The objective is to make color assignment deterministic and stable for each tool name across updates, re-renders, and page reloads, while keeping the implementation simple and testable. + +## Scope and Deliverables +- Implement deterministic tool-name-to-color mapping logic in frontend chart rendering code. +- Persist color assignments in browser local storage so mappings survive reloads. +- Ensure all tool-usage chart views consume the same mapping utility. +- Add unit tests for deterministic mapping and persistence behavior. +- Add integration-style frontend behavior test for stable colors when tool set changes. + +Out of scope: server-side persistence and custom user-defined palettes. + +## Acceptance Criteria +- Given a tool name seen previously, the same color is used on every subsequent refresh. +- Adding or removing other tool names does not change previously assigned colors. +- Mapping is deterministic for an empty cache and deterministic after reload using cached values. +- Existing chart rendering remains functional with no JS runtime errors. +- Test suite covering new utility and chart update path passes. + +## Test-First Plan +1.
