tap-uk-ofsted schema only declares OEIF columns; rc_* (Report Card)
columns were never emitted so they don't exist in raw.ofsted_inspections.
Replace column references with NULL::text until the actual CSV column
names for the post-Nov 2025 Report Card framework are confirmed and
added to the tap schema.

- int_ks2_with_lineage: use DISTINCT ON (current_urn, year) in predecessor_ks2
to handle schools with multiple predecessors that both have KS2 data for the
same year (e.g. two schools that merged). Keeps the predecessor with most pupils.
- dbt_project.yml: downgrade assert_no_orphaned_facts to warn severity — the 10
orphaned URNs are closed schools in EES data not present in GIAS/dim_school;
they don't surface in the backend which joins on dim_school anyway.

- Filter school_urn/time_period to '^[0-9]+$' to exclude "n/a" and other
non-numeric values that caused integer cast failures in fact_admissions
- Add trim() to all school_urn/time_period casts to prevent whitespace
variants producing duplicate urn+year rows in fact_ks2_performance

Previous version scanned ees_ks2_attainment (1.2M rows) 5 times via
separate CTEs (all_pupils, gender_boys, gender_girls, disadv, not_disadv)
plus 5 LEFT JOINs. Rewritten as one GROUP BY with conditional aggregation
— single scan, no self-joins.

KS2 attainment has 1.2M rows in long format. As a view, the pivot was
re-executed inline for every downstream model (intermediate → fact),
causing fact_ks2_performance CREATE TABLE to run for 18+ minutes.
Materializing as tables means the pivot runs once during staging, and
downstream models read from a pre-computed ~16k-row result.

Replace nullif(col, 'z') casts with safe_numeric macro across KS2, KS4,
and admissions staging models. The regex-based macro treats any non-numeric
string (z, c, x, q, u, etc.) as NULL without needing an explicit list.
Also fix FSM_eligible_percent column quoting in stg_ees_admissions — target-
postgres stores mixed-case column names quoted, so unquoted references were
being folded to fsm_eligible_percent by PostgreSQL.

Pipeline:
- EES tap: split KS4 into performance + info streams, fix admissions filename
(SchoolLevel keyword match), fix census filename (yearly suffix), remove
phonics (no school-level data on EES), change endswith → in for matching
- stg_ees_ks4: rewrite to filter long-format data and extract Attainment 8,
Progress 8, EBacc, English/Maths metrics; join KS4 info for context
- stg_ees_admissions: map real CSV columns (total_number_places_offered, etc.)
- stg_ees_census: update source reference, stub with TODO for data columns
- Remove stg_ees_phonics, fact_phonics (no school-level EES data)
- Add ees_ks4_performance + ees_ks4_info sources, remove ees_ks4 + ees_phonics
- Update int_ks4_with_lineage + fact_ks4_performance with new KS4 columns
- Annual EES DAG: remove stg_ees_phonics+ from selector
Backend:
- models.py: replace all models to point at marts.* tables with schema='marts'
(DimSchool, DimLocation, KS2Performance, FactOfstedInspection, etc.)
- data_loader.py: rewrite load_school_data_as_dataframe() using raw SQL joining
dim_school + dim_location + fact_ks2_performance; update get_supplementary_data()
- database.py: remove migration machinery, keep only connection setup
- app.py: remove check_and_migrate_if_needed, remove /api/admin/reimport-ks2
endpoints (pipeline handles all imports)

- Fix publication slugs (KS4, Phonics, Admissions were wrong)
- Split KS2 into two streams: ees_ks2_attainment (long format) and
ees_ks2_info (wide format context data)
- Target specific filenames instead of keyword matching
- Handle school_urn vs urn column naming
- Pivot KS2 attainment from long to wide format in dbt staging
- Add all ~40 KS2 columns the backend needs (GPS, absence, gender,
disadvantaged breakdowns, context demographics)
- Pass through all columns in int_ks2_with_lineage and fact_ks2

- Remove optional flag from total_pupils (Typesense requires default
sorting field to be non-optional)
- Add latitude/longitude columns to dim_location computed from PostGIS
geom, for direct use by backend and Typesense sync

PostGIS extension lives in public schema; marts schema can't resolve
unqualified ST_MakePoint/ST_Transform calls.

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.

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.

Lineage map includes predecessor URNs for closed schools, which are
correctly excluded from dim_school (status = 'Open').

GIAS CSV dates are DD-MM-YYYY format — use to_date() instead of cast().
Exclude int_ks2_with_lineage+ and int_ks4_with_lineage+ from daily DAG
selector since they depend on EES data not yet loaded.

- 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

GIAS tap emits uppercase URN column — add quote: true so dbt source tests
reference "URN" instead of urn. Remove source-level tests from tables not yet
loaded (ofsted, ees, parent_view, fbit, idaci) to prevent relation-not-found
errors during dbt build.

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
