A high-performance C++ cross-platform build CLI
# Tasks: Align Rust ccgo-rs Android Build Output with Python pyccgo

## Feature Overview

Align the Rust ccgo-rs Android build output structure with the Python pyccgo version to ensure compatibility and consistency.

## User Stories

- **US1**: As a developer, I want the Rust Android build to produce the same archive structure as Python so that consumers have a consistent experience.
- **US2**: As a developer, I want stripped release libraries so that the output is production-ready with smaller file sizes.
- **US3**: As a developer, I want symbols archives so that I can debug production crashes.

## Dependencies

```
Phase 1 (Setup) → Phase 2 (Foundational) → US1/US2/US3 (can be parallel) → Phase 5 (Polish)
```

---

## Phase 1: Setup (SKIPPED - Keep Python ccgo as is for now)

- [ ] T001 Rename Python ccgo package to pyccgo in `../ccgo/setup.py`
- [ ] T002 Update Python ccgo CLI entry point to pyccgo in `../ccgo/ccgo/main.py`
- [ ] T003 Update Python package name in pyproject.toml or setup.cfg if exists

---

## Phase 2: Foundational - Android NDK Toolchain Enhancements ✅ COMPLETED

- [x] T004 Add llvm-strip path detection to AndroidNdkToolchain in `src/build/toolchains/android_ndk.rs`
- [x] T005 Add STL library path getter (libc++_shared.so) to AndroidNdkToolchain in `src/build/toolchains/android_ndk.rs`
- [x] T006 Add strip_library() method to AndroidNdkToolchain in `src/build/toolchains/android_ndk.rs`

---

## Phase 3: User Story 1 - Archive Structure Alignment ✅ COMPLETED

**Goal**: Produce identical archive structure to Python version

**Independent Test**: Build Android with both tools, compare ZIP contents

- [x] T007 [US1] Change platform name from "android" to "Android" in `src/build/platforms/android.rs` and `src/commands/build.rs`
- [x] T008 [US1] Update cmake_build_dir to use "Android" via BuildTarget::Display trait in `src/commands/build.rs`
- [x] T009 [P] [US1] Add obj/ directory structure for symbols to symbols staging in `src/build/platforms/android.rs`
- [ ] T010 [P] [US1] Add haars/ directory support to ArchiveBuilder in `src/build/archive.rs` (DEFERRED - AAR support)
- [x] T011 [US1] Update AndroidBuilder to add unstripped libs to symbols staging in `src/build/platforms/android.rs`

---

## Phase 4: User Story 2 - Library Stripping ✅ COMPLETED

**Goal**: Strip debug symbols from release shared libraries

**Independent Test**: Compare file sizes before/after stripping

- [x] T012 [US2] Implement strip_shared_libraries() method in AndroidBuilder in `src/build/platforms/android.rs`
- [x] T013 [US2] Call strip_shared_libraries() for release builds after build_link_type() in `src/build/platforms/android.rs`
- [x] T014 [P] [US2] Add STL library copying (libc++_shared.so) to shared library output in `src/build/platforms/android.rs`

---

## Phase 5: User Story 3 - Symbols Archive ✅ COMPLETED

**Goal**: Create -SYMBOLS.zip with unstripped libraries for crash debugging

**Independent Test**: Build Android, verify -SYMBOLS.zip exists with unstripped .so files

- [x] T015 [US3] Create symbols staging directory structure (obj/{arch}/) in AndroidBuilder in `src/build/platforms/android.rs`
- [x] T016 [US3] Copy unstripped shared libraries to symbols staging before stripping in `src/build/platforms/android.rs`
- [x] T017 [US3] Call archive.create_symbols_archive() after main archive in `src/build/platforms/android.rs`
- [x] T018 [US3] Update BuildResult to return symbols_archive path in `src/build/platforms/android.rs`

---

## Phase 6: Polish & Cross-Cutting Concerns ✅ COMPLETED

- [x] T019 Add verbose logging for strip operations in `src/build/platforms/android.rs`
- [x] T020 Update clean() to handle "Android" directory name in `src/build/platforms/android.rs`
- [ ] T021 [P] Add unit tests for new AndroidNdkToolchain methods in `src/build/toolchains/android_ndk.rs` (DEFERRED)
- [x] T022 [P] Update documentation/comments to reflect new output structure in `src/build/platforms/android.rs`
- [ ] T023 Verify output matches Python version by building test project (MANUAL TEST)

---

## Parallel Execution Opportunities

### Within Phase 2 (Foundational):
- T004, T005, T006 can run in parallel (independent method additions)

### Within Phase 3 (US1):
- T009 and T010 can run in parallel (different archive additions)

### Within Phase 4 (US2):
- T014 can run in parallel with T012/T013 (STL is independent of strip)

### Within Phase 6 (Polish):
- T021 and T022 can run in parallel (tests vs docs)

**Status**: ✅ Core Android alignment completed. Archive structure, library stripping, and symbols archive now match Python pyccgo output.

**Files Modified**:
- `src/build/toolchains/android_ndk.rs` - Added llvm_strip_path(), stl_library_path(), strip_library(), copy_stl_library()
- `src/build/platforms/android.rs` - Added strip_shared_libraries(), symbols archive support, updated platform name to "Android"
- `src/commands/build.rs` - Updated BuildTarget::Android display to "Android"

**Remaining Work (Deferred)**:
- T010: AAR/HAR support (haars/ directory) - requires additional Gradle integration
- T021: Unit tests for AndroidNdkToolchain methods
- T023: Manual verification with test project
