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.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools and code
execution. The runtime does not expose a more specific model ID or
context-window size.

## Thinking Path

> - Paperclip manages agents and their execution authority.
> - A plugin can host Runner tasks on a persistent execution host.
> - Admission checks must observe current lifecycle state and
credentials.
> - The current runtime reader also resolves files, skills, and
connections for each check.
> - Some providers also repeat the same project authentication check
during submit.
> - This pull request adds a compact fresh reader and an explicit
submit-time validation contract.
> - Providers can remove repeated work while Core keeps lease and scope
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 e5351b240a Verify native Runner setup through plugin tasks (#17029)
## Thinking Path

> - Paperclip manages work for AI agents.
> - An environment plugin can own a Runner task.
> - The merged launch-preparation contract lets the execution owner
build the provider configuration.
> - Core still needs a task process owner and a setup test that uses
that configuration.
> - This PR connects the task API to the Runner process-owner contract.
> - Operators can test a plugin environment before Core sends it task
work.

## Linked Issues or Issue Description

**Subsystem affected**

Runner, plugin SDK, and agent environment tests.

**Problem or motivation**

A task-only environment cannot use the shell-based setup path. Core must
verify the Runner hello exchange and process cleanup through dedicated
task operations.

**Proposed solution**

Add a lease-bound task driver and use it for a bounded setup probe. Keep
heartbeat admission and task execution in #16978. This PR follows the
merged launch-preparation contract in #16997.

**Alternatives considered**

A provider declaration alone cannot prove that Runner and the provider
connect. A shell bridge would give the plugin an unnecessary command
interface.

## What Changed

- Pass structured Runner launch data to process owners. Support an
external connection and explicit detach.
- Add typed launch authentication checks and checkpoint operations.
Check lease, run, project, and retained-task authority.
- Connect launch preparation, PRP, termination proof, and credential
handoff to the task driver. Reject local environment overrides during
installed-account setup. Pass saved-account identity and credential home
directly from Core.
- Run a short-lived setup probe through the existing agent environment
test API. Require a verified provider hello and cleanup. Keep saved
Copilot account checks metadata-only through a dedicated task operation.
- Update the Copilot source identity because the shared transport source
changed. Keep provider behavior and the earlier identity fixture.

## Verification

- CI passes on `f987adec7`: 55 successful checks and 5 expected skips.
Standard Greptile and Apex are both 5/5 with no open findings. The
branch merges cleanly with current master.
- Repository typecheck and build pass after the rebase onto the
workspace-provider contract. Server typecheck and build also pass after
the final setup fix.
- The 110 focused lease, SDK, setup, Copilot, and route cases pass after
the rebase. All 14 setup cases pass after the final change. These
include a real local Runner with a test provider. The saved-agent
model-discovery case also passes.
- Apex found that Core's relative workspace marker failed the driver
path check, and non-Codex sessions omitted the observed model. Both
failures were reproduced and fixed. The probe leaves physical workspace
selection to plugin preparation. The transport reads each provider's
observed model and exposes it to the driver. All 14 setup cases, 6
transport peer cases, and both existing real Runner/OpenCode cases pass.
Runner build and server typecheck pass.
- The coverage audit removed two redundant cases, repeated fixture code,
and two extra real Runner launches. It kept authorization, credential
selection, cancellation, lost replies, termination proof, checkpoint
identity, and provider setup checks.
- The Copilot source-identity check passes. The added-line secret and
PII scan passes. The unmerged v52 attestation was regenerated after the
shared transport fix.
- CI on `13faeff02` caught one stale Copilot digest assertion after
attestation regeneration. The literal now matches the candidate
attestation, and all 49 installation cases pass. That CI lane otherwise
passed 1,818 cases.
- An earlier CI run hit an unchanged UI toast timing test. The separate
fix is tracked in #16952. Current CI passes that shard. CI also caught a
stale model-discovery assertion in this change; the assertion is fixed.
- The local full-suite run was stopped when master changed. The final CI
run supplies exact-head full-suite validation. No live Cloud or provider
test was run.

## Risks

- Native hello tests require a saved Core account or the installed
account. Local environment overrides are unsupported for
installed-account probes and fail before the provider runs.
- A native task provider must declare launch preparation and
authentication-check version 1. It must keep the checked configuration
fixed through submission. Core rejects providers that cannot make this
guarantee.
- A lost task reply does not prove process termination. Core retains
grants until the provider proves termination and Core saves required
state.
- This PR does not enable native heartbeat dispatch through plugin
environments. Cloud deployment and live provider validation remain
separate.

## Model Used

OpenAI Codex, GPT-6. The exact model ID and context window are not
exposed in this session. Tool use includes code editing, local tests,
and the GitHub CLI.
