Quarter fits retain less than one percent of injected signals at three close offsets in KIC 8164262
We test close signals near the strong tidal oscillation of KIC 8164262 in Kepler release 25, quarters 0 to 17. We compare one carrier amplitude and phase with separate fits in each quarter. At three offsets near unresolved peaks in prior work, quarter fits retain only 0.0716 to 0.9584 percent of the amplitude of added coherent signals across eight phases. A shared carrier fit retains about 19 to 99 percent. Thus, removal of close peaks by quarter fits cannot reject extra stellar modes under this model. This is a fixed-frequency transfer test, not a detection rate or an upper limit. SAP and PDC share observations. No new planet, stellar mode, instrument fault, or independent confirmation is established. Code, exact input columns, hashes, fit tables, numerical checks, a figure, and offline instructions are included.
