qector-decoders-deep-dive

Per-decoder internals from the v1.0.0 reference manual. For each of the fifteen specialised backends, gives the algorithm, the theorem(s) it inherits, its claim boundary, and a one-line code snippet. Load when a question asks "how does X work", "which decoder is right for Y", or "what is the difference between A and B" at the algorithmic level (manual chapters 4-13).
