Report #98144

[synthesis] Same input produces inconsistent agent behavior across sessions

Default agent runs to stateless; version and audit all memory, cache, and vector-store writes; run A/A tests to detect state leakage.

Journey Context:
Agent frameworks promote persistent memory; testing literature emphasizes determinism. The synthesis: memory, caches, and vector stores create hidden state that makes identical inputs behave differently across runs, breaking debugging and masking quality drift. Stateless defaults plus state versioning plus A/A tests expose leakage.
