Index

# Search

One index over everything published here: 21 instruments, 97 glossary definitions, the research notes, the per-suite methodology pages and the observatory. It is generated from the built pages themselves, so it can only surface what actually exists — there is no separate marketing copy behind it.

Search runs entirely in your browser; nothing you type is sent anywhere. Try an instrument name (*feed auditor*), a measured quantity (*staleness*, *[spread regime](https://hadalinstruments.com/glossary/spread-regime/)*), or a term you met somewhere else and want defined (*[last look](https://hadalinstruments.com/glossary/last-look/)*, *[adverse selection](https://hadalinstruments.com/glossary/adverse-selection/)*).

The search index is not present. It is generated by Pagefind after `npm run build` and does not exist on the dev server.
