[2026-08-03 lane 4 — citation relevance] The governing principle of this pass. A citation earns its place by CONTAINING THE VALUE IT BACKS, not by returning 200. Two citations here are RETIRED rather than repointed because no paragraph anywhere in them ever supported the value they were attached to: 49 CFR 393.5 is a definitions section, and the ATP Agreement governs thermal performance with no prescribed body dimension anywhere in its annexes. Swapping either for a live URL that also fails to support the value would have looked like progress and been none.

Schmitz Cargobull's real public domain is cargobull.com. NO SERVED VALUE CHANGED on this record in this pass. [2026-08-05 vehicles lane 2 — LDM divisor modelled additively] ldmDivisorWidth/ldmDivisorBasis are NEW FIELDS. NO EXISTING VALUE CHANGED on this record. They exist because a consistency guard was reading internalDimensions.width as the loading-metre divisor, and it is not one. This record's width is the internal SHELL width; 2,400 mm is the divisor the loading-metre convention is DEFINED on. Both are true and they answer different questions — they were sharing one field, which is the same defect class as the height-0 sentinel and the undeclared pallet-count basis. EVIDENCE, fetched and read 2026-08-05: 23 publishers were probed and every single one that states a divisor states 2.4 m, with zero variance — DHL Freight, Gebrüder Weiss, sennder, Savino Del Bene, DSV and ExFreight on the carrier/forwarder side; Soloplan (CarLo), IMPARGO, Cargo-Planner, EasyCargo, Goodloading, Routix and Pallet3D among load-planning vendors; TIMOCOM and Trans.eu as exchanges. Six of those were re-read directly rather than taken on report, and are cited on this record. WHY THE BASIS IS \"ldm-convention\" AND NOT A MEASURED USABLE WIDTH: no publisher in the corpus distinguishes a usable loading width from an internal shell width, and TIMOCOM prints a 2.45 m articulated loading-space width on the SAME PAGE as its 2.4 m divisor, while Access Logistics does the same. So 2.4 m is demonstrably not offered as a measurement of any trailer. Soloplan calls it a \"standardised value in Germany\"; Cargo-Planner calls it \"a constant\". Naming this field usableLoadingWidth would have asserted a measured quantity the evidence does not support, so it is named for the job it does. A per-vehicle measured usable width remains UNSOURCED and is deferred to vehicles lane 3. NO SERVED LDM VALUE CHANGED for this record: every compute site already divided by 2.40 m, so the published loading-metre figures were correct all along. What was wrong was the guard's comparator, which pointed at the wrong field. [2026-08-06 vehicles lane 3 phase C] THE 44 t / AXLE-CONFIGURATION CONTRADICTION, RESOLVED. This record stored grossVehicleWeight 44000 alongside axleConfig \"2+3\". 2+3 is FIVE axles, and no read source puts 44,000 kg on a five-axle articulated combination. gov.uk \"HGV maximum weights\" (DVSA/DfT) indexes its table by vehicle type AND axle count: the AWR column places 44000 on the \"Articulated vehicles | 6\" row, and its footnote 3 states the split in terms — \"Each part of the combination must have 3 axles and the trailer must have road friendly suspension\" — i.e. 3+3. The five-axle row is 40000 (AWR) and 38000 (C&U). The 44000 that does appear in the C&U five-axle cell carries footnote 2, \"Operation at over 38000kg under the C&U regulations is restricted to combined transport operations\", so it is not a general allowance; and the page forbids mixing regimes: \"vehicles may only comply with one of the regulations - individual parts of the 2 regulations cannot be combined.\" Directive 96/53/EC Annex I agrees: 2.2.2(a) puts a \"two-axle motor vehicle with three-axle semi-trailer\" — the 2+3 case, spelled out — at 40 tonnes, and its 44-tonne clause 2.2.2(c) requires a THREE-axle motor vehicle carrying containers or swap bodies \"in intermodal transport operations, up to a total maximum length of 45 feet\", so 44 t cannot reach a 2+3 at all. (2.2.2(d) raises 2+3 to 42 t, intermodal only.) WHICH FIELD WAS WRONG, decided per record rather than by default: axleConfig. The decisive evidence is internal — this record's own rationale already read \"max GVW 44t for 6-axle (2+3+1 or 2+3) artic on the UK derogation\". The rationale said SIX axles while the field said five, so the record always described a six-axle vehicle and the axleConfig string was simply mis-entered. Correcting the string preserves what the record is about; dropping grossVehicleWeight to 40,000 would have changed it into a different vehicle. Corroborating that reading, this is one of the standard UK/EU fleet artics, not a light five-axle unit. axleConfig \"2+3\" -> \"3+3\". grossVehicleWeight UNCHANGED at 44000. The correction is what makes the gov.uk citation genuine: fields_supported for that source is derived by matching this record's category and axle count against the published table, so before the fix it backed nothing and after it backs grossVehicleWeight. NOT CORRECTED HERE, and flagged rather than guessed: Directive 96/53/EC still backs nothing on this record, because its unconditional six-axle maximum is 40 t and its 44 t is intermodal-conditioned while this trailer is general-purpose. That citation is retained with a recorded no_support_reason rather than removed, because dropping a source is a separate decision from recording that it does not carry the value."}},"_source":{"type":"reference","authority":"EU Directive 96/53/EC, UK DVSA, 49 CFR (regulatory limits)","provenance_status":"pending-verification"}}
