David vs Goliath

Simple mutex-based lock with exponential backoff

Complex distributed consensus algorithm (incomplete)

Found the root cause: unclosed channel in goroutine

Attempted complex memory profiling approaches

Event sourcing pattern with local state cache

Stateless reconnection (missed state recovery requirement)

Used proven token bucket algorithm from textbook

Various custom implementations with bugs

PEG parser with custom combinators

Attempted regex-based solution (hit catastrophic backtracking)
