# Resource Allocation - Delta Specification

This delta documents required updates to existing resource allocation behavior for fidelity with explicit month planning.

## MODIFIED Requirements

### Requirement: Month execution comparison target

**Original behavior:** month execution was compared against derived or lifecycle assumptions.

**Updated behavior:** selected month project allocation is compared against explicit project-month planned hours.

#### Scenario: Compare row total to month plan
- **GIVEN** selected month plan for project is 1200h
- **AND** project allocations total 1300h
- **THEN** project row variance is +100h
- **AND** row status is `OVER`

#### Scenario: Blank month plan comparison
- **GIVEN** selected month has no plan value set
- **AND** project allocations total 50h
- **THEN** comparison target is 0h
- **AND** row status is `OVER`
- **AND** allocation remains allowed

### Requirement: Bulk allocation behavior

**Original behavior:** all-or-nothing transaction semantics.

**Updated behavior:** valid items SHALL be saved even if some items fail.

#### Scenario: Partial bulk success
- **WHEN** 10 allocation items are submitted and 2 fail validation
- **THEN** 8 valid items are persisted
- **AND** failed items return per-index validation errors
- **AND** response includes summary created/failed counts

### Requirement: Untracked execution semantics

**Original behavior:** untracked support was ambiguous/incomplete.

**Updated behavior:** `team_member_id = null` is valid and treated as untracked effort.

#### Scenario: Untracked counted in project, excluded from capacity
- **WHEN** untracked allocation exists for selected month
- **THEN** project totals include it
- **AND** member capacity/utilization computations exclude it
