[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.

+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|----------------|-------|-------------|--------|
+| AZ-440_nft_lim_01_jetson_memory | Done | 3 (helper, scenario, unit test) | pass (skip on tier1-docker) | 6/6 | None |

+
+## AC Test Coverage: All covered (17 of 17 ACs across the batch)
+
+## Code Review Verdict: PASS_WITH_WARNINGS
+
+See `_docs/03_implementation/reviews/batch_88_review.md`. 0 Critical / 0 High / 2 Medium (both carried-over CSV-writer + fixture-resolver duplication, deferred to AZ-446) / 1 Low (self-resolved task-spec path drift for AZ-443's thermal-thresholds fixture).
+
+## Auto-Fix Attempts: 0
+
+No FAIL findings. The F3 Low finding was resolved in-batch (fixture moved into `e2e/fixtures/jetson/` and the task spec footnoted) without re-running the review.
+
+## Stuck Agents: None
+
+## Test Results
+
+- 4 helper unit-test modules → 207 unit tests pass locally in 0.36 s
+  (`e2e/_unit_tests/helpers/test_*_evaluator.py`).
+- Full e2e unit-test suite: **1223 passed in 154 s**
+  (`e2e/_unit_tests/`).
+- 24 resource_limit scenarios collect cleanly and skip cleanly in the
+  Tier-1 docker harness:
+  - 12 SKIP on `tier2_only` (NFT-LIM-01, NFT-LIM-04 — Tier-2 only).
+  - 8 SKIP on `sitl_replay_ready` (NFT-LIM-02, NFT-LIM-03+05 — pending
+    AZ-595 fixture).
+  - 4 SKIP on `vins_mono` research-build-only guard (per D-C1-1-SUB-A).
+
+## Production Dependencies Surfaced
+
+- **AZ-595** (SITL replay builder) — per-second VmRSS + tegrastats memory
+  samples, per-second tegrastats temperature samples, per-minute
+  `du -sh` snapshots for `fdr-output`, `tile-cache`, `tile-cache-write`,
+  `thumbnail-log`, and runner-projected `dmesg` lines (OOM + thermal
+  throttle). Fixture filenames per scenario docstring; all 4 scenarios
+  block on `sitl_replay_ready` until AZ-595 lands.
+- **AZ-444** (Tier-2 Jetson runner) — already required for AC-1
+  tier-guard skip-gating on tier1-docker. AC-1 enforced via
+  `@pytest.mark.tier2_only` for NFT-LIM-01 + NFT-LIM-04.
+
+## Next Batch: 89 — AZ-446 (CSV reporter refinements, 2 points). Also picks up the F1+F2 cumulative-review carry-overs as natural scope.

+
+## 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.
