Third time stamp, version 2: result of the pre-registered pixel-location test for TIC 207109417 (sector 97), run once on 9 November 2026: class TARGET, unconfirmed

Abstract: Third time stamp of the author's TESS project. It records the SHA-256 digest of one local hash list that was written on 8 November 2026 (22:29 CET), before the pixel cutout of the test sector was loaded. The list fixes a pre-registered pixel-location test for TIC 207109417 (test sector 97, one sector): does the missing light of an unconfirmed periodic signal, already seen in the public QLP light curves, lie at the target star or at a Gaia neighbour? The note describes the rule (an edge-artefact barrier, an empirical gate from pseudo-ephemerides, classes from a position statistic, critical Gaia neighbours on a fixed grid of target positions, rule variant S chosen by a criterion fixed beforehand), the frozen inputs, the pre-tests as registered model frequencies, and discloses the decisions taken after interim results, the weak sensitivity in loud noise, the differences to the sister packages and the review history. The QLP light curve of sector 97 was loaded earlier for a held-out light-curve test with a public result (doi:10.5281/zenodo.23895647); the pixel rule was fixed after that result and is not blind with respect to it, and the pixels contain the same photons as the light curve. No release file exists, the pixel cutout of sector 97 has not been loaded, and there is no result. A registered test is not a confirmation: nothing here is a detection, a candidate or a validated planet. Supplement: the hash list, the files it lists (German rule text, programs, Gaia query answers and derived table, ephemeris, pre-test results and logs, self-test and kernel-test logs), names and digests of the public PRF models and search-sector cutouts, and instructions to verify them.
