Horiyot
Horiyot: 2
The opening sugya of Masechet Horayot, explaining why a mistaken ruling by the Sanhedrin that leads the community to sin requires a special communal korban, and how the law differs for Avodah Zarah and for the Kohen Gadol's own error.
Horiyot 3
Opens Maseches Horiyot's sugya on when someone who acted on an erroneous court ruling is exempt, and how the Sanhedrin's own involvement affects a national majority's liability.
Horiyot 5
Covers when the Sanhedrin's own error requires a personal sin-offering, who brings the communal offering when only some of the twelve tribes are affected, and the comparison to cases of mixed uncertainty.
Horiyot 6
Covers Rabbi Yehuda's view that each tribe counts as its own kahal, the special decree for intentional idol worship, and the dispute over the lost goat and bull on Yom Kippur.
Horiyot 10
Covers the Mashiach-kohen's sin-offering obligation, a tangent into tzaraas and impurity from magic or assault, and the stories of Tamar, Yael, and Ruth's surprising lineage from Balak.
Horiyot 7
Compares the Nasi's sin-offering obligation to the Kohen Gadol's, and the special offering required even when an idolatry prohibition wasn't fully nullified.
Horiyot: 8
Continues Masechet Horayot, examining why the Mishnah separates the communal sin-offering for Avodah Zarah from other transgressions, and extending the discussion to why the congregation isn't liable in the same way for entering the Beis HaMikdash while tamei.
Horiyot: 11
A Horayot sugya on which sin-offering a king or mumar brings, the definition of a mumar through cases like eating meat with milk or wearing shatnez, and the halachos of the shemen hamishchah used to anoint kings and Kohanim Gedolim.

Covers the tradition of who concealed the Temple's sacred vessels before its destruction, omens for future events, and the continuity of the Holy Ark across both Temples.
Horiyot 13
Covers the halachos of a kohen's ritual tearing for different relatives, the order of precedence among sacrifices (more frequent and holier come first), and ten things that harm memory in Torah study.
Horiyot 14
Covers the honor given to a scholar's children in seating, who may leave and return to the Sanhedrin's chamber, and the distinction between a 'Sinai' scholar (deep in sources) and an 'Oker Harim' (sharp in logic).
