Quiet voice sessions now check in once after 15 seconds and close after 30 seconds, with bounded grace for speaking, typing and pending answers. Short, unhurried opening replies adapt to validated independent speech, and Help immediately simplifies delivery. Safe server diagnostics and specific error categories make failures easier to diagnose and recover from.

This branch incorporates #49 with its follow-up fix: complete captions are translated, oversized hosted captions show a clear limit without a futile retry, and a failed full-caption translation clears an earlier partial meaning. #41, #48, #57 and #61 have already merged. This branch reconciles their main history without changing the tested product code.

Issue #32 and PR #44 are deferred at the owner's request. The new persona/accent additions are removed; existing regional guidance and the current voice remain.

UI/UX changes:

  • Two centered lines beneath the orb read “Ending in 5s” and “Reply to continue,” using existing colors and typography, stable spacing and tabular digits. Text remains scalable, and Android leaves room for Report.
  • One spoken check-in, earlier quiet-session closure, gentler opening pace and more specific follow-up questions change conversation behavior.
  • Error advice distinguishes API credit, rate limits, service, connectivity and hosted helper failures, preserving account/key recovery and safe support references.
  • The meaning size-limit message replaces an ineffective retry. Failed complete translations clear stale partial meanings.

The complete review record includes dependency UX changes and normal/large-text screenshots. Validation records the exact checks and limits.

Validation:

  • 364 server tests with PostgreSQL, no skips; TypeScript check.
  • 98 Swift core tests; all 26 iPhone UI tests in the final rerun.
  • 338 Android unit tests; debug/release lint and builds.
  • All 71 Android UI tests on API 36, and all 71 again on a 16 KB API 35 runtime, including real native WebRTC offer creation.
  • Four final Spanish UI checks at 2× text; 54 Python checks and cross-platform/content parity.
  • Two explicitly approved live iPhone calls: captions, built-in speaker output, closure and audio release passed.
  • Exact v8 bundle checks, matching v7 certificate, v2/v3 APK signature, 16 KB ZIP alignment, release manifest and in-place v7→v8 installation passed. Language settings and completed onboarding persisted.

Final review follow-ups add concurrent/no-slot close logging regression coverage and compare fractional timeout constants. No native app source or release binary changed.

Android preview 8 keeps the existing direct-download configuration. Release notes summarize user outcomes. Bluetooth, cellular handoff, Play-signed login and purchases were not exercised in this run. No server deployment is included. Model pace and pronunciation are not guaranteed by prompt tests.

Refs #55. Includes #49 and supersedes #43; contributor credit is preserved.

Summary by CodeRabbit

  • New Features
    • Preview 8 introduces gentler conversation pacing, quiet-session check-ins, countdown warnings, and clearer session-end explanations.
    • Voice sessions now close after 30 seconds of inactivity, while typing, speaking, and active responses provide bounded additional time.
    • Long captions preserve their full text for translation, with clear guidance when hosted captions exceed the supported limit.
    • Failed typed replies retain drafts and offer improved retry guidance.
  • Bug Fixes
    • Provider errors now show safer, more useful guidance and support references.
    • Added Spanish translations for conversation status and error messages.
  • Chores
    • Android release version updated to Preview 8.

Long assistant passages were sending only the last 2,200 characters to
the meaning helper while caching and displaying the result as a full
translation. Route both clients through MeaningRequest.translationInput.

📝 Walkthrough

Walkthrough

The pull request updates conversation inactivity and pacing across Android and iOS, preserves full meaning inputs, adds structured provider and server diagnostics, improves error messages, verifies network recovery, and advances Android release metadata to version 8.

Changes

Conversation behavior

Layer / File(s) Summary
Activity timing and conversation pacing
apps/android/..., apps/ios/...
Voice sessions now use activity state machines, bounded grace periods, check-ins, warnings, inactivity closure, and adaptive delivery guidance.
Typed replies and inactivity UI
apps/android/..., apps/ios/...
Typed input records activity. The UI displays inactivity countdowns and handles oversized-caption errors without retry.
iOS network recovery verification
apps/ios/App/LiveTransport.swift, apps/ios/App/RootView.swift, apps/ios/UITests/MuralUITests.swift
The recovery timeout defaults to eight seconds. Simulator checks cover teardown, reconnection, and timeout behavior.

Captions and provider errors

Layer / File(s) Summary
Full translation inputs and hosted limits
apps/android/..., apps/ios/...
Meaning requests preserve complete captions. Oversized hosted captions fail before dispatch, and failed partial meanings are not cached or retained.
Provider failure classification and client messaging
apps/android/..., apps/ios/...
HTTP failures use bounded parsing, sanitized codes and references, classified failure kinds, and distinct recovery messages.

API diagnostics

Layer / File(s) Summary
Diagnostic contracts and sanitization
services/api/src/diagnostics.ts, services/api/src/diagnostic-error-codes.ts
The API defines diagnostic events, references, failure classification, bounded metadata, and sink isolation.
Request and provider integration
services/api/src/app.ts, services/api/src/main.ts, services/api/src/*provider*, services/api/compose.yaml
Requests, provider calls, startup, background work, and container logs use structured diagnostics.
Hosted voice lifecycle diagnostics
services/api/src/hosted-voice.ts, services/api/tests/hosted.test.ts
Hosted voice records durable close requests and validates duplicate suppression, provider-attach failures, settlement, and reservation handling.

Android release and validation

Layer / File(s) Summary
Android version 8 configuration
apps/android/app/build.gradle.kts, release/android/*, scripts/tests/test_check_android_release.py
Android version code and release specifications advance to version 8. Direct version 7 remains historical.
Release and conversation documentation
docs/run-on-android.md, release/android/notes-v8.md, verification/conversation-reliability/*
Documentation records conversation behavior, release notes, validation scope, and release limitations.
Cross-platform parity checks
scripts/check_cross_platform.py, scripts/tests/test_check_cross_platform.py
Cross-platform checks compare fractional session-limit values without truncating decimal literals.

Explanation

The pull request still contains changes with no demonstrated connection to issues #29, #35, #36, #37, #38, or #47. apps/ios/App/LiveTransport.swift adds network-recovery timeout behavior and a lifecycle fixture. Android version changes, release specifications, release verification metadata, and release notes change release management data. The linked issues do not require network-recovery behavior or release version management.

Resolution

Remove the unrelated LiveTransport network-recovery implementation and fixture, and remove the Android version and release-management changes from this pull request. Alternatively, link those changes to separate coding requirements and review them under that scope.

Full details: Docstring Coverage

Explanation

Docstring coverage is 2.14% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 140 functions across 48 files. (3 skipped: 3 unsupported.)

In `@release/android/README.md`:
- Line 9: Update the README table entry to remove the duplicated “direct,”
changing the description to “historical direct distribution” while preserving
the rest of the release guidance unchanged.

In `@scripts/check_cross_platform.py`:
- Around line 298-299: Update the idleVoiceSeconds and IDLE_VOICE_SECONDS
regexes used by the cross-platform checker to capture the complete numeric
literal, including an optional fractional component, so values such as 30.5 are
preserved for comparison; add a regression test covering mismatched decimal
values.

In `@services/api/src/hosted-voice.ts`:
- Line 374: Update requestClose to use the result of its database update to
detect when close_requested_at transitions from NULL to non-NULL, and emit
voice_close_requested for that transition even when this.slots has no entry.
Retain the existing slot closeLogged guard for in-memory sessions and avoid
duplicate diagnostics for already-requested closes.
