Side B fixes a real performance/correctness problem in the sorterc scan (avoiding full log replay with centrality computation), adds richer error reporting (full parse_error text), a genuinely useful --ingest replay-and-compile feature, updates docs to match, and includes new tests validating the fix. Side A adds a sizable new speculative subsystem (form templating with $form holes, a unified /ui endpoint) that duplicates existing routes' functionality and even flags its own security caveat, with the commit message itself just 'progress', making it feel more exploratory than a finished, load-bearing improvement.
