+# Runic Gateway — Android app
+
+A native Android client for a Runic Gateway shard's **public site + player self-service**. It is
+**purely an API client of the website backend** — it never talks to the `link/` sidecar or the game
+shard directly, and it ships none of the shard/sidecar wiring. It surfaces the same content and
+player features as the website's browser client, **minus every administrative/management console**.
+
+The authoritative design contract is [`docs/android/PLAN.md`](https://gitea.whitlocktech.com/RunicGateway/docs)
+in the `RunicGateway/docs` repo. The authoritative API reference is the committed OpenAPI spec at
+`website/server/swagger/swagger-output.json`.
+
+## Status
+
+**M0 — repo scaffold.** Gradle + Compose + Hilt skeleton with CI (lint + unit test + debug build).
+The functional Kotlin pass (M1–M4) and the design pass (M5) follow — see the plan's milestones (§9).
+
+## Stack
+
+| Concern | Choice |
+|---|---|
+| Language / UI | Kotlin + Jetpack Compose (Material 3) |
+| Navigation | Navigation-Compose, single-activity |
+| HTTP | Retrofit + OkHttp, `kotlinx.serialization` |
+| Async | Coroutines + Flow |
+| DI | Hilt |
+| Prefs / base URL | Jetpack DataStore |
+| Tokens at rest | EncryptedSharedPreferences |
+| Images | Coil |
+| Min SDK | Android 10 (API 29) |
+| Target / compile SDK | 35 |
+
+Dependency and plugin versions are pinned in [`gradle/libs.versions.toml`](gradle/libs.versions.toml).
+
+## Build
+
+Requires **JDK 17** and the Android SDK (`ANDROID_HOME` / `local.properties`).
+
+```bash
+./gradlew assembleDebug     # build a debug APK -> app/build/outputs/apk/debug/
+./gradlew test              # JVM unit tests
+./gradlew lint              # Android lint
+./gradlew installDebug      # install on a connected device/emulator
+```
+
+The app self-configures its server URL on first run (PLAN.md §3), so a single build works against
+any shard's website — there is no compiled-in API host.
+
+## CI
+
+`.gitea/workflows/pr-checks.yml` gates PRs into `main` with `./gradlew lint test assembleDebug` on the
+org's self-hosted runner (JDK 17 + Android SDK). Debug builds are auto-signed, so the gate needs no
+secrets. A signed **release** APK attached to a Gitea release comes at M6.
+
+## Contributing
+
+See [`CONTRIBUTING.md`](CONTRIBUTING.md). **AI-assisted contributions must be disclosed** (org
+policy): tick the PR box naming the tool and add a `Co-Authored-By` trailer to AI-authored commits.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
