Oversized File Inventory and Split Plan

Scope: source files (.ts, .tsx, .js, .jsx) with more than 400 lines. Binary assets, lockfiles, and generated artifacts are excluded because they are not refactor targets. Files under 300 lines are out of scope and will not be split unless a clear modularization need emerges later.

Method: rg --files + line count as of 2026-01-25.

Example split pattern: a 900-line screen becomes a screen container (app/ route or features/<feature>/<Screen>.tsx) plus UI subcomponents (features/<feature>/components), hooks (features/<feature>/hooks), services (features/<feature>/services), and shared helpers (utils).

Inventory (>= 401 lines)

Notes

• No files under 300 lines are scheduled for splitting at this stage.
