# [DEF:ADR-0007:ADR]
# @STATUS REJECTED
# @PURPOSE Document the decision to forbid `fromStore` + multiple `$derived` in Svelte 5 components due to infinite reactive flush loop.
# @RELATION DEPENDS_ON -> [ADR-0006:ADR]
# @RATIONALE fromStore(store) returns a reactive object with .current property. Using it with multiple $derived creates persistent render_effect instances on every reactive re-evaluation, leading to an infinite flush loop and 100% CPU usage after ~300 poll cycles.
# @REJECTED fromStore with multiple $derived in the same component — causes infinite reactive flush loop in Svelte 5 runtime.
