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.

CSV is read with dtype=str so all values arrive as strings. Declaring
LA (code) and EstablishmentNumber as IntegerType caused schema
validation failures in target-postgres. Use StringType for all columns
except URN (which is explicitly cast to int for the primary key).
Type casting happens in dbt staging models.

Meltano 4.x requires an environment to be specified. Set production as
the default. Also remove the deprecated 'version: 2' field.

The meltanolabs target-postgres variant expects 'database' as the
config key, not 'dbname' (which was the pipelinewise variant's key).

The `catalog` capability forced Meltano to run --discover and generate
a catalog file (tap.properties.json) before each extraction. This fails
because our Singer SDK taps emit schemas inline and don't need external
catalog files. Removing the capability makes Meltano invoke taps
directly without catalog generation.
Also switch from deprecated `meltano elt` to `meltano run` for
Meltano 4.x compatibility.

Meltano elt requires catalog files (tap.properties.json) to exist.
These are generated by `meltano install` which discovers tap schemas
and installs the target-postgres loader. Without this step, `meltano
elt` fails with "catalog file is missing".

Port critical patterns from the working integrator into Singer taps:
- GIAS: add 404 fallback to yesterday's date, increase timeout to 300s,
use latin-1 encoding, use dated URL for links (static URL returns 500)
- FBIT: add GIAS date fallback, increase timeout, fix encoding to latin-1
- IDACI: use dated GIAS URL with fallback instead of undated static URL,
fix encoding to latin-1, increase timeout to 300s
- Ofsted: try utf-8-sig then fall back to latin-1 encoding

- Add AIRFLOW__CORE__DAGS_FOLDER env var in Dockerfile so it's always set
- Run `airflow dags reserialize` after `db migrate` in init container so
DAGs appear immediately without waiting for scheduler scan interval

- MELTANO_BIN/DBT_BIN pointed to .venv/bin/ but Dockerfile installs globally
- Add try/except for BashOperator import to handle both Airflow 3 provider
path and legacy path, preventing silent DAG import failures

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

Airflow 3 replaced `airflow webserver` with `airflow api-server` and
removed the `airflow users` CLI. Auth is now via SimpleAuthManager
configured through AIRFLOW__CORE__SIMPLE_AUTH_MANAGER_USERS env var.
