Expand 1450 checkpoint: Korea mining colony, Burgundy strategy, detailed state surveys

Korea: upgraded from tributary to resource colony (Musan iron, coal, gold)
- Song mining concessions in northern Korea, economic colonization pattern
- Korean + Australian iron ore as future competitors to Song domestic industry

Burgundy: survival strategy defined
- Lorraine (French-speaking) as primary expansion target
- Savoy as secondary target for Mediterranean corridor
- "True France" Capetian legitimacy narrative, Piedmont-Sardinia parallel

Additional 1450 details:
- Plantagenet France: English nationalism stirring on neglected islands
- Castile: falling behind neighbors, strategic stagnation
- Khoqand: cultural golden age (Ulugh Beg), geographically squeezed
- Hungary: approaching second cold wave agricultural crisis
- Poland/Byzantium: quietly gaining autonomy as Great Khanate weakens
- Printing press: accelerating reform movement across Catholic Europe

 - But no external threat → less motivation for centralization or technology adoption
 - V3 era: pre-industrial but wealthy from silver, capable of rapid industrialization if stimulated (Black Ships equivalent scenario)
 
-### Korea (Goryeo): Song Tributary
+### Korea: From Tributary to Resource Colony
 - Mongol Khanate cannot reach Korea (Song controls southern Manchuria, blocks land approach)
-- Korea defaults to traditional tributary relationship with Chinese dynasty (Song)
-- Purchases Song industrial goods, maintains internal autonomy
-- Culturally influenced by Song but politically independent
+- Nominally: traditional tributary relationship with Song. Actually: increasingly a satellite state / resource colony.
+- **Korean mineral wealth drives Song's tightening grip**:
+  - Northern Korea: Musan iron mine (one of Asia's largest), extensive anthracite coal, Unsan gold deposits, copper/lead/zinc
+  - Southern Korea: some gold/silver, tungsten
+  - Non-mineral: ginseng (extremely high-value trade good)
+- **Iron + coal in northern Korea** = the two essential industrial raw materials, directly adjacent to Song's Manchurian industrial zone
+- Song mining companies establish "special concession zones" in northern Korea → profits flow to Song
+- Korean king retains nominal throne but has no control over mining regions
+- Korean handicraft industry destroyed by Song industrial imports (same pattern as India, but more thorough due to proximity)
+- By V3 era: nominally independent Song vassal, actually an economic colony. Mining sector controlled by Song capital. Similar to vanilla V3's semi-civilized nations under great power economic penetration.
+- **Korean iron ore + Australian iron ore (later)** both compete with Song's domestic northern iron industry → additional pressure on Song's North-South economic tensions

 ### Great Khanate: Temporary Stabilization
 - Kazakhstan recovery provides some economic/territorial boost
 - Agricultural serfdom system in Ukraine/Hungary deepening
+- Hungary: second cold wave approaching → crop failures will cause landlord-serf tensions to spike
+- Northern Ulus gaining de facto autonomy through military credentials (Finnish war)
+- Poland: quietly expanding self-governance while Great Khanate is distracted
+- Byzantium: also gaining autonomy as overlord weakens
 - But fundamental problems unresolved: no industrialization, internal ethnic fractures, trade isolation
 - The Kazakhstan campaign bought time but didn't solve anything
 
+### Burgundy: Survival Diplomacy and Expansion
+- **Geopolitical trap**: Landlocked, no coastline, no natural defenses, surrounded by larger powers
+- **Diplomatic balancing**: Allied with Germany (vs. France) + friendly with Aragon (vs. Germany). Playing all sides.
+- **"True France" narrative**: Capetian blood → claims to be the legitimate French successor vs. Plantagenet "usurpers." Attracts French-speaking intellectuals/artists fleeing Plantagenet control. Dijon as cultural capital of the French-speaking world.
+- **Expansion target: Lorraine (western, French-speaking parts)**
+  - Western Lorraine is French-speaking but not part of Greater Germany (German ethnic nationalism excludes it)
+  - Nor firmly under Plantagenet France
+  - Small, weak, a natural buffer zone → Burgundy absorbs it
+  - Provides strategic depth against France and connection toward the Rhine
+- **Secondary target: Savoy (French-speaking western parts)**
+  - Savoy duchy straddles Alps, western part is French-speaking
+  - Gives Burgundy a corridor toward Italy/Mediterranean
+  - But risks conflict with Aragon (if Aragon claims Provence) or Germany (if Savoy is German-aligned)
+- **Historical parallel**: Piedmont-Sardinia — small state surviving through agile diplomacy, positioned to eventually lead a larger unification movement (in this case, French-speaking peoples)
+- V3 role: scrappy mid-tier power with "unite the Francophone world" potential event chain
+
+### Plantagenet France: Island Tensions
+- Scottish campaign: prolonged Highland guerrilla resistance, Lowlands occupied
+- Ireland: Pale expanding but Gaelic interior unconquered
+- **Emerging problem**: English-speaking island population ruled by French-speaking Paris court for 200+ years. English nationalism beginning to stir — "taxation without representation" dynamic. Island elites marginalized from continental politics. Seeds of future English separatism.
+
+### Castile: Falling Behind
+- Pedro I's line continues: tolerant of Jews/Muslims, Granada survives comfortably
+- But **strategically stagnant**: Portugal expanding in Atlantic, Aragon dominating Mediterranean, Germany industrializing
+- Castile is a large inland agricultural kingdom with no clear expansion direction
+- May begin Atlantic exploration ~1470s-1490s but a generation behind Portugal
+- Potential for internal pressure: "why are we falling behind our neighbors?"
+
+### Khoqand Khanate (Timurid Remnant)
+- Samarkand/Bukhara cultural golden age (Ulugh Beg's observatory, astronomy, architecture)
+- Squeezed between Great Khanate (north) and Ilkhanate (south) but Silk Road still passes through → wealthy
+- Cultural prestige compensates for military vulnerability
+
+### Printing Press in Europe (~1440s)
+- Song invented movable type printing ~1040s, 400 years earlier
+- Song printing technology may have influenced European development via Silk Road
+- Regardless of origin: European printing press spreads rapidly ~1440s+
+- **Accelerates Hussite/reform movement**: pamphlets, vernacular Bibles, reform literature mass-produced
+- Reform ideas spreading faster than Papacy can suppress them
+
 ### Ilkhanate: Industrialization Advancing
 - Post-Timur expansion (Khorasan, western Afghanistan) consolidated
 - Persian bureaucracy driving economic modernization
