Suchi (Sanskrit sūcī सूची: a needle, and by extension the index — the list that points). A repo that reads itself: its own tree drawn from its own file paths, its own markdown grouped by its own folders, and EACH PAPER'S TITLE TAKEN FROM THE PAPER'S OWN FIRST HEADING — never a string typed beside it, never a lookup table, so a document renamed in its own first line is renamed everywhere at once. A folder becomes a group whose label is derived from the folder name; the repo root sorts first whatever it would do alphabetically. The house's one-line italic gloss under a heading becomes the blurb where it is there and null where it is not — a badge line is not a gloss and neither is a bold one — and a file with no heading at all falls back to its own filename rather than being invented a title or dropped from the index. A paper that declares itself a MIRROR-class self-map is known by the phrase in its own text and never by its filename, so a future self-map inherits the rule by saying so. THE WATER OWNS NEITHER THE BUILD TOOL NOR THE GLOB: it declares the glob's RESULT — path to raw text — as a host surface of one verb and supplies none of it, so the same repo handed over by a build-tool host or a filesystem host or an in-memory fixture yields byte-identical answers. A sūcī points at what is there; it is not the thing, and it holds no copy of the thing.
Sanskrit सूची (sūcī, a needle, and by extension a list or index, the thing that points); a needle threads and an index points, and the name here keeps only the pointing.
The thing that points at what is there rather than copying it. An index built from a repository's own headings and paths, so a document renamed in its own first line is renamed everywhere the index shows it.
