+Usage:
+  scripts/manual_transition_failure_samples.sh --endpoint <admin-api> --sample <label:job-id[:expected_reason]> [options]
+
+Required for real runs:
+  --endpoint              Admin endpoint base, e.g. https://127.0.0.1:9000
+  --sample                Failure sample spec. Repeatable. Example: auth:<job-id>:RemoteAuth
+
+Optional:
+  --admin-token           Bearer token for /admin/v3 endpoints
+  --log-glob              Log glob to scan, default /var/log/rustfs/*.log
+  --metric-types          /admin/v3/metrics type flags, default 1
+  --metric-samples        /admin/v3/metrics sample count, default 1
+  --metric-interval       /admin/v3/metrics interval query param
+  --bucket                Optional bucket filter for focused log output
+  --min-distinct-reasons  Minimum distinct tier failure reasons required, default 2
+  --out-dir               Artifact output dir
+  --dry-run               Generate the sample command template without admin calls
+  --help                  Show usage
+
+Output:
+  - failure_attribution_summary.csv
+  - sample_plan.md
+  - commands.txt
+  - per-sample job_status.json, metrics.json, and log_events.json

+Use this artifact to turn #1509 auth/network/timeout checks into repeatable evidence.
+
+## Prepare controlled samples
+
+- auth: configure a temporary remote tier with invalid credentials, run one async manual transition, keep the returned job_id
+- network: configure a temporary remote tier endpoint that is unreachable or refuses connections, run one async manual transition, keep the returned job_id
+- timeout: configure a throttled or blackholed remote tier endpoint with a short client timeout, run one async manual transition, keep the returned job_id
+
+## Capture evidence
+
+Replace the placeholders and run:
+
+```bash
+scripts/manual_transition_failure_samples.sh \
+  --endpoint <admin-api> \
+  --admin-token "$TOKEN" \
+  --sample auth:<JOB_ID_AUTH>:<expected_reason_key> \
+  --sample network:<JOB_ID_NETWORK>:<expected_reason_key> \
+  --sample timeout:<JOB_ID_TIMEOUT>:<expected_reason_key> \
+  --min-distinct-reasons 2 \
+  --out-dir target/manual-transition-failure-samples/<run-id>
+```
+
+## Close gate
+
+- at least two samples have `matched_expected_reason=true`
+- `distinct_reason_count` across all samples is greater than or equal to `--min-distinct-reasons`
+- no status/log artifact exposes secrets or full credential material
+- terminal partial/failed counts agree with `tier_failure_by_reason`
