Wire the soul contract gate into ci.yaml as a hard block between the cc
build and the Publish-to-Artifact-Registry step. A non-zero gate fails the
build, so a stale (route-404ing) or memory-destroying (hard-deleting) soul
can never publish neuron-soul to foundation-prod or blue-green deploy to
GKE — the same class-fix now guarding the desktop builds, extended to prod.
Vendors scripts/verify-soul-contract.sh (copied from neuron-ui; the route
contract is baked in, so it's portable POSIX bash/curl with no neuron-ui
source dependency). It boots dist/neuron on a throwaway port with a
throwaway HOME/engram/cgi — never touching ~/.neuron or any live service —
and checks PRESENCE (every app route answered) + IMMUTABILITY (no engram
write route hard-deletes; deletes/forgets tombstone). Adds curl to the
build deps for the probe.
Dockerfile: downloads linux/amd64 soul binary from Artifact Registry
(foundation-dev/neuron-soul) into ubuntu:22.04 runtime image.
Pushes to neuron-api Docker repo as neuron-soul:<sha>.
scripts/blue-green-deploy.sh: swaps active slot on GKE — sets image,
scales new slot to 1, flips service selector, scales old slot to 0.
scripts/seed-engram-gke.sh: downloads latest GCS backup, extracts
snapshot.json, copies into neuron-engram-data PVC via a seed Job.
.gitea/workflows/deploy-gke.yaml: triggers on push to main, auto-detects
idle slot, builds Docker image from Artifact Registry binary, blue-green
deploys to neuron-prod on GKE neuron-platform cluster.
