## Iteration 43 — 2026-02-06
### Task: 10.11 — Final integration + documentation
### Why this task:
- This is the ONLY remaining task — all others are marked [x]
- Task 10.10 (CSS cleanup + polish) was completed in iteration 42
- Progress.txt from iteration 42 explicitly recommended Task 10.11 as the FINAL task
### Status: COMPLETE
### What was done:
- **Programmatic verification of Patient Pathways view**:
- Reference data loads: 42 drugs, 14 directorates, 32 indications, 7 trusts
- Directory mode (all_6mo): 293 nodes, 11,118 patients, 39 drugs, ~£130.6M
- Indication mode (all_6mo): 438 nodes, 11,252 patients
- Icicle figure renders: 1 trace, type=icicle
- Sankey figure renders: 2 drug transitions, 1 trace
- Drug filter (ADALIMUMAB): 91 nodes, levels [0,1,2,3,4,5] — hierarchy intact
- Trust filter (Cambridge): 15 nodes, levels [0,1,2,3,4] — hierarchy intact
- **Programmatic verification of Trust Comparison view**:
- Trust Market Share (RHEUMATOLOGY): 42 rows, 6 trusts, 17 drugs
- Trust Cost Waterfall: 6 rows (one per trust)
- Trust Dosing: 40 rows
- Trust Heatmap: 6 trusts × 17 drugs
- Trust Durations: 40 rows
- Cost Effectiveness (RHEUMATOLOGY): 38 pathway rows
- Indication mode (asthma): 3 rows, 2 trusts, 2 drugs
- All 3 trust-specific figure builders render correctly
- **Callback/layout verification**:
- 20 callbacks registered (correct)
- 2 sidebar nav items: Patient Pathways, Trust Comparison
- 2 chart tabs: Icicle, Sankey
- 4 dcc.Store components: app-state, chart-data, reference-data, active-tab
- All 6 date filter IDs return data (all_6mo through 2yr_12mo)
- **Both chart types verified**: directory and indication modes work for both views
- **CLAUDE.md updated** with two-view architecture:
- Package structure updated (removed kpi_row.py, drawer.py; added modals.py, sub_header.py, trust_comparison.py, navigation.py, trust_comparison callbacks)
- State management updated to 4 stores with active_view and selected_comparison_directorate
- Callback chain updated with two-view flow diagram
- Key components updated (header fraction KPIs, 2-item sidebar, sub-header, filter bar, modals, trust comparison)
- Output section updated to describe two-view architecture
- Added trust-comparison visualization and query functions
- **All Phase 10 completion criteria marked [x]** in IMPLEMENTATION_PLAN.md
- **All tasks in IMPLEMENTATION_PLAN.md are [x]** — no remaining [ ], [~], or [B] items
### Validation results:
- Tier 1 (Code): `from dash_app.app import app` — OK, 20 callbacks
- Tier 1 (App starts): `python run_dash.py` — "Dash is running on http://127.0.0.1:8050/" — no errors
- Tier 3 (Functional): All data queries verified programmatically for both views, both chart types, drug/trust filters
### Files changed:
- `CLAUDE.md` — Updated with two-view architecture
- `IMPLEMENTATION_PLAN.md` — Task 10.11 and Phase 10 completion criteria marked [x]
### Committed: [pending]
### Patterns discovered:
- Programmatic verification (running queries and figure builders via `python -c`) is more reliable than manual browser testing for an amnesiac loop
- The final integration task is primarily verification + documentation — no code changes needed when previous iterations were thorough
### Next iteration should:
- N/A — ALL TASKS COMPLETE. The project is finished.
### Blocked items:
- None
