-- Every story/event flag a mod can watch has to travel through

-- src/script/Flags.lua, which is what emits flag.changed. The overworld used
|
|
-- to write nine of them straight into save.flags -- card-key doors, defeated
|
|
-- trainer events, victory items and rewards, the two gate guards, a Seafoam
|
|
-- boulder and a warp-origin battle -- so a mod listening for the beat never
|
|
-- heard it. A behaviour check plus a guard against writing raw again.
