Each blueprint column is one transformer block. Hover or keyboard-focus a linked cell to read attention, feed-forward and residual structure as one aligned layer; linked cells open the corresponding walkthrough or inspector. DSA cells additionally preserve whether the layer runs a full indexer or reuses a shared IndexShare selection. QSA cells preserve their per-layer sparse retrieval identity, while PLE is marked on the decoder layer receiving N-gram features. MoE cells preserve any layer-level routing transition encoded by the checkpoint manifest. Structural encoding only — it does not imply benchmark quality, throughput or FLOPs.
