Code Cleanup Tasks

Last Updated: 2026-03-05

Notes:

  • 2026-03-05 - Orphaned SQL migration file: app/migrations/FRESH_0032_llm_tutor_hooks.sql defines 5 tables (tutor_sessions, tutor_messages, student_vocabulary, exercise_templates, exercise_attempts) but was NEVER RUN. The Drizzle schema (profile.ts) already pushed a simpler 3-table design (exercise_attempts, vocab_lists, tutor_interactions) to the database. These are two different designs. Action: Delete the SQL migration file since Drizzle schema is authoritative, or keep for future reference if the more elaborate design is needed later.
  • 2026-02-23 - CEFR Level Column for Classes (Future Enhancement): Import data failing because class names in import files (e.g., "Aft Elm", "Pre Int 3") don't match database class names (e.g., "General English A1 - Morning"). Proposed solution: Add cefr_level column to classes table to enable standardized matching across different school naming systems. See CLAUDE.md "Future Enhancements" section for details.
  • 2026-02-12 - Ran FRESH_0015_email_logs.sql migration to add email logs table; no regressions observed.
  • 2026-02-12 - Payments table consolidation question: Two payments tables exist (payments for bookings in business.ts, invoicePayments for invoices in system.ts). Question: should all payments go through invoices? If so, the booking payments table is redundant. Action: Consult business owner to determine if payments should always be invoice-linked. Migration FRESH_0019 renames the DB table to invoice_payments to fix namespace collision in the meantime.

This file tracks pre-existing code quality issues that should be addressed in a future cleanup sprint.

TypeScript Error Summary (Jan 26, 2026 - Updated)

Total Errors: 563 errors across codebase (+1 since last check - stable)

Top 3 Issues (Account for 66% of errors):

  1. 🔴 Snake_case in tests (238 errors) - Test files using tenant_id instead of tenantId
  2. 🟡 Missing schema exports (135 errors) - curriculum.ts and system.ts not exported
  3. 🟡 Type mismatches (74 errors) - Argument type incompatibilities

Quick Fix Opportunity: Phases 1 + 2 below can eliminate 373 errors (66%) in ~3.5 hours

Full Error Log: See typescript-errors-2026-01-26.log for complete error output

Error Distribution by Type:

  • TS2551 (210 errors) - Property does not exist (snake_case vs camelCase naming issues)
  • TS2339 (135 errors) - Property does not exist on type (missing schema exports)
  • TS2345 (74 errors) - Argument type mismatch
  • TS2554 (38 errors) - Expected N arguments but got M
  • TS2769 (28 errors) - No overload matches this call (snake_case in insert statements)
  • TS2305 (23 errors) - Module has no exported member
  • TS2322 (12 errors) - Type is not assignable
  • TS2561 (10 errors) - Object literal excess property checks
  • TS2344 (7 errors) - Type constraint violations (Next.js 15 async params)
  • Other (25 errors) - Various minor type issues

Impact Assessment:

  • 🔴 Critical Impact: Snake_case naming issues (238 errors) - May cause runtime errors in tests
  • 🟡 High Impact: Missing exports (135 errors) - Prevents compilation in strict mode
  • 🟡 Medium Impact: Type mismatches (189 errors) - Type safety issues, unlikely runtime impact
  • 🟢 Low Impact: Next.js 15 async params (7 errors) - Routes work at runtime but type-unsafe

Pre-Existing TypeScript Errors

API Routes - Async Params Pattern (Next.js 16)

Issue: Several API routes use the old synchronous params pattern instead of the new async Promise<> pattern.

Affected Files:

  • src/app/api/admin/audit-log/[id]/route.ts
  • src/app/api/admin/courses/[id]/route.ts
  • src/app/api/admin/enrollments/[id]/route.ts
  • src/app/api/admin/finance/invoices/[id]/route.ts
  • src/app/api/admin/programmes/[id]/route.ts
  • src/app/api/admin/students/[id]/route.ts

Error Example:

Types of property 'GET' are incompatible.
Type '(request: NextRequest, { params }: { params: { id: string; }; })'
is not assignable to
type '(request: NextRequest, context: { params: Promise<{ id: string; }>; })'

Solution: Update all API route handlers to use:

export async function GET(
  request: NextRequest,
  { params }: { params: Promise<{ id: string }> }
) {
  const { id } = await params;
  // ... rest of handler
}

Priority: Medium (affects type safety, but routes work at runtime)

Test Files - Snake Case Column Names (TS2551 + TS2769)

Issue: Test files use snake_case column names (e.g., tenant_id, student_id, class_id) instead of camelCase TypeScript names in both assertions and insert statements.

Affected Files:

  • src/__tests__/rls-policies.test.ts - ~200 errors (assertions checking snake_case fields)
  • scripts/seed-students.ts - Using tenant_id in insert statements
  • Other test/script files with database operations

Error Examples:

// TS2551: Property does not exist
expect(result[0].tenant_id).toBe(tenantId);  // Should be: result[0].tenantId

// TS2769: No overload matches this call
await db.insert(users).values({ tenant_id: '...' })  // Should be: tenantId: '...'

Solution: Update all test files and seed scripts to use camelCase column names from Drizzle schema.

Priority: High (238 errors total - indicates potential runtime errors in tests)

MCP Servers - Snake Case Column Names

Issue: MCP server code uses snake_case column names (e.g., tenant_id, created_at) instead of camelCase TypeScript names.

Affected Files:

  • src/lib/mcp/servers/finance/FinanceMCP.ts
  • src/lib/mcp/servers/identity/server.ts

Error Examples:

Property 'tenant_id' does not exist on type '...'. Did you mean 'tenantId'?
Property 'created_at' does not exist on type '...'. Did you mean 'createdAt'?

Solution: Update all database queries in MCP servers to use camelCase column names from Drizzle schema.

Priority: High (indicates potential runtime errors)

Missing Schema Exports (TS2339)

Issue: Schema files define tables but don't export them from src/db/schema/index.ts, causing import errors across the codebase.

Missing Exports from Curriculum Schema (curriculum.ts):

  • cefrDescriptors - CEFR level descriptors table
  • lessonPlans - Teacher lesson plans table
  • materials - Teaching materials table
  • lessonPlanMaterials - Junction table

Missing Exports from System Schema (system.ts):

  • auditLogs - Immutable audit trail table
  • invoices - Financial invoices table
  • conversations - Communication logs table
  • exports - Data export tracking table

Affected Files:

  • src/__tests__/db-schema.test.ts - Tests for missing tables
  • src/lib/mcp/servers/finance/server.ts - Imports invoices, auditLogs
  • src/lib/mcp/servers/identity/server.ts - Imports auditLogs
  • src/lib/mcp/servers/teacher/server.ts - Imports lessonPlans, assignments, grades
  • src/app/admin/finance/invoices/[id]/page.tsx - Uses invoice-related queries

Solution: Add missing exports to src/db/schema/index.ts:

// Add to index.ts
export * from './curriculum';
export * from './system';

Priority: High (135 errors - prevents compilation in strict mode)

MCP Servers - Missing User Role Field

Issue: Identity MCP server expects a role field on users table that doesn't exist in current schema.

Affected File:

  • src/lib/mcp/servers/identity/server.ts:282-283, 286-287

Solution: Either add role field to users schema or update MCP server to use a different authorization pattern.

Priority: High (indicates incomplete auth implementation)

Pre-Existing ESLint Warnings/Errors

Unused Variables

Files with unused imports/variables:

  • scripts/seed-students.ts:8 - 'enrollments' defined but never used
  • scripts/verify-dessie-data.ts:7 - 'and' defined but never used
  • src/app/admin/bookings/[id]/AddPaymentForm.tsx:49 - 'err' in catch block
  • src/app/admin/bookings/create/CreateBookingForm.tsx:138 - 'err' in catch block
  • src/app/admin/bookings/create/page.tsx:12,19,27,33 - Type imports not used
  • src/app/admin/classes/[id]/page.tsx:7 - 'count' defined but never used

Solution: Remove unused imports or prefix with underscore if intentionally unused (e.g., _err, _enrollments).

Priority: Low (warnings only, no runtime impact)

Explicit any Types

Files with any types:

  • e2e/admin-student-registry.spec.ts:17
  • scripts/apply-rls-policies.ts:34,46
  • scripts/check-rls-policies.ts - multiple locations
  • scripts/seed-students.ts:21
  • scripts/verify-complete.ts - multiple locations
  • src/__tests__/auth-utils.test.ts - multiple locations
  • src/app/admin/_actions/dashboard.ts:71,157

Solution: Replace any with proper TypeScript types or use unknown if type is truly dynamic.

Priority: Medium (reduces type safety)

React Unescaped Entities

File: src/app/admin/courses/page.tsx:56-58

Issue: Multiple unescaped " characters in JSX text.

Solution: Use &quot; or &ldquo;/&rdquo; for proper HTML entity encoding.

Priority: Low (cosmetic, no functional impact)

CommonJS Require Statements

Files:

  • drizzle.config.cjs:1-2
  • scripts/debug-ipv6.js:1
  • scripts/run-fresh-migrations.ts:69

Solution: These are intentional for specific use cases (config files, debug scripts). Can be ignored or marked with ESLint disable comments.

Priority: Low (intentional usage)

Files Created in This Session (Task 1.2)

Clean files with no errors:

  • ✅ app/src/app/admin/students/[id]/page.tsx - Student detail page
  • ✅ app/src/components/admin/students/StudentList.tsx - Updated with "View Details" link

Test/utility scripts:

  • app/scripts/find-dessie.ts
  • app/scripts/verify-dessie-data.ts
  • app/scripts/test-student-detail.ts

Recommended Cleanup Sprint

Current Error Breakdown (562 total):

  • 🔴 Critical (238 errors): Snake_case naming in tests/scripts - Runtime risk
  • 🟡 High (135 errors): Missing schema exports - Compilation blocker
  • 🟡 Medium (74 errors): Type mismatches - Type safety issues
  • 🟢 Low (115 errors): Minor type issues, unused variables, etc.

Cleanup Phases:

  1. Phase 1: Critical Priority (Fixes 238 errors)

    • Effort: 2-3 hours
    • Fix snake_case → camelCase in test files:
      • src/__tests__/rls-policies.test.ts (~200 errors)
      • scripts/seed-students.ts and other seed scripts
    • Update all .values({ tenant_id: ... }) to .values({ tenantId: ... })
    • Update all assertions from result[0].tenant_id to result[0].tenantId

  2. Phase 2: High Priority (Fixes 135 errors)

    • Effort: 30 minutes
    • Add missing schema exports to src/db/schema/index.ts: 
      export * from './curriculum';  // cefrDescriptors, lessonPlans, materials
export * from './system';      // auditLogs, invoices, conversations, exports

  3. Phase 3: Medium Priority (Fixes 81 errors)

    • Effort: 2 hours
    • Update all API routes to async params pattern (Next.js 15)
    • Replace any types with proper TypeScript types
    • Fix MCP server column name issues

  4. Phase 4: Low Priority (Fixes 108 errors)

    • Effort: 1-2 hours
    • Clean up unused variables/imports
    • Fix React unescaped entities
    • Add ESLint disable comments for intentional CommonJS usage

Total Estimated Effort: 6-8 hours to clear all 562 errors Quick Win: Phase 1 + 2 = 3.5 hours to fix 373 errors (66% of total)

Shelved Features (Unlikely to be Required)

Task 1.5: Build Email Alert System

Status: Shelved (unlikely to be required for MVP or beyond)

Original Proposal:

  • Automated email notifications for visa expiry alerts
  • Send emails to admins when student visas are 30/90 days from expiry or expired
  • Scheduled daily cron job to check and send alerts

Why Shelved:

  1. Dashboard suffices: Task 1.4 visa tracking dashboard (/admin/visa) provides real-time visibility
  2. Infrastructure overhead: Requires email service (Resend/Nodemailer/SendGrid), cron scheduler, API keys, templates
  3. Usage uncertainty: Unclear if automated emails are actually needed vs. periodic dashboard checks
  4. Complexity vs. value: 60-90 minutes implementation for potentially low-value feature
  5. Better alternatives: If notifications needed later, consider:
    • Manual "Send Alert" button on dashboard (5 min implementation)
    • Browser notifications / in-app alerts
    • Integrate with unified notification system post-MVP

Technical Requirements (if ever implemented):

  • Email service provider (Resend recommended)
  • Email templates (React Email)
  • Cron scheduler (Vercel Cron or external service)
  • Database: admin notification preferences table
  • Estimated effort: 60-90 minutes

Decision Date: 2026-01-15 Rationale: Focus MVP development on core features. Dashboard provides sufficient visibility. Email infrastructure can be added later if usage patterns prove it's needed.

Note: If visa compliance requires documented notifications, reconsider as Task 1.4.2 post-MVP.

TypeScript Error Cleanup (2026-02-13)

Two Main Categories of Errors Identified:

  1. snake_case vs camelCase in Drizzle ORM (190+ errors)

    • Issue: Test files and some production code use snake_case property names (tenant_id, student_id, class_id) instead of Drizzle's camelCase properties (tenantId, studentId, classId)
    • Root cause: Drizzle ORM schema defines TypeScript properties in camelCase but maps to snake_case PostgreSQL columns automatically. Code must use camelCase when accessing schema properties.
    • Example fix: 
      // WRONG:
await db.insert(users).values({ tenant_id: '...', role: 'admin' })
expect(result[0].tenant_id).toBe(tenantId)

// CORRECT:
await db.insert(users).values({ tenantId: '...', primaryRole: 'admin' })
expect(result[0].tenantId).toBe(tenantId)
    • Affected files: rls-policies.test.ts, test files in __tests__/ folders, seed scripts

  2. Next.js 15 async params pattern in tests (100+ errors)

    • Issue: Test mocks use synchronous params { params: { id: string } } but Next.js 15 routes expect async { params: Promise<{ id: string }> }
    • Root cause: Next.js 15 made route handler params async. Tests need to mock this correctly.
    • Example fix: 
      // WRONG:
const mockParams = { params: { id: 'test-id' } };
await GET_BY_ID(mockRequest, mockParams);

// CORRECT:
const mockParams = { params: Promise.resolve({ id: 'test-id' }) };
await GET_BY_ID(mockRequest, mockParams);
    • Affected files: All API route test files (courses.test.ts, enrollments.test.ts, students.test.ts, etc.)

Progress (2026-02-13):

  • Fixed rls-policies.test.ts snake_case → camelCase (23 errors)
  • Fixed query components unknown type issues (8 errors)
  • Fixed 6 test files with Promise.resolve params pattern (~100 errors)
  • Fixed programmes.ts schema snake_case → camelCase
  • Fixed teachers/route.ts, users/route.ts, users/[id]/route.ts snake_case issues
  • Fixed rooms/route.ts Zod 4.x z.record() argument issue
  • Fixed students/[id]/route.ts - attendance/grades schema alignment
  • Fixed MCP routes error code type assertions
  • Fixed form components err is unknown type issues
  • Fixed MCPHost.ts session variable naming
  • Fixed db/index.ts connectionString possibly undefined
  • Fixed MCPHostRefactored.ts unknown type issues in .some() callbacks
  • Fixed hash-chain.ts snake_case → camelCase for Drizzle compatibility
  • Fixed cumulative-lateness.ts metadata type assertions
  • Fixed mcp/capabilities/route.ts array type assertions
  • Fixed multiple "Cannot find name 'err'" issues (catch block typos)
  • Reduced from 291 → 119 errors (59% reduction, 172 errors fixed)

Remaining Error Categories (2026-02-13):

  • Test files: ~100 errors (Jest mock typing, snake_case in hash-chain tests)
  • MCP servers: ~8 errors (Drizzle query overload issues)
  • Supabase mocks: ~4 errors (middleware.ts, server.ts mock type compatibility)
  • Other: ~7 errors (StudentRegistry types, notifications.ts, attendance routes)
