Couple of nits on tests and such, but otherwise looks about ready to go on my end! Thanks for all thorough clean-up effort!!

Couple of small nits in the test suite, but nothing that I'm willing to hold this PR up over (I've already held it up to long lol 😅)

Quick sanity check here: This is creating a new type Entity equivalent to
class Entity:
name = "sample" # <- Note: this is a class level var
path = str(entity_path) # <- ditto here
entity = Entity # <- `entity` is now an alias for the _type_ `Entity`so isintance(entity, type) == True and isinstance(e(), object) == True != isinstance(e(), type)
is this intended or did you mean something like this:
@dataclasses.dataclass # <- decorator to make class level vars instance vars
class Entity:
name: str = "sample"
path: str = str(entity_path)
entity = Entity() # <- `entity` now an instance of `Entity`? Technically this doesn't really matter as we only expect one instance of this class, but I'm not gonna give you a review without being overly pedantic 😅

Minor nit: Should this be using the test_dir fixture just so that artifacts are left over in the event of a failure for manual inspection?

Minor nit: If there is no shared stand-up/tear-down logic in this test class, can we make all of these tests top level functions, just to match the style of the rest of the test suite?

If this model.exisits() condition is not met, I would argue that something has gone wrong. Thoughts on changing it to an assert instead?

Similar argument here, if the run_dirs is empty, I argue the test failed. Thoughts on making this an assert as well?
assert len(run_dirs) == 1, "Incorrect number of run dirs created"

Not you're change, but this must have gotten past a different review. In theory entity.type should always return a str, meaning this block is unreachable. Do you think this should read
if entity.type == "Ensemble":
...or
if isinstance(entity, Ensemble):
...instead??

Overview
This PR removes telemetry collection, SmartDashboard functionality, and indirect entrypoint capabilities from SmartSim. Additionally, it significantly improves the codebase's maintainability by centralizing directory path management through the CONFIG system and eliminating hardcoded
.smartsimdirectory references throughout the codebase.Changes Made
🗑️ Removed Features
🏗️ Configuration System Improvements
.smartsimdirectory references with CONFIG properties📁 New CONFIG Properties
📂 Directory Structure
The new hierarchical structure provides better organization:

🏗️ Enhanced Modularity
Technical Details
CONFIG System Architecture
The new CONFIG properties follow a hierarchical dependency model:
smartsim_base_diris the foundation (.smartsim)dragon_default_subdirbuilds on base ({base}/dragon)dragon_logs_subdirbuilds on dragon ({dragon}/logs)metadata_subdirbuilds on base ({base}/metadata)This ensures that changing the base directory automatically propagates to all subdirectories, and changing the dragon directory affects the dragon logs directory.
Path Management Implementation
All directory references now use f-string formatting with CONFIG properties:
