World and Save Compatibility

[+] Added versioned persistence for machines, cables, tanks, backpacks, Research Journals, Energy Banks, the Chemical Sample Archive, and the complete storage network.

[+] Older unversioned data is migrated safely, while invalid energy, progress, connection-mode, and network-identifier values are bounded or rejected.

[+] Frozen the identifiers required by existing worlds, including 60 blocks, 489 items, block entity types, menus, data components, player attachments, creative tabs, and recipe data.

Server and Networking

[~] Hardened inventory, backpack, filter, machine, Chemical Sample Archive, and storage-network actions. Payloads with invalid context, indices, or sizes are rejected by the server.

[~] Added request-rate limits for GUI actions and protected storage-index synchronization against missing chunks, invalid counts, and oversized data.

[~] Separated client code from shared and server code, including the Research Journal opening flow, so dedicated servers do not load graphical classes.

[+] The recipe catalog synchronized between servers and clients now uses a versioned format, an 8 MiB limit, and validation of headers, counts, trailing data, and all four catalog types.

Chemistry Data and Datapacks

[~] Reloading 606 profiles, 226 reactions, 10 tool assembly recipes, and 8 Alloy Furnace recipes is now a single transaction. A failure in any catalog preserves the last complete valid data set.

[+] Resource validation now checks models, textures, English and Polish names, recipes, tags, chemical profiles, block loot, and the advancement tree with its requirements and cycles.

[+] Automated contracts protect persistence schemas and data identifiers from accidental removal or renaming in future updates.
