This is written from the worst possible starting point: no stored water, no torch with batteries, no radio, eleven dollars and a quarter tank of fuel. Every day is one more day of the same emergency. The techniques that keep him alive are real and cited; the mistakes are the ones people actually make, which is why they are in here.
Day 0 and Day 1 are live. A new day is released every morning — the roadmap below is the whole arc, so you can see where it is going.

Two days of water left and a bathtub I cannot use. Why counting litres per person beats hiding the bottles. Live now.

Sanitation is the part of a grid-down week that actually gets people sick.

Building a heat trap out of a bedroom, and why the car is not the answer.

What I can actually eat, and the canning rule that keeps it from killing me.

A quarter tank, eleven dollars, and the queue at the one open shop.

Three counties of rumour, one real number, and how I finally got a radio.

Tired, cold, and making worse decisions. The human failure is the one the books warn about.

Snow, a creek and the filter question — and what boiling cannot fix.

A prescription with four days left and a pharmacy with no power.

Someone is walking the street at 2 a.m. What a lit window tells them.

The one appliance I can still use, and the two I must never bring inside.

Layering, ventilation, and the carbon-monoxide arithmetic I keep coming back to.

What a working generator really costs to run, and why the CO rule almost got broken twice.

An audit done by living in it, in the cold, for a fortnight.

Why the standard 72-hour kit does not fit a household with a diabetic in it.

Splinting, closing a wound, and the 12-hour rule that decides whether a cut becomes an infection.

The unglamorous work that keeps people functional.

The power comes back for three hours, and everyone stops being careful.

What actually has value when money does not, and what I had worth trading.

151 litres sitting behind a valve I did not own the hose for.

How much is really in the lawnmower, the car and the cans.

A fire in a cold house, and how fast a bad night becomes a catastrophe.

Schooling, boredom and fear, when the routine is gone.

The hall with the generator, and why the town is functioning while my street is not.

Rural water after a fortnight of frost.

The decision quality problem nobody plans for.

Four specific things, in order of how close they came to killing us.

Buying, storing and fixing while the thing is still happening.

The crews, the estimate, and the risk of the last mile.

What a prepared version of me would have had on day zero, costed honestly.
The point of the serial is the list at the end of it. Everything he wishes he had on day zero is already written down — 75 scored questions across ten domains, and the spreadsheets that turn "I should get more water" into litres and a date.
