Compatibility analysis

Dependency: AWS SDK for Java v2, managed by aws.sdk.v2.version, upgraded from 2.55.5 to 2.55.6. The complete direct published release path reviewed in ROUND_1 is 2.55.5 -> 2.55.6, with no intervening published release. The carried-forward ROUND_1 verdict is SAFE. API/ABI, runtime, configuration, serialization/wire, persistence, and clients are SAFE: the patch-level target preserves the Druid-consumed AWS SDK contracts and does not change Druid APIs, options, wire formats, or persisted data. Transitive dependencies are SAFE under the resolved AWS SDK v2 set and its existing dependency-management constraints. Licenses are SAFE after the bounded licenses.yaml repair added the 11 missing 2.55.6 target-artifact entries while preserving the existing AWS SDK Apache 2.0 metadata. Extension/plugin SPI behavior is SAFE: no Druid extension registration, plugin contract, or SPI implementation changed. No CONCERN, INCOMPATIBLE, or UNRESOLVED Druid-relevant evidence was found in the inherited ROUND_1 review.

Druid impact

The dependency version change is in the root pom.xml; the bounded CI metadata repair is in licenses.yaml. The managed AWS SDK modules are consumed by Druid AWS integrations, including the S3 extension's S3, STS, and transfer clients and related dependency-managed modules. No tracked production or test source changed, so there is no source-level behavior change; the practical effect is dependency resolution at AWS SDK 2.55.6 plus complete license metadata for the resolved artifacts.

Validation

• Reused the persisted ROUND_1 release evidence and all nine-category SAFE findings; no compatibility research was repeated in this CI-only round.
• Inspected the complete PR diff, base/head commits, affected POM and license metadata, AWS SDK dependency consumers, and the isolated worktree.
• Dependency resolution and bounded license validation passed after the 11-entry licenses.yaml repair; git diff --check passed.
• No tracked production/test source changed and no additional local source test was required; exact-head GitHub CI supplied the full validation.
• The earlier PR-caused packaging failure was resolved by the license metadata repair. The later external HttpEmitterEventCollectorTest timeout was diagnosed from the failed job log and resolved by the targeted rerun.

CI gate

Exact current head: dba1e975004b94e274d73039d74ed86787419a53. The PR is OPEN, non-draft, MERGEABLE, and CLEAN. The authoritative complete statusCheckRollup is SUCCESS: workflow 38020130276, attempt 2, has 27/27 CheckRuns completed with SUCCESS and 0 StatusContexts reported (0 successful). Every reported item succeeded. The targeted rerun of job 114127509008 succeeded after the external HttpEmitterEventCollectorTest timeout; no failed, active, skipped, neutral, or unknown result remains.

Automation actions

The automation changed licenses.yaml to add the 11 missing AWS SDK 2.55.6 license entries, pushed commit dba1e975004b94e274d73039d74ed86787419a53, and performed the eligible targeted rerun of workflow 38020130276 attempt 2, job 114127509008. No tracked production or test source was changed, no further repair or rerun is needed, and this approval body is prepared for the coordinator's reserved approval action. No merge was performed.
