Kevin Gilper 7ce90da3a9 Run Stage 1 live: mechanism confirmed, taps show no attribute specialization
Installed V10 + the probe node on the render box, generated a controlled
reference set, and ran the encode-only selectivity harness on the real Krea 2
model. First actual measurement of the 12 text-layer taps:

- Mechanism confirmed live: probe reports feature width 30720 (= 12 x 2560),
  divisible by 12, so the tap split engages on the model (no fallback). Tap
  magnitude rises with depth.
- No strong per-tap specialization: after removing the depth-magnitude
  confound, every tap carries essentially the same attribute mix (palette
  0.20 / structure 0.33 / texture 0.35 / lighting 0.12; cross-tap std-dev
  ~0.01). Taps differ by overall magnitude (depth), not by which attribute
  they encode - only a faint depth gradient in the design direction, far too
  weak to justify the tables' 5x spikes. The "tap 8 = palette" premise is not
  supported.

Caveats recorded honestly (seq-mean signature, weak palette axis from a
near-neutral base, single scene). README Stage 1 updated with the result;
raw signatures + full write-up in local_records. Also fixes the probe graph
generator to supply the V10 card's full widget set (API validation).
