Fill coverage gaps and lock in behavior for the Activities screen and
app/nav (Sidebar) domain (plan task B-D6). All four domain src files
(screens/Activities.tsx, api/activities.ts, App.tsx, components/Sidebar.tsx)
now at 100% stmts/branch/funcs/lines.
- Activities.test.tsx: insole-type toggle select/deselect (both branches),
reduced-subset create, add disabled when no types, edit insole types,
cancel-without-save, empty-types-defaults-all editor, empty state,
error-falls-back-to-empty, and the create->edit types->reorder->delete
lifecycle test.
- Sidebar.test.tsx (new): brand + nav links + email, active-route highlight,
end-match keeps Live inactive off-root, nav click switches screen + moves
highlight, Uitloggen calls signOut, email hidden without useMe data.
- Activities.tsx: three /* c8 ignore next */ annotations on the defensive
early-return guards in handleAdd/handleSave/handleMove (each mirrored by a
disabled button, so unreachable via the UI). Comment-only, no behavior change.
No bugs found — the domain code was already correct; the tests lock it in.
