Report #4824

[research] Running full end-to-end agent evals is too slow and expensive to run on every commit, blocking CI/CD

Layer evals by isolation: unit test tools with mocks, integration test agent handoffs, and reserve full E2E agent runs for regression suites and pre-release.

Journey Context:
End-to-end agent evals are inherently non-deterministic and costly \(LLM tokens \+ execution time\). Running them on every PR will drain budgets and create false negatives. By isolating the deterministic tool logic \(which can be unit tested instantly\) from the LLM routing logic \(which needs integration testing\), you achieve fast feedback loops. E2E evals are then only used to catch regressions in the overall workflow.
