AOSP Internals — Appendices. Use when looking up a key file path
(per-chapter table of the most important AOSP source files: build, init,
kernel, HAL, framework services, system apps, infrastructure) or the
meaning of an AOSP-specific acronym/term (Treble, VINTF, GKI, APEX, AIDL,
HIDL, etc.), why Kotlin is absent from the public API, or what changed from
Android 16 to Android 17. Reference material — load when you need a concrete
path, a definition, or a changelog rather than narrative explanation.

Reference material: a per-chapter index of key source files, a glossary of
AOSP-specific terms, a note on the Kotlin/public-API asymmetry, and the
Android 16→17 changelog.
