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 263799adcd fix(crypto): migrate trashed entries' usernames too (§1.3)
migrateUsernamesAtRest only swept state.entries (live rows), so a soft-deleted
entry kept its cleartext username in the DB until purge. Now it also fetches
+ decrypts the trash (GET /entries?deleted=1) and includes those rows in the
sweep. The PUT updates the row's fields without touching `deleted`, so the
entry stays in the trash; trashed rows aren't in the sync snapshot, so no
churn. Surfaced by a lingering cleartext username on a trashed test entry.

r-zakarya 58c1961dc0 docs: mark username-at-rest encryption runtime-validated (§1.3)
After rebuild + unlock, vault.db shows 0 cleartext usernames (54 entries,
43 username_enc); the migrateUsernamesAtRest sweep completed on its own.

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 2578ac0d06 fix(tray): drop "Welcome back" toast on tray-icon restore
Restoring from the tray popped a "Welcome back" toast every time — noise for
a routine action. Removed it from onTrayRestore; the auto-lock reset stays.
The login-success "Welcome back, <user>" toast is unaffected.

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 8e0e7fd330 feat(quicksearch): remap fill modes — left/Enter=password, right/Shift=full
Per user request, swap the quick-search click/key mapping so the common case
(fill just the password) is the plain left-click / Enter:

  left click  / Enter        → password only   (was: full user+Tab+pwd)
  right click / Shift+Enter   → full user+pwd   (was: username only)
  Ctrl+click  / Ctrl+Enter    → username only   (was: password only)

Keyboard mirrors the mouse. Copy-mode (tray/palette, no HWND target) shares
the same `mode`, so it shifts too: click/Enter copies password, Ctrl+click/
Ctrl+Enter copies username (right-click's 'full' has no copy meaning → pwd).
Updated the dynamic hint, the static index.html hint, and CLAUDE.md.

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.

app.js: 11936 → 9900 lines — now under 10k. Five modules extracted
(~2000 lines): argon2 → crypto → totp → import → backup → app → sync.

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
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.

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 4ffbd63893 fix(sync): bump updated_at on set-icon + folder-delete reassignment
Both UPDATEs mutated a synced column without touching updated_at, so the
change rode in the sync snapshot but other devices skipped it (last-write-
wins saw "not newer"). Now both SET updated_at = datetime('now') (UTC).

- POST /entries/{id}/icon (PM.Handler.Entries)
- folder delete → entries reassigned to 'All' (PM.Handler.Folders)

accessed_at stays exempt (read timestamp, not synced); bulk "clear all
icons" stays exempt (device-local favicon cache purge). Invariant documented
in CLAUDE.md.

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 +
table + plan marked done.

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).

r-zakarya 73e4e37f19 docs: document chunked file transport, busy overlay, VACUUM, shutdown, UI features
CLAUDE.md was missing most of this session's work. Added the gotchas a
fresh session most needs:
- Chunked JS→Delphi transport (_streamChunks) + the WebView2 URL-limit
  black-screen trap + the resolved-chunk stale-timeout hang (don't
  regress the clearTimeout in onFileChunkAck).
- Busy overlay helpers + the undefined-CSS-var trap (--bg-elev-3).
- Auto-VACUUM (SQLite never shrinks on DELETE).
- Clean shutdown / WAL (WM_QUERYENDSESSION).
- WebView2 nav race (cold-start black screen).
- node --check build gate.
- UI/data: profile avatar (users.avatar_b64 + /avatar), quick-search
  fill modes + username-only autofill + keepclip, editable custom-field
  combobox, settings search, password reveal on prompts.

r-zakarya ac909f4f09 feat: sync ETag concurrency + fix chunk-transfer hang + sync overlay + auto-VACUUM
Sync optimistic concurrency (ETag/If-Match)
- webdav GET captures the response ETag; PUT sends it back as If-Match so
  the server rejects (412) our write when another device changed the file
  between our pull and push. A 412 re-runs the whole pull→merge→push
  (bounded to 3) so the other device's changes are folded in instead of
  clobbered. Servers without ETags → empty etag → no If-Match → falls
  back to last-write-wins (no regression). onWebdavResult gained a 4th
  etag arg.

Chunked webdav PUT (big vaults no longer black-screen on sync)
- The whole encrypted snapshot base64'd into a single cmd://webdav/put URL
  blew past WebView2's cap → black screen once the vault grew (20MB of
  attachments). PUT bodies now stream through the file/chunk transport and
  commit via a new webdav/put-commit (reads the accumulated buffer).

Chunk-transfer hang fix (root cause of the stuck "Preparing…" sync)
- All chunked transfers (saveFile/writeFile/webdav PUT) share one
  reqId-keyed resolver. A resolved chunk's stale 30s timeout would later
  delete the CURRENT chunk's resolver and fire the wrong res(), leaving
  that chunk's await pending forever. Extracted a single _streamChunks()
  helper whose ack CLEARS the pending timeout, so resolvers stay strictly
  one-at-a-time. Also fixed _webdavCall referencing the Bridge-local cmd()
  from module scope (latent ReferenceError).

Sync busy overlay
- syncStatus() now drives the global busy overlay too, so a running sync
  blocks stray clicks (e.g. the auto-backup "Choose…" picker) and reads
  like the manual backup. The account-mismatch confirm hideBusy()s first
  so it's visible above the overlay.

Auto-VACUUM (reclaim space after deleting large attachments)
- SQLite never shrinks the file on DELETE, so deleting big attachments
  left vault.db bloated (35MB for 11 tiny entries). DB.CompactIfBloated
  VACUUMs when >20% of pages are free AND >~2MB is reclaimable — called on
  startup and after each attachment delete. A healthy small vault pays
  nothing. (Verified: 35MB → 695KB after the deletes.)

Rebuild: BuildAssets + F9 (UMainForm + PM.Database + PM.Handler.Attachments).

r-zakarya b367d031b5 style: define missing --bg-elev-3 / --accent-fg CSS variables
--bg-elev-3 was referenced (spinner ring, search-clear hover) but never
defined in either theme, so var(--bg-elev-3) with no fallback produced an
invalid declaration — that's why the busy spinner ring was invisible
until it was switched to --border. Define it as a real elevation step
above --bg-elev-2 in dark (#34343f) and light (#e3e3dd).

Also define --accent-fg (#fff) explicitly instead of relying on the
inline var(--accent-fg, #fff) fallback.

Audited used-vs-defined custom properties: the only remaining "undefined"
one is --strength, which is set at runtime by JS on the password-strength
bar (has a 0% fallback) — intentional, not a bug.

r-zakarya 48bb06c029 feat: rotation progress spinner + quick-unlock re-wrap on master-pw change
- doChangeMasterPassword shows the busy overlay while it re-encrypts the
  vault: "Re-encrypting vault…" → "Re-encrypting entries… N/total" →
  "Re-encrypting attachments… N/total", cleared in finally. A rotation on
  a big vault took tens of seconds with no feedback before.
- Quick-unlock now SURVIVES a master-pw change instead of being wiped.
  The blob stores the raw key (DPAPI-wrapped, no user secret), so it's
  re-wrapped in place with the new key/salt/iters/algo (state already
  holds the new values at that point). Cold-start then re-logs in with a
  verifier derived from the new key. Falls back to clearing if the
  re-wrap throws, so a stale old-key blob is never left behind.
- PIN blob still cleared (wrapped by PBKDF2(pin) — can't re-wrap without
  the PIN). A setTimeout(0) separates the quickunlock/store and pin/clear
  navigations so the back-to-back window.location.href assignments don't
  coalesce and drop the re-wrap.
- Fixed a `failed` counter declaration accidentally dropped from the
  attachment re-encryption loop while adding progress (ReferenceError at
  runtime; node --check wouldn't catch it).
- CLAUDE.md updated for the re-wrap vs clear distinction.

Rebuild: BuildAssets + F9 (JS only this commit; F9 to re-embed).

r-zakarya 22bec64348 fix: chunk auto-backup writes + spinner on manual "Backup now"
Bridge.writeFile had the same URL-length trap saveFile did: a large
auto-backup base64'd into a single cmd://file/write URL blew past
WebView2's ~2MB navigation cap, so backups of big vaults failed
silently (or blanked the page) — for BOTH the manual "Backup now"
button and the silent scheduled run.

- writeFile now streams payloads over ~1MB in chunks (reusing the same
  file/chunk transport as saveFile), committed via a new
  file/write-commit. Delphi shares the decode+write logic through a new
  WriteDecodedFile helper and the existing FFileSaveChunks buffer.
- runAutoBackupNow(silent): the manual run shows the busy overlay
  ("Reading vault… N/total" → "Encrypting backup…" → "Writing file… N%")
  since a 20MB backup takes ~30s; the scheduled on-unlock run passes
  silent=true (no overlay, but still chunked so it no longer fails on
  large vaults).
- Fixed the "Backup now" click handler passing the click Event as the
  silent arg (truthy → would have suppressed the spinner and swallowed
  errors); wrapped in () => runAutoBackupNow().
- Pre-sync backup benefits from the chunked writeFile automatically.

Rebuild: BuildAssets + F9 (UMainForm.pas changed).

r-zakarya c5fe26ce94 feat: chunked file save + export progress spinner + password-reveal + avatar size
Large file save (fixes black screen on big attachment download / export)
- Bridge.saveFile streams anything over ~1MB base64 in chunks through the
  cmd:// channel instead of stuffing the whole payload in one URL — a
  multi-MB base64 URL blew past WebView2's ~2MB navigation cap and blanked
  the document (black screen). Small payloads keep the single-shot path.
- Chunks are sent sequentially (each acked via Bridge.onFileChunkAck
  before the next) so repeated location.href assignments don't coalesce.
- Delphi accumulates chunks per reqId in a TStringBuilder
  (FFileSaveChunks), commits on file/save-commit, and shares the
  decode+dialog+write logic with the single-shot path via SaveDecodedFile.
- Chunk size 1MB → far fewer round-trips (a 20MB export dropped from ~67
  to ~27 hops).

Busy overlay + progress
- Global spinner overlay (showBusy/updateBusy/hideBusy). doExport shows it
  immediately on click — BEFORE the entry-decrypt + attachment-fetch loop
  that is the real cost — with a 0ms yield so it paints before the thread
  blocks (was appearing 3-5s late). Phases: "Reading vault… N/total" →
  "Encrypting export…" → "Preparing file… N%" (real chunk progress).
  Attachment download shows the same for files > 512KB.
- Spinner ring used an undefined --bg-elev-3 (invalid border → invisible);
  switched to --border. Fixed a second stale --bg-elev-3 use on the
  settings-search clear button hover.

Password reveal
- promptDialog gets an eye toggle in password mode, so every encrypted
  prompt (export, import, backup password, recovery code, sync password)
  can show/hide the typed value.

Avatar
- Top-right chip avatar enlarged 22px → 30px with the chip padding
  rebalanced.

Rebuild: BuildAssets + F9 (UMainForm.pas changed for the chunk handlers).

r-zakarya 3f8ecde571 feat(security): decouple the login verifier from the AES vault key
The zero-knowledge verifier sent to /login used to be the raw PBKDF2
output in hex — i.e. the exact bytes of the AES key that encrypts every
entry. Intercepting a /login body (loopback, but still) handed over the
vault key. This introduces a decoupled scheme where the transmitted
verifier is a one-way function of the key.

New auth-hash scheme
- users.hash_algo 'pbkdf2-sha256-v2': the client sends
  verifier = SHA256(keyHex + "pmserver/auth-verifier/v2") instead of
  keyHex. Stored form is still SHA256(verifier) (identical server wrap
  to 'pbkdf2-sha256'), so only the algo LABEL differs — it tells the
  client which verifier formula to use. Verification needs no new server
  branch (VerifierToStoredHash already SHA256-wraps any non-legacy
  verifier).
- The AES key (cryptoKey) stays hex(PBKDF2) for EVERY algo, so entries
  remain decryptable and switching schemes never re-encrypts data.

Adoption: new-registration + master-pw-change only
- Register and change-master-password write v2. Existing accounts keep
  their algo until they rotate — the login/reauth migration signal now
  fires only for LEGACY 'pbkdf2' (was: anything != CURRENT), so
  sha256/v2 accounts are never force-migrated (which would have
  downgraded v2 → sha256 via migrate-kdf).

Client (js/app.js): algo-aware everywhere
- verifierFromKeyHex(keyHex, algo) central helper; deriveKeyAndVerifier
  / computeVerifier take an algo arg. state.hashAlgo caches the account
  scheme, set from /login/challenge, register, change-master, the
  quick-unlock / PIN cold-start blobs, and the /recovery-key/redeem
  response. All ~12 verifier sites updated (login, register, reauth ×4,
  change-master current+new, migrate-kdf, quick-unlock + PIN cold-start,
  recovery-mode current verifier).

Safety invariant: unknown/empty hashAlgo → key hex → byte-identical to
the old behaviour, so every pre-decoupling account (and every existing
quick-unlock / PIN blob without the new field) keeps working unchanged.
Verified: existing account + pre-change quick-unlock still unlocks; a
master-pw change now writes 'pbkdf2-sha256-v2' in vault.db.

Server: recovery redeem returns hashAlgo; register + change-master store
the decoupled algo; login + reauth migration signal narrowed to legacy.

Also: BuildAssets.ps1 pipes $null into node --check so the JS syntax
gate can't block on stdin in the Delphi pre-build environment.

Addresses CODE_AUDIT.md section 1.1.

r-zakarya 3076fec710 feat: quick-search fill modes + editable custom-field combobox + JS build gate
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.

r-zakarya 7440d07793 feat: profile avatar + tombstone-restore fix + WebView2 nav race + sync summary
Profile picture / avatar
- users.avatar_b64 column (nullable, cosmetic, not encrypted) + GET/POST
  /avatar endpoints mirroring the settings handler pattern.
- Top-right chip + Settings→Account show a round avatar: custom picture
  if set, otherwise the username's initial on a deterministic
  hash-picked colour (stable across renders).
- Upload downscales + center-crops to a 128px JPEG via FileReader →
  data: URI (NOT blob:, which the CSP's `img-src 'self' data:` blocks)
  before POSTing. Remove button clears it.
- Carried in the encrypted JSON export; restored on import only when the
  current account has no picture (never clobbers a local one).

Tombstone restore-then-sync fix
- POST /entries and POST /entries/bulk-import now DELETE any tombstone
  matching an inserted uuid (same transaction) so a restored backup
  isn't re-killed on the next sync by its own stale tombstone.
- applyRemoteSnapshot arbitrates remote tombstones by timestamp: a
  tombstone is skipped when the local entry with that uuid is newer than
  deleted_at (resurrection wins). Ties / unparseable timestamps favour
  KEEP. loadEntries() up front so updated_at reflects the live rows.

WebView2 navigation race
- Black-window-on-cold-start fix: the 1.5s nav timer no longer consumes
  FPendingURL when WebView2 isn't initialised yet (it re-arms, bounded
  to ~10 retries). FBrowserInitialized flag set in OnInitialized; after
  the retry budget we Navigate best-effort rather than loop forever.

Sync UX
- Bidirectional toast: "pulled X new · Y updated · Z deleted · pushed N
  entries" so a 0/0/0 pull still shows the vault was uploaded.
- FolderPOST/PUT: pre-declare ftString on color/icon params (fixes the
  earlier [SQLite]-335 on NULL bind, already in play for CSV import).

Docs
- CLAUDE.md sync section documents tombstone purge-on-insert +
  resurrection arbitration.

r-zakarya 0a3372c151 feat: sync guards + import restore mode + inline progress + uncategorised polish
Sync engine
- Cross-account guard: refuse to merge a remote snapshot whose
  username differs from the currently-signed-in one (confirm dialog,
  Cancel by default) so a shared WebDAV URL / same sync password
  between accounts stops silently mixing vaults.
- Local tombstones veto: skip any remote entry whose uuid is already
  in the local entry_tombstones table — otherwise a perm-delete on
  this device was getting undone on the next pull.
- "deleted" counter fixed: report only tombstones that actually
  removed a live local entry this round, not the accumulated history
  the toast used to inflate ("73 deleted" for 48 real deletes).
- Push failure surfaces syncStatus reset + toast so state doesn't
  get stuck on a stale phase label.

Sync progress feedback
- Inline #syncStatus label next to the Sync button reports each
  phase: Local backup… → Pulling… → Merging… → Preparing… N/total
  (per-entry counter during the slow buildSyncSnapshot decrypt loop)
  → Encrypting… → Pushing…, then clears.
- Sync now / Test connection buttons are disabled while any run is
  in flight so double-clicks can't kick off a concurrent sync.

Import (JSON only — CSV out of scope)
- Uuid-aware dedup: split parsed rows into fresh (new uuid) vs
  overlaps (uuid already present locally).
- Overlaps prompt: confirm dialog offers Overwrite (restore/roll
  back) or Skip. Overwrite PUTs the file's payload over each match;
  Skip drops them and only imports fresh. Prevents the "re-import
  doubles everything" regression while still allowing restore.
- Bulk-import call is skipped entirely when there's nothing fresh to
  send (avoids a POST with an empty entries array).
- Template notes with empty body but populated custom_fields
  (credit-card, ssh-key, etc.) no longer skipped as "note body
  required" — kept as long as at least one custom field has a value.

Sidebar / uncategorised view
- "(no folder)" pseudo-entry stays visible whenever the vault has
  any real folder, so it always works as a drag target for
  uncategorising — and doesn't vanish mid-action when the user is
  currently viewing it.
- Header title reads "(no folder)" for state.view === 'folder:All'
  instead of the ambiguous "All".
- Dedicated empty-state copy for the uncategorised view.

Rebuild assets required.

r-zakarya fbfc24a4d5 feat: sticky slideover Save + uncategorised-view polish + regression plan
- Slideover Save action row is now sticky at the bottom of the scrolling
  body (background + top border) so it stays reachable on entries with
  many custom fields or attachments — was previously buried below the
  fold.
- Uncategorised view (state.view = 'folder:All'):
  - Header title reads "(no folder)" instead of the ambiguous "All".
  - Sidebar pseudo-entry stays visible whenever the vault has at least
    one real folder, so it can be used as a drag drop-target to move
    entries out of a folder even when its own count is 0.
  - Empty state gets its own copy ("No uncategorised entries" + hint
    to drop entries here to uncategorise) instead of the generic
    "Folder is empty".
- TEST_REGRESSION.md checked in — 16-section list scoped to what the
  recent Esc / drag / sync / import work touched, so post-commit
  regressions can be walked through methodically instead of poking
  the app ad-hoc.

r-zakarya 4cb45ec63a fix: Esc priority across slideover / settings / modal handlers
Pressing Esc after editing a card silently failed: requestCloseSlideOver
opened the discard-confirm modal, then the global Esc-fallback handler
fired on the same keystroke and either closed the just-opened modal
(when Esc came on a clean slideover via the modal path) or, when
Settings was layered on top of a dirty slideover, opened the discard
prompt in the background while Settings closed.

Both panel-level Esc handlers now run in capture phase and
stopPropagation:
- Slideover handler stops only when it actually acts (slideover open,
  no modal up, Settings not on top) so a single Esc opens the discard
  confirm without the global fallback racing to close it.
- Settings handler stops when Settings is the active panel so the
  global fallback's requestCloseSlideOver branch can't fire underneath
  and pop a discard confirm on the slideover the user left dirty.

Priority order is now: open modal > Settings > slideover. First Esc on
"card dirty + Settings open" closes Settings; second Esc shows the
discard confirm. Clean slideover + Esc still closes directly.

r-zakarya bd14831449 feat: Bitwarden import bundle + settings search + quick-search hotkey + UX fixes
- Bitwarden CSV import: folders auto-created server-side; notes column on
  login rows surfaces as a "Notes" custom field instead of polluting tags;
  type=card / type=identity rows now mapped to kind=note with the
  credit-card / identity template + card_* / identity_* columns
  pulled into custom_fields; `fields` column parsed (Bitwarden's
  "label: value\nlabel: value" lines + our own JSON shape).
- Settings panel search: live filter at top of the panel, matches each
  .setting-row individually, hides whole section when no row matches,
  shows a "No matches" banner. Esc clears query (without closing
  Settings); Esc with empty query closes the panel.
- Quick-search hotkey customizable: SetQuickSearchHotkey added to
  PM.Bridge; cmd://autofill/hotkeys extended with qs_mods/qs_vk
  (independent of the autofill enabled flag — quick-search stays
  armed even when autofill is off); state.quickSearchHotkey synced
  via settings_json; new "Quick search picker" row in Settings.
- FireDAC SQLite folder POST/PUT: pre-declare ftString on color/icon
  params so .Clear (NULL) doesn't trip "[FireDAC][Phys][SQLite]-335
  type unknown" at Prepare — was crashing the CSV-import folder
  auto-creation path.
- Edge form-data autocomplete suppressed on slideover inputs (title,
  site, username, password, TOTP, note body, custom fields):
  autocomplete=off (new-password on secrets) + spellcheck=false. Fixes
  the "Informations enregistrées" dropdown popping over data after a
  field was edited.
- closeSlideOver blurs any focused descendant before removing .is-open
  so an invisible focused field can't react to arrow-down / backspace
  after dismissal.
- Slideover Esc handler upgraded to capture phase so it fires before
  the input's own keydown or browser-level Esc swallow on the active
  autocomplete popup.
- Settings panel Esc closes the panel when search input is empty;
  search keeps the keystroke when it has a query to clear.
- Discard-fantome on note open: customFields working copy and
  originalCustomJson now share the SAME normalized array — comparing
  raw plainCustom against the .map()'d working copy made notes look
  dirty on open.
- Delete / Backspace global shortcut: batch-trash on normal views,
  batch perm-delete on trash view, gated on selection + no input
  focused + no modal up.
- Toggle thumb vertical centering via top:50% + translateY(-50%);
  state checked uses translate(16px, -50%) to keep the centring.
- Batch bar disappears after per-card restore/perm-delete/trash:
  state.checked.delete(id) before render for the relevant flows;
  state.checked.clear() before render in emptyTrash and the new
  moveEntriesToFolder helper.

r-zakarya 6869b7c692 feat: WebDAV sync + batch DnD + clean shutdown + center-modal UX bundle
- Sync (WebDAV, auto-merge): UUID + tombstones foundations (server +
  JS), THTTPClient bridge cmds (get/put/test), runSyncNow engine with
  pull/merge/push flow, Settings UI, pre-sync backup option. Test
  connection now treats 404 as OK (snapshot not yet created) and 401/
  403 as auth failure with dedicated toast.
- Batch drag-drop: cards + table rows carry checked-set ids (CSV) when
  dragged from an active selection; folder + trash drop handlers parse
  and apply in batch via new moveEntriesToFolder helper that preserves
  TOTP / custom_fields / kind in the full PUT payload.
- Clean shutdown: WM_QUERYENDSESSION / WM_ENDSESSION captured in the
  bridge message-only window; FormCloseQuery bypasses the tray-minimize
  intercept on system shutdown / restart / logoff so FireDAC closes the
  SQLite WAL cleanly instead of leaving -shm / -wal residue after a
  force-kill.
- Center-mode modal: blur+dim backdrop via body::before pseudo-element
  in editor-position=center, swallows clicks below the panel so the
  existing outside-click handlers reliably dismiss the slideover /
  settings panel.
- Batch bar state fixes: state.checked cleared before render in
  moveEntriesToFolder, emptyTrash, and per-card restoreEntry /
  permanentDelete / deleteEntry so the action bar disappears once the
  selection is fully processed.
- Save-then-discard duplicate fix: soState reset to null before
  openSlideOver re-opens the freshly saved entry, otherwise the dirty
  check fired on the soState.id=null → newId switch and a Cancel left
  the form in new-entry mode (second Save → POST duplicate).
- TEST_SYNC.md: end-to-end checklist for validating the WebDAV sync
  with 2 real instances.

r-zakarya b00da43ab0 feat: PIN unlock + table column picker + edit-position chooser + UX
- PIN unlock: device-local 4-12 digit shortcut, DPAPI-wrapped vault
  key. Three modes (state.unlockMode): pw / pin / pw+pin. PIN
  derives a wrap key via PBKDF2(pin, salt, 100k) and unwraps the
  stored vault key (mirrors the Quick Unlock blob shape).
  Anti-brute-force: 5 wrong attempts wipes the blob. Setup gated by
  master-pw reauth so an unattended unlocked laptop can't be
  backdoored. Master pw rotation clears the PIN blob (key drift).
  loadServerSettings post-sync demotes pin/both -> pw when the local
  blob is missing, so a wiped device re-syncs the correct mode up.
  New unit PM.PinUnlock.pas + cmd://pin/{store,get,clear,status}.
- Table column picker: ⚙ in topbar (table view only), checkbox menu
  for Site/Username/Folder/Updated. Site also drives showSiteOnCards
  so the existing "Show site / URL" toggle in Settings stays in
  sync. NAME column auto-widths (180px min, content max, +32px
  right padding) so column hugs the next one without truncating.
- Editor position chooser (Appearance setting): Slide-over right /
  left / Centered modal. Scoped to #slideover + #settingsPanel so
  the click-outside / pointer-events logic doesn't accidentally
  trap the modal-style empty viewport.
- Confirm before discarding unsaved edits: state.confirmOnUnsaved
  setting (default ON), prompts on X / Esc / click-outside / switch-
  to-other-entry. Also gates Lock vault / Sign out actions when the
  editor is dirty; auto-lock and system-lock paths bypass to avoid
  blocking on an unattended machine.
- Open-in-browser button added to the actions cell of the table
  view (was card-only).
- Entry templates pass folder customization + template id through
  duplicate / export / import / auto-backup roundtrips.
- Folder color + icon now persisted across export/import: payload.
  folders carries name/color/icon; import creates missing folders
  additively (existing local customisation kept).
- Bulk move-to-folder, batch add-tag, single add-tag now re-ship
  the full entry payload so partial PUTs don't silently wipe
  TOTP / custom_fields / kind / template.
- FireDAC: switched ftString -> ftMemo for icon_b64 / custom_fields
  / TOTP / template params and replaced .AsString with .Value so a
  large (~200 KB) DeepSeek favicon no longer gets truncated at the
  default ANSI 4000-char cap.
- Unicode filenames: attachment INSERT now uses ftWideString +
  .AsWideString so non-ANSI filenames round-trip instead of being
  mangled to "?".
- HandleSetEntryIcon cap raised 256 KB -> 512 KB chars to accept
  base64 data URIs produced by max-raw favicon fetches.
- promptDialog + askReauth support inline `error` line + retry-
  with-count loops on doExport reauth and auto-backup password
  setup (5 attempts cap before bailing).
- Recently used moved from Tools to Vault section in the sidebar.
- Auth screen passkey button hidden (Delphi backend stubs WebAuthn).
- Sensitive cmd://favicon/refresh-style buttons in Settings now
  stopPropagation so the document-level "close panel" handler
  doesn't dismiss Settings mid-async during DOM reparenting.
- TEST_PLAN.md: +PIN unlock section.

r-zakarya e23a78dda7 feat: entry templates + tag autocomplete + slideover push + robustness bundle
- Entry templates: new vault_entries.template column drives a typed
  sub-kind ('credit-card', 'ssh-key', 'server', 'recovery-codes'). Card
  + table label off the template, badge reads "credit card" instead of
  "note". Templates seed kind=note (no site/password required), use
  custom_fields with optional dropdown options (brand, month/year,
  protocol). Round-tripped across export/import/duplicate/master-pw
  rotation, preserved by partial PUTs via a HasTemplate flag.
- Custom fields: support per-field `options[]` rendering as <select>
  (card brand, expiry MM/YYYY, SSH/server protocol).
- Tags: existing-tag autocomplete dropdown under the chip input,
  filtered against what's already selected.
- Search history: per-query X for individual delete + 1s debounced
  commit (no Enter required).
- Slideover: clicking outside closes again (drag-selection respected
  via mousedown origin tracker), Esc closes, X closes. App shell is
  pushed left by 420px when the panel is open so the table / pagination
  / sort / search stay visible and interactive.
- Export/import: JSON now round-trips custom_fields, attachments
  (decrypted to base64, re-encrypted under current key on restore),
  icon_b64, and template. CSV warning lists what's not included.
- Auto-backup: same payload shape as user-driven export.
- Notes: import (JSON + CSV) accepts kind=note with empty site,
  preserves title/template/custom_fields. CSV parser detects kind/
  template columns.
- Bulk-import response returns `ids[]` parallel to input so the
  client can map back to new entry IDs (drives attachment restore).
- Move-to-folder bugs fixed: moveEntryToFolder, batchMoveToFolder,
  addTag, batchAddTag were all silently wiping TOTP / custom_fields
  / kind / template via partial PUT. Now re-ship full payload.
- Master-pw rotation: server mints a fresh session token + csrf so
  the very next request after rotation no longer ESessionRejects.
  Client adopts the new pair. Attachments are re-encrypted client-side
  during rotation (GET old → decrypt with old key → encrypt with new
  → PUT). New endpoints: GET /attachments/all, PUT /attachments/:id.
- Duplicate: carries icon_b64 + template + attachments to the copy.
- HandleCreateEntry: accepts icon_b64.
- FireDAC param fix: all blob/icon/custom_fields params use ftMemo +
  .Value assignment so SQLite TEXT no longer truncates to 4000 chars
  (deepseek's 200+ KB favicon was being wiped on lock/unlock).
- HandleSetEntryIcon cap: 262144 → 524288 chars (base64 of a 256 KB
  raw fetch overflows the old cap, fails silently in saveEntryIcon).
- Native save dialog: surfaces server errors instead of swallowing.
- Modals: reauth (export) + backup-password prompt support inline
  error display, retry up to 5 attempts, then hard-stop.
- Keyboard cursor (j/k): bootstraps to current page, auto-paginates
  when the cursor crosses a page boundary, Enter opens slideover.
- Slideover focuses Title on edit-open so j/k → Enter → type Just
  Works.
- TOTP tool: Esc closes the modal.
- App version + launch mode (auto/manual): exposed via bridge,
  surfaced in Settings → Account. Autostart launches suppress the
  first-time tray balloon.
- Passkey button hidden (Delphi backend stubs WebAuthn at 501).
- TEST_PLAN.md captured for regression coverage.

Zaki fa7ea191be feat: native save + auto-backup + folder customization + attachments + UX bundle
- File: native Save As dialog via Bridge.saveFile (replaces WebView2
  browser download popup) for encrypted JSON + CSV exports.
- Auto-backup: silent periodic encrypted JSON to a chosen folder,
  user-set interval + retention, separate DPAPI-stored password, runs
  5s after unlock if due. New file/* bridge cmds (folder/pick,
  file/write, file/listMatch, file/delete).
- Folders: per-folder color + icon (8-swatch palette, 8 icon presets),
  drag-reorder via HTML5 DnD with insert-line indicators, edit pencil
  on hover. New POST /folders/reorder + PUT /folders/{name}. Folder
  chip on cards inherits custom icon + color.
- Recently used: vault_entries.accessed_at + POST /entries/{id}/touch
  (debounced 2s), sidebar Tools entry showing top-10 by accessed_at.
- Encrypted attachments: per-entry file storage (5MB cap), AES-GCM
  with vault key, native Save As download, paperclip upload in
  slideover. New entry_attachments table + PM.Handler.Attachments.
- Password expiry: vault_entries.password_changed_at (conditional bump
  via SQL CASE only when ciphertext differs), passwordExpiryDays
  setting, "Aged" badge on cards + matching Filters chip.
- Recovery: Print button on generated code modal (A4 printable sheet
  via @media print, code in 32px monospace + instructions).
- Audit log viewer (sidebar Tools, GET /audit with pagination cursor).
- Plaintext CSV export + Filters dropdown with 9 predicates.

Zaki 63fac5b3b7 feat: secure notes + password history + custom fields + quick-win bundle
Big feature trio
- Secure notes (kind='login'|'note') reusing the encrypted_password+iv
  pipeline for the body. New sidebar entry, slideover variant (title +
  multiline body), distinct card / table-view rendering, badge in name
  column, copy-content button replacing the password copy on note rows.
- Password history: entries_password_history table keeps up to 20 prior
  ciphertexts per entry. HandleUpdateEntry pushes the pre-update
  encrypted_password into history ONLY when it actually differs from
  the incoming one (JS reuses originalEncrypted bit-for-bit when the
  plaintext is unchanged — avoids spamming history on title/folder edits).
  GET /entries/{id}/history endpoint. Slideover modal lists versions
  with mask/reveal/copy/revert. Master-pw rotation wipes history (old
  ciphertext can't be decrypted with the new key).
- Custom fields: per-entry encrypted JSON array of {label, value,
  is_secret}. Same crypto pipeline as the password. Slideover row UI
  with label/value inputs, secret toggle (eye), copy, delete. Re-
  encryption flows through bulk-import, change-master-password, and
  duplicate.

Quick wins
- Cheatsheet overlay (press '?' or topbar button or Ctrl+K). Lists all
  hotkeys + global / tray / card actions. SVG icons inline so the
  cheatsheet matches the actual app glyphs (no emoji mismatch).
- Open URL button on entry cards: ShellExecute via cmd://app/open-url,
  http(s) only, validates entry.site looks like a real hostname.
- Trash auto-purge: setting "Empty trash after N days" (never/7/30/90).
  DELETE /entries/trash/old?days=N called at every unlock.

Favicon strategy
- Subdomains (chat.deepseek.com, app.X.com…) now try the SLD first
  (deepseek.com.ico) before the full host. DDG often returns a generic
  placeholder for subdomains that passes the byte threshold; the SLD-first
  switch surfaces the real brand icon.
- Cap bumped 64 KB → 256 KB on all three sides (Delphi fetch, server
  endpoint, JS upload). DDG sometimes serves the full-res asset.

UX polish
- Click-outside-slideover: stopPropagation everywhere it bites. Custom
  fields buttons (add / delete / secret toggle / copy / eye) all stop
  the click bubble so the document-level "close on outside click" handler
  doesn't fire when rerender() detaches the target from the DOM.
- Native search-cancel button restyled: cyan accent X via mask-image,
  cursor: pointer, breathing room before the Ctrl+K kbd chip.
- Password history modal: scrollable body, multiline wrapped passwords,
  hover border highlight.
- Cheatsheet panel widened (560 → 720 px) so the descriptions no longer
  ellipsis-clip.
- "+ New" topbar splits into a small dropdown: New login / New note.
- Notes show a "note" badge in table-view name column, italic
  "Encrypted note" placeholder in the username column.

Internals
- duplicateEntry copies kind + custom_fields too (one-line forgotten
  earlier).
- entries_password_history dropped on master-pw rotation — the old
  ciphertexts are unrecoverable with the new key.
- bulk-import re-encryption path includes custom_fields.

CLAUDE.md
- "Entry payload — call sites à toucher ensemble" lists the 6 spots
  to update when adding a new (en)crypted field. Notes the historical
  miss of kind in duplicateEntry and custom_fields in the rotation +
  duplicate.

Repo hygiene
- .gitattributes forces CRLF on Delphi sources (RAD Studio refuses LF).
  text=auto for web frontend / docs, binary for .res / .exe / images.

Zaki 39406d712e feat: Ctrl+Shift+Q quick-search-fill + Edge browser directive
Ctrl+Shift+Q quick-search + autofill
- New global hotkey: capture the foreground HWND, restore the window
  if hidden, pop the quick-search modal in "fill mode". On pick, the
  password is SendInput'd into the saved HWND — no clipboard touch.
- hide_after flag added to cmd://autofill/execute: when set (tray-mode
  hotkey), Delphi MinimizeToTray's *after* SendInput completes. Hiding
  before SendInput would trip Win10/11 anti-focus-stealing rules and
  block focus handoff to the target.
- Quick-search modal hint text adapts to fill vs copy mode.
- Esc / close in fill mode sends cmd://autofill/cancel so a stale
  HWND doesn't get reused by an unrelated Ctrl+Shift+L later.

Compile-time browser engine switch
- {.$DEFINE USE_EDGE_BROWSER} in UMainForm.pas selects between
  TTMSFNCWebBrowser (default, cross-platform abstraction) and
  TTMSFNCEdgeWebBrowser (Windows-only WebView2 wrapper). Both
  inherit from TTMSFNCCustomWebBrowser so the bridge cmd:// glue is
  unchanged; the field type is a conditional alias TWebBrowserClass.
- WebBrowser is created dynamically in FormCreate so neither variant
  needs a second .fmx. Events are wired BEFORE Parent assignment so
  OnInitialized doesn't race the WebView2 async init on fast/pre-warmed
  Edge installs (was silently missing the disable-context-menu /
  disable-accelerator-keys calls).
- Native context menu disabled by assigning an empty PopupMenu1 (works
  for both backends, unlike OnGetContextMenu which is publish-gated
  via {$IFNDEF FNCLIB} on TTMSFNCWebBrowser).

Zaki f047fba9a3 feat: tray quick-search + privacy hardening + race fixes
Quick search from tray
- New "Quick search…" entry in the tray context menu (between Open
  and Lock vault).
- Compact modal with live-filtered top-8 entries, arrow keys / Enter
  to copy the password (Shift+Enter copies the username instead),
  Esc to dismiss. Each row shows the favicon when cached.
- Locked vault → focus the master password input instead of opening
  the modal (same pattern as the locked-autofill-hotkey path).
- Window-state restore: Delphi remembers whether the window was
  hidden before the menu was opened and tells JS via the
  Bridge.openQuickSearch(wasHidden) arg. After the copy (or cancel)
  we hide back to the tray so the previously-foreground app comes
  back and Ctrl+V drops the password in.

Tray notifications toggle
- New Settings → Security "Show tray notifications" toggle. Gates
  Shell_NotifyIcon NIF_INFO balloons (currently only the "still
  running in the tray" first-time popup). Default ON, synced via
  settings_json so it follows the user across devices.
- PM.Bridge.ShowNotifications exposed as a public property; JS
  pushes the value on every settings sync.

Privacy: WebView2 phone-home killed
- WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS set in the unit
  initialization section (before the TMS WebBrowser instantiates
  its CoreWebView2Environment). Disables: background networking,
  sync, component updates, breakpad/crashpad, domain reliability,
  client-side phishing detection, experiments, UMA upload,
  MediaRouter, OptimizationHints, SafeBrowsing enhanced, autofill
  server, privacy sandbox APIs. Verified via Resource Monitor: only
  127.0.0.1 connections remain (plus DDG when favicons are on).

Fixes
- Blank-window-on-launch race: the 1.5 s navigation timer assumes
  WebView2 finishes init in time, but on slow machines Edge
  Chromium needs 2-3 s and the Navigate() call is silently
  dropped. WebBrowserInitialized now also navigates if a URL is
  still pending — first to run wins.

Zaki 2ef636ce30 feat: unified entry slideover + custom icons + UX fixes
Unified create/edit slideover
- openSlideOver(id) now accepts null for new entries. Same UI
  (icon, name, site, user, password, TOTP, folder, tags) for both
  create and edit. Drops the separate entry modal — no more "save
  first, then add TOTP" two-step.
- "+ New" button, Ctrl+K → New entry, and Ctrl+Shift+A all route
  through the slideover. Ctrl+Shift+A pre-fills the title with the
  foreground window's name.
- Save button visible from the start in new mode (no dirty wait).
- Title shows mode unambiguously: cyan "+ New entry" vs
  "Edit · <name>".

Custom icon upload (soIconField)
- 56×56 preview at the top of every slideover + Upload icon /
  Remove buttons. Same POST /entries/{id}/icon endpoint as the
  auto-fetch path. Validates type / size (64 KB cap matching server).
- Solves the case where DDG doesn't index a domain (self-hosted
  apps, private sites): the user pastes any image and it sticks.

Favicon: privacy-first, DDG only
- Removed the direct-fetch fallback steps (3-5). Privacy stance:
  zero DNS leak outside icons.duckduckgo.com. Domains DDG doesn't
  cover stay icon-less until the user uploads a custom one.
- PM.Favicon.FetchFaviconDataUri takes an optional TFaviconLog
  callback so UMainForm can stream per-step trace into LogLine for
  diagnostics.

Fixes
- Slideover z-index 30 → 50. The topbar's backdrop-filter creates a
  stacking context at z-index 40 which was clipping the slideover
  header (title + close button hidden behind topbar).
- RestoreFromTray no longer un-maximises a maximised window when
  called outside a tray-restore context (Ctrl+Shift+A, Ctrl+Shift+L
  picker, app/focus cmd). SW_RESTORE on a maximised window reverts
  to normal — now we only SW_RESTORE if IsIconic.
- "Show all"/"Show less" per-category state survives renderGrid
  re-renders (healthExpanded map).
- "+ New" and dashboard "Fix" buttons stopPropagation so the
  document-level click-outside handler doesn't close the slideover
  they just opened.
- soDirtyCheck keeps Save visible while in new mode regardless of
  diff.
- openSlideover → openSlideOver typo fix across all call sites.

Zaki ad5fb21a18 feat: website favicons + vault health dashboard
Favicons
- PM.Favicon (new): THTTPClient/WinHTTP proxy to icons.duckduckgo.com.
  Native Windows TLS — no OpenSSL DLLs to ship (Indy would fail
  silently without them). 5 s timeout, max 3 redirects, 64 KB cap,
  magic-byte MIME sniffing.
- DB: vault_entries.icon_b64 TEXT (idempotent migration).
- Endpoints: POST /entries/{id}/icon stores a cached data URI without
  forcing a full PUT (which would re-encrypt the password). DELETE
  /entries/icons/all purges the cache.
- Bridge cmd://favicon/fetch?host=X&reqId=Y runs in an anonymous thread
  so the up-to-5 s HTTP GET doesn't block the main thread; result
  shipped back via Bridge.onFaviconResult(reqId, host, dataUri).
- Hostname validated on both sides (JS faviconHost + Delphi
  NormalizeHost) so brand labels like "Gitea" never leak upstream.
- Settings: opt-in "Fetch website icons" toggle (synced), three explicit
  actions (Fetch missing / Re-fetch all / Clear cache) that bypass the
  toggle — manual user actions always work.
- Entry card avatar shows <img> when cached, falls back to initials.
  onerror handler recovers silently from a corrupt data URI.

Vault health
- New sidebar Tools → "Vault health" view. Four category cards:
  Weak (strength < 50), Reused (same plaintext on ≥ 2 entries), Old
  (updated_at > 365d), Pwned (HIBP cache).
- Score 0-100 with colour band (Good/Fair/At risk/Critical).
- One-shot computation cached per session (healthCache), invalidated
  on lockVault, entry save, and the explicit "Recompute" button.
- "Fix" button on each item opens the slideover for the affected
  entry, unmasks the password, focuses it, and pulses the dice button
  — full context preserved, user decides how to fix.
- Click handler stopPropagation prevents the document-level
  "click outside slideover" listener from closing the panel that
  we just opened in the same click event.

Fixes
- openSlideover typo (lowercase O) → openSlideOver across all call
  sites. Was silently breaking the Authenticator card click and the
  Vault health Fix button.
- W1050 WideChar warning in PM.Favicon — replaced set-membership
  with explicit Ord-style range comparisons.

Zaki 33e4b4b614 feat(autostart): "Start with Windows" toggle
- PM.AutoStart wraps HKCU\Software\Microsoft\Windows\CurrentVersion\Run.
  Value "PMServer" = "<exe>" -tray. Per-user, no admin required, shows
  up in Task Manager → Startup so the user can override from there.

- UMainForm honours the -tray CLI flag (set by the registry entry):
  after the server starts, MinimizeToTray via TThread.ForceQueue so the
  app comes up directly in the tray with no visible window flash.

- Bridge cmd://autostart/{get,set} + Bridge.getAutoStart() /
  setAutoStart() / onAutoStartStatus(). Settings exposes a toggle in
  the Security section, visible only when Bridge.active (the PHP
  frontend can't touch the registry).

- Toggle reads "on" only when the registered command matches the
  current exe path, so a stale entry from a moved exe lets the user
  re-enable to refresh.

Zaki 40b3154a34 feat: MFA tools, single-instance, tray polish, prefs persistence
Session highlights:

- feat(prefs): DPAPI-backed key/value store (PM.UserPrefs) — fixes
  rememberedUsername being lost across reboots due to the random
  ephemeral HTTP port changing the localStorage origin every launch.
  Bridge cmd://prefs/{get,set} round-trips through Delphi.

- feat(tray): icon visible from startup (NIM_ADD at constructor, not
  at first minimize). Tray context menu themed via uxtheme!135
  SetPreferredAppMode so it follows the app's dark/light setting.

- feat(single-instance): named mutex + RegisterWindowMessage broadcast.
  Second launch posts WM_PMSHOW to HWND_BROADCAST and exits; the
  running bridge restores the window from tray. Mutex lives in Local\
  namespace so distinct Windows users can still each run one.

- feat(mfa): Authenticator sidebar view (live TOTP codes for every
  entry with a secret) + standalone TOTP generator modal (paste
  base32 / otpauth:// URI, or generate a random 20-byte secret).

- feat(sidebar): Folders / Tags / Tools sections collapsible with
  chevron toggle. Badge counts stay visible when collapsed. State
  persisted in settings_json (synced across devices).

- feat(autofill): hotkey when vault is locked now restores the app
  and focuses the master password input instead of no-op'ing
  silently. Cleaner UX for the common "I hit Ctrl+Shift+L but the
  vault was locked" path.

- feat(quick-unlock): when enabled, skip lockVault on Windows lock /
  sleep. Rationale: the DPAPI blob already gates access via the
  Windows account, so re-locking on top of the OS lock is redundant.
  Idle auto-lock still fires (separate opt-in).

- fix(quick-unlock): re-sync state.quickUnlockEnabled from DPAPI
  source-of-truth at boot, instead of trusting (now-volatile)
  localStorage.

- docs: CLAUDE.md updated with all new modules, bridge commands,
  and the port-ephemeral pitfall.

Zaki 664db65437 fix(db): declare TOTP param DataType so .Clear works on first row
FireDAC raises EFDException -335 "data type unknown" when .Clear is
called on a TFDParam before any typed value has been assigned. Hit
in PM.Handler.Auth.HandleChangeMasterPassword when the first entry
in the migration loop had no TOTP secret — already fixed inline.

Same latent bug existed in every other handler that touches the
optional totp_secret / totp_iv columns:
 - HandleCreateEntry      (Entries.pas)
 - HandleUpdateEntry      (Entries.pas)
 - HandleBulkImport       (Entries.pas)

All three now declare:
  LQ.ParamByName('ts').DataType  := ftString;
  LQ.ParamByName('tiv').DataType := ftString;
right after setting SQL.Text, so the very first .Clear (when an
entry has no TOTP) doesn't fail with "data type unknown" on the
SQLite param binding path.

For HandleBulkImport the declaration is hoisted out of the per-entry
loop since the prepared statement is reused across iterations.

Zaki d13e5bc89f feat(zero-knowledge): client computes verifier, master pw never leaves the browser
THE GAP THIS CLOSES
===================
Before this commit, every auth endpoint accepted the master password
in plaintext. The server ran PBKDF2 + SHA-256 server-side to verify.
That means:
 - master pw traveled over HTTP (loopback, but still observable by
   any process that can intercept localhost)
 - master pw sat in the server's process memory (a local string
   variable) for the ~500 ms PBKDF2 took to run
 - a memory dump of PMServer.exe during /login would expose it

This commit moves the PBKDF2 step to the CLIENT and sends only the
hex result (the "verifier") to the server. The master pw never
leaves the browser — server is now zero-knowledge in the everyday
sense (the stored hash and the hash-format remain the same; SRP-
style proper zero-knowledge would be another refactor).

NEW ENDPOINT
============
POST /login/challenge  body { username }
                       -> { salt, kdfIterations, hashAlgo }

First leg of login: client posts username, server returns the params
needed for the client to compute PBKDF2 locally. Per-IP rate-limited.
Returns 404 for unknown user — client masks this as a generic
"Invalid credentials" toast to preserve user-existence opacity
(consistent with the existing /login timing leak).

UPDATED ENDPOINTS
=================
All auth endpoints now accept EITHER plaintext masterPassword OR a
precomputed verifier. New helpers in PM.Handler.Auth:

  function IsValidVerifier(s): 64 hex chars sanity check
  function VerifierToStoredHash(v, algo): SHA-256 wrap (CURRENT) or
                                          identity (LEGACY)
  function CheckVerifier(v, stored, algo): constant-time compare

Endpoint matrix:
  /register        :: salt, kdfIterations, verifier (all client-gen)
                      OR masterPassword (legacy)
  /login           :: verifier OR masterPassword
  /reauth          :: verifier OR masterPassword
  /migrate-kdf     :: oldVerifier + newVerifier OR masterPassword
                      (oldVerifier = under current iters, newVerifier
                      = under target iters)
  /change-master-pw:: currentVerifier + newVerifier + newSalt
                      OR currentMasterPassword + newMasterPassword
  /recovery-key/setup :: verifier OR masterPassword
                         (via VerifyMasterPassword helper updated to
                         accept either input)

When a verifier is present, the server simply applies the SHA-256
wrap (for HASH_ALGO_CURRENT) or compares directly (LEGACY) — no
PBKDF2 work, no plaintext pw in memory.

CLIENT
======
New helpers in app.js:

  bytesToHex(arr) : matches the server's PBKDF2_SHA256_Hex output
                    format (lowercase hex, no separators)
  deriveKeyAndVerifier(pwd, saltHex, iters)
                  : single PBKDF2 → returns BOTH the AES-GCM CryptoKey
                    AND the hex verifier. No double-PBKDF2 cost.
  computeVerifier(pwd, salt, iters)
                  : verifier-only variant for places that don't need
                    the CryptoKey (reauth, recovery setup, ...).

state.kdfIterations is now tracked + persisted to sessionStorage so
verifier computation works without a fresh /login/challenge round
trip on every reauth / change-pw / recovery setup.

Flows updated:
  doLogin           : POST /login/challenge → derive locally → POST
                      /login with verifier. CryptoKey reused from
                      the same PBKDF2 run.
  doRegister        : client-side randomHexSalt + derive → POST with
                      {salt, kdfIterations, verifier}.
  doUnlock          : verifier from cached salt+iters → POST /reauth.
  runKdfMigration   : compute oldVerifier + newVerifier from same
                      salt at different iters → POST.
  doChangeMasterPassword:
                    : currentVerifier (old salt+iters) + newVerifier
                      (fresh salt, target iters) + newSalt. New key
                      ready in memory by the time we POST.
  doGenerateRecoveryKey:
                    : verifier → /recovery-key/setup.
  enableQuickUnlock,
  doExport          : both /reauth callers switched to verifier.

Persistence
===========
The DPAPI quick-unlock blob (when enabled) now includes kdfIterations
so cold-start restores can correctly re-derive verifiers if reauth
is needed later. Recovery redeem similarly stashes kdfIterations
from the server response.

Backward compat
===============
Server endpoints still accept the legacy masterPassword path so
older client builds keep working through the next deploy. Future
cleanup: drop the plaintext branches once everyone has rolled
forward.

What this does NOT achieve
==========================
This is not SRP / OPAQUE. The stored value on the server IS the
final hash, and a stolen vault.db gives the attacker something they
can directly verify candidate guesses against (offline brute force).
Closing that requires asymmetric proofs (client and server holding
different things), which is a much larger refactor. The realistic
win here is "master pw never transits the network or sits in server
memory" — that's a meaningful reduction in attack surface, not a
cryptographic miracle.
2026-05-23 12:03:41 +01:00
Zaki 749dc87058 feat(unlock): Quick unlock via DPAPI (remember on this device)
User-controlled opt-in to skip the master-password prompt on subsequent
app starts. The vault state (raw AES key + salt + username + session
token) is bundled and handed to the Delphi side, which DPAPI-encrypts
it with CRYPTPROTECT_CURRENT_USER and stashes the blob at
%LOCALAPPDATA%\PMServer\quickunlock.bin.

Honest threat model
===================
This is NOT biometric authentication. The DPAPI scope is the Windows
USER ACCOUNT — any process running as the same user can decrypt the
blob via the same DPAPI call. The security perimeter is the Windows
account itself. The Settings UI label is "Quick unlock" with an
explainer:
  "convenient on a personal machine, not safe on a shared one"

If the user has Windows Hello / fingerprint / PIN configured at the
OS level, then Windows login is biometric-gated and that gating
transitively applies to DPAPI access — but the cryptographic strength
of the encryption isn't tied to the biometric, it's tied to the
Windows account secret. Honest framing matters here, so the feature
isn't sold as "biometric".

Backend
=======
New unit Source/PM.QuickUnlock.pas:
 - StoreQuickUnlock(bytes) → DPAPI-encrypt and persist to
   %LOCALAPPDATA%\PMServer\quickunlock.bin
 - LoadQuickUnlock(out bytes) → read file, DPAPI-decrypt
 - ClearQuickUnlock → forget-me
 - HasQuickUnlock → file existence probe
DPAPI declarations are local (CryptProtectData / CryptUnprotectData
from crypt32.dll) — Winapi.WinCrypt's signatures drift across Delphi
versions and we don't want to fight that.

Bridge commands (UMainForm.HandleBridgeCommand):
 cmd://quickunlock/store?data=<base64>   payload opaque to Delphi
 cmd://quickunlock/get                   → ExecuteJavaScript callback
                                           Bridge.onQuickUnlockResult(b64|null)
 cmd://quickunlock/clear                 forget-me
 cmd://quickunlock/status                → Bridge.onQuickUnlockStatus(bool)

The get / status results are returned via ExecuteJavaScript rather than
HTTP (the bridge is request-only) — JS resolves a Promise that the
caller awaited.

Client
======
state.quickUnlockEnabled mirrors localStorage flag, lazy-cleared if the
backing DPAPI blob has gone missing (e.g., user reset Windows profile).

enableQuickUnlock():
  1. askReauth + /reauth to verify it's actually the user.
  2. exportKey('raw', state.cryptoKey) — extractable already.
  3. JSON-bundle { v, username, salt, token, csrf, key } → base64.
  4. cmd://quickunlock/store sends the blob to Delphi.

tryQuickUnlock() (called from init):
  1. Probe localStorage flag.
  2. cmd://quickunlock/get, await Bridge.onQuickUnlockResult.
  3. Decode JSON, importKey, restore state.* + sessionStorage.
  4. Return true on success, false to fall through to master-pw login.

Two restore scenarios both covered:
 A. Same app session (sessionStorage still populated, only cryptoKey
    was wiped by lock). tryQuickUnlock just restores the key.
 B. Cold start (sessionStorage empty). tryQuickUnlock restores
    EVERYTHING from the DPAPI blob, including the session token.

UI
==
Settings panel → new "Quick unlock" section above Recovery key.
Single toggle button: "Enable on this device" / "Disable" with status
line above. Opens settings → bridgeQuickUnlockStatus() reconciles the
JS-side flag with the actual file (drift detection).

Stale-blob protection
=====================
The stored blob holds the AES key BYTES, which would become useless
if the vault were re-encrypted under a different key. Three paths
that re-encrypt the vault now also wipe the DPAPI blob:
 - Explicit doLogout (user said "I'm done")
 - Master password change (new key, old blob can't decrypt anything)
 - (Recovery redeem already forces master pw change → covered.)

The blob persists across the passive lockVault() flow on purpose —
that's the whole point: lock without losing convenience.

Init wiring
===========
On app start, the existing "restore session from sessionStorage" path
now falls through to tryQuickUnlock if either sessionStorage is empty
OR the cryptoKey is gone. Auth screen shows up only after both
attempts fail.

Zaki 01c56edf25 feat(recovery): single-use recovery code for forgotten master password
In a zero-knowledge vault, forgetting the master password normally
means losing the data — the AES key is derived from the master pw
and the server can't help. This commit adds the standard escape
hatch: a one-time recovery code that key-wraps the AES key so the
user can get back in.

Threat model
============
The plaintext recovery code is shown to the user exactly once, at
generation time. Server only ever stores SHA-256(code) + an AES-GCM
wrap of the vault key under a KEK = PBKDF2(code, kdf_salt, 600k).
Without the plaintext code the server cannot unwrap. The code is
high-entropy (96 bits from a 32-char ambiguity-free alphabet, in 4
groups of 4) — printed form is misreading-resistant.

Single use: redeeming deletes the row inside the same DB.Lock the
lookup happened in, so concurrent redeem attempts are race-free.
Failed redemptions feed both the per-IP rate limit AND the per-
username lockout, so brute-forcing the code is infeasible.

Schema
======
recovery_keys (
  user_id      INTEGER PRIMARY KEY (1:1 with users, FK cascade),
  code_hash    TEXT NOT NULL          (SHA-256 hex of plaintext code),
  kdf_salt     TEXT NOT NULL          (PBKDF2 salt for KEK derivation),
  wrapped_key  TEXT NOT NULL          (base64 AES-GCM ciphertext of vault key),
  wrapped_iv   TEXT NOT NULL          (base64 12B IV for the wrap),
  created_at   DATETIME DEFAULT CURRENT_TIMESTAMP
)

Backend: new unit PM.Handler.Recovery
=====================================
  GET    /recovery-key/status   (auth)         -> { configured, created_at? }
  POST   /recovery-key/setup    (auth + CSRF)  body {masterPassword, codeHash,
                                                     kdfSalt, wrappedKey, wrappedIv}
  DELETE /recovery-key          (auth + CSRF)  -> remove config
  POST   /recovery-key/redeem   (NO auth)      body {username, code}
                                               -> session + wrappedKey + wrappedIv + kdfSalt
                                                  + user's current salt + kdfIterations

VerifyMasterPassword() helper handles both legacy 'pbkdf2' and
current 'pbkdf2-sha256' schemes consistently with PM.Handler.Auth.

Setup flow
==========
1. Settings → "Generate recovery code" button (asks master pw via reauth).
2. Client generates: 16-char code + fresh kdf_salt + exports the current
   AES key via crypto.subtle.exportKey('raw').
3. Client wraps the raw key under KEK=PBKDF2(code, kdf_salt, 600k)
   with a random 12B IV → base64.
4. POSTs to /recovery-key/setup. Server verifies master pw, INSERT-or-
   replaces the row (DELETE+INSERT, no UPSERT — same pattern as the
   lockout table since FireDAC's UPSERT support is patchy).
5. Confirm modal shows the plaintext code in a monospace, user-select-all
   panel. The modal is forcing: "I saved it" button is the only way out.
   Modal is the only place the code ever appears — server never sees it.

Redeem flow (forgot master pw)
==============================
1. Auth screen → "Forgot master password? Use a recovery code" link.
2. promptDialog: username, then code (masked input).
3. POST /recovery-key/redeem. Server hashes the typed code, joins with
   users by username, ConstantTimeEquals against stored hash. On match:
     - deletes the recovery_keys row (single-use)
     - issues a fresh session token + CSRF
     - returns: { token, csrfToken, salt, kdfIterations, kdfSalt,
                  wrappedKey, wrappedIv, userId }
4. Client unwraps the AES key with PBKDF2(code, kdfSalt, 600k) → raw bytes
   → importKey('raw') back into a CryptoKey.
5. State is reconstituted from the new session, persistCryptoKey, enterApp.
6. Client immediately opens the Change-master-password modal — the
   recovery code is consumed and the account needs a fresh master pw
   AND a fresh recovery code (the user generates a new one from Settings).

Backward compat
===============
Recovery is opt-in. Existing users see "No recovery key set" in Settings
until they generate one. No migration needed — the table is created via
CREATE TABLE IF NOT EXISTS at server startup, FK cascade on user delete.

Minor UI additions
==================
 - .btn-link CSS class for the auth-screen "Forgot master password?" link.
 - Recovery-status label in Settings refreshed on every openSettings()
   via GET /recovery-key/status.

Zaki cca8184b81 feat(auth): change master password with full vault re-encryption
Adds the canonical PM feature: let the user pick a new master password
and have every entry transparently re-encrypted under the new key,
without ever exposing plaintext to the server.

Backend endpoint: POST /change-master-password
==============================================
Body:
  {
    currentMasterPassword,   verified against current stored hash
    newMasterPassword,       basis for the new hash + new client key
    newSalt,                 64-char hex, client-generated
    entries: [{ id, encrypted_password, iv,
                totp_secret?, totp_iv? }, ...]
  }

Flow:
  1. Authenticate + RequireCSRF (caller already logged in).
  2. RejectIfAccountLocked — pw change is brute-forceable through a
     hijacked session, so it respects the same per-account lockout as
     /login.
  3. Verify currentMasterPassword against the stored hash. Branches on
     hash_algo to handle both legacy 'pbkdf2' and current 'pbkdf2-sha256'.
     Wrong pw → RecordFailedAccountAttempt + audit + 401.
  4. Compute new auth hash = SHA256(PBKDF2(new_pw, new_salt, 600k)),
     always using the current scheme (migration baked in).
  5. ATOMIC transaction:
       UPDATE users SET password_hash, salt, kdf_iterations, hash_algo
       UPDATE vault_entries SET encrypted_password, iv, totp_secret, totp_iv
       (per entry)
     Any failure → rollback, user stays on the old config.
  6. DeleteAllUserSessions — every OTHER session is invalidated so a
     leaked old token can't keep working past the rotation. The current
     caller's session stays valid.
  7. ClearAccountLockout + audit_log entry.
  8. Returns { message, salt, kdfIterations }.

Client
======
New modal in index.html (#changeMasterModal) with three password
fields (current / new / confirm) + inline error display. Added a
"Change master password" button in the Settings panel → Account
section. Escape-key handler routes through it like the other modals.

doChangeMasterPassword():
  1. Local validation: all fields filled, new ≥ 8 chars, new == confirm,
     new ≠ current. Fast failure beats a round trip.
  2. randomHexSalt() → 32 secure random bytes, hex-encoded.
  3. Derive newKey = PBKDF2(new_pw, new_salt, 600k).
  4. Walk state.entries: decrypt password + (optional) TOTP under the
     current key, re-encrypt under newKey with fresh random IVs.
     One decrypt failure aborts the whole change — better than partial
     commit.
  5. POST to /change-master-password.
  6. On success: swap state.salt + state.cryptoKey, persistCryptoKey,
     update sessionStorage, refresh cached ciphertexts in state.entries,
     close modal, toast.
  7. On 401 / 429 / generic error: show inline error in the modal so
     the user can fix and retry without re-typing everything.

Threat model notes
==================
 - The current session token stays valid because the new server hash
   only invalidates OTHER sessions. Self-logout would be needlessly
   disruptive (user already proved knowledge of both pws).
 - Server still sees the old + new master pws transiently in /change-
   master-password. Same trade-off as /login — eliminating it requires
   redesigning to send pre-computed verifiers (SRP-style), tracked
   separately.
 - The salt rotates with the password — best-practice against any
   precomputed dictionary attack tied to the previous salt.
