feat(dealix): k6 smoke test, SLO definition, fault-injection tests, env update 
Close 3 more launch gates:
- T5: k6 smoke test script (scripts/k6_smoke_test.js) with p95<500ms
  and <1% error rate thresholds, tests health/pricing/DLQ/approvals
- O5: SLO.md with latency targets per endpoint category, recovery
  objectives (RPO 24h, RTO 15min), and escalation matrix
- DLQ fault-injection tests (6/6 passing): webhook crash → DLQ,
  retry-then-succeed, exhausted retries → dead, circuit breaker
  open/recover, multi-queue isolation

Also:
- .env.example updated with POSTHOG_*, MOYASAR_SECRET_KEY,
  MOYASAR_WEBHOOK_SECRET, DLQ_*, CALENDLY_* settings
- LAUNCH_GATES.md updated: 13/33 gates closed, 5 blocked on
  founder API keys (PostHog/Moyasar/HubSpot/Calendly/UptimeRobot)

Version: 1.0.0
Effective: 2026-04-23
Review: Monthly, or after any incident

API Availability

SLI Target Measurement Alert Threshold
Uptime (monthly) 99.5% UptimeRobot on /api/v1/health < 99% triggers incident
Health endpoint response < 200ms p95 k6 smoke test > 500ms p95

API Latency

Endpoint Category p50 Target p95 Target p99 Target
Health / public reads < 50ms < 200ms < 500ms
Pricing / plans < 100ms < 300ms < 1000ms
Lead CRUD < 200ms < 500ms < 2000ms
AI agent calls < 2000ms < 5000ms < 10000ms
Webhook processing < 500ms < 2000ms < 5000ms

Error Rate

Metric Target Alert
HTTP 5xx rate < 0.5% of requests > 1% for 5 min
Webhook failure rate < 2% > 5% for 15 min
DLQ depth < 10 entries > 50 triggers alert

Recovery

Metric Target
RPO (Recovery Point Objective) 24 hours (daily DB backup)
RTO (Recovery Time Objective) 15 minutes (tested via drill)
Rollback time < 5 minutes (git checkout + restart)
MTTR (Mean Time To Recovery) < 30 minutes

Revenue Funnel

Step Freshness Target
Lead capture → PostHog event < 5 seconds
Payment webhook → PostHog event < 10 seconds
DLQ entry → first retry < 60 seconds
Approval request → notification < 5 minutes

How to Verify

# Health latency
curl -w "%{time_total}s\n" -o /dev/null -s https://api.dealix.me/api/v1/health

# k6 smoke test
k6 run --env API_BASE=https://api.dealix.me scripts/k6_smoke_test.js

# DLQ depth
curl -H "Authorization: Bearer $TOKEN" https://api.dealix.me/api/v1/admin/dlq/queues

# Circuit breaker states
curl -H "Authorization: Bearer $TOKEN" https://api.dealix.me/api/v1/admin/circuit-breakers

Escalation

Severity Condition Response
P1 - Critical Service down > 5 min Immediate (see RUNBOOK Scenario 1)
P2 - Major Error rate > 5% for 15 min Within 1 hour
P3 - Minor Latency > SLO for 30 min Within 4 hours
P4 - Low DLQ depth > 20 Next business day
