Release SkipHow 4.7.0 routing and verification health

[mzored]

SkipHow 4.7.0 makes delegate model and effort selection account for the total expected cost of a verified acceptable outcome. It also diagnoses recurring disproportionate verification cost at the responsible layer while preserving unique high-fidelity evidence and required delivery gates.

Routing keeps parent-independent, provider-neutral choices. It distinguishes missing context, excessive context, and capability failures before retrying, and keeps delegation economics separate from model selection. The kernel carries the invariant and the existing delegation reference supplies guidance. No new workflow, routing state, model tiers, host binding, or authority is introduced.

Four executable verification-health fixtures from the original candidate remain intact. Five new read-only routing cases cover cheap verification, hard-to-detect errors, and three distinct miss causes. They cannot prove actual delegate settings or savings.

Validation for d95a268:

• Full local python scripts/check.py passed with pinned dependencies on Python 3.14.7. A final grammar correction in the decision ledger was followed by the focused package/document check, which passed.
• Corpus checks passed, 48 tests. Final git diff --check passed.
• Local Codex and Claude strict schema validators both passed.
• Independent read-only review found no qualifying defects against the supplied spec or outcome contract. The prior verification-health fixture defect remains resolved.
• No paid model sessions or clean-install smoke were run. Package structure and host bindings are unchanged. Routing, verification-health behavior, effective delegate settings, and savings remain UNVERIFIED.

The owner has explicitly authorized publication. Merge after final PR CI, verify integrated main CI, then publish v4.7.0 through the existing release workflow and verify the release and site destinations.
