Buildability / Receipt
This public receipt window renders only fields present in the canonical receipt object, deterministic fixture receipt, or canonical evidence receipt. Missing compute, demo, hash, signature, approval, telemetry, and adoption fields stay explicit.

Verdict
Watch
Verdict is Watch because viability or proof quality is intermediate and should be re-evaluated before execution.
Time to first demo
Insufficient data
No first-demo timestamp, owner estimate, or elapsed demo receipt is attached to this surface.
Data
are handled separately via spectral norms as in Lemma D.2. Then for some explicit constants ππΎ β₯ 0, πΏπΎ,pre β₯ 0 depending only on the block parameters, |π’π‘(π₯)| β€ ππΎ + πΏπΎ,preβπ₯ββ,2
Truth Boundary
Buildability surfaces only report computed viability and proof receipts. They do not claim live production usage, pilot outcomes, founder sign-off, public Brier calibration, judge divergence, or external adoption unless explicitly sourced.
Compute

(48) π‘β₯0 sup Hence on the ball βπ₯ββ,2 β€ π one can take π(π ) βΆ= tanh(ππΎ + πΏπΎ,preπ ) < 1. (49) The strict inequality holds since ππΎ + πΏπΎ
