knowledge: D-ARW-0 shader-field lineage audit — target identity is the first falsifier

[AdaWorldAPI]

Follow-up to merged #1078. Documentation/source-audit only, no production changes.

Why

D-ARW-0 asked for current-source archaeology before restoring any historical cognitive-field geometry. This pass traces the live path from thinking-engine perturbation state through the DTO bridge, P64, shader hits, CE64 emission, Alpha, EWA and the historical Morton/lithography/Stockfish lineage.

Strongest current finding

P64 computes a concrete CascadeHit.target, but ShaderDriver::run lowers that hit to ShaderHit { row, distance, predicates, resonance, ... } where row remains the original BindSpace source row. The target is discarded. CE64 emission later reconstructs S = row % 256, P = 0, O = (row / 4) % 256.

That means the relation target selected by the P64 cascade is not present in the emitted CE64 identity. This is recorded as a BROKEN WIRE, not yet a bug, because a synthetic row-resonance edge could intentionally discard the target.

First falsifier

F-ARW-TARGET-1: make one source row produce two distinct P64 targets A/B at equal distance/predicate and observe emitted CE64 identity.

• distinguishable relation identity => finding false, NO BUY;
• same S/P/O identity => target loss proven.

No new DTO/carrier is authorized even if it fires. Audit existing reserved/local/receipt routes first.

Other corrections banked

• The old "without materialization" idea was not a blanket ban on LUTs: board: E-PERTURBATION-CONVERGENCE-1 — the five arc findings converge onto one pinned equation (council-ratified) #755 explicitly kept the PHASE plane immaterialized while permitting a shared materialized-or-analytic metric LUT.
• Current OGAR still records the 64→256→1024→4096→16k→64k→256k cascade as immaterialized Morton enumeration, but that does not prove the lost 4096 codebook↔64×64 mapping.
• Stockfish remains a systems/expert-iteration reference, not Morton evidence.
• EWA Spd2/sandwich and BindSpace's sigma index exist, but this audit does not find EWA consumption in the examined live ShaderDriver::run P64 path.
• Shader AlphaComposite and MedCare same-address AlphaOverlay are explicitly kept distinct.
• Historical ada-docs commit 9a7fe16d... independently confirms "Shared Lithography" + shared substrate + activation-mask vocabulary predates the current Java mask membrane.

Scope

Knowledge note only. No code, ABI, layout, DTO, tenant, scheduler, provenance, or Rubicon changes.
