Theme 1 — EPC card provenance. New resolveProvenanceSignal (pure, unit-
tested) + resolveProvenance expose provenanceSignal ("estimated" /
"remodelled" / "none") and the lodged headline on property-meta. The
building-passport card shows a "Lodged EPC" badge on re-modelled
properties (even within-band), never on predicted ones; the existing
"estimated from nearby homes" banner already covers predicted.
Theme 2 — portfolio table. "Current EPC" + reporting now read the
effective baseline (effectiveSapSql/effectiveEpcBandSql); a dedicated
"Lodged EPC" column reads the source-gated lodged value (blank for
predicted); a "Predicted" pill marks estimated rows; a provenance filter
is added and the broken currentEpc/lodgedEpc filters (on null row
columns) point at the effective/lodged baselines. Expected EPC now uses
the default plan's post rating (expectedEpcRating, unit-tested) instead
of current + Σ rec SAP, which double-counted across plans (732385: A→C);
the same rec aggregate is scoped to the default plan, fixing the Cost
column's 2x double-count.
See ADR-0002. Pure logic covered by provenance.test.ts + expectedEpc.test.ts;
SQL/query/UI verified against live properties 732385 and 729529.
