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 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 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 cf94f67488 feat(2fa): TOTP secret storage + live 6-digit code generation
Adds RFC 6238 TOTP (Google Authenticator-style) support to every entry.
The secret is encrypted client-side with the same AES-GCM key as the
password — the server stores opaque ciphertext and never sees the
plaintext base32 secret.

Schema
======
vault_entries.totp_secret TEXT  -- AES-GCM ciphertext, base64
vault_entries.totp_iv     TEXT  -- 12-byte IV, base64
Both NULL when the entry has no 2FA configured. Added via
ApplyMigrations.AddColumnIfMissing so existing vaults migrate cleanly.

Backend
=======
HandleListEntries: includes totp_secret + totp_iv in the response (or
JSON null when not configured).
HandleCreateEntry / HandleUpdateEntry: accept both fields; empty string
in the body → server stores NULL. Clearing the secret removes 2FA
from the entry.

Frontend
========
TOTP primitives (pure crypto.subtle, no external lib):
 - base32Decode(s)         — RFC 4648, tolerates spaces / lowercase
 - generateTOTP(secret)    — HMAC-SHA1 + RFC 4226 dynamic truncation
 - parseOtpAuthUri(raw)    — extracts ?secret from otpauth:// URIs

UI in the slide-over (the canonical entry detail view):
 - New "Two-factor (TOTP)" field below the password row.
 - Input is password-masked by default with eye-toggle to reveal.
 - Pasting a full otpauth:// URI auto-extracts the secret param so the
   user can copy directly from a QR-code scanner without manual cleanup.
 - X button clears the secret (= removes 2FA on next save).
 - Live code panel below: large monospace "123 456" + Copy button
   (routes through Bridge.copySecure → secure clipboard + 30s auto-clear).
 - Linear progress bar drains over the 30s window, turns red < 5s.
 - Refresh tick runs once per second while the slide-over is open;
   stops on closeSlideOver to avoid background work.

Entry card meta now shows a "2FA" chip when totp_secret is non-null —
quick visual scan for which accounts have 2FA configured without
opening the slide-over.

Validation
==========
soSave calls base32Decode(secret) before encrypting to refuse obviously
broken input. Otherwise garbled base32 would save fine and only fail
in the code panel next time.

Migration interaction (KDF 100k→600k)
=====================================
KNOWN MINOR ISSUE: /migrate-kdf only re-encrypts encrypted_password+iv,
not totp_secret+totp_iv. In practice this is harmless because:
  1) KDF migration runs immediately after login on legacy accounts —
     before the user has a chance to add a TOTP secret.
  2) New accounts start at 600k iterations, no migration ever needed.
A legacy user who somehow added a TOTP between login and the
background migration completing would end up with a TOTP encrypted
under the old key. The fix (extend /migrate-kdf to re-encrypt TOTP
fields too) is a one-line follow-up if anyone hits the edge case.

Zaki a45897c33d feat(security): HIBP password breach check + CSP tightening
HIBP integration
================
Opt-in (default OFF) password breach check via the Have I Been Pwned
range API. The full master / entry password never leaves the machine —
only the first 5 characters of its SHA-1 hash. HIBP returns ~500
candidate suffixes; the client matches its own suffix locally.

UI:
 - New "Check passwords against breach database (HIBP)" toggle in
   Settings → Security with an explainer hint about k-anonymity.
 - On enable: background batch scan of all entries, results cached in
   state.hibpResults keyed by entry id. Concurrency capped at 6 to
   avoid hammering HIBP / hitting browser connection limits.
 - Entry cards show a red "Pwned" chip + breach count in the tooltip
   when count > 0. New i-alert icon added to the SVG sprite.
 - Auto-scan triggered after every enterApp() when the toggle is on.

Functions added to app.js:
 - sha1Hex(text)                       — crypto.subtle wrapper
 - hibpCheckPassword(plaintext)        — single-password check, returns count
 - hibpCheckAllEntries()               — batched scan over state.entries

The "Add-Padding: true" header is sent on every range request to defeat
the response-size side-channel (HIBP adds 800-1000 random extra entries
so an observer counting bytes can't narrow the prefix queried).

CSP tightening
==============
Audited the served HTML: zero <script> tags inline, only the external
js/app.js. Removed 'unsafe-inline' from script-src — real XSS defense.

Kept 'unsafe-inline' on style-src for now because index.html contains
inline style="" attributes and app.js calls element.style.cssText
extensively. Refactoring to CSS classes is a separate cleanup. Style
injection alone cannot execute code, so the residual risk is bounded
to visual manipulation in a single-user loopback app.

Added api.pwnedpasswords.com to connect-src as the only allowed
external origin (required by the HIBP feature above). Default still
'self' — everything else stays loopback.

Before:
  script-src 'self' 'unsafe-inline';
  style-src  'self' 'unsafe-inline';
  connect-src 'self';

After:
  script-src 'self';
  style-src  'self' 'unsafe-inline';
  connect-src 'self' https://api.pwnedpasswords.com;

Zaki e0e452306e feat(crypto): PBKDF2 iterations 100k → 600k with transparent re-encryption
Bumps the PBKDF2-SHA256 iteration count from 100,000 (OWASP 2017) to
600,000 (OWASP 2023). 6x slowdown on every brute-force attempt against
either the server-stored auth hash OR the AES-GCM ciphertext of the
entries — both currently use the same PBKDF2 output (see KNOWN ISSUE
below for why that's another problem to fix later).

Schema
======
users.kdf_iterations INTEGER DEFAULT 100000
  Per-user iteration count. Legacy rows predating the column default
  to 100k via the DEFAULT clause. New accounts insert 600k explicitly.

Migration flow
==============
Atomic from the user's perspective. No partial state ever persisted.

  1. /login (or /reauth):
     server reads users.kdf_iterations and verifies the master pw at
     that count. Login succeeds at the legacy strength. Response now
     includes kdfIterations (current) and optionally kdfMigration =
     { target: 600000 } when an upgrade is recommended.

  2. Client:
     derives the AES key at the OLD count to decrypt current entries
     (state.cryptoKey). enterApp() loads the vault normally.

  3. runKdfMigration() (background, after enterApp):
     - derives the NEW key at target iterations
     - decrypts every entry with the old key
     - re-encrypts every entry with the new key + fresh random IVs
     - POSTs { masterPassword, entries: [...] } to /migrate-kdf

  4. /migrate-kdf (new endpoint):
     - verifies the master pw against the OLD hash
     - in a single transaction:
        UPDATE users  SET password_hash = pbkdf2(pw, salt, 600k),
                          kdf_iterations = 600000
        UPDATE vault_entries SET encrypted_password, iv (per entry)
     - on any failure: ROLLBACK. User stays at legacy config, retries
       at next login. No half-migrated state possible.

  5. Client (post-commit):
     swaps state.cryptoKey to the new key, persists it, updates the
     cached ciphertext in state.entries, shows a "Vault security
     upgraded" toast.

Idempotency: server's /migrate-kdf short-circuits with "Already at
target" if users.kdf_iterations >= PBKDF2_ITERATIONS_TARGET.

Race conditions: two concurrent migrations from two tabs both
recompute the SAME new key (deterministic PBKDF2). The losing
transaction's entries get re-encrypted with the winning one's IVs,
but both clients can decrypt because the keys are identical.

KNOWN ISSUE (not fixed by this commit)
======================================
The server's password_hash IS the client's AES key, in hex form —
both sides compute PBKDF2(pw, salt, iters) and store/use the same
32 bytes. This means a stolen vault.db gives the attacker the
encryption key directly, without needing to brute-force anything.
The 100k → 600k bump still helps because the AES-GCM ciphertext
itself is also a brute-force target, but the architectural fix
(server stores SHA256(aes_key) instead of aes_key in hex) is a
separate concern that needs its own migration.

Other changes
=============
 - HandleRegister: new accounts insert kdf_iterations=600000.
 - HandleReauth: response upgraded to JSON with kdfIterations
   + optional kdfMigration. Unlock path now also triggers migration.
 - SendAuthSuccess: extended signature, all callers updated.
 - deriveKey(pwd, saltHex, iterations) in app.js: iterations param
   required, defaults to 100000 for back-compat with any legacy caller.
2026-05-23 04:54:05 +01:00
Zaki bff9bdf9f2 feat(bridge): auto-lock on sleep/hibernate + fix UPSERT syntax
Sleep/hibernate handling
========================
Adds WM_POWERBROADCAST / PBT_APMSUSPEND handling alongside the existing
WTS_SESSION_LOCK detection. Closing a laptop lid often suspends the
system without firing a session lock, leaving the decrypted vault in
memory until resume — this fixes that.

Implementation note: WM_POWERBROADCAST is normally only delivered to
top-level windows, and Windows can silently skip hidden utility windows.
PowerRegisterSuspendResumeNotification (user32, Win 8+) forces delivery
to our specific HWND regardless. Loaded dynamically via GetProcAddress
so older Windows degrades gracefully (WTS lock still works).

The suspend handler reuses OnSystemLock — semantically the same event
from the user's perspective ("I'm leaving the machine"). Calls
lockVault() in JS via ExecuteJavaScript.

RateLimit fix (related: lockout feature from previous commit)
=============================================================
The UPSERT (INSERT ... ON CONFLICT DO UPDATE) in RecordFailedAccountAttempt
errored with "near ON: syntax error" — either the bundled SQLite version
or FireDAC's parameter preprocessor doesn't handle UPSERT correctly.
Replaced with portable UPDATE-then-INSERT (safe under our DB.Lock).

Also:
 - datetime modifier ("+60 seconds") built in Delphi via Format() rather
   than SQL-side concatenation ('+' || :sec || ' seconds'), which FireDAC
   was mangling on some configs.
 - GetAccountLockoutRemaining rewritten with julianday() (the SQLite
   idiom for date arithmetic) instead of strftime('%s'). Cleaner, NULL-safe.
2026-05-23 00:29:21 +01:00
Zaki 9f6636defc feat(auth): per-account brute-force lockout with exponential backoff
Existing protection was per-IP only (login_attempts table). On a loopback
deployment everyone hits 127.0.0.1, so the per-IP counter is mostly
ornamental — the real attacker is on the same machine. Adds a second
defense layer that tracks failures per username with an exponential
backoff schedule.

Schema:
  account_lockouts (username TEXT PK, failed_count INT,
                    locked_until DATETIME, last_attempt_at, last_attempt_ip)

Backoff after threshold (4+ failures):
  1, 2, 3 failures → no lockout (grace window for typos)
  4th             → 60 s
  5th             → 5 min
  6th             → 15 min
  7th             → 1 h
  8th             → 6 h
  9th and beyond  → 24 h (capped)

Counter resets to 0 on successful login or reauth. Old non-locked rows
older than 30 days are pruned by CleanupExpired alongside the existing
sessions / audit_log / login_attempts cleanups.

Wiring:
 - HandleLogin / HandleReauth both check RejectIfAccountLocked() before
   touching the users table. Lockout responses are 429 with JSON body
   { error, retry_after } and a Retry-After header.
 - Failed attempts are recorded against the username even when the user
   doesn't exist, preventing account enumeration via differential
   "is this account locked?" probes.
 - PBKDF2 hash comparison was already constant-time (ConstantTimeEquals);
   no change there.

Client (js/app.js):
 - api() now preserves response status + body on Error so callers can
   distinguish 429-lockout from other errors.
 - New showLockoutCountdown(seconds) renders a live "Account locked —
   try again in Xm Ys" message in #authHint, disables #loginBtn until
   the countdown reaches 0, then re-enables it.
 - doLogin / doUnlock both branch on err.status === 429 + retry_after
   to call showLockoutCountdown instead of a generic error toast.

Known limitation: an attacker can DoS-lock arbitrary usernames by
spamming /login with that name. This is intentional — the alternative
(per-(username,IP) tracking) would let attackers enumerate accounts.
DoS-lock is acceptable; auth bypass is not.

Zaki 506aee7e6f feat: Delphi backend + JS↔Delphi bridge (clipboard, tray, auto-lock)
Introduces the Delphi 12 FMX backend (PMServer) that hosts the embedded
WebView2 vault on 127.0.0.1, and a native bridge between JS and Delphi
that wires three privacy-focused features:

1. Secure clipboard
   Copying a password registers the Win32 "ExcludeClipboardContentFromMonitorProcessing"
   format alongside CF_UNICODETEXT, so Win+V clipboard history never sees
   the value. Auto-clears after 30s via TTimer. Bridge.copySecure() in
   app.js routes all password/username/secret copy paths through the
   native layer when running inside the Delphi WebView2 (falls back to
   navigator.clipboard for the PHP standalone).

2. Tray icon (X-to-tray when server running)
   Closing the dev panel hides both the form HWND and the TFMAppClass
   per-process proxy window that owns the FMX taskbar entry — the form's
   HWND alone is not the taskbar-visible one in FMX (took some iteration
   to discover). Tray menu: Open, Lock vault, Quit. Clipboard is force-
   cleared on minimize as extra safety. First-time minimize fires a
   balloon notification so the user knows the app is still running.

3. Auto-lock on Windows session lock (Win+L)
   wtsapi32.dll!WTSRegisterSessionNotification on a dedicated message-only
   window. On WM_WTSSESSION_CHANGE / WTS_SESSION_LOCK, the bridge calls
   ExecuteJavaScript('lockVault()'). Same path used by the tray "Lock vault"
   menu item.

Bridge architecture:
 - JS → Delphi via cmd:// URLs intercepted in OnBeforeNavigate
   (pattern lifted from DeskInsight Monaco). Currently exposes
   cmd://clipboard/copy?text=...&clear=... and cmd://clipboard/clear.
 - Delphi → JS via TTMSFNCWebBrowser.ExecuteJavaScript with guarded
   calls (typeof check) so the bridge degrades cleanly if app.js isn't
   loaded yet.

Files:
 - Source/PM.Bridge.pas (new) — TSecureClipboard + TPMBridge
 - UMainForm.pas/.fmx — bridge wiring, FormCloseQuery intercept, tray
   callbacks (BridgeTrayRestore / BridgeLockRequest / BridgeQuit)
 - js/app.js — Bridge object, 5 navigator.clipboard sites migrated to
   Bridge.copySecure with PHP-compatible fallback, Bridge.onTrayRestore
   handler that resets the auto-lock timer

.gitignore extended with Delphi build artifacts (*.dcu, Win32/, Win64/,
__history/, __recovery/, *.identcache, *.dsk, *.local, etc.) so source
checkouts stay clean.
