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: 'Sodium dihydrogen phosphate'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520). | |
| 2026-09-21T21:33:25.379198+00:00 | mim_semantic_review_20260921 LLM | MERGED_INTO | REJECTED | Merged into CHEBI:34683 (Na2HPO4). Dibasic sodium phosphate is disodium hydrogenphosphate, not trisodium phosphate. Sodium dihydrogen phosphate is monobasic and is a REJECTED_LABEL here; its 78 recipe rows are excluded from this transfer. Original fields remain only on this excluded tombstone.

| 2026-10-05T04:09:33.941715+00:00 | fix_tombstone_pointers | REPOINTED_TOMBSTONE_IDENTIFIER | identifier CHEBI:37583 -> CHEBI:34683 (#799). This record was merged into 'Na2HPO4' but kept its own old identifier, so a downstream lookup on this label resolved to nothing live. The target is the one named in this record's own MERGED_INTO entry; the chain was followed to the first live record. A tombstone exists to keep the loser resolvable. | |
| 2026-10-05T04:09:33.941715+00:00 | fix_tombstone_pointers | REFRESHED_TOMBSTONE_ONTOLOGY_ID | ontology_id CHEBI:37583 -> CHEBI:34683 (#799). The merge set identifier and status but left ontology_mapping untouched, so this tombstone kept advertising a term it no longer asserts — anything indexing by ontology_id routed through it. Now agrees with the merge target 'Na2HPO4'. Provenance is unaffected: what the record used to assert is in this history. |
