Every EDR (category: endpoint) integration is now audited for an OCSF mapper. Six had a fetch command but no mapper — add a bundled OCSF mapper for each, wire the fetch command as an ingestion source (ingest: results_path/dedup_key [/incremental_field]) and add the top-level ingestion block. Field mappings were derived from each vendor's fetch output and cross-referenced against the demisto/content reference for that vendor. - carbon-black-cloud: search_alerts (results_path results, dedup id) — 35 fields - cisco-secure-endpoint: list_events (data, id) — 21 fields - cybereason: query_malops (malops, guid, incr start_time) — 6 fields - sophos-central: list_alerts (items, id) — 14 fields - trend-vision-one: list_alerts (items, id, incr start_datetime) — 19 fields - withsecure: list_incidents (items, incidentId) — 7 fields Validated: every manifest passes ParseManifest+ValidateManifest and every mapper passes ParseMapperFile with all JSONata source_path/field expressions compiling.
