|

|
* The `date_matches` collection is server-write-only — Firestore rules deny all
|

|
|
* client writes (`allow create, update, delete: if false`). This trigger is
|
||
|
|
* therefore the single source of truth for match creation. The client only

|
* records swipes and observes `date_matches` for the result.
|
||
|
|
*
|
||
|
|
* Idempotency: the match document id is the date idea id and creation runs in a
|
||
|
|
* transaction, so repeated swipes on the same idea and concurrent invocations
|
||
|
|
* never produce a duplicate match.
