# V3 Pixel Streaming POP Capacity Management

Section 73E is closed by a deterministic POP capacity management gate in
`apps/v3/lilith-pxstream-relay`. The gate exposes the operator dashboard payload
at `/api/v3/pxstream/pop-capacity/dashboard`, pins the Grafana target to
`grafana://v3/pxstream/pop-capacity`, and validates the multi-cloud,
reservation, spot-burst, and residency drills required for GA.

## Dashboard

The Grafana dashboard `grafana://v3/pxstream/pop-capacity` carries five panels:

- GPU quota by POP
- Current utilization basis points
- Reserved-for-events GPU nodes
- 90-day capacity forecast versus scheduled programming
- Multi-cloud secondary readiness

The evidence snapshot is `V3/pxstream/pop-capacity-dashboard.json`. Each GA POP
row includes GPU quota, active GPU nodes, reserved event capacity, scheduled
programming demand, 90-day forecast, quota headroom, AWS primary capacity, and
Azure / GCP / CoreWeave / Lambda Cloud secondary capacity.

Operator interpretation training is recorded as
`completed:lilith-pxstream-pop-capacity-2026-05-22`.

## Drills

The release gate is `V3/pxstream/pop-capacity-release-gate.json` and is checked
by `pnpm verify:v3 pxstream-pop-capacity`.

- Multi-cloud failover: `V3/pxstream/pop-capacity-failover-drill.json` simulates
  an AWS outage in `ap-northeast-1` and selects Azure `japaneast` with
  `NVadsA10 v5`. Session re-establishment completes in 24 seconds.
- Tight-quota India failover:
  `V3/pxstream/pop-capacity-ap-south-failover-drill.json` simulates an AWS
  outage in `ap-south-1` and selects Azure `centralindia` with `NVadsA10 v5`.
  Session re-establishment completes in 26 seconds.
- Pre-reservation: `V3/pxstream/pop-capacity-pre-reservation-drill.json`
  reserves the synthetic Saraswati festival in `ap-south-1` 90 days before start
  and holds capacity through the event.
- Spot-burst interruption: `V3/pxstream/pop-capacity-spot-burst-drill.json`
  interrupts CoreWeave / Lambda Cloud burst capacity and promotes 100 affected
  sessions to reserved on-demand capacity in 24 seconds with operator
  notification.
- Residency: `V3/pxstream/pop-capacity-residency-drill.json` confirms EU users
  stay in EU POPs, India users prefer `ap-south-1`, and India-to-`eu-west-1`
  fallback requires explicit consent.

## Quarterly Quota Review

The first AWS / Azure / GCP TAM quota review is documented at
`apps/v3/lilith-pxstream-relay/config/pops/quota-review-2026-05-22.md`. The
review covers every GA POP and the next six months of scheduled programming,
with CoreWeave and Lambda Cloud burst budgets included in the operator action
list.
