## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- v1.0: IV stored only in TOC, not duplicated in data blocks
- v1.0: Manual binary serialization with to_le_bytes/from_le_bytes (no serde/bincode)
- v1.0: Filename-only entry names -- v1.1 changes this to relative paths with `/` separator
- v1.0: Always enable all 3 obfuscation features (no flags)
- v1.0: Two-pass TOC serialization for correct data_offsets with encrypted TOC size
- v1.1: No backward compatibility with v1.0 archives (format version bump)
- v1.1: Only mode bits (no uid/gid, no timestamps, no symlinks)
- v1.1: entry_type and permissions fields placed AFTER name, BEFORE original_size in TOC entry
- v1.1: Directory entries use zero-filled crypto fields (uniform entry structure)
- v1.1: Entry size formula: 104 + name_length (was 101)
