Neroland Core

Additive minor — new APIs and content only; no removals. Every existing API signature, tag, id, and capability is unchanged (frozen-between-majors policy, see docs/API-STABILITY.md).

Added

Universal machine side configuration (za.co.neroland.nerolandcore.sideconfig)

• A Mekanism-style, per-face routing system every machine inherits — by extending the base AbstractMachineBlockEntity, or by composing a SideConfigComponent (so a mod with its own machine hierarchy adopts it without re-parenting). See docs/SIDE-CONFIG.md.
• Model: Channel (ITEM/FLUID/GAS/ENERGY), SideMode (DISABLED/INPUT/OUTPUT/IO/PUSH), RelativeFace (relative to facing, resolved each query via FaceResolver), SlotGroup, SidePreset (GENERATOR/PROCESSOR/STORAGE/ALL_INPUT/ALL_DISABLED), and a SideConfig.builder() author API (declare channels, bind slot groups, set a preset, allow(...) to forbid modes).
• Capability gating: Core exposes a (face, channel) capability only when the resolved mode permits it — INPUT insert-only, OUTPUT extract-only, IO full, DISABLED none — wired to the item / NeroFluidStorage / NeroGasStorage / energy seams, with neighbour update + capability invalidation on every change.
• Auto-eject / auto-input: optional per-channel toggles, off by default, bounded by the new server-authoritative sideConfigAutoTransferRate config value.
• Persistence & sync: compact per-channel packed-int NBT (survives unload + dimension travel); server-authoritative SideConfigIntentPayload / SideConfigSyncPayload — clients send intents, never mutate routing directly.
• UI: a reusable SideConfigWidget — flattened cube/net, click-to-cycle, colour-coded modes, per-channel sub-tabs, auto-eject/auto-input toggles, copy/paste, reset-to-preset.
• Configurator API: sideconfig.Configurator (cycle / read / snapshot / apply) for an in-world wrench item shipped by a content mod (Nerotech).
• Privacy: side config is block/world data keyed by position — no player identity, not routed through PlayerDataErasure, never logged at info, no telemetry (POPIA/GDPR).
