# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-25)

## Current Position

Plan: Not yet planned
Status: Ready to plan
Last activity: 2026-02-25 -- v1.1 roadmap created (phases 7-11)

Progress: [##########..........] 55% (10/~18 plans estimated)

## Performance Metrics

**Velocity (from v1.0):**
- Total plans completed: 10
- Average duration: 3.6 min
- Total execution time: 0.6 hours

## 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)

### Pending Todos

None yet.

### Blockers/Concerns
