Parallel Go reimplementation of the dereth-tracker read side, deployed loopback-only (:8770) and reading the dereth TimescaleDB read-only. The live Python stack is untouched (added via a compose override, not by editing the tracked docker-compose.yml). - Phase 0 scaffold: stdlib net/http server (Go 1.22+ method+path routing), /health + /api-version, multi-stage distroless Docker build, and go-services/docker-compose.go.yml override (loopback :8770). - Phase 1: pgx v5 pool forced into read-only transactions, a 5s /live + /trails cache loop using the exact main.py:837 SQL, and Python-isoformat timestamps so output matches FastAPI's jsonable_encoder. - compare/compare_live.py: parity harness vs the live Python service. Uses the server-stamped received_at to prove same-row full-field equality and to make the online-set diff boundary-aware. Verified on live traffic (73 players): identical online set + 23-key schema, identity/type parity for all, every same-row pair matches on every field, and diff-row pairs differ only by the ~6s two-cache refresh skew.
