[1.18.2] Creation editor rejects namespaced geome IDs in valid templates #269

Environment

• Minecraft: 1.18.2
• Forge: 40.3.0
• OreSpawn: local candidate 4.0.12.118021
• Candidate commit: 7c82ecc844ae9d241a108f4417c6c3b5b0bc29a2
• Candidate JAR SHA-256: 0478D611A96020DAAE794B72E64EFD677B49A5B63BCB6179330D63317B16D6A6
• Integration mod: CakeWorld master-1.18.2, provider revision 58
• Fixed acceptance seed reserved for the post-editor world: 5059928472718672684

Summary

The creation-time editor rejects a valid provider template when its geome keys are namespaced resource IDs. CakeWorld's template is auto-selected and the editor can display its installed biome/material configuration, but pressing Done fails with:

Invalid geome: cakeworld:cocoa_basin

The world therefore cannot be created from the editor selection, so the saved snapshot and generated-world phases of acceptance are unreachable.

Reproduction

1. Launch a Forge 1.18.2 client with OreSpawn 4.0.12.118021 and CakeWorld installed.
2. Choose Singleplayer and begin creating a new world.
3. Open the OreSpawn... editor.
4. Observe that Template: Cake World is already auto-selected.
5. Press Done without editing the template.

Actual

The editor remains open and shows red validation text:

Invalid geome: cakeworld:cocoa_basin

Expected

The editor accepts namespaced geome IDs that are valid in the packaged provider/runtime contract, returns to world creation, and saves the selected profile into serverconfig/orespawn-worldgen.json when the world is created.

Technical diagnosis

GeologyEditorSession validates geome keys in both addGeome and final validate() with the unnamespaced-only expression:

[a-z0-9_.-]+

See the current candidate around GeologyEditorSession.java:633 and :693. A key such as cakeworld:cocoa_basin is valid provider/runtime data but necessarily fails this editor-only expression because of :.

This is not a provider runtime failure. The same exact 4.0.12 candidate successfully bakes CakeWorld revision 58 with 14 geomes in all three dimensions, and the headless fresh/reload integrated generation tests consume those namespaced geomes.

Suggested correction and regression coverage

• Validate geome keys using the same namespaced-ID contract used by the provider parser, or explicitly accept a ResourceLocation-compatible namespace:path value while retaining any intended support for legacy unnamespaced IDs.
• Add a GeologyEditorSessionTest that loads a profile containing cakeworld:cocoa_basin, asserts validate() succeeds, and confirms save/round-trip preserves the key and every reference to it.
• Cover both final validation and adding a new namespaced geome so the two code paths cannot diverge.

CakeWorld OS-020 remains blocked until editor apply, saved world snapshot, and fixed-seed generation all pass against the same unmodified OreSpawn artifact.
