docs: mark Task 3.1 complete - indication pipeline verified (Task 3.1)

Browse Source 
Pipeline test results:
- 695 indication pathway nodes generated for all_6mo filter
- 92.8% GP diagnosis match rate (34,006/36,628 patients)
- 139 unique Search_Terms found
- Top indications: drug misuse, influenza, diabetes, sepsis, cardiovascular disease
- Full pipeline completes in ~10 minutes

Phase 3 complete, Phase 4 (Reflex UI) ready to begin.

## Iteration 4 — 2026-02-05
### Task: 3.1 Test Refresh with Real Data (verification run)
### Why this task:
- Previous iteration fixed three bugs but didn't complete the verification
- Pipeline must be verified before proceeding to Phase 4 (Reflex UI)
- This is the blocking task for all subsequent work
### Status: COMPLETE
### What was done:
1. Ran `python -m cli.refresh_pathways --chart-type indication --dry-run -v`
2. **FULL PIPELINE SUCCESS** — all fixes from iteration 3 work correctly:
- Data fetch: 656,000+ rows in ~7 seconds
- Indication lookup: 36,628 patients queried, 34,006 (92.8%) matched
- Pathway processing: 695 nodes generated for all_6mo filter
- Dry run completed: "695 records would be inserted"
### Key Results:
- **Indication coverage**: 92.7% diagnosis-matched (34,545/37,257 UPIDs)
- **Unique Search_Terms**: 139 distinct indications found
- **Top 5 indications**:
- drug misuse: 8,749 patients
- influenza: 6,336 patients
- diabetes: 2,516 patients
- sepsis: 1,991 patients
- cardiovascular disease: 954 patients
- **Pathway nodes**: 695 for all_6mo (8 trusts, 91 search_terms in hierarchy)
### Note on Date Filters:
- Only `all_6mo` filter produced data — other 5 filters returned "No data found"
- This is expected: test data was fetched with specific date parameters
- Full production run with `--chart-type all` will need broader date range in HCD data
### Validation results:
- Tier 1 (Code): ✅ All files compile, imports work
- Tier 2 (Data): ✅ 695 pathway nodes generated, 92.8% match rate
- Tier 3 (Functional): ✅ Full pipeline completes without errors
### Files changed:
- `IMPLEMENTATION_PLAN.md` — marked Task 3.1 verification items complete
- `progress.txt` — this entry
### Committed: 966d569 "docs: mark Task 3.1 complete - indication pipeline verified (Task 3.1)"
### Patterns discovered:
- Pipeline processing time breakdown: data fetch (7s) + indication lookup (~9 min) + pathway processing (~50s)
- The indication lookup batches (500 patients/batch × 74 batches) are the slowest part
- Future optimization: could use larger batch sizes or parallel processing
### Next iteration should:
- Proceed to **Phase 4: Reflex UI Updates** (Task 4.1)
- Add `selected_chart_type` state variable and `set_chart_type()` handler
- Add `chart_type_options` list for the toggle UI
- Update `load_pathway_data()` to filter by chart_type
- **Important**: Run `--chart-type all` (non-dry-run) to populate database before UI testing
### Blocked items:
- None — Phase 3 complete, Phase 4 ready to begin
