# Project State
|
|
|
|
## Project Reference
|
|
|
|
See: .planning/PROJECT.md (updated 2026-02-24)
|
|
|
|
**Core value:** Archive impossible to unpack without knowing the format -- standard tools (7z, tar, unzip, binwalk) cannot recognize or extract contents
|
|
**Current focus:** Phase 1: Format Specification
|
|
|
|
## Current Position
|
|
|
|
Phase: 1 of 6 (Format Specification) -- COMPLETE
|
|
Plan: 1 of 1 in current phase
|
|
Status: Phase 1 complete, ready for Phase 2
|
|
Last activity: 2026-02-24 -- Format specification written
|
|
|
|
Progress: [█░░░░░░░░░] 12%
|

|
## Performance Metrics
|
|
|
|
**Velocity:**
|
|
- Total plans completed: 1
|
|
- Average duration: 7 min
|
|
- Total execution time: 0.1 hours
|
|
|
|
**By Phase:**
|
|
|
|
| Phase | Plans | Total | Avg/Plan |
|
|
|-------|-------|-------|----------|
|
|
| 1. Format Specification | 1 | 7 min | 7 min |
|
|
|
|
**Recent Trend:**
|
|
- Last 5 plans: 7min
|
|
- Trend: baseline
|
|
|
|
*Updated after each plan completion*

## Accumulated Context
|
|
|
|
### Decisions
|
|
|
|
Decisions are logged in PROJECT.md Key Decisions table.
|
|
Recent decisions affecting current work:
|
|
|
|
- Roadmap: Format spec must precede all implementation (all three decoders build against same spec)
|
|
- Roadmap: Obfuscation (XOR headers, encrypted TOC, decoy padding) deferred to Phase 6 after all decoders work without it
|
|
- Phase 1: IV stored only in TOC, not duplicated in data blocks (simplifies shell dd extraction)
|
|
- Phase 1: Same 32-byte key for AES-256-CBC and HMAC-SHA-256 in v1 (v2 will use HKDF)
|
|
- Phase 1: Magic bytes 0x00 0xEA 0x72 0x63 (leading null signals binary)
|
|
- Phase 1: HMAC scope = IV (16 bytes) || ciphertext (encrypted_size bytes)
|
|
|
|
### Pending Todos
|
|
|
|
None yet.
|
|
|
|
### Blockers/Concerns
|
|
|
|
- Open question: Does target busybox have `openssl enc -aes-256-cbc` with `-K`/`-iv` flags? (affects Phase 5)
|
|
- Open question: Is `xxd` available in target busybox? Fallback: `od` (affects Phase 5; spec includes od fallback functions)
|
|
- RESOLVED: HMAC uses same key as AES in v1 (decided in Phase 1 spec, v2 will use HKDF)
|
