wtclaude	2d2a68d4a7	docs(android): note the empty-subscriptions PUT serialization gotcha Record the "can't turn off the last notification" class of bug in PLAN.md §11: the PUT /auth/me/notifications/subscriptions validator requires `streams`, so an empty set must serialize as {"streams":[]} not {}. kotlinx.serialization drops a property equal to its default (encodeDefaults=false), so a request DTO field defaulting to emptyList() gets omitted when empty and the server rejects it 400. Generalized to any "replace the full set" PUT/POST whose empty value equals a DTO default. Documents the fix in Android-app fix/notifications-empty-subscriptions.

docs(android): note the empty-subscriptions PUT serialization gotcha

Record the "can't turn off the last notification" class of bug in PLAN.md §11:
the PUT /auth/me/notifications/subscriptions validator requires `streams`, so an
empty set must serialize as {"streams":[]} not {}. kotlinx.serialization drops a
property equal to its default (encodeDefaults=false), so a request DTO field
defaulting to emptyList() gets omitted when empty and the server rejects it 400.
Generalized to any "replace the full set" PUT/POST whose empty value equals a DTO
default. Documents the fix in Android-app fix/notifications-empty-subscriptions.
