Eighth slice. Quick search wasn't contiguous — its functions sat on both
sides of the cheatsheet and password-history modals (lines 725-1104). Rather
than a fiddly non-contiguous cut, the whole overlay cluster is extracted as
one byte-identical block: js/app.overlays.js (quick search + cheatsheet +
password history). Pure declarations, no top-level side effects → loads
before app.js; all state/api/Bridge/render/decryptPwd refs resolve via shared
global scope at call time.
- Byte-for-byte identical; syntax OK on all nine app parts; 62/62 tests green.
- index.html + BuildAssets whitelist + harness APP_PARTS updated.
app.js: 11936 → 9170 lines (8 modules extracted, ~2770 lines). Load order:
argon2 → crypto → totp → favicon → import → backup → health → overlays →
app → sync.

Seventh slice of the app.js split. Moves the vault-health dashboard
(computeHealthCache, healthScoreBand, renderHealthDashboard/Section,
openEntryForFix, entryAgeDays + scoring consts) to js/app.health.js. Pure
declarations, no top-level side effects → loads before app.js. Uses
computeStrength/decryptPwd/state/api via shared global scope at call time.
- Byte-for-byte identical extraction; syntax OK on all eight app parts.
- auditCache/auditFilter sit in this var block but drive the separate
Audit-log viewer in app.js — they ride along and resolve cross-file via
shared scope (documented).
- index.html + BuildAssets whitelist + harness APP_PARTS updated.
- 62/62 tests green.
app.js: 11936 → 9545 lines (7 modules extracted).
NOTE: quick search is NOT contiguous (interleaved with cheatsheet +
history-modal code, lines 886-1063), so a clean byte-identical extraction
isn't trivial — deferred.

Sixth slice of the app.js split. Moves the favicon fetch/cache section
(faviconHost, saveEntryIcon, ensureEntryFavicon, backfillFavicons,
clearAllFavicons) to js/app.favicon.js. Pure declarations, no top-level
side effects → loads before app.js.
- Code moved byte-for-byte; no duplicate const; syntax OK on all 7 app parts.
- NEW: js/tests/favicon.test.js — 7 tests for faviconHost, the pure
URL→validated-hostname function that decides which domain is sent to the
DuckDuckGo proxy (a bug there leaks the wrong host). Covers scheme/www/
path/port stripping, non-hostname rejection, malformed dotting, unsafe
chars, and the 253-char DNS cap.
- Fixed an inaccurate source comment surfaced by the tests: it claimed raw
IPs "stay valid", but the TLD rule /\.[a-z]{2,}$/ rejects a numeric final
label, so IPs get no favicon lookup (fine). Test pins the real behaviour.
- Suite: 55 → 62 tests, all green. Assets regenerated (8 ordered JS files).
app.js: 11936 → 9790 lines (6 modules extracted).

Fifth slice of the app.js split. Moves the scheduled encrypted-backup
feature (config, retention, runAutoBackupNow/runAutoBackupIfDue) to
js/app.backup.js. Pure declarations + two consts, no top-level side effects
→ loads before app.js; uses encryptExportPayload (app.import.js), Bridge,
api, state via shared global scope at call time.
- Byte-for-byte identical extraction; no duplicate const; no top-level
backup reference left in app.js; syntax OK on all six app parts.
- index.html + BuildAssets whitelist + harness APP_PARTS updated; assets
regenerated (manifest embeds all 7 ordered JS files).
- 55/55 tests green.
app.js: 11936 → 9900 lines — now under 10k. Five modules extracted
(~2000 lines): argon2 → crypto → totp → import → backup → app → sync.

Fourth slice of the app.js split. Moves TOTP (base32Decode, generateTOTP,
parseOtpAuthUri) plus the TOTP-secret and custom-field AES-GCM wrappers to
js/app.totp.js. Loads before app.js (pure declarations), after app.crypto.js
(uses encryptPwd/decryptPwd). Also called by app.import.js and app.sync.js
via shared global scope.
- Byte-for-byte identical extraction; no duplicate const; syntax OK on all
five app parts.
- NEW: js/tests/totp.test.js — 13 tests including the 5 RFC 6238 Appendix B
reference vectors (generateTOTP reads Date.now(), so each case stubs the
sandbox clock to the vector's fixed time), base32 decode edge cases, and
parseOtpAuthUri. Extraction AND new coverage in one slice.
- Suite: 42 → 55 tests, all green.
- Assets regenerated (manifest now embeds all 6 ordered JS files:
argon2 → crypto → totp → import → app → sync); also fixes the previous
import commit's not-yet-rebuilt manifest.
- Delphi build artifacts (*.vrc, *.$manifest) gitignored.
app.js: 11936 → 10138 lines (4 modules extracted, ~1800 lines).

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.

Second slice of the app.js split (after crypto). Moves the WebDAV sync
section to js/app.sync.js: transport (_webdavCall), buildSyncSnapshot,
applyRemoteSnapshot (merge + tombstone arbitration), runSyncNow, and the
sync settings UI.
- Byte-for-byte identical to the extracted block (verified before removal);
no duplicate const; no top-level sync reference left in app.js.
- Load order: AFTER app.js (unlike crypto, which loads before) because this
module has a top-level side effect — `Bridge.onWebdavResult = …` — that
needs Bridge/state/api already declared. Rule documented in CLAUDE.md.
- index.html + BuildAssets whitelist + harness APP_PARTS updated; assets
rebuilt to embed the new file.
- Safety net: the existing merge tests exercise applyRemoteSnapshot /
buildSyncSnapshot from the extracted file and stay green (42/42).
app.js: 11936 → 11256 lines (crypto + sync now separate).

First slice of the app.js split. Approach: ordered classic-script files
loaded via separate <script> tags (argon2.js → app.crypto.js → app.js),
NOT ES modules / a bundler. Classic scripts share one global lexical
environment, so consts/functions cross-reference across files exactly as
in the monofile — zero call-site rewrites, near-zero risk. Chosen over the
audit's esbuild/ES-module suggestion because the code is written entirely
in global scope (functions call each other by bare name everywhere).
- js/app.crypto.js: KDF (PBKDF2 + Argon2id), verifier, AES-GCM encrypt/
decrypt, key persist/restore. Verified byte-for-byte identical to the
original block before removal; no duplicate const across the two scripts.
- index.html + BuildAssets whitelist + test harness updated for the load
order. Harness CONCATENATES app.crypto.js + app.js (node:vm doesn't share
top-level const across separate runInContext calls the way browsers share
it across <script> tags); argon2.js stays a separate IIFE.
- Runtime-validated: rebuilt exe unlocks via quick-unlock and loads/decrypts
entries — the extracted crypto (restoreCryptoKey, verifierFromKeyHex,
decryptPwd) works from the separate file. 42/42 tests green.

Phase 2 of CODE_AUDIT §1.2 — live adoption of the Argon2id foundation.
Verified at runtime: a rotated account shows hash_algo=argon2id-v2 with
argon2_m=19456,t=2,p=1 in vault.db.
Server (never runs Argon2 — zero-knowledge, only stores/echoes params):
- DB: users.argon2_m/t/p columns (default 0 = PBKDF2).
- PM.Handler.Auth: HASH_ALGO_ARGON2 + param bounds, ReadArgon2Params /
AppendArgon2Params helpers. /register and /change-master-password accept
hashAlgo='argon2id-v2' + argon2:{m,t,p} and persist them; /login/challenge
echoes them. Verify path (VerifierToStoredHash/CheckVerifier) is
KDF-agnostic — the 64-hex verifier is SHA256-wrapped as for any -v2 scheme.
Client (app.js):
- state.argon2Params, cached from the challenge and persisted to
sessionStorage + the quick-unlock / PIN cold-start blobs (so a cold-started
session can still derive-from-password for reauth/rotation).
- Register + master-pw rotation derive with argon2id-v2 + ARGON2_DEFAULT_PARAMS
(OWASP m=19MiB,t=2,p=1) and send the params. Rotation re-encrypts the whole
vault under the new Argon2 key (natural migration point). Existing accounts
stay PBKDF2 until they rotate.
- Params threaded through every derive-from-password site (login, reauth,
recovery setup, change-pw current verifier). Cold-start verifier-from-raw-key
paths need no params (isDecoupledVerifierAlgo handles the -v2 wrap).
Tests: +2 param-contract tests (register<->login determinism, param
sensitivity). 42/42. Assets rebuilt to embed js/argon2.js.
Docs: CLAUDE.md auth-hash section rewritten (4 markers); CODE_AUDIT §1.2 +
table + plan marked done.

Two CODE_AUDIT items in one session.
§3.2 — Frontend regression net (js/tests/, 35 tests, node:test, zero deps):
- harness.js loads app.js (monofile, no exports) into a node:vm with browser
globals stubbed, surfacing internals via an export epilogue.
- crypto: deriveKeyAndVerifier (AES key == raw PBKDF2, cross-checked vs Node
pbkdf2Sync), legacy-vs-v2 verifier decoupling, encrypt/decrypt round-trip,
IV uniqueness, AEAD tamper/wrong-key.
- csv: parseCSV tokenizer, findColumn heuristics, Bitwarden/KeePass mapping.
- merge: applyRemoteSnapshot add/update/skip (LWW), tombstone delete,
resurrection arbitration (both NaN branches), local-tombstone veto,
additive folder merge. Only api() is stubbed; loadEntries/encryptImportEntry
run for real.
- Wired as a build gate in BuildAssets.ps1 (after node --check, bypass
PM_SKIP_TESTS=1).
§2.2 — Unify timestamps on UTC:
- Entry created_at/updated_at were written via Delphi FormatDateTime(Now)
= LOCAL, while deleted_at/tombstones use SQLite CURRENT_TIMESTAMP = UTC.
The tombstone-resurrection arbitration compared the two zones, skewing by
the machine's UTC offset even single-device.
- Add NowUTC/NowUTCStr to PM.Database, swap in at every entry/attachment
write site (Entries create/update/bulk, Attachments POST echo).
- No JS change needed: arbitration now compares same-zone values.
- Existing rows self-heal on next edit (no destructive migration).

Quick search (Ctrl+Shift+Q fill mode)
- Enter / left-click → full autofill (username + Tab + password), like
Ctrl+Shift+L.
- Shift+Enter / right-click → username only (new Delphi username-only
SendInput path via field=user; ExecuteAutofill AUsernameOnly param).
- Ctrl+Enter / Ctrl+click → password only.
- Copy mode (tray / palette) unchanged: Enter/left = password,
Shift+Enter/right = username.
- Clipboard fix: copy-then-minimise no longer wipes the just-copied
password — MinimizeToTray takes an AClearClipboard flag (False on the
quick-search copy path, driven by app/minimize?keepclip=1). The 30s
auto-clear still guards it.
- Right-click on a result row suppresses the native/custom context menu
(preventDefault + stopPropagation).
Editable custom-field combobox
- Option-backed custom fields (card brand, expiry year/month, etc.) now
render a custom editable combobox instead of a locked <select>: an
arrow drops a menu of ALL options (a native <datalist> filtered to the
typed text, which confused users), while the input stays freely
typeable for values not in the list. Storage shape unchanged.
- Outside-click closes the menu via the existing slideover mousedown
handler; item mousedown + preventDefault so blur doesn't race the pick.
Build safety
- BuildAssets.ps1 runs `node --check` on every embedded .js before
generating assets.res. A syntax error now aborts the asset build
(exit 1, file + line logged) instead of shipping a dead bundle that
only surfaces after a full Delphi rebuild. Node is optional: absent →
warn and continue.
