Explanation

Background context and design decisions.

• matching-approach — Fellegi–Sunter framework, where we’re inspired by it, where we deviate
• alternative-solutions — why the repo carries multiple solution variants as siblings
• edge-cases — handled by v1, anticipated but deferred, roughly in priority order
• interview-repo-architecture — why the repo is heavily scaffolded before the real solution exists
• interview-session-strategy — how the repo aligns with the Mercury interview format
