July 2025 monthly summary for developer work across bob-collective/bob and pubky/pkarr. Focused on delivering targeted features, improving observability, and restoring stability in build/test workflows. Business value delivered includes clearer operational visibility, faster debugging for relayer events, reduced integration risk from API surface changes, and a more maintainable codebase for JavaScript bindings and WASM workflows. Key features delivered - bob-collective/bob: Relayer Block Hash Handling and Logging Improvements - Rename relayed_blockhash to best_blockhash in the relayer module for clarity; adjust logging for fork detection from debug to info; extend regtest sleep to 150ms to allow more time for block propagation; fix debug log to display the best block hash instead of the relayed block hash. - Commits: 2012cf9e394c735546cb0665b6483c38b75f03af; e8785daa586e185198fb8005db229dc736ade9eb - pubky/pkarr: Unified JavaScript Client API - Refactors JavaScript bindings to use a unified pkarr::Client instead of a separate RelaysClient, simplifying the API and consolidating relay functionality within the main Client. - Commit: 25910d77d4aed96ed40690ef1aeadc0929f0892f - pubky/pkarr: Rollback to stable WASM/JS bindings and build workflow (bug fix) - Reverts changes to WASM build/test workflow, pkarr crate dependencies, JS bindings dependency versions, and build configuration to restore a stable, working state. - Commits: 4df701590da66f7bfa8bb9e2109189357ddc67a8; a0ae0a91a19064c3807082d73618e4860bc010d2; fc2d5d476b77e1ebafe3a53ef52cd159c041ada1; c1815308de58e47e6058adc7db8efec3eba29d66 Major bugs fixed - Reversion of WASM/JS bindings and build workflow to a known-good baseline, restoring stable dependency versions and build configuration, reducing flakiness in CI and local builds. - Ensured cargo checks and dependency resolutions align with pre-change stable state, mitigating runtime and test failures after experimental bindings changes. Overall impact and accomplishments - Increased reliability and observability of the relayer by exposing best_blockhash and improved logging, accelerating diagnosis of fork events and block propagation issues. - Streamlined API surface in pubky/pkarr by unifying client access under pkarr::Client, reducing maintenance overhead and potential integration points. - Restored build stability and test reliability across WASM/JS bindings and related toolchains, lowering release risk and enabling smoother iteration cycles. Technologies/skills demonstrated - Rust: module refactoring, logging, and debugging improvements in the relayer. - WASM/JS bindings: stabilization and unification of client bindings; dependency/version management. - Build/test workflows and CI: reverting to stable configurations, Cargo.toml stewardship, and workflow reliability. - Cross-repo coordination and change management to minimize integration risk and maintain business momentum.

June 2025 monthly summary for bob repo focusing on Relayer module improvements, API enhancements, testing/performance improvements, observability, and contract bindings with deployment scaffolding. Highlights include significant refactor of Relayer core, initialization simplification, public API expansion (contract_address getter), regtest performance tuning, improved logging via tracing, and generated PellBedRock bindings with deployment helper. Removed an unnecessary period-start hash validation in FullRelay contract, simplifying validation and tests.
