From 6e4a57522173729181f49722f01c65c0dd740d8a Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sun, 17 May 2026 18:01:55 +0300 Subject: [PATCH] [AZ-440] [AZ-441] [AZ-442] [AZ-443] NFT-LIM-01/02/03+05/04 blackbox scenarios MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Batch 88 — adds four resource-limit blackbox scenarios + pure-logic helpers + unit tests: - NFT-LIM-01 Jetson memory (AC-NEW-13): tier2_only; Plan A/B budgets; AC-4 OOM-event scan; 30 s warm-up window; VmRSS + tegrastats streams. - NFT-LIM-02 FDR size (AC-7.3): 30 min → 8 h linear extrapolation against 50 GiB; ±60 s replay-window slack for AC-1. - NFT-LIM-03+05 storage (AC-7.4 + AC-NEW-12 + RESTRICT-STORAGE): aggregate ≤ 100 GiB across tile-cache + tile-cache-write + fdr-output; thumbnail-log < 1 GiB strict 8 h-extrapolated. - NFT-LIM-04 thermal (AC-NEW-5 PARTIAL): tier2_only; CPU/SoC p99 ≤ T_throttle − 5 °C; throttle-event scan; PARTIAL annotation written to traceability-status.json. Thresholds fixture lives at e2e/fixtures/jetson/thermal-thresholds.json (moved from the task spec's suggested tests/fixtures/ path so the file stays inside the blackbox_tests Owns: e2e/** envelope). All four helpers are public-boundary-only (no src/gps_denied_onboard imports). Scenarios skip cleanly in the Tier-1 docker harness pending AZ-595 (SITL replay builder) for the four shared fixture inputs and AZ-444 (Tier-2 Jetson runner) for the tier2_only scenarios. Code review: PASS_WITH_WARNINGS (0/0/2/1). Both Mediums are carried-over write_csv_evidence + _resolve_fixture_path duplication, deferred to AZ-446 (batch 89). Low is the self-resolved AZ-443 fixture ownership drift documented in the review. Tests: 1223 e2e/_unit_tests passing (+1 vs. batch 87 from the new directory-layout entry); 24 resource_limit scenarios collect and skip cleanly under runner/pytest.ini.
