AI Core Update: Goals, Tracing, and Stability

Several changes focused on enhancing meta-harness diagnostics and AI reasoning stability

Several changes focused on enhancing meta-harness diagnostics and AI reasoning stability. Prompt tracing was added for the meta-harness by introducing the CHALIE_LOG_PROMPTS=1 environment variable to log full system prompts to the interaction_log. Furthermore, goal ecology and deferred thought processing were reordered to ensure user message priority is maintained even during slow maintenance operations.

  • Added CHALIE_LOG_PROMPTS=1 to log full system prompt for meta-harness trace capture.

  • Moved goal ecology and deferred thought processing after idle timeout to prioritize user messages.

  • Dropped the focus skill and all references to FocusSessionService.

  • Added a goals schema to the goals_skill for structured create/list/view actions.

  • Migrated document_chunks_fts to use porter stemming for better inflection matching.

  • Increased document chunk distance_threshold from 0.65 to 1.5.
