Eighteen visits queued from yesterday. Nothing is lost when the tower drops out.
Chapter 00 — The Thread
Transparent supply chains, empowered communities.
Zamba engages farmers as active partners and equips coordinators with the tools to manage education, scheduling, and participation — building secure and transparent supply chains together.

Chapter 01 — One Plot
1.4 hectares, and a boundary that exists on a map.
Plot 0417 sits at 640 metres in San Martín. It has a surveyed edge, a soil record, and a name attached to it — not a farmer ID. A name.

Chapter 02 — The Farmer Decides
The farmer decides. Everything else is bookkeeping.
I decide what I plant and when I sell. What I needed was a record I could hold — one that says what left my plot, and what came back.

Chapter 03 — The Coordinator's Day
A day that works without signal.
Six plots, ordered by walking distance — not alphabetically, not by ID.
Compost dosing at the cooperative hall. Forty-one attendees expected.
Attendance recorded per farmer, per topic, per date. Synced at the first tower.

Chapter 04 — The Lesson
Participation is recorded, not assumed.
Every row is a date, a topic, and the names of the people who showed up. Exportable, auditable, and signed by the coordinator who ran the session.
Certifiers ask for evidence of training, not intentions. Zamba answers with a ledger the cooperative already keeps for itself.

Chapter 05 — The Harvest Becomes a Batch
Weight, date and moisture collapse into one ID.
The thread pulls taut. What was a pile of dried beans becomes a record that can be followed all the way to a shelf — and back again.
