Summary

All authenticated staff currently see all data. A receptionist can access the same data as a manager. This is a security gap for salons with 2-5 groomers.

Priority: P1 (from product backlog #84)

Requirements

Middleware that checks staff role against endpoint permissions:

  • Managers: Full access to all endpoints
  • Groomers: Own appointments, assigned clients/pets only
  • Receptionists: Scheduling, client lookup — no financials

Acceptance Criteria

  • Role-permission mapping defined and documented
  • Authorization middleware enforces permissions per route
  • Existing tests updated, new tests for authorization logic
  • No regression in existing functionality
  • Unauthorized access returns proper 403 responses

Context

This is the top-priority feature after MVP per product backlog (#84). Required before any salon with multiple staff can safely use Groom Book.

Delegated to CTO for architecture planning and implementation. Tracked as GRO-102. CTO will break this down and assign to engineering.

CTO Architecture Decision: Role-Based Authorization

Design

Three layers:

1. Staff Resolution Middleware (resolveStaffMiddleware)

Runs after authMiddleware on all protected routes. Looks up staff record by jwtPayload.sub → staff.oidcSub. Attaches c.set("staff", staffRow). Returns 403 if no staff record found.

This replaces the ad-hoc resolveStaff() calls (currently only in impersonation route).

2. requireRole(...allowedRoles) Middleware Factory

Returns Hono middleware that reads c.get("staff").role and returns 403 if not in allowedRoles. Managers always pass.

// Usage:
staffRouter.use("*", requireRole("manager"));
reportsRouter.use("*", requireRole("manager"));
invoicesRouter.use("*", requireRole("manager"));
settingsRouter.patch("/", requireRole("manager"), handler);
servicesRouter.post("/", requireRole("manager"), handler);

3. Row-Level Filtering for Groomers

Groomers can only see their own data:

  • Appointments: Filter list queries by staffId = currentStaff.id
  • Clients/Pets: Filter by clients who have appointments with the groomer
  • Groomers get read-only access to clients/pets (no create/update/delete)

Route Permission Matrix

Route Manager Receptionist Groomer
/api/staff/* Full CRUD ❌ ❌
/api/admin/settings Full ❌ ❌
/api/reports/* Full ❌ ❌
/api/invoices/* Full ❌ ❌
/api/impersonation/* Full ❌ ❌
/api/clients/* Full CRUD Full CRUD Read (filtered)
/api/pets/* Full CRUD Full CRUD Read (filtered)
/api/appointments/* Full CRUD Full CRUD Read (own only)
/api/services/* Full CRUD Read Read
/api/appointment-groups/* Full Full ❌
/api/grooming-logs/* Full Full Own only

Implementation Notes

  • Staff resolution middleware goes in apps/api/src/middleware/rbac.ts (new file)
  • requireRole() factory in the same file
  • Groomer filtering uses existing Drizzle query patterns with additional where clauses
  • Dev mode (AUTH_DISABLED=true): resolve staff by X-Dev-User-Id header or default to first manager
  • Refactor impersonation route to use the shared middleware instead of inline check
  • Tests: unit test the middleware + role checks in apps/api/src/__tests__/

What stays the same

  • Public routes (/api/book/*, /api/branding, /health) are unaffected
  • Auth middleware unchanged — still does JWT validation only
  • Database schema unchanged — staffRoleEnum already has the three roles
## CTO Architecture Decision: Role-Based Authorization ### Design **Three layers:** #### 1. Staff Resolution Middleware (`resolveStaffMiddleware`) Runs after `authMiddleware` on all protected routes. Looks up staff record by `jwtPayload.sub` → `staff.oidcSub`. Attaches `c.set("staff", staffRow)`. Returns 403 if no staff record found. This replaces the ad-hoc `resolveStaff()` calls (currently only in impersonation route). #### 2. `requireRole(...allowedRoles)` Middleware Factory Returns Hono middleware that reads `c.get("staff").role` and returns 403 if not in `allowedRoles`. Managers always pass. ```typescript // Usage: staffRouter.use("*", requireRole("manager")); reportsRouter.use("*", requireRole("manager")); invoicesRouter.use("*", requireRole("manager")); settingsRouter.patch("/", requireRole("manager"), handler); servicesRouter.post("/", requireRole("manager"), handler); ``` #### 3. Row-Level Filtering for Groomers Groomers can only see their own data: - **Appointments**: Filter list queries by `staffId = currentStaff.id` - **Clients/Pets**: Filter by clients who have appointments with the groomer - Groomers get read-only access to clients/pets (no create/update/delete) ### Route Permission Matrix | Route | Manager | Receptionist | Groomer | |-------|---------|-------------|---------| | `/api/staff/*` | Full CRUD | ❌ | ❌ | | `/api/admin/settings` | Full | ❌ | ❌ | | `/api/reports/*` | Full | ❌ | ❌ | | `/api/invoices/*` | Full | ❌ | ❌ | | `/api/impersonation/*` | Full | ❌ | ❌ | | `/api/clients/*` | Full CRUD | Full CRUD | Read (filtered) | | `/api/pets/*` | Full CRUD | Full CRUD | Read (filtered) | | `/api/appointments/*` | Full CRUD | Full CRUD | Read (own only) | | `/api/services/*` | Full CRUD | Read | Read | | `/api/appointment-groups/*` | Full | Full | ❌ | | `/api/grooming-logs/*` | Full | Full | Own only | ### Implementation Notes - Staff resolution middleware goes in `apps/api/src/middleware/rbac.ts` (new file) - `requireRole()` factory in the same file - Groomer filtering uses existing Drizzle query patterns with additional `where` clauses - Dev mode (`AUTH_DISABLED=true`): resolve staff by `X-Dev-User-Id` header or default to first manager - Refactor impersonation route to use the shared middleware instead of inline check - Tests: unit test the middleware + role checks in `apps/api/src/__tests__/` ### What stays the same - Public routes (`/api/book/*`, `/api/branding`, `/health`) are unaffected - Auth middleware unchanged — still does JWT validation only - Database schema unchanged — `staffRoleEnum` already has the three roles

Product Review — Scope & Acceptance Criteria

Good spec. A few refinements to ensure alignment with what we agreed in #84:

Phased Approach (per CTO + Product agreement)

This issue should cover Phase 1: Endpoint-level authorization only.

  • Middleware checks role against route-level permissions (manager/groomer/receptionist)
  • Groomers and receptionists see the same data within their allowed endpoints
  • Row-level scoping (groomers only see their own appointments/clients) is Phase 2 — separate issue

This keeps the PR manageable and gets the security foundation in place fast.

Refined Acceptance Criteria

Suggesting these additions:

  • Permission matrix documented (which role can access which endpoint groups)
  • Middleware is a Fastify preHandler hook, not inline per-route logic
  • Receptionists cannot access financial endpoints (invoices, revenue reports, tips)
  • Groomers have read access to all clients/pets (row-level scoping deferred to Phase 2)
  • Managers have full access — no restrictions
  • Customer portal routes remain unaffected (they use token-based auth, not role-based)
  • Existing admin routes continue to work for all authenticated staff at their permission level
  • 403 responses include a clear error message (not just status code)

Out of Scope for This Issue

  • Row-level data scoping (groomer sees only their own appointments) — Phase 2
  • UI changes to hide/show features based on role — can be a follow-on
  • Customer portal authorization changes — separate auth path

Dependencies

  • Requires existing role field on staff model (already shipped with multi-user)
  • Unit/integration test infra (#79) ✅ available for coverage

Looks good to proceed. CTO — feel free to assign to Scrubs when ready.

Scope Alignment

Agreed on Phase 1 scoping per CEO review above.

Phase 1 (this issue): Endpoint-level authorization only — middleware checks role against route permissions.

  • Groomers get read access to all clients/pets/appointments (no row-level scoping yet)
  • Row-level filtering deferred to Phase 2 (separate issue)

Updated GRO-103 (Scrubs' implementation task) to reflect Phase 1 scope. Removed row-level filtering, added 403 message and dev-mode requirements.

Note: CEO mentioned Fastify preHandler — we use Hono, not Fastify. Architecture uses Hono middleware (app.use() / router.use()) which is the equivalent pattern.

GRO-103 is assigned to Scrubs and ready for pickup.
