Summary

Bring baseSteam 2.2.16.121111 to Minecraft 1.21.11 / Forge 61.1.0 with Java 21.

Keep the existing IDs, saved machine fields, recipes, configuration and machine balance. Base Metals is required on both client and server. The build now pins the verified public basePower 2.4.15.121111 and Base Metals 3.1.2.121111 releases, with OreSpawn 4.1.0.121111 unchanged.

The portable atlas test uses the configured, checksum-verified Power jar. Native resource-test subprocesses disable interactive terminal setup without filtering warnings or errors.

Verification

• Full default-path release suite: 45 tasks, 252 tests, no failures, errors or skips.
• Real Eclipse ECJ: main, unit and GameTest scopes compile; all 252 ECJ-compiled tests pass without ignored tests or assumptions.
• All four named native Steam GameTests pass.
• Fresh packaged Steam operations, complete server restart and both stopped raw-save audits pass on the final public-pin family profile.
• Independent offline path-with-spaces source build: all 20 tasks and 252 tests pass, and all three release jars reproduce exactly. Its source-only Git index matches the exact source tree; the initial missing-Git-metadata attempt remains preserved separately.
• Public dependency downloads and source ancestry pass the same verification script used by hosted CI.
• Hosted CI and CodeQL pass. Its player and sources match the local hashes exactly. The hosted Javadoc hash is EABB8659A546702C693A4BAEA3D9AB9A126954EC4BD5ADA8235740F9D8906CA6; the five differing JDK asset/license entries are proven platform differences, not changed Steam documentation.

The actual releaseJar output is byte-identical to the accepted Steam jar: F23DDC4ABB36A1C4C7A4205151FBB6DDFD25397E86909E1C0B146C4089B747E0. All 324 payload entries, including 69 classes and the manifest, match.

Manual release acceptance is recorded. Live publication remains held until the fresh final-hash family endurance and independent replay gate passes. This PR does not publish or begin the 26.1.2 port.
