Downgrade jqwik to 1.9.3 and document QuickTheories replacement plan#83
Merged
Conversation
Avoid the anti-AI prompt-injection string added in jqwik 1.10.0 (and the 1.10.1 release note declaring the library is not meant to be used by AI coding agents). The 1.9.x line is the last release without that behaviour. Long-term plan tracked in CLAUDE.md is to replace jqwik entirely with junit-quickcheck or hand-rolled JUnit Jupiter @ParameterizedTest.
Prevent future bumps to jqwik >= 1.10.0, which ships an anti-AI prompt-injection string in test stdout. See CLAUDE.md for context; replacement with QuickTheories is tracked as an urgent TODO.

jqwik 1.10.0+ deliberately injects a prompt-injection string into test stdout targeting AI coding agents. This is incompatible with the AI-assisted workflow this project uses. Rather than upgrade to a hostile upstream, we downgrade to the last safe version (1.9.3) as an interim measure while planning the migration to QuickTheories, which offers:
