i18n Coverage Audit — Ideony Monorepo

Date: 2026-04-20
Scope: apps/mobile/ (Expo/React Native, i18next) + apps/api/src/ (NestJS, nestjs-i18n)
Locales: IT (default) + EN

1. Mobile — Missing t() Wraps

Raw user-visible strings not wrapped in t(). Fallback strings (2nd arg to t()) are excluded — those are acceptable defaults.

File	Line	Raw String	Suggested Key
app/(welcome)/continue.tsx	80	"oppure" (Italian divider)	common.or_divider
app/(welcome)/continue.tsx	87	placeholder="Email"	auth.email_placeholder
app/(welcome)/continue.tsx	100	accessibilityLabel="Email"	auth.email_placeholder
app/(welcome)/continue.tsx	157	placeholder="000000"	auth.otp_placeholder
app/(welcome)/continue.tsx	169	accessibilityLabel="OTP code"	auth.otp_accessibility
components/chrome/Header.tsx	28	accessibilityLabel="Notifications"	common.notifications
components/chrome/Header.tsx	38	accessibilityLabel="Profile avatar"	common.profile_avatar
components/professional/HeroCarousel.tsx	84	accessibilityLabel="Indietro" (Italian!)	common.go_back
components/professional/HeroCarousel.tsx	95	accessibilityLabel="Condividi" (Italian!)	common.share
components/AvailabilityEditor.tsx	169	placeholder="09:00"	calendar.time_start_placeholder
components/AvailabilityEditor.tsx	180	placeholder="18:00"	calendar.time_end_placeholder
app/(professional)/onboarding/profile.tsx	163	placeholder="0"	(numeric — low priority)
app/(professional)/onboarding/pricing.tsx	238	placeholder="25"	(numeric — low priority)
app/(professional)/onboarding/pricing.tsx	278	placeholder="80"	(numeric — low priority)

Critical: HeroCarousel.tsx hardcodes Italian strings — will always display Italian regardless of user locale.

2. Mobile — Dead Keys (defined but never referenced)

Keys present in lib/i18n/en.json with no t("ns.key") usage found in source.

Note: a thorough dead-key scan requires exhaustive grep of all key paths. The following are confirmed dead after cross-referencing all t() call sites found in app/**/*.tsx and components/**/*.tsx.

Namespace	Key(s)	Notes
bookings	empty_title, empty_subtitle	Code calls bookings.emptyTitle / bookings.emptySubtitle (camelCase) — snake_case versions unreachable
sos	button_label	No component calls t("sos.button_label")
home	greeting_anonymous	No call site found
professional_card	entire section	No t("professional_card.*") calls found in scanned files — verify if used elsewhere

---

3. Mobile — Undefined Keys Referenced

Keys called via t() that do not exist in lib/i18n/en.json. These silently render the key string at runtime.

SOS module (7 keys)

File	Key
app/sos/index.tsx	sos.describe_problem_placeholder
app/sos/[id]/cancelled.tsx	sos.no_candidates_title
app/sos/[id]/cancelled.tsx	common.go_home
app/sos/[id]/complete.tsx	common.go_home
components/sos/CandidateCard.tsx	sos.etaMinutes
components/sos/CandidateCard.tsx	sos.selectCandidate
components/sos/CandidateCard.tsx	sos.min

SOS DispatchStatusBar (5 keys)

File	Key
components/sos/DispatchStatusBar.tsx	sos.statusSearching
components/sos/DispatchStatusBar.tsx	sos.statusDispatching
components/sos/DispatchStatusBar.tsx	sos.statusDispatchingWait
components/sos/DispatchStatusBar.tsx	sos.statusWaitingAccept
components/sos/DispatchStatusBar.tsx	sos.statusTracking

Bookings (naming mismatch — 3 keys)

File	Key (called)	Key (in JSON)
components/empty/BookingsEmpty.tsx	bookings.emptyTitle	bookings.empty_title
components/empty/BookingsEmpty.tsx	bookings.emptySubtitle	bookings.empty_subtitle
components/empty/BookingsEmpty.tsx	bookings.emptyCta	(absent — no snake_case either)

Professional profile (5 keys)

File	Key
components/professional/StickyBookBar.tsx	professional_profile.starting_price
components/professional/StickyBookBar.tsx	professional_profile.book_cta
components/professional/SectionTabs.tsx	professional_profile.tab_reviews
components/professional/SectionTabs.tsx	professional_profile.tab_certifications
components/professional/SectionTabs.tsx	professional_profile.tab_area

Review screen (2 keys)

File	Key
app/review/[bookingId].tsx	review.hero_subtitle
app/review/[bookingId].tsx	review.comment_placeholder_detail

Consumer home (4 keys)

File	Key
app/(consumer)/index.tsx	home.heroTitle
app/(consumer)/index.tsx	home.heroSubtitle
app/(consumer)/index.tsx	home.categoriesTitle
app/(consumer)/index.tsx	home.searchPlaceholder

Total mobile undefined keys: 26

4. API — Missing t() Wraps

All user-facing error messages in apps/api/src/ should use t(key, fallback) via src/common/i18n.helper.ts. The following modules had hardcoded English strings thrown directly without t():

Scan found all error throws use t() via the helper — no bare hardcoded error strings identified in scanned modules. This section passes.

---

5. API — Dead Keys

Keys in apps/api/src/i18n/en/common.json with no t("key") call site found.

Section	Key	Notes
notification	entire section (6 keys)	sos_request, booking_confirmed, booking_cancelled, payment_received, review_prompt, service_reminder — no t("notification.*") calls found in API source
booking	profile_exists	No t("booking.profile_exists") call found
onboarding	p_iva_required	No t("onboarding.p_iva_required") call found (may be used — verify)

---

6. API — Undefined Keys Referenced

The t() helper in src/common/i18n.helper.ts prepends common. to keys. JSON uses snake_case; some call sites use camelCase → always falls back to English.

camelCase / snake_case mismatches (key exists in JSON but under different casing)

File	Key called	Key in JSON	Effect
modules/credentials/credentials.service.ts	credential.notFound	credential.not_found	Always English fallback

Keys entirely absent from JSON (missing sections)

File	Key(s) called	Missing section
modules/quotes/quotes.service.ts	quotes.not_found, quotes.forbidden, quotes.accepted_only, quotes.already_responded, quotes.professional_mismatch, quotes.invalid_status, quotes.consumer_only, quotes.booking_not_found	quotes section absent
modules/verification/verification.service.ts	verification.profile_not_found, verification.not_found, verification.already_reviewed	verification section absent
modules/sos/sos.service.ts	sos.no_pricing	Key absent from sos section
modules/onboarding/onboarding.service.ts	onboarding.user_not_found	Key absent from onboarding section
modules/onboarding/onboarding.service.ts	onboarding.portfolio_image_not_found	Key absent
modules/onboarding/onboarding.service.ts	onboarding.portfolio_image_forbidden	Key absent
modules/credentials/credentials.service.ts	credential.notPending	Key absent

Total API undefined keys: 15 keys across 4 modules
Critical: entire quotes (8 keys) and verification (3 keys) sections missing — all errors in these modules display English only regardless of user locale.

7. Parity Gaps — EN ↔ IT

Mobile (lib/i18n/en.json vs lib/i18n/it.json)

Keys present in EN but missing from IT:

Namespace	Missing Keys
auth	welcome_heading, continue_cta, continue_with_apple, continue_with_google, continue_with_facebook, otp_title, verify_cta, new_user_prompt, register_link

9 keys missing from IT mobile JSON. The entire authentication flow will display English strings when the device is set to Italian.

Keys present in IT but missing from EN: none identified.

API (src/i18n/en/common.json vs src/i18n/it/common.json)

IT and EN API files are fully parified — identical key sets. No gaps.

8. Coverage Summary

Mobile

IT parity gaps	9	Entire auth section missing from IT
Dead keys (defined, unreferenced)	~6	bookings snake_case, sos.button_label
Mobile i18n health	Poor	SOS feature and professional profile ~0% translated at runtime

API

Category	Count	Notes
Undefined keys	15	quotes + verification sections entirely absent
