Graph-of-Thought-Saliency-Ranking

The problem

When exploring complex ideas, it is difficult to keep track of which paths are actually productive and which are just going in circles. It's hard to manually filter out irrelevant information while trying to solve a hard problem.

What it does

It maps out different ideas as a branching web and scores each path based on how much useful information it contains. It then automatically ignores the paths that don't lead to meaningful results.

Why it matters

It allows for exploring complex problems by automatically filtering out dead ends and focusing only on the most relevant paths.

Validation

It was run in the sandbox and it failed. run output shows an error/traceback — the artifact does NOT run clean.

No screenshot — there is nothing working to show. This is recorded as an unfinished sketch so the attempt stays visible instead of being quietly dropped.

The code

All of it — 70 lines, one file, standard library only.
