a panic in a session task now kills that connection, tokio catches it and the
accept loop carries on. with abort it took the whole server down.
the data table RwLock is std so it poisons on panic, and every lookup went
through expect(). one panic would have bricked every later table read, which is
worse than the abort was. it reads the inner value now, the table is read only
once installed.
RandomSpells / DifferentSpells / RareChance / EpicChance / MinGold / MaxGold all
come off the chest row now, gold is scaled by the player's arena. magic chest is
30 cards over 8 cards with 1 epic and 6 rares, like the client says it is.
arena chest rows inherit everything through BaseChest, so Free_Arena1 reads Free.
500 LogicSwapSpellsCommand does the real work, 520 and 521 are no-ops in this
build so they just decode. 535 puts its data reference BEFORE the base header,
unlike every other command.
collection only shrinks when a card moves into an empty deck slot, that is the
one case where the home checksum moves.
rounding is banded and the 5s band biases +3, so 22 goes to 25 not 20. numbers match the csv for arena 1 and 2.
free chest end timestamp needs migration 0002.
if the client presents an id we don't know, create it under that id and bump the sequence past it.
also chest offers match through BaseChest, so one silver row covers every arena.
json stores are gone, they nulled out every data ref on load and wrote the null straight back on save.
shop json and the purchase commands ended up in here too.
