Function mtp_refeed_accepted_enabled 

pub fn mtp_refeed_accepted_enabled() -> bool

2026-09-25: METRALE_MTP_REFEED_ACCEPTED=1: after a verify, ring the target’s hiddens for the accepted positions, so the catch-up feed can rewrite accepted drafter rows with the target’s hidden instead of the drafter’s own. It writes into the catch-up ring, which the model allocates only when mtp_catchup_enabled. Off otherwise, and off in mtp_multi_seq_mode. Measured 2026-07-21 on dgx2 at 2 drafts, about 10k verify steps per arm: p2_uncond 0.4182 off, 0.4452 on.
