FTB Pregen Map Bridge

## 1.0.0-beta.2 — 2026-11-02

- Read the current chunk location when region-file records move during saving.
- Validate two record snapshots before decoding, with bounded background retries for changing data.
- Handle newly created empty regions and recheck the region fingerprint before saving completion.
- Preserve queue limits, draw budgets, pause/disconnect handling and stable-corruption reporting.

Native tests passed for region relocation, incomplete writes, persistent corruption, terrain palettes/heights/biomes, real FTB drawing and map save/reload. This is not an FPS benchmark or a complete multiplayer validation.

# 1.0.0-beta.1 — previous version

- Adds progressive filling of missing FTB Chunks map tiles from saved local full chunks.
- Adds an LSS 0.20.0 terrain-column consumer for remote clients.
- Uses one background reader/decoder, bounded queues, a configurable chunk-rate cap and sliced native FTB drawing.
- Provides `/ftbmapfill`, `/ftbmapfill pause` and `/ftbmapfill resume`.
- Preserves complete tiles, stops work on disconnect/world change and records completed local regions after native saves are scheduled.
- Supports gzip, zlib, raw Anvil and external chunk records; rejects incomplete or invalid records without writing world files.
- Passed isolated native read/palette/height/biome/LSS-snapshot tests, real FTB map draw/save/reload checks, queue limits, pause and disconnect checks.

First separate-project submission of the existing beta.1 JAR. The staged runtime is byte-identical to the verified installed build. No gameplay code or dependency version was changed for publication. Real-world performance and full multiplayer behavior are not yet verified.
