Slabbed — 0.1.2-alpha

Added

• Expanded underside attachment support for top slabs:
  • Chains (including chain-to-chain stacking and chains connecting to lanterns)
  • Hanging signs
  • Hanging roots
  • Spore blossoms
  • Pointed dripstone
  • Trapdoors
  • Bells
  • Lightning rods
  • The vine thingies from the Nether
• Core placement + survival logic now treats the top face of top slabs as valid support for most hanging/underside decor.
• Strict visual alignment maintained for all supported blocks (no floating offsets).

Improved

• Stability of chained underside attachments (neighbor updates + reloads).
• Reduced recursion and update edge cases around underside placement.
• Debug tooling isolated and cleaned up for future investigation.

Fixed

• Resolved ghost block rendering caused by invalid client-side offsets in several cases.
• Prevented client-only geometry for most non-decorative blocks.
• Ongoing fix in progress for carpet-like blocks (snow layers / carpet), which may still ghost in certain slab-over scenarios.

Known Limitations

• Stairs are not supported as underside anchors (explicitly out of scope for now).
• Redstone power does not descend through slabs:
  • Power currently propagates upward only.
  • Powered rails placed on slabs require a same-level activator (lever/torch adjacent on slab height) to activate.
• Carpet and snow layer interactions are still being finalized.
• Chains under top slab do not yet attach to a block underneath.

Notes

• This is an alpha release focused on functional coverage and correctness, not full parity.
• Behavior is intentionally conservative: no global solidity lies, no implicit stair handling, no redstone hacks.
