* Background triggers are delivered AT LEAST ONCE, so a redelivery of the same event would

|

|

* writes the marker and returns true; a redelivery finds it present and returns false, so the
|

* caller skips. Claim right before sending — a suppressed (quiet-hours / opted-out) notification
|
||
|
|
* should not burn a claim.
|

|
|
*

* Fail-OPEN: if create() fails for any reason OTHER than "already claimed", return true and let
|

|
|
* the notification proceed. A rare duplicate is better UX than a silently dropped ping, and it
|
||
|
|
* keeps an infra blip on the marker write from swallowing every notification. The trade this makes
|
||
|
|
* explicit: at-least-once → at-most-once (a send failure AFTER the claim drops that one push).
