Definition. Attempt-local replay annotation [ftip-0057]
✍️source

    Selecting \(R\in \mathcal R_n\) under a current policy stamp \(\nu _n\) produces an attempt-local replay annotation

    \[a_n(R)=(\nu _n,\rho ,\kappa ,m,u),\]

    where \(\rho \) is the declared collection of behavior/current likelihood ratios, \(\kappa \) records clipping status, \(m\) is the record age, and \(u\) is its prior reuse count. Every component is computed for this attempt and may change at the next one.
