feat(regions): give every organization a data region - #994
Merged

Conversation
An organization now lives in exactly one regional instance, recorded as `regions` in its Clerk public metadata. Missing means US, so existing organizations need no backfill. The array leaves room for spanning both regions later. - The API refuses a session for an organization from another region with a 403 OrganizationWrongRegionError. A failed Clerk read lets the request through; keys are per instance, so this steers people rather than guarding data. - Organizations are created server-side (POST /api/organizations, an org-less Clerk session) so the region is set from the start. The browser SDK cannot write public metadata. - The dashboard knows its region (VITE_MAPLE_REGION) and where the other regions live (prd only). The org switcher labels each org US or EU and opens other-region orgs in their own dashboard, a wrong-region screen replaces the app for them, org settings shows the data region, and the create dialog picks the region.

…ionWrongRegionError
The organization Clerk creates at sign-up has no region, so onboarding now opens with "Where should your data live?" wherever more than one region exists. Choosing writes `regions` onto the organization through PUT /api/organizations/region. Choosing this dashboard's region continues onboarding here; choosing the other moves it to that region's /quick-start, where the step is already done because it is read from the organization. The server allows this once, for admins, and never after the organization has held a plan, so an organization with data cannot be moved away from it. Repeating the same region succeeds. The region check now caches only a "served here", so an organization that just moved is not refused for a minute by the instance it moved to.

- Around line 147-149: Update the wrongRegion guard in the root route to require
orgRegion.chosen before blocking access for an organization not served here.
This lets organizations without a chosen region reach region onboarding while
preserving the guard for organizations with a chosen region.
In `@packages/backend/src/services/org/OrganizationRegionService.ts`:
- Around line 62-66: Update the cache condition in the organization lookup flow
to cache only when the region was explicitly chosen and is served by this
instance. Use organizationRegionChosen from `@maple/domain/organization-regions`
alongside organizationServedIn, so the default US region is not cached.
In `@packages/backend/src/services/org/OrganizationService.ts`:
- Around line 369-390: Update chooseRegion so organizations without explicit
regions metadata cannot select a new region based only on lacking plan history;
verify the organization is genuinely new using a reliable onboarding check, or
normalize legacy organizations to regions: ["us"] before this path allows region
selection. Preserve the existing same-region retry and responseHasPlanHistory
checks.
In `@packages/domain/src/http/organizations.ts`:
- Line 100: Update the Authorization applied to OrganizationsApiGroup so
chooseRegion remains protected by organization-access and admin checks but
bypasses the current-region check; preserve the handler’s ability to process
initial selection and same-region retries.

…shboard Review follow-ups on the onboarding region step: - An organization Clerk creates on the EU dashboard reads as US, so it hit the wrong-region screen and the region check refused the choice itself. Choosing now has its own group behind RegionlessSessionAuthorization (a session check without the region test), the root gate sends an organization that can still choose to /quick-start, and quick-start shows the region step before it asks billing. - An organization that predates regions could move to EU if it had never held a plan. A region can now only be chosen within a week of the organization's creation (organizationRegionOpen, shared by web and API). - The region check reused a US-default answer for a minute, so an organization that moved to EU kept being served here. Unchosen organizations are now reused for 5s; chosen ones for a minute.
…gion Organizations that predate regions carry no regions key, so onboarding's region step would let one created in the week before deploy, without a plan, move to EU while its data stays on US. Stamping every existing organization with regions: ["us"] before the step ships closes that. Dry run by default; --apply writes.

…kfill on EU marking - chooseRegion answers with the region read back from Clerk after the write, and onboarding routes by that answer, so two admins choosing at once both land where the later write left the organization. Clerk has no conditional write, so this narrows the race rather than closing it. - backfill-org-regions --apply now also requires --confirm-eu-marked: nothing on an organization records which instance created it, so an unmarked EU organization would be stamped US.

…k fails The metadata write has already landed by then, so failing the request would report an error for a choice that took effect.
…region Found by running the EU sign-up path end to end: - The org switcher sent an organization with no region yet to the US dashboard (the default) and labelled it US. One that can still choose now stays on the current dashboard, where onboarding asks, and shows no region until it has one. - The root asked billing before Clerk had loaded the organization's region. On the EU dashboard that request was refused, and the cached refusal outlived the choice, so onboarding read billing as unknown and dropped the user into the app. Billing now waits for the region.
…ganization On an instance that knows no other region (a dev stage named *-eu), the root sent a new organization it does not serve to /quick-start, which skipped the step because only one region exists, asked billing, got the region refusal, and navigated back to /. Quick-start now also asks when the dashboard does not serve the organization, and waits for the organization's region before asking billing on every Clerk deployment.
The EU instance had no organizations yet, so there is nothing to mark before deploying, and the 7-day window is enough for US organizations.

Why
The US and EU instances share one login, so every organization already exists on both. Until now nothing recorded which instance an org belongs to. Opening the other region's app silently created the org's onboarding and ingest-key rows there, and there was no way to tell which region you were on or to move between them.
What changed
The rule. An organization lives in the regions named by
regionsin its Clerk public metadata. For now that is exactly one. Missing or invalid means["us"], so every existing org stays on US with no backfill (the EU instance had no organizations yet). The rule is@maple/domain/organization-regions, shared by web and API.API.
OrganizationRegionService.ensureServedHereruns after session auth in the v1, internal (session-only) and v2 layers. An org from another region gets a 403OrganizationWrongRegionErrorcarryingorgRegionandregion(v2 maps it to its access-denied envelope). Metadata is cached for 60s per isolate.POST /api/organizationscreates the Clerk org with its region already set. The browser SDK cannot write public metadata. The endpoint uses a newUserSessionAuthorizationmiddleware: a Clerk session with no active org required (makeResolveClerkUserin@maple/auth, sharing the session steps withmakeResolveTenant).MAPLE_REGION(already derived by the stack) is now read into the backendEnv.Web.
VITE_MAPLE_REGIONandVITE_MAPLE_REGION_APP_URLS(prd only, fromresolveRegionAppUrls) are baked in at build.US/EUwhen more than one region exists. Picking an org in the other region opens that region's dashboard.<OrganizationSwitcher>on/org-requiredis replaced with ours, since it would create orgs without a region.install-modal.tsx: renamed the "hosted" check to what it is (the chart's default endpoint), which the EU endpoint is not. Behaviour is unchanged.Before deploying
app.eu.maple.devis a subdomain ofmaple.dev, so sessions should already be shared. Not yet confirmed on prod.Not covered
OrganizationRegionServicehas no unit test of its own because it calls Clerk directly. The rule it applies is tested inorganization-regions.test.ts.Testing
resolveRegionAppUrls, the@maple/authsuite, backend auth and org suites, and two v2 route suites.regions: ["eu"], browser sent to the EU URL). Back on the US app the org got the wrong-region screen, and/api/org-clickhouse-settingsreturned 403OrganizationWrongRegionError. Switching back to a US org loaded the app. The settings row renders.Onboarding region step (added)
The organization Clerk creates at sign-up has no region.
/quick-startnow opens with "Where should your data live?" wherever more than one region exists: two flag cards (US, EU) in the style of the other onboarding steps.PUT /api/organizations/region(organizationRegion.choose), which writesregionsonto the org. This region continues onboarding here; the other region moves the user to that region's/quick-start. "Done" is read from the org's metadata, so the step does not reappear on the other origin.RegionlessSessionAuthorization(the session check without the region test), because an unchosen org reads as US and would otherwise be refused on the EU dashboard, as would a retry after a move. Every other endpoint keeps the region check.organizationRegionOpenholds (no region chosen, org created within 7 days), and never after the org has held a plan (409OrganizationRegionLockedError). Repeating the same region returns 200./quick-startinstead of the wrong-region screen, and quick-start shows the region step before it asks billing.OrganizationRegionServicereuses an unchosen (US-default) answer for 5s and a chosen one for 60s, and never caches a refusal, so an org that just moved is picked up quickly on both instances.regions: ["eu"]and continues to the role step, a retry after a move returns 200, a later change returns 409, the US instance then refuses the org (403), an org that predates regions cannot choose (409), and a single-region stack shows no step and no region labels. The plan-history refusal was not exercised live.Need help on this PR? Tag
