Changed
- Metal Melter now accepts raw metals and nuggets:
  - Raw Iron, Raw Copper, Raw Gold
  - Iron Nugget, Copper Nugget, Gold Nugget
- Added shared melt amount helper (`meltAmountForItem`) for melter input handling.

Patch update - 2026-04-10 (Metal Melter balance pass)

Changed
- Added balancing for metal melting yields:
  - Ingot = 1000 mb
  - Raw metal = 1250 mb (advanced melter bonus)
  - Nugget = exact 1/9 ingot (with remainder accumulation so 9 nuggets = 1000 mb total)

Fixed
- Horizontal side fluid intake is disabled, so side pipes can no longer insert fluid into Fluid Tank.
- Horizontal transfer loop now only uses sides configured to `OUTPUT`.

Patch update - 2026-04-11 (Fluid Tank side UI: ignore tank-to-tank adjacency)

Fixed
- Fluid Tank side I/O buttons no longer appear for sides touching another Fluid Tank block.
- Side visibility now ignores internal tank cluster connections and only reflects external connectable neighbors.

Patch update - 2026-04-11 (Fluid Network Controller smart-pipe-only info)

Patch update - 2026-04-17 (Client color handler event bus fix)

Fixed
- Fixed Fluid Tank block color handler registration bus in `ClientModEvents`.
- `RegisterColorHandlersEvent.Block` listener moved off MOD bus to avoid startup crash caused by wrong event bus group.

Patch update - 2026-04-17 (Client registry guard hardening)

Fixed
- Hardened client startup registry access in `ClientModEvents`:
  - menu screen registration now uses `RegistryObject.isPresent()` guard
  - Fluid Tank color handler registration now exits safely when `FLUID_TANK` registry object is not present
- This prevents hard startup crashes from direct `RegistryObject.get()` in edge-case load-order/registry states.

Patch update - 2026-04-17 (Color handler bus compatibility fix)

Fixed
- Fixed `RegisterColorHandlersEvent.Block` subscription bus for TEP Mini client events.
- Listener moved to `FORGE` bus to match event type (non-`IModBusEvent`) and avoid startup failure:
  - `BusGroup "modBusFortepmini" requires all events ... IModBusEvent ... RegisterColorHandlersEvent$Block doesn't`.

Patch update - 2026-04-17 (Client color handler class split + bus isolation)

Fixed
- Moved Fluid Tank block color registration into standalone client class:
  - `lt.laurynas.tepmini.client.ClientForgeEvents`
- Registered `RegisterColorHandlersEvent.Block` on `FORGE` bus in that standalone class.
- Removed nested color handler subscriber from `ClientModEvents` to avoid mixed bus-group registration ambiguity.
- This targets launcher error:
  - `BusGroup "modBusFortepmini" requires ... IModBusEvent ... RegisterColorHandlersEvent$Block doesn't`.

Patch update - 2026-04-17 (Fluid Tank window_fill rollback)

Changed
- Rolled back high-cardinality Fluid Tank `window_fill (0..100)` blockstate property.
- Restored window indicator rendering to existing `fill (1..14)` model set.

Fixed
- Reduced Fluid Tank blockstate/model complexity to prevent client startup/bake stalls.
- Removed `window_fill` handling from block/entity and blockstate resource mapping.

Patch update - 2026-04-17 (Fluid Tank window artifacts + seam reduction)

Fixed
- Transparent Fluid Tank now disables corner overlay models to avoid edge z-fighting artifacts:
  - all `fluid_tank_corner_*` multipart rules now require `transparent=false`
- Updated window wall models (`north/east/south/west`) to reduce seam artifacts:
  - switched render type to `cutout`
  - removed top/bottom faces from window wall elements (less horizontal seam between stacked blocks)
  - added UV mapping on window face to keep slit visually continuous across stacked blocks.

Changed
- Window slit rendering remains per-block, but now appears cleaner at block boundaries and side edges.

Patch update - 2026-04-17 (Fluid Tank selective window placement + visible level strip)

Changed
- Reworked transparent window placement rules in `fluid_tank.json`:
  - window walls and window fluid strips now render only on edge-middle positions of a side
  - center and corner positions are excluded
- Generated explicit side cases so each window is shown only when exactly one adjacent orthogonal direction is open (edge-middle behavior).

Fixed
- Improved fluid level visibility in window strip:
  - regenerated `fluid_tank_window_fluid_1..14` with thicker/deeper geometry behind slot
  - keeps tint color by fluid type and fill-based height.
- Reduced edge shimmer:
  - switched window wall models to `solid` render type
  - removed overlapping transparent surface usage in window frame pieces.

Patch update - 2026-04-17 (Fluid Tank Window moved to dedicated block)

Added
- New block: `fluid_tank_window` (dedicated visual monitor for Fluid Tank clusters).
- New block entity: `FluidTankWindowBlockEntity`.
- New crafting recipe and loot table for `fluid_tank_window`.
- New block/item/lang entries and creative tab registration.
- New blockstate+models for window monitor:
  - front icon shows fluid type item
  - progress bar shows cluster capacity fill level.

Behavior
- `fluid_tank_window` can be placed only on a horizontal side adjacent to a Fluid Tank.
- Only one window can be placed per connected Fluid Tank cluster.
- Window auto-updates from connected tank cluster every few ticks:
  - fill 0..14 based on stored/capacity
  - icon mapping:
    - molten metals -> ingot icon
    - water/lava -> bucket icon
- If attached tank is removed, window block removes itself.

Changed
- Removed old Fluid Tank GUI `Window ON/OFF` control.
- Legacy transparent tank-window visual path disabled in practice:
  - Fluid Tank no longer renders old embedded window models.
  - Fluid Tank visuals now stay on standard wall/surface rendering.

Client
- Added color handler for `fluid_tank_window` progress bar tint based on displayed fluid.

Patch update - 2026-04-17 (Fluid Tank Window missing texture fix)

Fixed
- Replaced `fluid_tank_window` icon model texture sources from `minecraft:item/*` to local block textures under:
  - `assets/tepmini/textures/block/window/icon_*.png`
- Added custom icon texture set for:
  - none, water_bucket, lava_bucket, milk_bucket, iron_ingot, copper_ingot, gold_ingot.
- Updated all `fluid_tank_window_icon_*.json` block models to use `tepmini:block/window/icon_*` paths.

Result
- Removed purple/black missing-texture cube on `fluid_tank_window` front display.

Patch update - 2026-04-17 (Fluid Tank GUI split)

Changed
- `Fluid Tank` GUI was simplified to configuration-only view:
  - side I/O buttons
  - mini tool slot
  - player inventory
- Removed fluid information lines and fill bar from `Fluid Tank` GUI.
- Added guidance text in `Fluid Tank` GUI that tank status is now shown in `Fluid Tank Window`.

Window UI
- `Fluid Tank Window` remains the full status GUI for tank cluster monitoring:
  - fluid type
  - stored/capacity in mL
  - fill level and percent
  - connected tank block count
  - visual fluid icon + progress bar

Patch update - 2026-04-17 (Fluid Tank Window GUI visual polish)

Changed
- Reworked `Fluid Tank Window` GUI layout for clearer readability.
- Added dedicated right-side icon zone with framed background.
- Enlarged fill progress bar to a wide bottom row in context panel.
- Improved text row spacing and simplified status wording for faster scan.
- Kept inventory panel styling aligned with other machine GUIs.

Patch update - 2026-04-17 (Fluid Tank Window GUI spacing cleanup)

Changed
- Moved `Fluid Tank Window` title lower with safe top padding.
- Removed icon type text label (`Ingot/Bucket`) from context panel.
- Removed decorative icon border frame for cleaner minimal icon display.
- Enlarged inventory panel and moved inventory label/slots down to prevent text overlap with panel border.

Patch update - 2026-04-17 (Fluid Tank + Window requested layout pass)

Changed
- Fluid Tank Window:
  - `Fill` line now shows only percentage value.
  - Inventory slots were aligned with drawn grid by syncing menu slot Y positions.
  - Fluid icon was moved lower for better visual alignment.
- Fluid Tank:
  - Removed `Side configuration` text block from top panel.
  - Reworked top content to a single full-width side I/O panel.
  - Rearranged side buttons into a wider two-column layout.
  - Moved tool slot and labels to match new full-width panel.
  - Enlarged/lowered inventory section and moved inventory label down to avoid border overlap.

Patch update - 2026-04-17 (Funnel block v1)

Added
- New block: `funnel`.
- New block entity: `FunnelBlockEntity`.
- Added `funnel` recipe, loot table, item definition, blockstate/model/item model, EN/LT localization, and pickaxe/stone-tool tags.
- Added `funnel` to functional creative tab.

Behavior
- `RMB` with `Water Bucket` or `Lava Bucket` pours fluid into Funnel.
- `RMB` with empty `Bucket` extracts fluid back (when at least `1000 mL` available and fluid has matching bucket form).
- Funnel outputs fluid only downward (`bottom output`) each tick.
- Downward output supports direct receiver or connected pipe network routing via existing fluid network helper.

Patch update - 2026-04-17 (Funnel opaque + Bucket Filler)

Changed
- Funnel top/grate visuals were updated to non-transparent textures (no cutout transparency).

Added
- New machine block: `bucket_filler`.
- Added `Bucket Filler` block entity, menu, and GUI screen.
- Added full resources for `bucket_filler`:
  - blockstate/model/item model/item definition
  - recipe
  - loot table
  - localization EN/LT
  - pickaxe/stone-tool tags
  - tier 1 pipe connectable tag entry

Behavior
- `Bucket Filler` accepts fluid from pipe network only when an empty bucket is inserted in its bucket slot.
- Supported fill fluids: `Water` and `Lava`.
- Once internal fluid reaches one bucket (`1000 mL`), inserted empty bucket is converted into filled bucket.

Patch update - 2026-04-17 (Funnel pipe sides + molten bucket textures)

Changed
- `Funnel` now implements side-aware tier 1 pipe connect rules:
  - only `UP` and `DOWN` can connect
  - horizontal sides no longer connect to pipes
- `Funnel` keeps pipe fluid input support from `UP` and fluid output routing downward.
- `Funnel` now refreshes adjacent tier 1 pipe connection states on placement to apply side rules immediately.
- `MoltenBucketItem` bucket-empty behavior was expanded so ground/block right-click placement path is handled more reliably.

Added
- Added missing molten bucket item definition files:
  - `assets/tepmini/items/molten_iron_bucket.json`
  - `assets/tepmini/items/molten_copper_bucket.json`
  - `assets/tepmini/items/molten_gold_bucket.json`
- Added missing molten bucket item model files:
  - `assets/tepmini/models/item/molten_copper_bucket.json`
  - `assets/tepmini/models/item/molten_gold_bucket.json`

Result
- Missing texture issues for molten bucket items are resolved by complete item/model registration files.

Patch update - 2026-04-17 (Casting Table dump routing fix for Funnel)

Changed
- `Casting Table` dump-to-pipe logic now uses shared `FluidPipeNetwork` routing instead of direct `FluidTank`-only search.
- Dump can now deliver fluid to any valid `PipeFluidReceiver` on the network path, including `Funnel` (with top input rules).

Result
- `Dump` works when pipeline path leads through/into `Funnel` instead of requiring direct `Fluid Tank` endpoint.

Patch update - 2026-04-17 (Distinct molten visuals: buckets + world placement)

Changed
- Molten bucket world placement is now type-aware:
  - `Molten Iron Bucket` places `molten_iron_fluid` block
  - `Molten Copper Bucket` places `molten_copper_fluid` block
  - `Molten Gold Bucket` places `molten_gold_fluid` block
- Added dedicated molten world block registrations and models using existing molten fluid textures.
- Updated molten bucket item models so they no longer all look identical:
  - iron uses bucket + iron ingot overlay
  - copper uses bucket + copper ingot overlay
  - gold uses bucket + gold ingot overlay

Added
- New block class: `MoltenFluidBlock`.
- New blockstates/models:
  - `molten_iron_fluid`
  - `molten_copper_fluid`
  - `molten_gold_fluid`

Patch update - 2026-04-17 (Molten placed fluid visual style)

Changed
- Molten placed blocks were switched from full solid cube look to fluid-style render:
  - translucent render type
  - lowered liquid height model (not full cube)
  - dedicated still textures per metal retained
- Molten placed blocks now have:
  - no collision
  - no occlusion
  - replaceable behavior
  - light emission per molten type

Result
- Poured molten iron/copper/gold no longer looks like a solid block and is visually distinct per metal.

Patch update - 2026-04-17 (Real flowing molten fluid system)

Changed
- Replaced static molten fluid-style blocks with real Forge flowing fluids:
  - `ForgeFlowingFluid.Source`
  - `ForgeFlowingFluid.Flowing`
  - `LiquidBlock` fluid blocks
- Molten buckets are now standard `BucketItem` instances bound to real fluid sources.
- Molten fluid rendering now uses vanilla lava still/flow sprites with per-fluid tint:
  - iron: gray
  - copper: copper-orange
  - gold: gold-yellow
- Client render layer registration now includes both source and flowing molten fluids.

Removed
- Removed deprecated static-fluid implementation classes:
  - `MoltenFluidBlock`
  - `MoltenBucketItem`
- Removed old static molten blockstate/model resources no longer used by the flowing system.

Result
- Molten Iron/Copper/Gold now behave as true fluids in-world (flow + spread), instead of static pseudo-fluid blocks.
- Bucket placement/extraction path is now aligned with vanilla fluid bucket behavior.

Patch update - 2026-04-17 (Molten color tuning pass)

Changed
- Adjusted molten fluid visual tint palette to requested tones:
  - Iron -> more silver
  - Copper -> more orange/rust (ryza)
  - Gold -> richer gold
- Synced these colors across:
  - real flowing fluid tint (`MoltenFluidType`)
  - Fluid Tank bars (`fluidBarColor`)
  - Fluid Tank Window progress tint (`progressBarColor`)

Patch update - 2026-04-17 (Per-metal flowing texture split)

Changed
- Real flowing molten fluids no longer use shared vanilla lava texture.
- Each molten fluid now has dedicated texture pair:
  - `molten_iron_still` + `molten_iron_flowing`
  - `molten_copper_still` + `molten_copper_flowing`
  - `molten_gold_still` + `molten_gold_flowing`
- Updated fluid type bindings so Iron/Copper/Gold read their own still/flowing assets.
- Removed global tint forcing for molten fluids (set to neutral white), so texture color is preserved directly.

Added
- New flowing texture assets:
  - `assets/tepmini/textures/block/fluid/molten_iron_flowing.png`
  - `assets/tepmini/textures/block/fluid/molten_copper_flowing.png`
  - `assets/tepmini/textures/block/fluid/molten_gold_flowing.png`

Patch update - 2026-04-17 (Molten fluid animation + bucket fill visuals)

Changed
- Molten fluid textures are now animated for both still and flowing states.
- Generated 4-frame animated sheets (`16x64`) for:
  - `molten_iron_still/flowing`
  - `molten_copper_still/flowing`
  - `molten_gold_still/flowing`
- Added animation metadata (`.mcmeta`) with interpolation:
  - still textures use slower frame time
  - flowing textures use faster frame time

- Molten bucket item visuals were changed from ingot overlay to fluid-fill overlay:
  - `molten_iron_bucket`
  - `molten_copper_bucket`
  - `molten_gold_bucket`
- New bucket fill item textures added:
  - `textures/item/molten_iron_fluid.png`
  - `textures/item/molten_copper_fluid.png`
  - `textures/item/molten_gold_fluid.png`

Result
- In-world molten fluids now visually move (animated), so they look less static/fake.
- Bucket icons now look closer to water/lava bucket style (visible fluid fill instead of ingot icon).

Patch update - 2026-04-17 (Animation speed + bucket icon style refinement)

Changed
- Slowed molten texture animation speed to look more natural:
  - still fluids: `frametime 10`
  - flowing fluids: `frametime 8`
- Kept interpolation enabled for smoother movement.

- Refined molten bucket fluid overlay icons to match vanilla-like bucket fill look:
  - replaced full-square fill with bucket-interior mask shape
  - added subtle highlight/shadow gradient for depth
  - preserved per-metal color identity (iron/copper/gold)

Result
- Fluid movement appears less fast/arcade-like.
- Bucket icons now visually match water/lava bucket style more closely.

Patch update - 2026-04-17 (Vanilla-style molten bucket icons)

Changed
- Rebuilt molten bucket item textures directly from vanilla bucket style composition.
- Molten bucket models now use full per-item textures (single layer), instead of custom overlay stack.
- Updated models:
  - `models/item/molten_iron_bucket.json`
  - `models/item/molten_copper_bucket.json`
  - `models/item/molten_gold_bucket.json`
- Added new full icon textures:
  - `textures/item/molten_iron_bucket.png`
  - `textures/item/molten_copper_bucket.png`
  - `textures/item/molten_gold_bucket.png`

Result
- Molten bucket icons now match vanilla bucket silhouette/shading style while keeping distinct metal fluid colors.

Patch update - 2026-04-20 (MiniKoro pet system expansion + UI polish)

Added
- Added MiniKoro `Shower` action button and server-side action handling.
- Added side-panel UI animations for MiniKoro:
  - smooth stat bar transitions
  - slide-in/out animation for `Pet Info` and `Pet Stats` side menus.
- Added dynamic pet stat scaling system by animal type and level:
  - per-type base values
  - per-level growth values
  - real max stat calculation per pet.

Changed
- MiniKoro GUI layout was reworked to avoid text/button overlap:
  - status line moved
  - button rows resized/repositioned
  - player inventory moved lower.
- `Pet Stats` panel now shows real numeric values as `current/max` based on pet type and level.
- Sleep energy gain now follows sleep progression timing (removed extra fast sleep boost path).
- MiniKoro item reequip animation handling was adjusted so continuous NBT updates do not trigger hand flicker.

Fixed
- Fixed issue where closing MiniKoro during sleep could look like continuous RMB/use animation.
- Fixed unnecessary capsule persistence writes by saving MiniKoro capsule data only when NBT actually changes.
- Fixed pet catch-up stat changes after long inactivity:
  - if capsule is not in MiniKoro, stats are frozen
  - after game-off/long pause, stats do not jump forward
  - sleep timer is also frozen during inactivity.

Patch update - 2026-04-20 (Fluid Tank water animation vanilla restore)

Changed
- Fluid Tank water surface models were switched from custom local water texture reference to vanilla Minecraft water texture:
  - from `tepmini:block/fluid/water_still`
  - to `minecraft:block/water_still`
- This restores original vanilla water animation style inside Fluid Tank water surfaces.

Patch update - 2026-04-20 (Fluid Tank Window top placement support)

Added
- `Fluid Tank Window` can now be placed on top of `Fluid Tank` blocks (upper face), not only on horizontal sides.

Changed
- Window attachment/survival logic now supports `facing=up` and links to the tank block below.
- Window blockstate/model mapping now includes `up` orientation rendering variants.

Fixed
- Window cluster uniqueness check now also accounts for top-placed windows in the same connected tank cluster.

Patch update - 2026-04-20 (Casting Table input control + smart metal selector)

Added
- Added `In ON/OFF` button in Casting Table GUI to control fluid intake.
- Added `Metal` selector button in Casting Table GUI for molten input filter:
  - `Auto -> Iron -> Copper -> Gold`
  - selector is active only when Smart Pipe is connected.

Changed
- Casting Table now supports dedicated fluid intake state independent from processing state:
  - when intake is `OFF`, table rejects all incoming pipe fluids.
- Molten input filtering now applies for Smart Pipe input:
  - selected metal accepts only matching molten fluid from smart-pipe side.
- Casting Table GUI top controls were compacted to fit:
  - output mode
  - run/stop
  - intake on/off
  - dump
  - clean

Compatibility
- If no Smart Pipe is connected, Metal selector remains visible but disabled (`Smart pipe required` hint is shown in status text).

Patch update - 2026-05-07 (TEP Mini model warnings fix)

Fixed
- Fixed missing `particle` texture warnings for Fluid Tank Window overlay models:
  - `models/block/fluid_tank_window_icon_*.json`
  - `models/block/fluid_tank_window_bar_*.json`
- Added molten fluid blockstate coverage to remove `Missing model for variant` warnings:
  - `blockstates/molten_iron_fluid.json`
  - `blockstates/molten_copper_fluid.json`
  - `blockstates/molten_gold_fluid.json`
- Added shared molten fluid block model:
  - `models/block/molten_fluid.json` (`forge:block/fluid` parent)
