A mechanical prettier --write over server/src, server/tests, server/scripts and shared/src with the workspaces' .prettierrc; nothing but layout and import order changes, and every file keeps the same set of imports. shared is formatted throughout and its format baseline is empty. The server baseline keeps the 35 files that Prettier would grow past their lint:size limit (they need a split first, which is not a formatting change), and the generated entity files stay as their generator writes them.

|
|
* journal_mode is stored in the database file header, so it is not a per-process
|
|
* setting: whichever process opened the file last decides the mode for all of
|
|
* them. reset-admin.js and scripts/migrate-encryption.ts open the same file and
|
|
* therefore read the same two variables — they cannot import this module (they

|
* are standalone scripts and src/ is not in the image), so keep the three in
|
|
* sync when the defaults change.
|
|
*
|
|
* The returned values are read back from the engine rather than echoed from the
|
|
* config, so a mode SQLite refused shows up as what it really is — an in-memory
|
|
* database stays MEMORY however hard you ask for WAL.
