Subject: [PATCH 01/21] Enhance financial reporting with contract type
 integration

- Updated `FinAppRepository` to include `contractType` in data retrieval for employees and projects.
- Introduced `getContractTypeByDate` utility function to fetch contract types based on date.
- Modified `WeeklyFinancialReportRepository` and formatter to incorporate contract type in report generation.
- Updated tests to reflect changes in data structure and report formatting.

These enhancements improve the accuracy and detail of financial reports, providing clearer insights into contract types alongside revenue metrics.

Subject: [PATCH 03/21] Add unit tests for getContractTypeByDate function

- Introduced comprehensive tests for the getContractTypeByDate utility function.
- Covered various scenarios including handling of undefined and empty inputs, invalid dates, and correct contract type retrieval based on date.
- Ensured robustness by testing edge cases and filtering out invalid entries in contractTypeHistory.

These tests enhance the reliability of the contract type determination logic and improve overall code quality.

Subject: [PATCH 05/21] Add weekly financial report workflow and enhance
 marginality calculations

- Introduced a new `launchWeeklyReport.ts` file to initiate the weekly financial reports workflow using Temporal.
- Updated `types.ts` to include `effectiveMarginalityIndicator` in the `TargetUnit` interface.
- Added effective marginality thresholds in `weeklyFinancialReport.ts` for better categorization.
- Enhanced `MarginalityCalculator` with a new `EffectiveMarginalityCalculator` class to compute effective marginality levels and indicators.
- Modified `WeeklyFinancialReportFormatter` to incorporate effective marginality indicators in report formatting.
- Updated `WeeklyFinancialReportRepository` to aggregate effective marginality data and indicators.

These changes improve the financial reporting process by integrating effective marginality calculations and enhancing the overall report structure.

Subject: [PATCH 08/21] Refactor MarginalityResult and
 EffectiveMarginalityResult interfaces to use effectiveMarginalityIndicator

- Updated the `MarginalityResult` and `EffectiveMarginalityResult` interfaces to replace the `indicator` property with `effectiveMarginalityIndicator` for clarity.
- Modified the `MarginalityCalculator` and `EffectiveMarginalityCalculator` classes to return the updated property in their results.

These changes enhance the consistency and clarity of marginality calculations in the financial reporting process.

+# System Overview
+
+## What is the Weekly Financial Summary System?
+
+The Weekly Financial Summary system is an automated workflow that generates comprehensive financial reports for Target Units (TUs) - specific project groups within your organization. The system processes data from multiple sources to provide actionable insights about project profitability and performance.
+
+## 🎯 System Purpose
+
+### For Project Managers
+
+The system helps you:
+
+- **Monitor project profitability** in real-time
+- **Identify performance trends** across different Target Units
+- **Make data-driven decisions** about resource allocation
+- **Track financial health** of ongoing projects
+
+### For Financial Analysts
+
+The system provides:
+
+- **Automated financial calculations** with consistent methodology
+- **Integration with multiple data sources** (Redmine, QuickBooks, MongoDB)
+- **Standardized reporting format** for easy analysis
+- **Historical data tracking** for trend analysis
+
+## 🔄 How the System Works
+
+The Weekly Financial Summary workflow follows a structured process:
+
+```mermaid
+graph TD
+    A[Start Workflow] --> B[Get Target Units from Redmine]
+    B --> C[Fetch Financial Data from MongoDB & QBO]
+    C --> D[Calculate Financial Metrics]
+    D --> E[Generate Formatted Report]
+    E --> F[Send Report to Slack]
+    F --> G[End Workflow]
+
+    style A fill:#e1f5fe
+    style G fill:#e8f5e8
+    style B fill:#fff3e0
+    style C fill:#fff3e0
+    style D fill:#f3e5f5
+    style E fill:#f3e5f5
+    style F fill:#e8f5e8
+```
+
+### Step-by-Step Process
+
+1. **Data Extraction**: The system retrieves Target Unit data from Redmine, including:
+
+   - Project information and assignments
+   - Time tracking data (hours worked)
+   - User assignments and project relationships
+
+2. **Financial Data Integration**: The system fetches additional data from:
+
+   - **MongoDB**: Employee rates, project rates, and historical data
+   - **QuickBooks Online**: Actual revenue data for effective calculations
+
+3. **Calculation Engine**: The system performs complex financial calculations:
+
+   - Revenue calculations based on project rates
+   - Cost calculations based on employee rates
+   - Margin and marginality calculations
+   - Effective revenue and margin calculations
+
+4. **Report Generation**: The system creates formatted reports with:
+
+   - Color-coded performance indicators
+   - Detailed financial breakdowns
+   - Summary statistics and trends
+
+5. **Delivery**: Reports are automatically sent to Slack channels for easy access and collaboration.
+
+## 📊 Key Components
+
+### Target Units (TUs)
+
+Target Units are specific project groups that represent:
+
+- **Client projects** with defined scopes and deliverables
+- **Internal initiatives** with measurable outcomes
+- **Resource allocations** with time and cost tracking
+
+### Financial Metrics
+
+The system calculates several key financial indicators:
+
+| Metric                    | Description                                   | Business Impact                 |
+| ------------------------- | --------------------------------------------- | ------------------------------- |
+| **Revenue**               | Project rate × hours worked                   | Shows project income potential  |
+| **COGS**                  | Employee rate × hours worked                  | Represents actual project costs |
+| **Margin**                | Revenue - COGS                                | Direct project profitability    |
+| **Marginality**           | (Margin ÷ Revenue) × 100%                     | Profitability percentage        |
+| **Effective Revenue**     | Actual QBO revenue                            | Real-world income               |
+| **Effective Margin**      | Effective Revenue - COGS                      | Actual profitability            |
+| **Effective Marginality** | (Effective Margin ÷ Effective Revenue) × 100% | Real profitability percentage   |
+
+### Performance Categories
+
+Target Units are categorized by their marginality performance:
+
+- 🟢 **High Performance** (55%+ marginality): Excellent profitability, maintain current approach
+- 🟡 **Medium Performance** (45-55% marginality): Good profitability, consider optimization opportunities
+- 🔴 **Low Performance** (<45% marginality): Needs immediate attention and improvement strategies
+
+## 🎨 Report Structure

+# Financial Metrics and Formulas
+
+This section provides detailed explanations of all financial calculations performed by the Weekly Financial Summary system. These metrics are essential for understanding project profitability and making informed business decisions.
+
+## 📊 Core Financial Concepts
+
+### Revenue vs. Effective Revenue
+
+**Revenue** is calculated based on project rates and represents the expected income from a project.
+
+**Effective Revenue** comes from QuickBooks Online and represents the actual revenue received or invoiced.
+
+This distinction is crucial because:
+
+- **Revenue** shows planned/expected income
+- **Effective Revenue** shows actual business performance
+- The difference can indicate billing issues, scope changes, or pricing adjustments
+
+### COGS (Cost of Goods Sold)
+
+COGS represents the direct costs associated with delivering a project, primarily employee costs based on their rates and hours worked.
+
+## 🧮 Detailed Calculations
+
+### 1. Revenue Calculation
+
+**Formula:**
+
+```
+Revenue = Project Rate × Total Hours
+```
+
+**Example:**
+
+- Project Rate: $80/hour
+- Total Hours: 100 hours
+- Revenue = $80 × 100 = $8,000
+
+**Implementation Details:**
+
+- Project rates are retrieved from MongoDB with historical tracking
+- Rates are determined by the date of work (`spent_on` field)
+- If no project rate is available, the calculation defaults to 0
+
+### 2. COGS (Cost of Goods Sold) Calculation
+
+**Formula:**
+
+```
+COGS = Employee Rate × Total Hours
+```
+
+**Example:**
+
+- Employee Rate: $50/hour
+- Total Hours: 100 hours
+- COGS = $50 × 100 = $5,000
+
+**Implementation Details:**
+
+- Employee rates are retrieved from MongoDB with historical tracking
+- Rates are determined by the date of work (`spent_on` field)
+- If no employee rate is available, the calculation defaults to 0
+
+### 3. Margin Calculation
+
+**Formula:**
+
+```
+Margin = Revenue - COGS
+```
+
+**Example:**
+
+- Revenue: $8,000
+- COGS: $5,000
+- Margin = $8,000 - $5,000 = $3,000
+
+### 4. Marginality Calculation
+
+**Formula:**
+
+```
+Marginality = (Margin ÷ Revenue) × 100%
+```
+
+**Example:**
+
+- Margin: $3,000
+- Revenue: $8,000
+- Marginality = ($3,000 ÷ $8,000) × 100% = 37.5%
+
+**Important Notes:**
+
+- If Revenue is 0, Marginality is set to 0% to avoid division by zero
+- Marginality is expressed as a percentage
+- Higher marginality indicates better profitability
+
+### 5. Effective Revenue Integration
+
+**Source:** QuickBooks Online API
+
+**Process:**
+
+1. System retrieves actual revenue data from QBO
+2. Data is matched to projects using QuickBooks customer references
+3. Revenue is aggregated by project for the reporting period
+
+**Example:**
+
+- QBO shows $10,000 actual revenue for Project A
+- System uses this as Effective Revenue instead of calculated Revenue
+
+### 6. Effective Margin Calculation
+
+**Formula:**
+
+```
+Effective Margin = Effective Revenue - COGS
+```
+
+**Example:**
+
+- Effective Revenue: $10,000
+- COGS: $5,000
+- Effective Margin = $10,000 - $5,000 = $5,000
+
+### 7. Effective Marginality Calculation
+
+**Formula:**
+
+```
+Effective Marginality = (Effective Margin ÷ Effective Revenue) × 100%
+```
+
+**Example:**
+
+- Effective Margin: $5,000
+- Effective Revenue: $10,000
+- Effective Marginality = ($5,000 ÷ $10,000) × 100% = 50%
+
+## 🎯 Performance Classification
+
+### Standard Marginality Thresholds
+
+The system classifies Target Units based on their marginality performance:
+
+```mermaid
+graph LR
+    A[Marginality < 45%] --> B[🔴 Low Performance]
+    C[Marginality 45-55%] --> D[🟡 Medium Performance]
+    E[Marginality ≥ 55%] --> F[🟢 High Performance]
+
+    style B fill:#ffebee
+    style D fill:#fff8e1
+    style F fill:#e8f5e8
+```
+
+### Effective Marginality Thresholds
+
+For effective marginality, the system uses more granular classification:
+
+```mermaid
+graph LR
+    A[Effective Marginality < 30%] --> B[🔴 Very Low]
+    C[Effective Marginality 30-45%] --> D[🟡 Low]

+## 🔍 Real-World Example
+
+Let's walk through a complete calculation using real data:
+
+### Input Data
+
+- **Target Unit**: Altavia TU
+- **Period**: Q3
+- **Total Hours**: 111.8 hours
+- **Employee Rate**: $20.82/hour (calculated from COGS)
+- **Project Rate**: $80.00/hour
+- **Effective Revenue**: $14,073 (from QBO)
+
+### Step-by-Step Calculation
+
+1. **Revenue Calculation**
+
+   ```
+   Revenue = $80.00 × 111.8 = $8,944
+   ```
+
+2. **COGS Calculation**
+
+   ```
+   COGS = $20.82 × 111.8 = $2,327
+   ```
+
+3. **Margin Calculation**
+
+   ```
+   Margin = $8,944 - $2,327 = $6,617
+   ```
+
+4. **Marginality Calculation**
+
+   ```
+   Marginality = ($6,617 ÷ $8,944) × 100% = 74%
+   ```
+
+5. **Effective Margin Calculation**
+
+   ```
+   Effective Margin = $14,073 - $2,327 = $11,746
+   ```
+
+6. **Effective Marginality Calculation**
+   ```
+   Effective Marginality = ($11,746 ÷ $14,073) × 100% = 83%
+   ```
+
+### Performance Classification
+
+- **Standard Marginality**: 74% → 🟢 High Performance (≥55%)
+- **Effective Marginality**: 83% → 🟢 High Performance (≥55%)
+
+## ⚠️ Important Considerations
+
+### Data Quality
+
+- **Rate History**: The system uses historical rate data, so rate changes are tracked over time
+- **Date Matching**: All calculations use the `spent_on` date to ensure accurate rate application
+- **Missing Data**: If rates are unavailable, calculations default to 0 to prevent errors
+
+### Calculation Accuracy
+
+- **Rounding**: All calculations maintain precision until final display
+- **Division by Zero**: Protected against division by zero in marginality calculations
+- **Data Validation**: Input data is validated before calculations begin
+
+### Business Context
+
+- **Effective Revenue**: May differ from calculated revenue due to:
+  - Billing adjustments
+  - Scope changes
+  - Pricing modifications
+  - Payment timing differences
+
+## 🎯 Using These Metrics
+
+### For Project Managers
+
+- **Monitor marginality trends** to identify performance issues early
+- **Compare standard vs. effective metrics** to understand billing accuracy
+- **Use performance categories** to prioritize attention and resources
+
+### For Financial Analysts
+
+- **Validate calculations** against source data
+- **Analyze rate trends** over time
+- **Identify discrepancies** between planned and actual revenue
+- **Audit data quality** and completeness

+#### Q: What is a Target Unit (TU)?
+
+**A:** A Target Unit is a specific project group that represents a client project, internal initiative, or resource allocation with defined scope, deliverables, and measurable outcomes. Each TU tracks time, costs, and revenue for financial analysis.
+
+#### Q: How often are reports generated?
+
+**A:** Reports are generated weekly as part of the automated workflow. The system processes data for the current reporting period and delivers results via Slack.
+
+#### Q: Who receives the reports?
+
+**A:** Reports are sent to designated Slack channels where project managers, financial analysts, and other stakeholders can access them. The specific channels depend on your organization's configuration.
+
+#### Q: Can I access historical reports?
+
+**A:** Yes, historical reports are available in the Slack channel history. You can search for previous reports by date or use Slack's search functionality to find specific Target Units or time periods.
+
+### Financial Metrics Questions
+
+#### Q: What's the difference between Revenue and Effective Revenue?
+
+**A:**
+
+- **Revenue**: Calculated based on project rates and hours worked (planned/expected income)
+- **Effective Revenue**: Actual revenue from QuickBooks Online (real-world income)
+
+The difference can indicate billing improvements, scope changes, or data quality issues.
+
+#### Q: Why might Effective Revenue be different from calculated Revenue?
+
+**A:** Several factors can cause differences:
+
+- **Billing adjustments** or rate changes
+- **Scope modifications** or change orders
+- **Payment timing** differences
+- **Data synchronization** delays between systems
+- **Manual adjustments** in QuickBooks Online
+
+#### Q: What does marginality mean?
+
+**A:** Marginality is the percentage of revenue that remains as profit after covering direct costs (COGS). It's calculated as: (Margin ÷ Revenue) × 100%. Higher marginality indicates better profitability.
+
+#### Q: How are performance categories determined?
+
+**A:** Target Units are categorized by their marginality:
+
+- 🟢 **High Performance**: 55%+ marginality
+- 🟡 **Medium Performance**: 45-55% marginality
+- 🔴 **Low Performance**: <45% marginality
+
+### Data and Integration Questions

Subject: [PATCH 18/21] Add project_hours to test data in WeeklyFinancialReport
 and TargetUnit tests

- Updated test data in `TargetUnitRepository.test.ts` and `WeeklyFinancialReportRepository.test.ts` to include the new `project_hours` field for improved accuracy in testing.
- Adjusted employee and project data in `WeeklyFinancialReportSorting.test.ts` to reflect changes in project hours and effective revenue calculations.

These modifications enhance the test coverage and ensure alignment with recent data model updates.

Subject: [PATCH 19/21] Refactor test data in WeeklyFinancialReportSorting
 tests

- Removed the `project_hours` field from test data to simplify the structure.
- Updated employee rates to a uniform value for consistency in testing.
- Adjusted project revenue rates and added comments to clarify marginality levels.
- Enhanced sorting tests to verify group order based on marginality and alphabetical criteria.

These changes improve the clarity and reliability of the test suite for weekly financial report sorting.

Subject: [PATCH 21/21] Update TargetUnit interfaces and repository for
 optional project_hours handling

- Made the `project_hours` field optional in the `TargetUnit` and `TargetUnitRow` interfaces to allow for more flexible data handling.
- Refactored the `mapRowToTargetUnit` method in `TargetUnitRepository` to include defensive parsing for numeric values, ensuring that `project_hours` and `total_hours` are correctly processed even if they are null or strings.
- Updated the mapping logic to improve robustness against potential data inconsistencies from the database.

These changes enhance the data model's flexibility and improve the reliability of data processing in the repository.
