📋 Decision Context

Question:

Is S209 Phase 2.0 (fix training data flow so ai-api is source of truth) already implemented or does it need work?

Task: S274: Verify S209 Phase 2.0 training data flow status

🎯 Decision Made

Chosen:

Confirmed fully implemented — no additional work needed. getTrainingExamplesForAgent() exists in BackendAiClientService with 2s timeout, REST endpoint supports agentId filtering, buildSystemPrompt() has remote→embedded fallback, and both spawnFromDefinition() and executeTask() call it.

Options Considered:

  1. Implement from scratch per S209 plan
  2. Verify existing code covers the plan requirements (chosen)
  3. Skip verification and assume done based on S210 memory

💭 Reasoning

The S209 plan (Phase 2.0) prescribed 3 implementation steps: (1) Add getTrainingExamplesForAgent to BackendAiClientService, (2) Update buildSystemPrompt to prefer ai-api, (3) Verify TrainingDataService supports agentId filtering. Deep code inspection confirmed all three are already implemented with proper error handling and fallback. The S210 memory noted '18+ features implemented' including training flow. Verification via code reading is more reliable than trusting memory alone — prevents wasted effort implementing something that exists, and catches any regression since the memory was written. Key finding: the implementation matches the plan exactly, including the 2-second timeout and graceful fallback to embedded examples.
