// git-workflow.mjs — agent → test → prod memory pipeline (branch/diff/promote).

// Demonstrates the Git-style workflow for vector memory: branch a feature off
// production, ingest into it, review the change with diff(), then promote() the
// vetted delta back into production. Production is untouched until you promote.
