Affected Assets, Files, and Routes:

CI root-cause update: the six Tooltip failures are reproducible as an nwsapi 2.2.25 regression, not a DatePicker change. PR #59150 independently failed the same two shards and the same six tests after that release. On this PR exact head, the affected files fail 6/55 with 2.2.25 and pass 55/55 (5 snapshots) with 2.2.24 or the focused guard restored. I reported the upstream regression at dperini/nwsapi#168 and submitted the fix at dperini/nwsapi#169. No DatePicker code change is needed for this failure; the check should be retried after the dependency is fixed or pinned. AI assistance disclosure: Codex helped trace the dependency and run the A/B verification; I reviewed and reproduced the results locally.

CI failed.

Confirmed. The failed shards are the six Tooltip tests described above. I checked the newly published nwsapi 2.2.26 before rerunning: a clean jsdom 26.1.0 install still throws the same TypeError for the compound selector and root :has(~ p), so rerunning now would remain deterministically red. The upstream fix is rebased onto current nwsapi master at signed/Verified head e33a8ae: dperini/nwsapi#169. I will rerun this PR after a fixed upstream release rather than add an unrelated DatePicker dependency pin. AI assistance disclosure: Codex helped run the clean-install 2.2.26 probe; I verified the result locally.

Thanks for flagging this. I rebased the PR onto current master and force-pushed signed commit 238ec0f309 (GitHub Verified), which started a fresh CI run.

The previous failures were six Tooltip tests failing inside nwsapi (Cannot read properties of null (reading 'children')), outside this DatePicker locale diff. After the rebase I locally verified:

• vitest components/date-picker/__tests__/other.test.tsx: 9/9 passed
• focused ESLint: passed
• focused Biome: passed
• git diff --check: passed

I will leave the new CI run to complete without further retriggers. AI assistance was used to inspect the failed-job logs and prepare the rebase/validation summary; the exact diff and commands were verified locally.
