Le frontend etait lisible dans l'onglet Image de Process Explorer, avec
les commentaires. BuildAssets.ps1 brouille chaque fichier avant brcc32,
PM.EmbeddedAssets le debrouille au moment de servir.
C'est de l'opacite, pas du secret : la cle est dans l'exe. Ca supprime
strings et l'onglet Image ; la memoire, un debogueur et la reponse HTTP
rendent toujours le texte. D'ou XOR plutot qu'AES — a securite egale
(nulle contre qui a l'exe), dix lignes, et aucune force affichee qu'on
n'a pas.
Une magie PMA1 prefixe le clair : sans elle, deux constantes qui derivent
serviraient du binaire au navigateur, ecran blanc sans trace.
Verifie en comparant les flux des deux cotes bloc par bloc, puis par
aller-retour sur app.js, index.html et style.css. Le frontend ne se
trouve plus dans le binaire.

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.
