PR-added test — GREEN

Job	Status
Stateless tests (amd_asan, distributed plan, parallel, 4/4)	OK
Stateless tests (amd_debug, distributed plan, s3 storage, parallel)	OK
Stateless tests (amd_debug, parallel)	OK
Stateless tests (arm_asan, azure, parallel, 4/4)	OK

Fast test	SKIPPED (expected, Tags: no-fasttest)

The MV-over-Iceberg crash path has clean positive coverage.

CI overview (head commit)

• PR test workflow: 42 success / 51 skipped / 3 failure
• Regression workflow: 30 success / 66 skipped / 4 failure (chronic baseline)
• One pending action_required job (queue/auth)

PR test-workflow failures

Check	Verdict
Integration tests (amd_asan, db disk, old analyzer, 3/6) — 24 × test_s3_cluster/test.py::*	Cascade failure (all 24 fail at the same timestamp). Same pattern recurs across antalya-26.3 PRs 1773, 1767, 1757, 1741, 1731, 1692 in last 30 days. PR diff is in StorageMaterializedView, not s3Cluster — not PR-caused.
Stateless tests (amd_debug, sequential) — 00157_cache_dictionary	Pre-existing flake (78 fails / 25 PRs in 30d). Unrelated.
Stateless tests (arm_asan, azure, sequential, 2/2) — 03443_shared_storage_snapshots	Pre-existing flake (29 fails / 17 PRs in 30d). Unrelated.

Regression-workflow failures (chronic baseline on antalya-26.3)

Suite	Fails
Swarms (Aarch64 + Release)	226
Parquet (Aarch64 + Release)	34
S3Export partition (Aarch64 + Release)	20
S3Export part (Aarch64 + Release)	14

Same fingerprint as sibling antalya-26.3 PRs (1771, 1770, 1769, 1767, 1759, …). No new failure modes.

Caveat — partial frontport

This PR lands on antalya-26.3 while companion features from antalya-26.1 are still being frontported in parallel. Final re-verify recommended once the rest of the bundle lands.

Verdict

Safe to merge.

• PR’s new test 04077_iceberg_mv_select_crash passes 100% (6/6 stateless runs).
• Test-level failures are all well-known pre-existing flakes (00157_cache_dictionary, 03443_shared_storage_snapshots) or the recurring test_s3_cluster cascade.
• Regression failures match the chronic antalya-26.3 baseline.
