Whole historical block batch · October 18, 2026

Advent of Ascension is created by Tslat and contributors. The cumulative private 1.20.1 / Forge 47.4.23 playtest restores Ancient Glass, Toxic Stem, adjustable Structure Light and Clear Water with its bucket together. Ancient Vines Cap uses the newer capped-plant owner without a duplicate. Original textures stay; the bucket model changes only two required Forge API field names.

The whole native client/server, all 24,295 unique JAR members, 34 native state codec cases, all 16 light/water states across 25 worlds and native bucket placement/pickup pass. No preceding member is removed. The 14-skill/112-boundary, Anima/Extraction/Foraging, 17 merchant payments and nine saved-offer fixtures remain. Ordinary signed-in rendering/movement and server save/restart pass. Required Hari62 Vulkan and OpenGL each pass 24 actual GUI state cases. Both playtest profiles update in place; vanilla hearts remain default.

All 1,186 blocks, 2,596 items and 632 entity identities from the mature 1.16.5 baseline now resolve through exact current keys or native alias/variant save fixtures. This is identity coverage, not complete behavior, sound equivalence, every 1.7.10 feature or latest modernization. Generated broken controls remain explicitly labeled. The initial instrumentation method error is retained in local evidence; game code was not changed to bypass it.

The complete historical/latest union, natural full progression, arbitrary old user saves, multiplayer, full-pack compatibility, raster parity and sustained 2,000 FPS remain open. The inherited transition warning is still visible; it has not been hidden as a completion shortcut. Original mod code/assets and modified JARs remain local. C: storage reduction is separate and its 20 GB aggregate budget remains unmet.
