Fixtures (organizations, rosters, ciphers) are independent building blocks that never reference each other. A preset composes them together and defines cross-cutting relationships like folder assignments and favorites. Presets can reference fixture files, generate data inline, or mix both. See docs/architecture.md for the full architecture guide.

Presets

Presets wire everything together. Org presets compose org + roster + ciphers; individual presets compose a single user + vault data. Organized by purpose:

Folder	Purpose	CLI prefix	Example
`features/`	Test specific Bitwarden features (SSO, TDE, policies)	`features.`	`--name features.sso-enterprise`
`qa/`	Known users, groups, collections, and permissions you can point a client to	`qa.`	`--name qa.enterprise-basic`
`scale/`	Production-calibrated density presets for performance testing	`scale.`	`--name scale.md-balanced-sterling-cooper`
`individual/`	Individual user accounts (no organization)	`individual.`	`--name individual.premium`
`validation/`	Algorithm verification for seeder development	`validation.`	`--name validation.density-modeling-power-law-test`

For the full preset catalog with per-preset details, see docs/presets.md.

For verification queries used during density development, see docs/verification.md.
