James Lind and PMC commentaries print the Canon’s observational rules as a case-writing method

The 2007 James Lind / PMC cluster emphasises identity of the drug, observation in a natural state, and related cautions — a completed modern commentary on a medieval method heading. In the causal graph this event strengthens Health-System Capacity, a driver that strengthens Hospital beds (per 1,000 people) — an improving welfare path.

The 2007 James Lind / PMC cluster emphasises identity of the drug, observation in a natural state, and related cautions — a completed modern commentary on a medieval method heading. Lost personal case-notes mentioned in the vita are not reconstructed here. The method as printed is observational, not a randomised trial.

Context

Humoral theory still frames the cases. Split depletion.

Avicenna is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

What changed

Fact → Driver → Indicator. Relationship strength orders the paths; it is not the observed indicator movement.
