Procedural generation:
Grid generator creates WxH rooms with cardinal exits
Seeded-random description selection (deterministic)
Density parameter controls connectivity (0.0-1.0)
Edge ports for wiring grid to external rooms
forest_area.yaml — 7 description variants
street_grid.yaml — 5 description variants
Verify command (executor.py verify):
Connects to live game, checks rooms match spec
Validates names, descriptions, attributes against state
Reports discrepancies
Rollback command (executor.py rollback):
Destroys objects in reverse order (exits first, then rooms)
Clears state file after destruction
Dry-run mode supported
Thing support:
Thing model (name, location, description, flags, attrs, parent)
Parsed from spec YAML and component definitions
Compiled to @create + @desc + &attr + @parent commands
Shown in plan output
Component things expand with parameter substitution
New components:
tavern.yaml — 3 rooms + barkeeper NPC thing
street_grid.yaml — procedural city block grid
Test specs:
town.yaml — combines tavern + street_grid + manual rooms/things
forest.yaml — 4x4 procedural forest with edge connection
Zone support:
@chzone emitted in compiler for all rooms
@parent emitted when room has parent field
All 4 test specs pass DRC.
