Per each cert's notes: 7536 is a glazing-U gap (S0380.97 glazing_type=2
Table 24 default vs the cert's higher lodged U on multi-age bps) — the
tractable target; 2130's SAP +1 is a PV-β cohort cascade interaction, not
a fabric line. The earlier "multi-part wall, shared cause" label was wrong.

Add a CURRENT PRIORITY section: of 53 pinned golden certs, 3 have non-zero
SAP residual. 2130 (+0.85 cont) + 7536 (+0.57 cont) are real multi-part-wall
fabric over-predictions (the drive-to-zero targets, possibly one shared
cause). 0240 (-1) is architectural — the lodged 73 needs an unpreserved
2013+ pump; document the cause, do NOT re-pin (user decision).

Record the £120 standing-charge fix (Table 12 note (l) + §C3.2, case 14
(351)), the corrected diagnosis (standing charge, not cost scaling — the
4.24 p/kWh heat price was already right), the double-count avoidance, and
the remaining ~7% demand over-count (SAP -2). Bump HEAD/baseline/next-slice.

Record the heat-network fuel-code collision fix (EPC 20 'mains gas
(community)' → Table-12 51), case-14 validation, and the remaining
cost-scaling gap (heat-network cost path missing 1/heat_source_eff).
Bump HEAD/next-slice; update shipped + audit tables.

Record the community mains-gas BOILER worksheet (case 14): target (386)
heat-network CO2 factor 0.2640, distribution loss 1.49, code 301. 9390
decomposition: PE matches (204 vs 205), CO2 6.5x low (collision), SAP +4
separate cost gap.

Record the roof closure (vaulted NI → Table 18 col 1 0.16, cohort-arbitrated
not the guessed 0.25), the AGENT_GUIDE suite-command gap (sap10_ml/tests/ not
run) + pre-existing stone failures, cases 11/12/13 now available, and the
fuel-20 = community-gas (Table 12 code 51) note. Thread 2 still needs a
code-301 community-boiler + mains-gas worksheet (case 13 is code-302 CHP).

Update the mapper-bugs handover: Thread 3 closed via the cavity
"partial insulation (assumed)" → "Cavity as built" routing fix; record
the latent open question about the unvalidated "insulated (assumed)" →
filled-cavity test (slice S-B25). Bump HEAD/baseline/next-slice.

Records post-S0380.209 state: 0240 verdict (true SAP 72, register 73 = unpreserved
2013+ pump, proven 0=Unknown via 13 pairs), and three open threads — roof Ext1
"insulated (assumed)" U over-count (needs case 11 worksheet), community fuel-code
collision (API 18-25 vs Table-12 biomass 18-25; cert 9390 CO2 6x low; needs 9390
worksheet), and 0390 +7 demand-side gap. Plus the audit table of all 5 non-zero-SAP
golden certs.
