WyWF

Added

• only modifier (only, just, single, только, лишь, одна): accept seeds with exactly one instance of the structure within range. Example: only desert pyramid — exactly one pyramid within ~500 blocks.
• between modifier (between, mid, middle, от, между, диапазон): structure must be within a specific distance range. Examples: village between 500 to 800, 500..800 village, деревня от 500 до 800. Supports separators .., to, do, до.
• some N count: some now accepts an explicit count. Example: some 4 village — at least 4 villages within ~320 blocks. some village (no number) defaults to at least 2.
• Modifier display in search log: Terms now show modifier details: some 4 minecraft:village, between 500..800 minecraft:village_plains.
• Mod Menu + YACL config screen: settings are now accessible via Mod Menu (config button). Uses YACL for a beautiful categorized UI with sliders, dropdowns, and toggles. Both Mod Menu and YACL are optional — the mod works without them (settings via config/wywf.json). Available settings: query language, thread mode, scan radii, sample step, candidate count, stop-at-first toggle, sort-by-distance toggle.
• "Did you mean?" with consonant-skeleton matching: when the query contains misspelled words, the mod suggests corrections by matching consonant skeletons (e.g. "mnsn" → "mansion", "vllg" → "village", "dsert" → "desert"). Shows ALL corrections at once. Works even when ALL words are misspelled.
• ExclusionZone enforcement: structure placements now respect vanilla exclusion zones — a structure whose placement is blocked by a nearby structure from another set is correctly rejected.
• Spawn block prediction improvement: spawn block scanning now covers ±2 chunks (32 blocks) around the origin, matching vanilla's spawn search area, instead of only the origin chunk.
• Sort candidates by distance: when ON, the final candidate is chosen by distance to the nearest structure (closest first), rather than randomly. Default: OFF. Toggle in Mod Menu → Search.
• Time limit: maximum search time before stopping. Default: 30 minutes, minimum: 5 minutes. When reached, a dialog asks whether to use the best candidate found, double the limits and search more, or cancel.
• Max seeds to check: hard limit on seeds evaluated. Default: 10,000,000, minimum: 1,000,000. When reached, same dialog as time limit. Both limits enforce minimums — inputting a lower value snaps to the minimum.
• Implicit biome for structures: when a structure has a unique natural biome and the query doesn't specify one, the biome is auto-added (mansion → dark_forest, desert_pyramid → desert, swamp_hut → swamp, ocean_monument → ocean, village_desert → desert, village_plains → plains, village_taiga → taiga, village_savanna → savanna, village_snowy → snowy_plains, etc.).
• Reverse variant mapping: structure variants (village_desert, village_plains, etc.) now resolve back to their base structure (village) for placement checks. Without this, the prefilter couldn't find the structure in StructureSets and discarded ALL seeds.

Changed

• Distance constants tuned:
  • near: 200 blocks (was default radius).
  • in: 64 blocks.
  • far: 500–1000 blocks (was ~1000–2000).
  • some: 320 blocks scan radius.
  • only: 500 blocks scan radius.
• NEVER prefilter removed. The structure placement prefilter for never was too aggressive for common structures (villages, etc.) — it mathematically could never reject within the search radius. Full validation handles never correctly without a prefilter.
• SOME/ONLY re-scan uses biome-aware positions() (not placement-only). BETWEEN still uses positionsPlacementOnly().

Fixed

• NEVER false positives: never plains village previously accepted seeds with a village within range. Reverted to firstPositionPlacementOnly which correctly resolves structure variants (e.g. village_plains → all village placements via minecraft:village Structure key).
• SOME re-scan radius: structureScanRadiusChunks for SOME returned the full searchRadiusChunks (40 chunks / 640 blocks) instead of chunks(SOME_BLOCKS) (20 chunks / 320 blocks). Villages at 668+ blocks were incorrectly shown for some 4 village.
• BETWEEN parsing: trailing 500 to 800 after a term (like village 500 to 800) was not attached. Now retroactively applied to the last term at end-of-loop.
• BETWEEN re-scan display: positions outside [betweenMin, betweenMax] were shown. Now filtered correctly.
• evalBiomeTermDirect step: ONLY/BETWEEN biome cases now use effectiveStep(quartY) for correct underground biome sampling.
• evalBiomeTermDirect BETWEEN biome bug: now uses BiomeField.nearestDistanceBlocks(key, betweenMin, betweenMax) for correct range matching.
• splitBetweenWord helper: handles single-word BETWEEN patterns (500..800, 500до800, 500to800, 500do800).
• Thread safety: structure cache race condition. SeedValidator.structureCache inner maps were plain HashMap shared across multiple search threads — could cause ConcurrentModificationException or corrupted data during concurrent reads. Changed to ConcurrentHashMap.
• Thread safety: WorldContext.sampler() non-volatile lazy init. Multiple threads could see a partially-constructed Climate.Sampler object. Added volatile.
• stopReason not reset between searches. If search A finished with a stop reason (e.g. "time limit reached"), search B's completion handler would show the wrong reason. Now cleared in start().
• Duplicate implicit biomes. addImplicitBiomes could add the same biome multiple times if two structures mapped to the same biome (e.g. "ocean monument ocean ruins" → two ocean biome terms). Now tracks already-added biomes.
• Dangling modifier applied to wrong word. "near xyz village" — the NEAR modifier was intended for "xyz" (which was ignored), but was incorrectly applied to "village". Now modifiers are reset when a word is ignored.
• All threads named the same. Worker threads were all named "WYWF-Search-{count}", making them indistinguishable in thread dumps. Now uses an AtomicInteger counter.
• Progress counter drift in linear (biome-only) search. SearchWorker.runLinear did not increment globalSeedCursor on error, causing the progress display to undercount checked seeds. runSplit already did this correctly.
• Duplicate synonym warnings. Removed duplicate structure entries (desert_pyramid, jungle_pyramid, swamp_hut, igloo, monument) that shared synonyms with generic entries and caused first-wins warnings at startup. Unique synonyms from removed duplicates were merged into the generic entries. Village variant entries (village_plains, etc.) kept for compound binding.
• woodland synonym conflict. Removed "woodland" from mansion synonyms — it was already claimed by the forest biome entry.
• MC lang parser warning. Moved synonym data files from lang/ to data/ (assets/wywf/data/en_us.json, ru_ru.json) to prevent Minecraft's resource loader from attempting to parse them as language files (which expected string values, not arrays). Updated KeywordDictionary loader paths.
• Empty query handling. SeedSearcher.start() now fires onFound with a SearchResult(primaryDescription=null) when all terms are filtered out (e.g. unsupported biomes/structures for the MC version), instead of silently never completing — the UI no longer gets stuck on "Preparing...". The null description routes to SearchLimitReachedScreen instead of trying to create a world with seed 0.
• Text rendering on MC 26.x. GuiGraphicsExtractor.text() and centeredText() check ARGB.alpha(color) == 0 and skip the draw. All UI text colors now use 0xFFFFFFFF (with alpha byte) instead of 0xFFFFFF, which was silently dropped.
