Message budgets: master DB vs L5 card machine
Extend L5
RECOMMENDED
- Status
- RECOMMENDED — awaiting Vinayak
- Options
- Extend L5 as the budget/suppression owner; or a separate master message DB that L5 consumes
- Trade-offs
- Consolidation vs new store
- Recommendation
- Extend L5 as the owner of message budgets, suppression and disposition. No separate message database.
- Why
- L5 already owns the card machine and the sender. A second store would need syncing.
- Evidence
- E24 (ISA-18.2); E15 (alarm-load context); C20, C47.
- Reversible
- Split later only if message volume forces it.
- Blocks
- Message governance, D7.
