Hydration Systems Overview
Architecture of the three Beanwater instruments, their shared data path, the twelve-node reporting network, and the relationships between them.
1. Purpose
This document describes the architecture of the three Beanwater instruments and the relationships between them. It is intended for internal readers who have been asked how the system works and have discovered they do not know.
2. System inventory
| Code | Instrument | Division | Primary layer |
|---|---|---|---|
| ATM-001 | Wetness Index™ | Atmospheric Intelligence | Near-surface atmosphere |
| ATM-002 | Global Hydration Index™ | Atmospheric Intelligence | Distributed atmosphere |
| AGR-001 | Beanfield Futures Desk™ | Agricultural Intelligence | Soil column |
3. Shared data path
All three instruments resolve a location, request environmental data, validate the response, normalize it into a common field object, and only then apply Beanwater calculations. The separation is deliberate: a retrieval failure and a calculation failure produce different states on screen, and can be distinguished without reading source.
Location resolution accepts a place name, a United States ZIP code, explicit coordinates, or browser geolocation. Coordinates supplied directly are not re-geocoded. Browser geolocation feeds the same calculation path as every other input method; there is no separate implementation.
4. Instrument relationships
Local Wetness Index calculations are interpreted in reference to Global Hydration conditions. Global Hydration classification incorporates regional atmospheric wetness. Both are consulted when assessing field-grade bean readiness, which is itself reported to Agricultural Intelligence as an input to the wetness environment.
This arrangement has been reviewed twice. On both occasions the reviewing party concluded that the arrangement was sound and that the other reviewing party should confirm it.
Implementation Note
The circularity described above is organizational, not technical. In software, each calculation is deterministic and independent: ATM-002 calls the ATM-001 formula, and AGR-001 calls neither. No instrument depends on the output of an instrument that depends on it. Attempts to implement the narrative relationship literally were discontinued.
5. Node network — ATM-002
Twelve reporting nodes are maintained: Milwaukee, New York, Miami, Phoenix, London, São Paulo, Cairo, Lagos, Mumbai, Tokyo, Singapore and Sydney. Four are designated agricultural and contribute additionally to Bean-Weighted Exposure.
Nodes are polled independently and settled collectively. A node that fails to report is excluded from the composite and displayed as unavailable; the index is then labelled a partial network calculation and annotated with the reporting count. Network health is classified as Normal, Degraded, Partial or Unavailable according to the proportion reporting.
Node identity is preserved by pairing each response to its request rather than to its position in a result set. This was not the original design. The original design is discussed in BWL-INC-0062.
6. Timestamp handling
Environmental data is requested in UTC and converted for display using the offset supplied with the response. This ensures that a node reports the hour occurring at that node, rather than the hour occurring wherever the reader happens to be sitting. Prior to Revision 4.0 this was not the case, and readings for distant nodes were confidently incorrect by the width of their time zone.
7. Limitations
- No instrument holds state between page loads. There is no history.
- There is no server component. All calculation happens in the browser.
- Soil data quality varies substantially by region and is poorest where it would be most interesting.
- The system measures the atmosphere. It does not measure beans.
This document is part of a satirical fiction. Beanwater classifications, thresholds and program names are invented and carry no scientific, agricultural, medical or regulatory standing. Where real environmental data is referenced, its provider is named and linked. See Methodology.
