DottaandPaperclip 006d5691a6 feat(server): support volume-free web server handoff (#18518)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Its web server also owns controller admission and user commands.
> - A rolling deployment starts a replacement before the old server
exits.
> - Shared database state alone does not preserve local agent files,
browser chunks, or in-process commands.
> - This pull request adds an opt-in ephemeral server contract and a
local overlap test.
> - The benefit is a web server that can relinquish traffic and local
files without losing acknowledged work.

## Linked Issues or Issue Description

Refs #18403, #18327, #18335, #18341.

**Current behavior**

The control-plane web server still has local agent-file authority and
local command targets. A new container can miss saved bytes or send a
command to the wrong process. An existing browser tab also needs chunks
from its original build.

**Proposed behavior**

Eligible servers share only PostgreSQL, object storage and stable
secrets. A replacement waits for readiness. The old server drains
admitted requests, keeps owner commands available through handoff, and
releases controller leases. Explicit maintenance adopts existing files
before the volume is removed.

**Reason and benefit**

This is the application prerequisite for rolling app-only deployments.
Schema migrations and permanent multi-replica operation are outside this
change.

## What Changed

- Store agent-file manifests in PostgreSQL and immutable bytes in S3.
Treat local roots as disposable projections. Preserve existing
permission checks and edit conflicts.
- Add an explicit migration, eligibility and object-retention command to
the production runtime bundle.
- Add `/api/ready`, admitted-request drain, browser restart signaling
and retained immutable UI chunks.
- Carry transaction-aware work hints across controllers during handoff
and active execution. Keep listeners closed when idle.
- Deliver durable Stop and runtime responses to the execution owner.
Recheck request lifecycle and access before response dispatch.
- Reject local-only configuration in ephemeral mode. Keep the feature
disabled for existing installations by default.
- Add an isolated PostgreSQL/S3/proxy/browser deployment harness with
independent server homes and retained failure evidence.

## Verification

- All CI checks pass on `ce17b95019d3cf1cabd357d19b6d37f96782cc5c`:
workspace typecheck, build, Runner checks, server/general tests and
browser shards. Greptile reviewed the runtime changes at 5/5 with all
findings resolved; the final commit updates maps and the plan.
- Local targeted checks passed: coordinator 27; Stop/recovery 33;
PostgreSQL command delivery 6; route/workspace regressions 8; bootstrap
Stop 1; restart recovery 75. PostgreSQL command tests simulate the
provider edge.
- Local browser proof passed 91 reads and 19 saves; reconnect took
1,013ms. The tab opened Audit from S3 after deletion of A's whole
home/build. This uses compiled workspace code and local-trusted auth,
not released containers or live agents.
- Local workspace typecheck/build passed; current server and runtime
bundle passed. The earlier broad local suite was stopped after three
hours and is not a passing receipt. Its retained failures and isolated
reruns are documented in the plan.
- Stacked #18526 adds stricter graceful-exit proof, an unready
replacement control, live Runner qualification and a Stop handoff
correction. Hosted enablement remains gated on those results and Cloud
#1096. No hosted stack has been enabled.

## Risks

- Apply migration 0422 before enabling the feature. Existing data must
pass each owner's migration and eligibility checks. Do not discard a
volume based on a single migration page.
- Durable manifests remain authoritative after the opt-in is disabled.
Rolling back to a binary that ignores them is unsupported.
- Cold directory restoration and complete shutdown timing still need
qualification before enabling a hosted stack.
- Retained UI assets must cover the supported browser and rollback
window. Cleanup is explicit; no new idle maintenance polling is
introduced.
- This change does not claim production zero downtime or authorize a
fleet-wide enablement.

## Model Used

OpenAI Codex, GPT-6 family. The exact serving model ID and
context-window limit are not exposed in this session. Used reasoning,
code editing, shell execution and browser automation.

cafa25029c fix(native-runtime): recover unclaimed remote startup (#16349)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - The native runtime preserves task execution across server restarts.
> - Remote workspace preparation can finish before the executor claims
its first provider attempt.
> - The recovery classifier required a provider checkpoint even when the
durable coordinator proved that execution had never started.
> - A deployment during this interval therefore left safe startup work
on a permanent recovery hold.
> - This pull request admits that narrow startup state to the existing
same-run bootstrap path. Existing execution and ownership checks remain
in force.
> - The original preparation yields when recovery owns the coordinator.
It cannot fail or clean up the recovered run.
> - Tasks can continue after this interruption without an operator retry
or a duplicate provider turn.

## Linked Issues or Issue Description

**What happened?**

A server deployment interrupted a prepared remote workspace before the
native executor's first claim. The coordinator had attempt zero,
controller generation zero, and no owner, process, provider event, or
checkpoint. Restart classification returned
`ambiguous_remote_recovery_evidence` and blocked the task.

**Expected behavior**

The server should recognize this durable never-claimed state and
continue the original run through normal execution admission. A prior
claim, uncertain ownership, or contradictory execution evidence must
retain the recovery hold.

**Steps to reproduce**

1. Prepare a remote workspace for a native run.
2. Stop the controller before the executor commits its first claim.
3. Restart the controller and classify the running native task.
4. Observe that the old classifier blocks it because no provider
checkpoint exists.

Related: #16341 preserves remote recovery failure reasons. #16344
strengthens remote restart qualification. Neither changes admission for
an untouched remote startup.

## What Changed

- Require a server-owned fencing version written only with fresh native
identities. Older unmarked preparations stay held during rolling
upgrades; caller profile data cannot add that marker to an existing run.
- Leave the current server's active preparation with its existing
execution.
- Yield through the controller-detachment path when a different
execution owns the coordinator lease. Lease expiry does not grant
takeover authority.
- Preserve run-scoped gateway tokens during detachment so stale
preparation cannot revoke the recovered worker's tools.
- Admit a valid prepared remote workspace only when the locked
coordinator proves attempt and controller generation zero, no owner, and
no prior session or execution evidence.
- Check launch receipts and provider source events before granting
bootstrap recovery.
- Keep the original run and session. Preserve atomic recovery claims,
executor durable-state checks, and normal admission gates.
- Add real PostgreSQL regression tests for competing controllers and
seven contradictory evidence cases.
- Update recovery documentation, the run-log reason, and both capability
maps.

## Verification

- The competing-controller regressions failed before the ownership fix
and pass for both live and expired foreign leases.
- On the final revision, 77 runtime-selection, restart recovery, real
PostgreSQL, and heartbeat boundary tests pass with no skips, including
all local runner process fixtures. The full native executor file passes
all 698 tests.
- Another 91 live-run route tests pass locally. An earlier CI timeout in
that unrelated file passed on retry; the complete final-head CI passed
without that failure.
- `pnpm -r typecheck`, `pnpm build`, `node scripts/check-maps.mjs`, and
`git diff --check`: passed locally. The map check verifies structure
only.
- Local `pnpm test:run` did not finish: an early attempt had
build-related collection failures, and later full-suite execution was
stopped after complete CI passed. Targeted suites passed after build
preparation. This is not a local full-suite pass.
- The complete [PR
workflow](https://github.com/paperclipai/paperclip/actions/runs/38669996667)
passed on `2baffb3652bfeb4705a30ca3706fbda6c3d72aa4`, including all test
shards, build/typecheck, runner verification, and browser E2E. All 55
applicable review/security/CI checks succeeded; two Storybook checks
were skipped.
- [Greptile
Apex](https://github.com/paperclipai/paperclip/pull/16349#issuecomment-6180848957):
5/5 on the same final head, with no unresolved findings.
- No live remote provider restart is claimed by the database regression.

## Risks

- A bare executor can no longer take a foreign coordinator lease after
expiry. A verified recovery claim must transfer authority first.
- Existing preparations without the server-owned fencing marker retain
their recovery hold during rolling upgrades.
- Incorrect admission could duplicate provider work. This path requires
a positive durable never-claimed receipt, rejects contradictory launch
evidence, and keeps the executor's existing durable-root verification.
- Previously claimed or incomplete remote recovery evidence remains
blocked. This change does not clear historical terminal holds.
- No schema, API, dependency, or UI changes.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, tool use, code execution,
and browser inspection. The exact serving snapshot ID and context window
size are not exposed in this session.
