Report #103900

[architecture] Tool results and intermediate reasoning leak back into the agent's permanent memory

Label every observation with a retention class before storage: ephemeral, summarized, or archived. Never archive raw tool outputs or chain-of-thought traces verbatim without explicit extraction.

Journey Context:
Agents produce a lot of transient text: search snippets, calculator outputs, failed reasoning paths. If the memory layer naively embeds all of it, the vector store fills with noise and future retrievals get polluted. The fix is to classify observations at write time. This is not the same as prompt filtering; it happens upstream in the memory pipeline. It also protects against instruction smuggling, because tool output should never become a privileged instruction in a later turn.
