March 2026 performance summary for polkadot-fellows/runtimes: Security-focused hardening of the emission logic completed. Removed outdated pre-hardcap emission code and replaced with a hardcoded value, reducing complexity and attack surface. Eliminated the March2026TI storage dependency and related legacy paths, improving runtime determinism. Added an empirical verification test (new_march_ti_const_is_empirically_correct) to validate the new hardcoded constant. Consolidated code cleanup and security improvements into a cohesive runtime inflation path, aligning with the #1112 cleanup objective. Collaborative changes with cross-team reviews; co-authored contributions where applicable.

December 2025 Highlights for polkadot-fellows/runtimes: Delivered the Hard Pressure issuance model with a stepped inflation curve, enabling a gradual convergence toward a defined target supply and aligning inflation with governance decisions (referendum 1710). Key technical changes include implementing a general stepped curve, integrating it into era_payout calculations, and adding tests to verify the new inflation behavior. Ported relevant tests from the previous inflation model to the AHM branch to ensure regression safety. No major bugs reported this month for this repository. The work enhances predictability of token supply, governance alignment, and test coverage, supporting stable economic policy deployment.

March 2025 monthly summary for clangenb/polkadot-sdk: Key feature delivered was Genesis Storage Serialization with Serde Derives integrated into the polkadot-sdk-frame derive and prelude modules, enabling runtime genesis storage types to be serialized and deserialized via serde. The change adds serde::Serialize and serde::Deserialize derives and guides consumers to add serde as a dependency or use #[serde(crate = ...)]. Commit 9d9ae348fc92e50004cb91c55a168a4cc30c0525 (Add Serialize & Deserialize to umbrella crate derive module, #7764).

Monthly work summary for 2025-01 focusing on standardizing storage access patterns and improving maintainability in clangenb/polkadot-sdk. Implemented a storage access refactor to replace pallet::getter with StorageItem::<T, I>::get() for pallet-grandpa, consolidating storage access across runtime modules and reducing future maintenance risk. The change aligns with Substrate best practices and paves the way for easier refactors in other pallets.
