These were left behind after the earlier XGBoost heat-wave predictor
cut (93f565b) and the move to empirical burn analysis for pricing.
Nothing in src/pipeline.py or src/api.py imports them; the eval tests
they ship with couldn't pass either (neural_pricer_dar.pt never
existed on disk, so test_neural_model_loads fails by construction).
Removed:
- src/prediction/heat_forecast.py (HeatWavePredictor)
- src/prediction/lstm_model.py (LSTM trainer + CITY_THRESHOLDS)
- src/pricing/neural_actuarial.py (neural pricer; replaced by burn analysis)
- src/notification/sender.py + __init__.py (notify step was cut in a
prior pipeline pass; no one imports this anymore)
- scripts/train_neural_pricer.py, train_on_era5.py, train_on_nasa_power.py,
train_lstm.py, backtest_pricing.py (all drove the dead paths)
- tests/eval_heat_predictor.py, eval_neural_pricer.py (evaluated dead code)
- models/heat_predictor_xgb.json, trigger_head_retrained.pt
- (untracked) models/heat_lstm.pt, lstm_norm.json,
scripts…
Replace neural actuarial model with GraphCast triggers + empirical burn analysis
The 30 hand-crafted pilot personas felt token — the DPI routing fabric
story works better at scale. New script
`scripts/populate_worker_population.py` generates 2000 enrollees
distributed proportionally across the 15 Dar neighborhoods by
worker_population_est. Deterministic (seed=42). Realistic Swahili
names from expanded pools, settlement-appropriate occupations
(informal: waste pickers / charcoal sellers / water sellers /
day laborers; commercial: market porters / stall vendors / hawkers;
mixed: boda-boda drivers / mama lishes / welders; formal: security
guards / drivers / housekeepers). Weighted mobile-money split
(M-Pesa 55 / Tigo 27 / Airtel 18), TASAF enrollment probabilities
per settlement type (40% informal down to 5% formal), ages 20-60,
years outdoor bounded by adult years.
Script already run — 2000 rows live in the workers table alongside
the original 30 hand-crafted personas (worker_id prefix P vs W).
Disbursements page: "Pilot enrollees" tab renamed to "Enrollees",
rewri…
Coverage polish + DPI-style worker pilot with Disbursements drill-down
Coverage page:
- Cost section now renders Annual program cost, Cost per worker, and
3-year total in matching 44px Source Serif blocks (previously the
Annual cost was a 56px custom headline and the other two were default
MetricCards, creating an awkward size asymmetry).
- "Where it lands" table rebuilt: dropped the "Total / worker" column
(redundant with fast cash + insurance per worker), added a "Total to
neighborhood" column showing aggregate $ flowing to each triggered
neighborhood this week (per_worker × enrolled_workers), added a
"Workers" column, and renamed the zone header to "Neighborhood".
Reads as: "Kinondoni → $138,600 this week to 7,700 workers".
DPI-style worker pilot (the climate-risk equivalent of Market Intel's
Lakshmi/Kumar/Meena and Weather AI's 2k DPI farmer registry):
- New `workers` table in Neon (src/database/schema.py) with
worker_id / name / name_swahili / nida_id / phone / zone_id /
occupation / age / years_outdoor / household_size / mobile_…
Pipeline was claiming to be adaptable but hardcoded Dar references sat
inside the "DO NOT CHANGE" files. A forker would hit an empty zones list,
a missing era5 file, and the weekly-review prompt would still say "for
Dar es Salaam". Now config.py is the only place that needs editing.
- config.py: add PRIMARY_CITY, PRIMARY_CITY_SLUG, slug_for() helper;
PRIMARY_CITY in ZONES runtime check so a bad edit fails fast
- src/pipeline.py: DAR_ZONES to ACTIVE_ZONES derived from PRIMARY_CITY;
ERA5 path and weekly-review prompt are now config-driven
- scripts/fetch_era5land.py (renamed from _dar): config-driven bbox and
filename via --city; rewrote extract_zone_data to extract_all_zones
(opens each NetCDF file once per month instead of once per zone, 15x
fewer opens for a 20-year fetch)
- scripts/train_neural_pricer.py: fix buggy "Dar es Salaam" to "dar" slug
that would have broken ERA5 file resolution for any fork; raise WBGT
fallback 30.0 to 35.0 for tropical defaults
- tests/eval_…
- Fix UHI_RANGES inconsistency: neural_actuarial.py now imports from
uhi_model.py instead of defining its own (mixed was 1.5 vs 1.0)
- Fix healer.py crash: replaced flood-era attributes (flood_susceptibility,
drainage_quality, rainy_seasons) with heat-era equivalents
- Fix N+1 linear scan in /api/calibrate: build indices_by_id dict upfront
- Remove redundant WBGT recomputation in build_training_samples
- Remove unused UHICorrector() instantiation in build_training_samples
- Remove dead imports: math, asdict, HEAT_THRESHOLDS, PAYOUT_PER_EVENT_USD,
DailyReading from pipeline.py
- Fix train_neural_pricer.py bug: .items() → removed dead variable
- Update eval test for 30 zones (was hardcoded to 20)

Expand Dar es Salaam to 15 zones, retrain neural pricer on ERA5-Land
Added 10 new zones: Manzese, Tandale, Buguruni, Vingunguti, Mbagala
(informal), Kariakoo (commercial), Ubungo, Magomeni (mixed), Mikocheni,
Masaki (formal). Each with real coordinates, population, exposure data.
Neural model retrained on 15,450 samples (15 zones × 20 years ERA5-Land).
Rank correlation 0.929. Informal settlements priced 2.6x higher than
formal neighborhoods ($3,660 vs $1,394/worker/year).

Retrain neural actuarial model on ERA5-Land 9km data (20 years)
ERA5-Land provides 9km resolution vs NASA POWER's 55km — resolves
2 distinct grid cells across Dar es Salaam (north vs south).
20 years (2005-2024) of daily data: temperature, dewpoint, wind,
solar radiation, precipitation.
Results after retraining:
- Rank correlation: 0.985 (near-perfect zone ordering)
- Jangwani (informal) $8,538 vs Kinondoni (formal) $1,550 — 5.5x spread
- Model correctly prices UHI-amplified zones much higher

Redesign Program Designer as Coverage Recommendation page
The neural model RECOMMENDS the budget — the page no longer asks
"what's your budget?" It leads with: "$X needed this week to protect
Y workers across Z zones at elevated risk."
New /api/coverage-recommendation endpoint. Zone cards ranked by urgency.
Cost decomposition bar (worker payouts vs admin vs reserves). Neural
model insight per zone. Tour updated to tell the neural model story.

Add neural actuarial pricing engine trained on real Dar es Salaam data
Three-headed temporal neural model (LSTM encoder + Neural EVT hazard +
WHO/ILO vulnerability + CANN pricing) trained on 20 years of NASA POWER
daily climate data for 5 Dar es Salaam zones.
Key results:
- Jangwani (informal, +4.5C UHI) priced highest at $5,305/worker/yr
- Kinondoni (formal, +1C UHI) priced lowest at $2,776/worker/yr
- Basis risk learned: informal 0.53 > mixed 0.43 > formal 0.30
- Neural correction (delta_NN) is modest: -0.9% to -4.0% vs GLM baseline
- Rank correlation 0.914 on held-out validation data
Architecture: ~230K params, 910 KB saved model. CANN skip connection
means delta_NN=0 reproduces the existing ActuarialPricer formula exactly.
Falls back to GLM if model not found.
Based on: Chen et al. (Management Science 2024), EQRN (Pasche & Engelke
2024), CANN (Richman & Wuthrich), ISO 7243 occupational heat stress.

Retrain models on real NASA POWER data, wire pipeline to Neon, enable Claude
Models:
- LSTM retrained on 727 days of real NASA POWER data (20 zones, val AUROC 0.92)
- XGBoost retrained on same data (val AUROC 0.86)
- UHI model kept on literature-calibrated synthetic (no ground truth available)
Database:
- Pipeline writes to Neon after each step (daily_readings, healed_readings,
heat_indices, predictions, trigger_events, pipeline_runs)
- All DB writes wrapped in try/except — pipeline never crashes on DB errors
- run_pipeline.py updated: loads .env, uses HeatRiskPipeline, async DB init
Claude:
- Healing and explanation enabled by default (use_claude_healer=True)
- Activates when ANTHROPIC_API_KEY is set (HF Spaces secrets)
- Graceful fallback to rule-based when key is missing
Also: dotenv loading in api.py, zones seeded to Neon on startup,
training script at scripts/train_on_nasa_power.py
