Core Features
∑
Signature-based dedup
Computes output tuple across all probes. Rules with identical signatures are functionally equivalent and removed.
⌗
Built-in 30-word probe set
Covers short/long words, mixed-case, digits, specials, repeated chars. No external wordlist needed.
+
Extensible probes
Add words via --extra-probes or sample from a wordlist with --probe-file.
Processing Workflow
Step 1
Assemble probe set
Built-in words + extra-probes + sampled from probe-file, deduplicated.
Step 2
Apply rules
Pure-Python interpreter applies each rule to every probe word.
Step 3
Compute signatures
Collect all transformed outputs into a tuple per rule.
Step 4
Deduplicate
Dict maps signature → first rule seen. Duplicates discarded, order preserved.

About This Project
This entire project — rulest, concentrator, and all the tooling around it — was built
purely as a hobby and learning exercise. There was no grand plan, just
curiosity about whether frequency analysis on debug output could produce better rules
than manual curation or purely random generation. Turns out: yes, noticeably so.
If you find the tools or the methodology useful, great. If you have ideas for improvement,
the repos are open. And if you just enjoy poking at this kind of thing for the same
reason — have fun.
