Distributed Systems Notes article title exactly matches the question. Cached and free, high historical citation rate (39%) and reputation (37/100) for this subject.
Ethereum Foundation Blog covers AI agents in protocol security, tangentially related but not directly about idempotency or replication semantics.
Stripe Blog article is about payment disputes, not the distributed systems theory of idempotency or replication. Price is low but topical fit is weak.
Vitalik's blog discusses DeFi and Ethereum search, not the specific replication semantics of idempotency keys.
Cointelegraph article is about crypto regulation in Thailand, not replication or idempotency.

Reused cached Distributed Systems Notes — Idempotency keys prevent double-spends (free) — S1
Sub-claim "Replication may apply the same operation multiple times, so …": 20% covered by S1 — S1 explains that idempotency keys prevent charging twice on client retries, but it does not mention replication or replicas applying operations multiple times.
Sub-claim "Replicated systems often provide at-least-once semantics, an…": 30% covered by S1 — S1 says a retried request is processed at most once, which is related to exactly-once effects, but it does not discuss replication or at-least-once semantics.
Sub-claim "The use of idempotency keys implies that replicas must coord…": 0% covered — S1 does not address coordination or storage of idempotency keys by replicas; no gathered source covers this.
All subclaims are poorly covered because the only gathered source discusses idempotency keys in payment retries without linking them to replication. The skipped sources are largely unrelated to distributed systems, replication, or idempotency, so none would fill the gap; buying more would waste budget.
Final check — "Replication may apply the same operation multiple times, so …": 30% assessed by S1
Final check — "Replicated systems often provide at-least-once semantics, an…": 30% assessed by S1
Final check — "The use of idempotency keys implies that replicas must coord…": 10% assessed by S1
Final coverage assessment — The gathered evidence explains idempotency keys in the context of client retries preventing double charges, but it does not discuss replication, replica coordination, or at-least-once semantics in replicated systems. Therefore, it does not sufficiently reveal how idempotency keys relate to replication.

Payouts to cited creators appear here.
The provided source does not support any of the subclaims about replication. It states that an idempotency key ensures a retried request is processed at most once and prevents double-charging when a client retries after a timeout, but it makes no mention of replication, replicas, or at-least-once semantics.
Evidence ledger — quotes verified before rewards
Replication may apply the same operation multiple times, so idempotency keys ensure duplicates do not cause double-spends.
0%No reward-qualifying evidence
Replicated systems often provide at-least-once semantics, and idempotency keys enable exactly-once effects for clients.
0%No reward-qualifying evidence
The use of idempotency keys implies that replicas must coordinate or store keys to deduplicate repeated writes.
