Deathwatch: rules coverage (2026-10-02)

From reports/tiers/2026-10-02-deathwatch-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 - Deathwatch" 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 Deathwatch's own 11 datasheets in BSData's catalogue at our commit, read against Wahapedia's 11th-edition Space Marines page on 2 Oct, and their detachment, Black Spear Task Force (in BSData's Space Marines list, named with --dets). Mission Tactics, their army rule in this list, is in armyfx.json as partly: a pick of the turn's tactic, Furor (Sustained Hits 1) or Malleus (Lethal Hits). Purgatus's Precision on critical hits isn't a mod yet.

Decided alone.

What the army needs next. Precision on critical hits (Purgatus Tactics), keyword exclusions in an effect's target (Death to the Alien), and the special-issue ammunition Stratagems.

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.
