Refurb Workflow Diagrams

[HYPOTHESIS] — these diagrams describe the designed Boot Up pipeline (Phase 0). They are the working blueprint, not yet validated against a real cohort; steps will change once the first batch runs.

A donated or surplus machine moves through five stages: Acquisition → Intake → Sanitization → Install (Ubuntu + BNI Community Pack) → Ready for User. Units that can't be recovered are routed to responsible recycling or parts harvest.

1 — Acquisition

Three supply streams feed the program. Institutional surplus arrives stripped (destroy-drive policy), so power cords and drives are the parts the program must fund.

2 — Intake & Triage

Every unit is logged, ownership is transferred in writing, and a minimum-spec gate keeps volunteer labor off machines that cost more than they're worth.

3 — Sanitization

Boot Up always performs a verified, certified wipe at intake — a donor's self-wipe is a courtesy, not the system of record. The method depends on the media type. (Full detail: Data Sanitization & Wipe Certificate; donor-side options: Donate a Laptop.)

4 — Install: Ubuntu + BNI Community Pack

A clean Ubuntu 24.04 LTS base, then the curated BNI Community Pack of open-source apps and accessibility defaults. (Stack detail: Software.)

    E --> F(["To QA / Ready for User"])

[HYPOTHESIS] MPowerUP preinstallation depends on a desktop/web build of MPowerUP (its Phase 5) — shown as a future step, not a current capability.

5 — Ready for User

A QA gate confirms the machine actually works for a real person, then it's matched to a curriculum graduate and handed over with support.
