Overview
A working notebook for turning a question into a thing that can be tested, felt, and improved.
Problem
A polished surface can still hide ambiguous state, unnecessary work, and unclear runtime ownership. The project makes those seams visible without replacing systems that already work.
Goals
- Model one surface with exhaustive loading, ready, empty, unavailable, unauthorized, and error states.
- Measure hydration, render count, App launch latency, and background work.
- Preserve existing code-split and playback ownership while hardening the remaining bridge.
Architecture
Database and API contracts → SDK validation → Artist Runtime projection → code-split App surface → canonical playback bridge.
Design
Failure and loading states should preserve the atmosphere of the Profile World without hiding what happened or what the person can do next.
Implementation
Start with a trace and profiler capture. Change the smallest ownership seam supported by evidence, add regression tests, and verify the real Profile World on mobile.
Lessons
- Profiling should precede refactoring.
- A finite state model can improve both the type system and the visible experience.
Future improvements
Generalize only after the chosen Profile World proves the boundary and the measurement remains useful.
