infra: drop predictions container (HOL-19) - #99
Merged
Conversation
Predictions was a Flask ML sidecar that scored sessions for upstream Highlight's SaaS dashboard. The .NET backend never called into it (zero references in src/dotnet/), so it's been spinning idle on port 5001 doing nothing useful for self-hosted deployments. Removed: - predictions service from compose.yml - predictions from start-infra.sh service list - packages/predictions/ directory (Flask app + Dockerfile + poetry.lock) - "predictions" mention in infra/docker/README.md Not touched (out of scope): - src/backend/alerts/predictions/, src/backend/jobs/metric-alerts/, src/backend/private-graph/graph/schema.resolvers.go — these live in the inactive Go backend. The Go code is dead in our deployments (.NET is the runtime path) but tearing it out cleanly would touch gqlgen schema regeneration. Separate cleanup ticket if Go ever fully goes away. Verified: docker compose ps shows one fewer service, smoke test (ingest pipeline + ClickHouse verification) still passes. Subtask of HOL-17. Closes HOL-19.
