One custodian, one fate
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
In classical transmission a text's survival odds compound across many independent copies in many libraries; the Anglo-Saxon charter had no such redundancy. There was no royal registry keeping duplicates, and a church copied its own muniments, not its neighbours' - so nearly every charter descended a single custodial line, the beneficiary house and its books. The witness-count analogue is exact and countable: how many items in the Electronic Sawyer have medieval witnesses from two or more distinct archives? Where a Greek gospel might have hundreds of independent carriers, an English diploma almost always has one, and the overlap share measures the redundancy of the whole national record. The consequence for loss is structural: survival was not independent attrition, item by item, but correlated catastrophe - when an archive died (and item 2's census says most did), its unique holdings died as a block, with no second line anywhere to restore them. A near-zero overlap share is therefore the reason the corpus cannot self-correct, and it converts the archive-extinction rate directly into a document-extinction rate: the probability a charter survived is, to first order, the probability its one custodian survived, times the internal survival of that custodian's chest. The double-copied exceptions - texts entered in two houses' books - are the rare places where the record cross-checks itself, and their very rarity is the measurement.
Prediction clause (verbatim)
Prediction: the share of Electronic Sawyer items whose recorded medieval witnesses (single sheets plus pre-1500 copies) come from two or more distinct medieval archives will be at most 0.05 and at least 0.003 (primary clause: the sub-0.05 multi-archive overlap share; the verdict follows it). Disambiguation pinned: the two Canterbury houses count as distinct archives; post-1500 antiquarian transcripts do not create a second archive; witnesses whose medieval custodian cannot be assigned are excluded item-wise. Coverage guard: the test voids if witness custody is unassignable for more than 15 percent of items.
Kill-dataset (verbatim)
Kill: the Electronic Sawyer manuscript fields parsed item by item to medieval custodial archives, counting items with witnesses in two or more archives.

How this item is catalogued
Catalogue tags are curatorial metadata that make the conjecture findable. They are not findings, not a novelty verdict, and naming a source family is not a promise that the data exist or are accessible. Each dimension below says whether it was assigned, reviewed with none applying, uncertain, or not yet reviewed, and who recorded it.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Fresh blind generation by claude-fable-5, 2026-07-18, Anglo-Saxon charter wave anchored to the Electronic Sawyer (esawyer.org.uk): every kill names an open catalogue or standard edition and a countable operation - survival-form census, archive-concentration geometry, mentioned-but-not-extant joins, document-type concentration, presence/absence differentials - with thresholds far from 1 and explicit coverage guards separating loss from the accidents of ecclesiastical archive survival. Disjointness discipline: the w21 law wave (2026-07-10) already owns, on the same instruments, forgery-production timing (w21-001), forged-date targeting of archive gaps (w21-006), interpolation-vs-fabrication typology (w21-011), post-destruction restorative forgery (w21-018), authenticity-by-transmission-form adverse selection (w21-029), linguistic updating of boundary clauses (w21-014), cartulary content triage (w21-007), and endorsement campaigns (w21-030); this wave's item 7 (cross-archive spuria concentration, pure catalogue geometry, no timing or causality claim), item 1 (marginal single-sheet share, no authenticity cross), item 12 (cross-archive lease-type concentration, deliberately framed as the calibrating exception to w21-007), and item 14 (omission of bounds in late transmission, not updating of surviving bounds) reuse those instruments under different countable operations, flagged here. w15-004 owns capture-recapture population estimation on charters; item 4 measures custodial-line overlap as a fragility share and makes no population estimate. Drops during generation: a royal-registry-zero census (threshold degenerate near certainty), a folkland undocumented-tenure item (not countable), a nunnery-archive census (adjacent to w23 women territory and the Veiled Women join is not yet data), an Anglo-Saxon wills concentration item (Bury registry join uncertain), and a Peterborough pre/post-refoundation survival cliff (collides with w21-018). Items 9, 10, and 11 carry the honesty rule as 'Kill (not yet built)' - the instruments are in print but the item-level joins are not yet datasets.
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The single-custodial-line structure is established diplomatic doctrine - no royal registry or central archive, preservation through the beneficiary house's muniments (Chaplais on the chancery's lack of archive, Keynes on the preservation of diplomas) - and cross-archive duplicate transmission is known to be exceptional; but the overlap share itself (items with medieval witnesses in two or more distinct archives, pinned at 0.003-0.05) has never been computed over the catalogue's manuscript fields. The redundancy-geometry census is the new instrument; w15-004's capture-recapture territory is distinct and untouched.
