PR-MODEL-ROW-AND-OAUTH-EMAIL-FIX-0: 2 of 6 bug bundle (height-clip + email-leak)

[jackwener]

Why

WAWQAQ msg c71b4dcb and 77221a77 flagged 6 issues across 2 screenshots in Settings → 模型 / 默认模型. After @maka-审美专家's analysis we split them into root-cause buckets:

Bug	Root cause	Status
1: model-row second line clipped	Button size="md" ships fixed h-9; rows now have 2 lines	✅ this PR
2: middle row appears with different background	same height-clip; the apparent "white middle row" is just :hover state on the taller row	✅ this PR (transitively)
3: long title truncation doesn't match raw-id truncation	already has overflow:hidden + text-overflow:ellipsis; visible artifact was bug 1 height-clip misread	✅ this PR (transitively)
4: refresh button uses mint primary color (attributed to PR #329 L3)	PR #329 L3 was NOT merged; the mint button is the existing --primary token unchanged	⚠ misdiagnosed
5: default-model dropdown lacks model-within-connection selection	needs new setDefault({slug, model}) IPC + GeneralDefaultsCard rewire onto grouped Select	🔜 separate PR
6: Codex OAuth dropdown leaks user email	connection.name built as Codex OAuth · ${state.email} at the source	✅ this PR

What's fixed in this PR

Bug 1: model row second line clipped (1 of 4 model-list bugs)

.modelTableRow is a Button recipe whose default size="md" ships h-9 (36px fixed). Each row now has TWO text lines (display name + raw id when showRawId), so the second line's lower descender got clipped ("gpt-5.4" → "ant 5.4" in the screenshot). Recipe override:

.modelTableRow {
  height: auto;
  min-height: 44px;
  padding: 8px 10px;  /* was 4px 8px */
}

This also resolves bug 2 (the apparent "middle row has a different background" is just the focused/hovered state on the taller row, reading as expected behavior with the height fixed) and bug 3 (.modelTableRowId already had truncation; the visible mismatch was the same height clip misread).

Bug 6: OAuth display name leaks user email

apps/desktop/src/main/main.ts:347 and :402 were building the connection display name as Claude OAuth · ${state.profile.email} (and the symmetric Codex path). That value is persisted as connection.name and surfaces in every model picker, settings dropdown, account list, and capability audit — anywhere the connection is identified by name. The email belongs on the Account · 模型 page, not in the model identity. Both paths now use brand-only labels.

What's deferred

Bug 5 — separate PR

GeneralDefaultsCard currently shows ONLY connection options (e.g., "Claude OAuth", "Codex OAuth"); WAWQAQ wants the dropdown to also let the user pick a specific model within that connection. The fix requires:

• A new IPC contract setDefault({slug, model}) (vs current setDefault(slug))
• Rewiring GeneralDefaultsCard onto the grouped Select pattern that ChatModelSwitcher already uses (packages/ui/src/chat-model-switcher.tsx)
• Migrating existing stored defaults

This is a backend-touching change with its own contract scope. Filing as a separate PR per scope discipline.

Bug 4 — misdiagnosed

The aesthetics expert's bug 4 claim ("mint button is PR #329 L3's fault") doesn't hold: PR #329 L3 commit 023b90b2 was NEVER merged (only the L1 vibrancy unblock from 7d008d51 shipped). The sage-green refresh button is the existing Button variant="default" rendering --primary, unchanged for weeks. No fix needed.

Tests

tsc --noEmit clean against my edits. Two pre-existing TS errors (displayName in model-catalog-choices.test.ts and recordActiveFullCompactBlock in main.ts:888) also fail on main without my changes; unrelated.

Pure-CSS height change + main-process string-literal change; no JSX/IPC surface changes.
