Where: Pre-migration ESTM row 52240019
Labels the row Surface/Name Snow, leaves Origin null, and stores four 1.1/0.602/4170000 layer triplets. This establishes migration identity and values only.
Where: SUEWS legacy ESTM release history
The 2017a tuple appears as Water code 813; both 2017b occurrences are labelled Water. From 2018a through 2020a Snow code 61 uses a different tuple and is labelled snow dummy code row.
The adjacent Water migration row 52240021 has the same four active layer triplets. This numeric identity is recorded for curation but does not authorize merging or deleting either stable record.
| Name | supported Archived Snow-labelled ESTM migration row identifies exactly what the retained artifact proves without presenting it as a physical snow parameterization or claiming why it was created. |
|---|---|
| Target | supported The pre-migration ESTM row is labelled Snow. Modern SnowParams has no thermal-layer fields, so migration retains the columns only under legacy and the record exports no active model parameters. |
| Values | supported The empty canonical parameters mapping and exact legacy columns faithfully preserve the migration artifact. The four layer triplets are value-identical to the adjacent Water row but are not promoted as snow values. |
| Source | supported Unreferenced is correct because the workbook row has no Origin and its former Kawai link was an arithmetic reference-fill artifact removed in PR issue #395 |
| Place | not applicable The migration row has no Origin and makes no observation-place claim. |
| Representativeness | not applicable An archived migration row with no active parameters makes no evidence-reach claim. |
| Method | supported Assumed describes the repository curation decision to retain the ambiguous row as an archival configuration artifact; it does not assert the original compiler's intent. |
| Identity | supported Legacy ID 52240019 remains a distinct Snow-labelled workbook row. Retention does not decide whether its duplication of Water was a placeholder, transcription error, or deliberate choice. |
The evidence establishes an ambiguous Snow-labelled migration row, not a physical snow parameterization. Its canonical parameters remain empty and its legacy payload remains exact, so no snow value reaches an export. The archival name and assumed method make that status explicit while preserving stable identity and avoiding an unsupported claim about whether the water-profile duplication was deliberate or erroneous.
