A burden is the allocation of responsibility, obligation, or weight across agents. Parameters: (1) the burden-bearer who carries it, (2) the burdened object (proof, care, labor), (3) the weight or measure of obligation. Persistence: language (terms like 'burden of proof', 'burden of care'), law (statutory allocation of responsibility), and social convention (norms of duty). The map divides responsibility into distributable units that can be assigned, transferred, or shared between agents. [formal: onus | substrate: mind | horizon: hours | explicit: yes | epoch: 0.92]

The entry burden is human-made: it is a convention for distributing obligation across agents, not a natural force. The concept exists through language (the word 'burden' itself), law (burden-of-proof rules), and social practice (who carries what weight). The territory — actual effort or weight — is described but never enrolled.
