About same-queue vs separate retry queue mechanics; not about duplicate email side effects or provider dedupe. - free public original-page READ selection (not a cache hit); no purchase or creator reward.

Article on BullMQ retries, idempotency and failure modes; preview mentions naturally idempotent operations, likely covering targets 0-1 and 4. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.000000 fetch-budget caps, so this proposal stays unspent.

Temporal article on idempotency keys to prevent duplicate effects; conceptual support for targets 2-3 though not email-specific. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.000000 fetch-budget caps, so this proposal stays unspent.

GitLab Sidekiq idempotent worker docs; different framework and about declaring workers idempotent, not email provider dedupe. - free public original-page READ selection (not a cache hit); no purchase or creator reward.

Keryx release notes about CLI/MCP features; unrelated to email idempotency or crash recovery.

Keryx release notes on source catalog expansion; no bearing on the research targets.

Keryx release notes mention idempotent paid-job alerts but concern Keryx internals, not email-send idempotency.

Keryx buyer recovery doc is about resuming paid research jobs without re-paying, not about email provider acceptance vs persistence.
