Task truth today, broader memory over time

Ledger is the task-memory foundation of YYLO's System of Work. Today it owns task state, dependencies, responses, history, archives, and commit links. Decisions, agent attempts, deployment, and production outcomes are connected through other lifecycle evidence and the emerging Engineering Change direction; they are not all fields in the current task record.

Preserve existing state

YYLO Ledger migrations preserve existing state and protocol versions. Product identity changes do not reset persisted task truth.
