  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.). Reference material — load when you need a concrete path or
  a definition rather than narrative explanation.

# AOSP Internals — Appendices

Reference material: a per-chapter index of key source files, and a glossary
of AOSP-specific terms.

## Files in this skill

- `A-appendix-key-files.md` — per-chapter table of the most important AOSP source files (sorted ascending by chapter number)
- `B-appendix-glossary.md` — definitions of AOSP-specific acronyms and terms

## When to load which file

- Need a specific source file path for a subsystem → `A-appendix-key-files.md`
- Need a definition of an AOSP acronym (Treble, VINTF, GKI, APEX, AIDL, HIDL, etc.) → `B-appendix-glossary.md`
