[research] End-to-end agent tests alone make debugging multi-step failures a guessing game

Use three testing tiers: component tests for reasoning, tool calls, and memory in isolation; end-to-end scenario tests with normal, hard, adversarial, and historical-failure cases; and continuous production monitoring with trace-level sampling and anomaly detection.

Journey Context:
Component testing isolates whether the failure is in the LLM, tool interface, or retrieval layer. Scenario testing finds emergent failures that only appear when components interact. Production monitoring catches unknown unknowns. A dataset built from real incidents is more valuable than synthetic happy-path cases: each fixed bug becomes a permanent regression guard. This tiered approach prevents debugging by grepping logs and replaces it with targeted, reproducible failures.
