 ### Blocked items:
 - Visual validation blocked until we can run app_v2 via reflex (need to modify rxconfig or __init__.py)
 - For now, code validation is sufficient since components return correct types
 ## Iteration 4 - 2026-02-04
 ### Task: 2.2 Filter Section
 ### Why this task:
 - Previous iteration (3) completed Task 2.1 (top navigation bar)
 - Progress.txt explicitly recommended starting Task 2.2 as next step
 - Filter section is foundational for Phase 3 state management
 - Natural progression through Phase 2 Layout Components
 ### Status: COMPLETE
 ### What was done:
 - Created `date_range_picker()` reusable component:
  - Checkbox to enable/disable the filter
  - From/To date inputs using HTML5 date type
  - Disabled styling when filter is off (opacity reduced)
  - Uses design system tokens throughout
 - Created `searchable_dropdown()` reusable component:
  - Trigger button showing selection count ("All N items" or "X of Y selected")
  - Collapsible dropdown panel with search input
  - Select All / Clear buttons
  - Scrollable checkbox list with hover highlighting
  - Selected items highlighted with Pale Blue background
  - Uses `rx.foreach()` with `selected_items.contains(item)` pattern
 - Implemented full `filter_section()` component:
  - Card container with design system styling
  - Row 1: Two date range pickers (Initiated OFF, Last Seen ON by default)
  - Row 2: Three searchable dropdowns for Drugs, Indications, Directorates
  - Responsive flex-wrap layout for smaller screens
 - Added comprehensive state management to AppState:
  - Filter toggle states (initiated_filter_enabled, last_seen_filter_enabled)
  - Date value state (initiated_from/to_date, last_seen_from/to_date)
  - Dropdown visibility state (drug/indication/directorate_dropdown_open)
  - Selection state (selected_drugs, selected_indications, selected_directorates)
  - Search state (drug_search, indication_search, directorate_search)
  - Placeholder available options (will be populated from data in Phase 3)
  - Event handlers for all interactions (toggles, selections, search)
  - Computed vars for filtered options (@rx.var filtered_drugs, etc.)
  - Computed vars for selection text display
 - Fixed text_caption() conflict by manually specifying typography props when overriding color
 ### Validation results:
 - Tier 1 (Code):
  - `python -m py_compile pathways_app/app_v2.py` PASSED
  - `python -c "from pathways_app.app_v2 import app"` PASSED
  - Component type: filter_section() returns Box
 - Tier 2 (Visual): Deferred - requires modifying rxconfig to test app_v2
 - Tier 3 (Functional): State handlers verified via import; actual interaction testing in Phase 3
 ### Files changed:
 - Modified: pathways_app/app_v2.py (+544 lines - state, components, handlers)
 - Modified: IMPLEMENTATION_PLAN.md (marked 2.2 subtasks complete)
 ### Committed: b2d4afd "feat: implement filter section with date pickers and searchable dropdowns (Task 2.2)"
 ### Patterns discovered:
 - Don't use `**text_caption(), color=X` — helper already sets color. Instead, manually specify props.
 - `rx.checkbox(item, checked=selected_items.contains(item), ...)` works for multi-select in rx.foreach
 - When closing one dropdown, close others: `self.indication_dropdown_open = False` in toggle handlers
 - Computed vars with `@rx.var` must have return type annotation to work correctly
 - Use `rx.cond(is_open, dropdown_panel)` for conditional visibility of dropdown
 - Position absolute for dropdown panel, relative for container, z-index for layering
 ### Next iteration should:
 - Continue with Task 2.3: KPI Row
 - Implement `kpi_card()` component per design system:
  - Large mono number (32-48px), caption label below
  - Subtle shadow, optional Pale Blue tint
 - Implement `kpi_row()` with responsive grid
 - Initially show "Unique Patients" placeholder (actual data in Phase 3)
 - Consider adding more metrics: Drug count, Total cost, Match rate
 ### Blocked items:
 - Debounced filter handlers (300ms) deferred to Phase 3.3 — not blocked, just sequenced
 - Visual validation still blocked until rxconfig is updated
