Fix hardcoded leasing weights

[UnArbosFour]

SubnetLeasingWeightInfo contains copied benchmark constants from 2025, while generated weights were refreshed in July 2026. For termination, the helper reports roughly 56.6m + 0.913mk, versus the generated 100.6m + 1.594mk. That likely causes excessive post-dispatch fee refunds.

This PR replaces the local formulas with generated WeightInfo calls, adds post-dispatch weight tests, and deletes the duplicate table.

🛡️ AI Review — Skeptic (security review)

VERDICT: SAFE

VERY HIGH account-age/activity scrutiny, mitigated by repository write access; no Gittensor association found; fix/leasing-weights → staging.

Static review found the generated weight calls match the benchmark parameter semantics: registration uses the crowdloan’s total contributor count, while termination restores the excluded beneficiary with a saturating increment. No dependency, privileged-origin, workflow, or supply-chain changes are present.

Findings

No findings.

Conclusion

The change removes stale underweight formulas and correctly reports the newer generated post-dispatch weights. No malicious behavior or security vulnerability was found.

🔍 AI Review — Auditor (domain review)

VERDICT: 👍

UNKNOWN Gittensor association; very new contributor with limited history, mitigated by repository write access.

The generated weight functions match the benchmark parameter semantics: registration uses the crowdloan’s total contributor count, while termination adds the beneficiary excluded from SubnetLeaseShares. The new tests cover both post-dispatch weight paths, including committed-backend behavior for clear_prefix.

No spec-version bump is required for the staging base branch. The overlapping PRs address unrelated work, so neither is a duplicate. No runtime commands were needed for confirmation.

Findings

No findings.

Conclusion

The change correctly replaces stale weight formulas with generated weights and validates the reported post-dispatch values. It is ready to merge.
