tudorandClaude Opus 4.6	b7cc01f26f	fix(dbt): schema-qualify PostGIS functions in dim_location ... PostGIS extension lives in public schema; marts schema can't resolve unqualified ST_MakePoint/ST_Transform calls. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 21:45:03 +00:00
tudorandClaude Opus 4.6	28ba2fd0a6	fix(dbt): cast easting/northing to double precision for ST_MakePoint ... Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 21:29:16 +00:00
tudorandClaude Opus 4.6	54df58746e	feat(pipeline): use GIAS easting/northing for all geocoding, drop postcode step ... GIAS grid references are the actual school location — far more accurate than postcode centroids. Remove geocode_postcodes.py from the daily DAG and the postcode-not-null filter from dim_location.

tudorandClaude Opus 4.6	d3e655abdb	fix(dbt): compute geom from easting/northing in dim_location ... Convert GIAS British National Grid coordinates (EPSG:27700) to WGS84 (EPSG:4326) directly in the dbt model. The geocode script backfills schools missing easting/northing via Postcodes.io.

tudorandClaude Opus 4.6	d25e333826	fix(dbt): remove invalid relationship test on map_school_lineage ... Lineage map includes predecessor URNs for closed schools, which are correctly excluded from dim_school (status = 'Open').

tudorandClaude Opus 4.6	e7b1ab9f37	fix(pipeline): expand GIAS schema, handle empty strings, scope DAG selectors ... - Declare all 34 columns needed by dbt in GIAS tap schema (target-postgres only persists columns present in the Singer schema message) - Use nullif() for empty-string-to-integer/date casts in staging models - Scope daily DAG dbt build to GIAS models only (stg_gias_establishments+ stg_gias_links+) to avoid errors on unloaded sources - Scope annual EES DAG similarly; remove redundant dbt test steps - Make dim_school gracefully handle missing int_ofsted_latest table Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 20:43:24 +00:00
tudorandClaude Opus 4.6	97d975114a	feat(pipeline): implement parent-view, fbit, idaci Singer taps + align staging/mart models ... Port extraction logic from integrator scripts into Singer SDK taps: - tap-uk-parent-view: scrapes Ofsted open data portal, parses survey responses (14 questions) - tap-uk-fbit: queries FBIT API per-URN with rate limiting, computes per-pupil spend - tap-uk-idaci: downloads IoD2019 XLSX, batch-resolves postcodes→LSOAs via postcodes.io Update dbt models to match actual tap output schemas: - stg_idaci now includes URN (tap does the postcode→LSOA→school join) - stg_parent_view expanded from 8 to 13 question columns - fact_deprivation simplified (no longer needs postcode→LSOA join in dbt) - fact_parent_view expanded to include all 13 question metrics Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 10:38:07 +00:00
tudorandClaude Opus 4.6	8f02b5125e	feat(pipeline): add Meltano + dbt + Airflow ELT pipeline scaffold ... Replaces the hand-rolled integrator with a production-grade ELT pipeline using Meltano (Singer taps), dbt Core (medallion architecture), and Apache Airflow (orchestration). Adds Typesense for search and PostGIS for geospatial queries. - 6 custom Singer taps (GIAS, EES, Ofsted, Parent View, FBIT, IDACI) - dbt project: 12 staging, 5 intermediate, 12 mart models - 3 Airflow DAGs (daily/monthly/annual schedules) - Typesense sync + batch geocoding scripts - docker-compose: add Airflow, Typesense; upgrade to PostGIS - Portainer stack definition matching live deployment topology Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 08:37:53 +00:00
