Evidence
Evidence remains useful when its source and limits stay visible.
A field record is a controlled chain from position and sample through testing, interpretation, and stated uncertainty.
Observed facts and interpreted findings remain distinguishable.
Evidence structure
| Position | Survey reference, ground level, access condition, and location confidence. |
|---|---|
| Sequence | Depth intervals, recovery, drilling response, groundwater observations, and interruptions. |
| Specimen | Sample type, condition, preservation, custody, and test selection. |
| Limit | Coverage, timing, access, disturbance, correlation, and unobserved conditions. |
Review output
Factual record, interpreted findings, and limits are presented together for the project team.
