# @v2/hotfix-delivery-service

Hotfix delivery service for `TODOS.phase-72.72.12.2.8`.

The package publishes signed manifests for small data-only patches that modify
game balance, fix exploits, or correct data errors without requiring platform
certification.

Primary exports:

- `buildV2HotfixDeliverySurface`
- `planV2HotfixDelivery`

Service endpoints:

- `GET /v2/live-ops/hotfixes/{environment}/manifest`
- `GET /v2/live-ops/hotfixes/{environment}/delta/{clientBuildId}`
- `POST /v2/live-ops/hotfixes/{environment}/{hotfixId}/acknowledge`

The service validates hotfix kinds, environments, rollout percentages, signed
manifest IDs, data-only flags, no platform certification flags, no client patch
flags, and per-hotfix operations before a package can be delivered.
