Medium Findings

ID	Area	Current evidence	Recommendation
M01	Request transform size	lib/request/request-transformer.ts is 1186 lines and owns model normalization, fast-session defaults, input filtering, prompt injection, and outbound body shaping.	Split only when a behavior change forces touching multiple subdomains.
M02	Fetch helper size	lib/request/fetch-helpers.ts is 1104 lines and combines URL rewrite, auth refresh, error classification, headers, and request transformation wrappers.	Extract error classification and retry response mapping behind tests.
M03	Storage implementation size	lib/storage/load-save.ts, keychain.ts, and worktree-lock.ts are the largest storage modules.	Keep the facade stable and split only around concrete bug fixes.
M04	Coverage branch floor	npm run test:coverage showed broad branch coverage at 71.6% and index.ts branch coverage at 51.21%, below the former aspirational thresholds.	Keep the gate executable at the current baseline and raise branch floors with focused tests in later PRs.
