<segfault>
Let's go through it one by one:
test__GOLEM:Unrecognized Creature Caste Body Token: ENERGY_CRYSTAL
test__GOLEM:Unrecognized Creature Caste Body Token: ENCASED_SOUL
You can't just write any bodyparts into the [BODY:] tag, you can only use those defined in body_default.txt and body_rcp.txt (although you can make your own bodyparts if you like).
test__GOLEM:Body detail plan not found:CLAY
As before, there is no CLAY body detail plan, you can only use those defined in b_detail_plan_default.txt (or just define your own).
Unrecognized Body Part Group Token: BY_CATAGORY
Simple spelling error. Note that you also misspelled ENGERGY_CRYSTAL on the same line.

These body part modifiers can't be used if there are no relevant bodyparts to apply them to.
test__GOLEM:Attack BITE seems to have correct format but could not find proper BPs in any caste, so not added
The attack is looking for tooth bodyparts attached to head bodyparts. Your golem doesn't have any such teeth.
test__GOLEM:Unrecognized Creature Token: HOMEOTERM
test__GOLEM:Unrecognized Creature Token: MULTIPLE_LITTER_COMMON
Also spelling errors.
<lots of material and tissue errors>
You can't simply expect a material or tissue to exist when you name it. You did well with the DEVILED_ENERGY, defining it from a template before it got used, and you almost got the CLAY right, but the [BODY_DETAIL_PLAN:VERTEBRATE_TISSUE_LAYERS:::::] expects tissue names, not material names, and your golem doesn't have any CLAY, PURE_ENERGY and PALE_ENERGY tissues that it could use.
