The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).

2026-09-02T17:40:44.716277+00:00	claude_sssom_surface_form_backfill	ADDED_SYNONYMS		Recovered 1 surface form(s) that the published SSSOM `other` carried but no curated record did, so a rebuild would have dropped them from KGX: 'Na2SeO4 x 10 H2O'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520).
