Phase 4 Plan 02: Portal RBAC Integration Summary

Role-based portal with Auth.js JWT carrying role+tenants, operator path restrictions, tenant switcher, impersonation banner, invite acceptance page, and user management pages

Performance

• Duration: ~5 min
• Started: 2026-03-24T23:02:53Z
• Completed: 2026-03-24T23:07:17Z
• Tasks: 3
• Files modified: 9 (4 modified, 5 created from scratch + 3 new pages)

Accomplishments

• JWT now carries role + tenant_ids + active_tenant_id; proxy enforces role-based redirects silently
• Tenant switcher updates active_tenant_id in JWT without page reload, invalidates TanStack Query cache
• Three new pages: invite acceptance (public), per-tenant users, platform admin global users

Task Commits

1. Tasks 1+2: Auth.js JWT + nav + tenant switcher + impersonation banner - fcb1166 (feat)
2. Task 3: Invite acceptance page + user management pages - 744cf79 (feat)

Files Created/Modified

• packages/portal/lib/auth-types.ts - Module augmentation: role, tenant_ids, active_tenant_id in JWT/Session/User types
• packages/portal/lib/auth.ts - JWT callbacks carry role+tenants, trigger=update for tenant switch and impersonation clear
• packages/portal/proxy.ts - /invite public, customer_operator restricted from billing/users/admin, role-based landing page
• packages/portal/components/nav.tsx - Role-filtered nav with Users and Platform admin items
• packages/portal/components/tenant-switcher.tsx - Multi-tenant dropdown, Auth.js update() + queryClient invalidation
• packages/portal/components/impersonation-banner.tsx - Fixed amber banner with exit button
• packages/portal/app/(dashboard)/layout.tsx - Integrates ImpersonationBanner and TenantSwitcher
• packages/portal/app/invite/[token]/page.tsx - Password form, POST /api/portal/invitations/accept, redirect to /login
• packages/portal/app/(dashboard)/users/page.tsx - Tenant user list, invite dialog, resend pending invitations
• packages/portal/app/(dashboard)/admin/users/page.tsx - Cross-tenant user table, tenant+role filters, invite with tenant selector

Decisions Made

• base-ui DialogTrigger uses render prop not asChild — the shadcn components are base-ui based, not Radix
• base-ui Select onValueChange typed as (string | null) — filter state setters use ?? "" to coerce null
• zod v4 z.enum() does not accept required_error option — removed from both user pages
• Next.js 15 params is a Promise in page components — unwrap with use(params) per decision from Phase 3

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed base-ui component API incompatibilities

• Found during: Task 3 (TypeScript compilation)
• Issue: Code written using Radix/shadcn API conventions (asChild, onValueChange: (string) => void, required_error in zod enum). The portal uses base-ui primitives which have different APIs.
• Fix: Replaced DialogTrigger asChild with DialogTrigger render={<Button>}. Wrapped Select with Controller from react-hook-form. Changed filter onValueChange handlers to use ?? "". Removed required_error from z.enum() calls.
• Files modified: app/(dashboard)/users/page.tsx, app/(dashboard)/admin/users/page.tsx
• Verification: npx tsc --noEmit passes with zero errors
• Committed in: 744cf79 (Task 3 commit)

---

Total deviations: 1 auto-fixed (Rule 1 - Bug) Impact on plan: Auto-fix necessary for TypeScript compilation. No scope creep — same functionality, correct component APIs.

Issues Encountered

• Tasks 1 and 2 files (auth.ts, auth-types.ts, proxy.ts, nav.tsx, tenant-switcher.tsx, impersonation-banner.tsx, layout.tsx) were already fully implemented from Plan 01 execution. Verified TypeScript clean and committed the staged changes.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Portal RBAC is fully wired: JWT contains role+tenants, proxy enforces access, nav filters by role
• User management pages exist and are wired to expected API endpoints
• Plan 03 needs to implement the backend API endpoints: GET /api/portal/tenants/{id}/users, GET /api/portal/admin/users, POST /api/portal/invitations/{id}/resend
• Invite acceptance page wired to POST /api/portal/invitations/accept (implemented in Plan 01)

Self-Check: PASSED

• All 9 portal files confirmed present on disk
• Commit fcb1166 (Tasks 1+2) confirmed in git log
• Commit 744cf79 (Task 3) confirmed in git log
• TypeScript compiles clean (zero errors)
