Executive Summary

Codebase	Source Files	Files With Tests	Coverage Level	Risk
Python v1	59	18	~30% file coverage	High
Rust workspace	293	283 (inline #[cfg(test)])	~97% file coverage	Low
Rust integration tests	--	16 test files	Moderate	Medium
Mobile (React Native)	71	25	~35% file coverage	Medium
Firmware (ESP32 C)	16 .c files	3 fuzz targets	~19% file coverage	Critical

Total source files across all codebases: ~439 Files with some form of test coverage: ~339 Estimated overall file-level coverage: ~77%

Key finding: The Rust codebase has excellent inline test coverage (97% of source files contain #[cfg(test)] modules). The critical gaps are concentrated in Python services/infrastructure (0% coverage on 41 source files), firmware C code (13 of 16 source files untested), and mobile utility/navigation layers.

8. Risk Assessment Methodology

Risk scores (0.0 - 1.0) were calculated using:

Factor	Weight	Description
Code complexity	30%	LOC, cyclomatic complexity, dependency count
Security criticality	25%	Authentication, authorization, network boundary, input parsing
Change frequency	15%	Git commit frequency on the file
Blast radius	15%	How many other components depend on this code
Data sensitivity	10%	Handles PII, credentials, or firmware integrity
Testability	5%	How difficult the code is to test (hardware deps, async, etc.)

Files scoring above 0.85 are flagged as Critical, 0.70-0.85 as High, 0.50-0.70 as Medium, below 0.50 as Low.
