Overview

Resolves authentication strategy names to strategy instances

Handles strategy lookup with caching and pattern matching:

  • Exact match: ‘authenticated’ → looks up auth_config[‘authenticated’]

  • Prefix match: ‘custom:value’ → looks up ‘custom’ strategy

Results are cached to avoid repeated lookups for the same requirement.

Examples:

resolver = StrategyResolver.new(auth_config)
strategy, name = resolver.resolve('session')
strategy, name = resolver.resolve('oauth:google')  # prefix match
