Pure-domain select_comparables: property type is an always-hard filter; built
form and known Landlord Overrides (e.g. solid brick) are conditioning filters on
the filter-then-relax ladder — applied while >= minimum_cohort survive, relaxed
otherwise (the mixed-street border case degrades gracefully). PredictionTarget
(known inputs) + Comparable (epc + register metadata) + ComparableProperties
(selected cohort). Weighting (recency x similarity) follows in the synthesis slice.

Builds the frozen validation corpus: samples postcodes from the register, then
caches each postcode's full cohort of raw cert payloads (the shape
from_api_response consumes), grouped by postcode, resumably. Reads the token
from backend/.env; cache dir /tmp/epc_prediction_corpus (EPC_PREDICTION_CORPUS
override). IO plumbing, not test-driven. Pairs with the leave-one-out harness.

Promote RdSAP-Schema-17.0 into SUPPORTED so all 1000 corpus certs are held to
the strict parse+map guard. Drop the now-redundant cert[0] tracer (subsumed by
the parametrised bucket); keep the reduced-field synthesis behavioural test.

Add the 17.0 synthesis seam over the shared _synthesise_reduced_field_windows
core (inherited 20.0.0 coefficients, ND glazing -> DG-modal default 2, per
ADR-0028). 17.0 glazed_type codes (1-4,7) are a subset of the verified 1-8
space. The 10 rich certs use lodged window_area directly; the windowless 990
synthesise a 4-way N/E/S/W split.

Dispatch RdSAP-Schema-17.0 through from_api_response, parse-fix the schema
(data-driven required->optional, validated against the 1000-cert 17.0 corpus
per ADR-0028 — incl. SapHeating.cylinder_insulation_type and the
has_hot_water_cylinder / has_fixed_air_conditioning / has_heated_separate_
conservatory flags), and port the defensive mapper reads (dwelling_type
str/dict/number, photovoltaic_supply guard, sap_floor_dimensions guard). All
1000 corpus certs now parse and map.

Reusable per-schema profiler: glazed_area band mix, Validation Cohort size,
observed-vs-predicted band glazing/floor ratio, and the ND/str sentinels that
drive schema widening. Regenerates the ADR-0028 transfer-check table from any
harvested corpus.

Promote RdSAP-Schema-19.0 into SUPPORTED so all 1000 corpus certs are held to

Add the 19.0 synthesis seam over the shared _synthesise_reduced_field_windows
core (inherited 20.0.0 coefficients, ND glazing -> DG-modal default 2, per
ADR-0028). 19.0 glazed_type codes (1-4,6,7) are a subset of the verified 1-8

synthesise a 4-way N/E/S/W split.

Orchestrator runs recommend_secondary_heating_removal; report._triggers_for
explains it via the lodged secondary_heating_type; harness catalogue + ARA seed
price it. Re-pins the golden/integration plans it shifts: it is a cheap (\£250)
SAP lever, so on gas-main certs lodging an electric secondary (691) it displaces
the \£12k ASHP (0330, 0036) or joins the all-beneficial-measures package (000490,
where its marginal SAP is 0 under the category-4 ASHP but the heater is still
physically removed). Consistent with the optimiser's existing kitchen-sink
package behaviour.

Two cascade tests on the worksheet-pinned 001431 build_epc() (the user's
before/after Summary PDFs trip the documented 001431 window-extraction bug, so
the repo's sanctioned 001431 baseline is used instead):
- electric-storage main (code 402) + secondary 691: removal reproduces the
secondary-removed cert at delta 0 — RdSAP §A.2.2 re-forces a default secondary,
matching the user's F35→F35 example;
- gas combi main (code 104) + secondary 691: removal strictly raises SAP
(74.22→77.61) — the Table 11 fraction reallocates to the cheaper main.

Records the four load-bearing design decisions from the grill-with-docs session:
standalone co-selectable rec; eligibility = lodged-only (no effectiveness gate,
electric-storage §A.2.2 no-op is the Optimiser's call); dedicated clearing
SecondaryHeatingOverlay; flat per-dwelling cost (a lodged secondary is fixed per
RdSAP, so a real decommission job, not room-scaled).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Flat per-dwelling decommission price (sample_catalogue \£250) + 0.25 contingency
(covers unknown heater count / hard-wired-vs-plugged / repaint extent). The JSON
repo joins the contingency from config, proven by the new repo test. No composite
Products machinery — a lodged secondary is one roughly-fixed job, not room-scaled.

recommend_secondary_heating_removal offers one standalone Option that clears the
lodged secondary system. Eligibility is purely physical (offer iff
sap_heating.secondary_heating_type is set) — no effectiveness gate, since a
lodged secondary is a fixed emitter per RdSAP (portables are ignored), and the
electric-storage §A.2.2 no-op is the Optimiser's call (ADR-0028 decisions 1-2).
Priced at a flat per-dwelling decommission cost, not room-scaled.

ADR-0028's deferred extraction, triggered by 17.1 as the second instance: the
inherited 20.0.0 coefficients (0.148 + band multipliers + 4-way split) now live
in one `_synthesise_reduced_field_windows` core. The 20.0.0 / 18.0 / 17.1 seams
keep their own names (so each can diverge) but collapse to glazing-type
resolution (cascade + that spec's ND handling) plus a call to the core.

Rich certs (14/1000) use lodged window_area; the windowless majority synthesise
glazing from the glazed_area band via _synthesise_17_1_sap_windows (own seam,
inherited 20.0.0 coefficients); lighting/ventilation/hot-water mirror 18.0.

The first overlay surface that sets fields to *absent* rather than to a
target state: _fold_secondary_heating clears sap_heating.secondary_heating_type
+ secondary_fuel_type, so the calculator's Table 11 secondary-fraction split
(SAP 10.2 §9a) routes 100% of space heating to the main. On an electric-storage
main RdSAP §A.2.2 re-forces a default secondary, making removal a no-op there —
left to the Optimiser to de-select (ADR-0028 decisions 2-3).

Schema-fix delivered in the prior slice; this promotes the 1000-cert corpus

Documents the inherit-and-validate decision for 18.0: reuse 20.0.0's 0.148 +
band multipliers (the corpus can't self-fit — 958/1000 band-1 with no measured
band-1 windows), validated against 18.0's own band-4 rich certs (0.223 obs vs
0.148 x 1.51 pred). References ADR-0027 one-way (keeps the accepted ADR immutable).

Behaviour delivered by the band-multiplier dict in the prior slice; this pins
