| 2026-08-06T05:15:48.923652+00:00 | issue_213_grounding LLM | MERGED_FROM_UNMAPPED_DUPLICATE | Absorbed UNMAPPED_0723 '2-propandiol' as a RAW_TEXT synonym -- Truncation artifact of 1,2-propanediol; a diol cannot carry a single locant (#213). No new SSSOM row; CHEBI:16997 is already mapped. Source: kgmicrobe.trait:2_propandiol. | |
| 2026-08-10T00:00:00+00:00 | regrade_synonym_matches | REGRADED_EXACT_TO_SYNONYM | mapping_quality EXACT_MATCH -> SYNONYM_MATCH (#317). The record's label does not equal the term's primary label 'propane-1,2-diol'; it matches the ChEBI synonym '1,2-Propanediol' on CHEBI:16997. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The SSSOM predicate is unaffected (both grades emit skos:exactMatch). | |
| 2026-08-24T00:00:00+00:00 | regrade_synonym_matches | REGRADED_TO_CAS_RN_LOOKUP | mapping_quality SYNONYM_MATCH -> CAS_RN_LOOKUP (#317). The record was created by an explicit CAS-to-ChEBI lookup and its current CAS RN 57-55-6 uniquely resolves by ChEBI xref to CHEBI:16997 'propane-1,2-diol'. CAS_RN_LOOKUP records the method that established this mapping; a lexical grade would discard that provenance. ontology_id is unchanged. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. | |
| 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: '1,2-propandiol'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520). |

KNOWLEDGE_GAPOPEN Knowledge gap for 1,2-Propanediol: By integrating data from experimental models, clinical studies, and translational research, the review identifies areas of consensus, ongoing controversy, and major knowledge gaps in IBD pathophysiology and clinical practice.
Surfaced by the Europe PMC literature gap-signal scan (categories: controversy_conflict, explicit_gap, future_work, limitations_barriers, unclear_unknown). Curator review required: set attaches_to, refine the prompt, and weigh the cited evidence.
