Dev — Build & local smoke test / build-smoke (pull_request) Failing after 3m54s
k3s needs CAP_SYS_ADMIN to create network namespaces and mount cgroups. USER landing was preventing this. Cloud Run gen2 is the security boundary. 60% CPU was too conservative for soul-demo — it is I/O-bound (LLM API calls), not CPU-bound. 80% gives correct headroom before scaling kicks in.

# Dockerfile.stage — Stage build: landing server + soul-demo in one image.
|
|
#
|
|
# Both processes run in the same container:
|
|
# - neuron-web on port 8080 (landing page server)
|
|
# - soul-demo on port 7772 (demo chat, localhost only)
|
|
#
|
|
# neuron-web is built by `elb build` in CI (not here). elb compiles each
|
|
# .el source independently and links the result — no combined mega-file,
|
|
# no exponential memory growth. The binary lands at dist/neuron-landing
|
|
# (linux/amd64) and is COPY'd directly into the runtime image.
|
|
#
|
|
# soul-demo.c is pre-committed (small, no OOM risk) and compiled here.
|
|
|
|
# ── Stage 1: compile soul-demo ────────────────────────────────────────────────
