Report #40104

[synthesis] Cascading state corruption from unvalidated intermediate tool outputs

Treat all tool outputs as untrusted data; apply schema validation and sanity checks before feeding output from Tool A into Tool B.

Journey Context:
Tool A returns a string with an extra newline or hidden character. The agent passes this directly to Tool B as an ID. Tool B fails cryptically or, worse, matches the wrong entity. The agent proceeds with the wrong entity. The synthesis is combining the 'garbage in, garbage out' principle with the lack of strict typing in LLM text processing and the compounding effect of unvalidated state.
