Authenticate/RequireCSRF write a 401 then raise ESessionRejected; when it
reached the dispatcher catch-all, the generic `on E: Exception` overwrote it
with a 500. Added `on ESessionRejected do Exit` before the generic clause in
both dispatchers (GET + Other) — one place, covers every handler whether or
not it wraps Authenticate. Root cause, not per-handler patch.
ponytail: runtime check only (expired token → 401) — no Delphi unit harness.

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.

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;
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.
