# TASK-106: Modeling Transform RPC Result Alignment

**Priority:** 🟡 Medium  
**Category:** MCP / Addon Runtime Alignment  
**Estimated Effort:** Small  
**Dependencies:** None  
**Status:** ✅ Done

**Completion Summary:** Fixed the RPC result mismatch for `modeling_transform_object`. The Blender addon returns a structured object payload for `modeling.transform_object`, and the server-side `ModelingToolHandler` now consumes that structured payload instead of incorrectly expecting a plain string result.

---

## Objective

Keep the server-side modeling handler aligned with the actual addon RPC contract for object transforms.

---

## Problem

`modeling.transform_object` returned a dict payload from the addon, but the server-side handler enforced `require_str_result(...)`.

This caused runtime failures like:

- `Blender Error: Expected string result, got dict`

even though the addon operation itself succeeded.

---

## Solution

Treat `modeling.transform_object` as a structured RPC result on the server side and keep the user-facing MCP string response derived from that successful structured payload.

---

## Repository Touchpoints

- `server/application/tool_handlers/modeling_handler.py`
- `tests/unit/tools/modeling/test_modeling_handler_rpc.py`

---

## Acceptance Criteria

- `modeling_transform_object` no longer fails on successful dict payloads
- the server-side modeling handler stays aligned with the addon RPC contract
- regression coverage exists for the exact payload shape returned by the addon
