== v0.36.55 — Under The Hood: The Save-sync Rules, Written Down ==
* Groundwork, with nothing to see in game. The rules that decide when your save is written, when it is sent to the cloud, and what happens when you switch devices were spread across the code as a set of flags. They are now one place with tests around them — including a test for each of the five save-sync problems reported in the past, so none of them can come back unnoticed.
* No change to gameplay, progress, balance or your save.
* The sync journal in Settings now stamps each line with the game version that wrote it — so if you ever send a screenshot of it, it says which build produced what.
* Part 2: the game now actually uses those rules. The eight scattered flags that used to coordinate saving and syncing are gone, replaced by the single tested component. Behaviour is deliberately unchanged — this is groundwork so the next fix in this area lands somewhere provable.
