Loss is the conceptual category marking the transition from possession or presence to absence or unavailability of something valued. Its parameters are the domain (material, relational, temporal, or informational), the mode (sudden or gradual, expected or unexpected), and the agent's relationship to the lost item (owner, witness, or affected party). It persists through language (grief vocabulary, accounting standards, insurance frameworks), social rituals (mourning, bankruptcy proceedings), and cultural narratives that give shape to absence. [formal: amissio | substrate: mind | horizon: a life | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
Loss is a human-made psychological construct — the irreversible removal of a valued bond, commitment, or shared identity. It is not merely absence but a recognized rupture that demands narrative integration. The mechanism of persistence is the repeated retelling and recontextualization of the loss that gradually integrates it into the survivor's ongoing identity.

A loss function IS a specific kind of metric: it quantifies the difference between predicted and actual values. It is a quantitative measure used to evaluate model performance — fitting the broader metric category.

TESTED DEPENDS_ON: Remove error — loss ceases to operate. A loss function's sole purpose is to quantify error; without the concept of error, loss has nothing to measure and its operation collapses. This is object-level, not meta-level.
