 task without changing upstream's test configuration.
 
+## Optimized side-by-side comparison
+
+The `optimized` build type inherits `release`: R8 optimization/minification,
+resource shrinking, non-debuggable code, dependency consumer keep rules and
+dependency baseline profiles. It changes only signing (the Android debug key),
+package (`org.justinvisser.wolfskin.tv.opt`), launcher label (`Wolfskin (Opt)`)
+and version-name suffix (`-opt`). The launcher icon/banner are unchanged.
+`make apk` remains the clean, release-key-signed production build; neither its
+signing flow nor the existing debug build changes.
+
+Build all four default-flavor outputs in one invocation through the container
+wrapper, without a release keystore. On a host whose Gradle cache already holds
+the pinned native extensions and their metadata:
+
+```sh
+bash docker/gradle.sh optimized --offline \
+  -PWholphinExtensionsUsername=JustinZeus \
+  -PWholphinExtensionsPassword=unused \
+  :app:assembleDefaultOptimized
+```
+
+The unused password is not a credential: offline resolution never contacts
+GitHub Packages. A cold cache instead needs a read-packages credential supplied
+through the existing `ORG_GRADLE_PROJECT_WholphinExtensionsUsername` and
+`ORG_GRADLE_PROJECT_WholphinExtensionsPassword` hooks inside the build container,
+or securely seeded cached artifacts. No release signing inputs are needed.
+Without native extension configuration, the existing dependency selection uses
+the MPV stub and omits ffmpeg/AV1, just like `make apk-debug`; that is not a
+playback-complete comparison. Inspect native libraries before installing.
+
+Outputs are in `app/build/outputs/apk/default/optimized/`: universal, arm64-v8a,
+armeabi-v7a and x86_64. Keep
+`app/build/outputs/mapping/defaultOptimized/mapping.txt` with those APKs to
+deobfuscate crashes. This variant shares release library variants and the release
+`debugHomeSnapshot` implementation, not `src/debug` or its preview JSON/artwork.
+`BuildConfig.DEBUG` remains false: no preview-fixture setting, debug StrictMode
+or Compose diagnostic stack traces.
+
+This is a fresh app sandbox: sign in with Jellyfin Quick Connect or the normal
+server/user flow again; it does not inherit the debug/release app's logins or
+preferences. **Wolfskin screens** defaults on, and the same Advanced switch can
+restore upstream screens. The same Conductarr door
+(`https://wolfskin-tv.justinvisser.org`) and URL override apply. The selected
+Jellyfin user's token is borrowed for Conductarr; no app-specific TV credential
+or embedded secret is added. All other settings retain release behavior,
+including update checks; a production release APK is not an update for this
+separate package/debug signer.
+
+`androidx.profileinstaller` and library-provided profiles already exist. There
+is no recorded app baseline-profile source or Macrobenchmark module.
+`src/optimized/baseline-prof.txt` adds a hand-maintained seed: application and
+activity classes plus their `onCreate` methods, `WolfskinAppKt`,
+`WolfskinScreenPreference` and `ConductarrPreference`. AGP merges it with library
+profiles, rewrites it through R8 and packages `assets/dexopt/baseline.prof` and
+`baseline.profm`. It is not a measured navigation profile or evidence of a speedup.
+To replace the seed, add an AndroidX Baseline Profile producer/Macrobenchmark
+module, record cold launch, Quick Connect/sign-in, person selection, Home,
+Libraries, Discover, title pages and playback on a suitable device, then rebuild
+and compare startup/frame timings. Device-driven recording and runtime checks
+remain separate from an APK build.
+
+Static verification: use `aapt2 dump badging` for package/label/SDKs and absence
+of `application-debuggable`; `apksigner verify --print-certs` for the debug
+signer; `unzip -l` for both dexopt assets, native ABI contents and absence of
+`assets/wolfskin-*`/`assets/library/` fixtures. Review R8 warnings and effective
+consumer rules rather than adding blanket keeps. JVM tests do not prove
+minified Hilt/Room/serialization/JNI runtime safety; exercise sign-in, real
+Conductarr reads, artwork, database reopen and each player on the comparison box.
