Core value: Archive impossible to unpack without knowing the format -- standard tools (7z, tar, unzip, binwalk) cannot recognize or extract contents Current focus: Milestone v1.1 Directory Support -- Phase 9: Kotlin Decoder Update COMPLETE

Current Position

Phase: 9 of 11 (Kotlin Decoder Update) -- COMPLETE Plan: 1 of 1 -- COMPLETE Status: Phase 9 complete, Kotlin decoder updated for v1.1 format with directory support Last activity: 2026-02-26 -- Phase 9 Plan 01 executed (Kotlin decoder v1.1 update)

Progress: [#############.......] 68% (13/~19 plans estimated)

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)
  • v1.1: DFS preorder with sorted children for deterministic parent-before-child ordering
  • v1.1: Extracted crypto pipeline into process_file() helper for reuse
  • v1.1: Directory entries skip data_offset computation (offset=0, no ciphertext)
  • v1.1: Permissions stored as lower 12 bits of mode_t (0o7777 mask)
  • v1.1: Kotlin decoder uses Java File API owner/everyone permission model (no group-level granularity)
  • v1.1: Directory entries in Kotlin decoder skip crypto pipeline entirely, use mkdirs()
  • v1.1: Permission application order: everyone flags first, then owner-only overrides

Pending Todos

None yet.
