**Core value:** Archive impossible to unpack without knowing the format -- standard tools (7z, tar, unzip, binwalk) cannot recognize or extract contents

## Current Position
Phase: 3 of 6 (Round-Trip Verification) -- COMPLETE
Plan: 2 of 2 in current phase (all done)
Status: Phase 3 complete, ready for Phase 4
Last activity: 2026-02-24 -- Golden vectors + round-trip integration tests (32 total tests passing)
Phase: 4 of 6 (Kotlin Decoder) -- COMPLETE
Plan: 1 of 1 in current phase (all done)
Status: Phase 4 complete, ready for Phase 5
Last activity: 2026-02-25 -- Kotlin archive decoder with full decode pipeline and cross-validation test script

- Phase 3: Corrected HMAC golden vector (openssl pipe+xxd produced wrong value; verified with file input and Python)
- Phase 3: cargo_bin! macro for non-deprecated assert_cmd binary resolution
- Phase 3: 11MB deterministic pseudo-random data for large file test (wrapping_mul Knuth hash)
- Phase 4: Single-file Kotlin decoder (ArchiveDecoder.kt) for simplicity and Android embeddability
- Phase 4: RandomAccessFile for seeking to data blocks instead of reading entire archive into memory
- Phase 4: HMAC failure skips file, SHA-256 mismatch warns but writes (matching Rust behavior)
- Phase 4: Kotlin signed byte handling with .toByte() for literals > 0x7F, contentEquals() for ByteArray comparison
