 - P23: a branch version past its total logs and shows a dash, its arrows off; a parameter outside its range logs and pegs; a passage's matches outside it log and stay out. Kept: one-value contracts (progress, scores, shapes, peaks, levels, limits, prices, capacity, format, hour), the composer's trigger rows and stream reveal by construction; `places` skips zero, so `decimals` meets no zero step. Review: 2 rounds.
 - P24: a checkpoint or browser frame past its list logs and marks none; progress past its total and memory past its limit log and fill their bars, the text keeping the real counts; three `should_panic` tests became render tests. Kept: the artifact's preview-or-source builder check, one-value contracts (cost, cpu, pointer, totals and limits above zero), registry lookups over a constant table. Review: 1 round.
 - P25: a verdict, ratio, style, shot, voice, variation or prompt version gone from its list logs and marks none (no picture, no Vary or Upscale, no diff); embedding points in a gone group stay out; an epoch and GPU memory past their whole log and peg. A seed field holds a seed: each field handed in is fitted, and text that is no seed clears; in `TextInput`, a fit starts a fresh undo history, undo keeps and `set_text` fits against the committed text, never an input method's unfinished one (`committed`), and a lifted mask stroke stays on its picture. Kept: one-value contracts, unique group names, one snapshot's loss lists, two to four sides, the legend's lookup. Review: 5 rounds, the cap; round 5's finding (`set_text` over a composition) is fixed and tested, and P26's review checks it.
+- P26: a live position past its media logs and sits at the end (`media::played`); loaded time, a trim and chapters past the length peg or stay out; a gone device or track, or a refused trim, leaves none and clears the last; a dropped root path shows whole; subtitle times no clock holds read as none; a rail layout left no width gives no share (`scrubber::along`), so hover, press and drag skip it; waveform buckets count in `u64`, which a 32-bit web `usize` outgrows. Kept: non-zero lengths, one-value contracts, one list's uniqueness and order, lookups by construction. Review: 4 rounds; it also passed P25's last fix.
