Hayz
Hayz is an accidental fortitude awarded when a planet satisfies three conditions at once: it agrees with the chart's sect, it stands on the hemisphere proper to that sect, and it occupies a sign of its own gender. It means a planet is entirely at home in its circumstances.
The fuller picture
Three separate questions have to come out the same way. Is the planet of the chart's own sect — a day planet in a day chart, a night planet in a night one? Is it on the side of the horizon proper to that sect? And is it in a sign of its own gender, with the masculine planets in the masculine signs and the feminine planets in the feminine ones? All three yes, and the planet is in hayz. Exactly two, and the older term is halb, a partial version of the same fortitude that is worth less and still counts for something. One or none, and there is nothing here to report.
That three-part structure is the whole reason to keep hayz and sect apart, and they are routinely run together. Sect is one of the three questions hayz asks. A planet can agree with the chart's sect perfectly and fail hayz on either of the other two, and a planet in hayz is necessarily in sect but the reverse does not follow. The two get confused partly because they are reported next to each other, and partly because a chart's sect is the more familiar idea, so the word people reach for tends to be the one they already know.
Something worth being straight about: hayz is not part of the modern practice this glossary otherwise follows. It is a Lilly and Bonatti fortitude that our engine carries, and the word appears nowhere in the material we have worked through — the only mentions anywhere in our corpus of that source are notes about a chart data payload, not about doctrine. What the source does carry is a sickness rule graded on exactly these three axes, put to the two malefics: Mars in a masculine sign, oriental and above the horizon, or Saturn in a feminine sign, occidental and below it, each does more harm. Same three questions — sign gender, side of the horizon, posture relative to the Sun — read as severity rather than as comfort. That is as close as the practice gets, and it is not the same rule.
Two practical notes. The fortitude is small, and it is a fortitude of circumstance rather than of capacity: a planet in hayz is comfortable and operating in conditions that suit it, which says nothing about whether it holds any dignity in the zodiac. A peregrine planet can be in hayz. And it says nothing about whether the matter asked about comes to pass, which still turns on the contacts between the significators.
In your chart
The judgment engine tests hayz for each of the actors in your question from three inputs — the chart's sect, which side of the horizon the planet stands on, and the gender of its sign — and records it as a small supporting piece of evidence, naming it as hayz where all three conditions hold and as halb where exactly two do. The same fortitude is credited to the planet's accidental score behind its dossier row, where it is deliberately assessed on the stricter all-three test only.
