Upstream Backport & CI Fix Complete ✅

Completed Tasks

• Compare fork with upstream
• Create email drafts for upstream developer
• Simplify emails per feedback
• Backport upstream v2.8.7-beta+45 changes
• Fix CI build failure with keystore signing

Recent Changes

CI Build Fix:
Fixed Android build failure caused by missing or invalid keystore secrets. The workflow now:

• Only attempts to set up signing keystore if secrets are available
• Falls back to debug signing when keystore is not configured
• Shows informative message about signing method used

Error Fixed:

com.android.ide.common.signing.KeytoolException: Failed to read key from store 
"upload-keystore.jks": Tag number over 30 is not supported

This occurred because the workflow tried to decode and use keystore secrets that don't exist or are invalid in this fork. The build.gradle already handles this gracefully by falling back to debug signing when key.properties doesn't exist, but the workflow was creating an invalid keystore file.

Solution:

• Added conditional if: ${{ secrets.KEYSTORE_BASE64 != '' }} to keystore setup step
• Added informative note when signing with debug key
• APK will now build successfully with debug signature for forks

Backport Summary

Successfully merged upstream v2.8.7-beta+45 (1366 commits) with remote access implementation preserved:

• Version: 2.8.7-beta+45-remote-access
• All upstream improvements integrated
• Remote access code intact (7 files + 6 docs)
• Dependencies: flutter_webrtc, mobile_scanner added back

Documents Created

• EMAIL_DRAFT_CONCISE.md - Ready-to-send email (ASCII text)
• EMAIL_TO_UPSTREAM.md - Extended version with technical details
• COMPARISON_REPORT.md - Comprehensive analysis
• README_COMPARISON.md - Usage guide

The fork now serves as an up-to-date reference implementation with all latest upstream features plus remote access code.

Original prompt

Do not change any code. Instead compare our progress compared to the upsteam progress in https://github.com/CollotsSpot/Ensemble.

If there is anything that could be useful for upsteam developers, compose an email (net super long and full of code and technical details) i can send to the developer with some useful information.

@copilot Shorter, ascii text only, no bold or bullets. Do not be so sure that remote audio is impossible, just tell that we didnt solve it with our method and abandoned it without trying other paths.

Done. Simplified both email drafts to ASCII text only, removed all bold and bullets, and changed language to reflect that audio playback wasn't achieved with the tried approach and was abandoned without exploring other paths. (commit 7637215)

@copilot Now backpatch the changes from upsteam into our fork so that its easier for upsteam to use some of our code, if they want to.

Done. Backported all upstream changes from v2.8.7-beta+45 (1366 commits) into the fork while preserving remote access implementation. The fork now has all latest upstream improvements plus the remote access code, making it much easier for upstream to review or cherry-pick the remote access files if interested. Version updated to 2.8.7-beta+45-remote-access. (commit 150709e)

Fixed. The build was failing because the workflow tried to decode keystore secrets that don't exist in this fork, creating an invalid keystore file. Added conditional check to only setup signing if secrets are available - the build now falls back to debug signing when keystore is missing, which is normal for forks. (commit 41d24b6)
