 - Post-Hanzhong-rain camp events with Li Yan, Huang Quan, Jiang Wei, Wang Ping, Zhuge Liang, Wei Yan, and Ma Liang focusing on rain-delay ledgers, return-first road markings, restrained counterattack limits, and the next northern-front recalculation
 - Sixty-second battle Qishan renewed offensive route, where the preserved Hanzhong and Wudu/Yinping supply roads turn back into an attack decision, forcing nine recommended officers into seven slots across a 124x106 battlefield while Zhuge Liang pressures Sima Yi's delay line, Zhang He's pursuit, Guo Huai's flank block, and Lucheng-front villages
 - Post-Qishan-renewed camp events with Jiang Wei, Wei Yan, Zhao Yun, Wang Ping, Huang Quan, Ma Liang, Li Yan, and Ma Dai focusing on breakthrough limits, return markers, village proclamations, and the next deeper northern-front calculation
+- Sixty-third battle Lucheng pursuit route, sixty-fourth battle Weishui camps route, and sixty-fifth battle Weishui north-bank pressure route extend the northern-front push into Sima Yi's delay line while keeping Zhuge Liang-led seven-officer sortie tradeoffs active
+- Sixty-sixth battle Wuzhang finale closes the current campaign with a 132x114 final battlefield, Sima Yi/Zhang He/Guo Huai objectives, Wuzhang aftermath camp events, Jiang Wei inheritance framing, and final epilogue transition into the ending scene
+- Unit spritesheet loading is now deferred until each battle needs the selected texture set, while story backgrounds and battle maps continue to lazy-load per scene

 ## Next Steps
 
-1. Build the next northern-front step after Qishan renewed offensive, turning the pressure on Sima Yi's delay line into the next deeper northern campaign choice without treating the successful push as an ending
-2. Expand post-Baidi and post-Nanzhong camp consequences with grief checks, recovery policy choices, village reassurance, captive handling, and regency decisions that affect sortie recommendations
-3. Expand reserve planning into individual officer assignments, including targeted class practice, paired bond training, and camp task slots
-4. Add a dedicated treasure/equipment management view so players can compare special effects and growth
-5. Keep expanding scenarios through the long campaign instead of treating the current slice as an ending
+1. Polish the final ending presentation with a dedicated Wuzhang/Jiang Wei visual if a new original story background is commissioned
+2. Expand reserve planning into individual officer assignments, including targeted class practice, paired bond training, and camp task slots
+3. Add a dedicated treasure/equipment management view so players can compare special effects and growth
+4. Consider a later "season two" Jiang Wei northern-campaign arc only after the Liu Bei/Zhuge Liang campaign ending is stable
