Benin Iya named gate-route system inferon

Epistemic status

Inferred L3 evidence-packet article.

This article describes an entity that is not directly attested. It is an inference from the evidence listed below.

Summary

Inferon for the Benin Iya gate system as a partly lost, tradition-preserved access and route structure.

What is being inferred

This inferon's inferred object is a named gate-route system within the Benin Iya earthworks: the claim is that the nine-gate tradition corresponds to real, locatable points along the earthwork network, even though most of the physical gate structures no longer survive to be inspected directly. The claim stays at the level of "a named route system existed and is partly locatable," not a claim about the exact position or condition of any specific gate.

What is attested

• Evidence 2078 records: The article discusses the Benin Iya system, a tradition of nine gates, the loss of visible gate structures, and a likely surviving or locatable gate near Okedo or Ikpoba.
• Evidence 2079 records: The UNESCO page treats Benin Iya and Sungbo's Eredo as vast community earthwork clusters and dates larger enclosures up to around the fifteenth century.
• Evidence 2080 records: NASA describes the Iya as interlocking earthworks with ramparts and ditches visible in satellite imagery, built over centuries as defensive, political, and economic boundaries.
• Evidence 2081 records: The Met summary describes inner and outer rings around the royal precinct and nine manned gates serving access, protection, and ritual functions.
• Evidence 2082 records: The page preserves named and route-linked traditions for the nine gateways, but it is used only as low-authority lead context.
• Evidence 3526 records: Offline judge treated existing inferon 275 (missing_relation) as support for Benin Iya named gate-route system inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1480.

Why infer this entity

The physical case rests on two independent observation types: Evidence 2080, NASA Earth Observatory satellite imagery, shows the interlocking ramparts and ditches as centuries-long defensive and economic boundaries, and Evidence 2078, the archaeology-focused article, argues a surviving or locatable gate near Okedo or Ikpoba specifically, which is the strongest single claim in the packet for the named-route inference. The Metropolitan Museum's heritage summary (Evidence 2081) supports the nine-gate structure functionally, describing access, protection, and ritual roles for inner and outer rings, and UNESCO's Tentative List entry (Evidence 2079) supplies bibliographic-control dating for the larger enclosures without itself confirming gate locations. Evidence 2082, the Edo World local-tradition page, preserves the named gate traditions that give the system its route names, but it is used only as lead context because a community heritage page cannot carry the same evidential weight as a satellite record or an archaeological account. The packet has no counterevidence item; nothing here challenges the gate-route reading, so that absence is recorded rather than read as reinforcing the claim.

Evidence ledger

• Evidence 2078: Archaeology article on Benin Iya and gate survival, archaeology PDF. The article discusses the Benin Iya system, a tradition of nine gates, the loss of visible gate structures, and a likely surviving or locatable gate near Okedo or Ikpoba. Role: Supporting evidence.
• Evidence 2079: UNESCO Tentative List, Benin Iya and Sungbo's Eredo, tentative list. The UNESCO page treats Benin Iya and Sungbo's Eredo as vast community earthwork clusters and dates larger enclosures up to around the fifteenth century. Role: Bibliographic control.
• Evidence 2080: NASA Earth Observatory, A Glimpse of History in Benin City, Earth Observatory article. NASA describes the Iya as interlocking earthworks with ramparts and ditches visible in satellite imagery, built over centuries as defensive, political, and economic boundaries. Role: Supporting evidence.
• Evidence 2081: Metropolitan Museum perspective on Benin City earthworks, heritage summary. The Met summary describes inner and outer rings around the royal precinct and nine manned gates serving access, protection, and ritual functions. Role: Supporting evidence.
• Evidence 2082: Edo World, The Ancient Nine Gates of Benin, local tradition page. The page preserves named and route-linked traditions for the nine gateways, but it is used only as low-authority lead context. Role: Lead context.
• Evidence 3526: Offline existing-inferon judge ledger control source, existing_inferon_judge_promote:inferon:275. Offline judge treated existing inferon 275 (missing_relation) as support for Benin Iya named gate-route system inferon. Evidence strength: bounded but below-publication structural/source inferon; sufficient for L2 review, not for article promotion. The accountable path is EvidencePath 1480. Role: Noetic interpretation.

Counterarguments

• The packet contains no separate counterevidence item; this absence does not remove the need for challenge.

Confidence scores

• Direct attestation: 15
• Existence warrant: 76
• Specificity confidence: 58
• Reconstruction dependence: 70
• Counterevidence pressure: 0

What would change the score

• A direct attestation would move this out of the inferred catalogue.
• Stronger independent evidence would raise the warrant or specificity.
• Better counterevidence would lower the warrant or force retirement.
