H-096 BUILD VALIDATION (software/construction only — NOT scientific evidence)

Validated with the dedicated validation profile at R9/R11 only.
R39/R45 were NOT run and remain fresh scientific holdouts.

Passed:
- Python 3.10-compatible source/import structure
- frozen K / PHASE_CARRY ensemble identity
- GR-closed generation and checkpoint path
- H-089 wall-continuum generation
- deterministic PHASE_CARRY route generation
- post-generation exact-GR scoring
- nearest GR/FV supported shelf = 100% in validation profile
- reflection symmetry to numerical precision
- monotonic validation-resolution continuum convergence
- progress meter

No validation result was used to change the H-096 full-run mechanics, R39/R45 cases,
or predeclared holdout criteria.
