Key Technical Notes
- Jackson 3: Spring 7 defaults to
JacksonJsonHttpMessageConverter (Jackson 3); hook added to HttpMessageConverterInstrumentation
- javax → jakarta: Already handled by existing [6,) modules — no migration needed
- Muzzle ranges: All existing
[6,) modules cover Spring Framework 7 without new sibling modules
- Groovy migration: CLAUDE.md requires any edited Groovy test → full JUnit5 Java migration; webmvc/security/webflux fixtures need migration before PRs
- Sample app: 39 spans verified on Boot 4.0.0-RC2 end-to-end
Oracle / Toolkit Notes
- Oracle assessor fixes applied: timeout 1→5min, max_turns 40→60, "read latest plan only" prompt
version_bump lane added to oracle to skip behavior_verified gate for dep-bump tasks- Stale
.pyc with merge conflict markers cleared (was blocking oracle)
