The event, sensor and recipe records required to reconstruct every FlavoRotor cultivation run.

In brief

The event, sensor and recipe records required to reconstruct every FlavoRotor cultivation run.

**Monitoring interface.** Original software prototype screen from the project report. [I01]

**Historical record view.** The interface supports traceability only when stored values retain sensor, calibration and recipe identifiers. [I01]

## Reconstruction requirement

An independent analyst must be able to reconstruct what the system was commanded to do, what it actually measured, what deviations occurred and which samples were harvested.

## Core data streams

FlavoRotor data architecture; MIAPPE and FAIR concepts are described in sources R23 and R24. [I01] [R23] [R24]

 |
 Stream | Examples | Primary key

 | System state | mode, faults, firmware, system version | timestamp + system_id
 | Sensors | pH, EC, temperature, level, PPFD reference | timestamp + sensor_id
 | Actuators | pump steps, channel, rotation command, light state | event_id
 | Recipe | time-indexed setpoints and limits | recipe_id + version
 | Biological material | species, cultivar, seed lot, position | sample_id
 | Observations | mass, image, colour, chemistry, sensory | observation_id
 | Calibration | model coefficients and validity | calibration_id

## Time integrity

The controller and server clocks are synchronised before a trial. Records use UTC internally and retain the local timezone for human-readable reports. Missing intervals are represented explicitly; time series are never filled silently.

## Metadata standard

The study package follows MIAPPE concepts for investigation, study, biological material, environment and observed variables, and FAIR principles for durable identifiers and machine-readable metadata. [R23] [R24]

## FlavoRotor design provenance

The system-specific configuration on this page is traced to the supplied FlavoRotor engineering records. [I01]
