# Flow Scale Readiness Closure

Decision: 90% ready, live-volume and provider-credential proof pending.

## Proof lanes

### Load and soak
- Status: ready-with-production-volume-proof-pending
- [x] load budget
- [x] soak window
- [x] p95 thresholds
- [x] tenant pressure

### Queue and webhook pressure
- Status: green
- [x] webhook storm
- [x] queue backlog
- [x] retry drain
- [x] dead-letter visibility

### Provider outage recovery
- Status: green
- [x] degraded provider
- [x] fallback route
- [x] recovery ETA
- [x] incident owner

### Incident and SLO communication
- Status: green
- [x] SLO health
- [x] incident timeline
- [x] customer update
- [x] postmortem path

## Acceptance
- [ ] Ops can explain system health without reading raw logs.
- [ ] Queue pressure and webhook storm states show owner, retry path and ETA.
- [ ] Provider outage behavior is customer-safe and does not leak internals.
- [ ] Scale tests are archived with thresholds and result status.
- [ ] Incident communication has owner, timeline and postmortem path.
- [ ] Production-volume proof is not faked before real traffic exists.

## Remaining proof
- [ ] Run production-like soak test with target tenant mix.
- [ ] Archive webhook storm proof against real connector credentials.
- [ ] Capture one provider outage simulation with customer-facing recovery message.
- [ ] Validate SLO thresholds against live traffic after first customer cohort.
