fix(oauth): allow CIMD clients to mint authorization codes

[kentcdodds]

Host networking got CIMD fetch working. Clicking Authorize then 500’d:

FOREIGN KEY constraint failed in createAuthorizationCode → authorization_codes.client_id references oauth_clients(id).

Kody’s client_id is https://kody.codes/oauth/client-metadata.json. That is not a row in oauth_clients (by design; refresh tokens already omitted this FK).

This migration drops the FK so CIMD authorize can mint a code. The rebuild runs in one transaction (Bugbot). Deleting a static client still deletes its codes.

Test Plan

• npm run validate (254 tests)
• CIMD authorize POST returns 302 with a code and does not insert oauth_clients
• Authorization-code-only CIMD clients can exchange a code without a stub client row
• Version 8 copies existing authorization codes and recreates indexes
• After deploy, /health commit.sha is no longer dc9bc4b…
• Retry Kody authorize and click Authorize — should redirect to Kody, not 500

Checklist

• Tests updated
• Docs updated

📝 Walkthrough

Walkthrough

The changes update migration 8 to support URL-based authorization-code clients, preserve existing data, limit migration targets, test metadata-client authorization, and remove authorization codes when an OAuth client is deleted.

Changes

OAuth client lifecycle

Layer / File(s)	Summary
Authorization-code schema migration app/db/migrations.ts, app/db/migrations.analytics.test.ts	Migration 8 rebuilds authorization_codes in a transaction without the oauth_clients foreign key. It preserves existing rows and recreates indexes. Tests cover the schema and upgrade path.
Bounded migration setup app/db/migrations.ts, app/db/test-database.ts	migrate accepts an optional target version. createMigratedTestDatabase passes that target through.
URL metadata client authorization app/oauth/client-metadata.test.ts	Integration coverage verifies metadata resolution, PKCE handling, redirects, authorization-code issuance, state preservation, and the absence of a static client row.
Client deletion cleanup app/oauth/clients.ts	deleteClient removes authorization codes for the client instead of removing its refresh tokens.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to e6031

The PR removes the foreign-key restriction needed for CIMD clients to mint authorization codes and adds validation for the migration and exchange flows; no actionable merge-blocking risk remains beyond normal checks and review.
