Jun 1, 2026June 2026: Garden Co Jazz — delivered observability and resilience enhancements for the jazz-tools server, driving higher reliability and better telemetry for monitoring and capacity planning. Key outcomes include enabling OpenTelemetry by default across published server versions and implementing robust upstream connection retry and timeout logic, with related transport-installation refinements. After an initial attempt to bound retries with connect deadlines was reverted, a final fix was applied that stabilized upstream sync behavior. These changes reduce upstream failures, shorten incident resolution times, and provide actionable telemetry for proactive operations.

Jan 1, 2026January 2026 (garden-co/jazz): Focused on strengthening data integrity, reliability, and developer productivity through comprehensive validation, safer creation flows, and enhanced organizational capabilities. Implemented initial schema validation on create with early fixes to prevent malformed entity creation. Introduced Account.createAs timeout and onCreate credentials flow with end-to-end validation, reducing hang scenarios and improving security posture. Hardened runtime validation across CoValue/CoFeed with a Zod-based refactor, richer validation options, and global defaults, along with associated tests and API cleanup. Expanded validation coverage across list and map operations (CoList, colist, coMap.set, and applyDiff) with tests and improved error propagation. Added group naming support and tightened schema equality checks, paired with validation order propagation to ensure correctness. These changes collectively improve data quality, reliability, and developer productivity, enabling safer feature delivery with clearer feedback loops.

Dec 1, 2025December 2025 (Month: 2025-12) – Garden Co Jazz: focused on reliability, configurability, and data integrity in the inspector. Delivered a standalone inspector with configurable syncServer, account switcher, updated routing, and a new account management modal, enabling deployment flexibility and improved UX (commit 68acca42d0a21cb77b6738969e0bf660dcd100e3). Fixed inspector transaction grouping to correctly associate transactions with groups and prevent misclassification of CoMap transactions, with tests validating the handling (commit 9ca9e723976cfb12833761575db95217f9ce7002). Restored stability by reverting chat example changes to the previous functionality (commit 238c5e4a297e6e898e92167ac2ba776ed7d04df9). Improved data integrity and change tracking by enhancing coMap.getEdits to include deleted keys (commits b27dbc24fa18ab38838343a49667eff6eda7175e; 9cc2770ba78c5c6b627762c9058cb06fda89cb77).

The month delivered several high-value features, targeted fixes, and reliability improvements across the core product and Jazz Tools, aligned with business priorities for safer secret management, improved UI feedback, scalable role-based access, and improved image handling in RN environments. Key features delivered: - Auth SecretStorageKey Rename and Documentation: Renamed storageKey to authSecretStorageKey across core, examples, and docs; updated usage examples and props to reduce confusion and enforce consistent secret handling. - Inspector UI Enhancement: Show coID in list view and handle unavailable items, with accompanying fixes to ensure consistent rendering and state. - Manager Role: Introduced manager role and associated access controls; enabled role-based workflows and security guarantees. - Media Tools: Expo Image Manipulator support for image resizing in jazz-tools/media, enabling RN image processing without custom shims. - Inspector group view enhancements (Jazz Tools) and related UI consistency improvements across the inspector suite. Major bugs fixed: - Inspector Examples: End-to-end tests on the table-viewer component were fixed to restore test reliability. - Jazz-tools: Fixed createImage return type alignment with the expected API (#3057). - Manager Invitations: Prevented managers from inviting other managers, enforcing proper role boundaries. - Invite/Role Type Safety: Fixed types in createInvite's role to improve compile-time safety. - Account Schema: Synchronised co.account().create() type with Account.create() to avoid type drift. - Others: Fixed inspector render in Svelte; removed silent failure in RemoveMember revert; addressed various reinforcement fixes to ensure consistency. Overall impact and accomplishments: - Reduced risk and ambiguity around secret storage keys by standardizing naming and documentation, improving developer confidence and security posture. - Strengthened access control and role semantics, reducing potential misconfigurations and security gaps in multi-user environments. - Improved developer experience and application reliability through UI refinements and robust E2E test stabilization. - Enhanced image handling capabilities in RN contexts, broadening platform support for Jazz apps. Technologies/skills demonstrated: - TypeScript/type-safety improvements and refactoring (role types, schema alignment, naming changes) - React Native integration with expo-image-manipulator for image resizing - End-to-end test reliability and quality assurance practices - UI/UX consistency improvements in inspector tooling and Svelte rendering fixes - Documentation, examples, and prop naming discipline across core and docs
