What
A new piece of per-turn context, computed from the active tool set, tells the model what sandbox it is running in. It is added on both the queued-prompt path and the per-turn attachment list, and is compared against the previous one so it is only re-sent when it changes.
Details
It sits alongside the existing date-change and agent-listing-delta context items, and is handled the same way as the agent listing when diffing.
Nothing in the code shown gates the attachment itself.
