| Feature | PRD Priority | Status | Evidence / Notes |

|---|---|---|---|

| Classroom scene narration | P0 | 🟡 | Capture/UI and Edge invocation exist, but successful client response is fixed text; hardware gesture delivery is unverified |

| Whiteboard & text reading (OCR) | P0 | 🟡 | Read prompt exists; no OCR engine, hardware double-tap callback, or returned-model-text path |

| Classroom/slides mode + notes PDF | P0 | 🟡 | Bluetooth service has a branch/PDF helper; active Scene UI does not route its Classroom action to that branch |

| Emotion detection | P0 | 🟡 | Prompt and face-name injection exist; Edge response is discarded and no hardware left-double-tap callback was found |

| Person identification | P0 | 🟡 | FaceNet compares against Supabase-fetched CSV embeddings; not local-only, model failures are unsafe, and fallback answer is fixed text |

| Academic content filter | P0 | 🟡 | Enforced via prompts (academic tone, constrained outputs); no separate filter layer yet |

| Academic Mode (level vocabulary) | P0 | ✅ | Toggle on Home; appends academic-level instruction to prompts |

| Student voice persona | P1 | 🟡 | Four presentation companions + local selection; no distinct voice/prompt mapping. Active Scene helper retains legacy child filtering |

| Activity detection | P1 | 🟡 | Covered by scene/classroom prompts; no dedicated mode |

| Object identification | P1 | 🟡 | Via chat ("Be My Eyes") free-form questions |

| Hallway & navigation alerts | P1 | 🟡 | `HallwayNavigationService` (≤12-word cues) exists; not surfaced in UI |

| VLM switcher | P1 | 🟡 | `VisionService.VlmProvider` enum (moondream/llava/GPT4V) in legacy dashboard; not in student UI |

| Teacher dashboard | P1 | 🟡 | PIN-gated face registration + `SupabaseDashboardRepository` + FERPA audit logs; no web portal |

| Parent dashboard | P1 | ⏳ | Schema/planning only |

| Offline mode | P2 | ⏳ | PRD roadmap; `sessions.offline_mode` column exists; context mesh notes "Offline mode: Gemma 3" struck through |

| Multi-language support | P2 | 🟡 | Sarvam translate/TTS for Indic languages in speak path; UI English-only |

| Weekly learning summary | P2 | ⏳ | Today's Story covers daily; weekly report not built |

| Feature | Status | Notes |

|---|---|---|

| Glasses gestures (single/double tap, hold) | 🟡 | Callable handlers exist; no DAT gesture callback registration was found |

| One-shot voice commands (long-press) | 🟡 | Android speech service exists; no verified DAT trigger or source broadcaster for documented commands |

| "Hey Netra" wake word | ❌ | WakeWordService removed per user request; receiver hooks remain; PRD/JIRA AC still open |

| AI chat w/ image+video ("Be My Eyes") | 🟡 | Chat/media UI and Edge invocation exist, but client replaces responses with fixed success text |

| Lecture notes + AI summary | 🟡 | Device transcript and Edge invocation exist; summary response is fixed success text |

| Today's Story recap | ✅ | Timeline + "Read My Day Out Loud" |

| Emergency SOS | 🟡 | EmergencyAlertManager service only; no trigger, GPS/summaries TODO |

| Smart auto-capture / battery saver | 🟡 | SmartCaptureController (2s/10s intervals); toggle in settings; scene-change detection TODO |

| Recess/playground social | 🟡 | RecessSocialService exists; not surfaced in UI |

| Item | Status | Notes |

|---|---|---|

| Supabase auth (email, OTP, Google) | ✅ | gotrue-kt; deep links `threenetra://` |

| Firebase → Supabase migration | ✅ | "Phase 5 complete, Firebase disconnected" (Mayukh log, Jun 2026) |

| AWS SAM AI gateway | 🟡 | Routes are implemented but `AwsBackendService` is unreferenced by production app code; deployment workflow omits its OpenAI parameter |

| Encrypted local face embeddings | 🟡 | Utility exists but is unreferenced; active enrollment/matching uses Supabase |

| Realtime settings sync | ✅ | Realtime channel on `student_settings` |

| GitHub Actions APK build | ✅ | Pushes to `prod` build and upload a debug APK; no test/lint/release signing gate |

| Face recognition w/ local embeddings (README roadmap) | ✅ | Done — README item stale |

| Real-time shared classroom materials | ⏳ | README roadmap |

| E2E testing coverage | ⏳ | README roadmap; unit/instrumented scaffolding only |

| Teacher/parent web portals, My School Subjects | ⏳ | PRD screens not built |

| iOS companion app | ⏳ | PRD mentions iOS/Android; Android only today |

**Meta glass app roadmap:** OCR, face recognition, emotion, campus navigation, multilingual output, dashboards, and offline support are roadmap/document claims. This audit does **not** promote them to delivered: the active AI client returns fixed success text, local-only face storage is unused, and hardware behavior is untested.

**PRD phases:** Treat PRD phases and checkmarks as planning evidence. Source supports partial UI/service scaffolding, not verified delivery of an end-to-end VLM, OCR, gesture, dashboard, or safety-navigation release.

**Q2 epics (org):** Revisit PRD · Redesign UI/UX wireframes · Redesign website (Fable5 Vercel)
