I think rewriting KrBot is right idea. The bot has one significant limitation: it generates report periodically. As the reports user I want to see updated report immediately after fixing several items.

Also it does not process "baserevid" parameter and does not return entity->lastrevid value.

Ivan_A_Krestinin added a comment to T189747: Toolforge node for constraint reports updating bot.

Bot parses full Wikidata dump (844 GB of XML files) and load items and its properties into memory. This in memory data is used for reports generation. Now Wikidata has ~47000000 items. So my code uses ~144 bytes per item. I can not load only part of data because dumps parsing is long and sequential process (~5 hours, 4 threads are used).

Ivan_A_Krestinin added a comment to T168532: Check constraints on qualifiers and references.

About KrBot: current implementation fully ignores references and ranks. Qualifiers are checked only by https://www.wikidata.org/wiki/Q37845003 and https://www.wikidata.org/wiki/Q21510863. Also https://www.wikidata.org/wiki/Q19474404 constraint uses qualifiers if https://www.wikidata.org/wiki/Property:P4155 is specified. In other words: qualifiers are not checked too.

Ivan_A_Krestinin added a comment to T141859: [Task] Contemporary constraint check.

All other constraints store settings as qualifiers on property page. I think it is good practice make all constraints as similar as possible. This makes implementation and understanding of full constraints system easier.

The most constraints are fully parametrized. Algorithms do not have constantly defined properties. The only exception is P31/P279 in Type/Value type constraints. Some users think that P31/P279 must be parameters too. The second thing is OR aggregation. This makes the algorithm indeterministic a bit.
