Build the application

## Build
Inspect optical weld scanner logs to evaluate weld bead porosity and undercuts against ISO 5817 criteria. Route non-conforming weld seams into localized rework queues and formulate verification evidence dossiers.

## User
Welding Quality Inspector

## Workflow
1. Ingest 3D weld bead profile scan records containing seam width, depth, and porosity voids.
2. Evaluate profiles against ISO 5817 weld quality grade acceptance levels.
3. Queue non-conforming weld segments into localized gouge-and-re-weld work orders.
4. Synthesize an evidence dossier cross-referencing operator IDs and weld wire batch lots.

## Interface
Weld seam defect viewer with 3D profile overlays and rework queue assignment buttons.

## Data
Synthesize JSON records representing normalized 3D weld seam profile measurements and defect classes.
Starter examples below are synthetic. They are not downloaded records.

## Source
[MoveIt robotics](https://raw.githubusercontent.com/moveit/moveit2/main/README.md)
Applies MoveIt geometric shapes and bounding collision volume conventions from Source 1 to weld inspection regions.

## Tools
langgraph, fastapi, pandas.
LangGraph manages stateful transitions between defect detection, rework routing, and final inspector sign-off.
Local or cloud LLM to generate clear welding engineer rework instructions and evidence summaries.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Correctly identifies weld seams violating ISO 5817 quality grade B limits.
- Generates localized grinding and re-welding path coordinates for operators.
- Produces complete defect evidence review dossiers for QA archiving.

## Safety
Read-only inspection and rework queue planner; does not alter welding equipment parameters.
Use mock external writes. Require human review before any real deployment.
