🚨 CRITICAL: Fix TypeScript Compilation Errors (115+ errors)

[mehdibalouchi]

🚨 Critical Issue - System Broken

Status: BLOCKING ALL DEVELOPMENT
Priority: P0 - Critical
Impact: Complete development halt

Problem Description

The codebase has 115+ TypeScript compilation errors in source code and 777+ errors in test suite, making development impossible.

Error Categories

1. Import Resolution Issues

   • References to non-existent src/core/ modules (should be src/infra/)
   • Missing export functions like createStorageError
   • Broken module dependencies

2. Type System Issues

   • Object is of type 'unknown' errors throughout storage tests
   • Missing type annotations on database functions
   • Effect-TS composition type mismatches

3. Infrastructure Migration Incomplete

   • Agent layer still references old src/core/ast.ts path
   • Inconsistent module structure between agent and infra layers
   • Broken abstraction boundaries

Impact Assessment

• ❌ deno check src/: 115 compilation errors
• ❌ deno test --allow-all: 777 type errors
• ❌ Development workflow: Completely blocked
• ❌ CI/CD: Tests cannot run
• ❌ New features: Cannot be developed

Root Cause Analysis

Based on prd.md, this appears to be incomplete migration from the infrastructure refactoring phase. The infrastructure layer (src/infra/) is complete, but the agent layer still references old patterns and paths.

Required Actions

Phase 1: Import Resolution (URGENT)

• Fix all src/core/ → src/infra/ import paths
• Restore missing exports in src/infra/errors.ts
• Update agent layer imports to use infrastructure modules

Phase 2: Type System Recovery

• Fix database function type annotations
• Resolve Effect-TS composition type errors
• Add proper type guards for unknown objects

Phase 3: Test Suite Recovery

• Fix 777 test compilation errors
• Update test imports and type assertions
• Validate test coverage after fixes

Acceptance Criteria

✅ Success Metrics:

• deno check src/ passes with 0 errors
• deno test --allow-all runs successfully
• All imports resolve correctly
• Type system is fully functional
• Development workflow restored

Estimated Timeline

2-3 hours of focused refactoring work following the patterns established in the infrastructure layer.

This issue MUST be resolved before any feature development can continue.
