Based on my analysis of the HVM3 codebase you provided, here are the potential weak points and bugs that could cause issues:
The code extensively uses unsafeInterleaveIO in functions like collapseDupsAtLazy and extractCoreAtLazy. This creates thunks with non-deterministic evaluation order, which can lead to:
Based on the code you shared and the HVM3 codebase I've reviewed, I can explain why you're seeing four universes instead of two when the program collapses.
Looking at the HVML.Collapse module, the issue is related to how HVM3 handles superpositions (represented with the & notation in the code). The collapseDupsAt and collapseSups functions create a tree structure that represents all possible combinations of choices.
The key is in how the code processes nested superpositions. In your example:
| Solution Indexer Project Requirements | |
| Project Overview | |
| Develop a high-performance C# command-line tool that indexes a .NET solution folder, analyzes its structure and dependencies, and generates a comprehensive prompt containing relevant information. The tool should scan project files, source code, and configuration files with minimal memory usage and maximum performance. | |
| Core Requirements | |
| Input & Output | |
| Accept a directory path as the main command-line argument | |
| Optional parameter for output file path (default: "solution-prompt.txt") | |
| Support a --recursive flag for deep directory traversal | |
| Generate a well-formatted Markdown document describing the solution |
| /****** Object: Table [dbo].[AttributeFilters] Script Date: 3/18/2022 11:17:20 AM ******/ | |

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).
Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:
Rx.Observable.prototype.flatMapLatest(selector, [thisArg])
Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.

| // Create the keypair | |
| $res=openssl_pkey_new(); | |
| // Get private key | |
| openssl_pkey_export($res, $privatekey); | |
| // Get public key | |
| $publickey=openssl_pkey_get_details($res); |
