Within one loaded continuity, the same completed act remains true after return, death, quit, load, or a later shift unless its owning rule says it is temporary. Under the provisional single-line policy, ordinary loading does not roll it back; the disclosed recovery fallback and reloadable alternative are explicit exceptions, not owner-set prohibitions. One item cannot exist in two places and spent oxygen or material cannot reappear within the loaded history. Everything in the astronaut's carried property at death returns aboard, including each active rig part and each inactive or loose cargo item once. Something dropped, consumed, handed over, or installed in a station/ship fixture or another location outside that carried set does not. Loading and quitting cause no death, shift, delivery, completed work, or new knowledge.

| **Object instance** | One reusable part, canister, objective item, or loot object with one definition and exactly one current location/state | Astronaut-carried property contains active rig equipment and inactive/loose cargo as distinct substates, each counted once. Station/ship fixture, deposit/recipient, world source, and consumed are outside that set and mutually exclusive with it. “Collected” is a past event, not a current location. Fill, stored charge, and rig links belong to the same instance. |

| **Survivor** | One authored person, last confirmed transfer state and source, and—once resolved—their actual location/state | Never cargo. Waiting, Prepared, In transfer, At abort refuge, and Sent are not interchangeable. Sent commits only when this same survivor has completed arrival aboard and the required ship airlock is closed; confirmation provenance remains separate from world state. |

2. **Partition property once.** Snapshot the astronaut-carried membership by object identity: every active rig part plus every inactive/loose cargo item, each once. Move those same instances aboard, preserving rig-versus-cargo substate. Leave station/ship-fixture installations, deposits, handovers, world-source objects, and consumed resources outside the return set in their actual states. For example, an active Sensor and Projector, an inactive loose Fork, and a carried partial canister return once each; a different Fork in a station fixture and scrap already consumed by a Cycler do not. Restore ordinary condition for the next expedition under the current rule; ship-side refilling remains separate.

| **4. Journal and history** | A committed still and note identify a room and route in arrangement 12. Quit and load occur before death. | Both retain their recorded time, place, source, and claim on resume; unchanged arrangement does not verify their interpretation or present truth. Any resumed live reading is separately observed. After death creates arrangement 13, the records persist, route/adjacency claims become historical, and a known installed part or cut bolt remains a durable fact. No unseen route, translation, or corrected conclusion appears. |
