## Thinking Path > - Paperclip manages agent work and its execution state. > - Remote Runner processes use health reads to check their saved process identity. > - A failed health request cannot prove that the process stopped. > - Three fast gateway errors can exhaust the old retry limit in half a second. > - The caller already gives these reads a shared 30-second recovery budget. > - This pull request uses that budget with backoff for read-only failures. > - A short gateway outage can then clear without stopping the existing turn. ## Linked Issues or Issue Description **What happened?** A transient HTTP 502 during sandbox process supervision caused an active native Codex turn to fail. The probe stopped after three attempts, even when most of its 30-second budget remained. The run reported `notification_transport_failed` and required workspace recovery. **Expected behavior** Retry read-only transport failures within the existing deadline. Keep process identity conflicts authoritative. Do not repeat a signal after a lost acknowledgement. **Steps to reproduce** 1. Start a read-only process verification with a 30-second deadline. 2. Return HTTP 502 from its first three transport reads, then allow the next read to succeed. 3. The old helper rejects after three reads. The fixed helper returns the successful observation. Related repairs: #16451 introduced bounded remote probes. #16835 and #17799 require proof of process exit before replacement. This change retains those guards. ## What Changed - Use the existing absolute deadline instead of a three-attempt limit for read-only probe failures. - Back off from 250 milliseconds to two seconds. Clip each request to ten seconds or the remaining budget. - Preserve the original error and diagnostic when the deadline is exhausted. Reject non-finite deadlines before an RPC. - Add a red/green regression and a repeated-gateway-failure case around a real listening process. - Update execution semantics and both recovery maps. ## Verification - Before the fix: the new probe suite failed two behavioral assertions. The gateway case returned its HTTP 502 error instead of the later successful observation. - After the fix: 75 focused probe, diagnostic, process-supervision and adoption tests pass. The diagnostic failure tests use a controlled clock for their full 30-second budget. Their error and redaction assertions stay unchanged. - Map alignment and module-boundary checks pass. - Full workspace typecheck and build pass at final commit `ddd42f66378ebc36ec1d7e0ca1f45943473561b3`. - The broader affected suite against disposable PostgreSQL passed 994 of 997 tests; its three startup/database timeouts passed unchanged in isolation. The initial full default local run encountered embedded PostgreSQL startup failures and did not complete. The four diagnostic tests that assumed the old short retry timing now use a controlled clock without weakening their assertions. - Incident evidence came from Linux AMD64, Node 24.22.2, Core commit `0c70cedce9a803bdc201324528abb35e423e7cd0`, native Codex `gpt-6.1-sol`, and a shared ChatGPT subscription. Two separate runs recorded the same supervision HTTP 502 within one second. - A disposable live Daytona sandbox check passed on Linux x86_64 and Node 24.22.1. Three injected gateway failures recovered in 3.31 seconds on production source from `e54a355fa179022caaa6854302ff56bd85de0229` (unchanged by the final test-only commit). The real Node listening process had one launch, retained its exact identity and saved file across a second read, and produced a confirmed Stop receipt. Sandbox deletion succeeded. This is process-supervision integration evidence, not a Codex task or model execution. - Fixed-revision hosted acceptance and recovery of the original conversation require rollout. This PR does not claim either. The duration of the original provider outage remains unknown. - Final commit `ddd42f66378ebc36ec1d7e0ca1f45943473561b3`: required `ci / verify` and `ci / e2e` checks pass; Greptile is 5/5 with no inline findings. The separate Paperclip Review service has not completed an assessment and remains queued. It is not a required branch check. ## Risks - Persistent fast transport failures cause more read-only requests within the same deadline. Capped backoff limits their rate. - Missing or changed identity still returns immediately. Failed health reads still cannot authorize replacement, process signals, or provider replay. - Signal requests still have one attempt. The timeout budget and execution permissions do not change. - No schema or package changes. ## Model Used - OpenAI GPT-6, through Codex, with reasoning, repository inspection, and shell tool use. The exact deployment model ID and context-window size are not exposed by this session. ## 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>

Recovery
People can see why a task stopped, who owns the next action, and whether a safe continuation is available. Recovery retains task context and ownership, honors pause and budget gates, and distinguishes confirmed failure from an uncertain external outcome. A retry acknowledgement alone is not proof that work resumed.
Feature ID: recovery.
Agent access: companion.
Sub-features
diagnosis:recovery/diagnosis— a task/run exposes the recorded cause, evidence, owner, attempt progress, and next action without requiring a raw-log interpretation.bounded-continuation:recovery/bounded-continuation— supported interrupted work continues with preserved conversation context and bounded attempts, without blindly replaying tools. Remote native runners can retain their active turn across main-server replacement using the encrypted Postgres controller journal. See the five-minute contract and qualification recipe in remote continuity. Restart recovery respects live heartbeat preparation before workspace synchronization finishes. PostgreSQL regressions cover unchanged ownership, no duplicate dispatch, and later recovery after preparation leaves the registry.source-action:recovery/source-action— source-scoped recovery actions remain attached to the task; independent repair work may have its own issue and return owner.exhaustion:recovery/exhaustion— an exhausted infrastructure attempt offers ordinary Retry. Internal repair stays system-owned; genuine user decisions retain their specific action.workspace:recovery/workspace— workspace divergence/export failures show the applicable repair, reconcile, or isolated reissue action with evidence and authority checks. Retained-file recovery runs in the harness with observed task progress and a ordinary Retry action after exhaustion or during backoff. It preserves newer files, keeps uncertain sources held, and delivers saved human input through ordinary admission. The task does not expose infrastructure-certification forms or a workspace link when the destination is disabled. Local PostgreSQL and real filesystem regressions cover native and legacy recovery and one-time delivery; hosted provider recovery remains separate acceptance. Daytona directory export can stream its archive when the sandbox cannot store a temporary tar. The transfer remains bounded and validates archive completion and paths before import. The capacity regression exercises a real local PTY and file-size limit. The credential-gated provider test covers stop/start, an ENOSPC archive sink, safe-link filtering, and a second export. Neither test proves the original task's continuation or repairs lost provider session state. Native finalization deadline failures also retain the exact prepared source for the same stop-and-save workflow before Retry admits another executor. A blocked native restart records that preservation obligation atomically with its failure. PostgreSQL regressions cover exact source binding, live ownership, rollback, and no replacement run or wake from file preservation. Retry reconstructs missing preservation for historical failures only from an exact prepared source without a live finalization owner. New messages and orphan cleanup can register missing preservation automatically and wake the existing worker. Saved input still waits for verified stop and file persistence, then enters ordinary admission once. A completed explicit Retry also retires its failed, unowned sandbox predecessor's stale retry and registers preservation atomically. Current task state and live or mismatched owners remain protected; workspace switching still waits for cleanup.unknown-outcome:recovery/unknown-outcome— uncertain external side effects require inspection and an explicit decision, not automatic replay.user-continuation:recovery/user-continuation— saved user messages after a stop are reconsidered once cleanup proves the old execution is stopped; duplicate wakes are avoided. A user comment that also reassigns the task retains this intent, including existing deferred assignment receipts. The comment's identity and author, current assignment, stop proof and normal execution gates remain required.reconnect:recovery/reconnect— browser stream recovery refreshes persisted state without claiming the agent itself restarted or that a failed run succeeded.
How to get to it (user POV)
For recovery/reconnect, also interrupt a write response after the server accepts
it. Keep a title draft bound to its original task while navigating. Restore a
new-task draft with its files selected in another order and require the same
creation key and one task. Verify lost document-create and decision responses,
including an interrupted verification read. Once the bounded retry budget ends,
require a visible Resend now action. Use
durable autosave tests and
task creation tests for the
controlled source cases; repeat the real browser journey for acceptance.
Switch accounts while an inline edit is open or a channel send waits to retry:
the next account must see neither private text nor a retry from the first account.
Returning to the original account restores its retained channel request with the
same key for explicit retry. Unowned legacy receipts stay held for Activity
inspection until a person explicitly discards their browser record; discard does
not replay the text or cancel an accepted update. Typing before the first session
lookup survives that initial lookup and is backed up under the resolved owner. Component evidence lives in the
inline editor tests and
connected-channel tests;
these controlled session changes do not establish hosted authentication acceptance.
Also switch accounts during a restored task create and while its files are
uploading: later uploads stop, the next account sees a fresh form, and the
original request key remains owned by the first account. Reselect colliding
text-document filenames in reverse order and verify their original keys and
contents. Switch between cached document subjects without copying either draft.
A receipt arriving before an in-flight resend must preserve the next message.
The startup browser journey in
disconnect recovery holds the
first session response while a title save waits, simulates an offline event with
API failures while keeping static assets reachable, then verifies the real saved
server title after account resolution and reload. The accepted-comment journey
then completes and assigns a task before repeating its saved comment request;
the original receipt must return once, its activity must appear once, and the task must stay Done. Reusing that
key with different text must return a conflict without changing the task. This
uses a disposable process agent and makes no provider call. A separate healthy-API
startup journey fails the session endpoint with JSON 500 responses, then restores
it while an edit waits; the same edit must save and survive reload without a
network reconnect or another user action.
source-task
Open the affected task from Tasks, Inbox/Blocked, search, or a direct task link. Observe one working, backoff, failed or waiting-for-user state. Use Retry after an infrastructure failure. No process or file certification is required.
A workspace project denial names the blocked access and links to the agent's Permissions / Trust settings. After an authorized person adds the required project, return to the saved task for an explicit Retry task action. Saving permissions alone does not wake the agent. Historical setup denials receive the same notice on reload; unrelated errors and prior assignees do not. Move a denied task to a project the agent can access while retaining a source from another project: the notice must stay blocked until the selected source is also allowed or an authorized workspace selection replaces it. A valid pending selection is checked for the next admission; a stale or unavailable selection must show a non-retryable failure without a project-permission repair action. Project changes alone preserve selected files.
Thinking appears immediately after Retry, before the request completes. Technical source/run details remain in deliberate diagnostics. The task recovery contract describes receipt identity, fresh workspaces, bounded retries, historical adoption and service incidents.
run-detail
Open the agent's run (/agents/:agentId/runs/:runId) from activity or the task's
run link. The run page hosts workspace repair controls only for a failed run
with error code workspace_validation_failed and a linked source task that still
has a live workspace_validation recovery action. Use the source task for other
stopped-run recovery checks. Native workspace export failures also offer the
read-only Inspect recovery control described in the
run diagnostic recipe. It observes one selected
source's recorded identity and does not retry, repair, or authorize execution.
operator-retry
The connected-task regression uses HTTP Retry after an accepted board message fails before provider startup. It checks the canonical intent, same-user identity and actual queue dispatch, then repeats Retry after another contained preparation failure with the same source and a new certified successor; edited source, contradictory execution evidence and mismatched receipts refuse or wait. This local boundary probe deliberately stops before a provider call, so it does not establish hosted recovery of the task.
Use the task's Retry action. It can create an isolated attempt after old execution is contained even when old-file preservation remains unresolved. Approval, credentials, budget and deliberate pause use their existing specific controls.
For a connected conversation, click Retry while an exact retained source still needs containment. Observe a saved wait with no new executor. After verified containment, the same chat receipt must admit one successor with the original source batch. Reload and repeat reconciliation. Check that a paused endpoint, changed source, superseded request or revoked access cannot start that work. The connected-chat database regression in chat channel integration exercises admission and queue continuation. It does not establish hosted provider recovery or successful delivery.
For GitHub, save a follow-up behind a failed run, then reconnect the same App. Click ordinary Retry and verify that one successor receives the saved follow-up instead of replaying the older request. Reload and repeat the same request key; there must be one successor and no duplicate publication. A second reconnect after admission, changed App, revoked sender or changed repository must prevent dispatch. An unadmitted rejection keeps the follow-up available for another deliberate Retry. Historical deliveries must remain unchanged. Repeat with legacy input that has no saved App ID and was refused by a budget before acknowledgement. An earlier processed response from the same endpoint, conversation and agent can prove its App claim. Missing, late, unlinked or conflicting proof must reject Retry. Verify actual execution separately. At dispatch, confirm the admitted successor retains the same source and resolved continuation receipt. If it fails at Retry authorization before provider startup, use the next ordinary Retry against that newest failed run. It must retain the saved follow-up and create one successor; output, an allocated environment or an active controller must prevent treating that failure as never started.
post-stop-message
After a stop, send a new instruction on the same task or inspect one already saved while cleanup was pending. Observe the waiting message, continuation, and eventual result rather than manually changing the task status to look complete.
A continuation denied before startup by an existing execution hold remains a wait. Once the original hold clears, the server verifies the dispatch receipt and absence of execution evidence, ignores any historical false incident for that unused admission, and reconsiders saved input through normal admission. No infrastructure-certification form is needed. The database regressions cover incident prevention, retained audit history, concurrent restart admission, ordered messages, contradictory execution evidence, and unchanged pause and task gates. These tests do not qualify a live provider or prove task completion.
browser-reconnect
While viewing an active or recovering task, interrupt the browser connection and restore it, or suspend and return to the tab. Reload is a separate check. The current task and run state should reconcile with the server.
For a consumed review path, verify that the one automatic repair run receives the instruction to save a one-shot monitor before it promises another check. Repeat with a fresh session, a resumed session, and a connection-pool retry that retains the typed repair marker but changes the wake reason. Confirm a persisted schedule before claiming that follow-up will occur; the repair instruction does not schedule one by itself. The wake regression exercises the real wake builder, serializer and prompt selector with an empty credential-history database boundary. It does not prove a hosted agent scheduled or completed the follow-up. Exhaustion still blocks for a board decision.
Driving it
Preconditions: follow the baseline. Use a disposable instance and reproducible failure. Record source task/run, adapter/runtime mode, cause, attempt count, current owner, and verified stop evidence. Do not kill an unrelated server or induce provider side effects just to get a failure screen. Use the existing deterministic recovery suite first.
Operation checkpoints
Use these checks alongside the entry-point recipes below and the operation records in the access companion. Record the actual actor, surface, saved result and denial separately. Source review and linked tests do not establish a live pass.
| Capability ID | Action and persisted result | Denial, race and retry checks |
|---|---|---|
recovery/diagnosis |
Open the source task and exact run; compare cause, source action, original owner, recovery owner, attempt bounds and next action after reload. | Test an unrelated/private task and a stale run notice. Read-side retirement of a stale action must not create a new attempt, participant, or permission to replay. After workspace recovery, compare task and run instructions; recovered files must not leave instructions to repair a retained sandbox. The stopped run keeps its replay hold until continuation admission. An obsolete exact-session notice retires only after terminal coordinator proof and a separate exact-run workspace hold; no new execution or file cleanup follows. |
recovery/bounded-continuation |
Use a deterministic recoverable interruption and inspect the original run/session, attempt receipts, saved result and eventual useful output. | Repeat restart/receipt delivery, race Stop or a new owner, and retain unknown external outcomes. Accepted completion/finalization recovery must not start a new provider turn or repeat its side effect. |
recovery/source-action |
Inspect active and retained actions, follow the repair owner, and resolve one eligible source-bound action with its exact ID. | Retry the settled resolution and reject a stale/foreign action. Recovery ownership alone cannot mutate the source task; inspect source status, audit and wake independently. |
recovery/exhaustion |
Exhaust or age a bounded fixture; use the currently offered retry once, then inspect its durable acknowledgement and actual continuation. | Reassign, pause, stop, close, add an unresolved dependency, or impose a budget hold before retry. The old notice must not reopen terminal work or run the wrong owner. |
recovery/workspace |
Exercise retained-file recovery, export retry, reconstruction, branch repair/reconciliation and exact-owner finalization as distinct authorized operator paths. | Use exact source/action/run/receipt bindings and preserve existing files. Reject stale source, live/uncertain writers, unsafe archives and insufficient authority. Verify actual files and accepted result separately from queued acknowledgement. |
recovery/unknown-outcome |
Inspect the provider and saved intent before recording a source-specific chat, email or governed-provider outcome. | Use performed, not-performed and unresolved cases. Wrong company/request, stale state and unauthorized resolution must fail. Unknown effects must not replay automatically. An explicit retry must record the operator’s duplicate-risk acceptance and dispatch only the authorized attempt. |
recovery/user-continuation |
Save a distinguishable instruction while Stop cleanup is pending; after verified stop, inspect exactly one eligible continuation and its useful response. | Keep the message waiting under task/ancestor pause, budget or retained-file holds. Do not impersonate a human message or infer delivery from a queued wake. |
recovery/reconnect |
Disconnect the browser, let the server change persisted task/run state, reconnect, then reload and compare. | Inspect duplicate comments/decisions and private/company boundaries after access changes. Browser transport recovery and agent execution recovery require separate results. |
source-task
Automated: recovery actions covers source scoping, bounded attempts, operator stops, quota monitoring, ownership, stale action retirement, and continuation deduplication. Recovery cards cover diagnosis, retry progress, exhaustion, and action availability. The fixture-backed execution-recovery journeys start their own test-drive instances and exercise safe, uncertain, restart, manager-lineage, and legacy-unknown paths:
pnpm exec vitest run server/src/__tests__/issue-recovery-actions.test.ts ui/src/components/IssueRecoveryActionCard.test.tsx
pnpm exec playwright test -c tests/e2e/execution-recovery/playwright.config.ts recovery.spec.ts
Manual: open a stopped task through each affected navigation path. Confirm its explanation, original owner, recovery owner if different, and next action. Follow the supported recovery until the source task produces a useful result or a specific escalation. Reload and verify that resolved notices retire and attempt history remains. A fixture pass does not qualify every live harness/provider.
The native restart integration suite also covers a prepared remote workspace interrupted before the executor's first claim. Real database tests assert one same-run bootstrap claim under concurrent controllers and reject prior claims, launch/provider evidence, and malformed workspace references. These cases prove classification, not a live remote provider restart. For that journey, interrupt a disposable deployment after workspace preparation and before its first executor claim, then confirm one provider turn starts on the original run through the normal admission gates.
The Runner transport regressions exercise a real WebSocket welcome delayed beyond two seconds. Authentication uses the ten-second connection setup budget, clipped by the current lifecycle deadline. The cases also retain failed-welcome ticket fencing, identity checks, and reconnect replay without repeated provider effects. These transport cases do not establish hosted provider acceptance.
The native provider regression sends malformed activity from a real ACPX sidecar process. It checks a structured transport error, one failed terminal, a closed session, and no provider reopening. It proves the error contract and retained failure boundary, not the cause of a historical provider outage or successful hosted task recovery.
Active remote process supervision distinguishes a failed health read from a confirmed exit. The executor tests exercise timeout and repeated gateway-failure recovery with a real listening process, unchanged ownership, and rejected identity evidence. Read-only probes use their shared deadline with bounded backoff; fast failures do not exhaust a three-attempt limit. Signal requests remain single-attempt. The Runner restart tests require positive exit evidence before replacement. The executor regressions also retire a real child during its metadata read, keep unknown adopted-process ownership held, and reject launch before detachment when Node is unavailable. The diagnostic tests cover permission failures and generation-bound zombie receipts. This coverage does not prove recovery of a historical retained sandbox or behavior during a live provider outage. The transport regression also retains a real authenticated Runner and its journal when its close probe rejects, without signalling it, checkpointing it, or starting a replacement. The failed close still retires its local connections, event timers and notification stream. Repeated close cannot report successful retirement.
For a release change during a remote provider session, verify that reattachment uses the controller's admitted pack manifest and runner digest. Check useful output from the same process without replaying a turn. Repeat with a modified sidecar, mismatched receipt scope, replacement lease, and incompatible runner protocol. The authority tests and executor wiring regressions cover selection and fail-closed scope checks. They do not prove a historical retained sandbox was recovered.
For completion recovery, restart after a native completion proposal is appended but before its session checkpoint. Verify that the original result is finalized after provider termination, with no new provider turn or repeated external action. The runtime regressions exercise the real Codex driver with a simulated transport, including a still-active provider and invalid, conflicting, duplicate, or stale proposals. This does not qualify a hosted sandbox restart.
The same database suite pauses an original preparation while recovery claims the remote run. It then verifies that the old preparation yields without opening a provider or changing the recovery owner, for both live and expired leases. Heartbeat boundary tests verify that the detachment signal transfers recovery ownership before cleanup. The suite also rejects an older unmarked preparation and verifies that calling preparation again cannot add the fencing marker from supplied profile data.
For a native workspace owner hold, repeat issue reads and recovery checks after the task becomes done or cancelled. Verify one unchanged action ID, attempt count, and timestamps; task completion must not authorize copyback. Clear only the exact receipt after operator stop verification, then confirm stale action cleanup. The route regressions and heartbeat regression cover this sequence without a live operator recovery claim.
An intentionally Done onboarding parent can still need its validated
child-completion report. Recovery must not mark that callback successful before
execution solely because the parent is Done. The existing
stale-lock sweep suite
covers delayed native/Legacy startup, invalid parent/child/company/assignee
bindings and a dead owner. Process-death and ownership backstops remain active.
Repeat the real onboarding journey and correlate callback turn events with its
reply and downloadable child file; status alone does not prove delivery. The
literal ea6c8eb5e16d61111968f633a66748b397b64a3e live failure is retained,
and the revised behavior still needs live qualification.
run-detail
Automated: run workspace recovery tests this host; it is component coverage, not an end-to-end repair.
Manual: prepare a failed run with error code workspace_validation_failed, a
linked source task, and a live workspace_validation recovery action on that
task. Open that exact run and compare its recovery diagnosis to the source task.
Use an eligible action from the run surface, return to the task,
and verify the same action state, persisted outcome, and restored execution.
Repeat with an actor who lacks authority. Verify that the run-page controls are
absent for other error codes or after the source action retires; continue other
recovery checks on the source task. Full run-detail navigation remains a manual
gap.
operator-retry
The workspace recovery regression uses the real Retry producer and a quiet delivery coordinator. It checks that a committed request starts one physical source preservation, duplicate Retry keeps the active owner's receipt valid, and startup reconstructs a resolved files-only obligation without provider replay. The execution-control lifecycle suite checks independent finalization, stored deadlines, and a bounded pass through completed obligations followed by quiet paused input. The physical export regression holds one export while another completes, then verifies a third Retry can use the free slot and shutdown joins the held work. These local checks do not prove recovery of a deployed allocation. The historical deadline case starts without preservation bookkeeping, holds the provider stop reply, and verifies that HTTP Retry cannot admit a successor until the real temporary files are restored. Duplicate requests then admit one queued turn. GitHub and Telegram admission also retain the exact pending recovery.
Automated: disposition notices tests pending/error/gated states and waiting for the real retry acknowledgement. The recovery-card suite covers workspace divergence, reissue, reconcile, and confirmation. Workspace export covers quiet restoration, legacy/operator assistance and resolved states.
For a retained legacy or native file hold, open the source task after its recovery action has resolved but its files still need recovery. The shared task projection shows actual working/backoff state or ordinary Retry. It does not show a separate infrastructure attention card. Unknown external outcomes remain fenced internally. An authorized board operator can use the resolution API to record verified files and a backup link without changing task status or starting another run. The server independently validates the original stopped-execution receipt. Agent Chat retains the hold rather than suggesting another message. The notice and repair route cover quiet live recovery, read-only access, stale or missing stop proof, source-only repair, and preserved task status. These tests use fixtures; separately verify original files and their attached artifact before recording a real repair.
For a source with a retained-file protection marker, exercise recovery through the assembled environment runtime. Its exact preservation owner may reopen the stopped allocation to read saved files; ordinary resume stays blocked. Reject a changed claim, missing stop intent, wrong lease or wrong environment before a provider call. Repeat accepted-native-result copyback for both reusable lease policies. Require the exact accepted result and completion contract; reject a rejected or unselected result, another allocation owner, and an active host writer. Verify no provider turn or wake is created, then finalize the original result once. Reject malformed or oversized Git metadata through native finalization: the run must fail and retain its file-recovery barrier, rather than successfully omitting the export. Exercise both an oversized sender file and an oversized transfer report. Verify one rejected export, no payload read after rejection, and unchanged host files. Reload a large-result run and its activity: the failure code and task recovery notice remain visible, and metadata repair offers no new provider turn. These database and filesystem controls do not qualify a deployed provider. Verify saved and newer local files, one preservation receipt, and no additional agent turn. The PostgreSQL regression covers this boundary; the opt-in provider probe also uses this runtime path with the protection marker.
For a missing managed allocation, verify a fresh Cloud-signed absence observation under the exact physical recovery owner. The existing Retry may then select an independent workspace through normal admission. Verify that the original run stays failed and missing files are not called recovered. Refuse a foreign stack, source, allocation or owner, expired signatures, changed provider organizations, permission failures and provider outages. Local PostgreSQL and signed-protocol regressions cover these boundaries; deployed recovery requires separate proof.
Repeat source-only repair with a succeeded legacy run that still has a retained
file obligation. Its result must remain successful, its current task owner and
status must stay unchanged, and later saved input must become eligible for normal
admission. A running or queued source and a normal retry of a successful turn
remain denied. The reconciliation regressions
cover these cases and stop-receipt validation without claiming live provider proof.
For an abandoned native copyback owner, the harness verifies the exact stopped
deployment and the reconciler restores saved work automatically. Task users see
no process details or shutdown form. The documented operator API handles older
receipts after independent platform verification, through a separate administrator
gate. The authorization regressions
and route regressions
cover administrator admission, ordinary-member and agent denial, suspended and
foreign membership, missing role data, and stale cloud admin rows.
The native workspace finalizer suite
runs the real reconciler with a valid saved yield from result_accepted,
workspace_finalizing, and retryable_failure. It verifies physical fencing
before verified stop, automatic and operator recovery, successful export and commitment, hold resolution,
unchanged saved results, retained approval/monitor waits, and no new provider wake.
These local regressions do not prove a deployment platform stopped a foreign writer.
Manual: reproduce an exhausted disposable action. Click once, verify pending state prevents repeated clicks, and inspect a successful continuation or an explicit rejection. Reload to confirm the durable outcome. For a workspace repair, record the compared branches/revisions and preserve uncommitted work; confirm the repair's actual result before resuming. Check the denied and stale action paths. A changed card label is insufficient proof of workspace integrity.
For graceful legacy shutdown, interrupt a disposable sandbox run while file export is in flight. Delay settlement past the first 30-second wait. Confirm the lease stays available, no repair hold or successor appears before export, and the finalizer drain waits for the same owner. After export, confirm saved files, successful lease cleanup, and one bounded continuation. Reload before checking the successor. Repeat with controller loss: the expired fence must retain the exact source and require repair, never claim restored files or start a second executor. The database-backed shutdown regression checks finalizer joining, release order, durable retry uniqueness, and reload. The settlement regressions cover other-controller fencing and owner loss. Provider boundaries are controlled in these tests; they do not qualify a live sandbox export.
For an abandoned native controller, follow the stop-verification procedure with a disposable deployment. A new platform-bound owner recovers automatically only after the harness signs proof that the exact deployment fully stopped. Legacy owners require independently verified stop evidence through the operator API; the task has no shutdown form. Confirm the original accepted result commits, the recovery hold resolves, saved files remain intact, and existing approval waits or monitor checks remain. No new agent turn should start. Repeat with a retry-phase owner and an ordinary runtime manager; the first can resume through automatic proof or authorized operator confirmation, while the second cannot use the operator API.
post-stop-message
Automated: legacy continuation, queue routes, and native restart recovery cover their respective recovery paths. Legacy failure continuation adds a browser journey; it is not native runtime proof.
Queued Stop database regressions verify that an operator cancellation before runtime selection releases its own locks, preserves deferred input without launching it, and leaves another active cycle of the same routine unchanged. Provider cancellations and already selected or dispatched runs retain their existing release behavior.
Manual: stop a disposable run, submit a distinguishable follow-up, and observe any cleanup wait. After confirmed stop, verify the follow-up reaches one eligible continuation and produces the requested answer. Repeat with a task/ancestor pause and a budget hold: recovery must not bypass the gate. For unknown external outcomes, inspect the provider before authorizing another operation.
browser-reconnect
Automated: live-update recovery covers client transport recovery with mocks. It does not prove runner restart.
Manual: go offline during a disposable run, let the server reach a new state, then reconnect. Confirm task/run/attention data refresh without duplicate comments or decisions; reload and compare. A healthy websocket proves transport only. Separately inspect the underlying execution if it is still stuck.
Gotchas
- Legacy and native runtimes have different ownership and restart paths. Record which one was exercised instead of inferring coverage from the adapter name.
- A process disappearance, elapsed timeout, or successful API retry does not prove an external tool operation never happened. Unknown outcomes stay unknown until corroborated; automatic replay can duplicate a side effect.
- Active-run watchdogs, task watchdogs, reviewers, and recovery owners have different authority. No recovery card grants board permission by itself.
- Idle Agent Chat is not stranded work. An intentional operator stop must not silently trigger recovery that fights the user's instruction.
- Source inspection and mocked component tests do not qualify real server restart continuity. Use the appropriate runtime suite for that claim.
- See execution semantics for the governing recovery contract and steering for saved follow-ups.
