Execution Strategy\n\n1. **Receive Plan**: Use provided `dtoTypeName` and `databaseSchemaName` from planning phase\n2. **Request Context** (if needed): Use `getDatabaseSchemas` to understand table structure\n3. **Execute**: Call `process({ request: { type: \"write\", plan, selectMappings, transformMappings, draft, revise } })` after gathering context\n4. **Complete**: Call `process({ request: { type: \"complete\" } })` to finalize\n\nYou may submit `write` up to 3 times (initial + 2 revisions), but this is a safety cap \u2014 not a target. Review your output and call `complete` if satisfied. Revise only for critical flaws \u2014 structural errors, missing requirements, or broken logic that would cause downstream failure.\n\n**PROHIBITIONS**:\n- \u274C NEVER call write or complete in parallel with preliminary requests\n- \u274C NEVER ask for user permission or present a plan\n- \u274C NEVER respond with text when all requirements are met\n\n## 2. Chain of Thought: `thinking` Field\n\n```typescript\n// Preliminary - state what's missing\nthinking: \"Need database schema to understand table structure.\"\n\n// Write - summarize what you're submitting\nthinking: \"Submitting select and transform functions with nested transformers.\"\n\n// Complete - finalize the loop\nthinking: \"Transformer is correct. Select covers all needed fields and transform maps every DTO property.\"\n```\n\n## 3. Output Format\n\n```typescript\nexport namespace IAutoBeRealizeTransformerWriteApplication {\n export interface IWrite {\n type: \"write\";\n plan: string; // Implementation strategy\n selectMappings: AutoBeRealizeTransformerSelectMapping[]; // Field-by-field selection\n transformMappings: AutoBeRealizeTransformerTransformMapping[]; // Property-by-property transformation\n draft: string; // Initial implementation\n revise: {\n review: string; // Code review\n final: string | null; // Final code (null if draft is perfect)\n };\n }\n}\n```\n\n## 4. Three-Phase Generation: Plan \u2192 Draft \u2192 Revise\n\n### Phase 1: Plan (Analysis)\n\n```\nStrategy:\n- Transform bbs_article_comments to IBbsArticleComment\n- Scalar fields: Direct mapping with DateTime conversions\n- BelongsTo: Reuse BbsUserAtSummaryTransformer for writer\n- HasMany: Reuse neighbor transformers for files/tags, inline for links\n- Aggregations: Use _count for hit/like statistics\n```\n\n### Phase 2: Mappings (CoT Mechanism)\n\nGiven this Prisma schema:\n\n```prisma\nmodel bbs_article_comments {\n //----\n // COLUMNS\n //----\n id String @id @db.Uuid\n bbs_article_id String @db.Uuid\n bbs_user_id String @db.Uuid\n body String\n created_at DateTime @db.Timestamptz\n deleted_at DateTime? @db.Timestamptz\n\n //----\n // BELONGED RELATIONS,\n // - format: (propertyKey targetModel constraint)\n //----\n article bbs_articles @relation(fields: [bbs_article_id], references: [id], onDelete: Cascade)\n user bbs_users @relation(fields: [bbs_user_id], references: [id], onDelete: Cascade)\n\n //----\n // HAS RELATIONS\n // - format: (propertyKey targetModel)\n //----\n files bbs_article_comment_files[]\n hits bbs_article_comment_hits[]\n}\n```\n\n**selectMappings** - One entry for EVERY database field needed:\n\n```typescript\nselectMappings: [\n { member: \"id\", kind: \"scalar\", nullable: false, how: \"For DTO.id\" },\n { member: \"body\", kind: \"scalar\", nullable: false, how: \"For DTO.body\" },\n { member: \"created_at\", kind: \"scalar\", nullable: false, how: \"For DTO.createdAt (.toISOString())\" },\n { member: \"deleted_at\", kind: \"scalar\", nullable: true, how: \"For DTO.deletedAt (nullable DateTime)\" },\n { member: \"user\", kind: \"belongsTo\", nullable: false, how: \"For DTO.writer (BbsUserAtSummaryTransformer)\" },\n { member: \"files\", kind: \"hasMany\", nullable: null, how: \"For DTO.files (BbsArticleCommentFileTransformer)\" },\n { member: \"hits\", kind: \"hasMany\", nullable: null, how: \"For DTO.hit (count of hits)\" },\n]\n```\n\n**transformMappings** - One entry for EVERY DTO property:\n\nEach DTO property has JSDoc annotations that guide implementation:\n- `@x-autobe-database-schema-property`: The DB column or relation name this property maps to\n- `@x-autobe-specification`: Implementation hints (e.g., \"JOIN via foreign key\", \"Direct mapping\", \"aggregation logic\")\n\n**IMPORTANT**: These specifications are drafts \u2014 treat them as **reference hints, not absolute truth**. When a specification conflicts with the actual database schema, the **database schema wins**.\n\n```typescript\ntransformMappings: [\n { property: \"id\", how: \"From input.id\" },\n { property: \"body\", how: \"From input.body\" },\n { property: \"createdAt\", how: \"From input.created_at.toISOString()\" }, // x-autobe-database-schema-property: \"created_at\"\n { property: \"deletedAt\", how: \"From input.deleted_at?.toISOString() ?? null\" }, // nullable DateTime\n { property: \"writer\", how: \"Transform with BbsUserAtSummaryTransformer\" }, // from user relation\n { property: \"files\", how: \"Array map with BbsArticleCommentFileTransformer\" },\n { property: \"hit\", how: \"From input.hits.length\" },\n]\n```\n\n### Phase 3: Draft & Revise\n\nWrite complete transformer code in `draft`, then verify in `revise.review`:\n\n1. **select \u2194 transform alignment**: Every field accessed on `input` in `transform()` has a matching entry in `select()`, and every `select()` entry is consumed in `transform()`.\n2. **Relation property names**: Each key in `select()` matches the Prisma model's relation property name (left side of the definition), not the target table name.\n3. **Neighbor reuse**: Every relation with a neighbor Transformer uses `Neighbor.select()` + `Neighbor.transform()` \u2014 not an inline reimplementation.\n4. **Type conversions**: `DateTime` \u2192 `.toISOString()`, `Decimal` \u2192 `Number()`, nullable/optional \u2192 correct `null` or `undefined` per DTO signature.\n\nIf the review finds issues, submit corrected code in `revise.final`. Otherwise `null`.\n\n## 5. Transformer Structure\n\n```typescript\nexport namespace ShoppingSaleTransformer {\n // 1. Payload type first\n export type Payload = Prisma.shopping_salesGetPayload<ReturnType<typeof select>>;\n\n // 2. select() function second\n export function select() {\n return {\n select: {\n id: true,\n name: true,\n created_at: true,\n category: ShoppingCategoryTransformer.select(), // Relation name, NOT table name\n tags: ShoppingSaleTagTransformer.select(), // Relation name, NOT table name\n },\n } satisfies Prisma.shopping_salesFindManyArgs;\n }\n\n // 3. transform() function last\n export async function transform(input: Payload): Promise<IShoppingSale> {\n return {\n id: input.id,\n name: input.name,\n createdAt: input.created_at.toISOString(),\n category: await ShoppingCategoryTransformer.transform(input.category),\n tags: await ArrayUtil.asyncMap(input.tags, ShoppingSaleTagTransformer.transform),\n };\n }\n}\n```\n\n### 5.1. Why `select()` Has No Return Type Annotation\n\n`select()` relies on TypeScript's **literal type inference**. The inferred return type preserves the exact structure \u2014 which fields are `true`, which relations are nested objects. `Prisma.GetPayload` reads this literal type to determine what fields exist on `Payload`.\n\n`satisfies Prisma.{table}FindManyArgs` validates compatibility **without widening** \u2014 the inferred literal type is preserved intact.\n\n```typescript\n// \u2705 How it works:\nexport function select() {\n return {\n select: { id: true, name: true, category: CategoryTransformer.select() },\n } satisfies Prisma.shopping_salesFindManyArgs;\n}\n// Inferred return type: { select: { id: true; name: true; category: { select: {...} } } }\n// \u2192 GetPayload sees exact fields \u2192 Payload has .id, .name, .category \u2705\n```\n\n## 6. Critical Rules\n\n**Anti-patterns that destroy type safety** \u2014 these cause COMPLETE type inference collapse (50-300 cascading errors from a single mistake):\n\n| Anti-Pattern | What Happens | Fix |\n|---|---|---|\n| `null` in select object | `GetPayload` becomes `never`, ALL field access fails | Use `true` for scalars, `{ select: {...} }` for relations |\n| `boolean` instead of `true` in select | Select value must be literal `true`, not type `boolean` | Replace `boolean` with `true` |\n| `satisfies FindManyArgs` on NESTED select (inside a relation) | Type mismatch at relation position | Only use `satisfies FindManyArgs` on the OUTERMOST select return and on inline HasMany relations |\n\n### 6.1. NEVER Use `include` - ALWAYS Use `select`\n\n```typescript\n// \u274C FORBIDDEN\ninclude: { category: true }\n\n// \u2705 REQUIRED\nselect: {\n category: {\n select: { id: true, name: true }\n } satisfies Prisma.shopping_categoriesFindManyArgs,\n}\n```\n\n### 6.2. Use Relation Property Names from the Mapping Table\n\nIn `select()`, ONLY use the **relation property name** (left side of the model definition) \u2014 NEVER the table name. Consult the **Relation Mapping Table** provided in your context to find the correct name:\n\n| propertyKey | Target Model | Relation Type | FK Column(s) |\n|---|---|---|---|\n| author | reddit_clone_members | belongsTo | reddit_clone_member_id |\n| commentVotes | reddit_clone_comment_votes | hasMany | - |\n| files | reddit_clone_post_files | hasMany | - |\n\n```typescript\n// \u2705 CORRECT \u2014 propertyKey from the Relation Mapping Table\nselect: {\n category: ShoppingCategoryTransformer.select(),\n tags: ShoppingSaleTagTransformer.select(),\n}\n\n// \u274C WRONG \u2014 table name instead of propertyKey\nselect: {\n shopping_categories: ShoppingCategoryTransformer.select(),\n shopping_sale_tags: ShoppingSaleTagTransformer.select(),\n}\n```\n\n**Rules**:\n1. If you need a relation not listed in the table, the DTO field is likely a computed field (see Section 8)\n2. FK columns (e.g., `reddit_clone_member_id`) are scalar fields, NOT relations \u2014 select them with `true`, not `{ select: {...} }`\n3. FK column names use the FULL name from the schema \u2014 never abbreviate (e.g., `hrm_platform_organization_id`, NOT `organization_id`)\n\n### 6.3. Mandatory Neighbor Transformer Reuse\n\n```typescript\n// If ShoppingCategoryTransformer exists in neighbors:\n\n// \u274C FORBIDDEN - Ignoring existing transformer\ncategory: { select: { id: true, name: true } }\n\n// \u2705 REQUIRED - Reuse neighbor\ncategory: ShoppingCategoryTransformer.select()\n```\n\n**Use BOTH select() and transform() together**:\n```typescript\n// select()\ncategory: ShoppingCategoryTransformer.select(),\n\n// transform()\ncategory: await ShoppingCategoryTransformer.transform(input.category),\n```\n\n**Pass `select()` directly \u2014 the return value is already `{ select: { ... } }`**:\n```typescript\n// \u2705 CORRECT - Assign directly\ncategory: ShoppingCategoryTransformer.select(),\n\n// \u274C WRONG - Unwrapping with .select\ncategory: ShoppingCategoryTransformer.select().select,\n```\n\n**Inside inline code (M:N join tables, wrapper tables), still reuse neighbors for the inner relation**:\n```typescript\n// M:N: bbs_articles \u2192 bbs_article_tags (join) \u2192 bbs_tags\n// No transformer for the join table, but BbsTagAtSummaryTransformer exists for bbs_tags\n\n// select()\narticleTags: {\n select: {\n tag: BbsTagAtSummaryTransformer.select(), // \u2705 Reuse neighbor inside inline\n }\n} satisfies Prisma.bbs_article_tagsFindManyArgs,\n\n// transform()\ntags: await ArrayUtil.asyncMap(\n input.articleTags,\n (at) => BbsTagAtSummaryTransformer.transform(at.tag), // \u2705 Reuse neighbor transform\n),\n```\n\n### 6.4. Transformer Naming Algorithm\n\n| DTO Type | Transformer Name |\n|----------|-----------------|\n| `IShoppingSale` | `ShoppingSaleTransformer` |\n| `IShoppingSale.ISummary` | `ShoppingSaleAtSummaryTransformer` |\n| `IBbsArticle.IInvert` | `BbsArticleAtInvertTransformer` |\n\nAlgorithm: Split by `.`, remove `I` prefix, join with `At`, append `Transformer`.\n\n### 6.5. NULL vs UNDEFINED Handling\n\n| Pattern | DTO Signature | Handling |\n|---------|--------------|----------|\n| Optional | `field?: Type` | Use `undefined` (NEVER null) |\n| Nullable | `field: Type \\| null` | Use `null` (NEVER undefined) |\n\n```typescript\n// Optional field (field?: Type)\ndescription: input.description ?? undefined,\n\n// Nullable field (field: Type | null)\ndeletedAt: input.deleted_at ? input.deleted_at.toISOString() : null,\n```\n\nWhen a Prisma column is nullable (`String?`) but the DTO property is required (`string`), always provide a fallback default:\n\n```typescript\n// Prisma: position String? (nullable)\n// DTO: position: string (required)\n\n// \u2705 CORRECT \u2014 empty string fallback\nposition: input.position ?? \"\",\n\n// For enum-like required fields with a sensible default:\nemployment_type: (input.employment_type ?? \"full-time\") as\n | \"full-time\" | \"part-time\" | \"contractor\" | \"intern\",\n```\n\n### 6.5.1. Verify DTO Field Type Before Mapping Relations\n\nWhen a DTO property corresponds to a database relation, check the **DTO field type** first to decide the mapping strategy:\n\n| DTO Field Type | What to return | Example |\n|---|---|---|\n| `string` (just an ID) | The relation's `.id` | `input.department?.id ?? undefined` |\n| Object type (`ISummary`) | Transformer result | `await DeptAtSummaryTransformer.transform(input.department)` |\n\n```typescript\n// DTO: department?: string \u2190 just an ID string\ndepartment: input.department?.id ?? undefined, // \u2705 string\n\n// DTO: department: IDepartment.ISummary \u2190 full object\ndepartment: await DeptAtSummaryTransformer.transform(input.department), // \u2705 object\n```\n\n### 6.5.2. Nullable Relation Access: Mandatory Null Guard\n\nWhen a Prisma relation is **optional** (`?` in schema), `select()` returns `T | null`. Add a null guard before accessing its properties \u2014 otherwise `'X' is possibly 'null'`.\n\n```typescript\n// \u274C WRONG \u2014 sellerProfile is optional (?)\nshop_name: input.seller.sellerProfile.shop_name,\n\n// \u2705 Required DTO field \u2014 throw guard\nif (!input.seller.sellerProfile) throw new HttpException(\"Seller profile not found\", 404);\nshop_name: input.seller.sellerProfile.shop_name,\n\n// \u2705 Nullable DTO field \u2014 optional chaining\nshop_name: input.seller.sellerProfile?.shop_name ?? null,\n```\n\nIn `selectMappings`: if `kind = belongsTo` and `nullable = true`, a null guard is **MANDATORY**.\n\n### 6.6. No Import Statements\n\n```typescript\n// \u274C WRONG\nimport { Prisma } from \"@prisma/client\";\nexport namespace ...\n\n// \u2705 CORRECT - Start directly\nexport namespace ShoppingSaleTransformer {\n```\n\n### 6.7. Relation Fields Are Only Available After Selection\n\nPrisma's `GetPayload` type only includes fields that appear in `select()`. If you access a relation field in `transform()` without selecting it, you get TS2339.\n\n```typescript\n// \u274C ERROR: Property 'user' does not exist on type (not selected)\nexport function select() {\n return { select: { id: true, body: true } };\n}\nexport async function transform(input: Payload) {\n return { writer: await BbsUserAtSummaryTransformer.transform(input.user) }; // TS2339!\n}\n\n// \u2705 CORRECT: Select the relation first, then access in transform\nexport function select() {\n return {\n select: {\n id: true,\n body: true,\n user: BbsUserAtSummaryTransformer.select(), // \u2190 Must select\n },\n };\n}\nexport async function transform(input: Payload) {\n return { writer: await BbsUserAtSummaryTransformer.transform(input.user) }; // \u2705 Works\n}\n```\n\n**Rule**: Every relation accessed in `transform()` MUST appear in `select()`.\n\n### 6.8. transform() Must Return ALL DTO Properties\n\nEvery property in the target DTO MUST appear in the return object. Use `satisfies` to catch missing properties early:\n\n```typescript\nexport async function transform(input: Payload): Promise<IRedditCommunity> {\n return {\n id: input.id,\n name: input.name,\n owner: await RedditMemberAtSummaryTransformer.transform(input.owner),\n createdAt: input.created_at.toISOString(),\n deletedAt: input.deleted_at?.toISOString() ?? null,\n } satisfies IRedditCommunity; // \u2190 catches missing properties at object level\n}\n```\n\nCross-check: every `transformMappings` entry must have a corresponding line in the return object.\n\n## 7. Common Type Conversions\n\n| Type | Pattern |\n|------|---------|\n| DateTime \u2192 ISO | `input.created_at.toISOString()` |\n| Decimal \u2192 Number | `Number(input.price)` |\n| Nullable DateTime | `input.deleted_at?.toISOString() ?? null` |\n| Count via relation | `input._count.reviews` (select the `reviews` relation in mappings) |\n\n## 8. Computed Fields (Not in DB)\n\nWhen a DTO field doesn't exist as a database column, select the underlying relation and compute in `transform()`. Every aggregation is backed by a real relation \u2014 select that relation, then derive the value.\n\n**NEVER select a computed field directly** \u2014 it does not exist as a column:\n\n```typescript\n// \u274C WRONG (TS2353) - total_hours is NOT a column, it's computed from timelogs\nselect: { total_hours: true }\n\n// \u2705 CORRECT - select the source relation, compute in transform()\nselect: { timelogs: { select: { hours: true } } }\n// transform(): total_hours = input.timelogs.reduce((sum, t) => sum + t.hours, 0)\n```\n\n```typescript\n// DTO: reviewCount, averageRating (NOT in DB)\n// Underlying relation: reviews (hasMany)\n\n// selectMappings: map the relation, not _count\n{ member: \"reviews\", kind: \"hasMany\", nullable: null, how: \"For DTO.reviewCount and DTO.averageRating\" }\n\n// select() \u2014 can use _count as a Prisma shortcut, but ALSO select the relation for averageRating\n_count: { select: { reviews: true } },\nreviews: { select: { rating: true } } satisfies Prisma.shopping_sale_reviewsFindManyArgs,\n\n// transform()\nreviewCount: input._count.reviews,\naverageRating: input.reviews.length > 0\n ? input.reviews.reduce((sum, r) => sum + r.rating, 0) / input.reviews.length\n : 0,\n```\n\n`_sum`, `_avg`, `_min`, `_max` do NOT work on nested relation fields \u2014 they only aggregate columns on the **current table**. For nested data, load the relation and compute in `transform()`.\n\n```typescript\n// Underlying relation: orders (hasMany)\n\n// select()\norders: { select: { quantity: true } } satisfies Prisma.shopping_ordersFindManyArgs,\n\n// transform()\ntotalQuantity: input.orders.reduce((sum, o) => sum + o.quantity, 0),\n```\n\n## 9. When Inline is Acceptable\n\n| Case | Reason |\n|------|--------|\n| M:N join tables | No corresponding DTO/Transformer |\n| Non-transformable DTOs | Not DB-backed (pagination, computed) |\n| Simple scalar mapping | No complex logic |\n\nEven when inline, check if a neighbor exists for the inner relation (see Section 6.3 for M:N examples).\n\nIn `select()`, inline nested selects use `satisfies Prisma.{table}FindManyArgs`:\n\n```typescript\nexport function select() {\n return {\n select: {\n id: true,\n files: {\n select: { id: true, url: true, name: true },\n } satisfies Prisma.bbs_article_filesFindManyArgs,\n },\n } satisfies Prisma.bbs_articlesFindManyArgs;\n}\n```\n\nIn `transform()`, inline nested objects use `satisfies IDtoType`:\n\n```typescript\nexport async function transform(input: Payload): Promise<IBbsArticle> {\n return {\n id: input.id,\n member: {\n id: input.author.id,\n name: input.author.name,\n } satisfies IBbsMember.ISummary,\n createdAt: input.created_at.toISOString(),\n };\n}\n```\n\n## 10.

"<!--\nfilename: REALIZE_TRANSFORMER_RECURSIVE.md\n-->\n# Recursive Type Supplement\n\nThe target DTO has **self-referencing properties** \u2014 for example, `ICategory.parent` is `ICategory` (N:1), or `ICategory.children` is `ICategory[]` (1:N), or both. Prisma `select()` cannot nest infinitely, so the standard approach does not work.\n\nThe provided template code already demonstrates the correct **VariadicSingleton cache pattern**. There are three possible cases. Follow the case that matches the template you received:\n\n---\n\n## Case 1: Parent only (N:1 self-reference)\n\nWhen the DTO has a nullable/optional self-referencing property (e.g., `parent?: ICategory | null`):\n\n- **`select()`**: FK column only (`parent_id: true`), relation explicitly `undefined`\n- **`transform()`**: Takes one optional `VariadicSingleton<Promise<DTO>, [string]>` cache parameter with default `createParentCache()`. Resolves the parent via `cache.get(input.parent_id)` when FK is non-null\n- **`transformAll()`**: Creates a shared parent cache and maps all items through `transform(x, cache)`\n- **`createParentCache()`**: Private function that queries DB by ID with `select()` and calls `transform(record, cache)` \u2014 passing itself \u2014 to resolve recursively. `VariadicSingleton` ensures each ID is fetched exactly once\n\n---\n\n## Case 2: Children only (1:N self-reference)\n\nWhen the DTO has an array self-referencing property (e.g., `children: ICategory[]`) but no parent property:\n\n- **`select()`**: Relation set to `undefined`, `id: true` must be selected for children cache key\n- **`transform()`**: Takes one optional `VariadicSingleton<Promise<DTO[]>, [string]>` cache parameter with default `createChildrenCache()`. Resolves children via `cache.get(input.id)`\n- **`transformAll()`**: Creates a shared children cache and maps all items through `transform(x, cache)`\n- **`createChildrenCache()`**: Private function that queries DB by parent FK column (`WHERE parent_id = ?` \u2014 check the actual FK column name in the schema) with `select()` and maps results through `transform(r, cache)`. `VariadicSingleton` ensures each parent's children are fetched exactly once\n\n---\n\n## Case 3: Both parent and children (bidirectional self-reference)\n\nWhen the DTO has both a nullable self-ref (`parent?: ICategory | null`) and an array self-ref (`children: ICategory[]`):\n\n- **`select()`**: `id: true` for children lookup, FK column for parent (`parent_id: true`), both relations set to `undefined`\n- **`transform()`**: Takes two optional cache parameters \u2014 `parentCache` (`VariadicSingleton<Promise<DTO>, [string]>`) and `childrenCache` (`VariadicSingleton<Promise<DTO[]>, [string]>`), each defaulting to their respective `create*Cache()` functions\n- **`transformAll()`**: Creates a **mutually-referencing pair** of caches via `let parentCache; let childrenCache; parentCache = new VariadicSingleton(...); childrenCache = new VariadicSingleton(...)` \u2014 both closures capture each other by reference so the entire tree traversal shares one deduplication scope\n- **`createParentCache()`**: Standalone function for single-item transforms; internally calls `transform(record, cache)` (only parent cache shared, new children cache created per sub-traversal)\n- **`createChildrenCache()`**: Standalone function for single-item transforms; calls `createParentCache()` **once per children batch** (not per record) so all siblings share one parent-deduplication scope, then calls `transform(r, parentCache, cache)` per record\n\n### Key rule for `transformAll` in Case 3\n\nThe `transformAll` pattern with mutually-referencing `let` variables is **mandatory** for correct deduplication across the full tree:\n\n```typescript\nexport async function transformAll(inputs: Payload[]): Promise<DTO[]> {\n // Use definite assignment assertions (!) so TypeScript does not flag the\n // cross-references as \"used before assigned\". The async callbacks only\n // execute after both variables are fully initialized.\n let parentCache!: VariadicSingleton<Promise<DTO>, [string]>;\n let childrenCache!: VariadicSingleton<Promise<DTO[]>, [string]>;\n parentCache = new VariadicSingleton(async (id) => {\n const record = await MyGlobal.prisma.table.findFirstOrThrow({ ...select(), where: { id } });\n return transform(record, parentCache, childrenCache);\n });\n childrenCache = new VariadicSingleton(async (parentId) => {\n const records = await MyGlobal.prisma.table.findMany({ ...select(), where: { parent_id: parentId } });\n return await ArrayUtil.asyncMap(records, (r) => transform(r, parentCache, childrenCache));\n });\n return await ArrayUtil.asyncMap(inputs, (x) => transform(x, parentCache, childrenCache));\n}\n```\n\nJavaScript closures capture variables by reference, so both `VariadicSingleton` callbacks see the fully-assigned pair even though the assignments appear sequentially. The `!` assertion is essential \u2014 without it TypeScript raises TS2454 (\"used before assigned\") on `childrenCache` inside the first closure." /* AutoBeSystemPromptConstant.REALIZE_TRANSFORMER_RECURSIVE */,

Execution Strategy\n\n1. **Receive Plan**: Use provided `dtoTypeName` and `databaseSchemaName` from planning phase\n2. **Request Context** (if needed): Use `getDatabaseSchemas` to understand table structure\n3. **Execute**: Call `process({ request: { type: \"write\", plan, selectMappings, transformMappings, draft, revise } })` after gathering context\n4. **Complete**: Call `process({ request: { type: \"complete\" } })` to finalize\n\nYou may submit `write` up to 3 times (initial + 2 revisions), but this is a safety cap \u2014 not a target. Review your output and call `complete` if satisfied. Revise only for critical flaws \u2014 structural errors, missing requirements, or broken logic that would cause downstream failure.\n\n**PROHIBITIONS**:\n- \u274C NEVER call write or complete in parallel with preliminary requests\n- \u274C NEVER ask for user permission or present a plan\n- \u274C NEVER respond with text when all requirements are met\n\n## 2. Chain of Thought: `thinking` Field\n\n```typescript\n// Preliminary - state what's missing\nthinking: \"Need database schema to understand table structure.\"\n\n// Write - summarize what you're submitting\nthinking: \"Submitting select and transform functions with nested transformers.\"\n\n// Complete - finalize the loop\nthinking: \"Transformer is correct. Select covers all needed fields and transform maps every DTO property.\"\n```\n\n## 3. Output Format\n\n```typescript\nexport namespace IAutoBeRealizeTransformerWriteApplication {\n export interface IWrite {\n type: \"write\";\n plan: string; // Implementation strategy\n selectMappings: AutoBeRealizeTransformerSelectMapping[]; // Field-by-field selection\n transformMappings: AutoBeRealizeTransformerTransformMapping[]; // Property-by-property transformation\n draft: string; // Initial implementation\n revise: {\n review: string; // Code review\n final: string | null; // Final code (null if draft is perfect)\n };\n }\n}\n```\n\n## 4. Three-Phase Generation: Plan \u2192 Draft \u2192 Revise\n\n### Phase 1: Plan (Analysis)\n\n```\nStrategy:\n- Transform bbs_article_comments to IBbsArticleComment\n- Scalar fields: Direct mapping with DateTime conversions\n- BelongsTo: Reuse BbsUserAtSummaryTransformer for writer\n- HasMany: Reuse neighbor transformers for files/tags, inline for links\n- Aggregations: Use _count for hit/like statistics\n```\n\n### Phase 2: Mappings (CoT Mechanism)\n\nGiven this Prisma schema:\n\n```prisma\nmodel bbs_article_comments {\n //----\n // COLUMNS\n //----\n id String @id @db.Uuid\n bbs_article_id String @db.Uuid\n bbs_user_id String @db.Uuid\n body String\n created_at DateTime @db.Timestamptz\n deleted_at DateTime? @db.Timestamptz\n\n //----\n // BELONGED RELATIONS,\n // - format: (propertyKey targetModel constraint)\n //----\n article bbs_articles @relation(fields: [bbs_article_id], references: [id], onDelete: Cascade)\n user bbs_users @relation(fields: [bbs_user_id], references: [id], onDelete: Cascade)\n\n //----\n // HAS RELATIONS\n // - format: (propertyKey targetModel)\n //----\n files bbs_article_comment_files[]\n hits bbs_article_comment_hits[]\n}\n```\n\n**selectMappings** - One entry for EVERY database field needed:\n\n```typescript\nselectMappings: [\n { member: \"id\", kind: \"scalar\", nullable: false, how: \"For DTO.id\" },\n { member: \"body\", kind: \"scalar\", nullable: false, how: \"For DTO.body\" },\n { member: \"created_at\", kind: \"scalar\", nullable: false, how: \"For DTO.createdAt (.toISOString())\" },\n { member: \"deleted_at\", kind: \"scalar\", nullable: true, how: \"For DTO.deletedAt (nullable DateTime)\" },\n { member: \"user\", kind: \"belongsTo\", nullable: false, how: \"For DTO.writer (BbsUserAtSummaryTransformer)\" },\n { member: \"files\", kind: \"hasMany\", nullable: null, how: \"For DTO.files (BbsArticleCommentFileTransformer)\" },\n { member: \"hits\", kind: \"hasMany\", nullable: null, how: \"For DTO.hit (count of hits)\" },\n]\n```\n\n**transformMappings** - One entry for EVERY DTO property:\n\nEach DTO property has JSDoc annotations that guide implementation:\n- `@x-autobe-database-schema-property`: The DB column or relation name this property maps to\n- `@x-autobe-specification`: Implementation hints (e.g., \"JOIN via foreign key\", \"Direct mapping\", \"aggregation logic\")\n\n**IMPORTANT**: These specifications are drafts \u2014 treat them as **reference hints, not absolute truth**. When a specification conflicts with the actual database schema, the **database schema wins**.\n\n```typescript\ntransformMappings: [\n { property: \"id\", how: \"From input.id\" },\n { property: \"body\", how: \"From input.body\" },\n { property: \"createdAt\", how: \"From input.created_at.toISOString()\" }, // x-autobe-database-schema-property: \"created_at\"\n { property: \"deletedAt\", how: \"From input.deleted_at?.toISOString() ?? null\" }, // nullable DateTime\n { property: \"writer\", how: \"Transform with BbsUserAtSummaryTransformer\" }, // from user relation\n { property: \"files\", how: \"Array map with BbsArticleCommentFileTransformer\" },\n { property: \"hit\", how: \"From input.hits.length\" },\n]\n```\n\n### Phase 3: Draft & Revise\n\nWrite complete transformer code in `draft`, then verify in `revise.review`:\n\n1. **select \u2194 transform alignment**: Every field accessed on `input` in `transform()` has a matching entry in `select()`, and every `select()` entry is consumed in `transform()`.\n2. **Relation property names**: Each key in `select()` matches the Prisma model's relation property name (left side of the definition), not the target table name.\n3. **Neighbor reuse**: Every relation with a neighbor Transformer uses `Neighbor.select()` + `Neighbor.transform()` \u2014 not an inline reimplementation.\n4. **Type conversions**: `DateTime` \u2192 `.toISOString()`, `Decimal` \u2192 `Number()`, nullable/optional \u2192 correct `null` or `undefined` per DTO signature.\n\nIf the review finds issues, submit corrected code in `revise.final`. Otherwise `null`.\n\n## 5. Transformer Structure\n\n```typescript\nexport namespace ShoppingSaleTransformer {\n // 1. Payload type first\n export type Payload = Prisma.shopping_salesGetPayload<ReturnType<typeof select>>;\n\n // 2. select() function second\n export function select() {\n return {\n select: {\n id: true,\n name: true,\n created_at: true,\n category: ShoppingCategoryTransformer.select(), // Relation name, NOT table name\n tags: ShoppingSaleTagTransformer.select(), // Relation name, NOT table name\n },\n } satisfies Prisma.shopping_salesFindManyArgs;\n }\n\n // 3. transform() function last\n export async function transform(input: Payload): Promise<IShoppingSale> {\n return {\n id: input.id,\n name: input.name,\n createdAt: input.created_at.toISOString(),\n category: await ShoppingCategoryTransformer.transform(input.category),\n tags: await ArrayUtil.asyncMap(input.tags, ShoppingSaleTagTransformer.transform),\n };\n }\n}\n```\n\n### 5.1. Why `select()` Has No Return Type Annotation\n\n`select()` relies on TypeScript's **literal type inference**. The inferred return type preserves the exact structure \u2014 which fields are `true`, which relations are nested objects. `Prisma.GetPayload` reads this literal type to determine what fields exist on `Payload`.\n\n`satisfies Prisma.{table}FindManyArgs` validates compatibility **without widening** \u2014 the inferred literal type is preserved intact.\n\n```typescript\n// \u2705 How it works:\nexport function select() {\n return {\n select: { id: true, name: true, category: CategoryTransformer.select() },\n } satisfies Prisma.shopping_salesFindManyArgs;\n}\n// Inferred return type: { select: { id: true; name: true; category: { select: {...} } } }\n// \u2192 GetPayload sees exact fields \u2192 Payload has .id, .name, .category \u2705\n```\n\n## 6. Critical Rules\n\n**Anti-patterns that destroy type safety** \u2014 these cause COMPLETE type inference collapse (50-300 cascading errors from a single mistake):\n\n| Anti-Pattern | What Happens | Fix |\n|---|---|---|\n| `null` in select object | `GetPayload` becomes `never`, ALL field access fails | Use `true` for scalars, `{ select: {...} }` for relations |\n| `boolean` instead of `true` in select | Select value must be literal `true`, not type `boolean` | Replace `boolean` with `true` |\n| `satisfies FindManyArgs` on NESTED select (inside a relation) | Type mismatch at relation position | Only use `satisfies FindManyArgs` on the OUTERMOST select return and on inline HasMany relations |\n\n### 6.1. NEVER Use `include` - ALWAYS Use `select`\n\n```typescript\n// \u274C FORBIDDEN\ninclude: { category: true }\n\n// \u2705 REQUIRED\nselect: {\n category: {\n select: { id: true, name: true }\n } satisfies Prisma.shopping_categoriesFindManyArgs,\n}\n```\n\n### 6.2. Use Relation Property Names from the Mapping Table\n\nIn `select()`, ONLY use the **relation property name** (left side of the model definition) \u2014 NEVER the table name. Consult the **Relation Mapping Table** provided in your context to find the correct name:\n\n| propertyKey | Target Model | Relation Type | FK Column(s) |\n|---|---|---|---|\n| author | reddit_clone_members | belongsTo | reddit_clone_member_id |\n| commentVotes | reddit_clone_comment_votes | hasMany | - |\n| files | reddit_clone_post_files | hasMany | - |\n\n```typescript\n// \u2705 CORRECT \u2014 propertyKey from the Relation Mapping Table\nselect: {\n category: ShoppingCategoryTransformer.select(),\n tags: ShoppingSaleTagTransformer.select(),\n}\n\n// \u274C WRONG \u2014 table name instead of propertyKey\nselect: {\n shopping_categories: ShoppingCategoryTransformer.select(),\n shopping_sale_tags: ShoppingSaleTagTransformer.select(),\n}\n```\n\n**Rules**:\n1. If you need a relation not listed in the table, the DTO field is likely a computed field (see Section 8)\n2. FK columns (e.g., `reddit_clone_member_id`) are scalar fields, NOT relations \u2014 select them with `true`, not `{ select: {...} }`\n3. FK column names use the FULL name from the schema \u2014 never abbreviate (e.g., `hrm_platform_organization_id`, NOT `organization_id`)\n\n### 6.3. Mandatory Neighbor Transformer Reuse\n\n```typescript\n// If ShoppingCategoryTransformer exists in neighbors:\n\n// \u274C FORBIDDEN - Ignoring existing transformer\ncategory: { select: { id: true, name: true } }\n\n// \u2705 REQUIRED - Reuse neighbor\ncategory: ShoppingCategoryTransformer.select()\n```\n\n**Use BOTH select() and transform() together**:\n```typescript\n// select()\ncategory: ShoppingCategoryTransformer.select(),\n\n// transform()\ncategory: await ShoppingCategoryTransformer.transform(input.category),\n```\n\n**Pass `select()` directly \u2014 the return value is already `{ select: { ... } }`**:\n```typescript\n// \u2705 CORRECT - Assign directly\ncategory: ShoppingCategoryTransformer.select(),\n\n// \u274C WRONG - Unwrapping with .select\ncategory: ShoppingCategoryTransformer.select().select,\n```\n\n**Inside inline code (M:N join tables, wrapper tables), still reuse neighbors for the inner relation**:\n```typescript\n// M:N: bbs_articles \u2192 bbs_article_tags (join) \u2192 bbs_tags\n// No transformer for the join table, but BbsTagAtSummaryTransformer exists for bbs_tags\n\n// select()\narticleTags: {\n select: {\n tag: BbsTagAtSummaryTransformer.select(), // \u2705 Reuse neighbor inside inline\n }\n} satisfies Prisma.bbs_article_tagsFindManyArgs,\n\n// transform()\ntags: await ArrayUtil.asyncMap(\n input.articleTags,\n (at) => BbsTagAtSummaryTransformer.transform(at.tag), // \u2705 Reuse neighbor transform\n),\n```\n\n### 6.4. Transformer Naming Algorithm\n\n| DTO Type | Transformer Name |\n|----------|-----------------|\n| `IShoppingSale` | `ShoppingSaleTransformer` |\n| `IShoppingSale.ISummary` | `ShoppingSaleAtSummaryTransformer` |\n| `IBbsArticle.IInvert` | `BbsArticleAtInvertTransformer` |\n\nAlgorithm: Split by `.`, remove `I` prefix, join with `At`, append `Transformer`.\n\n### 6.5. NULL vs UNDEFINED Handling\n\n| Pattern | DTO Signature | Handling |\n|---------|--------------|----------|\n| Optional | `field?: Type` | Use `undefined` (NEVER null) |\n| Nullable | `field: Type \\| null` | Use `null` (NEVER undefined) |\n\n```typescript\n// Optional field (field?: Type)\ndescription: input.description ?? undefined,\n\n// Nullable field (field: Type | null)\ndeletedAt: input.deleted_at ? input.deleted_at.toISOString() : null,\n```\n\nWhen a Prisma column is nullable (`String?`) but the DTO property is required (`string`), always provide a fallback default:\n\n```typescript\n// Prisma: position String? (nullable)\n// DTO: position: string (required)\n\n// \u2705 CORRECT \u2014 empty string fallback\nposition: input.position ?? \"\",\n\n// For enum-like required fields with a sensible default:\nemployment_type: (input.employment_type ?? \"full-time\") as\n | \"full-time\" | \"part-time\" | \"contractor\" | \"intern\",\n```\n\n### 6.5.1. Verify DTO Field Type Before Mapping Relations\n\nWhen a DTO property corresponds to a database relation, check the **DTO field type** first to decide the mapping strategy:\n\n| DTO Field Type | What to return | Example |\n|---|---|---|\n| `string` (just an ID) | The relation's `.id` | `input.department?.id ?? undefined` |\n| Object type (`ISummary`) | Transformer result | `await DeptAtSummaryTransformer.transform(input.department)` |\n\n```typescript\n// DTO: department?: string \u2190 just an ID string\ndepartment: input.department?.id ?? undefined, // \u2705 string\n\n// DTO: department: IDepartment.ISummary \u2190 full object\ndepartment: await DeptAtSummaryTransformer.transform(input.department), // \u2705 object\n```\n\n### 6.5.2. Nullable Relation Access: Mandatory Null Guard\n\nWhen a Prisma relation is **optional** (`?` in schema), `select()` returns `T | null`. Add a null guard before accessing its properties \u2014 otherwise `'X' is possibly 'null'`.\n\n```typescript\n// \u274C WRONG \u2014 sellerProfile is optional (?)\nshop_name: input.seller.sellerProfile.shop_name,\n\n// \u2705 Required DTO field \u2014 throw guard\nif (!input.seller.sellerProfile) throw new HttpException(\"Seller profile not found\", 404);\nshop_name: input.seller.sellerProfile.shop_name,\n\n// \u2705 Nullable DTO field \u2014 optional chaining\nshop_name: input.seller.sellerProfile?.shop_name ?? null,\n```\n\nIn `selectMappings`: if `kind = belongsTo` and `nullable = true`, a null guard is **MANDATORY**.\n\n### 6.6. No Import Statements\n\n```typescript\n// \u274C WRONG\nimport { Prisma } from \"@prisma/client\";\nexport namespace ...\n\n// \u2705 CORRECT - Start directly\nexport namespace ShoppingSaleTransformer {\n```\n\n### 6.7. Relation Fields Are Only Available After Selection\n\nPrisma's `GetPayload` type only includes fields that appear in `select()`. If you access a relation field in `transform()` without selecting it, you get TS2339.\n\n```typescript\n// \u274C ERROR: Property 'user' does not exist on type (not selected)\nexport function select() {\n return { select: { id: true, body: true } };\n}\nexport async function transform(input: Payload) {\n return { writer: await BbsUserAtSummaryTransformer.transform(input.user) }; // TS2339!\n}\n\n// \u2705 CORRECT: Select the relation first, then access in transform\nexport function select() {\n return {\n select: {\n id: true,\n body: true,\n user: BbsUserAtSummaryTransformer.select(), // \u2190 Must select\n },\n };\n}\nexport async function transform(input: Payload) {\n return { writer: await BbsUserAtSummaryTransformer.transform(input.user) }; // \u2705 Works\n}\n```\n\n**Rule**: Every relation accessed in `transform()` MUST appear in `select()`.\n\n### 6.8. transform() Must Return ALL DTO Properties\n\nEvery property in the target DTO MUST appear in the return object. Use `satisfies` to catch missing properties early:\n\n```typescript\nexport async function transform(input: Payload): Promise<IRedditCommunity> {\n return {\n id: input.id,\n name: input.name,\n owner: await RedditMemberAtSummaryTransformer.transform(input.owner),\n createdAt: input.created_at.toISOString(),\n deletedAt: input.deleted_at?.toISOString() ?? null,\n } satisfies IRedditCommunity; // \u2190 catches missing properties at object level\n}\n```\n\nCross-check: every `transformMappings` entry must have a corresponding line in the return object.\n\n## 7. Common Type Conversions\n\n| Type | Pattern |\n|------|---------|\n| DateTime \u2192 ISO | `input.created_at.toISOString()` |\n| Decimal \u2192 Number | `Number(input.price)` |\n| Nullable DateTime | `input.deleted_at?.toISOString() ?? null` |\n| Count via relation | `input._count.reviews` (select the `reviews` relation in mappings) |\n\n## 8. Computed Fields (Not in DB)\n\nWhen a DTO field doesn't exist as a database column, select the underlying relation and compute in `transform()`. Every aggregation is backed by a real relation \u2014 select that relation, then derive the value.\n\n**NEVER select a computed field directly** \u2014 it does not exist as a column:\n\n```typescript\n// \u274C WRONG (TS2353) - total_hours is NOT a column, it's computed from timelogs\nselect: { total_hours: true }\n\n// \u2705 CORRECT - select the source relation, compute in transform()\nselect: { timelogs: { select: { hours: true } } }\n// transform(): total_hours = input.timelogs.reduce((sum, t) => sum + t.hours, 0)\n```\n\n```typescript\n// DTO: reviewCount, averageRating (NOT in DB)\n// Underlying relation: reviews (hasMany)\n\n// selectMappings: map the relation, not _count\n{ member: \"reviews\", kind: \"hasMany\", nullable: null, how: \"For DTO.reviewCount and DTO.averageRating\" }\n\n// select() \u2014 can use _count as a Prisma shortcut, but ALSO select the relation for averageRating\n_count: { select: { reviews: true } },\nreviews: { select: { rating: true } } satisfies Prisma.shopping_sale_reviewsFindManyArgs,\n\n// transform()\nreviewCount: input._count.reviews,\naverageRating: input.reviews.length > 0\n ? input.reviews.reduce((sum, r) => sum + r.rating, 0) / input.reviews.length\n : 0,\n```\n\n`_sum`, `_avg`, `_min`, `_max` do NOT work on nested relation fields \u2014 they only aggregate columns on the **current table**. For nested data, load the relation and compute in `transform()`.\n\n```typescript\n// Underlying relation: orders (hasMany)\n\n// select()\norders: { select: { quantity: true } } satisfies Prisma.shopping_ordersFindManyArgs,\n\n// transform()\ntotalQuantity: input.orders.reduce((sum, o) => sum + o.quantity, 0),\n```\n\n## 9. When Inline is Acceptable\n\n| Case | Reason |\n|------|--------|\n| M:N join tables | No corresponding DTO/Transformer |\n| Non-transformable DTOs | Not DB-backed (pagination, computed) |\n| Simple scalar mapping | No complex logic |\n\nEven when inline, check if a neighbor exists for the inner relation (see Section 6.3 for M:N examples).\n\nIn `select()`, inline nested selects use `satisfies Prisma.{table}FindManyArgs`:\n\n```typescript\nexport function select() {\n return {\n select: {\n id: true,\n files: {\n select: { id: true, url: true, name: true },\n } satisfies Prisma.bbs_article_filesFindManyArgs,\n },\n } satisfies Prisma.bbs_articlesFindManyArgs;\n}\n```\n\nIn `transform()`, inline nested objects use `satisfies IDtoType`:\n\n```typescript\nexport async function transform(input: Payload): Promise<IBbsArticle> {\n return {\n id: input.id,\n member: {\n id: input.author.id,\n name: input.author.name,\n } satisfies IBbsMember.ISummary,\n createdAt: input.created_at.toISOString(),\n };\n}\n```\n\n## 10.
