## ADDED Requirements

### Requirement: Log hours worked
The system SHALL allow team members to log actual hours worked per project per month.

#### Scenario: Log hours for current month
- **WHEN** a team member logs 35 hours worked on "Project X" for February 2026
- **THEN** the system creates an actuals record
- **AND** the system associates the hours with the team member, project, and month

#### Scenario: Cannot log negative hours
- **WHEN** attempting to log -5 hours
- **THEN** the system rejects the request with validation error "Hours logged must be greater than or equal to 0"

#### Scenario: Cannot log hours for future months
- **WHEN** attempting to log hours for a month that hasn't started yet
- **THEN** the system rejects the request with validation error "Cannot log hours for future months"

### Requirement: Update logged hours (incremental)
The system SHALL allow team members to update previously logged hours using incremental updates.

#### Scenario: Incremental weekly updates
- **WHEN** a team member logs 10 hours in week 1 of February
- **AND** logs an additional 8 hours in week 2 of February
- **AND** the system updates the total to 18 hours for February
- **THEN** the system accumulates the hours for the monthly aggregate
- **AND** the system preserves all notes from each update

### Requirement: View actuals summary with variance
The system SHALL display actual hours worked in a matrix view showing allocated, actual, and variance data.

#### Scenario: View monthly actuals matrix
- **WHEN** a manager views actuals for February 2026
- **THEN** the system displays projects as rows and team members as columns
- **AND** each cell shows:
  - **Allocated hours** (from allocation records)
  - **Actual hours** (from actuals records)
  - **Variance %** = ((Actual - Allocated) / Allocated) × 100
  - **Variance indicator**: GREEN (≤5%), YELLOW (5-20%), RED (>20%)

#### Scenario: Show variance indicators
- **WHEN** viewing the actuals matrix
- **THEN** cells are color-coded based on variance:
  - GREEN: Within ±5% of allocation (on track)
  - YELLOW: 5-20% variance (attention needed)
  - RED: >20% variance (significant deviation)

### Requirement: Cannot log hours to inactive projects
The system SHALL prevent logging hours to projects in "Done" or "Cancelled" status (configurable via global setting).

#### Scenario: Attempt to log hours to done project
- **WHEN** attempting to log hours for a project with status "Done"
- **AND** the global system configuration `allow_actuals_on_inactive_projects` is false
- **THEN** the system rejects the request with error "Cannot log hours to completed projects"

#### Scenario: Allow logging to done project if configured
- **WHEN** the global configuration `allow_actuals_on_inactive_projects` is true
- **AND** a team member logs hours to a "Done" project
- **THEN** the system accepts the hours (for edge cases where work continues after project closure)

### Requirement: Actuals data entry is manual
The system SHALL support manual entry of actual hours without integration to time-tracking tools (MVP).

#### Scenario: Manual monthly entry
- **WHEN** a team member enters actual hours worked via the web interface
- **THEN** the system accepts the input without requiring integration with external time-tracking systems

#### Scenario: No automated time import
- **WHEN** viewing actuals entry interface
- **THEN** the system does not provide options to import from Jira, Harvest, Toggl, or other time-tracking tools (deferred to Phase 2)

### Requirement: Track actuals notes
The system SHALL allow optional notes when logging hours.

#### Scenario: Log hours with notes
- **WHEN** a team member logs 40 hours with notes "Focused on API development and bug fixes"
- **THEN** the system stores the notes alongside the hours logged

#### Scenario: View notes in matrix
- **WHEN** viewing the actuals matrix
- **THEN** clicking on a cell shows the history of logged hours with timestamps and notes
