## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Sandbox agents need a safe login path for each supported adapter
> - Codex device login and Claude setup-token login used separate
session stores and route logic
> - Separate stores made session lookup, expiry, and login capability
checks harder to keep consistent
> - This pull request unifies both flows on one session table and one
capability contract
> - The benefit is one company-scoped login model with public session
identifiers and shared lifecycle rules
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting (multiple of the above)
**Problem or motivation**
Codex and Claude sandbox login used separate session stores and
different route paths. This split increased the risk of inconsistent
company scoping, session lookup, and cleanup.
**Proposed solution**
Use `adapter_auth_sessions` for both login flows. Use public session
identifiers for API access. Select login behavior from projected adapter
capability data. Share the route spine, lease arguments, runner
lifecycle, and reaper rules.
**Alternatives considered**
Keep two session tables and add matching fixes to both routes. This
keeps duplicate logic and does not provide one capability contract, so
this pull request uses shared infrastructure.
**Roadmap alignment**
This change supports the shipped Cloud / Sandbox agents milestone in
`ROADMAP.md`.
## What Changed
- Unify Codex device login and Claude setup-token login on
`adapter_auth_sessions`.
- Return and look up sessions with company-scoped public session
identifiers.
- Enforce one active session for each company, owner, and adapter.
- Share the login route spine, sandbox lease arguments, runner
lifecycle, and missing-auth check.
- Add a standalone setup-token reaper with adapter-specific row
selection.
- Add optional login capability projection for adapters and drive route
and UI selection from that data.
- Rename the provider flag to `supportsLoginPty` and validate its
deprecated alias.
- Remove the old Claude setup-token session table and add the required
migrations.
## Verification
- Server typecheck passed with `tsc`.
- Database typecheck passed.
- UI typecheck passed with `tsc -b`.
- Codex login service and route suites passed.
- Setup-token session, route, and reaper suites passed.
- Adapter session schema, plugin validator, capability projection, UI
render, and Daytona suites passed.
- GitHub Actions must confirm the complete CI gate after pull request
creation.
## Risks
- The migrations remove short-lived in-flight login rows during
deployment. A login that spans the migration can continue until its
provider lease expires.
- The Codex credential store remains company-scoped. A cross-owner
credential race remains a documented, board-accepted risk.
- API clients that use internal session row identifiers no longer work.
The API accepts only public session identifiers.
## Model Used
Codex, GPT-5, exact runtime model ID not exposed in this handoff, large
context window, reasoning, and repository tool use. The implementing
engineer produced the code with AI assistance.
