BestAutoSort

Standalone storage mod for Valheim (GUID dev.maks2204.bestautosort). Updated and tested for Valheim 1.0.12.

• Shared chests: every player can open the same chest at the same time, no lockouts
• Quick-stack: hotkey moves matching items into nearby storage
• Lock and restock: Alt + left-click cycles an item through Locked → Replenish → Nothing
• Storage rules: per-chest item/category filters, presets, reserves
• Crafting and building: materials from nearby chests within radius
• Fuel and ingredients: machines, cooking stations, kilns, smelters, fermenters pull from nearby chests
• Animal feeding: hungry tame animals fed automatically from nearby chests
• Chest upgrades: wooden → Reinforced / Black Metal / Grausten tiers, contents kept
• Sort and trash: LeftAlt + S sorts the open chest, Trash button deletes

Notes:

• Own plugin folder (BepInEx/plugins/BestAutoSort/), own config (dev.maks2204.bestautosort.cfg).
• Console command: bestautosort.
• All players + server must run the same version (exact-match hello gate).

0.6.x server authority: the 0.6.x-Dedicated-Test line makes the server/host the permanent owner of eligible chests (option-B ZDO manager: Take / Add / Move / Sort / UpgradeRequest / Destroy served server-side — validate → apply → Save() → revision → respond; upgrades charge target-minus-current with pocket refunds). Live-verified single-peer (Accepted end-to-end, incl. upgrades with marker/dims/look). The multi-peer invariant is not yet claimed (2-player flow, hammer destroy on the run, autofeed soak pending). Mode/hello gate: peers must match on version AND auth mode (version;auth=N); mismatched peers are rejected. Vanilla (mod-less) clients are unsupported for managed chests (view-only grant at best; local vanilla takes fork ghost items). Remote chest upgrade runs only via the server-mediated TxOp.UpgradeRequest contract (legacy direct-upgrade frames refused); see docs/remote-upgrade-mediated.md including its 4 documented residuals.

Multiplayer protocol (ChestTX)

+----------------+
|   ONE CHEST    |
|   ONE OWNER    |  <- ZDO owner = SERVER, permanent, never migrates
|   ONE TX       |  <- validate -> apply -> Save() -> revision -> respond
|   AT A TIME    |     (per-chest serial queue, main thread)
+----------------+

Details: docs/CHEST_TX.md.
