Oleksandr Bezdieniezhnykh 6e4a575221 [AZ-440] [AZ-441] [AZ-442] [AZ-443] NFT-LIM-01/02/03+05/04 blackbox scenarios 
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.

Code Review Report

Batch: 88 — AZ-440, AZ-441, AZ-442, AZ-443 (NFT-LIM-01/02/03+05/04) Date: 2026-05-17 Verdict: PASS_WITH_WARNINGS

  • e2e/tests/resource_limit/__init__.py (docstring only)
  • e2e/_unit_tests/test_directory_layout.py (added 8 new paths + 1 fixture path)
  • _docs/02_tasks/todo/AZ-443_nft_lim_04_thermal.md (constraint path corrected to reflect ownership — see F1)

Findings

# Severity Category File:Line Title
1 Medium Maintainability e2e/runner/helpers/*_evaluator.py Duplicated write_csv_evidence boilerplate (carried over from batches 85–87)
2 Medium Maintainability e2e/tests/resource_limit/test_nft_lim_0[1-4]*.py Duplicated _resolve_fixture_path boilerplate (carried over from batches 85–87)
3 Low Scope _docs/02_tasks/todo/AZ-443_nft_lim_04_thermal.md:61 Task spec referenced tests/fixtures/ for the thresholds fixture, which is outside the blackbox_tests Owns: e2e/** envelope — implementation moved to e2e/fixtures/jetson/thermal-thresholds.json; spec note added inline

No Critical, High, or Security findings.

Finding Details

F1: Duplicated write_csv_evidence boilerplate (Medium / Maintainability)

  • Location: e2e/runner/helpers/memory_budget_evaluator.py, fdr_size_evaluator.py, storage_budget_evaluator.py, thermal_envelope_evaluator.py.
  • Description: each helper hand-rolls the same single-row CSV pattern (open → writerow(header) → writerow(values)) and the empty-cell convention ("" if value is None else value). Same observation raised in cumulative_review_batches_85_87.md for prior helpers (egress_observer, mavlink_signing_evaluator, etc.).
  • Suggestion: keep the duplication for now; AZ-446 (CSV reporter refinements, scheduled batch 89) will consolidate the pattern into a reusable helper. Tracking via the existing PBI rather than expanding Batch 88 scope.
  • Tasks: AZ-440, AZ-441, AZ-442, AZ-443.

F2: Duplicated _resolve_fixture_path boilerplate (Medium / Maintainability)

  • Location: e2e/tests/resource_limit/test_nft_lim_01_jetson_memory.py:135, test_nft_lim_02_fdr_size.py, test_nft_lim_03_05_storage_budget.py, similar branch in test_nft_lim_04_thermal.py:135.
  • Description: each scenario re-implements the same env-var → relative path → sitl_observer.replay_dir() resolution. Carried over from the cumulative review of batches 85–87.
  • Suggestion: extract into runner/helpers/sitl_observer (or a new runner.helpers.fixture_resolver) as part of AZ-446 / the cumulative-review remediation PBI.
  • Tasks: AZ-440, AZ-441, AZ-442, AZ-443.

F3: Task spec fixture path violated ownership (Low / Scope)

  • Location: _docs/02_tasks/todo/AZ-443_nft_lim_04_thermal.md:61.
  • Description: the constraint section suggested placing the thermal thresholds fixture at tests/fixtures/jetson-thermal-thresholds.json. That path is outside the blackbox_tests component's Owns: e2e/** glob (module-layout.md:424), and the only consumer is the e2e test harness.
  • Resolution: implementation lives at e2e/fixtures/jetson/thermal-thresholds.json; task spec updated in the same batch with an explicit deviation note (see commit).
  • Tasks: AZ-443.

AC Test Coverage

Task ACs Coverage
AZ-440 NFT-LIM-01 AC-1..AC-6 All covered — AC-1 via tier2_only; AC-2/3/4 via MemoryBudgetReport.passes_* + assertion; AC-5 via _resolve_plan() + Plan.PLAN_B unit test; AC-6 via conftest parameterization.
AZ-441 NFT-LIM-02 AC-1..AC-3 All covered — AC-1 via passes_replay_window (±60 s slack); AC-2 via passes_extrapolation; AC-3 via conftest parameterization.
AZ-442 NFT-LIM-03+05 AC-1..AC-3 All covered — AC-1 via passes_aggregate; AC-2 via strict-< passes_thumbnail_log; AC-3 via conftest parameterization.
AZ-443 NFT-LIM-04 AC-1..AC-5 All covered — AC-1 via tier2_only; AC-2 via passes_no_throttle; AC-3 via passes_headroom + ThermalThresholds.load_from_fixture; AC-4 via write_traceability_partial_annotation; AC-5 via conftest parameterization.

Verdict Logic

  • Critical findings: 0
  • High findings: 0
  • Medium findings: 2 (both carried-over)
  • Low findings: 1 (self-resolved in batch)

→ PASS_WITH_WARNINGS

Architecture Compliance (Phase 7)

  • All new product files live under e2e/** (owned by blackbox_tests).
  • No src/gps_denied_onboard imports (docstrings explicit; verified by grep).
  • No new cyclic dependencies; helpers are leaf-level modules importing only csv, json, pathlib, dataclasses, enum, math.
  • F3 was an ownership drift that has been corrected in-batch; no carried-over architecture findings.
