A Spring Boot 4.1.1 order service started 12 ways (plain and extracted jar, Spring AOT output, AppCDS, AOT cache trained with and without traffic, JDK 27, native image), ten interleaved rounds each, with first-request latency; 24 cache-mismatch cases; Docker layer arithmetic. Transcripts are in output/ (no docs/ folder). Co-Authored-By: Claude Sonnet 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01TF9JWFvJSNm6HVzswzZU5a
