API Reference — public surface, symbol-anchored

§ docs/references/api.md 80 words τ ~1 min read
Moved. The per-module API reference now lives in seven symbol-anchored
files — R1 config · R2 transformer
· R3 mask & attention ·
R4 diffusion & self-conditioning ·
R5 loss & training · R6
sampler & eval · R7 data & utils.

The coverage gate (scripts/check_docs.py --coverage) requires every public

symbol to stay cited across the doc corpus; R1–R7 are the per-module homes.

Concept depth lives in the concepts tree.
