In `@apps/android/app/src/main/java/chat/mural/core/Languages.kt`:
- Line 224: Extend CaptionWords segmentation to handle Thai text without
whitespace, producing separate lookup values for individual words while
preserving existing behavior for other languages. Update the language
definitions at apps/android/app/src/main/java/chat/mural/core/Languages.kt:224
and apps/ios/Core/Languages/LanguageModule.swift:30 so Thai uses the new
segmentation, and add Android and iOS tests verifying distinct lookup values for
Thai words.
In `@apps/android/app/src/main/java/chat/mural/MuralViewModel.kt`:
- Around line 609-624: Update selectAIProvider to invalidate previously accepted
AI consent whenever the provider changes, using the shared AI_CONSENT_VERSION in
the existing request guards so voice and text requests require renewed consent
for the newly selected provider.
In `@apps/android/app/src/main/java/chat/mural/network/APIClient.kt`:
- Around line 145-150: Update the Gemini response handling in the Android API
client to require the first candidate’s non-empty finishReason to equal STOP
before returning text; otherwise throw APIException.Incomplete. Add
finishReason:"STOP" to the Android success fixture and apply the equivalent
validation in the iOS APIClient response path.
In `@apps/android/app/src/main/java/chat/mural/network/GeminiLiveTransport.kt`:
- Around line 150-163: Update setupMessage and the corresponding setup-message
builder on both platforms to enable Gemini contextWindowCompression and
sessionResumption for supported sessions longer than 15 minutes. Track and
retain the latest resumption handle, handle goAway notifications, and reconnect
using that handle so conversation state survives periodic WebSocket resets while
preserving existing session duration behavior.
In `@apps/android/app/src/main/java/chat/mural/ui/SettingsScreen.kt`:
- Around line 365-367: Update the liveSession.topics rendering in SettingsScreen
so every topic with a non-blank searchEntryPointHTML produces its own
GoogleSearchSuggestions item instead of stopping at firstOrNull(). Iterate
through topics, preserve the existing filtering, and assign each item a stable
topic-specific key such as using topic.id.
- Around line 158-170: Remove the provider-independent voice estimate row from
the SettingsScreen usage section, or replace it with a provider-aware
calculation based on each archived SessionRecord and its applicable model rate;
do not display the existing UsageSummary.of voiceEstimate for Google AI Studio
or mixed-provider histories.
In `@apps/android/app/src/main/res/values-es/strings.xml`:
- Line 247: Update the consent_ai_summary strings in both Spanish and English
resources to explicitly disclose that the text of topic searches is sent to the
selected AI provider, while preserving the existing audio, selected-text,
purpose, and retention wording.
In `@apps/ios/App/APIClient.swift`:
- Around line 115-118: Deduplicate normalized web search queries before
calculating usage.searches: update the searchQueries construction in the
surrounding search usage flow to use a Set after trimming and filtering empty
strings, while preserving the existing fallback count when sources are present.
In `@apps/ios/App/LibraryViews.swift`:
- Line 402: Remove the “Voice estimate” LabeledContent and its
provider-independent $0.05/min calculation from the session history view; do not
replace it unless costs are computed per session using that session’s provider
and applicable model rate.
- Around line 199-200: Update updateUIView(_:context:) to compare and store the
HTML through context.coordinator.loadedHTML rather than view.accessibilityValue,
while preserving the existing reload guard and loadHTMLString flow; add the
loadedHTML property to Coordinator.
In `@apps/ios/App/OnboardingView.swift`:
- Line 188: Update AIProcessingConsent consent handling so changing
selectAIProvider cannot reuse consent granted under the previous provider scope;
either bump AIProcessingConsent.version to 2 so existing version-1 consent is
invalidated, or store consent per provider and require renewed consent after
provider changes.
In `@docs/google-ai-studio.md`:
- Line 12: Update the documentation statement about Google AI Studio to
acknowledge that Live voice requires microphone runtime permission, while
retaining the claims about no Mural API, database migration, or production
deployment changes.
In `@README.md`:
- Line 92: Update the README credential-storage statement to use
platform-neutral wording or explicitly mention both Apple Keychain and Android
Keystore/private encrypted preferences, while preserving the existing claims
about export exclusion and provider-only transmission.
