This (a) fixes a real bug — current mapper raw-passes the code, so the calculator mis-reads code 1 "double pre-2002" as single (62 certs); (b) needs no extension despite the cascade only remapping 1→2, because g⊥ comes from the per-window `window_transmission_details.solar_transmittance` (lodged for 687, Table-24-synthesized for 313) — so `glazing_type` only feeds g_L daylight, where the cascade is correct for every code present (code-5 single never appears; secondary g_L=0.80 ✓). `ND` is a string → calculator defaults g⊥ to 0.76 (double) naturally. + +**Non-window gaps — spec resolutions found (RdSAP10 tables), most likely already in `sap10_calculator`; verify which the calculator applies vs. the mapper must supply:** +- Hot-water demand (bath/shower counts): RESOLVED → derive from `instantaneous_wwhrs` room counts.

Calculator reads `sap_heating.number_baths`/`mixer_shower_count`/`electric_shower_count` (modal-default 1 bath/1 mixer/0 electric when None — `cert_to_inputs.py:4613-4660`). Present in 1000/1000; **496/1000 have ≠1 bath**, so modal default systematically under-counts HW demand for multi-bath homes.

Make it `@dataclass(kw_only=True)` + data-driven required→optional (any field + present in <100% of the corpus gets a default; `[]` for lists, `None` otherwise) → all certs parse. +3. **Synthesise the measured fields** the reduced schema only records categorically: + windows (`glazed_area` band × floor area, 4-way N/E/S/W split), lighting LEL, hot-water bath/mixer + counts, ventilation/chimneys/sheltered-sides, glazing cascade. +4. **Leave calculator defaults to the calculator** — `cert_to_inputs` is the RdSAP Table-5 expansion + engine; the mapper supplies raw reduced data only. +5. **Wire dispatch + flip a strict guard** — add the `schema_type` branch to + `from_api_response`, promote the corpus into the strict parse+map bucket in + `infrastructure/epc_client/tests/test_mapper_corpus.py`. +6. **Record every synthesis assumption in code comments + test names** (Validation-Cohort rule: no + same-spec ground truth). + +## Ground truth about the targets (verified 2026-06-10) + +| Spec | Schema module | Mapper method | Dispatched? | Corpus? | Notes | +|------|---------------|---------------|-------------|---------|-------| +| 21.0.1 | ✅ | `from_rdsap_schema_21_0_1` | ✅ | ✅ 1000 | reference (rich, measured) | +| 21.0.0 | ✅ | `from_rdsap_schema_21_0_0` | ✅ | ❌ | dispatched but unguarded | +| **20.0.0** | ✅ | `from_rdsap_schema_20_0_0` | ✅ | ✅ 1000 | **DONE — the template** | +| **19.0** | ✅ | `from_rdsap_schema_19_0` | ❌ | ❌ | orphaned; `sap_windows=[]` hardcoded | +| **18.0** | ✅ | `from_rdsap_schema_18_0` | ❌ | ❌ | orphaned | +| **17.1** | ✅ | `from_rdsap_schema_17_1` | ❌ | ❌ | orphaned | +| **17.0** | ✅ | `from_rdsap_schema_17_0` | ❌ | ❌ | orphaned | + +- 19.0 confirmed same reduced-field shape as 20.0.0: `glazed_area: int` band + `multiple_glazing_type: + int`, and the mapper currently hardcodes `sap_windows=[]` — i.e. the exact windowless-corruption bug + that 20.0.0's synthesis fixed. 18.0/17.1/17.0 are almost certainly the same family. +- The 17–19 mapper methods **exist** but are unreachable: `from_api_response` only branches 21.0.1 / + 21.0.0 / 20.0.0; everything else hits `raise ValueError(f"Unsupported EPC schema")`. +- **Corpora are harvestable.** `downloads/README.txt` schema-by-year: + `2020 → RdSAP-Schema-19.0 (1632)`, `2021–2024 → 20.0.0`, `2025–2026 → 21.0.1`. Older RdSAP (17.x/18.0) + live in the 2012–2019 dumps (all present locally). `SAP-Schema-1x` (full/design SAP) and `CEPC-*` + (commercial) are different families with no RdSAP mapper. + +--- + +## Decision tree to grill (each has a recommended answer) + +### Q1 (ROOT) — Target set and order. What are we generalising to, and in what order? +**Recommend:** the **pre-SAP10 RdSAP family only**, one spec at a time, **19.0 first** (dominant in the +2020 dump, closest sibling to 20.0.0, mapper already stubbed), then 18.0 → 17.1 → 17.0 as their dumps +confirm volume. **Exclude** `SAP-Schema-1x` (full/design SAP — new-build, not reduced; a separate +mapper family and ADR) and `CEPC-*` (non-domestic). **Carve out** 21.0.0 as a quick win: it's already +dispatched, it just needs a harvested corpus to join the strict guard. +*Sub-question:* do we batch all four 17–19 in one branch sweep, or land 19.0 fully (corpus → schema → +synthesis → dispatch → guard) before starting 18.0? Recommend: **land 19.0 end-to-end first** — it +either confirms the playbook transfers cleanly (then 18.0/17.x are fast) or surfaces drift early. + +### Q2 — Coefficient reuse vs re-fit (the load-bearing, ADR-worthy one). +20.0.0's glazing synthesis uses `0.148 × TFA × band_multiplier`, fit from the **21.0.1** corpus's +glazing/floor ratio. For 19.0/18.0/17.x: reuse the same coefficients, or re-fit per spec? +**DIRECTION (user, 2026-06-10): re-work the coefficients from each new corpus's own data — do not +inherit the 21.0.1 fit by default.** Treat `0.148` + the band multipliers as a *starting hypothesis* to +confirm or replace against what the new corpus actually shows, per spec. The empirical numbers lead; we +only keep the 20.0.0 values if the new corpus reproduces them. + +**The constraint this hits (must resolve while grilling):** a reduced schema does **not** measure +per-window area (that's the whole reason synthesis exists), so a 19.0/18.0/17.x corpus *cannot +self-fit the glazing/floor ratio* — there's no measured glazing column in it to regress on. So +"work it out from the new corpus" splits into two parts: +- **What the reduced corpus *can* give us directly** → re-derive per spec: the `glazed_area` band + *distribution* (how many Normal/More/Less), `total_floor_area` distribution, and whether the band + codes/semantics match 20.0.0. This validates (or breaks) the band-multiplier assumption empirically. +- **The base ratio itself (the `0.148`)** → needs a *measured* reference from the same stock/era. + Options to grill: (a) use the contemporaneous measured corpus if one exists for that year (e.g. a + rich-window spec lodged alongside), (b) fit from the handful of rich certs the reduced corpus *does* + carry (20.0.0 had 7/1000 with lodged `sap_windows` — check the count per spec), or (c) fall back to + the 21.0.1 fit *only* if (a)/(b) yield too little signal, and say so explicitly. + +This moves every rebaselined score for the spec, so the per-spec fit + its evidence wants an ADR +(extends ADR-0027). Record the derivation (corpus, sample size, quartiles) the same way 20.0.0 did. + +### Q3 — Code-space drift across versions. +Do 17–19 use the same integer code spaces as 20.0.0 (glazing_type, built_form, orientation, fuel, +heat-emitter, party-wall, roof/floor construction)? 20.0.0's codes turned out **identical** to 21.0.1's, +so we routed through the existing cascades verbatim. **Recommend:** assume identical within the RdSAP +family; cross-check each version against `epc_codes.csv` during grilling and add a per-spec cascade +override *only* where the corpus proves a code diverged. Don't pre-build translation layers. + +### Q4 — Schema-fix mechanism. Same `kw_only` + data-driven required→optional? +**Recommend: yes, unchanged.** Each placeholder schema over-constrains identically (single-example +generation). Run the one-pass corpus scan to enumerate all missing-required fields at once (not +whack-a-mole), then default them. Mechanical, low-risk, proven. + +### Q5 — Shared synthesis helper vs per-mapper copy (the architecture fork). +20.0.0's synthesis lives in `_synthesise_20_0_0_sap_windows` + inline mapper blocks. With 19.0 we'll +have a **second instance** — the classic extract trigger. **Recommend:** once 19.0 is green, extract a +single spec-parameterised `_synthesise_reduced_field_windows(glazed_area, tfa, glazing_type)` (and +shared lighting/hot-water/ventilation helpers) so 18.0/17.x are near-free and the coefficients live in +exactly one place. Defer the extraction until 19.0 confirms the shape (avoid abstracting from one +example). This is the `/improve-codebase-architecture` hook — a deep module behind a small interface. + +### Q6 — Per-spec field availability. +Do 17–19 actually lodge the synthesis *inputs* 20.0.0 relies on — `instantaneous_wwhrs` (bath room +counts), `low_energy_fixed_lighting_outlets_count`, `percent_draughtproofed`, `open_fireplaces_count`, +`multiple_glazing_type`? Older specs may omit or rename some. **Recommend:** profile each corpus up +front (one-pass field-presence scan); where a 20.0.0 input is absent, degrade gracefully to the +calculator's own default rather than fabricating — and record the gap in a test name. + +### Q7 — Dispatch wiring + acceptance bar. +**Recommend:** per spec, add the `schema_type` branch to `from_api_response` (wrapped in +`_clear_basement_flag_when_system_built` like the others) and promote its corpus into the strict +parse+map bucket in `test_mapper_corpus.py`. Smoke-check with `scripts/eon/find_epc_data.py` (extend +the UPRN list with that spec's certs) — our re-score should track the lodged figure within a sane band. +The formal SAP-score *value* test stays deferred (same as 20.0.0) until we choose to land it. + +### Q8 — Validation-Cohort / is there ANY cross-check? +Same rule as 20.0.0: a pre-SAP10 cert has no same-spec lodged figure to validate against, so synthesis +assumptions go in code/test names. **But probe one opportunistic anchor:** a single UPRN re-lodged +across spec versions (e.g. a dwelling with both a 19.0 and a 20.0.0 cert, unchanged between) — our +re-score of both should roughly agree. **Recommend:** if dual-lodged UPRNs surface during harvest, keep +a handful as a cross-spec regression anchor; don't block on it. + +--- + +## How to reproduce / kick off (19.0 first) + +```bash +# 1.

We want each re-mapped to the current `EpcPropertyData` so its historical certs can be +**Rebaselined**. This ADR records the *family-level* coefficient decision; `18.0` is the first instance +and the worked example. (Order set by direction 2026-06-11: **18.0 alone, end-to-end, first**; `17.1` +is a separate later effort.) + +ADR-0027 left one question open for the rest of the family: do later pre-SAP10 specs **reuse** 0027's +fitted coefficients (`0.148 × total_floor_area × band_multiplier`, multipliers +`{Normal 1.00, More 1.25, Less 0.81, MuchMore 1.51, MuchLess 0.62}`), or **re-fit** per spec? The +initial direction (2026-06-10) was *re-fit from each new corpus's own data — do not inherit by default*. +Profiling the harvested `18.0` corpus (1000 certs from `certificates-2018.json`, ~82% of that dump) +showed why a literal re-fit is **not achievable**, and — more usefully — that it is **not necessary**: + +- **The corpus cannot self-fit the glazing/floor ratio.** A reduced schema records `glazed_area` as a + *band*, not per-window m². `18.0`'s population is **958/1000 band-1 (Normal)**, and only **10/1000** + carry a lodged `sap_windows` array at all. So there is no measured glazing column to regress on for + the band that dominates the stock — the exact constraint ADR-0027 anticipated. +- **The 10 rich certs are systematically the outliers, not a representative sample.** They are + **9× band-4 ("Much More Than Typical") + 1× band-5 ("Much Less")**, with **zero band-1**. The + dwellings that bother to lodge full per-window geometry are the unusually-glazed ones. A "fit" off + these would measure band-4 dwellings, then dividing by the band-4 multiplier (1.51) only reconstructs + `0.148` — circular. +- **Where the corpus *can* be measured, it reproduces ADR-0027's model almost exactly:** + + | Band | 18.0 observed glazing/floor (n) | ADR-0027 predicts (`0.148 × mult`) | + |------|---------------------------------|------------------------------------| + | 4 (MuchMore, ×1.51) | **0.223** (n=9) | **0.223** | + | 5 (MuchLess, ×0.62) | **0.086** (n=1) | **0.092** | + + So the new corpus's own data **validates** the inherited coefficients rather than contradicting them. +- **Integer code spaces are identical.** `built_form`, `glazed_area`, `glazed_type`, and + `mechanical_ventilation` were diffed against `datatypes/epc/domain/epc_codes.csv` for + `18.0` / `17.1` / `20.0.0` / `21.0.1`: byte-identical for every code the corpus uses (`glazed_type` + 1-8 + ND; `built_form` 1-6 + NR; `glazed_area` 1-5 + ND). The cert-side codes never reach 21.0.1's + later extensions. So the verified 21.0.1 glazing/sheltered-sides cascades apply verbatim — no per-spec + override. + +## Decision + +For the pre-SAP10 RdSAP family, **inherit ADR-0027's coefficients and validate the transfer per spec — +do not re-fit by default.** Concretely, for `18.0` (and as the rule for `17.x`/`19.0`): + +- **Reuse `0.148` and the band multipliers unchanged.** The corpus structurally cannot self-fit them + (96% band-1, zero measured band-1 windows), and where it can be measured it reproduces the inherited + model to within rounding.

For `18.0` that is 10 certs direct, 990 + synthesised. +- **Route through the existing verified cascades verbatim** (glazing-type, sheltered-sides), per the + code-space diff above. +- **Schema parse fix = ADR-0027's mechanism plus one additive change.** (a) `@dataclass(kw_only=True)` + + data-driven required→optional: any field present in <100% of the corpus gets a default (`[]` for + lists, `None` otherwise) — for `18.0` that is `lzc_energy_sources`, `glazing_gap` + (`Optional[Union[int, str]]` — the corpus lodges str, int, **and** absent), `pvc_window_frames`, and + scattered `SapBuildingPart` / `AlternativeImprovement` / `PhotovoltaicSupply` fields; this takes the + parse rate from 14/1000 to 1000/1000. (b) **Add a `sap_windows` field** — the placeholder `18.0` + schema omits it entirely, so without this the 10 rich certs' lodged geometry is silently dropped at + parse time, defeating the direct-use rule. + +Because there is still no same-spec ground truth (**Validation Cohort** rule), every synthesis +assumption is recorded in code comments + test names, exactly as ADR-0027 requires. + +## Consequences + +- **The coefficients are now shared across specs.** Changing `0.148`, a band multiplier, or the 4-way + orientation split moves **every** rebaselined 20.0.0 **and** 18.0 score (and any 17.x/19.0 that later + joins). The blast radius of ADR-0027's named-constant block grew; that is the cost of transfer and the + reason the constants stay in one place with their derivation recorded. +- **The transfer is validated, not the absolute fit.** The band-4 match (0.223 obs vs pred) confirms the + *model shape* carries from 21.0.1-era stock to 2018-era stock; it does not independently establish the + base ratio for band-1, which remains inherited. Revisit if (a) the retired **RdSAP 2012** band→m² + formula is sourced, or (b) a same-spec Validation Cohort becomes available. +- **No cross-spec anchor exists in the current corpora.** A dual-lodged UPRN (same dwelling certified + under two specs) would let two re-scores cross-check, but the year-capped corpora have **zero** UPRN + overlap (18.0∩20.0.0 = 0). A true anchor would have to be *manufactured* via a targeted dual-lodged + harvest (scan the 2018 and 2022 dumps for shared UPRNs) — deferred, not part of landing 18.0. +- **Acceptance bar matches 20.0.0 (ADR-0027):** the corpus test promotes `RdSAP-Schema-18.0` into the + strict **parse + map** guard (1000/1000 return `EpcPropertyData`); it does **not** assert calculator + scores. Scoring is spot-checked manually via `scripts/eon/find_epc_data.py`; the formal score-value + test stays deferred. Expect wider lodged-vs-recalc deltas than 20.0.0 — the lodged 18.0 figure is on + an older SAP version, so it is Lodged Performance, not a target. +- **Synthesis stays copied for the first instance; the shared helper is deferred.** `18.0` adapts + ADR-0027's synthesis inline (one new instance). The shared, spec-parameterised + `_synthesise_reduced_field_windows` is extracted when `17.1` lands (the second instance), pulling + 20.0.0 + 18.0 + 17.1 through one coefficient block — avoiding abstraction from a single example while + preventing three divergent copies.
