PR Review

• Read the diff and full renovate.json5 context
• Validated the new cron schedule
• Checked comment/config consistency

Verdict: LGTM ✅

The change is correct and idiomatic:

• schedule: ["* 0-3 1 * *"] is valid Renovate cron (minute hour(0-3) day-of-month(1) month day-of-week). Using * for the minute field is exactly what Renovate recommends — it doesn't schedule at minute precision, so the * just defines the 00:00–03:59 UTC window on the 1st of each month. No timezone is set, so this correctly defaults to UTC.
• The comment on line 11 was updated (weekly → monthly) to stay in sync with the change. 👍
• minimumReleaseAge: "14 days" is preserved as intended, and the "skip releases newer than 2 weeks" comment remains accurate.

One thing worth being aware of (not a blocker, and it matches the PR's stated intent): combining a monthly run with the 14-day release age means a fresh action release could take up to ~6 weeks to land in a PR. That's an acceptable trade-off for reducing PR noise, just flagging the effective latency.

No changes requested.

LGTM — monthly schedule cron is valid and matches stated intent (fires only on the 1st, wide enough window for Renovate's own polling cadence).
