name: Synthetic Deterministic Tests

# Regression guardrail: run every offline (no-LLM) synthetic test on every
# PR and merge so pipeline refactors can't silently break investigations.
#
# Tests that need a live LLM are excluded via the marker filter below.
# Those suites live in interactive-shell-live.yml and hermes-tests.yml instead.
