username is no longer stored cleartext. New columns username_enc/username_iv
(AES-GCM under the vault key, same as encrypted_password). Search/sort/render
stay client-side, so the field is decrypted at loadEntries into e.username in
memory — everything downstream is unchanged. Full-strength random-IV AES-GCM
(no searchable/deterministic encryption) precisely because search is
client-side.
Server (PM.Handler.Entries / .Auth / PM.Database):
- Schema: vault_entries.username_enc, username_iv.
- GET returns them; POST/PUT/bulk-import read + persist them; master-pw
rotation re-encrypts them under the new key (UPDATE + loop).
- ?q= server search drops `username LIKE` (ciphertext won't match; frontend
searches client-side anyway).
Client (app.js / app.import.js):
- loadEntries/loadTrash decrypt username_enc → e.username (fallback to
cleartext for un-migrated rows).
- withEncryptedUsername(obj): write choke point — encrypts obj.username into
username_enc/username_iv and blanks the cleartext. Wraps every POST/PUT
body: saveEntry, soSave, duplicateEntry, moveEntryToFolder, addTagToEntry,
batchMove/AddTag, encryptImportEntry (import + sync-apply).
- doChangeMasterPassword re-encrypts username under the new key.
- migrateUsernamesAtRest(): one-time sweep at enterApp, PUT-re-ships rows that
still carry cleartext username so the DB gets scrubbed (bumps updated_at
once; plaintext unchanged so devices converge).
site/title/tags stay cleartext (same pattern later — see memory note). +1
merge test (username encrypted on import). 65/65.
NOT compiled/tested at runtime (Delphi) — large multi-handler change; rebuild
BuildAssets + PMServer and test create/edit/rotate/import/sync + verify the
DB shows no cleartext username.

Third slice of the app.js split. Moves the encrypted export container,
CSV/JSON import parsing (parseCSV, findColumn, parseEntriesFromCSV,
parseEntriesFromJSON), and the doImport/doExport/doExportCSV flows to
js/app.import.js. encryptImportEntry moves here too (also called by
app.sync.js — resolved via shared global scope at call time).
- Byte-for-byte identical to the extracted block; no duplicate const;
no top-level import ref left in app.js.
- Load order: BEFORE app.js (pure declarations, no top-level side effects),
alongside app.crypto.js. Full order: argon2 → crypto → import → app → sync.
- index.html + BuildAssets whitelist + harness APP_PARTS updated.
- Safety net: the 14 CSV tests exercise parseCSV/parseEntriesFromCSV from
the extracted file and stay green (42/42).
app.js: 11936 → 10253 lines (crypto + sync + import now separate, ~1700
lines moved into 3 modules).
NOTE: assets.res not regenerated here (needs brcc32/Delphi) — run
BuildAssets before the next Delphi build to embed js/app.import.js.
