Learning: In test `testWindowJoinFailsWhenSlaveDoesNotSupportTimeFrames` in `core/src/test/java/io/questdb/test/griffin/WindowJoinTest.java`, the use of `AND` between timestamp equality conditions (e.g., `ts = 'X' AND ts = 'Y'`) is intentional to prevent intrinsic interval creation. This ensures the window join fails as expected when the slave doesn't support time frames, which is necessary after PR `#6673` added OR timestamp intrinsics recognition.

Learning: In test `testWindowJoinFailsWhenSlaveDoesNotSupportTimeFrames` in `core/src/test/java/io/questdb/test/griffin/WindowJoinTest.java`, the use of `AND` between timestamp equality conditions (e.g., `ts = 'X' AND ts = 'Y'`) is intentional to prevent intrinsic interval creation. This ensures the window join fails as expected when the slave doesn't support time frames, which is necessary after PR `#6673` added OR timestamp intrinsics recognition.

File: core/src/test/java/io/questdb/test/griffin/WindowJoinTest.java:2616-2618
Timestamp: 2026-01-19T21:43:19.228Z
Learning: In test `testWindowJoinFailsWhenSlaveDoesNotSupportTimeFrames` in `core/src/test/java/io/questdb/test/griffin/WindowJoinTest.java`, the use of `AND` between timestamp equality conditions (e.g., `ts = 'X' AND ts = 'Y'`) is intentional to prevent intrinsic interval creation. This ensures the window join fails as expected when the slave doesn't support time frames, which is necessary after PR `#6673` added OR timestamp intrinsics recognition.
