1. Unified Image Simulator for LSE
This PR introduces a unified simulator that consolidates:
Description:
A single simulator that supports three modes:
2. Temporary Tiled Ingestor
A temporary tiled ingestor is added for ingesting the 733 dataset, enabling testing of the LSE live mode.
This component will later be moved to a dedicated Tiled ingestor repository.
Besides, we want to develop a unified Tiled ingestor to load original images—such as SMI data (fetched from the NSLS-II Tiled server using given URLs saved in .db files) or 733 data (loaded from the local file system)—into a local Tiled server. This will enable us to run the unified simulator without requiring access to remote Tiled instances.
When ingesting data, we should aim to mimic the Tiled URL structure. For example, at NSLS-II, SMI data URLs typically look like the following:

into the container.
However, I’m not yet sure what the corresponding URL format looks like for the ALS 733 experiment.
3. XPS Websocket Simulator
We read TRS data from the local file system and send it via WebSocket to mimic the XPS Arroyo WebSocket implementation: link.
