+## Session — 2026-02-28b (GitHub Copilot - Claude Opus 4.6)
+
+### Context
+
+User-requested improvements from QA testing: Registratura UX enhancements + Password Vault category rework.
+
+### Completed
+
+- **Registratura — Thread Explorer ("Fire conversație" tab):**
+  - New `thread-explorer.tsx` component with full thread timeline view
+  - Thread building via BFS from threadParentId chains
+  - Stats cards (total/active/completed/average duration)
+  - Search + status filter (toate/active/finalizate)
+  - Expandable timeline with directional nodes (blue=intrat, orange=ieșit)
+  - Gap day indicators showing "la noi" vs "la instituție" between entries
+  - Export to text report per thread with downloadReport()
+  - Integrated as new tab in registratura-module.tsx
+
+- **Registratura — Interactive I/O Toggle:**
+  - Replaced direction dropdown with visual button group (blue Intrat / orange Ieșit)
+  - Uses ArrowDownToLine/ArrowUpFromLine icons from lucide-react
+  - Full mutual-exclusive toggle with cn() conditional styling
+
+- **Registratura — Doc Type UX Fix:**
+  - Document types now sorted alphabetically by label
+  - After adding custom type, it's immediately selected (no manual re-selection needed)
+  - Uses localCustomTypes state to track session-added types
+
+- **Registratura — AC Validity Tracker:**
+  - New `ACValidityTracking` type system (phases, execution duration, required docs, reminders)
+  - New `ac-validity-tracker.tsx` component (~400 lines)
+  - Full AC lifecycle: issuance → validity (12mo) → execution → extension/abandonment/expiry
+  - Required documents checklist (CF notation, newspaper, site panel) with progress bar
+  - Extension request workflow (45 working days before expiry using addWorkingDays)
+  - Monthly reminders with snooze capability
+  - Pre-expiry warnings (30/60/90 days)
+  - Integrated into registry-entry-form.tsx
+
+- **Password Vault → "Parole Uzuale" (v0.3.0):**
+  - Renamed module from "Seif Parole" to "Parole Uzuale" everywhere (config, i18n, flags)
+  - New categories: WiFi, Portale Primării, Avize Online, PIN Semnătură, Software, Echipament HW (replaced server/database/api)
+  - Category icons (Globe, Mail, Wifi, Building2, FileCheck2, Fingerprint, Monitor, HardDrive) throughout
+  - WiFi QR dialog: displays WIFI:T:WPA;S:{ssid};P:{password};; connection string with copy
+  - Context-aware form: PIN vs password label, hides email for WiFi/PIN, hides URL for WiFi, hides generator for PIN
+  - Dynamic stat cards showing top 3 categories by entry count
+  - Removed encryption banner per user request
+  - Category descriptions as helper text in form
