Update the Minecraft 1.10.2 add-on to 0.1.3.110021, using released Building Pieces 0.3.7.110021. Players can stack matching BOP corners into steps and steps into slabs using the core's recombination recipes. The 33 materials, 66 palettes, registry IDs and saved slots are unchanged.

Pin dependency builds to the core's exact released source commit and update the required version and player guides. CurseForge publication is limited to one attempt; an uncertain response must be checked against the file list and hash before any retry. The workflow retains the CurseForge file-ID receipt and required core/BOP dependencies.

Validation:

• 15 unit tests, development fresh/reload runtime checks, build, Javadocs, Eclipse isolation and artifact audits passed.
• Exact packaged client fresh/reload and standalone/combined server fresh/reload gates passed. Combined checks use released Grass Slabs, Mineralogy and OreSpawn jars with verified hashes.
• Runtime checks cover 1,138 supported BOP states, all 16 historical step codes, native material properties and 21,280 recombination cases (25,792 with Mineralogy).
• A disposable save made with released core 0.3.6 and add-on 0.1.2 retained 968 custom BOP piece states, 180 stacks containing 2,805 item units, dropped-stack NBT and populated migration history through upgrade/reload. Source fixture hash was unchanged.
• Two builds produced identical main, sources, Javadocs and checksums. Java 8 bytecode and all 18 languages are checked; no core classes, native mod assets, probes, local paths or agent files are included.
• Pinned publisher retry checks verify one request for success, HTTP 500 and timeout. The former two-attempt control reproduces the duplicate request.
