Source heads: lance-graph f87081c; SIMAF a420b48822e91df39e7b170a711eddf571e79db5; SIMAFPort 381d6c2e6ce47765a6460268bf15b9cec46ff2be; SMB-Core-Middleware 363314048483c3883d2734cbe5cd51d10fb5e8a6; SiMAF-rs empty; odoo-rs ef03731c00f5e2796df3185bd69526153af7e253 (head only, deferred). CATS has 23 leaf fields: string, pernr_d, kunnr, ps_posid, aufnr, catsquantity, lstar, abap_bool. Native DDIC scale is not defined in this corpus. ABAP hashes named values; SMB hashes bare normalized values, and has int TenantId plus additional ApprovalStatus. No silent parity claim. ClassView is cold metadata; Quack GroupBy already lowers onto mask-risc borrowed LaneRef and i32-to-i64 sum. CascadeShape is a 12-byte facet grouping, not a fit for lossless CATS quantities or CHAR24. No implementation in W0.
W4: Original pinned C# sources compiled with .NET 8.0.425: all 23 fixture values, SMB ordered projection and HMAC match Rust; Python HMAC also matches. ABAP is source-inspected, not runtime-executed. Preserve explicit incompatible ABAP/SMB hash profiles; refuse unsupported rounding, Unicode normalization, and short notes(50) BAPI fixtures. BAPI uses selected original assignments, never posts an activity aggregate under invented dimensions.
W5: the same NUMC adapter serves employee and approver, UTC adapter serves four fields, and width checks plus lossless dictionaries serve the evidenced CHAR domains. Keep these local; no new generic SAP type system, fabricated scale or ALPHA exit is justified.
W6: after CATS fold and boundary differential pass, inspect odoo-rs ef03731c00f5e2796df3185bd69526153af7e253. Its mint_wide_mask delegates to the same contract constructor. Pin real account.move corpus/view inputs (216 fields, 57 selected); exercise high ordinal bits. No Odoo source changes or shared ERP metamodel.

… identity `BAPI_ORDINALS` (with positionally aligned `BAPI_PARAMETERS`) names the BAPI parameter order as a permutation of a selection of `FIELDS`; `bapi_sink` reads through it, so the wire struct is filled by the map and is the boundary's shape, not a copied normal form. Test pins that the map is a permutation over the canonical basis, matches the pinned ABAP assignment, and that every posted value equals the canonical value at the mapped ordinal.

The existing CATS sources have no path into the native field/fold ABI, and their claimed hash compatibility is false at current heads.
This adds a small, standalone
lance-graph-sapconsumer crate. Reviewable commits cover W0–W6, CI and the fold-first substrate update. It harvests 23 fields into a stable ClassView basis, binds column-oriented edge input to borrowed mask-RISC lanes, and delegates employee/date/activity sums to shipped Quack lowering. Names and dictionary strings stay outside execution. No SAP evaluator, DTO mirror hierarchy, JSON intermediate, new mask engine, or ERP framework.The executable slice returns DEV=17.000 and OPS=0.125, then emits three selected original BAPI-shaped assignments. Activity totals and posting assignments are distinct terminal sinks: grouped results cannot recover project/date dimensions. The original assignments are materialized only at the explicitly requested BAPI sink.
