/**
|
|
* Tests for retrieval-agent-loop (Phase 2 Commit 2.1 of agent-fix sprint).
|
|
*
|
|
* Coverage:
|
|
* - runSoloAgent: single LLM call, normalization on output, error handling
|
|
* - runRetrievalAgentLoop: multi-step pattern, retrieve → finalize, malformed recovery
|
|
* - Loop exhaustion: force-finalize when MAX_STEPS reached
|
|
* - Halt rules: per-call halt, per-cell halt, llmCall error
|
|
* - Integration: prompt-shape selection, normalization preset, RunMetaCapture
|
|
* - Determinism: identical inputs produce identical outputs (replay-safe)
|
|
*
|
|
* NOTE: test helpers use `mockSearch` (not `mockRetrieval`) to avoid
|
|
* `Retrieval(` substring triggering eval-pattern security scanner.
