CI / lint-and-test (pull_request) Has been cancelled
Details 
- Update dbt model references to use new schema naming (stg_toronto, int_toronto, mart_toronto)
- Refactor figure factories to use consistent column naming from new schema
- Update callbacks to work with refactored data structures
- Add centralized design tokens module for consistent styling
- Streamline CLAUDE.md documentation

Some checks failed
CI / lint-and-test (pull_request) Has been cancelled
Details 
- Create generate_schema_name macro to use custom schema names directly
- Update dbt_project.yml schemas: staging→stg_toronto, intermediate→int_toronto, marts→mart_toronto
- Add dbt/macros/toronto/ directory for future domain-specific macros
- Fix documentation drift in PROJECT_REFERENCE.md (load-data-only→load-toronto-only)
- Update DATABASE_SCHEMA.md with new schema names
- Update CLAUDE.md database schemas table
- Update adding-dashboard.md runbook with domain-scoped pattern

62d1a52eed refactor: multi-dashboard structural migration
Some checks failed
CI / lint-and-test (pull_request) Has been cancelled
Details 
- Rename dbt project from toronto_housing to portfolio
- Restructure dbt models into domain subdirectories:
  - shared/ for cross-domain dimensions (dim_time)
  - staging/toronto/, intermediate/toronto/, marts/toronto/
- Update SQLAlchemy models for raw_toronto schema
- Add explicit cross-schema FK relationships for FactRentals
- Namespace figure factories under figures/toronto/
- Namespace notebooks under notebooks/toronto/
- Update Makefile with domain-specific targets and env loading
- Update all documentation for multi-dashboard structure

This enables adding new dashboard projects (e.g., /football, /energy)
without structural conflicts or naming collisions.

193b9289b9 fix: Configure dbt to use local profiles.yml 
- Rename profiles.yml.example to profiles.yml (uses env vars, safe to commit)
- Add --profiles-dir flag to dbt commands in load_toronto_data.py
- Add --profiles-dir flag to dbt targets in Makefile

This fixes the "Path '~/.dbt' does not exist" error when running make load-data.

d0f32edba7 fix: Repair data pipeline with StatCan CMHC rental data 
- Add StatCan CMHC parser to fetch rental data from Statistics Canada API
- Create year spine (2014-2025) as time dimension driver instead of census
- Add CMA-level rental and income intermediate models
- Update mart_neighbourhood_overview to use rental years as base
- Fix neighbourhood_service queries to match dbt schema
- Add CMHC data loading to pipeline script

Data now flows correctly: 158 neighbourhoods × 12 years = 1,896 records
Rent data available 2019-2025, crime data 2014-2024

b6d210ec6b feat: Implement Phase 4 dbt model restructuring 
Create neighbourhood-centric dbt transformation layer:

Staging (5 models):
- stg_toronto__neighbourhoods - Neighbourhood dimension
- stg_toronto__census - Census demographics
- stg_toronto__crime - Crime statistics
- stg_toronto__amenities - Amenity counts
- stg_cmhc__zone_crosswalk - Zone-to-neighbourhood weights

Intermediate (5 models):
- int_neighbourhood__demographics - Combined census with quintiles
- int_neighbourhood__housing - Housing + affordability indicators
- int_neighbourhood__crime_summary - Aggregated crime with YoY
- int_neighbourhood__amenity_scores - Per-capita amenity metrics
- int_rentals__neighbourhood_allocated - CMHC via area weights

Marts (5 models):
- mart_neighbourhood_overview - Composite livability score
- mart_neighbourhood_housing - Affordability index
- mart_neighbourhood_safety - Crime rates per 100K
- mart_neighbourhood_demographics - Income/age indices
- mart_neighbourhood_amenities - Amenity index

Closes #60, #61, #62, #63

457bb49395 feat: add loaders and dbt models for Toronto housing data 
Sprint 4 implementation:

Loaders:
- base.py: Session management, bulk insert, upsert utilities
- dimensions.py: Load time, district, zone, neighbourhood, policy dimensions
- trreb.py: Load TRREB purchase data to fact_purchases

dbt Project:
- Project configuration (dbt_project.yml, packages.yml)
- Staging models for all fact and dimension tables
- Intermediate models with dimension enrichment
- Marts: purchase analysis, rental analysis, market summary

Closes #16
