This archive tracks four layers. A record present in 4 of them (HH, AoI, M41, IND) is silent in the rest, and says so.
The Horus HeresyM30–M31
chaos
Word Bearers compliance, lost and gone rogue
A world the Word Bearers took during the Great Crusade and then lost contact with. Between the Dropsite Massacre and the Battle of Calth, three of the Legion's own — marooned here and left to rot — found ancient xenos blades on it, went mad, and made the planet theirs: the population enslaved, an army of mutants bred from corrupted gene-seed, and ghosts walking the surface. Zardu Layak came for the blades and left with three of them.

www.warhammer-community.com/en-gb/articles/1eg0z9ov/new-word-bearers-novel-zardu-layak-the-crimson-apostle-announced/ 'he must travel to a forgotten world and retrieve a weapon that will give him the strength he requires – the malign Anakatis Blades. But ghosts plague the surface of Helwain'. Named again in the Sunday Preview of 05 Apr 26 ('he headed to Helwain to seek the legendary Anakatis blades') and the Saturday pre-orders post of 11 Apr 26 ('the forgotten world of Helwain').
allegiancehigh
wh40k.lexicanum.com/wiki/Zardu_Layak §Heresy, citing Zardu Layak: The Crimson Apostle ch. 3-4 — 'the Word Bearers had lost contact with the world of Helwain, which the Word Bearers had conquered during the Great Crusade' and 'the world had gone rogue under his old comrade Hebek, who had used a cursed Anakatis Kul blade to enslave the population'.
classlow
editorial, NOT a citation: no permitted source gives Helwain a world type. Lexicanum has no article for the world and the three Warhammer Community posts call it only 'a forgotten world' whose 'surface' is 'plagued' by ghosts. What canon does say is that it was a Great Crusade compliance with a population still alive on it to be enslaved (Lexicanum, Zardu Layak §Heresy) — so `temperate`, this dataset's neutral inhabited-world palette, which asserts nothing. Explicitly NOT `dead` (it is populated and has a thick atmosphere), NOT `daemon` (canon never calls it a daemon world; that palette is reserved for Signus Prime, Medrengard and the Eye), NOT `ice`/`desert`/`death`/`feral` (no terrain or colour word exists anywhere to support one). Step 5a2 asks what the world LOOKS like and the only published depiction is the novel's own cover art — bare dark crags drowned in pale freezing haze — but that is one scene on one world, not a planetary type, and the class string is shown to readers as 'temperate world', so the least-claiming true label was taken instead of the prettiest render.
segmentumhigh
[RECORD LOST] — no permitted source places Helwain. Lexicanum carries no article for the world, and the three Warhammer Community posts name no segmentum, sector, subsector, system or neighbour for it. The record therefore claims no segmentum rather than inheriting one from the Word Bearers' theatre.
gposlow
inferred: Helwain has a name, a book and no published geography of any kind — not a segmentum, not a sector, not a bearing, not even a campaign theatre it can honestly be attached to (the novel is a detour away from the Legion's war, not part of it). So the record claims no segmentum and takes the generator's rim_xy('helwain') point on the unsurveyed rim, r=451.1 from the core, with the Z the zPolicy computes for it. The position carries NO information and must not be read as one: it exists so a catalogued book resolves to the world it is actually set on. Upgrade it the day GW places Helwain.
no-system-surveyhigh
Deliberately no data/systems/helwain.json. Canon enumerates NOTHING about the system: no star, no spectral class, no sibling body, not even a body count or a system name distinct from the world. An authored survey could only invent a star — and normaliseSystem() writes a spectral class of 'G' for any authored file that omits one, which is exactly the assertion the synthesiser refuses to make (loader.js sets doc.star.class = null on purpose). The app's synthesiser draws Helwain from this record's `class` and seed = hashId('helwain') % 97 = 95, so the reader still gets a globe and the data still says [RECORD LOST] about the star.
