Three workstreams can each see their own column. Nobody can see the row.
Fifteen questions asked of one materialised graph, answered with the query that produced them. The graph does not perform matching — it consumes linkage output and records what happened, so every answer on these screens can be traced back to the record it came from.
SPARQL
Prefixes the project's shared prefix set, prepended to every query
One person, drawn
Logins are merging onto one identity platform, parties into the party service, accounts into one core. Each of those programmes can see its own column. This view draws the row.
Identifiers, all retained
Every source key survives. The enterprise identifier is one row among several, not a replacement for them.
The overlap figure is not a fact. It is a function of a threshold.
Move the threshold and the count moves with it. That turns an unanswerable question into a business decision with an owner — which is worth more than any single number.
How the assertions landed
Decisions at the operating thresholds — auto-merge 0.90, review 0.70. These do not move with the slider.
Everything that happened to one party
Where each contributing record came from, what evidence linked them, which values survived and what was discarded — on one screen, in reading order.
