The Brief
What you'll do, and what you'll demonstrate.
Produce a TLA+ formal specification of the rate-limit service that model-checks 3 critical properties and surfaces hidden race conditions before the rewrite ships.
Earning criteria — what you'll demonstrate
- Express a distributed lease protocol in TLA+ (or PlusCal)
- Distinguish safety vs liveness invariants and model-check each
- Use TLC to surface race conditions a code review would miss
- Translate a formal spec into engineering guidance for implementation
