Verification scripts (2026-09-11, REPORT.md section 17)

Run the Python scripts from a worker (spark2), never on the head; memguard.py and the ramp drivers run on the head.

• memguard.py <log> [threshold_gb] (head): samples MemAvailable every second, POSTs /abort_request below the threshold. Arm it for every long-prompt test; stop it after.
• batchtest.py <tag>: greedy batches of 3 and 4 plus a sampled batch of 4 (prose, 120 tokens); flags symbol/CJK garbage. The NaN-prefill fault of section 17 shows here.
• diag5.py: virgin-engine probe (600- and 150-token prompts, batches of 3 and 4), then a replay of the boot.py warm-up pieces with a probe after each, then a length sweep.
• prefill_distinct.py <tokens> <seed>: one needle prompt of ~tokens with seeded content (no radix hits). ramp2.sh <tokens> <seed...> (head) runs several under the guard and reports MemAvailable before / lowest / after.
• throughput.py: greedy and sampled throughput at concurrency 1-4 (usage-based).
• idle_drift.sh (head): MemAvailable every 30 s for 10 minutes.
