## 📜 Phase 0: Pre-Remediation (Setup)
**Date**: December 19, 2025

### Achievements
- Established test suite baseline (100% pass rate).
- Generated initial PHPStan baseline (1,199 errors).
- Identified "Safe Domains" (Auth, Tenancy, Metrics, Clients).
- Created this tracking infrastructure.

**Lecciones Aprendidas**:
- La importancia de tener `test-cleanup` script para validar estado antes de refactorizar.
- Identificar dominios "verdes" (sin errores) al inicio evita trabajo innecesario.

## 🧹 Phase 1: Quick Wins (Trivial Fixes)
**Status**: ✅ Complete | **Changes**: ~300 errors resolved

### Scope & Execution
Focus: Changes with low risk and high volume (type annotations, removing dead code).

1.  **Deprecated Parameters**: Fixed param reordering in `FormBuilder` and `FormAutofill`.
2.  **Unnecessary Checks**: Removed redundant `isset()` and null coalescing in 7 files.
3.  **Dead Catch Blocks**: Removed 14 unneeded try/catch blocks masking real errors.
4.  **Always True/False**: Fixed 10 controllers where `editMode` logic was broken (Logical Bug Found!).
5.  **Unreachable Code**: Removed debug `dd()` calls left in production code.

**Key Commits**:
- `0a7323e8e` docs(phpstan): Phase 1 - Quick Wins COMPLETE

## 🛡 Phase 2: Core Type Safety
**Status**: ✅ Complete | **Changes**: ~229 errors resolved

### Scope & Execution
Focus: Strengthening the typing system and fixing actual bugs masked by PHP's loose typing.

#### Session 1: Namespace & Imports (~30% of failures)
- **Fix**: Corrected namespaces `Netsuite` -> `NetSuite` and casing issues in `Ipaas`.
- **Fix**: Added missing `use Throwable;` and `use QueryException;` to 106 catch blocks.
- **Lesson**: Don't use regex for imports; verify file content first.

#### Session 2: Type Mismatches
- **Fix**: `Update Actions` - Removed `is_string(array_merge(...))` checks which were always false.
- **Fix**: `SubflowStateDiagnostics` - Added explicit `(int)` casting for redis stats.

#### Session 3: Parameters & Variables
- **Fix**: Refactored 29 `DeleteAction` files into a Generic Delete Action to fix undefined `$input` variables.
- **Fix**: `strcmp` parameter types in Controllers.

**Key Commits**:
- `f0ba33b91` fix(phpstan): Resolve undefined variable errors
- `2e11e61bc` refactor: Complete PHPStan Phase 2

## � Phase 3: Application Layer
**Status**: ✅ Complete | **Changes**: ~149 errors resolved

### Scope & Execution
Focus: Controllers, Jobs, and Services.

1.  **Controllers**: fixed 60+ errors. Standardized request validation types and response return types.
2.  **Services**: fixed 21 errors. Dependency Injection types resolved.
3.  **Jobs**: fixed 68 errors. `DuplicatePreventionTrait` typing and `handle()` return types.

**Key Commits**:
- `fc5f60748` chore: complete Phase 3

---

## � Phase 4: Domain Layer (The Big One)
**Status**: ✅ Complete | **Changes**: ~482 errors resolved

### Scope & Execution
Focus: The core business logic domains (`src/Domain/*`).

#### 4.1 iPaaS & Integrations
- Resolved logic errors in generic `ApiNode`, `MapNode`, and `ConnectorService`.
- Fixed type signatures for Flow execution engine.
- Commit: `9c09beec2` refactor(ipaas): resolve 51 PHPStan Level 5 errors

#### 4.2 RecordTypes
- Fixed meta-programming models (RecordType, Field).
- Commit: `87a25317f` refactor(record-types): resolve 4 PHPStan Level 5 errors

#### 4.3 Other Domains (WorkOrders, Projects, Customers)
- **Achievement**: This was expected to be Phase 5, but was completed early.
- **Fixes**: Standardized Action classes (`CreateProject`, `UpdateWorkOrder`) to use consistent `normalizeBoolean` and `convertTimeToDecimal` helpers.
- **Fixes**: Resolved Model property accessors for magic fields.
- Commit: `927b3920c` refactor: PHPStan Phase 4.3 - Fix type errors
