Preserve Research Attribution Across Combined Files
Append field-level observations, distinguish current and planned facts, and retain source-to-decision traces when combining account research files.

Combining research files often preserves the latest value while discarding where it came from. A company region then appears authoritative even though one file inferred it from a job advertisement and another recorded a direct correction. Without attribution, the next reviewer cannot distinguish stronger evidence from a newer copy.
Append observations before choosing canonical values. Keep each relevant claim connected to its source, entity, observation date, and any stated effective date. The resulting evidence ledger can support a reviewed current value without pretending the discarded alternatives never existed.
Separate a source row from a business fact
A row may contain several claims with different origins. The company name might come from an official site, the region from a licensed directory, and a service interest from an authorized conversation. One source label for the whole row can misattribute all three.
W3C's Data on the Web Best Practices recommends providing provenance information. The field-level ledger here is a practical editorial implementation, not a requirement to adopt the complete W3C model. Keep the detail proportional to the decisions the research supports.
Use an internal observation reference, entity reference, field, value, source reference, checked date, effective date when known, and evidence status. Add source-use restrictions where they affect the proposed combination or handoff.
Work through a fictional append
Two authorized synthetic files describe account A31. File Red says service_region is West, checked in February, based on a company page. File Blue says Central, checked in April, based on a service-coverage announcement that explicitly says its service region will change from West to Central in July.
Observation O91: A31, service_region, West, source Red page reference, checked February, current status unconfirmed.
Observation O92: A31, planned_service_region, Central, source Blue announcement, checked April, expected effective month July.
Canonical decision D14: retain the distinction between current and planned region; do not replace West with Central merely because Blue was checked later.
Follow-up question: confirm whether the announced coverage change took effect before using Central as the current service region.
The combined artifact contains both observations and the decision. It does not need duplicate copies of entire web pages if a permitted reference and concise claim record are sufficient.
Detect conflicts before selecting survivors
Group observations by reviewed entity and field, then identify incompatible current claims. Check whether they refer to different branches, time periods, or definitions before calling them contradictions. Group-level revenue and subsidiary revenue should not compete for one unqualified field.
Choose canonical values through a documented rule that considers source relevance, effective time, and verification. “Newest file wins” is rarely enough because a fresh export may contain old research. Preserve uncertainty when the evidence does not support a single current value.
For personal-data corrections or contact restrictions, apply the appropriate authority and privacy process rather than a generic source-ranking rule. A direct stop request must not be outvoted by several older files with empty preference columns.
Keep append operations traceable
Assign each combined batch a run reference. Retain the source-row-to-observation mapping and record transformations such as whitespace cleanup, field renaming, or date normalization. That lets a reviewer trace a canonical value back through the combination without keeping unnecessary copies everywhere.
Test duplicate ingestion. If the same file is appended twice, the ledger should identify repeated observations rather than treating repetition as independent corroboration. A document copied into three folders is still one source. Choose stable observation identity rules and retain enough version context to distinguish a genuine update from a repeated copy.
In the fictional example, importing File Blue again in May should not create a second vote for Central or reset the announcement's effective date. The process should recognize the repeated evidence and preserve the original claim context.
The acceptance check is a reverse trace: select a current value, find its decision record, inspect its supporting observations, and open the permitted source references. Then select a rejected or unresolved alternative and confirm it remains understandable where retention is justified. A combined file is ready when its important claims remain attributable, not merely when every column is filled.
