its Policy and Gaps before selecting an agent path. Native fallback, legacy
REST/CLI, stdio MCP and a personal assistant connection can have different
authority and availability. Use a real admitted production binding; a scenario
declaration is not an installed tool. A restricted entry records current
enforcement and leaves any unresolved delegation decision visible.
For API catalog disagreements, follow the route/service authorization and record
discovery drift. For not-applicable, retain the concrete exception and local
path. Split shared business operations from client-only presentation.
Use maintain-verification-skill to reconcile changed source and both maps.
Use verify-paperclip and existing API/runner/MCP fixtures to collect the
permitted-agent and denial evidence; report blocked/not-run coverage honestly.
Run node scripts/check-maps.mjs after editing. The structural check does not
certify permissions, API catalog coverage, tool admission or live behavior.
Native REST transport
The call_api parity change reconciles affected baselines against
58e16dbddfc9c8d0cf60867f9d9847f0feda055b and the changes in this PR. Ordinary
REST operations use the same route authorization as legacy agent REST. Dedicated
tools remain optional for those operations; protocol endpoints still need their
existing clients. Board-only routes remain restricted for agent identity.
Native search_api / call_api requires operator rollout admission, a running
authorized native run, current task assignment and execution-run binding, company
and budget authority, task privacy, and a permitted work mode. Ask and Plan retain
mutation restrictions, and runs retain their admitted JWT scope during restart
recovery even when task mode changes. A waiting
agent does not gain independent native control just because a REST route exists.
Credential-bearing replies, including company exports and their legacy alias, stay inline under a 10 MiB limit and use encrypted mutation receipts. Other saved API snapshots are limited to the issuing actor and responsible user, plus authorized administrators. Artifact uploads enforce the same access checks as downloads; private snapshots are excluded from company exports and public company logos. Explicit deliverables use the existing sharing path. Native event history, checkpoints and completion records omit API bodies while preserving receipt metadata and replay digests. Restored webhook secrets use the same encrypted receipt and inline response policy as newly created webhook secrets. Task image access requires the company boundary and the task permission; skill-test and low-trust agents do not need company-wide browsing authority. Completion replay applies the same idempotent projection to stored and expected payloads; the run-log guide describes its fields.
