Document type: Configuration / Decision Impact Assessment
Version: 0.9.2
Status: Baseline Candidate
Language: English
Product: Chanora
Repo path: docs/governance/decision-impact-assessment.md ---

1. Purpose

This document records how key unresolved product and architecture decisions affect requirements, architecture, detailed design, verification, release readiness, security, privacy, and legal work products.

2. High-Impact Decision Assessment

Decision Recommended decision Impact if changed later
Minimum iOS version iOS 13 Test matrix, platform support policy, app store build configuration, platform behavior tests.
Minimum Android version API 24 Device support, permissions, audio routing, Google Play compatibility, platform tests.
Android target SDK Google Play-required API level on upload date; current release gate uses API 35+ unless newer policy applies
Apple App Store SDK gate Xcode 26+ with iOS 26 / iPadOS 26 SDK+ for App Store Connect upload on or after 2026-04-28 unless newer Apple upload policy applies Google Play submission eligibility and platform permission behavior.
Multiple active connections Exclude from MVP If added later, affects state model, audio routing, UI layout, reconnection logic, storage, verification.
AEC/AGC/NS/HPF defaults Enabled by default where supported Affects UX, CPU, platform-specific audio settings, verification matrix.
Audio processing path Platform-native first; fallback later Affects audio architecture, Rust/native dependencies, latency, CPU, platform compatibility.
Trademark/legal review Required before public/store release Blocks public release if unresolved.
Local DB SQLite or equivalent Affects storage schema, migrations, backup/delete policy, tests.
Bridge Stable typed generated/schema-controlled bridge Affects API stability, async event flow, maintainability, code generation, tests.
Diagnostics upload No automatic upload in MVP Affects privacy policy, security review, support process.
Crash reporting Disabled unless later approved Affects privacy/legal docs, dependency and supply-chain review.
