Death Guard: 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 - Death Guard" 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 Death Guard datasheet in BSData's catalogue at our commit (the Crucible characters aside), read against Wahapedia's 11th-edition Death Guard page on 2 Oct. That includes the Legends war engines the page carries, and the 10 detachments. Nurgle's Gift, the army rule, is in armyfx.json:

• Afflicted's -1 Toughness, written as +1 Strength (as Dread Mob's "target -1 T" pick already is). It starts off, because Afflicted is a range check the player makes.
• The Plague as a pick: Skullsquirm Blight is -1 to be hit in melee by an Afflicted attacker; Rattlejoint Ague is +1 AP into an Afflicted target; Scabrous Soulrot changes Move, Leadership and OC, which aren't dice.

Decisions taken alone.

• Effects that need an Afflicted target are written with that condition and start on, as most attacks a Death Guard unit makes are within a Contagion Range. That covers Blistering Fusillade, Diseased Malice and Eye of Affliction.
• Once-a-battle effects start off (the Pestilent Familiar).
• Mortarion's Lord of the Death Guard abilities (a move, fighting on, shooting back) aren't dice, so they're noted.

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.
