Structured-effect markers

Status-marked random-effect scale, structured covariance, and latent-correlation syntax; each reference page separates fitted routes from planned neighbours.

Deprecated marker internals

Older deprecated formula markers kept out of the main reader path.

Distributional outputs and adequacy

A first-class fitted distribution for every family, plus the adequacy diagnostics and centile/exceedance outputs built on it (#747, #748).

predict(<drmTMB_julia>): Predict from a legacy Julia-bridge drmTMB fit
summary(<drmTMB_julia>): Summarise a legacy Julia-bridge drmTMB fit

Visualization

Optional plotting helpers for post-fit tables. Exported plotting functions appear here.
