Unit tests for the TypeSafe (Jev) compaction guardrail.
Tests cover:
- exchanges scored below relevance_threshold have their tool rows blanked while
assistant tool-call rows and kept exchanges pass through verbatim, without
mutating the caller's message list
- protected rows (system, last user, and the last tool exchange via the
last-assistant rule) are never sent to Jev even when long
- exchanges under min_chars_to_evaluate are skipped
- request shape: POST {api_base}/v1/systemone with Bearer auth, one noul
question per candidate keyed e<i>, task = last user text, results truncated
to max_result_chars_in_state
- identity return when there are no candidates or nothing is dropped
- fail_open forwards uncompacted on service failure; fail_closed raises
