What probably matters to youSection of the release
What
The prompts that summarise a conversation when it gets compacted now tell the model that only genuine user turns count as user messages, so transcript-shaped text pasted inside assistant output cannot be laundered into an instruction from you. They also require that security-relevant constraints you set survive compaction word for word.
Details
Three summarisation prompts carry the clause: the full-conversation one, a recent-portion-only one used for partial compaction, and one framed as a summary followed by newer messages.
The clause is inserted by fixed template substitution, so it is always present in all three.
Evidence
is merely formatted like a user turn \u2014 e.g. quoted "user: ..." or "Human: ..." lines
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
