Offline Fetch, Vendor, and Cache

These commands support deterministic dependency preparation and cache lifecycle control.

Warm Cache Without Building

joy fetch

fetch resolves current manifest dependencies and pre-populates source caches.

Vendor Lockfile Dependencies

joy vendor
joy vendor --output third_party/vendor

vendor copies lockfile-resolved sources into a project-local directory, grouped by package slug and resolved commit.

Cache Garbage Collection

joy cache gc
joy cache gc --aggressive

• default gc: clears temporary cache paths
• --aggressive: also clears source/archive cache roots

Offline + Frozen Workflow

joy fetch
joy --frozen sync
joy --frozen build

For lock/source integrity checks:

joy verify
joy verify --strict --sbom sbom.json

Common Pattern for CI

joy --json doctor
joy fetch
joy --frozen sync
joy --frozen build
joy --json verify --strict --sbom sbom.json
