+# 012 — SLURP Idempotency, Backpressure, and DLQ
+
+- Area: `pkg/integration/slurp_client.go`, `pkg/integration/slurp_events.go`, config
+- Priority: High
+
+## Background
+SLURP event delivery has retries and batching but lacks idempotency keys, circuit-breaking/backpressure, and a dead-letter queue (DLQ). Under failure/load this can produce duplicates or data loss.
+
+## Scope / Deliverables
+- Idempotency:
+  - Generate a stable idempotency key per event (e.g., hash of {discussion_id, event_type, timestamp bucket}).
+  - Send via header `Idempotency-Key` and include in body for server-side dedupe (if supported).
+- Backpressure & Circuit-breaker:
+  - Add exponential backoff with jitter and max retry window.
+  - Implement a circuit-breaker that opens on consecutive failures, stops sending for a cooldown, then half-open probes.
+- DLQ & Replay:
+  - Persist failed events (JSONL or lightweight queue) with reason and next-attempt time.
+  - Add a background replay worker with rate limiting and visibility into backlog.
+- Metrics & Logging:
+  - Prometheus counters/gauges: events_generated, sent, failed, deduped, dlq_depth, circuit_state; latency histograms.
+  - Structured logs for failures with keys.
+
+## Acceptance Criteria / Tests
+- Under induced 5xx or timeouts, client opens breaker, stops flooding, writes to DLQ, then recovers and drains when service returns.
+- Idempotent resubmissions do not create duplicates (server returns success with same id), counters reflect dedupe.
+- Unit tests for backoff, breaker state transitions, DLQ persistence, and replay.
+
+## Notes
+- Keep DLQ pluggable (file-based default); allow disabling via config.
