AROS Procurement Portal™ — Architecture & Schema #DontMessWithX

By Albert Lane (@AlbertLane_net) · Nov 9, 2026 · Live app: aros.albertlane.net/os/procurement · Source MegaPrompt: PDF (sha256 2874243da16156df29e1fb7312dfa06f2530b1650423b50d4f3c0f9547c44821)

This page describes what is actually built and running. Nothing is simulated: every number in the portal comes from a keyless public source fetched live, or from a row a signed-in person entered. Anything that needs an account or key is listed as Not connected yet. The portal never moves money, never signs or broadcasts anything on a public blockchain, and stores no wallet address.

2 · User flow

Open AR^OS (aros.albertlane.net) and tap the Procurement™ tile, or go straight to /os/procurement.
Pick a state. The list of states comes live from the US Census TIGERweb service.
Pick a county. Its real boundary is drawn over NASA satellite imagery; switch between true color, NDVI and Landsat, pick a date, pan and zoom.
Read the county's real crop acreage (USDA Cropland Data Layer, satellite-classified, latest year available).
See the catalog ranked by how its items' crop tags match the crops actually grown in that county. The catalog starts empty: owners/engineers add real items with a real supplier and (only if they have one) a real quote and its source.
Sign in with the AR^OS passkey (Face ID / fingerprint). Without it nothing can be requested.
Record a request: county + item + quantity + note. The Worker writes it to D1, appends a SHA-256 linked entry to proc_ledger, and mirrors it into the AR^OS audit chain. You get back the entry hash.
Anyone can check the chain at /os/api/proc/ledger. Nothing is broadcast to any public blockchain, nothing is paid, and no wallet address is used.

4 · Smart-contract-style data schema

JSON Schema for one procurement record (also live at /os/api/proc/schema). Field names follow ISO 20022 (EndToEndId, InstdAmt, Ccy, Dbtr, Cdtr) and ERC-3643 identity ideas where natural, as names only: the purchaser is an AR^OS passkey account, not a wallet address.

SkyFi imagery — needs SkyFi account + API key
Sentinel Hub NDVI statistics — needs Copernicus Data Space / Sentinel Hub OAuth client
NASS Quick Stats county yields — needs free NASS Quick Stats API key
IPFS storage — needs self-hosted IPFS node or pinning account
Public-chain anchoring / escrow contract — needs a wallet Albert holds, his approval, and gas — not done by design
Per-county numeric NDVI — needs raster statistics service or GPU/GDAL node

8 · From the MegaPrompt, deliberately not built

HTTP 402 / L402 paywall for crawlers and embedded payment addresses — no payment routing or wallet address is published (owner rule).
Solidity escrow contract deployment — nothing is deployed to any chain; the schema above is the off-chain record.
zk-SNARK yield verifier, 8×GPU air-gapped cluster — needs hardware and data we do not have.
Automated cease-and-desist dispatch — not built; nothing is sent automatically.
