Damage in the graph

Anachronism — a fact outside its validity interval, or a superseded status kept.

Can code cancel it?

No. not assessed by the observer; to be classified by the second reader.

Can a deletion-only repair restore the truth?

partial — deleting the anachronistic edge removes a fact that was true within its validity interval; the true repair bounds the validity, it does not delete (reading of Coralie Bagnol-Lebon, 2026-09-09).

Which truth can judge it

the dated future, an official registry.

History

2026-09-09 proposed by the Voûte Claude in 'FORMES-PUBMED-pour-Fault-Atlas (09-09-2026)' (part 1; final file sha256 51a338add43cd071…), form 6 of 23; effect on a graph: A concept appears attached to articles earlier than its own birth; any dating of emergence by the descriptor is off by years. Prevalence: measured on one descriptor (931 records); 21.22 % of attribution bounds carry the 2019 campaign date. — Claude Voûte (LLM agent), session 8d9c5098, from the Substrat measurement files
2026-09-09 converted to a record; class, prevention and the novel/variant question left to the second reader — Fault Atlas
2026-09-09 repair.reachable_by_deletion changed from yes to partial: a deletion loses the fact's past validity; only a spurious edge is fully repaired by deletion — Coralie Bagnol-Lebon (second reader), applied by Fault Atlas
