01must proveProposed | Charged usage reaching 80% or 100% records one crossing for that threshold and month despite concurrent settlements; held credits do not create crossings. | lifecycle | service, database | observed |
02must proveProposed | Threshold evaluation uses whole-number arithmetic over charged credits and allowance including currently active additional capacity. | calculation | service | observed |
03must proveProposed | Each active holder of the organization’s built-in Administrator role receives one notice, excluding suspended holders, other staff and administrators of other organizations. | policy | service | test |
04must proveProposed | The warning provides used, allowed and remaining credits, the local reset date, the 100% consequence and support contact; the pause notice names the reset date and shares the customer pause wording. | calculation | service | observed |
05must proveProposed | An unsent crossing can be claimed only below three attempts and outside a ten-minute live claim, giving racing senders one delivery owner. | invariant | service, database | observed |
06must proveProposed | Settlement sends only after its own transaction commits; an enclosing open transaction leaves the notice pending for reconciliation. | policy | service | test |
07must proveProposed | Zero successful deliveries leave the crossing unstamped for hourly retry up to three attempts; partial success stamps the successful-recipient count, and three failures leave an unresolved crossing. | lifecycle | service, database | observed |
08must proveProposed | A crossing without administrator recipients is stamped with zero recipients and logged as a warning without further retries. | policy | service | observed |
09Proposed | Nonproduction email delivery follows the test-mailbox and allow-list policy, and environment-withheld messages count as handled. | policy | service | documented |
10Proposed | Corrections and allowance reductions do not trigger threshold notices even when they move usage beyond a threshold. | policy | service | documented |
11Proposed | Notice failures contribute a metric whose alarm triggers above three failures in fifteen minutes. | policy | service | documented |
12must proveProposed | A notice is delivered before its completion stamp is saved. If processing stops between those actions, a later attempt can deliver the same crossing again. | lifecycle | service | observed |
