Task 5.3 is the next incomplete task in Phase 5. +- Iteration 14 explicitly recommended this task. +- The header already had placeholder spans for record count and last updated — this task makes them useful. +### Status: COMPLETE +### What was done: +- Added `_format_relative_time(iso_timestamp)` helper to `dash_app/callbacks/filters.py`: + - Parses ISO timestamp and returns relative time: "just now", "15m ago", "3h ago", "yesterday", "4d ago", "1w ago", or "23 Dec 2025" for older dates + - Handles empty strings, invalid dates gracefully +- Added `total_patients` field to `load_initial_data()` in `src/data_processing/pathway_queries.py`: + - Queries root node (level 0) value from default filter (all_6mo, directory) as patient count + - Only runs when `total_records` is 0 (source_row_count empty in refresh log — known issue) + - Returns 11,118 patients for current data +- Updated `load_reference_data` callback to use both improvements: + - Record text: "11,118 patients" (comma-formatted, falls back to "Data loaded" if no data) + - Updated text: "14h ago" (relative time from last_updated ISO timestamp) + - Matches design reference in 01_nhs_classic.html: green dot + "{N} records" + "Last updated: 2h ago" +### Validation results: +- Tier 1 (Code): All imports pass, app starts, 7 callbacks registered +- Tier 1 (App starts): `from dash_app.app import app` — OK +- Tier 3 (Functional): + - Relative time formatting: tested 10 cases (just now, minutes, hours, yesterday, days, weeks, months, empty, invalid, actual value) — all correct + - Record text: "11,118 patients" — correct + - Updated text: "14h ago" — correct (refresh was at 2026-02-06T00:08:55) +### Files changed: +- `src/data_processing/pathway_queries.py` — Added: total_patients query from root node +- `dash_app/callbacks/filters.py` — Added: _format_relative_time helper, updated load_reference_data +- `IMPLEMENTATION_PLAN.md` — Task 5.3 marked [x] +### Committed: e877268 "feat: add data freshness indicator with relative time and patient count (Task 5.3)" +### Patterns discovered: +- `total_records` from `pathway_refresh_log.source_row_count` is always 0 for this project.

Sub-items: + 1. Remove `reflex` from `pyproject.toml` dependencies + 2. Move `pathways_app/` to `archive/` (don't delete — keep for reference) + 3. Delete `pathways_app/styles.py` and any Reflex-specific files + 4. Update `CLAUDE.md` to document the Dash app structure, new run command (`python run_dash.py`), callback architecture + 5. Run `python run_dash.py` — verify app starts cleanly + 6. Verify no Reflex imports in `dash_app/` + 7. Run `uv sync` after removing reflex dependency +- IMPORTANT: Read the completion criteria at bottom of IMPLEMENTATION_PLAN.md — all must be satisfied +- After 5.4, check if ALL tasks are [x] and output the COMPLETE signal ### Blocked items: - None
