+## 0. 実施結果（2026-08-11） + +完全生成の candidate plan、quality retry、overscan、full finalist、post-admin transport、visible-crop / seam finalizer は削減していない。実施したのは、公開結果へ反映されない不具合の修復、静的に無効と確定した処理の削除、同一 fixture の共有、テスト実行基盤の修復、完全等価なコピー／比較処理への置換である。 + +### 実施済み + +- A-01: transport 配列の stale alias を解消し、late cleanup が公開 `features.*` と同じ配列を処理するよう修正。配列同一性 invariant も追加した。 +- A-02 / A-07c / A-12 / A-14g: suite registry を一元化し、未知 suite / group を即失敗、generic determinism seed を修正、出力収集を共有 byte counter と chunk 連結へ変更し、test failure と infrastructure failure を分離した。 +- A-04 / A-05: 未使用の全域 `barrierCost` / `corridorCost` 構築と、結果を破棄していた結合 railway prune を削除した。 +- A-07: default の重複 seed 999 determinism を削除し、seed 54321 の variation assertion を既存 terrain map へ移した。coverage-hole best-of は既存 coverage suite に統合し、同一初期 map を共有する。 +- A-07: temp/debug 3本、置換済み best-of 単独テスト、旧 determinism helper を削除した。raw-worker browser harness 2本も、上位の実アプリ browser suite に統合済みのため削除した。 +- A-11: source text は core suite でのみ遅延読込し、`mapPipeline.js` の二重読込と `test.js` 自己読込を除去した。typed-array determinism 比較は配列化／JSON化せず直接比較する。 +- A-14a: viewport raster はセル単位 lookup から、clipping を保つ typed-array row copy へ置換した。負座標・fallback cell の回帰検査を追加した。 +- A-14f: production fixture の seed hash と最大 lasso 構築を `tests/production-fixtures.mjs` に共通化した。 +- A-15: local dead function / closure、未使用 import・束縛・引数、`stableWorldTerrain`、無効な radial fallback、no-op UI、未使用 CSS selector / custom property / transition、同一 CSS block を整理した。 +- repo 内参照ゼロかつ package 公開定義もない `mapAdminSeedLifecycle.js`、`adminRegions.js`、`mapGenerator.js` を削除した。 +- default / release / browser manifest を README に記載し、Windows の Edge を direct-CDP fallback として検出できるようにした。 + +### 検証結果 + +- 変更前 canonical baseline: terrain 3件、patch 3件の計6件が既存失敗。runner が通常の assertion failure まで infrastructure failure に誤分類していた。 +- 変更後: unit、coverage、core、terrain-name、admin、patch-large、determinism 4 seed、r10 exact-production、r11 selection-native-production、r11.8 を実行。新規の機能失敗はなく、terrain 3件と patch 3件は変更前と同一である。 +- r10 は optimized / exhaustive の variant と最終 score が一致し、簡易 human / transport draft を公開していない。r11 は selection-native full production と transport hard gate を通過した。 +- 実アプリ browser smoke は preview 公開、canvas 変更、完全 stats、Apply、mirror ACK、bounded progress を通過した。一方、この環境では 60秒の性能予算に対して74.55秒であり、性能 gate は緩和していない。 +- r11.6 の3候補 full-production 比較は、この環境で旧130秒およびrunner 300秒を超えた。候補数を減らさず timeout の不整合だけを540秒／600秒へ修正したが、延長後の完走は未確認である。 + +### 未実施・保留 + +- runner が参照する r10 / r11 系テスト、Node wrapper、今回追加した fixture helper と本監査文書は作業ツリーでは未追跡である。Git index / commit の操作は行っていないため、採用時は runner・README・依存ファイルを同一 commit に含める必要がある。 +- A-06b / A-06d: rect-native terrain と旧 raw-draft worker protocol は repo 内未到達だが、export / message protocol の外部互換確認が必要なため削除していない。 +- `prepareProductionTerrain`、`generateMapAsync`、`generateAdminLayout` 等の未参照 export は、外部 direct import 契約を確定できないため残した。 +- A-08〜A-10、A-13、A-14b〜A-14e の高コスト反復・同期非同期統合は、全 seed / mode / shape の shadow 比較と座標・metadata の完全一致が必要である。観測 seed だけを根拠に pass を削除する変更は行っていない。 +- r11.5 / r11.7 / r11.8 の seed 共有統合、maximum-worker と selection-native の同一候補共有は、各契約を一つの worker lifecycle に移植する追加作業が必要である。 + +## 1. 監査の絶対条件 + +本監査の目的は、完全生成の内容を軽くすることではない。同じ完全生成を、不要な計算・複製・再走査・重複実装なしで実行できる状態にすることである。 + +### 1.1 禁止事項 + +次の変更は、処理時間やコード量が減っても採用対象外とする。 + +- terrain-scout、draft、proxy、private tile の内容を公開結果として再利用する。 +- geography、settlement、admin、transport、visible-crop finalizer、seam / quality audit のいずれかを省略する。 +- candidate 数、quality retry、overscan、探索範囲、経路制約、密度基準を性能目的で引き下げる。 +- admissible でない近似 score や経験的閾値により、勝ち得る候補を full production 比較前に捨てる。 +- terrain-routed path を直線、snapped line、簡易 connector へ置換する。 +- test の assertion、seed、異なる option の fixture、browser / worker / cancel / mirror 契約を、実行時間短縮だけを理由に削る。 +- quality gate を緩和し、処理が速くなったことを最適化の成功とみなす。 + +### 1.2 現行の完全生成契約 + +現行コードには、候補選別用の terrain-scout がある。これは公開可能な簡易生成ではなく、次の条件でのみ許容されている非公開の前段評価である。 + +- `src/mapPatchWorker.js:1969-1981` は full candidate 実行時に `_precomputedDraftCandidate: null` を明示し、再利用を exact terrain field に限定する。 +- `src/mapPatch.js:12945-12955` は公開候補で full patch candidate を生成し、簡略 geography / human / transport draft を再利用しない。 +- `src/mapPatchWorker.js:2158-2160` は `reusedWinningDraft: false`、`fullProductionFromTerrainOnly: true` を記録する。 +- `tests/r10-exact-production-worker.mjs:62-72` は optimized search と exhaustive full-production search の variant と score の一致、および簡略 output の非公開を検証する。 +- `src/mapPostAdminTransport.js:4008-4015` と `tests/r11.5-visible-quality-finalizer.mjs:115-120` は visible crop に full production finalizer を要求する。 + +この契約を弱める変更は、本監査の「短縮」には含めない。scout 自体の範囲を広げる案も出さない。 + +### 1.3 private tile の扱い + +大矩形生成では、一部の global repair を private tile 内で遅延し、組立後の selection 全体で実行する経路がある (`src/mapTransport.js:56-59,1318-1327`、`src/mapFeatures.js:2644-2659`)。これは、次の全条件を満たす場合に限り簡易生成とは扱わない。 + +- tile は単独で公開されない。 +- `src/mapPatch.js:12831-12837` の品質 soft path は `_internalTile === true` の場合だけである。 +- 組立後に authoritative trunk generation、terrain repair、seam audit、Initial Quality Oracle を完走する。 +- top-level candidate は同じ soft path を利用できない。 + +この境界は将来の refactor で崩れやすいため、明示的な invariant test を残す。 + +### 1.4 用語上の非対象 + +- `src/app.js` / `src/renderer.js` の `fastTerrain` は pan / zoom 中の描画省略であり、保存される map generation の簡略化ではない。 +- `src/mapAdminStage.js:212-264` の `simple administrative hierarchy` / `simpleHierarchyPrototype` は現行 production stage の方式名であり、別の軽量 generator への分岐ではない。名称だけを根拠に未使用・簡易生成とは判定しない。 +- `src/mapPatchWorker.js:2161` の `parallelDraftGeneration` は互換目的で残る旧 metadata 名で、現在の実体は terrain-scout である。改名する場合も protocol 互換を先に確認する。 + +### 1.5 最優先の結論 + +最優先で扱うべきなのは、単なる整理ではなく、実行した完全生成処理が公開結果へ反映されていない箇所と、検証していないテストが成功扱いになる箇所である。 + +1. `src/mapPostAdminTransport.js` の最終道路監査の一部は、古い配列別名を変更しており、公開される `features.*` には反映されない。 +2. `tests/test.js` は未知の suite 名でも実質的に検証をせず成功し得る。 +3. 地物生成では、どこからも使われない2枚の全画面コストラスタを毎回構築している。 +4. 鉄道の parallel prune は、一度目が一時配列だけを変更して結果を破棄し、その直後に実配列へ同種処理を繰り返す。 +5. repo 内から到達しないモジュール・関数群、到達不能な temp テスト、同一 seed / fixture の重複生成が複数ある。 +6. post-admin transport などの反復修復は削減余地が大きいが、順序依存が強い。出力等価性を証明せず、pass を省略・簡略化してはならない。 + +監査で分類した確信度は次の通り。 + +- **確定**: 現在の repo 内参照、値の使用、または配列同一性から、未使用・無反映・重複を静的に証明できる。 +- **条件付き**: repo 内からは未使用だが、外部 import、外部 CI、手動実行の契約が見えない。 +- **要計測**: 処理の反復や走査は多いが、代表 seed で差分ゼロというだけでは削除できない。全対象条件で不要と証明するか、同じ変換を一度で行う等価実装へ置換するもの。 + +## 2. 優先順位一覧 + +| ID | 優先度 | 分類 | 要点 | 判定 | 修正リスク |

A-01〜A-03。現状の無反映や偽成功を直すため、出力差分が発生し得る。 +- **意味を変えない除去:** A-04、A-05、A-15の確定項目。未使用結果または破棄済み結果だけを取り除く。 +- **外部契約確認後の除去:** A-06。repo 内参照ゼロだけで公開 API を消さない。 +- **完全生成の等価最適化:** A-07〜A-14。生成段階や品質基準は減らさず、同一計算の共有、workspace 再利用、全域走査の一括化、実装共通化だけを行う。 + +## 3. 公開結果へ反映されない、またはほぼ無意味な処理 + +### A-01. stale alias により final transport cleanup が公開結果へ反映されない + +**根拠** + +- `src/mapPostAdminTransport.js:1073-1077` で `features.minorRoads`、`nationalRoads`、`externalRoads`、`expressways`、`externalExpressways` を `const` のローカル別名へ保持する。 +- `src/mapPostAdminTransport.js:3838-3842` は `dedupePaths(..., { mutate: false })` の戻り値を `features.*` へ再代入する。 +- `src/mapTransportUtils.js:193-228` の `dedupePaths` は `mutate: false` の場合、新しい配列と座標列を返す。この時点で冒頭の別名は古い配列を指す。 +- その後の `src/mapPostAdminTransport.js:3886` は `pruneShortFinalTrunkSegments()` を呼ぶが、同関数の `3778-3813` は古い `expressways`、`nationalRoads`、`minorRoads` を変更する。 +- `src/mapPostAdminTransport.js:3891-3894` の shared-alignment / parallel-prune も古い配列を変更する。 + +このため、次の診断名で数えた変更は、公開される `features.*` に反映されない。 + +- `finalShortTrunkCleanupAfterService` +- `finalExpresswaySharedAlignment` +- `finalNationalSharedAlignment` +- `finalExpresswayParallelPruneExactOutput` +- `finalNationalParallelPruneExactOutput` + +なお、直後の major-city link 補完など、明示的に `features.*` を渡す処理まで無効という意味ではない。 + +**短縮・是正案** + +- 配列の identity を維持する in-place 正規化へ統一する、または再代入後はローカル別名を廃止し `features.*` だけを参照する。 +- 修正すると、今まで死んでいた prune が実際に出力を変える可能性がある。出力差分を仕様として確認し、`features.*` と処理対象の identity を検証する回帰テストを先に置く。 +- **禁止:** 無反映だった pass 自体を削除して「無駄を除いた」とはしない。本来要求された full final cleanup を実配列へ適用するのが先である。 + +### A-04. 不使用の全域コストラスタを毎回構築 + +**根拠** + +- `src/mapFeatureContext.js:64-65` は `barrierCost` と `corridorCost` の `Float32Array` を確保する。 +- 同ファイル `72-74`、`162-163` で全セルを走査し、hash を含む値を格納する。 +- `src/mapFeatures.js:94-95` は両者を分割代入するが、その後一度も読む箇所がない。repo 内にも別の利用者はない。 + +hidden generation の 354 × 279 = 98,766

+`src/mapPostAdminTransport.js` では、修復で経路を追加し、dedupe / prune を行い、service repair で再追加する流れが `3838-4006` と `4395-4701` に集中している。 + +主な呼び出し回数（関数定義を除く）は次の通り。 + +- `dedupePaths`: 69回 +- major-city national link 補完: 14回 +- major-city rail link 補完: 16回 +- major-city expressway link 補完: 12回 +- parallel corridor collapse: 15回 +- final parallel prune: 13回 +- rail / national ratio の densify: 9回 +- rail / national ratio の cap: 9回 + +`dedupePaths` は `mutate: false` の場合、重複がゼロでも全 path と全 `[x, y]` を複製する。さらに `src/mapTransportUtils.js:213-219` は各 path 内で署名関数を作り、`map` / `filter` / `join` を往復2回、逆順用の配列も生成する。 + +**短縮案** + +1. network ごとの revision / dirty flag を持ち、変更されていない配列の再正規化だけを省く。正規化の semantic boundary は移動しない。 +2. repair 群を上限付き収束ループへまとめる場合、従来の pass 順、上限、tie-break を維持し、state revision が不変のときだけ終了する。 +3. 各 stage の add / remove / replace 件数を seed corpus で記録する。ただし、観測した seed で0だったことだけを根拠に pass を削除しない。静的 precondition または shadow 実行との完全一致を削除条件にする。 +4. path signature は helper を外へ出し、一時配列を作らない添字走査にする。 + +順序を変えると地図出力が変わるため、一括統合はしない。これは完全生成 pass の削減案ではなく、同じ pass の重複実行・全量複製を対象にした等価最適化候補である。各変更で path 順序、座標列、debug counter、最終 hash の一致を要求する。 + +### A-09a. 自治体 topology repair の O(所有者数 × 全セル) 走査 + +`src/adminRegionsCore.js:5-97` の `enforceMunicipalityConnectivityStrict` は、全所有者の component を一度の全域走査で集める。一方 `repairAdminTopology` (`:117-143`) は所有者ごとに `Uint8Array(SIZE)` を確保し、全セルを走査する。同処理は `:1132`、`:1262` から呼ばれる。 + +**短縮案:** 共通の `collectComponentsByOwner` を一度実行し、中心 component の保護・再割当規則だけを各処理へ残す。owner 順、component 探索順、同点時の再割当先を変えない。 + +### A-09b. 人口再推定と合併反映の全域走査 + +- `src/mapAdminStage.js:386` で人口を推定する。 +- 合併があると `:478` で再推定し、その直後 `:500` でも無条件に再推定する。 +- 合併先ごとに `:459-461` が `adminId` 全域を再走査する。 +- 実体の `src/mapMunicipalDemography.js:13-42` もラスタ全域を走査する。 + +無合併でも推定2回、合併時は3回になり得る。合併先 remap を蓄積して最後に一度だけ全域へ適用し、変更なしなら初回推定を再利用、変更ありなら最後に一度だけ再推定できる。ただし、中間推定値を読む処理がないことを call graph と regression test の両方で確認し、人口モデル自体は変更しない。 + +### A-13. 小さな local connector ごとの全寸法 workspace + +`src/initialGenerationCrop.js:749-890` の `localConnector` は、小さな bbox と展開上限360で探索する一方、呼び出しごとに全マップ寸法の `Float32Array`、`Int32Array`、`Uint8Array` を確保・初期化する (`:768-774`)。open set も線形最小値探索と `splice` を使う (`:776-782`)。 + +**短縮案:** bbox 分だけの配列、世代番号付きの再利用 workspace、binary heap のいずれかへ置換する。類似する `src/mapPostAdminTransport.js:4201-4260` の near-miss endpoint repair と共通化できるが、hidden crop の寸法差は明示的に注入する。heap 化では同 cost の取り出し順が変わるため、既存の tie-break を key に含め、経路座標の完全一致を合格条件にする。 + +### A-14a. viewport raster をフィールドごと・セルごとにコピー + +`src/worldViewport.js:66-80` は各フィールドについて全 x / y を走査し、各セルで `worldIndexOf` を呼ぶ。この処理が `:205-208` から多数の raster に繰り返される。`src/initialGenerationCrop.js:110-118` には既に `subarray` + `set` による行単位コピーがある。 + +**短縮案:** 行ごとの source / destination 範囲を一度求め、範囲内を bulk copy、画面外だけ既存値で fill する。負の camera 座標、部分領域外、各 typed-array constructor について cell-by-cell 実装との完全一致を検証する。 + +### A-14b. admin target / compartment / output の反復走査 + +| 場所 | 現状 | 短縮案 | +|---|---|---| +|

の同期・非同期探索 + +`src/mapPatchWorker.js:1150-1518` と `:1522-2608` は、初期化、候補 prepare / evaluate / finalize、snapshot 構築を数百行規模で重複する。通常候補探索だけでも `:1241-1517` と `:2328-2607` がほぼ同じである。 + +**統合案:** search environment と候補処理を共通化し、同期 executor と yield / cancel 対応 executor の違いだけを wrapper に残す。候補数や full-finalization 数は減らさず、進捗イベント順、cancel 境界、transaction rollback、candidate ranking を契約テストで固定してから行う。 + +### A-10b. `mapPipeline` の同期・非同期版 + +`src/mapPipeline.js:273-386` と `:388-494` は terrain、geography、features、admin context、transport、出力組立を重複する。既に以下の仕様差がある。 + +- 同期版 `:285-294` は `_precomputedTerrainDraftCandidate` を扱う。 +- 非同期版 `:397-403` は `_precomputedDraftCandidate` だけを扱う。 +- matcher も `:169-180` と `:182-193` に近似重複する。 + +**統合案:** 共通 stage plan / core を作り、同期版は直列 drain、非同期版は yield / await を注入する。stage の省略ではなく同一 stage list の共有とし、同じ seed / option で生成 field、feature、debug、hash が一致することを必須にする。 + +### A-14c. preview 差分判定 + +`src/app.js:2625-2692` と `src/mapPatchWorker.js:1091-1148` が同じ field / feature 集合を別実装で比較する。worker 側の comparator (`:477-515`) は `Date`、`Map`、`Set`、`patchGenerated` を扱うが app 側は扱わず、fallback 時の意味が一致しない。 + +**統合案:** field 定数、structured comparator、delta builder を pure module に切り出す。 + +### A-14d. A* 系と influence cache + +- `src/mapPostAdminTransport.js:232-373` と `:375-474` は bounds、stamped workspace、8近傍、terrain cost、relaxation、traceback を重複する。`routeTerrainSearch(..., profile)` の共通 core にできるが、tie-break と探索順を完全に維持する必要がある。 +- `src/mapTransportUtils.js:46-56` の influence cache signature は path 数、総点数、端点座標の総和だけで、内部頂点だけが変わると衝突し得る。一方 `src/mapFeatures.js` は phase ごとに異なる label を多用して hit しにくい。path-set identity + revision + radius を key にし、変更時に invalidate する方が単純で安全である。 +- `src/mapFeatures.js:2161-2163` は同じ道路配列の結合を3回作るため、一度だけ hoist できる。 + +### A-14e.

-## Scope - -This step completes the cleanup work identified after Step 14. The goal is to remove dead/duplicated/compatibility-only code and avoid pointless transport repair work without changing the generator's intended map quality. The earlier Step 14 transport lifecycle remains conceptually intact: base transport -> pre-admin finalization -> post-admin transport -> output topology finalization. - -## Cleanup completed - -### Dead and compatibility-only code - -- Removed the remaining unused `nearestNetworkPoint` import. -- Removed unused local bindings such as the old renderer history flag and unused satellite-classification return binding. -- Removed test-only legacy name compatibility exports (`NAME_PARTS`, `generateTemplateName`). -- Removed retired name-generation fallback debug fields. -- Removed retired administration debug fields that were permanently zero after the older seed/snap pipeline was deleted. -- Removed stale comments referring to the deleted patch candidate cache. -- Reduced exports that were only used inside their own module. - -### Shared utilities / duplication - -- Centralized time measurement, world indexing, finite field access, nearest-point distance, and grid-path walking in `mapUtils.js`. -- Centralized administrative border-field averaging in `mapAdminShared.js`. -- Centralized transport path rasterization and occupancy connected-component labeling in `mapTransportUtils.js`. -- Reused the shared raster/component utilities from `mapTransport.js` and `mapOutput.js` instead of keeping separate implementations. -- Static audit now finds no unreachable runtime module, no unused runtime import/export/local top-level declaration, and no exact duplicate named function body among 773 scanned function bodies. - -### Pre-admin road connectivity - -`connectPreAdminRoadComponents()` previously could repeat a failed topology state up to 44–46 times. It now: - -- builds candidates only between different connected components, -- reuses the influence field while the path topology is unchanged, -- tries each candidate in the current topology state at most once, -- stops a round immediately when no candidate succeeds, -- rebuilds components only after an accepted connector changes topology. - -Eight-seed probing shows failed attempts are now bounded to 0–2 in the common cases and no-success states stop after one round rather than 46 rounds. - -### Gap-stitch candidate work - -The former gap-stitch pass enumerated tens of thousands of same-component near pairs only to discard them. Candidate indexing is now component-aware so same-component pairs are excluded before route construction. - -### Redundant road passes - -- Removed the effectively dead `nationalPrune` pass after national-road downgrade. -- Made the final minor-road dedupe conditional on an actual connector having been added. -- Removed obsolete constant transport debug fields associated with deleted passes. - -### Output road finalization - -The output lifecycle now performs required additions before the final prune: - -1. municipal-center local access, -2. required center stubs, -3. nearby endpoint connectors, -4. isolated-component pruning, -5. final component measurement. - -This removes the previous normal pattern of pruning first and then re-adding required roads. The final diagnostic is now `finalOutputRoadTopology`, measured after all output topology mutations. - -### Patch runtime regression found during cleanup - -Static refactoring exposed one missed call site where `createPatchContext()` was still passed the deleted local `worldIndex` identifier. Normal map-generation tests did not execute that path. A real Expansion probe raised `ReferenceError: worldIndex is not defined`; the call site was corrected to the shared `worldIndexOf` helper. Expansion and rollback were rerun after the fix. - -## Verification - -### Runtime validation - -`STEP15_VALIDATION.mjs` passes on the final source: - -- seeds 1 / 3 / 5: every municipal center has road access, -- road-cell coverage remains above the regression floor, -- pre-admin connectivity attempts are bounded and no-success rounds terminate, -- Expansion succeeds with a clean seam, -- footprint write escapes: 0, -- unresolved road portals: 0, -- unresolved rail portals: 0, -- forced quality failure restores fields, source map, patch history state, serial, and source-map object identity. - -Latest measured Expansion in this validation: 7.55 s in this container. - -### Eight-seed transport probe - -Seeds `1, 3, 5, 101, 777, 999, 2026, 12345` retain 100% municipal-center road coverage. The former 44–46 failed pre-admin connector retries are gone; observed attempts are 0–3 per seed. - -### Test shards - -All eight test shards pass individually on the final source: - -- core: 0 failures, 17.46 s -- terrain: 0 failures, 24.23 s -- admin: 0 failures, 14.01 s -- determinism-114514: 0 failures, 8.46 s -- determinism-12345: 0 failures, 8.00 s -- determinism-54321: 0 failures, 8.38 s -- determinism-777: 0 failures, 7.80 s -- determinism-999: 0 failures, 9.92 s - -Total measured shard wall time when run as separate invocations: 98.26 s. Every shard is below three minutes. - -The container tool used for this work applies a cumulative execution throttle/termination to long single tool invocations; consequently `test-all.mjs` could not be observed to finish as one monolithic invocation here even though each child suite completes independently. `STEP15_TEST_RESULT.json` records the authoritative per-shard verification rather than claiming a monolithic pass. - -### Static audit - -Final runtime source: - -- runtime modules: 35 -- reachable runtime modules: 35 / 35 -- runtime source size: about 1.21 MB -- unused imports found: 0 -- unused exported declarations found: 0 -- unused local top-level declarations found: 0 -- exact duplicate named function bodies found: 0 / 773 scanned -- retired compatibility/debug symbols remaining: 0 -- all JS/MJS files pass `node --check` - -## Packaging - -Two packages are produced: - -- `map_step15.zip`: clean development project with source, tests, Step 15 validation/report files, and patch. -- `map_step15_runtime.zip`: runtime-only package containing `index.html`, `styles.css`, and the 35 reachable runtime JavaScript modules. Tests, validation scripts, patches, notes, and old Step artifacts are excluded. - -## Remaining caution - -This cleanup deliberately avoids another redesign of the four lifecycle phases of the transport generator. Some output pruning may still legitimately remove isolated roads, and some isolated same-landmass municipal components may require terrain-aware connectors during final output. Those operations have functional purposes and were retained rather than treated as dead code. diff --git a/archive/generated-history/STEP15_STATIC_AUDIT.json

+++ /dev/null @@ -1,86 +0,0 @@ -# Step 17 — Alternative preview / apparent interruption fix - -## Diagnosis - -The Step 16 worker move removed the explicit UI-thread fallback, but it did not fix two UI semantics that could make a completed Alternative request look as if nothing had happened. - -1. Expansion quality selection internally searched consecutive terrain variants. A request for variant `N` could evaluate `N`, `N+1` (and sometimes `N+2`), while the next Alternative request for `N+1` evaluated an overlapping set. Both clicks could therefore select the same internal terrain variant. -2. `generatePatch()` could silently rerun the complete patch once after a quality/seam rejection. This made one Alternative click take roughly one or two complete patch attempts depending on the result. On a slow machine that produces the observed large wall-time variation and can cross an external/browser execution limit. -3. If an Alternative failed, the previous pending preview stayed on screen, but the failure message was transient. This looked like a successful generation that was not reflected. -4. Renderer raster caches inferred freshness from map metadata. There was no explicit preview revision in the key. -5. Patch controls stayed usable while a worker job was active, so repeated clicks could enqueue work and make completion ownership ambiguous. -6. The patch worker was reused after large jobs, allowing a high-water heap to survive across repeated Alternatives. - -## Changes - -### One Alternative click now means one exact variant - -Interactive patch generation passes: - -- `qualityTerrainAttempts: 1` -- `maxQualityRetries: 0` - -`mapPatch.js` now supports an explicit terrain-quality attempt count. The default non-interactive behavior remains unchanged; only the UI Alternative path uses the one-variant policy. - -This removes overlapping internal candidate sets. If variant `N` fails the quality gate, it is rejected and the user can request `N+1`; the UI no longer silently spends another whole-patch attempt on a different hidden variant. - -### Preview freshness is explicit - -Every successful preview receives a monotonically increasing `world.renderRevision` and its requested `previewVariant`. - -`worldViewport.js` propagates those values and `renderer.js` includes them in the stable raster cache prefix. A newly returned preview therefore cannot reuse a terrain/urban/prefecture-fill cache entry from an older preview merely because its dimensions and field types are the same. - -### Verify that a preview actually differs - -Before displaying a successful worker result, `app.js` compares the committed and preview worlds over the patch write area and counts: - -- changed cells -- terrain changed cells (`elevation`, `sea`, `landuse`, `populationDensity`) -- administration changed cells (`adminId`, `municipalityId`, `prefectureRegionId`) - -The persistent patch status reports those counts. If a result is genuinely identical, the UI says so explicitly instead of implying that a visual update was lost. - -### Unambiguous rendering - -After a successful patch worker result, the app performs one immediate full redraw of the new pending world. The previous fast-redraw + delayed-full-redraw pair was removed from this path. - -The progress text now distinguishes generation from rendering and reports both generation and render wall time. - -### Failure remains visible - -If an Alternative is rejected or the worker fails, the patch status now says either: - -- no preview was applied, or -- the previous preview variant is still being shown. - -This message remains in the patch controls instead of disappearing with the temporary progress overlay. - -### One active patch job - -Patch/Alternative/Apply/Discard/variant controls are disabled while a patch job is active. A generation request also invalidates any stale patch request. - -### One-shot patch workers - -A patch worker is terminated after every completed job. This releases the worker heap between Alternative clicks and prevents stale heavy-generation state from accumulating across previews. - -## Validation - -`STEP17_VALIDATION.mjs` runs two consecutive interactive-style variants from the same committed world using the browser worker module. - -Observed: - -- variant 0: 8.42 s, selected terrain variant 0 -- variant 1: 8.50 s, selected terrain variant 1 -- quality retry count: 0 for both -- seam status: clean for both -- elevation hashes: different -- sea-mask hashes: different -- administration hashes: different - -Therefore the two Alternative requests produce materially different world data and exact requested variants. - -All 8 existing test shards pass independently on the final Step 17 source with zero `NG:` assertions. All JavaScript/MJS files pass `node --check`. - -## Browser E2E note - -The available container Chromium is subject to a localhost navigation policy/interstitial, so a reliable in-browser pointer/canvas E2E could not be completed here. Worker execution, variant data differences, cache-revision wiring, and all generator regressions are tested directly. diff --git a/archive/generated-history/STEP17_TEST_RESULT.json b/archive/generated-history/STEP17_TEST_RESULT.json deleted file mode 100644 index 38fa4c0..0000000 --- a/archive/generated-history/STEP17_TEST_RESULT.json +++ /dev/null @@ -1,63 +0,0 @@ -{ - "ok": true, - "suites": [ - { - "suite": "core", - "failedAssertions": 0, - "fullMapGenerations": 4, - "elapsedMs": 16970, - "status": 0 - }, - { - "suite": "terrain", - "failedAssertions": 0, - "fullMapGenerations": 6, - "elapsedMs": 25008, - "status": 0 - }, - { - "suite": "admin", - "failedAssertions": 0, - "fullMapGenerations": 3, - "elapsedMs": 14863, - "status": 0 - }, - { - "suite": "determinism-114514", - "failedAssertions": 0, - "fullMapGenerations": 2, - "elapsedMs": 9447, - "status": 0 - }, - { - "suite": "determinism-12345", - "failedAssertions": 0, - "fullMapGenerations": 2, - "elapsedMs": 9000, - "status": 0 - }, - { - "suite": "determinism-54321", - "failedAssertions": 0, - "fullMapGenerations": 2, - "elapsedMs": 8428, - "status": 0 - }, - { - "suite": "determinism-777", - "failedAssertions": 0, - "fullMapGenerations": 2, - "elapsedMs": 7999, - "status": 0 - }, - { - "suite": "determinism-999", - "failedAssertions": 0, - "fullMapGenerations": 2, - "elapsedMs": 29472, - "status": 0 - } - ], - "totalElapsedMsReported": 121187, - "note": "Each shard executed independently on the final Step 17 source." -} \ No newline at end of file diff --git a/archive/generated-history/STEP17_VALIDATION.mjs b/archive/generated-history/STEP17_VALIDATION.mjs deleted file mode 100644 index 2580322..0000000 --- a/archive/generated-history/STEP17_VALIDATION.mjs +++ /dev/null @@ -1,112 +0,0 @@ -import assert from 'node:assert/strict';
