Behavioral Discrepancy between gtest and g1 runtimes

Behavioral Discrepancy Report (gtest vs g1, excluding weights)

Scope

This report lists runtime behavior differences found between:

• runtime/gtest/src
• runtime/g1/src

Weight files are intentionally excluded.

Discrepancies

1) Proxy type mismatch: TechnicalCommitteePropose missing in g1

• gtest: ProxyType::TechnicalCommitteePropose exists and is allowed to proxy TechnicalCommittee::propose.
  • Reference: runtime/gtest/src/lib.rs:156, runtime/gtest/src/lib.rs:191
• g1: this proxy variant and its filter arm do not exist.
  • Reference: runtime/g1/src/lib.rs:156

Behavior impact: A proxy authorization path available on gtest is unavailable on g1.

2) Smith issuance cap mismatch: SmithMaxByIssuer

• gtest: SmithMaxByIssuer = 100
  • Reference: runtime/gtest/src/parameters.rs:131
• g1: SmithMaxByIssuer = 12
  • Reference: runtime/g1/src/parameters.rs:138

Behavior impact: Smith certification issuance limits are much stricter on g1.

3) Membership renewal period mismatch: MembershipRenewalPeriod

• gtest: 56 * DAYS
  • Reference: runtime/gtest/src/parameters.rs:115
• g1: 2 * MONTHS
  • Reference: runtime/g1/src/parameters.rs:121

Using current shared constants, this is:

• gtest: 806,400 blocks
• g1: 876,600 blocks
• delta: 70,200 blocks (about 4.875 days at 6s/block)

Behavior impact: Membership renewal timing window is longer on g1.
