 The footer switches control the totals row, event rows, and the context basis, and the footer stays pinned above the composer while the table scrolls. `Show context delta` is off by default; when on, every turn and step shows its prompt-size change against the previous measured value in that scope, with negative deltas (for example after compaction) in the error colour. An expanded step row fills the Trigger column with its start timestamp (`MM-DD HH:MM:SS.mmm`; the tooltip carries the full `YYYY-MM-DD HH:MM:SS.mmm`) and any gap of at least one second since the previous step; sub-second scheduler noise is hidden. A step carrying a model answer is expandable: clicking its row opens a detail row that renders the answer as Markdown through the shared Chat primitive, capped at 16,000 characters with a truncation notice.

 - **Not mounted by the default product.** The Web bundle refuses experimental packages by rule; the optional Developer tools bundle (`@deepseek-ai/dsh-experimental-inspector-profile`) mounts this view, or a profile can add the row explicitly.
 - **Trimmed windows lose start times.** When the loaded window begins mid-step, first-token, model time, and total time cannot be derived; the row says `start unknown` instead of estimating.
 - **Code-Mode dispatches merge by root-call context.** Inner calls carry no turn or step, so each root call opens its own context keyed by the root call id, and the builder merges its dispatches into the step that owns the runner. A window that lost the dispatch start still merges the calls but cannot show their measured duration.
-- **Five shipped locales fall back to English.** German, Spanish, French, Portuguese, and Russian dictionaries and metadata ship now so shipped-language gates pass, but their strings are currently English copies.
 - **Older-page retries are explicit.** A page request reports `grew`, `exhausted`, or `retry`; when Chat or Trajectory owns the Session's in-flight page, the Statistics trigger stays visible instead of marking history exhausted or throwing.
 - **Known limitation: no whole-session wall projection.** The totals row substitutes model time + tool time because the host projections expose no whole-session wall clock. The tool segment sums paired call durations, so parallel calls can make that split look longer than a non-overlapping wall interval. This is recorded here; the view does not change host logic to fill the gap.
 - **Browser evidence is a test-only overlay.** Package tests cover folding, aggregation, formatting, and the jsdom table; `apps/web/tests/client-ui-perf-panel.e2e.ts` mounts the plugin through a test-only overlay over the shipped Web surface and compares a committed ARIA golden. No recorded-session scenario exists.

 - **已知限制：没有整段墙钟 projection。** 合计行的总用时用模型用时 + 工具用时替代，因为宿主 projection 没有整段墙钟；工具段是逐调用求和，并行调用会让这段显得比非重叠墙钟更长。这里作为已知限制记录，插件不为此改动宿主逻辑。
