graphsync.IndexDoc/BackfillFromBrainDir and wiki.LoadInventory/ RebuildIndex read notes by path (os.ReadFile, os.Open, os.ReadDir + open). A symlinked note put the target's title, aliases and wikilinks into the knowledge graph, the wiki inventory (and the LLM prompts built from it) and wiki/index.md; a FIFO hung each read. - graphsync: IndexDoc and the backfill read through brainfs; the backfill walks with WalkRegular, skips a missing root and aborts on any other walk error, including a symlinked root. - wiki: LoadInventory lists type dirs with the new brainfs.ReadDirRegular (every component a real dir, regular files only) and reads frontmatter through the root; a symlinked type dir is an error. RebuildIndex reads first sentences through the root. - brainfstest's outside file now carries the sentinel in frontmatter title and aliases, a heading and a wikilink, so extractors that ignore the body are tested too.
