The rail now merges the turnOutline projection with loaded-window items
(view-layer only; loaded wins, outline fills mid-turn prompt previews),
renders unloaded turns as dimmer marks, and clicking one holds the
reader's place, pages history through the turn's seq, and lands on its
row after the commit — no height estimation. Settlement repages once
per head movement, then falls back to the nearest rendered turn.
The whole-line meta trigger read as plain text and hid what was clickable.
The Turn-usage trigger is now a data-icon pill (Usage {total} · Cache hit
{percent}%) seated right of the branch action with the action buttons'
hover chrome, so the one interactive element in the tail is visibly a
button; the timing facts (clock, run time, speed, TTFT) return to plain
non-clickable text behind a dot separator. The details dialog keeps the
Turn-usage title and full token buckets, gains a permanent cache-hit row,
and breathes with wider vertical padding. Narrow columns trim the pill
label to an ellipsis instead of widening the chat column. User rows and
turn tails share the recency gate: only the latest row of each kind keeps
its actions visible without hover.
