+## Dashboard ANAF - Detalii Modificări
+
+**Context:** Marius a cerut să vadă ce modificări detectează ANAF Monitor în dashboard, nu doar mesaj generic "Modificări detectate".
+
+**Implementare:**
+1. **monitor_v2.py** - modificat `update_dashboard_status()` să salveze detalii în `status.json`:
+   - Nume pagină modificată
+   - URL către pagina ANAF
+   - Rezumat modificări (ex: "Soft A: 09.02.2026 → 10.02.2026")
+
+2. **dashboard/index.html** - modificat `loadAnafStatus()` să afișeze detaliile:
+   - Link-uri clickabile către paginile ANAF
+   - Lista modificărilor pentru fiecare pagină
+   - Expandabil în secțiunea ANAF Monitor
+
+**Modificare reală detectată astăzi:**
+- D100 (Declarația 100) - Soft A: 09.02.2026 → 10.02.2026
+
+**Status:** Implementat, netestat în browser. Așteaptă commit.

+# Antfarm Workflow - Echo
+
+**Instalat:** github.com/snarktank/antfarm  
+**CLI:** `antfarm` (în PATH, global)  
+**Dashboard:** https://moltbot.tailf7372d.ts.net:3333  
+**Docs:** ~/clawd/antfarm/README.md, ~/clawd/antfarm/docs/creating-workflows.md
+
+---
+
+## Flux rapid (pentru Echo)
+
+### 1. Primesc request de la Marius
+**EX:** "Vreau să construiesc un Habit tracker în dashboard"
+
+### 2. Lansez direct workflow-ul cu promptul lui Marius
+```bash
+cd ~/clawd
+antfarm workflow run feature-dev "<prompt exact de la Marius>"
+```
+
+**NU:**
+- ✗ Verific dacă e instalat (e instalat, permanent)
+- ✗ Fac eu requirements/acceptance criteria (planner-ul face asta)
+- ✗ Complicez task string-ul (simplitate = mai bine)
+
+**DA:**
+- ✓ Trimit prompt-ul EXACT cum îl primesc de la Marius
+- ✓ Planner-ul descompune în stories automat
+- ✓ Developer-ul decide tehnologii/structură
+
+### 3. Monitorez progres
+```bash
+antfarm workflow status <run-id sau substring>
+antfarm workflow runs  # listă toate
+```
+
+### 4. Raportez când e gata
+Agenții lucrează autonom (polling 15 min). Raportez când:
+- Stories finalizate
+- Erori care necesită intervenție
+- PR creat pentru review
+
+---
+
+## Workflows disponibile
+
+| Workflow | Când să-l folosesc |
+|----------|-------------------|
+| `feature-dev` | Features noi, refactoring, îmbunătățiri |
+| `bug-fix` | Bug-uri cu pași de reproducere |
+| `security-audit` | Audit securitate codebase |
+
+---
+
+## Comenzi utile
+
+```bash
+# Status rapid
+antfarm workflow status <query>
+
+# Force trigger agent (skip 15min wait)
+cron action=run jobId=antfarm/feature-dev/developer
+
+# Logs
+antfarm logs 50
+
+# Resume dacă failuit
+antfarm workflow resume <run-id>
+
+# Dashboard
+antfarm dashboard status
+```
+
+---
+
+## Reguli importante
+
+1. **Task string = prompt exact de la Marius** (nu complica)
+2. **Planner face requirements** (nu tu)
+3. **Agenții sunt autonomi** (polling 15 min, nu trebuie să-i controlezi)
+4. **Monitor dashboard** (https://moltbot.tailf7372d.ts.net:3333)
+5. **Raportează doar când e relevant** (finalizare, erori, PR)

+    - Added mobile responsiveness with @media (max-width: 768px) query
+    - Mobile styles: full width cards, reduced padding, smaller icons (36px, 28px)
+    - All CSS uses CSS variables for theming consistency
+    
+    Tests:
+    - Created dashboard/test_habits_card_styling.py with 10 comprehensive tests
+    - Tests for file existence
+    - Tests for card using --bg-surface with --border (acceptance criteria 1)

+    - Added do_DELETE method to api.py for handling DELETE requests
+    - Route: DELETE /api/habits/{id} deletes habit by ID
+    - Extracts habit ID from URL path (/api/habits/{id})
+    - Returns 404 if habit not found in habits.json
+    - Removes habit from habits array using list.pop(index)
+    - Updates lastUpdated timestamp after deletion
+    - Returns 200 with success message, including deleted habit ID
+    - Graceful error handling for missing/corrupt habits.json (returns 404)
+    - Follows existing API patterns (similar to handle_habits_check)
+    - Error responses include descriptive error messages
+    
+    Tests:
+    - Created dashboard/test_habits_delete.py with 6 comprehensive tests
+    - Tests for habit removal from habits.json file (AC1)
+    - Tests for 200 status with success message response (AC2)
+    - Tests for 404 when habit not found (AC3)
+    - Tests for lastUpdated timestamp update (AC4)
+    - Tests for edge cases: deleting already deleted habit, invalid paths
+    - Tests for graceful handling when habits.json is missing
+    - All 6 tests pass ✓ (AC5)
+    - All previous tests (schema, GET, POST, streak, check) still pass ✓
+    
+    Files modified:
+    - dashboard/api.py (added do_DELETE method and handle_habits_delete)
+    - dashboard/test_habits_delete.py (created)

+[✓] Story 16.0: Frontend - Delete habit with confirmation
+    Commit: 46dc3a5
+    Date: 2026-02-10
+    
+    Implementation:
+    - Added delete button with trash icon (lucide trash-2) to each habit card
+    - Delete button styled with 32x32px size, border, hover state with red color
+    - Hover state changes border and background to danger color (rgba(239, 68, 68, 0.1))
+    - Created delete confirmation modal (id='deleteModal') with modal-overlay pattern
+    - Confirmation modal shows message: "Ștergi obișnuința {name}?" with habit name
+    - Modal includes Cancel button (btn-secondary) and Delete button (btn-danger)
+    - Delete button uses destructive red styling (.btn-danger class)
+    - Added showDeleteModal(habitId, habitName) function to display confirmation
+    - Added hideDeleteModal() function to close modal
+    - Added confirmDelete() async function to execute DELETE API call
+    - Delete button disabled during deletion with loading text "Se șterge..."
+    - On successful delete: hides modal, shows success toast, reloads habits list
+    - On error: shows error toast, re-enables delete button, keeps modal open
+    - Habit name properly escaped for XSS protection when passed to modal
+    - All styling uses CSS variables for theme consistency
+    
+    Tests:
+    - Created dashboard/test_habits_delete_ui.py with 10 comprehensive tests
+    - Tests for delete button CSS styling (size, border, hover, danger color) [AC1]
+    - Tests for trash-2 icon inclusion in habit cards [AC1]
+    - Tests for confirmation modal structure with Romanian message [AC2]
+    - Tests for Cancel and Delete buttons with correct handlers [AC3]
+    - Tests for btn-danger destructive red styling [AC4]
+    - Tests for DELETE API call to /api/habits/{id} endpoint [AC5]
+    - Tests for loadHabits() call after successful deletion (list refresh) [AC5]
+    - Tests for error handling with toast notification [AC6]
+    - Tests for modal show/hide functions and active class toggle
+    - Summary test verifying all 7 acceptance criteria [AC7]
+    - All 10 tests pass ✓
+    - All previous tests (schema, API endpoints, HTML, modal, display, check, form, styling, navigation, mobile) still pass ✓
+    
+    Files modified:
+    - dashboard/habits.html (added delete button, modal, CSS, and JavaScript functions)
+    - dashboard/test_habits_delete_ui.py (created)

+[✓] Story 17.0: Integration - End-to-end habit lifecycle test
+    Commit: bf215f7
+    Date: 2026-02-10
+    
+    Implementation:
+    - Created dashboard/test_habits_integration.py with comprehensive integration tests
+    - Main test: test_complete_habit_lifecycle() covers full habit flow
+    - Test creates daily habit 'Bazin' via POST /api/habits
+    - Checks habit today via POST /api/habits/{id}/check (streak = 1)
+    - Simulates yesterday's check by manipulating habits.json file
+    - Verifies streak calculation is correct (streak = 2 for consecutive days)
+    - Deletes habit successfully via DELETE /api/habits/{id}
+    - Verifies habit no longer exists after deletion
+    - Additional test: test_broken_streak() validates gap detection (streak = 0)
+    - Additional test: test_weekly_habit_streak() validates weekly habit streaks
+    - Tests use HTTP test server on port 8765 in background thread
+    - Comprehensive validation of all API endpoints working together
+    - Proper setup/teardown with habits.json reset before/after tests
+    
+    Tests:
+    - Created dashboard/test_habits_integration.py
+    - Main integration test passes all 5 steps (create, check, simulate, verify, delete)
+    - Tests for daily habit creation and checking (AC1, AC2)
+    - Tests for simulating yesterday's check and streak = 2 (AC3, AC4)
+    - Tests for habit deletion after lifecycle (AC5)
+    - Additional tests for broken streaks (gap > 1 day returns 0)
+    - Additional tests for weekly habit streak calculation (2 consecutive weeks)
+    - All tests pass ✓ (AC6)
+    - All previous tests (schema, API endpoints, HTML, modal, display, check, form, styling, navigation, mobile, delete) still pass ✓
+    
+    Files modified:
+    - dashboard/test_habits_integration.py (created)
