User Testing

Testing surface, required testing skills/tools, and resource cost classification.

Validation Surface

Surface	Description	Tool
Dashboard UI	Mission manager with assertions panel, loop states, validation controls	agent-browser
REST API	Assertion CRUD, validation trigger, loop state, runs, recovery	curl
CLI	Mission commands	Manual verification

Validation Concurrency

Machine specs: 28 CPU cores, 256 GB RAM

agent-browser (lightweight app):

• Dashboard is a lightweight web app (~200 MB with dev server)
• Each agent-browser instance: ~300 MB RAM
• Dev server: ~200 MB
• Usable headroom: 256 GB * 0.7 = ~179 GB (very generous)
• Max concurrent validators: 5 (standard max)

Resource Cost Notes

• Dashboard dev server (fn dashboard) needs to be running for browser tests
• API tests via curl are very lightweight — no concurrency limit needed
• Tests should use a fresh .fusion/fusion.db to avoid state pollution
