§1

What is established

First-party

The systems layer is unusually complete for a launch week, because the store description is unusually detailed. Possession and the Spark, the Grinder economy, the cursed elevator, the Corrupted detection model, the Rot's depth scaling and the Outpost rebuild all come from the publisher's own text. The Outpost screenshot adds a working example of room progression, and the combat screenshots supply the HUD.

The structured record is stronger still: 21 developer-listed 1.0 additions, 12 dated announcements with event types and figures, a 7-row specification, a 16-row language table and publisher-written terminology in nine languages. Every one of those five datasets is reproduced in full on its own sheet — Demo vs 1.0, Official updates, PC requirements and Languages — rather than summarised once here and left unlinked.

What nobody has published

5 open items
Gaps as of 8 August 2026
MissingWhy
Enemy, boss and biome namesThe developers name none of them, including in the scope list that adds them
NumbersNo stats, drop rates, upgrade costs or quota values released
MapsNo spatial data exists; the Deep Layers are procedurally generated
AchievementsNone configured on the Steam app
Patch notesNo post-launch patch has shipped yet

The same five gaps are printed as ruled rows on Home, with the same weight as the confirmed data around them, because a blank line marked as blank is more useful this week than a page that quietly avoids the question.

Why other wikis look bigger

Snapshot, 8 Aug 2026

The largest competing GRAIN ROT wiki publishes 53 sitemap URLs, of which 44 are English content routes grouped into nine hub families — enemies, maps, tier lists, tools. Read the pages and most restate the same store description this ledger works from, because there is no other source yet. The wikis that do publish enemy names state in their own pages that individual names, attack patterns, weaknesses and any boss roster are not officially documented and should be treated as unverified.

This ledger grows the way the game does: when the first patch notes land, the log on Official updates gets its next row, and when the developers name a single enemy, that name gets a sheet of its own rather than a guess folded into this one.
