Changelog

Version: 1.1.0
Date: 2026-09-03
  Changes:
    - In response to user requests, Ghost Combinator technology now requires Construction robotics 
      and Circuit network instead of Logistic system and Production science pack. The combinator 
      is avaialble earlier.
    - Research cost is now derived from those two prerequisites: every science pack either of
      them needs, at the higher amount, for the higher of their cycle counts
      and times. The cost is recalculated after all other mods load, so overhaul mods that re-cost
      Construction robotics or Circuit network should carry this technology along with them.
  Bug Fixes:
    - The combinator window has had padding add
    - The mod no longer fails to load if another mod removes one of its prerequisite
      technologies.

Version: 1.0.0
Date: 2026-08-15
  Features:
    - Added an output mode selector. Each combinator now reports one kind of construction
      demand: Builds (entity ghosts), Tiles (tile ghosts) or Upgrades (upgrade planner
      requests). To see more than one at once, place several combinators and wire their
      outputs together - the circuit network adds the signals.
    - Tile ghosts are now tracked: landfill, concrete and its variants, stone brick, space
      platform foundation, and the Space Age soils.
    - Upgrade requests are now tracked, reported as the target item.
  Bug Fixes:
    - Combinators built by a space platform were never registered and output nothing.
    - Entities whose placing item differs from their name reported an invalid signal
      (stone brick tiles reported "stone-path", which is not an item).
    - Surface data for deleted surfaces is now discarded instead of accumulating.
  Changes:
    - Existing saves are rebuilt from a one-time full surface scan on update. This also
      picks up ghosts placed before the mod was installed, which were never counted before.
      All existing combinators keep their current behaviour (Builds mode).
    - Added /gc-rescan to rebuild tracking on demand.
