- Test 6: nested directory extraction (3+ levels deep, 4 files)
- Test 7: empty directory creation without decryption errors
- Test 8: mixed standalone files + directory pack/unpack
- All 5 original test cases preserved unchanged

- Add entryType and permissions fields to TocEntry data class
- Parse entry_type (1 byte) and permissions (2 bytes LE) in parseTocEntry
- Update version check from 1 to 2 for v1.1 format
- Handle directory entries: create dirs without decryption
- Create parent directories for files with relative paths
- Add applyPermissions() using Java File API (owner vs everyone)
- Update entry size formula comment to 104 + name_length

- test_roundtrip_directory: full directory tree with permissions verification
- test_roundtrip_mixed_files_and_dirs: mixed file + directory pack/unpack
- test_inspect_shows_directory_info: inspect output contains dir/file types and permissions

- Bump VERSION constant from 1 to 2
- Add entry_type (u8) and permissions (u16) fields to TocEntry struct
- Update write_toc_entry/read_toc_entry for new field order after name
- Update entry_size formula from 101 to 104 + name_length
- Update all unit tests for v1.1 layout (new fields, version 2, sizes)
- Add placeholder entry_type/permissions to archive.rs ProcessedFile for compilation

- Add XOR_KEY_HEX constant and hex_to_bin() helper (xxd + od fallback)
- Replace magic check with XOR bootstrapping: read 40 bytes, XOR if mismatch
- Write de-XORed header to temp file for field parsing
- Add TOC decryption via openssl enc when flags bit 1 is set
- Switch TOC parsing loop from $ARCHIVE to $TOC_FILE variable
- Update HMAC verification to construct IV from parsed hex (not archive position)
- All 7 cross-validation tests pass (Rust pack -> Shell decode -> SHA-256 match)
- Add XOR_KEY constant matching FORMAT.md Section 9.1
- Add xorHeader() function with signed byte masking (and 0xFF)
- Update decode() with XOR bootstrapping: check magic, XOR if mismatch
- Update decode() with TOC decryption: decrypt when flags bit 1 is set
- Backward compatible: plain headers and unencrypted TOC still work
- pack(): generate decoy padding (64-4096 random bytes per file)
- pack(): encrypt serialized TOC with AES-256-CBC using random toc_iv
- pack(): XOR header buffer before writing (8-byte cyclic key)
- pack(): set flags bits 1-3 (0x0E) for all obfuscation features
- unpack(): XOR bootstrapping via read_header_auto()
- unpack(): decrypt TOC when flags bit 1 is set
- inspect(): full de-obfuscation via shared read_archive_metadata()
- Factor out read_archive_metadata() helper for unpack/inspect reuse
- All existing tests pass (unit, golden, round-trip integration)

- 6 test cases: single text, multiple files, no-compress, empty, large file, Cyrillic filename
- Uses Rust archiver to create archives, sh decode.sh to extract, SHA-256 to verify
- Follows same pattern as kotlin/test_decoder.sh

- Checks prerequisites (kotlinc, java, cargo) with install instructions
- Test 1: single text file round-trip (Rust pack -> Kotlin decode)
- Test 2: multiple files with mixed content (text + 10KB binary)
- Test 3: no-compress mode for pre-compressed files
- Test 4: empty file edge case
- Test 5: large file (100 KB random data)
- SHA-256 comparison of original vs extracted for each test
- Colored output, temp directory cleanup via trap, non-zero exit on failure

- 7 deterministic tests: AES-256-CBC encrypt/decrypt, empty, HMAC-SHA256, HMAC verify, SHA-256 x2
- Fixed IV vectors for reproducible results (no randomness)
- HMAC golden value cross-verified with openssl (file input) and Python hmac module
- SHA-256 values match FORMAT.md Section 12.3 known vectors
