One-time script (dry-run default, --apply in a transaction, idempotent) mapping a
flat roof's stated depth (flat: Nmm) onto the nearest Table 16 rung member so the
overlay scores it by thickness, not the age-band default. Updates property_overrides
(TEXT) immediately; the roof_type pgEnum cache writes are deferred until the FE adds
the FLAT_*MM members. Dry-run against the audited DB reports 102 rows, deferring
Flat 50/100/150 mm.

One-time script (dry-run default, --apply in a transaction, idempotent) that
NULLs the four lodged_* columns on every predicted-source baseline row — a
predicted EPC exists and no lodged one does — leaving Effective, the bill block,
and rebaseline_reason intact. Dry-run against the audited DB reports 12,236 rows.
Must run after the FE-owned Drizzle ALTER ... DROP NOT NULL lands.

Deterministic catalogue remap (no LLM) that re-resolves the stored archetype for
the canonical RdSAP heating descriptions the under-populated taxonomy
mis-classified. Dry-run by default; --apply writes inside a transaction;
idempotent. Updates property_overrides.override_value (TEXT — what the modelling
reads, the actual band-G fix: 3,028 rows incl. 2,210 community boilers + 770
panel/convector room heaters). Cache (the Drizzle-owned main_heating_system
pgEnum) updates are deferred per-value until the FE-repo enum migration adds the
new archetypes — surfaced explicitly by the script.
