# Project Plan: Enterprise Intelligence Final Polish (V6)

## Overview

Resolve the `KeyError: True` and duplicate widget issues to ensure a stable, production-ready dashboard.

## Execution Steps

### Phase 1: Bug Fixes & Optimization [COMPLETED]

- [x] Fix `KeyError: True` in metric calculations by using explicit checks for 'Global' vs 'Country' filtering.
- [x] Remove duplicate sidebar code sections.
- [x] Ensure every widget has a unique `key=` argument to prevent `DuplicateElementID` errors.
- [x] Standardize 1.5x elasticity logic for the Market Discount predictor.

### Phase 2: Visual & Logic Alignment [COMPLETED]

- [x] Sync metrics, graphs, and heatmaps with both historical filters and simulation sandbox.
- [x] Update BI insights to reflect latest slider parameters.
- [x] Verify data loading robustness with try-except blocks.

### Phase 3: Final Verification [COMPLETED]

- [x] Verified all Phase 1-6 features are present and functional.
- [x] Ensured no graphs or layout elements were degraded during fixing.
