EdisonJwa 5aa51c310f docs(p0): SysRS/SysDes/SRS/SAD/SDD/Verification + traceability for Android P0 reconciliation

Full P0 Android documentation chain:

- SysRS: API 24 → API 28 reconciliation per DEC-004 (SysRS-288);
  add SysRS-305 (Android in-call audio mode), SysRS-306
  (RECORD_AUDIO runtime timing).
- SysDes: SysDes-152 (in-call audio mode subsystem), SysDes-153
  (RECORD_AUDIO permission flow), SysDes-154 (Android voice audio
  backend), SysDes-155 (macOS runtime baseline).
- SRS: SRS-187 → API 28; add SRS-208 (in-call audio mode), SRS-209
  (RECORD_AUDIO + listen-only fallback), SRS-210..215 (Android voice
  audio backend latency/preset/AEC/usage/sharing/foreground service);
  retarget SysDes anchors from generic SysDes-135 to SysDes-152/153/154.
- SAD: SAD-063 refreshed (API 28); add SAD-084 (audio mode
  controller), SAD-085 (permission adapter with listen-only),
  SAD-086 (foreground service), SAD-087 (macOS runtime baseline);
  formalize cross-cutting + platform-specific allocation pattern
  in §24.1.
- SDD: expand SDD-028 (BackIntentService); refresh SDD-073 (build
  config); add SDD-105 (JNI bootstrap), SDD-106 (permission
  requester), SDD-107 (foreground service), SDD-108 (audio mode
  controller), SDD-109 (AAB pipeline), SDD-110 (PTT capability),
  SDD-111..116 (Android voice audio backend), SDD-118 (Android
  bridge build automation), SDD-119 (iOS/macOS bridge build
  automation back-fill).
- Verification: create android-p0-acceptance.md TC-1..TC-18; add
  SWE4-UV-040..052, SWE5-IV-016..026, SWE6-SV-018..030,
  SYS4-SIV-015 strengthened + SYS4-SIV-017/018.
- Governance: traceability matrix v0.9.9 with end-to-end chain
  closure; DEC-032 documents the temporary abiFilters reduction to
  arm64-v8a only and its restore-by gate.

Trace: full chain SysRS → SysDes → SRS → SAD → SDD → Code → Verification.

CHANORA_CFG_Decision_Impact_Assessment_v0.9.2.2.1

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 28 (per DEC-004, Accepted 2026-05-14; raised from the original API 24 recommendation)	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.

3. Document Update Rules

If decision changes	Update required
Minimum iOS/Android version changes	SysRS, SysDes, SRS, SAD, SDD, SYS.4, SWE.6, Release Readiness
Apple SDK submission gate changes	SysRS, SysDes, SRS, SAD, SDD, SWE.6, Release Readiness
Android target SDK changes	SRS, SWE.6, Release Readiness, Platform Guide
Multiple connections added to MVP	SysRS, SysDes, SRS, SAD, SDD, SWE.4, SWE.5, SWE.6, SYS.4
Audio defaults change	SysRS, SysDes, SRS, SAD, SDD, SWE.4, SWE.5, SWE.6
Audio implementation path changes	SysDes, SAD, SDD, SWE.4, SWE.5, SYS.4
Legal/trademark policy changes	Release Readiness, Legal Review, Privacy Policy, External References
DB choice changes	SysDes, SRS, SAD, SDD, SWE.4, SWE.5
Bridge choice changes	SysDes, SAD, SDD, SWE.4, SWE.5
Diagnostics upload enabled	SysRS, SysDes, SRS, SAD, SDD, Threat Model, Privacy Policy, Redaction Audit, Release Readiness
Crash reporting enabled	SysRS, SysDes, SRS, SAD, SDD, Privacy Policy, Dependency Report, Release Readiness

4. Recommended Decision Closure Sequence

Confirm mobile minimum versions and Android target SDK policy.
Confirm one active server connection for MVP.
Confirm audio processing defaults.
Confirm audio implementation path.
Confirm diagnostics/crash reporting privacy policy.
Confirm SQLite/equivalent local database.
Confirm bridge choice.
Confirm legal/trademark/public wording review requirement.
Confirm license model before public release.
