Spring Context DI Reasoning

Source mapping: Tier 1 critical skill derived from Kotlin_Spring_Developer_Pipeline.md (SK-02).

Mission

Reconstruct why the Spring container made a specific decision and propose the narrowest fix that restores correct wiring. Assume the visible exception is often a wrapper, not the real cause.

Collect Evidence First

• Read the full exception chain, not only the top exception.
• Read the startup log lines around the first failure and around any Caused by: entries.
• Read the relevant @Configuration, component classes, @Bean methods, @ConfigurationProperties, and active profiles.
• Read the build context if it is not already known. Reuse output from project-context-ingestion when available.
• If a condition evaluation report or auto-configuration report exists, use it.
