# Rel Platform Release Policy

**Document type:** Release / Platform Release Policy  
**Version:** 0.9.2  
**Status:** Baseline Candidate  
**Language:** English  
**Product:** Chanora  
**Repo path:** `docs/release/platform-release-policy.md`  ---

## 1. Purpose

This document separates runtime deployment targets from app-store upload build-SDK gates.

## 2. iOS / iPadOS Policy

| Policy item | Decision |
|---|---|
| Runtime deployment target | iOS 13 or later unless Flutter, plugin, audio, or product constraints require raising it. |
| App Store Connect upload build-SDK gate | For upload on or after 2026-04-28, use Xcode 26 or later and the iOS 26 / iPadOS 26 SDK or later, unless Apple publishes a newer applicable requirement before upload. |
| Internal Alpha / local development | May use development toolchains suitable for internal testing if no App Store Connect upload is performed. |
| TestFlight / App Store upload | Must satisfy the active Apple App Store Connect upload requirement. |

## 3. Android Policy

| Policy item | Decision |
|---|---|
| Runtime minimum | Android API 24 or later unless Flutter, plugin, audio, or product constraints require raising it. |
| Store upload target API | Target the Google Play-required API level on the upload date. |
| Internal Alpha / sideload testing | May use internal build configuration suitable for internal testing, but release readiness must state whether Google Play rules apply. |

## 4. Release Readiness Rule

The Go/No-Go record shall record:

- runtime minimum versions;
- store upload build/toolchain gates;
- build number;
- commit SHA;
- tag;
- artifact hashes;
- platform-specific release status;
- whether the release is internal-only or store-uploaded.

## 5. Traceability

| Policy | Traceability |
|---|---|
| iOS runtime minimum | SysRS-286 -> SysDes-133 -> SRS-185 -> SAD-061 -> SDD-071 |
| Apple App Store Connect upload SDK gate | SysRS-287 -> SysDes-134 -> SRS-186 -> SAD-062 -> SDD-072 |
| Android runtime and target API policy | SysRS-288/289 -> SysDes-135 -> SRS-187/188 -> SAD-063 -> SDD-073 |
