history

Second ingest into the history thread. Three-round autoresearch synthesis of the causes of the Western Roman collapse — anchored by Grokipedia's Fall_of_the_Western_Roman_Empire page (the first autoresearch run with the new grokipedia-fetch anchor step wired into /autoresearch).

• Created peter-heather (entity, person): the dominant post-2000 "external pressure" theorist; "Newton's Third Law" framing.
• Created bryan-ward-perkins (entity, person): catastrophist on material decline; emphasizes contingency over structural inevitability vs Heather.
• Created kyle-harper (entity, person): the climate-and-disease catastrophist; thesis substantially scaled back by 2024 modeling.
• Created walter-goffart (entity, person): transformation-school leader. Page flags a research gap: Goffart's affirmative case is reconstructed from critics, not directly from his writing (Penn Press URL 403'd; Wikipedia historiography article omitted him).
• Created majorian (entity, person): Western Emperor 457–461; central case study in contingency-view of the collapse.
• Created west-east-divergence-by-geography (concept): A.H.M. Jones / Heather / Ward-Perkins convergent finding that geography (not institutions) explains why only the West fell.
• Created transformation-versus-collapse (concept): the central historiographical debate; current weight of evidence on the catastrophist side for the West.
• Created antonine-plague (concept): the 165–180 CE pandemic; mortality cut from ~20% to ~7% by 2024 PLOS One modeling.
• Created late-antique-little-ice-age (concept): 536–660 climate event; timing rules it out as a Western-collapse cause.
• Created mechanism external-pressure-to-western-roman-collapse (5 steps, 13 citations): Persia stretch → Germanic + Hunnic migration → territorial cascade → contingent failure of Majorian's recovery → 476. Conviction medium-high. Written via _lib/causal_extract.py write-mechanism.
• Created was-the-western-roman-fall-inevitable-or-contingent (question): the Heather-vs-Ward-Perkins axis on structural inevitability vs contingency.
• Created was-the-antonine-plague-a-structural-shock (question): the historian-vs-epidemiologist methodological gap that the 2024 PLOS modeling exposes.
• Updated index.md: added 5 entities, 4 concepts, 1 mechanism, 2 questions, 1 source.

Non-contradictions with the LBA ingest. Both ingests file civilization-collapse mechanisms but the historical events are distinct; cross-linking between lba-multi-stressor-collapse-chain and external-pressure-to-western-roman-collapse as "similar meta-patterns" is deferred — that's a synthesis call for the user.

Open research gap. Goffart's affirmative case is the one gap from the autoresearch pass that a future ingest should close. A direct fetch of Barbarian Tides (2006) or Barbarians and Romans 418–584 (1980) would substantially strengthen walter-goffart and transformation-versus-collapse.

First ingest into the history thread. Three-round autoresearch synthesis of the Late Bronze Age Collapse — scholarly consensus on multi-stressor framing, Millek's destruction-scale revisionism, Cline's 2024 adaptive-cycle sequel.

• Created eric-cline (entity, person): central popularizer of the multi-stressor LBA collapse framing.
• Created jesse-millek (entity, person): destruction-horizon revisionist; 61% of claimed LBA destructions misdated/false per his 2023 audit.
• Created late-bronze-age-collapse (concept): the event itself; geographic + temporal scope, civilizations affected, scale-of-collapse revision.
• Created sea-peoples (concept): reframed from cause to symptom; named groups in Merneptah and Ramses III inscriptions.
• Created mechanism lba-multi-stressor-collapse-chain (5 steps, multi-citation): climate → famine → trade collapse → migration → differential systems collapse. Conviction medium-high.
• Created were-lba-destructions-synchronous-or-sequential (question): the synchronicity-vs-sequence debate that gates which causal frame is most explanatory.
• Updated index.md: added all new entries.
