v1.8.1

Fixed

• Credit card PII detection false positives — Luhn check alone is insufficient (Issue #694)

  • Added IIN/BIN prefix validation after Luhn check in _redact_credit_card()
  • Numbers starting with 0, 1, 7, 8, 9 (no major card network) are no longer flagged
  • Valid prefixes retained: Visa (4), Mastercard (51-55, 2221-2720), Amex (34, 37), Discover (6011, 65, 644-649), JCB (35), Diners Club (30, 36, 38, 39)
  • All-zeros and coincidental numeric IDs no longer trigger false positives

• Pause state not visually indicated — no countdown, no icon change, no CLI remaining time (Issue #684)

  • Tray icon now dims (50% alpha) when daemon is paused, reverts to normal on resume
  • Tray "Resume" menu item shows live countdown: Resume (3m 42s left)
  • Pause/Resume menu items are now mutually exclusive (Pause hidden when paused, Resume hidden when running)
  • ai-guardian daemon status now shows remaining time: (PAUSED — 3m 42s left) or (PAUSED — indefinite)
  • Console TUI daemon panel shows remaining time when paused
  • Connected existing _start_pause_timer() infrastructure to pause/resume actions
  • Added _sync_pause_state() to detect external pause/resume (e.g., via CLI) during periodic stats refresh

• macOS .app tray shortcut does not show menu bar icon on macOS 26.5 (Issue #691)

  • Set NSApplicationActivationPolicyAccessory explicitly before pystray creates the status bar item
  • Replaced bash wrapper script with Python wrapper to avoid exec chain losing bundle association
  • Added NSPrincipalClass: NSApplication to the .app bundle's Info.plist
  • Re-install shortcut with ai-guardian tray --uninstall && ai-guardian tray --install to apply

• Desktop shortcut/autostart launches tray with minimal PATH — scanners not found (Issue #689)

  • Added ensure_scanner_path() utility that augments PATH with common binary locations
  • Probes well-known directories (/opt/homebrew/bin, /usr/local/bin, ~/.local/bin) for scanner binaries
  • Reads user's login shell PATH as fallback for non-standard install locations
  • Called early in both daemon and tray startup
  • Fixed macOS .app wrapper script to augment PATH before exec
  • Fixed macOS launchd plist to include EnvironmentVariables with augmented PATH

• Tray pause does not work for local daemon (Issue #683)

  • Added pause and resume message handlers to daemon socket protocol in server.py
  • Fixed tray routing to use multi_client for local daemon targets instead of no-op callback
  • Replaced no-op pause_callback lambda in standalone tray with proper socket-based callback
  • Fixed auto-resume timer to route through multi_client when available

Changed

• Pattern research reminder frequency (Issue #681)
  • Changed from monthly (1st of month) to twice-monthly (1st and 15th)
  • Updated workflow cron schedule, issue title, and reminder text
  • Updated AGENTS.md documentation to reflect new frequency
