Sub-claim "Idempotency keys allow the same operation to be applied mult…": 60% covered by S8 — S8 directly states that an idempotency key ensures a retried request is processed at most once, covering the core mechanism. However, it does not explicitly mention replicated systems or retries due to replication.
Sub-claim "In replicated systems, network partitions or leader changes …": 20% covered by S8 — S8 mentions preventing double-charging on retries but does not discuss network partitions, leader changes, or duplicate messages in replicated systems, so coverage is minimal.
Sub-claim "The use of idempotency keys implies that replication is asyn…": 20% covered by S8 — S8 notes that clients supply nonce keys to prevent double-charging, but it does not discuss replication semantics such as asynchronous or at-least-once delivery.
The only relevant source (S8) covers the basic idempotency concept but lacks specific replication details. None of the skipped sources address idempotency keys or replication, so purchasing them would not improve coverage.
Final check — "Idempotency keys allow the same operation to be applied mult…": 50% assessed by S8
Final check — "In replicated systems, network partitions or leader changes …": 0% assessed
Final check — "The use of idempotency keys implies that replication is asyn…": 20% assessed by S8
Final coverage assessment — The only relevant source (S8) explains the basic function of idempotency keys — preventing duplicate processing on retries — but it never discusses replication, network partitions, leader changes, or the implied replication semantics. Therefore the sub-claims about what idempotency keys reveal about replication are largely unsupported.

The phrase "Idempotency keys prevent double-spends" reveals that in replicated systems, retries or duplicate messages can occur due to network partitions or leader changes, and idempotency keys ensure only one logical transaction is committed, which is essential when an autonomous agent issues many rapid payments. This implies that replication may be asynchronous or at-least-once, requiring clients to supply unique keys to make the system safe under re-execution.
Evidence ledger — quotes verified before rewards
Idempotency keys allow the same operation to be applied multiple times without causing duplicate effects, which is essential when replicated systems may retry or duplicate requests.
