Versioning & pinning
Pinned, reproducible universes for CI. A snapshot regenerates byte-identically on every request, so pinned tests never drift.
Live vs. snapshot
- Live — the gh. / gl. hosts serve a continuously-fresh universe (newest activity within hours). Great for exploration.
- Snapshot — a pinned *.snap. host serves a reproducible universe that regenerates byte-identically on every request. Great for CI.
Pinning is a hostname swap
Point your client's base URL at a snapshot host instead of the live host — nothing else changes.
