Subject: [PATCH] fix: update drifted line citations in patterns.md
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two citations were out of bounds against kubernetes/kubernetes HEAD:

- delta_fifo.go:797-801 → 797-800 (DeletedFinalStateUnknown struct ends
  at line 800; file has 800 lines total, off-by-one)

- kube_features.go:2798-2811 → 2771-2784 (init() function moved up ~27
  lines; file now has 2784 lines, old citation was past EOF)

Audited all 30 citations (28 OK, 2 fixed, 0 flagged for review).

 When a watch disconnects and reconnects, some delete events may be missed. The DeltaFIFO synthesizes a `DeletedFinalStateUnknown` ("tombstone") containing the last known state of the object.
