Problem Several modules under frontend/src/helpers/ contain non-trivial logic but have no unit tests. They are imported across many parts of the app, so silent regressions in them (e.g., a corrupted localStorage payload, a container-fallback bug, an off-by-one in the dedup logic) are hard to spot. The umbrella under #931 (Stories for components) covers visual / Storybook gaps; this issue tracks the same gap for the pure-logic helper modules.
