+# Pre-warm the pnpm content-addressed store with unleashlive/frontend +
+# unleashlive/api dependencies (speed win V1).
+#
+# The frontend's pnpm tree is ~3,500 packages; a COLD `pnpm install` inside a
+# fresh collab workspace takes ~10 min (network + download).  pnpm's store is
+# content-addressed and shared across installs, so if we populate it at BUILD
+# time, every runtime session install becomes a near-offline store-link op
+# ("Done in ~30 s") instead of a 10-min download.
+#
+# `pnpm fetch` is the right tool: it reads ONLY the lockfile (ignores
+# package.json), downloads every locked dependency into the store, and does
+# NOT link a node_modules tree — exactly a store warm.  We run it with
+# HOME=/home/opencode so pnpm's default store path resolves to
+# /home/opencode/.local/share/pnpm/store — the SAME path the runtime preview
+# install (uid 10001, HOME=/home/opencode) reads by default.  The final-stage
+# `chown -R 10001:10001 /home/opencode` hands the warmed store to the runtime
+# user.
+#
+# Auth: cloning these PRIVATE repos at build time needs a cross-repo read
+# token, provided as a BuildKit secret (id=github_token).  The token is
+# mounted at /run/secrets/github_token for this RUN only — it never lands in
+# a layer or the image.  When the secret is absent (local builds, or before
+# the deploy workflow is wired to pass it), the step logs and SKIPS cleanly —
+# the image still builds; runtime installs just pay the cold ~10 min until a
+# warmed image ships.  See DEPLOYMENT.md for wiring the secret in CI.
+#
+# Staleness is fine: a lockfile that drifts after build means pnpm fetches
+# only the DELTA at runtime (new/changed packages); the unchanged thousands
+# are store hits.  Even a week-stale warm removes the bulk of the cold cost.
