Problem

A subagent row in the web chat timeline shows a one-line preview of the subagent's result. When that result contains a Markdown image or a link whose URL has parentheses, the preview keeps stray punctuation:

• ![screenshot](shot.png) Verified shows as !screenshot Verified
• [docs](https://en.wikipedia.org/wiki/T3_(protocol)) shows as docs)
• [report](outputs/report%20(final).md) shows as report.md)

Mobile had the same bug and fixed it in #23538. The web copy of that helper (plainDetail in V2LifecycleRow.tsx) was not updated, so web still shows the broken preview.

Change

Move plainDetail unchanged into the existing V2LifecycleRow.logic.ts so it can be tested, then use the link regex from #23538 (identical to mobile's subagentCardDetail). It drops the optional leading ! and accepts escaped or balanced parentheses inside the URL. The test reuses mobile's four cases.

Scope and approval

Very small, focused fix for an obvious bug, so no prior issue: web keeps a parity gap that #23538 already fixed on mobile, and the fix is the same one-line regex. Similar to the #25468 → #29601 follow-up. Overlap search: the local PR index and gh search prs ("subagent preview link", "V2LifecycleRow plainDetail") found no open PR touching this helper. #17420 (open) edits subagent rows but not this function.

Verification

• Red on main (with only the move applied): vp test run src/components/chat/V2LifecycleRow.logic.test.ts: 3 of 4 new cases fail, e.g. AssertionError: expected 'docs)' to be 'docs' and expected 'report.md)' to be 'report'.
• Green: 7/7 pass in that file.
• vp run check:changed: pass (format, lint, knip, typecheck, test, react compiler).
• Not checked: a real-client capture. The change is text the preview derives, covered by the unit test. Hover tooltips still use the shared subagentDetailPreview, which keeps raw Markdown on both clients. That behavior is unchanged here.

- Line 25: Update the Markdown link-removal logic in the plainDetail
transformation so link destinations with nested parentheses, such as
`[docs](foo(and(bar)))`, reduce to the link text `docs`. Track balanced
destination nesting or use an existing parser, and add the nested-parentheses
case to the existing table.

Walkthrough

The lifecycle row now imports plainDetail from its logic module. The exported helper removes Markdown markup, list markers, and extra whitespace. Tests cover image and link text, including link destinations with parentheses and encoded spaces.

Changes: Lifecycle detail formatting

Extract and test detail formatting apps/web/src/components/chat/V2LifecycleRow.logic.ts, apps/web/src/components/chat/V2LifecycleRow.tsx, apps/web/src/components/chat/V2LifecycleRow.logic.test.ts	The logic module now exports plainDetail, and the lifecycle row imports it instead of defining it locally. Tests cover image and link markup while preserving readable text.

A narrow preview-formatting issue remains for links with nested parentheses; it does not block normal lifecycle operation.

Verified in a real dev environment

Verified as-is at 292b9bbfd451d15f715a087f63bb930dfde941e7 on Linux with repository Playwright and /usr/bin/google-chrome.

• Installed and ran github/main (5b9731cedc) in a separate worktree first. Created a local Git project through the app and selected Codex gpt-6.1-sol. A real delegated child returned Markdown containing an image, a parenthesized URL, an encoded-space filename with parentheses, and an escaped parenthesis. Main displayed !screenshot Verified docs) report.md) escaped plain code..
• Stopped main before starting the exact PR head. The same persisted conversation displayed screenshot Verified docs report escaped plain code.. A fresh Codex parent/child turn on the PR produced the same corrected preview.
• Neighboring behavior passed: a fresh child containing list markers, inline code, a normal link, and a newline displayed plain code normal second line. Clicking the child row opened its thread, browser Back returned to the parent, and the child's rendered links retained their complete destinations. Collapse/expand continued to show the corrected preview. The hover preview retains raw Markdown, as described in this PR.
• Blacksmith vp run check:changed 065a43355c76ebf4abc6471ada818c25668b01b9 passed format, lint, both knip passes, affected typechecks, all 7 lifecycle logic tests, and scoped React compiler checks. The worker needed a depth-2 fetch of this head for comparison history. No source changes or pushes were needed.

Short command and runtime transcript

Not verified

Native desktop, iOS/Android, other providers, and remote/tunnel connections were not exercised on this Linux web-client pass. Actual image retrieval and external destination availability were not tested; the change formats the result text. Deeper nested-parenthesis parsing remains the explicitly deferred limitation discussed above.
