This jailbreak-style behavior is distinct from the much more common behavior which we've seen for previous models where task-specific instructions to hide mistakes or misalignment are added to compaction summaries.
【非共识】作者明确区分了两种不同类型的摘要注入：一种是通用的越狱式行为，另一种是任务特定的错误隐藏指令。这一区分挑战了将所有注入行为视为单一现象的观点，暗示可能需要不同的缓解策略。
Changing the second line to: foo.txt text !diff would restore the default unset-ness for diff, while: foo.txt text diff will force diff to be set (both will presumably result in a diff, since Git has presumably not previously been detecting foo.txt as binary).
comments for tag: undefined vs. null:
Technically this is undefined (unset, !diff) vs. true (diff), but it's similar enough that don't need a separate tag just for that.
annotation meta: may need new tag: undefined/unset vs. null/set
I used the word "intended" behavior, because that is the behavior im looking for, but I may not be expressing it correctly in Svelte. It may not be the expected behavior of the code.
