The site now speaks German, French, Spanish, Ukrainian, Russian, Chinese,
Korean and Hindi alongside English — 623 strings per language, 5,607
translations, covering the landing page, the key exchange, the chat, group
calls and every error along the way.
Each locale is a real page at a real URL (/de/, /fr/, …), generated at build
time from locales/*.json. That is the whole point: the app is client-rendered,
so a language that only swaps strings at runtime has no address for a crawler
to index and no link anyone can share. Each page carries its own canonical, a
reciprocal hreflang cluster and translated schema.org.
The URL decides the language, always. A stored preference only applies where
the address does not say, and nothing ever redirects on Accept-Language —
that is how sites become invisible to search engines outside one country.
robots.txt and sitemap.xml did not exist before; both are generated now.
Bugs found on the way, each with a test that would have caught it:
- partner logos used page-relative paths and 404'd from any /xx/ page
- post-build stamped ?v= only into the root shell, leaving locales behind
- "Back online" appeared on every page load, not just after being offline
- update timestamps were hard-coded to US format for every reader
- t() threw on a partial window, taking whole components down with it
Complete the mandatory receiver-consent gate that was wired in the
backend but never connected to the UI callback chain:
- Add the missing onIncomingFileRequest (4th) callback to
setFileTransferCallbacks in app.jsx — its absence caused
handleFileTransferStart to auto-reject every incoming file.
- Remove independent callback registration from FileTransferComponent;
the component was overwriting app-level callbacks on mount and
nulling all four on unmount, silently breaking progress/received/
error handlers whenever the panel was hidden.
- Lift pendingIncomingFiles state to the root component so consent
prompts are shown regardless of panel visibility; auto-open the
panel on incoming request.
- Add getReceivedFileObjectURL / revokeReceivedFileObjectURL on
EnhancedSecureWebRTCManager for download buttons in the panel.
- Update file-transfer-ui-cleanup regression test to match the new
single-owner callback architecture.
- All 14 tests pass; clean production build.
