 ### High-Level AI / Delegation
 
-- Faction AI now acts at a strategic level instead of directly micromanaging every ship.
+- Faction AI now acts at a strategic level and issues direct orders to ships.
 - Empire AI chooses high-level goals such as:
   - secure home and mining space
   - contest central systems
-  - assign industrial fleets to mining loops
-- Pirate AI chooses raid targets and dispatches fleets into hostile space.
-- Fleet-level orders are now the intended command boundary between:
-  - faction strategy
-  - fleet / wing execution
-- This work was specifically done to stop faction AI from stomping `screen` behavior with raw ship move orders.

-### Fleets / Wings
-
-- Fleet creation now groups ships per faction and role in `src/game/fleet/runtime.ts`.
-- War fleets and industry fleets are generated from faction-owned ships.
-- Wing behaviors remain meaningful at the tactical layer.
-- `screen` is intended to remain subordinate to fleet command rather than independent faction micromanagement.

 - Economic logistics are still abstracted heavily.
 - Ship construction is recipe-gated but still simplified.
 - Stations consume pooled faction stock rather than explicit transport delivery chains.
-- Fleet window remains useful, but the overall UI is now only partially refit for observer mode.
+- Bootstrap progression is still constrained by the current station recipe / stock model.
+- The ships window is useful for inspection, but the overall UI is still only partially refit for observer mode.
 - There is still no persistence layer for window layouts, saves, or generated universe seeds.
 
 ## Suggested Next Steps
 
 - Extract faction strategy into a dedicated AI / planning module
-- Extract fleet order execution into its own gameplay system
 - Separate economic simulation from UI and rendering concerns
 - Improve transport logistics so goods physically move through faction supply chains
 - Add explicit shipyard construction queues and faction production priorities
-- Improve combat behavior so `screen`, `escort`, and `command` have stronger distinct tactical roles
+- Rework bootstrap progression so factions can genuinely grow from near-zero infrastructure
 - Add system-level threat, ownership, and economy views for game-master inspection
 - Add save/load support for generated universes and long-running simulations
