[codex] Document GameFi QA checklist

[Jim8y]

Summary

• Add a GameFi QA checklist and performance gate for reviewing game dApps before listing or promotion.
• Cover submission evidence, loading/failure states, mobile layout, performance thresholds, wallet integration, optional native capabilities, and platform test matrix.
• Include a reviewer notes template and pass criteria that preserve existing Erik/admin guardrails.

Scope

Part of #76, Task 8: Game QA Checklist and Performance Gate.

This is documentation only. It does not add runtime diagnostics export, runtime blocking, local transaction storage, permission-center behavior, trust bar UI, or third-party game DOM/CSS adaptation.

Validation

• git diff --check
• dotnet build OneGateApp/OneGateApp.csproj -f net10.0-ios -c Debug -p:RuntimeIdentifier=iossimulator-arm64 -p:CodesignKey=- -p:CodesignProvision= -p:ProvisioningType=automatic --nologo
• dotnet build OneGateApp/OneGateApp.csproj -f net10.0-android -c Debug -p:EmbedAssembliesIntoApk=true --nologo
• iOS simulator install/launch/screenshot on OneGate-PR51-iPhone17.
• Android emulator install/launch/screenshot on emulator-5554; MainActivity resumed.

Notes

Build warnings are existing repository/environment warnings: SQLitePCLRaw NU1903 advisories, iOS duplicate ImageAsset warnings, and the local Android JDK path validation warning.

Validation screenshots and notes for this PR:

• Android emulator: installed Debug APK on emulator-5554, launched org.neoorder.onegate/crc64e93af8ff8666345c.MainActivity, and confirmed MainActivity is resumed.
• iOS simulator: installed and launched on OneGate-PR51-iPhone17.
• Screenshot assets are uploaded to GitHub release assets, not committed to the repository.

Pull request overview

Adds an internal documentation checklist to standardize GameFi/game dApp QA reviews prior to listing/promotion, with an explicit performance gate and reviewer evidence requirements aligned with existing guardrails (no committed QA artifacts, no OneGate-side DOM/CSS patching, etc.).

Changes:

• Introduces a GameFi QA checklist covering submission evidence, loading/failure states, mobile layout, wallet integration, and optional native capabilities.
• Defines a performance gate table (timings/long-frame rate/memory/assets) plus pass criteria for listing/promotion decisions.
• Provides a reviewer notes template and a platform test matrix for consistent cross-platform validation.

Review follow-up pushed in 2375b74.

Addressed:

• Performance gate now labels PSS as Android-only.
• Pass criteria now says performance metrics instead of implying memory is defined identically on both platforms.

Validation:

• Documentation-only change; git diff --check passed.

Do not include unaccepted APIs in the documentation.

[Jim8y]

Addressed Erik's review request.

Changes:

• Removed the optional native capability list from the QA checklist.
• Replaced it with guidance that proposed/unaccepted OneGate APIs must not be required, documented, or tested as listing criteria.
• Updated the reviewer template and pass criteria to record unaccepted API needs as separate proposals instead of treating them as QA requirements.

Validation: docs-only change; git diff --check passed.

[Jim8y]

Addressed Erik's review feedback in b22d9bc.

Change:

• Removed the onegate-game.json preflight requirement from the GameFi QA checklist.
• Removed the optional manifest URL from required review evidence.

Validation:

• Confirmed the document no longer references onegate-game.json.
• git diff --check passed.

This is a documentation-only PR, so no simulator screenshot was captured for this update.

[Jim8y]

Current head already addresses the open documentation feedback.

Checked in this pass:

• No remaining onegate-game.json reference; the checklist now uses generic metadata/submission wording instead of inventing a new manifest file.
• Android memory metric is explicitly labeled Android-only PSS.
• Pass criteria uses performance metrics wording instead of implying a cross-platform memory threshold.

No additional commit was needed in this pass.
