A team of 8 engineers adopted Astro 4 with tRPC expecting seamless, type-safe APIs across web, mobile, and third-party consumers. Within six months, serialization overhead added 340ms to p99 latency , the mobile bundle swelled by 1.8 MB, and two engineers spent 380 hours debugging type mismatches that tRPC's "zero-overhead" promise never mentioned. This is the story of what nobody tells you about running tRPC at the cross-platform boundary — with real code, real numbers, and real fixes.
