Index-name compatibility across DDL, metadata, and pipeline · #38449
Fixed generated names exceeding database limits and restored logical-name recovery across SQL rewriting, metadata refresh, and pipeline paths. Preserved existing names that fit. Scope: 36 files, including tests.
Same value, different shard · Opt-in routing feature · #38327
Added HASH_MOD normalization so equal signed 32-bit integer values route consistently across Integer, Long, and BigInteger. Kept legacy routing as the default for upgrade compatibility.
Missing failure notification before compatibility fallback · Reliability fix · Issue #39763 → Merged PR #39764
While auditing execution hooks for RouteContract, fixed a missing SQL failure notification before a compatibility fallback. Regression tests verify preserved return values and exactly one failure notification in trunk and worker paths.

Implementation, tests, and maintainer review
Java library author · v0.1.4 on Maven Central
Detects execution changes that result assertions miss. In a controlled MySQL example, the query result stays unchanged while observed JDBC execution attempts increase 1 → 2. RouteContract rejects the change against a reviewed baseline in CI.
Checks execution budgets, data sources, and rewritten SQL; generates Markdown/JSON review reports. The public release was verified across Java 17/21 × Gradle/Maven.
