Platform update — May rollups

Three things shipped this month that are worth knowing about even if you don't work on the platform team.

Build pipeline cut to under 6 minutes

The platform team rewrote the test sharding for zephyrcart/platform. Cold builds now finish in 5m40s p50 instead of 12m. The savings come from running integration tests in parallel against per-shard ephemeral PostgreSQL containers. Detail: PR #14228.

Frankfurt region capacity doubled

Customer growth in DACH pushed Frankfurt utilisation above 60 % at peak. We doubled the API tier and the PostgreSQL read replicas. No customer-visible change; latency p99 dropped from 92 ms to 71 ms.

Lucene index for product search rebuilt

The new schema indexes metadata.* fields if their key starts with searchable_. Catalog teams, you may now ship the metadata-as-facets work that was blocked on this.
