Investor-owned utilities and cooperatives have spent decades proving that crews will travel to someone else’s disaster. That culture fails when the damage is everywhere at once, which is the EMP and great-storm case. It works remarkably well when the damage is regional.

The mechanism is agreements and a habit of picking up the phone, plus a yard that can spare a truck because its own weather is still ordinary. A regional storm is the case this was built for. The visiting crew brings practiced hands. The host still has to know its own system. The truck is a multiplier, not a substitute for a local plan.

Everywhere at once is the case where the utility you would call is in the same dark, with its own damaged equipment and its own towns. Mutual aid cannot borrow a crew from a region that is not there. That limit is the electromagnetic and great-storm case. It is a reason to describe the agreements accurately, not a reason to throw them out. They are not a national generator.

Underneath it, the unrest-resistant pattern is the same: people who already have a job. Who has water. Who checks the stairwell. Who watches the kids of the person standing in a generator line. None of that requires a vest.

The generator line is the example that makes the jobs concrete. The adult standing in it cannot also be the adult on the stair. If nobody was named, the line creates a second outage inside the building. Block-scale mutual aid is the earlier decision that the stair and the children belong to someone who is not in that line.

The work does not need a title because it is not an authority. It is recognition. The neighbor with water does not need a vest to share it. The neighbor who was never introduced will be slower to knock, and may not know which door needs it. Utilities keep that fact as a contact list. A building's version is shorter, and blank if it was never made.

Introduce yourself before the outage. Afterward is a worse time to learn your neighbor’s name. A name learned in the dark still counts. A name learned while nothing was wrong is a small crew the building already has.
