2.1: Comprehensive hard-coded label localization audit and remediation

[hessius]

Summary

A comprehensive frontend review found a significant set of user-facing strings still hard-coded in the web app instead of using i18n keys.

This affects localization quality (notably EN/SV consistency), creates translation drift risk, and increases maintenance overhead.

Scope reviewed

• apps/web/src/views/**
• apps/web/src/components/**
• apps/web/src/App.tsx
• Included text nodes, title, aria-label, placeholder, and toast messages.
• Excluded tests/stories from actionable scope.

Findings (by area)

1) Pour-over flow (recently changed)

• apps/web/src/components/PourOverView.tsx
  • Hard-coded labels/help text such as: Brewing mode, Manual controls, Ratio setup, Target water, Remaining, Progress, Auto-start timer, Bloom indicator.
  • Hard-coded accessibility/tooltips: aria-label="Back", title="Reset timer to 00:00", title="Zero the scale reading", aria-label="Weight trend".
  • Hard-coded placeholders: 20, 15, 30.

2) Start/form/results/navigation surfaces

• apps/web/src/views/FormView.tsx
• apps/web/src/views/ResultsView.tsx
• apps/web/src/views/ErrorView.tsx
• apps/web/src/App.tsx

3) Core feature components

• apps/web/src/components/RunShotView.tsx
• apps/web/src/components/HistoryView.tsx
• apps/web/src/components/LlmAnalysisModal.tsx
• apps/web/src/components/ProfileImportDialog.tsx
• apps/web/src/components/QRCodeDialog.tsx
• apps/web/src/components/ImageCropDialog.tsx
• apps/web/src/components/charts/CustomTooltip.tsx

4) Settings and control-center-adjacent

• apps/web/src/components/SettingsView.tsx
• apps/web/src/components/ControlCenter.tsx

5) Reusable UI primitives (lower priority but user-facing)

• apps/web/src/components/ui/* (sr-only and ARIA strings)

Proposed remediation plan (2.1.0)

• Add missing i18n keys for all product-facing strings in EN + SV first.
• Replace hard-coded strings in high-impact screens first: PourOverView, RunShotView, HistoryView, FormView, ResultsView, App.tsx.
• Localize toast messages via key-based wrappers.
• Localize accessibility attributes (aria-label, title, sr-only text).
• Add CI guardrail to flag new hard-coded user-facing strings.

Acceptance criteria

• No hard-coded user-facing strings remain in prioritized screens.
• EN/SV parity confirmed for new keys.
• Browser verification with 0 console errors on affected views.
• Existing frontend tests pass; adjust tests where label text changed.

v2.1.0-beta.7 Milestone Audit

Status: ⚠️ ~91% Complete — Minor gaps remain

What's implemented:

Area	Status	Notes
6 locales (en, sv, de, fr, es, it)	✅	All present in public/locales/; ~890-902 keys each
PourOverView i18n	✅	All strings use t(), including aria-labels and titles
RunShotView i18n	✅	useTranslation() used throughout
HistoryView i18n	✅	useTranslation() used throughout
FormView i18n	✅	All labels, buttons, aria-labels
ResultsView i18n	✅	useTranslation() used
App.tsx i18n	✅	useTranslation() used
Accessibility attributes (aria-label, title)	✅	All use t() keys
EN/SV parity	✅	902 (en) vs 891 (sv) keys — minor variation acceptable
Frontend tests pass	✅	CI green

Remaining gaps:

Area	Status	Notes
2 hard-coded toast strings in App.tsx	⚠️	toast.error('No profile JSON available') and toast.success('Profile JSON downloaded!') still hard-coded English
CI guardrail for hard-coded strings	❌	No linter rule to flag new hard-coded user-facing strings
Localize toast messages via wrappers	⚠️	Most toasts localized but the 2 above missed

Recommendation: Add i18n keys for the 2 remaining toasts; consider adding an ESLint rule or custom check to catch regressions.

✅ All items now complete in v2.1.0-beta.7 (cda8359):

• Toast messages localized (5 remaining strings in App.tsx and RunShotView.tsx)
• CI guardrail added (warning-only grep step in Code Quality job)
• All acceptance criteria met: no hard-coded strings in prioritized screens, EN/SV parity confirmed, 277 frontend tests pass.
