100% Compliant

Section 4 • Comprehensive Documentation, Error Buckets & Guided Troubleshooting

Fully satisfies Meta Section 4 criteria with Use Case Taxonomy, Error Taxonomy Buckets, Self-Service Diagnostics, and Meta Bug Reporting guidelines.

4.1 Use Case Taxonomy & Expected Behaviors

Use Case ID	Scenario	Target Audience	Expected System Behavior
UC-01	First-Time DAT Pairing	Apprentice / Field Staff	Bluetooth discovery triggers local Wi-Fi direct prompt to RB Meta 02L0 (). DAT permissions requested ().
UC-02	1-on-1 Expert Mentorship Stream	Apprentice & Mentor	HD hands-free POV video streams to mentor screen with active audio chat and live annotations ().
UC-03	Group / Broadcast Mentorship Stream	Apprentice & Workshop	One-to-many live streaming POV feed with real-time viewer count and chat feed ().
UC-04	Off-Head Fallback Flow	Apprentice	When glasses are taken off or disconnected (), app automatically falls back to mobile rear camera without dropping call.
UC-05	Firmware / App Outdated Flow	All Users	Banner detects stale DAT SDK/Firmware version () and redirects user to Meta AI app for immediate OTA upgrade.

4.2 Error Buckets, Root Causes & Telemetry Debugging Logs

Error Bucket	Trigger Condition / Screen	Expected System Behavior	Debugging Log / Telemetry Captured
ERR_FIRMWARE_OUTDATED	Outdated glasses firmware or SDK v0.8 mismatch ()	Displays "Your glasses need an update to work with this app" with CTA to Meta AI.	app_version, lib_version, glasses_fw_build
ERR_WEARING_NOT_DETECTED	Glasses not on head during stream launch ()	Displays "Put your glasses on your head". Offers fallback to phone camera.	wearing_state: false, telemetry_timestamp
ERR_WIFI_HANDSHAKE_DENIED	User cancels or rejects Wi-Fi join dialog for RB Meta 02L0 ()	Connection fails gracefully. Fallback prompt allows session using phone camera.	wifi_connect_status: denied, ssid: RB Meta 02L0
ERR_CAMERA_PERMISSION_DENIED	User denies DAT camera access consent ()	Displays "Camera permission denied" with Retry and Back options.	camera_permission: false
ERR_APP_UNVERIFIED_DENIED	Unverified third-party app toggle turned off ()	Connect button disabled until user toggles trust switch on ().	dat_unverified_trust: false
ERR_STREAM_START_FAILED	Network or socket timeout during WebRTC init ()	Displays "Cannot start stream" with Retry button.	webrtc_error_code, network_type (5G/Wifi)

4.3 In-App Troubleshooting Diagnostics & Meta Technical Bug Reporting Flow

When video streaming fails, the BuzzNow app provides a 3-tier recovery screen (), guided diagnostic checklist (), and direct Meta bug escalation instructions ().

RECOVERY STEP 1

1. Streaming Failed UI

Critical error modal displaying "Video streaming failed". Provides instant Retry, Check configuration, and Report to Meta choices.

RECOVERY STEP 2

2. Guided Config Checklist

1. Check Power: Ensure glasses are ON
2. Restart Glasses: Power toggle cycle
3. Verify Build: Check latest version CTA
4. Restart App: Reopen BuzzNow
Final Step: Restart smartphone

RECOVERY STEP 3

3. Report to Meta Dialog

Exact path provided to end users for QA logging:
Glasses → Settings → Help & support → Send a report (or Shake phone in Meta AI). Attach tag #BuzzNowDAT.

4.4 Meta AI Shake-to-Report Integration Summary

To assist Meta's QA and engineering teams during dogfooding and the Conditional Release period, BuzzNow users can submit technical reports directly through the Meta AI app using either method:

Method A: Navigation Path

Open Meta AI App $\rightarrow$ Top Left Menu (Two Lines) $\rightarrow$ Settings (Cog Icon) $\rightarrow$ Help & Support $\rightarrow$ Report a Problem.

Method B: Shake-to-Report Gesture

Firmly shake phone while in Meta AI app $\rightarrow$ Select "Report a Technical Problem" $\rightarrow$ Attach mandatory tag #BuzzNowDAT.
