Adds the schema and helper functions needed to support the service-principal auth model for API keys (GH#1190). In this model each API key can have a corresponding auth.users entry (id = rbac_id), so standard auth.uid()-based RLS works identically for human users and API key "users". Changes: - apikeys.service_principal_provisioned column (default false) tracks whether an auth.users entry has been created for the key's rbac_id - get_service_principal_info(apikey_value) returns metadata needed by the edge-function middleware to sign a service-principal JWT - mark_service_principal_provisioned(apikey_id, rbac_id) is called by edge functions (admin client) after creating the auth.users entry - pgTAP tests covering the new column defaults and function behaviour Phase 2 (next PR): update hono_middleware to provision service principals lazily and sign a JWT (sub=rbac_id) for provisioned keys. Phase 3: simplify RLS policies to use auth.uid() directly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…se 2) When an API key request is authenticated, the middleware now lazily provisions an auth.users entry (id = rbac_id) for the key's service principal on first use via supabaseAdmin.auth.admin.createUser(), then marks the key as provisioned via mark_service_principal_provisioned(). A short-lived HS256 JWT (sub = rbac_id, role = authenticated, 1 h) is signed on every API key request and stored in context as `servicePrincipalJwt`. A new `supabaseServicePrincipal()` helper in supabase.ts returns a Supabase client authenticated with this JWT when available, falling back to the legacy capgkey path. The existing capgkey-based auth path is **unchanged** — all current handlers continue to work. Provisioning is non-fatal: any error is logged and the request proceeds normally. Phase 3 will migrate handlers to use `supabaseServicePrincipal()` and simplify RLS accordingly. Supporting changes: - postgres_schema.ts: `service_principal_provisioned` column added to the apikeys Drizzle schema - hono.ts: `servicePrincipalJwt?` added to MiddlewareKeyVariables so the new context key is type-safe - hono_middleware.ts: ServicePrincipalInfoRow type, helper functions fetchServicePrincipalInfo / provisionServicePrincipal / signServicePrincipalJwt / applyServicePrincipal Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add is_service_principal(uuid) helper to identify provisioned SP API keys - Exempt service principals from 2FA and password-policy enforcement in check_min_rights, check_min_rights_legacy, and check_min_rights_legacy_no_password_policy - Add SP JWT fallback path in all three permission functions: when auth.uid() returns an SP's rbac_id (no capgkey header), look up the apikey by rbac_id and evaluate access via key_mode (read/upload/write/all inheriting owner right) - Add 13 pgTAP tests covering is_service_principal, legacy SP fallback with mode mapping, org/app scoping, and no-password-policy variant - Fix plan(14)→plan(13) off-by-one in Phase 1 test file Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

📝 WalkthroughWalkthroughImplements service-principal support for API keys across multiple layers: middleware authentication flow adds provisioning logic with JWT signing; database schema and migrations introduce provisioning state tracking, SQL functions for metadata retrieval and provisioning, and RBAC enhancements with service-principal fallback paths; new utilities enable service-principal client selection; comprehensive test suites validate provisioning and authorization.

Fix typo flagged by pipeline: "mis-marking" → "mismarking".
The pipeline flagged "mis" as a typo. The correct form is "mismarking" (one word, no hyphen).

Thanks for the contribution. We’re closing this PR because we can’t accept repository changes in this form from an integration-style / automated contributor account. For Capgo repos, we expect contributions to be tightly scoped, manually validated, and submitted by an identifiable contributor who can clearly explain the problem, why this approach fits the project, and what was verified locally. Large or bulk-generated change sets without that ownership context create too much review and maintenance risk for us. If this was opened in error or if you are a real contributor behind this account, you’re welcome to resubmit a smaller, clearly-scoped PR with manual validation notes and repository-specific reasoning. |
