+**Current Follow-Up Priorities:**
+- Teach the Shardok AI when to use the Warden evacuation command. The command is valuable when the Warden's side has
+  captured enemy heroes and can secure them by leaving the battle, especially when the battle outcome is uncertain or
+  trending against that side.
+- Add the strategic passive custody bonus: each round, prisoners in a province guarded by a ruling-faction Warden should
+  get a small accumulated positive bias toward joining that faction. Prefer storing this as an addition to the existing
+  `factionBiases` entry rather than changing the global `roundsInType` multiplier, so the bonus only reflects rounds
+  actually spent under Warden custody.
+- Make tactical AI more protective of heroes at risk of capture when a Warden may be present. Warden evacuation makes
+  captured heroes harder to recover, so the AI should treat exposing high-value heroes to capture as more dangerous than
+  before. This matters even when the AI does not have perfect knowledge that a Warden is in the battle.
