## Stack Context
This is the Nova UI half of Slack account linking. The paired API and database work is [mono#2650](https://github.com/supermemoryai/mono/pull/2650).
## What?
- Preview the Slack and signed-in Supermemory identities before linking.
- Block accounts that are not already organization members.
- Require explicit confirmation when replacing an existing mapping.
- Handle account switching and invalid, expired, used, success, and retry states.
## Why?
Users whose Slack and Supermemory emails differ need a clear, secure way to confirm their identity. The page makes the identities and organization membership requirement explicit before creating or replacing a stable mapping.
Unscoped recall forced sm_project_default even when the caller could only read another organization space, causing a misleading 403 while list and graph operations succeeded. Let the search API choose the caller's readable scope, skip profile enrichment when no concrete scope is selected, and retain upstream error details.
Validated with Biome, Vite production build, and Wrangler deploy dry-run.
Portal the invite-teammate dialog into the settings modal and autofocus the email input, matching the delete-org dialog fix. Stacked body-portaled dialogs broke focus so the email field stopped accepting input after the first invite.
Fixes ENG-1110
workspaceDomainFromEmail returned the raw domain for free providers, so a gmail.com user picking Team was shown gmail.com as their company domain. Confirming it named the org "Gmail", persisted brainWorkspaceDomain, and ran company research against Gmail.
It now returns null for consumer providers, so the confirm step starts empty and requires a real company domain.
- Drop the company-brain-beta PostHog flag gate; Team mode is available to all users.
- Remove the invite-only gate card and the effectiveMode downgrade that silently wrote brainMode: "personal" on team signups.
- Add a "Use a personal workspace instead" link to the domain-confirm step, which had no way back once the gate stopped catching users.
Fixes ENG-1106
## Summary
- Documents that mono attaches Scale 14d trial + Company Brain after Slack OAuth from `/brain`.
Stacks on #1310. Billing implementation is in mono.
New /brain route creates the org straight from signup and redirects into the Slack install, so onboarding has no domain-confirmation step. Returning from OAuth shows an Open Slack handoff instead of a toast.
Also models the terminal research error state: polling stops, the UI retries once, and the docked header no longer gates Continue on research finishing.
## Stack context
Stacks on #1306, which moves Company Brain settings into the revamped Configure page.
Backend contract and runtime support: supermemoryai/mono#2581. The UI safely hides any effort controls omitted by an older backend response.
## What changed
- Adds independent Low, Medium, High, and Extra high reasoning controls for Main, Triage, and Research.
- Saves model and reasoning edits together through the existing partial PATCH.
- Keeps controls visible but disabled for non-admin members.
- Explains that Extra high maps to High for Grok and GPT providers.
## Validation
- `bunx biome check apps/web/hooks/use-brain-models.ts apps/web/components/settings/company-brain-models.tsx`
- `bun run build` in `apps/web`
- `git diff --check`
The standalone web TypeScript command still reports pre-existing unrelated errors outside these files.

Adds an admin-gated Models tab (main/triage/research pickers) that reads/writes the mono /brain/models endpoint, shown only for Company Brain orgs. Extracts a shared useOrgMemberRole hook so the brain settings sections dedupe the getActiveMember call.
