Zombie Village 4.57.321 — release notes

Rollup of 4.57.318 through 4.57.321 — the liquid-handling arc: villages now deal with water and lava instead of fighting them.

What's new

• Builders handle water and lava at the build site. Sources next to the work are sealed with cobblestone; a feed the builder can't reach from where it stands starts a full response — the builder walks over and neutralizes or contains the liquid, then gets back to work. Flooded cells inside a house footprint are plugged and cleared.
• Catacomb crews handle underground aquifers: flooded carve cells get budgeted plug/seal responses, and a flood is traced upstream so the one source feeding a whole sheet gets capped instead of the crew fighting every wet cell.
• Defenders build causeways. A patrolling defender that has to swim (or stalls at a shore) builds a permanent 2-wide cobblestone causeway across the water — flush with the surface, banks untouched, guard rails added automatically when the crossing is over lava. Patrol only; a defender in combat never stops to build.
• Causeways are roads, not litter: repeat patrols converge on the same crossing and reuse or extend the standing deck, and once a deck stands villagers simply walk it — in testing, a village that swam a water body constantly went to zero swimming once its causeway network settled.
• Gatherers no longer harvest bridge cobblestone over or beside liquid — village causeways AND player-built cobble bridges near water are both safe from them.

Fixed

• The gravel-stacking loop: a builder next to a water source no longer piles endless gravel columns trying to out-place the flow.
• Flooded template cells can no longer wedge a house forever — worst case the wet cell is tolerated and the build still completes.
• Catacomb stair shafts no longer wedge when they cut through an aquifer band.
• One water source flooding a carve layer no longer writes off the whole layer.
• Patrol log noise: liquid-response declines are pre-gated and throttled, so a mature village no longer floods the server log with them.

Under the hood

• New shared CausewayTraversalTrigger (Freedom CausewayPrimitive consumer) with per-destination cooldown ledger and JUnit-pinned throttle/quantizer policy; the Gatherer role is wired next.

Requires / compatible with

• Minecraft 1.21.1
• NeoForge 21.1+ (the Risen pack ships 21.1.244)
• Freedom Lib 0.10.1 or newer — REQUIRED, floor raised this release. ZV now refuses to load with older Freedom versions (previously it would load and then crash mid-game). Freedom Lib 0.10.1 is already the current CurseForge release; update it together with ZV.
• ZV-Houses 0.1.148+ (unchanged)
• Spells & Spellcrafting (unchanged; current release 2.12.63)

Migration notes

• Existing worlds carry over — no action needed. Standing villages pick up the new liquid behavior on first load.
