Index

The content-oriented catalog of this wiki: every page, one line each, organized by category. This is the machine-facing counterpart to _Sidebar (navigation) and Home (landing page) — when answering a question, check here first to find the right page, then drill in. Updated on every ingest; see Wiki-Conventions for the maintenance rules.

Raw source: the nyx-os repository (kernel/, user/, AGENTS.md, git history) — see Wiki-Conventions#The three layers. Pages: 43 · Lines: ~11000 · Tracking: v6.4.363

Tip

This wiki's root is also an Obsidian vault — open this folder directly in Obsidian for graph view, backlinks, and outgoing links over these same files. See Obsidian vault in Wiki-Conventions.
