- Line 164: Update the email span’s title binding in CodexAccountsMenu so that
when hideEmail is enabled and account.nickname is null, the tooltip uses the
masked shown value rather than the raw label/emailHint; preserve the existing
unmasked tooltip behavior otherwise.

Thermo-nuclear code quality review. Overall: well-shaped PR — the row extraction into CodexAccountRow is the right structure, hook reuse is correct, and tests assert the real contract. Two findings before this can merge.

1. Blocking: hideEmail invariant leaks at the tooltip boundary

apps/desktop-tauri/src/components/CodexAccountsMenu.tsx, in CodexAccountRow (~line 164):

const shown = hideEmail ? maskEmail(label) : label;
...
<span className="codex-menu-accounts__email" title={label}>

When hideEmail is on and the account has no nickname, label is account.emailHint — the raw address. The rendered text is masked, but hover reveals the full email. (CodeRabbit's walkthrough characterized masking as preserved; the tooltip defeats it.)

The fix is simpler than a ternary — shown already equals label when masking is off:

- <span className="codex-menu-accounts__email" title={label}>
+ <span className="codex-menu-accounts__email" title={shown}>

Please also add a test asserting the email span's title is masked when hideEmail is true (and equals the raw label when false) — the suite already covers both modes, so this is a small addition.

2. Minor: duplicated reset-label composition

const resetLabel = resetText
  ? resetTimeRelative
    ? resetText
    : `${t("MetricResetsIn")} ${resetText}`
  : null;

The same compose pattern exists in apps/desktop-tauri/src/surfaces/settings/providers/sections/UsageSection.tsx (~lines 104-106). Two copies is the start of a scattered pattern — suggest a small exported helper colocated with useFormattedResetTime (e.g. composeResetLabel(resetText, relative, t)) used by both call sites. Not blocking on its own, but cheap to do now while there are only two.

Verified non-findings

• formatWindowLabel is not a duplicate of localizeWindowLabel (different input contract: seconds vs raw string labels) — keeping it local is fine.
• Per-row 30s countdown intervals are acceptable at realistic account counts.
• Test quality is good: asserts window label, percent, localized reset, multi-account rendering.

Fix finding 1 (+ its test) and this approves cleanly.

Fix verified: finding 1 is resolved via title={shown} on the email span (commit 48860fa), which strictly simplifies the ternary variant while preserving the unmasked tooltip when hideEmail is off. Regression test added in CodexAccountsMenu.test.tsx asserting the tooltip equals the masked text with hideEmail on and the raw label with it off. Full frontend suite green: 291 tests passed (47 files) and pnpm run build succeeds.

Finding 2 (duplicated reset-label composition) remains accepted as non-blocking per the original review — it was explicitly not a merge condition.

Approving.
