The Tools section was a rank-ordered bar chart: one row per tool, the bar its call count, a red head where calls failed. It spent 400px of the overview answering "which tool was called most" — a question nobody arrives with — and never said when anything happened or how to reach the call that broke. It is now a ledger. The columns are the questions an engineer actually has (calls, failures, total time, slowest call), sorted by time spent, so the tool that burned the session is the first row. Beside them every call sits on the session's own clock, one mark per call at its start time and sized by its duration: a row says *when*, and clicking a mark opens that call's span in the inspection overlay. Expanding a tool discloses what the rail used to hide — the definition the model was given — together with each failed call, its error, where in the session it happened, and a way straight into the span. The cheap tail folds into one row, and a tool that failed keeps its own row however little time it cost, so a session reaching for forty tools still fits. `SessionToolUsage` carries the calls behind it to make that possible: each call's span id, start, duration, turn, and error. The prose extraction helpers move down into `session-summary` so both the findings list and a tool row can name a failure the same way.
…s room Time spent was the wrong first question for the ledger: how often the agent went back to a tool is what a reader scans the column for, and the cost of each stays one column over. Rows go to 24px, and the caption under the section goes — the marks explain themselves.
The folded tail saved a few rows and cost the reader a click to see what the session actually reached for. At 24px a row the whole inventory fits, and a ledger that hides its cheap end is not a ledger.
…headline Boundaries alternated 28px and 28-rule-28, header-to-content gaps ran 0, 14 and 12 across three sections, and a finding row carried twice the air of a tool row — the column read as dead space in some places and dense in others. Every boundary is now the same hairline with 24px either side, every section opens on the same 12px gap, and the finding rows tighten towards the density of the rest. "Completed, with N findings" goes with it. The findings list is directly below, counting itself in its own header; the headline said it twice and took the top of the page to do it. A failed or clean session still leads with its verdict — there the line is the only place the outcome is stated. The breakdown moves above the findings, so the page opens on the shape of the session before its faults.

`Record<string, ReactNode>` on the literal threw away the one thing the map knows — which icons exist — and `maple/no-record-string-any`'s open-dictionary rule fails the lint on it, which is what has had main red since the docs app landed. Inference plus `satisfies` keeps the check on the values, and the lookup narrows an arbitrary name to a key it holds rather than indexing an open dictionary.

Handle a zero offset in callWhen.
formatSessionDuration returns "—" for a value of 0 or less. A tool call that starts at the session start therefore renders turn 1, — in, 0.1s, both in the mark tooltip and in the failed-call row. The session start is the earliest span start, so a tool call can share it.
🩹 Proposed fix
- const at = `${formatSessionDuration(event.startMs - sessionStartMs)} in, ${formatToolDuration(event.durationMs)}`
+ const offsetMs = event.startMs - sessionStartMs
+ const since = offsetMs <= 0 ? "0s" : formatSessionDuration(offsetMs)
+ const at = `${since} in, ${formatToolDuration(event.durationMs)}`📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Clip the result-derived error detail.
The status-message path clips to 140 characters. The toolCallResult path returns firstProse(result) unclipped. A framework that records a long error value as the tool result gives an unbounded errorDetail, and FailedCallRow renders it as plain text in the ledger row. The previous helper in session-findings.ts applied clipDetail(prose) for the same reason.

Check own properties before indexing icons.
name in icons accepts inherited names such as "__proto__", "constructor", and "toString". These names pass isSidebarIconName, so sidebarIcon(name) can place a non-React object or function inside the SVG and fail during rendering. Use an own-property check and add regression tests for inherited property names.

The Overview's Tools section was a rank-ordered bar chart — one row per tool, the bar its call count, a red head where calls failed. It spent ~400px answering which tool was called most, a question nobody arrives with, and never said when anything happened or how to reach the call that broke.
Now
A ledger, ~150px for the same session:

SessionToolUsagenow carries the calls behind the totals: each call's span id, start, duration, turn index, and error label/detail, plustotalMs/slowestMs. Ordering moves from call count to time spent.
