This short report brings to light some interesting commits to [scylla-cluster-tests.git master](https://github.com/scylladb/scylla-cluster-tests) from the last week. Commits in the fa58b5b1…6855a9fa range are covered.

There were 35 non-merge commits from 12 authors in that period. Some notable commits:

Added AWS [region fallback on capacity exhaustion](https://github.com/scylladb/scylla-cluster-tests/commit/ba9fc0c683ade7119547926af298ec3267ce64dc): when a region runs out of capacity during provisioning, SCT now relocates the whole cluster to the next eligible region instead of failing. The [multi-DC variant](https://github.com/scylladb/scylla-cluster-tests/commit/4599f4f0cad30b3202edfdcf6051a12e22d5dd5f) relocates only the exhausted DC while healthy DCs stay in place, and the feature was subsequently [enabled by default](https://github.com/scylladb/scylla-cluster-tests/commit/91ea16c45752a64764fda27f0573cd3095c421b7).

A new [implementation plan for feature-aware adaptive topology timeouts](https://github.com/scylladb/scylla-cluster-tests/commit/22e20b887a0ce034b7ccb26b20340a35f03963ba) was registered, proposing schema-based detection of MV, SI, CDC, and LWT so decommission, new-node, and tablet-migration operations get larger (up to 3x) time budgets when those features are enabled, with Argus telemetry for post-failure diagnosis.

The [scylla-doctor bump to v1.12](https://github.com/scylladb/scylla-cluster-tests/commit/824aa83f61fc810346c4aed9da06b4179e6d4279) (from 1.10) brings several new collectors and analyzers — large-partitions/cells/rows and role-permissions collectors, STCS-in-schema and keyspace-replication analyzers — plus aarch64 support across the architecture, clock-source, and instruction-set analyzers and coverage for newer AWS instance types (i7i/i7ie/i8g/i8ge).

On the infrastructure side, the [SCT runner base image was bumped to Ubuntu 26.04](https://github.com/scylladb/scylla-cluster-tests/commit/91e16755fca972b752035d6db6881b1b4785886b). The cloud catalog also [dropped Azure Dpdsv5](https://github.com/scylladb/scylla-cluster-tests/commit/73e82f673b5c7d4e7d09b200bfe67d5f05d79864) from pricing/sizing since it has no local NVMe disk that scylla-machine-image can use.

Backport automation migrated to the [shared github-automation reusable workflow](https://github.com/scylladb/scylla-cluster-tests/commit/79e2473bed124be5931ebba909e3b59660237b36) used by scylla-pkg, scylla-dtest, and scylla-machine-image — backports now target `branch-X.Y` directly and run in parallel by default, with a later pin bump enabling a [`cascade_backport` opt-out label](https://github.com/scylladb/scylla-cluster-tests/commit/20a3a25a69e09f768c1a5406266a4dadc1f7858c) for chained backports.

Argus integration gained an [always-on request replay log](https://github.com/scylladb/scylla-cluster-tests/commit/6855a9faa95cc2da098a671d25218d386b11506d): every mutating Argus API call is now journaled to JSONL so it can be replayed later in case of Argus downtime or issues. Brought also new `hydra investigate download-logs` subcommand.

See you in the next issue of last week in scylla-cluster-tests.git master!
