r-zakarya f97e44768a fix(desktop): stop pushing a snapshot that changed nothing
Measured on the phone, opening a cached vault: 121 ms to read the sealed file,
14 ms to display it - and then 5718 ms decrypting a snapshot it already had.

The cause is upstream. A sync pushes unconditionally at the end, and the push
is never a no-op: the container is re-encrypted with a fresh salt and IV, so an
identical vault produces completely different bytes. On Gitea that is one more
commit and a new blob sha, so every other device sees a "new" snapshot and pays
a full key derivation to arrive back where it started. It also grew the
repository on every sync that changed nothing, which is the history cost the
plan warns about.

The merged state is now compared against what was pulled, as plaintext -
the only place equality is observable - ignoring snapshot_at, which changes by
construction. Equal means the push is skipped and the sync still counts as done,
timestamp included: having nothing to write is a success, not an absence.

The comparison is deliberately strict. A false negative costs one commit; a
false positive would silence a push that carried a change and lose it for the
other devices. Four tests fix where that line sits, including a modified
updated_at (which arbitrates the merge elsewhere) and a tombstone (a deletion
that has to propagate).

r-zakarya c1d0eb3891 feat(desktop): sync to a private Gitea repo, chosen by the URL
Same discriminant as the Android client - "/api/v1/repos/" in the URL - so one
address tells both ends which transport to speak, and nothing new appears in
Settings beyond a placeholder and a warning.

The bridge stays shared. Three things differ, and they are confined: the header
is "token <PAT>" rather than Basic (Gitea answers a silent 401 to the other),
a PUT carries a JSON envelope with the file base64-encoded inside it, and the
connection test uses GET because the contents API does not answer HEAD.

The sha does the ETag's whole job. It comes back from the pull, rides in the
PUT body instead of an If-Match, and a stale one earns a 409 - handled exactly
like WebDAV's 412, by re-running pull->merge->push so the other device's
changes are folded in rather than clobbered. On a first push `sha` is OMITTED
rather than sent empty: Gitea reads its presence as "replace that exact
version". `branch` is omitted too, so the repo's default is used instead of a
name we would be guessing.

A failing PUT now reads its response body: Gitea explains a 409 or a 422 there,
and without it the error was just a number.

The test button checks the SHAPE of what came back, not only the status. A URL
one path segment off answers 200 with valid JSON that is not a file - which
would otherwise surface much later as "wrong sync password" and send you
looking on the wrong side. Four tests cover that parsing, including the
line-wrapped base64 Gitea sends and the array an accidental directory URL
returns.

r-zakarya 829056f1fa fix(import): normalize timestamps to the DB format at the import door
vault_entries uses SQLite's space-separated UTC format everywhere, and both
sorting and sync last-write-wins compare the strings lexically — so a foreign
JSON import carrying strict-ISO 'T'/millis/Z/offset timestamps would slot in
with a different format and subtly break ordering and merge arbitration.
normalizeImportTimestamp converts any ISO-ish variant to 'YYYY-MM-DD
HH:MM:SS' UTC (bare strings treated as UTC, garbage -> '' = server stamps
now). +1 unit test (69 total).

r-zakarya d583a3f7d3 refactor(js): extract attachments, autofill, unlock modules from app.js (3.1)
app.js 9363 -> 7962 lines. Three new classic-script modules:
- app.attachments.js (250): blob crypto + upload/download UI, pure
  declarations, loads before app.js
- app.autofill.js (276): Win32 combos, title->entry matching, picker,
  pure declarations, loads before app.js
- app.unlock.js (907): Quick Unlock + PIN + recovery code grouped (same
  "enter without master pw" theme); assigns Bridge.onPinResult /
  onQuickUnlockResult at top level so it loads AFTER app.js, like app.sync.js

Audit viewer stays in app.js (only 65 lines, not worth a file). Clipboard
bridge helpers stay too (were interleaved in the quick-unlock section but
unrelated). Registered in BuildAssets whitelist + index.html + APP_PARTS.
Verified in-app: quick unlock cold-start, attachment upload/download.

r-zakarya a42e4b205d feat(entries): encrypt template at rest, guided tour, import fixes, cleanup
Batched session work sharing app.js / index.html / Entries.pas, so it can't
split cleanly without interactive hunk staging.

- feat: encrypt `template` metadata at rest (template_enc/iv, added to
  ENCRYPTED_META_FIELDS). withEncryptedMeta skips an absent template key so
  partial re-ships (add-tag, move-to-folder) don't wipe it via LHasTemplate.
  Cleartext column kept as migration fallback. +3 unit tests.
- feat: first-run guided tour ("How it works") — spotlight + bubble, no GIFs,
  re-launchable from Settings, seen-flag in DPAPI prefs.
- fix(import): preserve original created_at on restore (was stamped to import
  time); restore entry icons on overwrite (PUT ignores icon_b64).
- fix(settings): correct clipboard-privacy copy (already excluded from Win+V);
  PIN text 4-6 -> 4-12; reorder Set-PIN above unlock-method; move tray/startup
  toggles to General; dedicated backup-password button + warning status; tab icons.
- chore: remove dead legacy monolith (app-legacy.js, index-legacy.html,
  style-legacy.css) + unused passkeyBtn stub.
- docs: full-source review (CODE_AUDIT 6b), template + favorite/pinned notes.

r-zakarya 92ed153bc0 fix(sync): surface attachment/folder restore failures (audit 2.3)
applyRemoteSnapshot swallowed attachment + folder restore errors in silent
catch blocks. Count them (attFailed/folderFailed) and warn in a toast after
the sync summary. These don't abort the push (the entry synced, only its
attachment/folder didn't) unlike a failed entry import.

r-zakarya 6556ce8dea feat(crypto): encrypt site/title/tags at rest too (CODE_AUDIT §1.3)
Extends the username-at-rest scheme to site, title and tags — the last
searchable metadata still stored cleartext. Same design: dedicated
<f>_enc/<f>_iv columns (AES-GCM under the vault key), decrypted at load into
e.<f>, so client-side search/sort/render/favicon/autofill-match are unchanged.
Full-strength random-IV AES-GCM (no searchable encryption) because search is
client-side.

Generalized the helpers over ENCRYPTED_META_FIELDS = [username, site, title,
tags]:
- withEncryptedUsername → withEncryptedMeta (encrypts all four, blanks
  cleartext) — wraps every POST/PUT body.
- decryptEntryUsernames → decryptEntryMeta (decrypts all four at load).
- migrateUsernamesAtRest → migrateMetadataAtRest (sweeps any field still
  cleartext, live + trash).
- doChangeMasterPassword re-encrypts all four under the new key.

Server (Entries + Auth + Database):
- Columns site_enc/iv, title_enc/iv, tags_enc/iv; GET emits them (new
  AddNullableField helper); POST/PUT/bulk read+persist (BindNullable helper);
  rotation UPDATE re-encrypts them.
- Removed the server "Site required" validation (site='' when encrypted — the
  client enforces it) at POST/PUT/bulk.
- ?q= server search neutralized (site+username ciphertext → LIKE useless; the
  frontend never sends ?search=).

Tests: merge assertions updated to decrypt site (encrypted on import). 65/65.

username was runtime-validated earlier; site/title/tags NOT yet compiled/
runtime-tested (Delphi) — large multi-handler change. Rebuild BuildAssets +
PMServer, then create/edit/dup/move/tag/import/rotate and verify the DB shows
no cleartext site/title/tags (and the app still renders/searches).

r-zakarya 69fb2b10dd feat(crypto): encrypt username at rest (CODE_AUDIT §1.3)
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.

r-zakarya c58424d58c feat(sync): include avatar in sync snapshot + auto-backup (multi-device)
The profile picture (users.avatar_b64, cosmetic/unencrypted) travelled only
in the manual export. Now it's also in buildSyncSnapshot and the auto-backup
container, so a new device / a restore picks it up.

- Restore is ADDITIVE (mirrors the import path): applyRemoteSnapshot adopts
  remote.avatar_b64 only when the local device has no avatar — never clobbers
  a locally-set picture. No per-avatar timestamp to arbitrate, so changing an
  existing avatar doesn't propagate (cosmetic, accepted).
- +2 merge tests (adopt-when-empty, don't-clobber-when-set). 65/65 green.
- Server /avatar endpoint unchanged (already accepts {avatar_b64}).

Closes the avatar item of CODE_AUDIT §4.

r-zakarya dd86b2bd23 perf(crypto): derive Argon2id via argon2idAsync (unfreeze unlock UI)
deriveKeyBytes now calls NobleArgon2.argon2idAsync instead of the sync
argon2id, so it yields to the event loop periodically and the busy/unlock
spinner keeps animating instead of freezing ~0.65 s during login, register,
and master-pw rotation. Same result (both RFC-9106-verified); all callers
already await deriveKeyBytes so no call-site changes.

- Re-vendored js/argon2.js to export argon2idAsync alongside argon2id
  (re-bundled from @noble/hashes@2.2.0; both variants pass the RFC 9106 §5.3
  vector). 27KB → 29KB.
- Added a sync/async parity test. 63/63 green.
- Closes the last open item of CODE_AUDIT §1.2.

NOTE: argon2.js grew — run BuildAssets to re-embed it before the next
Delphi build.

r-zakarya 9e424efaf4 refactor(js): extract quick-search overlay cluster from app.js (§3.1)
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.

r-zakarya b44b05118e refactor(js): extract vault-health module from app.js monofile (§3.1)
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.

r-zakarya a7ad81c708 refactor(js): extract favicon module + add faviconHost tests (§3.1)
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).

r-zakarya 4fd768d4cf refactor(js): extract auto-backup module from app.js monofile (§3.1)
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.

r-zakarya 5fc07aed7a refactor(js): extract TOTP module + add RFC 6238 tests (§3.1)
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.

r-zakarya 97a19836a0 refactor(js): extract import/export module from app.js monofile (§3.1)
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

r-zakarya 2d309f8988 refactor(js): extract sync module from app.js monofile (§3.1)
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).

r-zakarya ca8081987d refactor(js): extract crypto module from app.js monofile (§3.1 start)
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.
- Docs: CLAUDE.md "Découpage frontend" (pattern + rules), file map, tests

r-zakarya 5e88ad33d1 feat(crypto): adopt Argon2id (argon2id-v2) on register + master-pw change
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 +

r-zakarya 2bd0fcfbf8 feat(crypto): Argon2id KDF foundation (vendored, not yet adopted)
Phase 1 of CODE_AUDIT §1.2 — additive, no live account uses Argon2id yet.

- Vendor @noble/hashes@2.2.0 argon2id as js/argon2.js (esbuild IIFE exposing
  globalThis.NobleArgon2). Pure-JS, not WASM: CSP is script-src 'self' with no
  wasm-unsafe-eval, so WASM would require weakening it. Verified against the
  RFC 9106 §5.3 test vector. Server needs zero Argon2 (zero-knowledge: it only
  ever SHA256-wraps the client verifier).
- app.js: deriveKeyBytes(pwd, salt, algo, iters, argonParams) branches Argon2id
  vs PBKDF2; deriveKeyAndVerifier refactored around it. New markers
  HASH_ALGO_ARGON2='argon2id-v2' + ARGON2_DEFAULT_PARAMS (OWASP m=19MiB,t=2,p=1,
  ~0.65s/unlock). isDecoupledVerifierAlgo() generalises the decoupled-verifier
  rule to any '-v2' scheme so argon2id-v2 inherits it. AES key is still ALWAYS
  the raw KDF output → entries decryptable, legacy accounts untouched.
- index.html loads js/argon2.js before app.js; added to BuildAssets whitelist;
  test harness loads it into the sandbox first.
- Tests: +5 (RFC 9106 vector via vendored bundle, argon2 branch derives Argon2
  key not PBKDF2, decoupled verifier, AES round-trip under Argon2 key). 40/40.

r-zakarya d9397881dc test: add frontend unit suite + fix mixed local/UTC timestamps
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).
