 ## Key design decisions

 ## Conventions
 
 - Tests use fast Argon2id params (m=256, t=1, p=1) so they don't take forever.
 - Test JPEGs are generated synthetically via `make_test_jpeg()` — no binary test fixtures.
-- Entry IDs are random 8-char hex strings.
+- Item IDs are random 8-char hex strings.
 - Git history is preserved as an audit log — no squashing.
 - The CLI shells out to `git` for sync — no libgit2/gitoxide dependency.
