This guide is for you if your Quanta balance is at or near Φ0.00 and you need to survive until your next UBC deposit. It was written by Shelf residents for Shelf residents. It is not a corponation publication. It is not approved by the QFIC. It contains information that corponation-published guides deliberately omit. Read it. Share it. Don't store it on your BCI — print it if you can, memorize what you can't print.

ATMOSPHERIC PROCESSING AT ZERO: When your balance hits Φ0.00, your hab unit's atmospheric processor drops to 60% flow. This is survivable but unpleasant: headaches within 2 hours, fatigue within 4 hours, impaired thinking within 6 hours. To manage: open your hab door and let corridor air circulate — corridor processors run on the block's communal account and are maintained as long as anyone on the block has positive balance. If the entire block is at zero (end-of-month, we've all been there), go to a public commercial area — malls, transit hubs, commercial corridors — where atmospheric processing is funded by business infrastructure fees, not residential accounts. You can breathe free air in a transit hub for as long as you're willing to sit there. The security patrols will tell you to move along after 4 hours, but they cannot legally restrict access to public atmospheric zones. Know your rights. Breathe their air.

FOOD AT ZERO: The block dispensers require minimum Φ0.15 for a protein bar. If you are at true zero, your options are: 1) Community kitchens — every block has at least one, usually operated by an auntie who maintains a pool. Show up at 6 PM. Bring a container. Do not take more than one serving. 2) Temple and shrine meal programs — the Buddhist temple on Block 7 serves rice and vegetables at 11 AM daily, no questions, no Quanta required. The Sikh gurdwara on Block 12 operates a langar 24 hours. These are not charity. They are religious practice. Eat with gratitude and respect. 3) The "fallen fruit" market at the base of the Grind-Shelf transition zone — vendors at the market above drop damaged or unsold product down the waste chutes at closing time. Shelf residents collect it. Arrive by 9:30 PM. First come, first served. The food is not spoiled. It is cosmetically imperfect and therefore unsaleable to people who can afford to be selective.

EARNING QUANTA AT ZERO: When you need money now, not in 11 days: 1) Day labor at the Grind boundary — logistics companies hire daily for loading, sorting, and cleaning at Φ8-15/day in Quanta (not scrip — verify before accepting). Show up at the labor shape-up on Block 22 at 5 AM. 2) Data work through your BCI — several platforms pay Φ0.002-0.005 per task for image labeling, content moderation, and survey completion. The pay is terrible. On a focused 10-hour day, you can earn Φ2-4. It is not enough and it is better than nothing. 3) Sell blood or biometric data — Vossen medical facilities pay Φ5-8 for a blood draw and Φ3-5 for a full biometric scan. You can sell blood once per week. Biometric scans are unlimited but the data goes to behavioral modeling databases. 4) Check the Quanta pool schedule — if you are a member of a pool, your payout may be negotiable for emergency advancement. Talk to your auntie.

WHAT NOT TO DO: Do not take scrip-denominated day labor unless you are already in that corponation's system. Scrip earned outside employment is converted at 0.40-0.50 on the dollar. Do not sell BCI processing time to unlicensed buyers — this can install malware that turns your BCI into a mining node for criminal operations. Do not borrow from informal lenders who charge per-day interest — the standard Shelf loan shark rate is 3% per day, which turns a Φ10 loan into a Φ20 debt in 24 days. If you are in crisis, reach out to the Mutual Aid Network at the community board on your block. We have been at zero. We know the way through. You are not alone.
