WORLD / EVIDENCE-SCOPE MAP
A geographic discovery layer over five exact BEDU evidence scopes. The map shows where the current graph has documented associations; it does not describe how whole populations sleep.
STATIC FALLBACK / ALL MAPPED NODES
The numbered list is the authoritative discovery fallback. The schematic plane above is presentation only and carries no additional geographic claim.
Region scope / GB-ENG
A regional node used for documented English bed objects and design history.
Four-poster bed → England
The current England link comes from a documented English historic four-poster example. It does not make four-poster beds exclusively English.
Country scope / FR
A region node used for French furniture-history associations and museum examples.
Sleigh bed → France
The current France link records documented French-form/design-history context for a sleigh-bed association. It does not claim exclusive invention or use.
Country scope / US
A region node used for U.S.-specific bed examples, standards, and regulations.
Bunk bed — U.S. regulatory seed → United States
The current United States link is jurisdictional: a U.S. federal bunk-bed regulatory seed. It does not describe cultural prevalence, origin, or uniquely American use.
Country scope / IN
A country-level culture/region node used for India-specific charpoy evidence. Broader South Asian distribution is intentionally not inferred from the current seed sources.
Charpoy → India
Current charpoy evidence in BEDU is India-specific. BEDU010 does not infer all-South-Asia distribution from these sources.
Country scope / JP
A culture/region node for Japanese sleeping-space and furniture relationships.
Japanese futon floor system → Japan
The current source links futon floor sleeping with a traditional Japanese room context. BEDU010 does not claim universal household practice across Japan.
SEMANTICS / DO NOT COLLAPSE
BEDU keeps geographic scope separate from what a relationship actually means. A current regulation, a historic object example, and cultural documentary evidence are not interchangeable.
A source documents a bed form in a country-specific cultural, room, furniture-history, or documentary context. This does not establish universal practice, exclusivity, origin, or prevalence.
A source ties a documented historic example or place-specific historical object context to a geographic scope. This is not automatically an origin or distribution claim.
A current rule or guidance source applies in a jurisdiction. It says nothing by itself about cultural preference, prevalence, origin, or typical household use.
Used by BEDU023+ historic-object records when an object source independently supports a role-specific location. These assertions never reuse generic bed-form geography as object location proof.
ARCHITECTURE / FUTURE SCALE
Future BEDU can add sourced historic places, maker locations, and object provenance without changing the semantics of the five current country/region nodes.
BOUNDARIES / EXACT SCOPE
The map is a discovery interface over stored claims, not an ethnographic distribution map.
Map position is presentation only, not geospatial evidence.
A mapped association is not a claim about prevalence, origin, exclusivity, or universal practice.
India-specific evidence remains India-specific; Japan-specific evidence remains Japan-specific.
The U.S. bunk-bed node is regulatory jurisdiction, not cultural prevalence.
England remains a region-level scope; BEDU does not silently broaden it to the United Kingdom.
Object-location provenance is used only by independently sourced historic-object records; generic bed-form geography never becomes object creation, holding, historical-use, or provenance proof.
OBJECT PROVENANCE / INDEPENDENTLY SOURCED
7 role-specific object-location assertions use the reserved object-location-provenance meaning. They do not reuse generic bed-form geography as object proof.
1590–1600 (constructed around 1590) / Documented object form
A monumental English four-poster bed constructed around 1590 and documented by the Victoria and Albert Museum; BEDU records the museum-supported object facts separately from broader four-poster history.
1760–90 / Documented object form
A cherry daybed in The Metropolitan Museum of Art, made in Connecticut and dated 1760–90; the object record combines Philadelphia- and Connecticut-associated craftsmanship while declining an unsupported maker attribution.
1841 / Contextual design-history link
A documented 1841 D. Phyfe & Sons Grecian bedstead made for the Millford furnishing program and now in The Metropolitan Museum of Art; BEDU links it to sleigh-bed history only as contextual design evidence, not as a title equivalence.
ICU / CONNECTED DISCOVERY
These links come from ICU's bounded public recommendation graph. Bed-size market scope, compatibility authority, fit geometry, history, and evidence boundaries remain unchanged.
