The navigation-panes replay scenario clicks the trajectory toolbar export
button and asserts the real host-streamed download: filename, a single
session.jsonl entry, and byte-verbatim seed content. The toolbar golden
refreshes for the localized export button.
The 导出 button fetches GET /api/session.export and saves the ZIP (root
artifact plus subagent descendants). The plugin exposes exportLog through
the view's inject face, resolves the tab label through the locale service,
and disables the button while in flight; fixture mode answers 404 so the
error bar explains the gap.
Drop the details-panel Duration toggle: Duration rows always show
integer milliseconds, matching the cell time column. Timeline labels
(Total/TTFT/Decoding) and step-group descriptions previously fell back
to second labels at or above one second; they now also show exact
milliseconds via the shared formatDurationMillis formatter.
One two-turn seed (turn 1: bash + two parallel reads in a single assistant
message; turn 2: a markdown-heavy reply) rendered cold through the
seeded-history pattern — zero model calls — serving four surfaces:
- sidebar search: client-side title filter; asserted only after the durable
title lands with the attach baseline (a cold SessionSummary carries no
title — search matches the displayTitle the user sees). Negative query
empties the tree, positive narrows to the match + its force-expanded
group, clear restores.
- Trajectory tab: turn sections, the step group's tool mix ('bash read×2'),
and a view-area aria golden.
- Waterfall tab: span stats header + one lane per span. The P-I fold counts
a turn-0 prologue span (only assistant/steering nodes carry a turn
number) — pinned as-is; real spans are P-III per the view's ledger.
- details column: the bash toolview row routes click to openDetails;
open/closed is asserted on the frame's data-details-collapsed attribute
because close collapses the grid column to width 0 without unmounting
the subtree (hidden, not absent, is the contract).
Agent Note scenario list extended in both languages; pairing re-recorded.
