The actual problem is whether your retrieval layer can consistently surface the right code unit under ambiguity, noise, and naming collisions. This post builds a minimal retrieval system over Go functions and then lets it fail in predictable ways.</p> <p>The point is to have something concrete to measure against before adding complexity.</p>
