chore(rebar): Pier_T_rebar 작업 폴더 초기 구성 및 외부 의존 파일 통합

- Code\rebar_pipeline, review_pipeline, pier-program을 정션에서 실제 폴더로 전환 - Code\rhino_mcp 및 CLAUDE_rhino배경.md 추가, .mcp.json은 PYTHONPATH로 새 위치 사용 - pier-program 내부 .git 제거(이력은 backup\pier-program_20261028.bundle에 보관) - worktree 가이드 반영(CLAUDE.local.md, HANDOFF.md) - D:\Rhino-MCP 경로 참조를 새 위치로 치환 Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

+## MCP Table Management Tools
+
+| Tool | Purpose | Scope |
+|------|---------|-------|
+| `backend_table_create` | Create table | table:create |
+| `backend_table_list` | List tables | table:read |
+| `backend_table_get` | Get table detail + schema | table:read |
+| `backend_table_delete` | Delete table | table:delete |
+| `backend_field_manage` | Add/modify/delete fields | table:update |
+| `backend_index_manage` | Manage indexes | table:update |
+| `backend_schema_version_list` | Schema version history | table:read |
+| `backend_schema_version_get` | Schema version detail | table:read |
+| `backend_schema_version_apply` | Apply schema version (rollback) | table:update |
+| `backend_index_version_list` | Index version history | table:read |
+| `backend_index_version_get` | Index version detail | table:read |
+
+## MCP Data CRUD Tools
+
+| Tool | Purpose | Key Parameters |
+|------|---------|----------------|
+| `backend_data_list` | List records (filter, sort, paginate) | tableId, page?, limit?, sortBy?, sortDirection?, andFilters?, orFilters? |
+| `backend_data_get` | Get single record | tableId, recordId |
+| `backend_data_create` | Create record | tableId, data: { field: value } |
+| `backend_data_update` | Partial update record | tableId, recordId, data: { field: value } |
+| `backend_data_delete` | Delete record | tableId, recordId |
+
+All Data CRUD tools require: organizationId, projectId, environmentId (from `get_context`).
+
+### Filter Operators
+
+| Operator | Meaning | Example |
+|----------|---------|---------|
+| `$eq` | Equal | `{ "status": { "$eq": "active" } }` |

+| `$gt` / `$gte` | Greater than / >= | `{ "age": { "$gt": 18 } }` |
+| `$lt` / `$lte` | Less than / <= | `{ "price": { "$lt": 100 } }` |
+| `$in` / `$nin` | In / Not in array | `{ "tag": { "$in": ["a","b"] } }` |
+
+## MCP Guide Docs (via search_docs)
+
+Use `search_docs` tool to access these guides:
+
+| Doc ID | Content |
+|--------|---------|
+| `4_howto_implement_data_crud` | CRUD implementation patterns |
+| `7_code_examples_data` | CRUD + file upload code examples |
+
+Use `get_operation_schema` to get any tool's input/output schema.
+
+## REST Data API
+
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| GET | /v1/data/{table} | List (filter, sort, page, limit) |
+| POST | /v1/data/{table} | Create |
+| GET | /v1/data/{table}/{id} | Get single |
+| PATCH | /v1/data/{table}/{id} | Partial update |
+| DELETE | /v1/data/{table}/{id} | Delete |
+
+## Filtering
+
+- Text search: `?search=keyword`
+- AND filter: `?filter[field1]=value1&filter[field2]=value2`
+- Comparison operators: `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, `$nin`
+- Sort: `?sort=field:asc` (or desc)
+- Pagination: `?page=1&limit=20` (default 20, max 100)
+
+## Relations & Joins
+
+- Configure table relationships
+- Join queries for related data retrieval
+
+## Index Management
+
+- Single/compound index creation
+- Manage via MCP `backend_index_manage`
+- Essential for query performance optimization
