… HTTP 401 Honest correction. My earlier 'Gemma 4 is ungated' claim was based on a stale web-search hit that reported gated=false. Re-tested with curl: GET https://huggingface.co/google/gemma-4-E4B-it-GGUF/resolve/main/ gemma-4-e4b-it-Q4_K_M.gguf -> HTTP/2 401 'Invalid username or password.' Google's official repo still requires HF login + terms acceptance even though the weights themselves are Apache 2.0. Anonymous downloads are rejected at the resolve endpoint. Users were correctly seeing: 'Gemma 4 download paused — Hugging Face refused the request (HTTP 401)' Fix: redirect downloads to the community mirrors which DO allow anonymous fetches (verified 302 -> CDN on a clean curl): primary : https://huggingface.co/unsloth/gemma-4-E4B-it-GGUF fallback : https://huggingface.co/ggml-org/gemma-4-E4B-it-GGUF fallback : https://huggingface.co/bartowski/google_gemma-4-E4B-it-GGUF These hold the IDENTICAL model bytes under the same Apache 2.0 license. Unsloth is the most-downloaded Gemma GGUF publisher; ggml-org is the llama.cpp upstream community; bartowski is a long-running, trusted quant-pack maintainer. * lib/services/gemma_model_manager.dart - modelDownloadUrl points at Unsloth (anonymous fetch ok). - New modelDownloadFallbackUrls const w/ ggml-org + bartowski. - downloadModel() now iterates over [primary, ...fallbacks] and fails over on 401/403/404/429. Other HTTP errors bubble immediately so the caller sees a clean message. - Refactored the actual byte-streaming into _downloadFromUrl() so each candidate URL gets the full resumable-with-Range treatment. - Error copy no longer claims the model is 'Apache 2.0 + ungated' — it correctly explains the mirror failed + the next will be tried. - hfModelCardUrl points at the Unsloth model card (matches the URL we actually download from, so 'View model card' opens cleanly). Verification: ✅ curl -sI https://huggingface.co/unsloth/gemma-4-E4B-it-GGUF/ resolve/main/gemma-4-E4B-it-Q4_K_M.gguf -> HTTP/2 302 -> Location: cas-bridge.xethub.hf.co/... (anonymous fetch succeeds, redirects to CDN). ✅ flutter analyze -> 0 issues across the workspace. ✅ flutter test -> 17/17 passing. ✅ flutter build apk --debug -> 254 MB APK produced in 13 s.

- Retry transient ClientException/connection-closed up to 5x per mirror with Range resume, then fail over across Unsloth/ggml-org/bartowski. - User-facing errors strip long signed CDN URLs from the banner. - Tap Gemma banner to retry; auto-retry on Wi-Fi after failed state. - Remove duplicate StatusIndicatorBar from Safety Tools tab (kept in app bar).

Critical fix — SOS stuck after restart
Root cause:
sos_activein SharedPreferences restoredSOSPhase.activeon every cold start with no way to exit.Fix:
endSosSession()— full teardown (prefs, wake lock, beacon, mesh, family publish, notification)sos_activeinstead of re-entering full-screen SOSUI polish (iOS / liquid glass)
RoadSosGlassPanel+liquid_glass_easydependency for future lens effects)Family Circle
