## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Operators use the same board application in self-hosted and
Paperclip Cloud deployments.
> - A Cloud tenant contains one company, so an in-app company switch
does not change the active Cloud stack.
> - Cloud operators need the sidebar and company surfaces to use the
signed-in user's stack portfolio.
> - The server must derive Cloud identity and links from trusted
instance context instead of client input.
> - This pull request adds canonical Cloud context, a trusted stack
portfolio proxy, and Cloud-aware navigation.
> - The benefit is consistent stack switching on Cloud while self-hosted
company behavior stays unchanged.
## Linked Issues or Issue Description
**Subsystem affected**
Cross-cutting: server REST routes and the React board UI.
**Problem or motivation**
A Cloud-managed instance contains one company. The existing company
switcher could only switch records inside that tenant. It could not move
the operator to another Cloud stack. The existing header also gave long
organization names too little width.
**Proposed solution**
Expose a canonical public Cloud context in health data. Add a trusted
server proxy for the current user's stack portfolio. Use that data in
the board UI to switch stacks with top-level navigation. Keep the
existing company behavior on self-hosted instances. Move search into the
navigation and keep long organization names inside the sidebar panel.
**Alternatives considered**
An in-app `/stacks` route was rejected because Cloud tenant hosts
reserve that path and stack selection must wake or authenticate another
tenant. Client-supplied user identity was rejected because the server
can derive the trusted Cloud actor.
**Roadmap alignment**
This change advances the Cloud deployments milestone. It keeps the
product local-first and Cloud-ready without changing the self-hosted
mental model.
## What Changed
- Added canonical Cloud instance context and public health metadata.
- Added a Cloud-only stack portfolio proxy with trusted actor forwarding
and per-user caching.
- Prevented normal company creation on Cloud-managed instances.
- Switched the sidebar and Companies page from company actions to stack
actions on Cloud.
- Added full-page stack navigation and Cloud create-stack links.
- Moved search into the sidebar navigation so the organization name
keeps more width.
- Added truncation and hover recovery for long organization and stack
names.
- Added server and UI regression coverage for Cloud and self-hosted
behavior.
- Updated the implementation specification for the Cloud contracts.
## Verification
- `node scripts/check-token-gates.mjs` passed. All three token gates are
clean.
- `pnpm --dir server exec vitest run src/__tests__/health.test.ts
src/__tests__/cloud-instance.test.ts src/__tests__/cloud-routes.test.ts
src/__tests__/company-cloud-floor.test.ts
src/__tests__/company-portability-routes.test.ts` passed: 5 files and 66
tests.
- `pnpm --dir ui exec vitest run
src/components/SidebarCompanyMenu.test.tsx` passed: 1 file and 11 tests.
- Pre-PR QA report `7da87ca7` passed all 8 acceptance criteria with real
HTTP route factories and real Chromium screenshots in Cloud and
self-hosted modes.
- Security reviews passed for the canonical Cloud context and stack
portfolio proxy.
## Risks
- Cloud stack switching depends on the configured Cloud application and
tenant portfolio URLs.
- The new health `cloud` block is public by design, but it contains only
canonical public instance metadata.
- The stack proxy fails closed on self-hosted instances and derives the
user identity from the trusted actor.
- Self-hosted navigation and company creation retain their existing
paths and behavior.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex, model `gpt-5`. The run used reasoning, repository tools,
shell execution, and GitHub integration. The deployment did not expose
its context-window size.
