fix(third-door): align with perfected package contracts from Downloads artifacts (refs #10 #11 #12 #13)
Source artifacts from the multi-model landing package (README + Super-Blueprint
+ ADR-0238/0239/0240 + goldtether/dynamic_manifold/surprise) are now the
contractual surface, implemented on the live algebra/* kernel:
- GoldTetherMonitor.residual/update/may_relax_hitl/force_reset/autonomy
- signature_aware_pca (5×K, null-safe), conformal_procrustes, cartan_iwasawa_extract
- surprise_residual (Minkowski) + dual_procrustes_surprise audit dict
Package stubs (core.algebra.backend placeholders, scipy, identity-only
Procrustes) are replaced with dual-corrected Cl(4,1) operators. ADRs match
package decision language; docs/adr remains canonical with decisions redirects.
34/34 Third-Door tests + 7/7 ADR-0199 arena regression green.
