## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Claude local adapter supports subscription login through a
sandbox
> - The new-agent page must show login before the user creates an agent
> - Test results must not expose raw sandbox diagnostics or secret
values
> - This pull request adds the login UI to both Test lanes and closes
the diagnostic boundary
> - The branch also adds durable cleanup recovery for failed sandbox
teardown
> - Reusable sandboxes must retain both their recorded teardown
configuration and a valid lifecycle path until destruction succeeds
> - The benefit is a usable login flow with fixed public checks,
redacted server logs, and recoverable sandbox cleanup

Related public work:
[#9488](https://github.com/paperclipai/paperclip/pull/9488) adds
first-class recognition for `CLAUDE_CODE_OAUTH_TOKEN` in headless and
remote runs. Related public issue:
[#2681](https://github.com/paperclipai/paperclip/issues/2681) requests
Claude Code subscription support. This pull request adds the login
transport and new-agent UI flow that those changes do not provide.
**Subsystem affected:** Claude local adapter, server login probes,
sandbox provider setup, cleanup recovery, and the new-agent UI.
**Problem or motivation:** The Test lanes did not show the sandbox login
panel in all supported cases. Test results also exposed raw probe
diagnostics, and JSON escapes could end secret redaction early.
**Proposed solution:** Surface the login capability through the bundled
provider manifest. Prepare the same probe runtime in the ACP lane. Send
diagnostics only to redacted server logs. Keep Test checks on fixed
public messages. Normalize login URL hints to allowlisted HTTPS Claude
and Anthropic hosts. Consume JSON escapes during redaction. Preserve
failed sandbox cleanup state across retries and restarts, and prevent
deletion from severing the lifecycle context of a live reusable sandbox.
**Alternatives considered:** Keep raw diagnostics in Test checks or
trust login URL text from the sandbox. Both choices increase information
exposure. Keep separate probe behavior in the ACP lane. That choice
would leave the two Test lanes inconsistent.
## What Changed
- Surface the sandbox login panel on both Test lanes.
- Reconcile the bundled Daytona plugin manifest so
`supportsSetupTokenLogin` reaches the UI capability gate.
- Prepare the ACP Test lane with the same probe runtime as the CLI Test
lane.
- Add the `claude_acp_login_probe_unavailable` warning when the ACP
probe cannot run.
- Send raw sandbox diagnostics only to redacted server logs.
- Keep Test checks on fixed public messages in the ACP, managed-config,
and CLI paths.
- Normalize login URL hints to allowlisted HTTPS Claude and Anthropic
hosts.
- Redact JSON and escaped-JSON secret values, including escaped quotes
and backslashes.
- Preserve orphan cleanup records across provider failures, restarts,
and unavailable plugins.
- Atomically block environment deletion while a live reusable sandbox
lease still depends on it.
- Verify pending cleanup destroys plugin sandboxes with the provider
configuration recorded on the lease, even after the current environment
configuration changes.
## Verification
- Head under review: `506b7fa2d83c36bfa5fd722ee9d95b0c7431c241`.
- Focused environment route/service/runtime coverage passes: 196 tests
across 3 files.
- `pnpm -r typecheck` passes.
- `pnpm build` passes.
- The full Vitest run completed with 4,754 passing and 28 failing tests.
All 23 source-test failures reproduce unchanged on parent head
`58cfe61a33191ce03d965d65085d26064b4888ba`; the other 5 are duplicate
executions from stale `server/dist` output. The failures are unrelated
macOS path/listener and scheduler-fixture failures, so there is no new
bad commit for bisect to localize.
- All required CI checks pass for the current head, including build,
typecheck/release registry, all server and workspace shards, serialized
server suites, canary, and e2e.
- A fresh Greptile review for `506b7fa2d83c36bfa5fd722ee9d95b0c7431c241`
reports 5/5, “safe to merge,” with no blocking failure remaining.
## Risks
- A probe or redaction change could hide useful server diagnostics.
- An allowlist change could reject a valid Claude login URL.
- Cleanup recovery changes could affect provider teardown ordering.
- An environment with a live reusable sandbox can no longer be deleted
until the owning issue or execution workspace completes teardown.
- The implementation keeps public Test messages fixed and sends detail
to redacted server logs.
## Model Used
OpenAI GPT-5 via Codex — exact model ID: GPT-5; tool use and code
execution enabled; extended reasoning enabled. The implementation author
