Port OreSpawn 4.0.16 to Forge 1.10.2

[SkyBlade1978]

Summary

Ports the accepted OreSpawn 4.0.16 campaign to Minecraft 1.10.2 / Forge 12.18.3.2511 as 4.0.16.110021.

Changes

• protects air, liquids, bedrock and block-entity positions even when provider configuration declares them as terrain hosts;
• evaluates Stable Layers rock ranges against actual world Y while preserving shifted formation identity;
• adds immutable ore-dimension biome ID and dictionary include/exclude builder/getter contracts through the existing schema fields;
• accepts canonical namespaced and legacy unnamespaced geome IDs in the editors;
• converts exposed snow layers at top + 1 while preserving buried/authored Snow and Ice;
• carries the ForgeGradle 7 reproducible-release, documentation, Eclipse, cold-bootstrap and CI/CD platform forward for this target;
• uses Forge 1.10's required bare nogui server argument in generated and hosted launches.

Forge 1.10's biome registry and lookup are static/two-dimensional, so the 4.0.11 dynamic-registry, 4.0.12 sampler-height and 4.0.15 3D-attribution repairs are target-inapplicable. Forge 12 has no server GameTest harness, so 4.0.16 retains ordinary benchmark auto-stop without introducing a compatibility hook. The later 4.0.17 Cleanroom Codec repair is intentionally not included; the confirmed collision is specific to the Forge 1.12.2/Cleanroom environment.

Compatibility

Preserves API major 1, schemas 4/6/5, registry IDs, provider meanings, profile filenames, Mineralogy/OS1/OS3 migration behaviour, existing chunks and [4.0.6,5.0.0) compatibility. The changelog and all release identities are updated through 4.0.16.110021.

Validation

• 155 tests across 39 suites, zero failures/errors/skips;
• 19 structured resources parsed, 16 mixed-case locales with 357 matching keys, and byte-identical 21-document exports;
• complete offline build/Javadoc/artifact/checksum and ForgeGradle 7 Eclipse gates;
• cold exact-commit lifecycle plus empty-cache Forge bootstrap and offline same-cache replay;
• userdev and exact reobfuscated packaged server fresh/reload qualification using bare nogui;
• packaged client world creation, all eight long editor fields, rendering, save/reopen and clean exit;
• migration, preferred-seed, natural-host, Stable Layers, weather, fluid and staged performance qualification;
• Java 8 bytecode, Forge 12 metadata, SRG reobfuscation, both packaged access transformers, and zero fixture/test/world/tool leakage;
• exact candidate a4c8c93a5e2f114ef0bdb586ff1e0d21a16de1de manually accepted before publication.
