Two review points from @dancafc:
1) Rename the `Comparable` dataclass → `ComparableProperty` (it models one
comparable *property*; the collection stays `ComparableProperties`). Applied
across domain, repositories, orchestration, harness, scripts, and tests with a
word-boundary rename so `ComparableProperties` is untouched.
2) Move `PredictionTarget` out of comparable_properties.py into prediction_target.py
(where `PredictionTargetAttributes` + `build_prediction_target` already live).
comparable_properties.py now imports it; no import cycle (prediction_target no
longer depends on comparable_properties). Importers updated.
92 tests pass across the touched suites; pyright strict clean.

Bumps N_POSTCODES 40 -> 150 for the fetch script. Larger corpus (150
postcodes / 3719 certs) reduces leave-one-out variance and unblocks the
recency-template work (#1223), which regressed the noisier 36-target gate
fixture. Corpus itself stays out of git (gitignored /tmp + persistent
backup at /workspaces/home/epc_prediction_corpus_backup).

Bump N_POSTCODES 150 -> 40 as the gradual-growth step from the 3-postcode
smoke. 40 postcodes / 1113 certs / 578 leave-one-out predictions is enough
for stable, trustworthy metrics (the smoke's 2 usable postcodes were
dominated by oddball flats — floor_area mean|.| 52.6 there vs 12.7 here).
Resumable + reproducible (random.seed(2026)); raise again to scale up.

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.
