| 1 | //! Additive, reviewed extension instructions in the existing Engine session history. |

| 3 | //! There is no prompt store or turn loop here. Each turn captures sections from |
| 4 | //! its own attachment, validates the Native receipt, and rechecks owner and |
| 5 | //! attachment after that asynchronous check. The Engine records the complete |
| 6 | //! captured block as a runtime history snapshot replacing earlier snapshots, |
| 7 | //! so no instructions are lost to a truncated workspace delta and the system |
| 8 | //! prefix stays stable. Activation is asynchronous: a first turn before owners |
| 9 | //! are ready sees no sections; a later turn captures them after reconciliation. |
