Brings HANDOVER_MODELLING.md fully current: #1157 (Plan persistence) and
#1160 (Optimiser) closed this session; records the locked design
decisions (multi-phase deferred, Plan Measure term, reuse-live-tables
via SQLModel mirrors, pure-Python knapsack not mip), the gotchas (mip/CBC
broken on aarch64, moto missing, drive-Modelling-directly for fixtures
without lodged perf, seed materials per fired measure type), and the
remaining work (#1161 ventilation Measure Dependency + deferred fronts).

Records that the Elmhurst recommendation Summaries parse via the
extractor chain (not parse_site_notes_pdf), so the "parser gate" never
blocked the cascade pins. All four pins close at delta 0; loft 270→300
and the suspended-floor insulation-type field were the two gaps fixed.
Remaining: #1157 (HITL schema review) + ProductJsonRepository.

Captures issue status (#1153-#1161), the built compute spine, key
facts/gotchas (hand-built 000490 fixture, calculator entry, worktree-vs-main
import trap, test/commit conventions), and the two gates (parser fix -> wire
Elmhurst cascade pins; #1157 persist-Plan HITL schema review). For picking
the work back up in a fresh session.
