- 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
