Iron Hands: rules coverage (2026-10-02)

From reports/tiers/2026-10-02-iron-hands-coverage.md , rendered when the site is built.

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 "Imperium - Adeptus Astartes - Iron Hands" 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.

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

What's here. The Iron Hands' own 2 datasheets in BSData's catalogue at our commit (Caanok Var, Iron Father Feirros), read against Wahapedia's 11th-edition Space Marines page on 2 Oct, and their detachment, Hammer of Avernii (in BSData's Space Marines list, named with --dets). The shared Space Marine datasheets and Oath of Moment come with the Space Marines' report.

Decided alone. Caanok Var's Cold and Calculating (Lethal Hits against monsters and vehicles, Sustained Hits 1 against the rest) stays in leaderfx.json for the unit he leads. Feirros's Master of the Forge (a vehicle within 3" heals and hits better) is another unit's buff, so it's noted. "Inspiring Commander" is in BSData only.

What the army needs next. Buffs from a character to a nearby vehicle (Master of the Forge), and Battle-shock as a dice result (Medusan Roar).

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.
