Module coverage¶
Updated each session as modules reach implemented / parity-verified status.
| Module | Status | Phase | Parity source | Notes |
|---|---|---|---|---|
quantities |
implemented (some lines BLOCKED) | 1 | 1a_boq_input_lca.xlsx |
VALIDATED lines within 0.1% of CORRECTED totals. C1–C4 corrections applied. C3 (slab mesh) BLOCKED pending Chiwara attribution — steel_rebars total excludes slab contribution. C5 (anti-termite area) EXPERT-JUDGEMENT pending. |
lca.a1_a3 |
implemented (4 materials BLOCKED) | 1 | 2_lca_vn.xlsx |
E = weight × factor (VALIDATED). 14 materials computable within 0.1% of spec §4; per-material always returned with verdict + geographic tag (decision #26). BLOCKED: Earth (decision #26 hard block), Crude oil (anomalous 134), Floor Tiles (anomalous 5.09). PROVISIONAL: Antirust paint (CORRECTED 4.87). Aggregate total is None while any material is not COMPUTED — incomplete_reason lists the four. All computable factors provenance-BLOCKED pending ÖKOBAUDAT UUIDs. |
lca.a4 |
implemented (15 of 18 materials BLOCKED) | 1 | 2_lca_vn.xlsx |
A4_i = Σ_legs (mass[t] × distance[km] × factor[kg CO₂-eq/t·km]) (VALIDATED). The workbook's truck-power form reduces algebraically to this per-t·km form — parity exact to double precision (spec §3.1, §6). Mass read from the LCI mass path; quantities never re-derived. Both transport factors provenance-BLOCKED: road (uncited 0.26 kg CO₂-eq/kWh, thesis says 0.27 / 386 kW and cites nothing either) and sea (A4!L11 = 182.4/(F11*N11) back-solved from an unexplained constant, broadcast via $L$11). Decision #26 admits only IPCC EFDB or an ÖKOBAUDAT transport EPD. Aggregate total is None; Water, Crude oil, Waste Oil are on-site (zero distance) and COMPUTED at 0. Sourcing tasks A4-1/A4-2 are the gate. |
lca.a5 |
implemented (site energy only; all 3 plant items BLOCKED) | 1 | 2_lca_vn.xlsx |
A5_e = power[kW] × usage[h] × factor[kg CO₂-eq/kWh], share = A5_e/Σ (both VALIDATED). Already in the EN 15804+A2 energy-carrier form — no algebraic reduction needed, parity exact to double precision (spec §3, §6). First stage that is not material-keyed: one row per item of site plant (generator, cutting machine, welding machine), keyed on SiteEquipment. The single site-energy factor is provenance-BLOCKED: A5!F5:F7 = 0.26 kg CO₂-eq/kWh is an uncited literal on a stage decision #26 names energy-linked and BLOCKS on EU grid factors outright; the same workbook carries a Senegal grid factor 4.2× larger (B1!D5 = 1.1, itself unverified, AR-09); and the largest consumer is a diesel genset, which draws no grid electricity at all. Aggregate GWP total is None, but total_energy_demand is reported (1 080 kWh) because power × hours needs no factor. Scope is deliberately partial: the reference calculation omits installation losses, site water, packaging, temporary works and plant/worker transport — not invented here, stated in scope_note on every response (AR-58). AR-54 is the sourcing gate. |
