## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The UI keeps a selected company in `CompanyProvider` with two
writers: a bootstrap effect that repairs invalid selections, and a
Layout route-sync effect that selects the company the URL prefix names
> - The route-sync matches the URL against the full company list
(archived included), while the bootstrap resolver only accepted
companies from the sidebar-filtered non-archived list
> - On any archived company's URL the two effects overwrite each other's
selection in a synchronous loop until React throws error #185 ("Maximum
update depth exceeded") and unmounts the root to a blank page — armed by
remembered last-visited paths, back/forward navigation, or bookmarks, on
first load and client navigation alike
> - This pull request makes an already-selected company only need to
exist, keeping the sidebar filter for fresh-boot resolution where no
explicit selection exists
> - The benefit is that archived company URLs render instead of blanking
the entire app
## Linked Issues or Issue Description
No existing issue. Description follows the bug template:
**What happened?**
Opening (or back-navigating to) a URL whose company prefix belongs to an
archived company blanked the whole app with `Minified React error #185`.
Console in dev mode: "Maximum update depth exceeded. This can happen
when a component calls setState inside useEffect…". A workspace whose
first/seeded company was archived hit this on every load of its
remembered URL.
**Expected behavior**
An archived company's URL renders its pages (the company still exists
and its API routes serve data). The sidebar simply does not feature
archived companies, and fresh boots still land on a non-archived
company.
**Steps to reproduce**
1. Create two companies; archive one (`PATCH /api/companies/:id` with
`status: "archived"`).
2. Navigate to `/{archivedPrefix}/dashboard` — direct load or
client-side back-navigation.
3. Before this fix: React #185 and an unmounted blank page (reproduced
deterministically by the new e2e test).
## What Changed
- `ui/src/context/CompanyContext.tsx`:
`resolveBootstrapCompanySelection` keeps an explicitly selected company
that exists in the full company list; stored-id and default resolution
still prefer sidebar (non-archived) companies.
- `ui/src/context/CompanyContext.test.tsx`: resolver keeps an
archived-but-existing selection; a truly deleted selection is still
replaced.
- `tests/e2e/archived-company-url.spec.ts`: end-to-end regression
driving both field shapes (direct load and back-navigation onto an
archived company URL); it failed with the exact #185 console errors
before the fix and passes after.
## Verification
- `pnpm vitest run src/context …` in `ui/` — 122 tests pass (includes
the new resolver cases).
- `npx playwright test --config tests/e2e/playwright.config.ts
archived-company-url` — fails before the fix (captured "Maximum update
depth exceeded" console errors), passes after.
- `pnpm typecheck` in `ui/` — clean.
## Risks
Low risk. The only behavioral change is that a selection naming an
archived-but-existing company survives the bootstrap repair — previously
that state was unreachable without crashing. Boots with no valid
selection behave exactly as before (non-archived preferred), covered by
the existing and new resolver tests.
## Model Used
- Claude (Anthropic), Claude Fable 5 (`claude-fable-5`), via Claude Code
CLI with extended thinking and tool use (code search, edit, test
execution, Playwright-driven crash reproduction).
