vldaft

Draft workflow for general vldaft R/C/Rust package development, backend parity, compiled interface changes, tests, package checks, and maintenance tasks. Use for ordinary implementation and verification work; use vldaft-model-development instead when the task starts from a new statistical model prompt.

Use when turning a statistical survival-model prompt into vldaft package code, especially new AFT distributions, cure models, censoring or truncation behavior, parameter/link definitions, likelihood/score implementations, C/Rust backend changes, gamlss2 family support, simulation checks, backend parity tests, and model-facing documentation.
