fix: use UUIDs and cleanup in beacon styles example to avoid stale item collisions#2125
Conversation
…em collisions - Generate unique work_id UUIDs per run instead of hardcoded "1" and "2" - Add temporary work_id IN filter to scans (to be removed after table cleanup) - Delete items in finally/cleanup block after assertions - Dynamic compound beacon value using UUID instead of hardcoded "I-1.T-small" - Applied to both Rust and Java examples

## [4.0.0](v3.9.0-java...v4.0.0-java) (2026-04-29) ### ⚠ BREAKING CHANGES * **java:** add DDBEC with SDK v2 and remove DDBEC with SDK V1 (#2048) * The AWS Database Encryption SDK for DynamoDB will NOT support AWS SDK for Java 1.x in the embedded 2.x version (which was known as DynamoDB Encryption Client(DDBEC)). The embedded DDBEC will now use AWS SDK for Java 2.x. These changes are limited to embedded DDBEC and rest of DB-ESDK has no code changes. * If consumer of DB-ESDK is using APIs from namespace `com.amazonaws.services.dynamodbv2` through DB-ESDK then they have to migrate to use corresponding API from namespace `com.amazonaws.services.dynamodbv2.datamodeling.sdkv2`. If consumer of DB-ESDK are NOT using namespace `com.amazonaws.services.dynamodbv2` through DB-ESDK then there will not be any breaking change when moving to next major version. ### Features -- Java * **java:** add DDBEC with SDK v2 and remove DDBEC with SDK V1 ([#2048](#2048)) ([035dbe3](035dbe3)) ### Fixes -- All Languages * use UUIDs and cleanup in beacon styles example to avoid stale item collisions ([#2125](#2125)) ([773c1ff](773c1ff)) ### Fixes -- Java * **java:** drop hkdf offset method ([#2011](#2011)) ([b8f29f9](b8f29f9)) ### Maintenance -- All Languages * **dafny:** bump MPL and update mutable map ([#1974](#1974)) ([e9ea870](e9ea870)) * **dafny:** bump smithy dafny ([#1971](#1971)) ([85309a0](85309a0)) ### Maintenance -- Java * **java:** Allow local testing ([#1947](#1947)) ([bf5a106](bf5a106)) * **java:** Attempt to reduce flaky CI ([#2220](#2220)) ([987aec6](987aec6)) * **java:** attempt to reduce flaky CI failures ([#2203](#2203)) ([b4d88f1](b4d88f1)) * **java:** bring back test against released MPL version ([#2226](#2226)) ([a340b34](a340b34)) * **java:** fix GetEncryptedDataKeyDescription java Example ([#1973](#1973)) ([ba8fcb7](ba8fcb7)) * **java:** retry failed workflow ([#2229](#2229)) ([2668d68](2668d68)) * **java:** shut down local DDB in test ([#2176](#2176)) ([fa1e151](fa1e151))

Problem
The beacon styles searchable encryption example uses hardcoded
work_idvalues ("1"and"2"), causing scan assertions to fail when stale items from previous runs (encrypted with different branch keys) exist in the shared DDB table.Fix
work_idvalues per runwork_id IN (:wid1, :wid2)filter to all scans (TODO: remove after table cleanup)"I-1.T-small"Changes
