YAO Human Meridian Atlas - sources and limitations
================================================

Scope: 361 classical point identities, 12 primary meridians plus Ren and Du.
The 309 paired identities and 52 midline identities produce 670 sites.
This is a model-based educational reconstruction. Clinical review: pending.
It does not show internal meridian branches, needling depths or trajectories,
extra acupoints outside the classical 361, or a female reference anatomy.

Only standard factual names and identifiers were extracted. No WHO or other
textbook location paragraphs, illustrations, indications or methods copied.
YAO's 54 existing point descriptions remain unchanged and take precedence.

Nomenclature aliases: TE=SJ, CV=Ren/RN, GV=Du. Display uses TE/CV/GV.

KNOWN LIMITS
The upstream anchor set mixes measured anatomy, proportional cun, stature
fractions and approximate facial offsets. Numerical completeness does not
establish clinical accuracy. A single adult male model cannot represent all
individuals, body shapes, tissue changes or the different postures used to
locate points. Hairline and soft-tissue landmarks are especially variable.
The skin has limited auricle, oral and finger detail. A ray that starts just
outside the skin is checked inward before nearest-surface projection.
Each placement records its method. Nearest-surface results are explicitly
flagged in the detail panel. The catalog diagnostics enumerate them.
Lines depict reconstructed surface courses. Internal branches and crossing
relationships are not inferred from a simple line between numbered points.
The fallback mannequin is schematic and its displayed points retain the
anatomical model coordinates; the fallback is visibly identified as such.
