Khalim Conn-Kowlessar 6baf66cdde Slice 68: party-wall "U Unable" + central_heating_pump_age_str → 1 diff left
Closes 4 of 5 remaining cohort 000474 diffs (5 → 1):

**Mapper:** Add "U" → 0 to `_ELMHURST_PARTY_WALL_CODE_TO_SAP10`. The
modal cohort lodgement Summary §7 "Party Wall Type: U Unable to
determine" was previously falling through to None; the cohort hand-
built convention uses 0 as the explicit "unknown" sentinel. The
cascade resolves both 0 and None to the same `u_party_wall` default
(0.25), so cascade output is unchanged. Closes 3 diffs (one per bp).

**Hand-built:** Set `central_heating_pump_age_str="Unknown"` on cohort
000474 Main heating detail (post-construction since the helper
doesn't expose the kwarg). Matches the Elmhurst mapper's surfaced
value from Summary §14 "Heat pump age: Unknown" — the str dual-
encoding internal_gains.py reads. Closes 1 diff.

All 66 cohort cascade pins remain GREEN at 1e-4. Pyright 35-error
baseline preserved on mapper.py; 0 errors on the hand-built file.

Remaining 1 diff on cohort 000474:
- `sap_windows: LEN 7 vs 5` — the cohort hand-built collapsed §11
  by glazing-type × orientation × bp group (preserving total area,
  cascade-equivalent but not field-equal); the mapper extracts 1:1
  with the worksheet's 7 §11 table rows. Next slice will expand the
  hand-built to 7 individual SapWindow entries matching the mapper.

domna-domain

Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.

Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.

Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
