- Remove //go:build red_gate tag from internal/web/handlers_test.go and internal/db/pool_test.go now that consumer symbols are about to exist - go mod tidy after real importers land (deferred from Plan 01-01 per Codex concern #1) — chi/v5, templ, pgx/v5, google/uuid now in require list - internal/db/pool.go: NewPool(ctx, dsn) builds a pgxpool.Pool with MaxConns=10, MinConns=1; no eager Ping (RESEARCH Pitfall 2) - internal/web/slog.go: NewSlogHandler returns JSON when env='production', text otherwise; pure helper, no slog.SetDefault side effect - internal/web/middleware.go: RequestIDMiddleware (UUIDv4 → ctx + X-Request-ID header), LoggerFromContext helper, SlogLoggerMiddleware factory using chi WrapResponseWriter; field allowlist per V7/T-01-09
