July 2025 monthly summary for jstz dev: FOCUSED on reliability and correctness in the Oracle module of the jstz transaction system. Delivered a critical bug fix that ensures dirty state is preserved and correctly propagated during key existence checks, smart function creation, and balance updates. Implemented in commit 58d59ce1b0df0171ac9a082bd23096338c19bfd1 with message fix(oracle): dirty for exists, sf create and add balance. This fixes stale or incorrect state from affecting subsequent operations and enhances overall transaction consistency.

April 2025 monthly summary for jstz-dev/jstz: Key feature delivered: Jstz URL scheme standardization across API, request handling, and deploy/run/withdraw workflows. Migrated all internal and external references from tezos:// to jstz:// and enforced exclusive jstz scheme for all requests, improving consistency and interoperability. No separate high-severity bug fixes were logged; bug-related work was included in the standardization effort. Impact: clearer integration points for partners, reduced ambiguity, and easier maintenance. Technologies/skills demonstrated: proto/schema migration, API design and request routing, cross-service reference updates, and schema-driven workflow changes.
