Thousand Sons: rules coverage (2026-10-02)

T-541, the first batch of T-542 (Jordan, 2 Oct, before sleeping: "add all special rules to units, all detachment rules, at the very least"). Made by node tools/coverage.js --faction "Chaos - Thousand Sons" from docs/data/unitfx.json, leaderfx.json, detfx.json and armyfx.json; each ability read on Wahapedia's 11th-edition pages and written in our own words. A report: the calculator reads the dice effects (units' own behind flags.json's "unitfx"); nothing here changes a published score or letter.

Statuses. Modelled: the dice effect is all of it. Partly: some of it is dice, the rest noted. Noted: nothing for the dice; where it would be, can't yet says what the engine lacks. Unread: not in our data yet. An effect that starts off in the calculator (a damaged bracket, a rare condition) is marked so; the player switches it on.

Totals

A datasheet counts as modelled when every ability on it is dice, partly when some are, noted when none are.

What's here. Every Thousand Sons datasheet in BSData's catalogue at our commit (the six Crucible characters aside), read against Wahapedia's 11th-edition page on 2 Oct, and the 9 detachments. Cabal of Sorcerers, the army rule, is in armyfx.json as a pick of the Ritual on the unit's target:

• Destiny's Ruin: re-rolled hit 1s, or all hits on a 10+.
• Twist of Fate: +1 AP, or +2 on a 12+.
• Doombolt and Temporal Surge: mortal wounds and a move.

The 2D6 Psychic test and its doubles aren't in the maths. Pact of Sorcery is noted.

Decisions taken alone.

• BSData lists Mortal Sorcery and Daemonic Illusions on almost every datasheet. They come from Changehost of Deceit and are noted as that detachment's.
• Sustained Hits D3 is set at 2, its average, and named so: the Lord of Change's Master of Magicks, the winged Daemon Prince's Aetherstride, and the Stave Abominus. The Tzaangor Shaman's D3 sacrifice bonus is set the same way.
• The Predators' Ensorcelled abilities need a target that another unit's psychic attack has already hit. They start off and are switched by hand.
• Re-rolls that widen start off with their condition named: Bringers of Change, Hunter of Souls against psyker characters, and Armoured Spearhead. Once-a-battle effects start off too: Twisted Sorceries and the Tome of True Names.

What the army needs next. First the Psychic test (the 2D6 roll, its doubles costing D3 mortal wounds) and Doombolt's mortal wounds. Then Sustained Hits D3 as its own number, and the effects of other units' psychic hits on a target.

Vocabulary gaps, by how many units need each

What the engine would need to model the rest, from each rule's can't yet and kind; a unit counts once per gap.
