DottaandPaperclip 09ad9adce2 feat(server): adopt running remote agents through durable controller checkpoints (#17439)
## Thinking Path

> - Paperclip must keep admitted remote work alive while its main server
is replaced.
> - Runner owns recovery mechanics and exposes opaque checkpoints
through #17097.
> - The server owns company scope, encryption, Stop, tool authority and
execution ownership.
> - A successor must prove current ownership before it adopts the
original execution.
> - Checkpoint bursts must also leave capacity for normal requests and
lease renewal.
> - This PR persists and adopts that authority through the existing
runtime boundaries.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Remote agents retain the original execution during a bounded main-server
outage.

**Current behavior**

A server restart can lose the controller's local state and connection.
An unsafe replacement could repeat a turn or an uncertain mutation.
Checkpoint writes in the request pool can also delay ordinary requests
during an aligned burst.

**Proposed behavior**

Restore encrypted control records from Postgres and adopt the original
runner under a fenced lease. Recover known tool receipts through current
tool authority. Give control checkpoints a shared pool capped at two
connections per database owner.

Depends on #17097. Successors are #17455 and #17456. Qualification and
presentation remain separate review slices.

## What Changed

- Add company/run-bound encrypted checkpoint records and migration 0394.
Keep the SQL idempotent after renumbering against current master.
- Recover startup and expired ownership through native runtime and
heartbeat. Preserve the sandbox lease, admitted runner artifact, harness
configuration, native session and active turn.
- Keep Stop, finalization, preparation ownership and stale-writer
fencing transactional. Preserve graceful detach and natural crash
takeover.
- Recover committed tool receipts through the existing authority.
Reauthorize reads and hold uncertain mutations.
- Bound startup retention with the existing coordinator and preserve
zero idle scans.
- Share at most two checkpoint connections per database client. Keep
application and liveness capacity separate. Close the checkpoint pool
during shutdown; late writes cannot reopen it.
- Count SQL across both application and checkpoint clients. Prove
request/liveness progress, command recovery and failure after pool
shutdown with real Postgres.

## Verification

Project creation recovery now uses the existing project activity receipt
owner. It retains authenticated input normalization, fingerprint checks
and current run authority after the receipt lock. An absent receipt
returns no result before mutation. The new lost-HTTP-response and
no-effect regression uses real API routes and Postgres. The seven
transport cases pass locally. This Mac skips all 20 database cases. On
current source `5de803c2cd`, Linux [job
122593415890](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415890)
executes all 20 project-tool cases successfully (9.480 seconds),
including the committed-project lost-response regression. Its shard
passes 1,627 cases with three unrelated skips. Server typecheck passes.
The transport regression initially has two failures; a subsequent
incorrect expectation about schema defaults was corrected before the
final pass. Ordinary execution adds no checkpoint writes or recurring
work.

Current candidate `5de803c2cd` includes the project-creation receipt
recovery fix and master `2cd747d1b6`. Migration 0394 retains the prior
idempotent checkpoint DDL. Every master SQL file and journal entry is
preserved. Snapshots 0390–0394, migration checks and server typecheck
pass.

The ordinary warm-turn regression fails on its second turn before
`a219ab51ad`. After correction, three completed warm turns select the
correct prior checkpoint and preserve the original session. All 288
provider-wiring cases pass. The control plane, external persistence
callback, identity rotation and filesystem are real; the backend and
database-load seam are scripted. The 13 warm admission/configuration
variants also pass after final master integration. This does not qualify
an underlying harness.

At current source `5de803c2cd`, Linux [job
122593415907](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415907)
passes all 940 native-session-executor cases (61.431 seconds), including
the warm external-checkpoint behavior; the shard passes 2,358 cases with
one skip. Current [Runner job
122593415475](https://github.com/paperclipai/paperclip/actions/runs/40620576702/job/122593415475)
passes the native recovery lane: 115 passes and five container-only
skips, including the encrypted restore guard, fresh preparation (63.189
seconds), blocked claim lock (1.226 seconds) and recovery beyond 101
blocked owners (3.897 seconds). The first lane passes 2,215 cases with
one skip. The SQL cost test reports zero idle and streaming SQL for both
output volumes; this is component evidence, not a production capacity
claim. At prior candidate `1ff7bb44f4`, Linux job 122549307215 passes
all 938 native-executor cases, including the three-turn
external-checkpoint regression. Job 122549306469 passes the native
recovery lane with 115 passes and five container-only skips, including
the encrypted-restore session guard, fresh preparation (63.664 seconds),
claim-lock contention (3.961 seconds), and 101-owner recovery (3.824
seconds). This Mac skips the real-Postgres suite. The earlier full local
executor attempt has 921 passes and 16 failures during embedded-Postgres
initialization before assertions. The original fixture collisions and
their corrections remain recorded.

At earlier candidate `8fbe62b41d`, server shard job 122535673841 has
3,876 passes, one failure and one skip in an unchanged expiry-worker
retry/drain timing test. The same server/database tree on qualification
source `b64cac6951` passes all 20 expiry cases and all 3,877 shard
cases. The single diagnostic retry, job 122541891915, passes all 20
expiry cases and all 3,877 shard cases (one skip). No assertion was
weakened. The original failure remains recorded and its exact timing
race is not proven. All Actions checks and legacy status passed on
`8fbe62b41d`, with completed Greptile 5/5 and no open feedback. The next
candidate `1ff7bb44f4` also passed all Actions checks and Greptile 5/5.
Its Paperclip Review remained queued before the new master conflict
required integration. The new candidate needs fresh exact-head CI and
reviews; old checks do not qualify it. Migration generation is
checkpoint-only, all master SQL and journal entries remain unchanged,
and migration checks, server typecheck and all 13 warm-owner variants
pass after integration. The first migration check was blocked by TSX
sandbox IPC; its permitted repeat passes. The first warm-test command
used an incorrect path and ran no tests; the corrected command supplies
the 13-case receipt.

All 16 database pool-lifetime/options/teardown cases pass after granting
loopback permission; the first batch had two EPERM failures and 14
passes. Earlier semantic-tool/HTTP recovery, adoption, encryption-batch,
zero-streaming-write and idle-SQL receipts remain source-attributed in
the [qualification
record](https://github.com/paperclipai/paperclip/blob/2ff66f57da0da35bac1c19a2366ea4b84d87a986/doc/plans/2026-10-22-hot-upgrade-qualification.md).
That record retains earlier assertion, setup and cleanup failures and
their corrections. No failed gate is waived.

The historical 300-session component campaign passes four after phases:
steady read p99 is 107–108 ms at 500 reads/s and 100 writes/s;
aligned-burst read p99 is 103–105 ms after the bounded pool, versus
584–689 ms before. This comparison isolates the persistence corrections.
It does not measure the final stack's hosted active-agent capacity. The
hosted zero-agent API pair leaves SQL and CPU essentially unchanged, but
both arms fail absolute latency gates and candidate peak cgroup memory
fails its gate. The active-agent/viewer matrix, different-artifact
upgrade and rollback remain open.

Run `PAPERCLIP_TEST_DATABASE_URL=<owned-disposable-postgres> pnpm
--filter @paperclipai/server exec vitest run
src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`.

Previous head `f2db8a6568` had one failed workspace setup gate: [job
122555672441](https://github.com/paperclipai/paperclip/actions/runs/40608984238/job/122555672441)
passes all 4,169 UI tests and 285 CLI cases (one skip), but the company
import/export suite reaches its 30-second health deadline during doctor
startup. Its output does not reach the server-start step. The CLI,
server, database, shared, adapter and plugin trees are identical on
qualification source `a866619d7b`, whose [job
122555886663](https://github.com/paperclipai/paperclip/actions/runs/40609057937/job/122555886663)
passes that fixture and all 286 CLI cases. The one diagnostic retry,
[job
122561057225](https://github.com/paperclipai/paperclip/actions/runs/40608984238/job/122561057225),
passes the formerly failing fixture and all 286 CLI cases. All Actions
checks and legacy status on `f2db8a6568` pass. Its exact-head Greptile
completed at 5/5 with no open feedback. The current integrated head
requires fresh checks and a completed Paperclip Review before merge. The
original failure remains recorded; its exact timing cause is unproven. A
repeated failure requires investigation and repair rather than another
retry.

All current-head CI, legacy status, exact-head completed Greptile 5/5,
resolved feedback and ordinary GitHub merge eligibility remain required
before merge.

The latest integration preserves master’s published Copilot v70 profiles
and every published migration. Checkpoint migration
`0394_conscious_whizzer.sql` was generated with `pnpm db:generate` and
retains the prior idempotent DDL. The Runner vendor rebuild and replay
parity checks pass. Server typecheck and all 13 warm-owner variants pass
after that rebuild. The imported report-lock patch is byte-identical to
master; its intentional patch-context whitespace is retained, and the
feature delta passes whitespace checks. No hosted experiment was run.

## Risks

The pool adds up to two active connections per instance, shared across
agents. Checkpoint delivery can wait behind that bound; it still
requires its commit. Steady component-test Postgres CPU rises by about
1.7 percentage points of a two-CPU allocation. These corrections do not
remove the stack's control and renewal writes. The migration and key
must survive replacement. Fresh-database tests and local load do not
establish different-artifact hosted upgrade or rollback continuity.

> - Admission checks must observe current lifecycle state and
credentials.
> - The current runtime reader also resolves files, skills, and
connections for each check.

checks.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

Plugin Runner startup before task submission.

**Current behavior**

One measured startup made 30 full runtime reads during bootstrap. These
reads took 5.759 seconds. Each guard can resolve instructions, skills,
and connection assignments even when it only needs current identity and
lifecycle state. Providers that already enforce project authentication
in submit must also perform a separate Core preflight.

**Proposed behavior**

Use a lifecycle-owned runtime identity reader for guards. Keep the full
runtime reader for synchronization inputs. A trusted provider can
declare `projectAuthCheckAtSubmit: true` in its prepared result. Core
pins the exact configuration, provider, and project set on the lease.
The provider must reject authentication conflicts before credential
installation or task start. Providers that omit the flag retain the
existing preflight.

**Reason and benefit**

Estimated savings with a paired consumer: 4–5 seconds from compact
runtime checks, plus roughly 0.5–0.9 seconds from removing the duplicate
authentication operation. These estimates overlap and are not a measured
deployed result. Refs #17367 for the separate run-log HEAD optimization;
this PR does not duplicate it.

**Breaking changes**

No migration. The SDK adds a host method and an optional prepared-result
field. Consumers that use them require this Core host version. Older
providers retain their existing flow.

## What Changed

- Add `agents.getRuntimeIdentity` across SDK, RPC, host service, and
test fixtures.
- Reuse the existing company, plugin ownership, readiness, and
capability checks. Read lifecycle state and protected instance secrets
fresh on every call.
- Skip instruction, organization, skill, and connection hydration in the
compact reader.
- Allow explicit submit-time authentication enforcement, with prepared
scope pinned and checked again at dispatch.
- Emit fixed preparation, project-auth, submit, and connection timing
phases.

## Verification

- 72 targeted SDK capability, plugin task-owner, and environment-task
mediator tests passed.
- 33 real embedded-Postgres lifecycle and secret tests passed, including
pause, content revision, company isolation, plugin disablement, and
secret rotation.
- SDK and server TypeScript checks passed. Local Runner/eval TypeScript
outputs were built to satisfy server type resolution.
- Local Postgres required missing library aliases in ignored
dependencies; no product source was changed for that repair.
- Full repository suites are delegated to GitHub CI. No live rollout or
speedup claim.

## Risks

The submit-time flag delegates enforcement to a trusted provider. It is
not proof that prepare already checked authentication. The provider must
check before VM credential installation or task admission. Core still
checks exact prepared scope, active lease, run identity, credential
type, and dispatch fencing. Existing providers keep the separate check.
Roll back a paired consumer before rolling back this host.

## Model Used

OpenAI GPT-6 (Codex), with code execution and repository tools. Exact
deployment build and context-window size are not exposed.

Nicky LeachandPaperclip a708a13336 Separate plugin workspace completion from maintenance inspection (#17329)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Storage plugins own remote task workspaces.
> - Run completion currently requests the same inspection used for
storage cleanup.
> - That inspection can fetch remote refs and scan files after the agent
has finished.
> - Completion needs retained workspace identity and durable writes, not
permission to delete files.
> - This change adds an optional completion operation and keeps
maintenance inspection separate.

## Linked Issues or Issue Description

**What happened?**

A successful plugin-backed run can fail during completion because the
storage provider performs a slow remote-recoverability inspection. Dirty
or unpublished output does not need a deletion-safety proof to remain
valid task output.

**Expected behavior**

Completion verifies the assigned workspace and confirms durable writes
through the provider. Cleanup still requires the existing full
inspection.

**Steps to reproduce**

Run a task with plugin-owned storage whose inspection fetches remote
refs. Let the agent finish, then observe completion waiting for the
maintenance inspection.

Related context: #16428 added finalization observability. The duplicate
search found no existing PR for this provider contract.

## What Changed

- Add optional `workspaceProvider.finalizationVersion: 1` and strict
`finalize` / `finalized` schemas.
- Pass original run and agent context through live completion and
recovered completion.
- Give the new operation a 30-second deadline and keep ownership checks
and lifecycle serialization.
- Retain the inspection fallback for providers without the capability.
Keep maintenance inspection and removal unchanged.

## Verification

- SDK build passed.
- Targeted SDK and completion unit tests: 7 passed.
- Added integration coverage for capability selection, legacy fallback,
maintenance separation, and failure propagation.
- Local integration setup timed out starting PostgreSQL; the integration
suite passed in GitHub CI.
- Full build/typecheck and broader tests passed in GitHub CI (55
successful checks, 2 skipped). Local checks remained targeted as
requested.
- Diff reviewed for secrets and operational identifiers.

## Risks

The capability is opt-in. Providers must not advertise it until their
completion implementation is available. An unavailable provider or
failed durability barrier remains retryable. No schema or stored-binding
migration is required.

Test-file size exception: the provider integration suite grows from 973
to 1,002 lines. The 29-line case follows the same prepared binding
through legacy completion, opted-in completion, and maintenance
inspection using the existing single-connection database fixture.
Keeping it there avoids a second embedded-Postgres lifecycle for one
transition test. The completion helper unit tests are in a separate
focused file.

## Model Used

OpenAI GPT-6 Codex, with reasoning and code/test tools.

Nicky LeachandPaperclip 00331e0254 Connect native Runner admission to plugin-owned workspaces (#16978)
## Thinking Path

> - Paperclip manages work for AI agents.
> - A plugin can own an execution environment and its files.
> - #17029 supplies the task driver and bounded setup verification.
> - Heartbeat still prepares workspace files on Core and expects a shell
transport.
> - This PR gives the selected plugin ownership of workspace preparation
and native task execution.
> - Core keeps admission, tool authority, and recovery checks.

## Linked Issues or Issue Description

**Subsystem affected**

Heartbeat workspace admission and native Runner execution.

**Problem or motivation**

A task-only plugin cannot run through Core filesystem staging or shell
execution. Native admission and recovery must use the same lease and
workspace ownership.

**Proposed solution**

Use the task driver from #17029. Resolve workspace and project
identities without Core file operations. Connect native dispatch and
restart recovery to that driver.

**Alternatives considered**

Keep workspace admission and dispatch in one change. A workspace change
alone would leave dispatch on the previous transport. An execution
change alone would leave Core staging files for the wrong host.

## What Changed

- Enable plugin environment selection for native workspace sessions.
- Resolve workspace metadata and authorized project references without
Core checkout, copy, or provision operations.
- Preserve agent-default and primary workspace policies. Use the pinned
workspace provider for plugin-backed project storage. Reject unsupported
Core service commands and cross-owner reuse.
- Connect native execution to the prepared task driver. Keep assigned
MCP authority on Core.
- Save exact checkpoint identity, transfer selected account refreshes,
and require termination proof before replacement or cleanup.
- Complete managed plugin workspaces through their storage provider. Use
the same check after a restart. Keep branch validation and leave
task-owned files on the plugin.
- Include default instruction content in runtime synchronization when no
instruction directory exists.
- Defer new-agent Copilot verification until the saved-agent lifecycle
can acquire the agent-owned computer.

## Verification

- Rebased onto `origin/master` at `898144f4b3`. Master advanced once
during verification. Both manual conflicts joined import blocks: one in
`native-session-executor.ts`, and one in
`heartbeat/runtime-execution.ts`. The seven patches retain their logic.
The first rebased head passed repository typecheck, build, all 862
focused execution/finalizer cases, and all CI gates. The latest head
`93e5a72892` passes server typecheck and all 880 focused execution,
finalization, and execution-control notification tests. All 54 CI/review
checks pass, with two expected skips. Greptile ran automatically and
scored this head 5/5 with no unresolved findings. No new review or Apex
request was made for these import-only resolutions.
- The successful CI workflow initially left three stale job-check
reports. Targeted policy and summary reruns cleared the reports. No
source change or test fix was needed.
- Repository typecheck and build pass: `pnpm -r typecheck` and `pnpm
build`.
- Focused native execution and restart tests pass: 795 cases. The
account and harness suites pass: 159 cases. Workspace admission passes:
48 cases. The SDK task lifecycle, workspace API, runtime-hook, and
instruction checks also pass.
- The heartbeat integration case uses the merged workspace provider
contract and reaches native dispatch with no project files on Core. The
new-agent case confirms that creation leaves the agent in `preparing`
until lifecycle verification.
- Map validation and the Copilot source-identity check pass. No Runner
implementation or source-identity bump is in this PR.
- The first rebased workspace run found two stale path assertions and a
recovery guard that did not recognize task-owned targets. These are
fixed. The storage integration fixture also needed its persisted source
binding; the production authorization check stays in place.
- Two prior review findings required rejection of Core service startup
and cross-owner workspace reuse. The existing admission fixtures now
check both failures. The installed-account authentication finding was
fixed in merged #17029.
- Tests reuse the current fixtures. No new provider test matrix or live
Runner process is added for these fixes.
- The prior head `2db273ec12` passed CI on its first attempt and reached
standard Greptile 5/5. Apex scored 4/5 and found local-folder checks
during plugin completion and recovery.
- The completion fix reproduces both failures. It passes all 110 cases
in the runtime execution, workspace finalizer, and workspace provider
integration suites. Server typecheck and map checks pass. CI passed on
`62d8335b4e` on its first attempt, and standard Greptile scored 5/5. The
next Apex review scored 4/5. It found that a failed plugin inspection
could abort restart recovery.
- The restart fix records a failed workspace receipt and uses the
current run retry policy. A regression first reproduced the aborted
pass. It now checks retry state, retained results, and completion of
another workspace in the same pass. All 68 finalizer cases and server
typecheck pass. CI passed on `7d4016323b` on its first attempt. Standard
Greptile and Apex both scored 5/5. Apex left one P2 about lost failure
codes.
- The diagnostic fix keeps the known branch and owner mismatch codes in
receipts and run recovery state. It gives repair guidance for those
codes and keeps unknown plugin errors generic. All 96 affected finalizer
cases and server typecheck pass. Before the rebase, required CI passed
on `c2fa61c6c8` on its first attempt. Standard Greptile and Apex both
scored 5/5 on that head, with no unresolved findings. The new head
retains these reviewed patches.
- The earlier Superagent scan on `c2fa61c6c8` was inconclusive after a
pinned merge-base checkout failed or timed out. The current scan on
`93e5a72892` passes.
- The exact rebased head passes all 48 workspace cases and server
typecheck. The first local test launch could not bind PostgreSQL inside
the sandbox. The authorized local-server run passed.
- The prior head reached standard Greptile 5/5. Its first CI run hit an
unchanged Runner cleanup timeout and an external build-runner shutdown.
Both jobs passed on the single retry. The timeout cause is not
established.
- A local regression check found that a retained Core workspace could
also enter a plugin task without file transfer. Core now rejects this
move before provider work. The existing ledger test covers both
directions and confirms that the source files stay intact.
- The first active standard review scored 4/5. It found that a fresh
plugin retry could enter Core Git preparation. This mode now uses the
existing unsupported-storage error before workspace resolution or
acquisition. Both unsupported-mode cases pass, and server typecheck
passes.
- No live Cloud or provider validation was run.

## Risks

- The prerequisite #17029 is merged. This PR targets master.
- Native plugin tasks support per-turn workspace sessions. Core service
commands and fresh retries that import retained files remain
unsupported. A workspace storage plugin can use the modes and strategies
it declares.
- Core-managed credentials support Codex and direct Claude accounts.
Other managed credential routes fail closed. Other harnesses can use an
installed account.
- A provider must preserve its prepared configuration and report process
termination correctly. Uncertain termination keeps the task pending
cleanup.
- Cloud deployment and live provider validation remain separate.
