Red on base: webviews/test/session-info-section-order-browser.test.tsx > "Session Info's six-dot handles > the default order draws the three blocks: 6px inside a block, none where it runs, 8px, a hairline, 8px between" fails on the first run and on the isolated retry (web / react-apps-check (4), push run 41330139801 at fb5f096). It expected about to be [0, 0] and got [0, 28].

Culprit: #28773 (Session Info's Usage) deliberately added a Usage section after Context in the top block (sectionOrder.ts GROUP_SECTIONS.about = ["environment", "context", "usage", "connectors"]) and updated session-info-section-order.test.tsx. It did not update the browser geometry test, which still measured from Context straight to Connectors. That measurement now spans Usage's 28px folded row.

Fix (test only, the design is the intended one): the test now measures Environment to Context, Context to Usage, and Usage to Connectors (each 0px, since the block runs with no gap). It also checks that neither Usage nor Connectors draws a hairline. The block gaps (16.5px) and the hairlines over Changes and Subagents are unchanged. No product change.

The ChiefsCard.tsx:58 CompileError line in the same log is not related. It is one of the 23 informational React Compiler bail-outs printed while the pages build, not a failure.

Summary by cubic

Fixes the Session Info six-dot geometry test, which failed after Usage was added to the top block (#28773). The test measured Context straight to Connectors, so it read Usage's 28px folded row as a gap.

Test only; no product change. The test now measures Environment to Context, Context to Usage, and Usage to Connectors (each 0px) and also checks that Usage and Connectors draw no hairline.

Review (subagent opus-5.5 medium): SHIP at 5f34c09

• Usage is in the top block by default (sectionOrder.ts GROUP_SECTIONS.about), and the gallery full variant the test mounts sets usageStats, so the usage slot renders between Context and Connectors (the 28px seen on base).
• Hairlines: SessionInfoGroup.tsx sets data-run-start only where the previous section is from a different block, so Usage and Connectors draw none; Changes and Subagents keep theirs.
• The test is not weakened: it gains one gap check and two hairline checks, and drops nothing.
• The ChiefsCard.tsx:58 CompileError line is a React Compiler bail-out that bundle.mjs prints and never fails on. It is unrelated.

Follow-ups: none.

Review (delta, lane owner opus-5.5 medium): SHIP at d6a5cf6. The delta from the reviewed 5f34c09 only hoists the section list into const ruled so the line fits the format width (fast gates failed vp fmt --check on this file); same values, same assertions.
