# Traceability Matrix

Authored by `/test-spec` Phase 2 (2026-05-19).

This matrix maps every acceptance-criterion bullet from `_docs/00_problem/acceptance_criteria.md` and every restriction bullet from `_docs/00_problem/restrictions.md` to the test scenarios that exercise them. Coverage is **scenario-level**, not fixture-level — scenarios marked `DEFERRED` in the underlying `*-tests.md` files still count as covered for the purpose of "the test is specified"; the fixture-acquisition status is tracked separately in `_docs/_process_leftovers/2026-05-19_autopilot_test_fixtures.md`.

## Coverage Summary

| Category | Total Items | Covered | Partially Covered | Not Covered | Coverage % (counting Partially as 0.5) |
|---|---|---|---|---|---|
| Acceptance Criteria | 47 | 43 | 1 | 3 | (43 + 0.5×1) / 47 ≈ **92.6 %** |
| Restrictions | 30 | 25 | 2 | 3 | (25 + 0.5×2) / 30 ≈ **86.7 %** |
| **Total** | 77 | 68 | 3 | 6 | **(68 + 1.5) / 77 ≈ 90.3 %** |

(Coverage here is "test scenario exists for the item", not "fixture has been acquired and the test currently passes". Fixture status is tracked in `_docs/_process_leftovers/2026-05-19_autopilot_test_fixtures.md`.)

## Uncovered Items Analysis

| § | Item | Reason not covered | Risk | Mitigation |
|---|---|---|---|---|
| §1 | AC-Scan-SweepCoverage (wide-area sweep covers planned route) | The "covers the planned route" property is a path-coverage assertion best tested by component-level tests in the `scan_controller` component (geometry coverage) rather than at the blackbox level | Medium — incorrect sweep pattern leaks observation gaps | Componenet-test in `scan_controller` (added by `/decompose` test tasks); a Tier-E "did the camera point at every planned waypoint area for ≥ N seconds" scenario can be added if needed |
| §2 | AC-Gate-SeasonCoverage / AC-Q-SeasonGates | Per-season coverage gates depend on dataset acquisition owned by `../ai-training` and per-season flight tests (Q13) | High — model performance on un-evaluated seasons unknown | Tracked as release-gate item; D3/D4/D5/D1 scenarios DEFERRED until each season's dataset lands |
| §3 | AC-Gate-MavlinkSITLConformance / RESTRICT-Rel-MavlinkConformance | A dedicated "every command in `architecture.md §7.7` exercised against SITL" suite is recommended in addition to the implicit coverage by R-scenarios | Medium — could miss a rarely-used command | Add a `NFT-MavlinkConformance` suite during Step 9 (Decompose Tests) — explicit per-command SITL exercise |
| §4 | RESTRICT-HW-Z40K (Z40K compatibility) | Requires a second camera HW for the swap test | Medium — could miss a A40-specific assumption | Run the Tier-HW rows on Z40K as a post-MVP smoke step |
| §5 | RESTRICT-SW-FP16 (model precision) | Pinned at config + model-loading layer; not externally observable beyond perf/latency | Low — incorrect precision would manifest as either L1 latency or D2 regression failure | Add a startup log assertion: "Tier 2/3 models loaded with precision=FP16" via the SUT's structured boot log |
| §6 | RESTRICT-Rel-AirframeLossRedImmediate (immediate red on airframe link loss) | NFT-RES-R7 asserts red after retry exhaustion; the "immediate red on link loss" path (no retries) is implicit | Low–Medium — depends on timing window between "link silent" and "considered lost" | Add `NFT-RES-AirframeImmediate` scenario in Step 9 (Decompose Tests) — sustained zero MAVLink traffic for N seconds → immediate health red (no retry phase) |

## Scenario index by file

| File | Scenarios | Read-back ID prefix |

## Open dependencies summary

| Dependency | Affects (scenario count) | Tracking |
|---|---|---|
| `<DEFERRED: gimbal.csv + telemetry.csv pairs>` | FT-P-007/008/009/010, NFT-PERF-L6/L7 | Leftover row "Gimbal CSV pairs" |

| `<DEFERRED: HW Jetson Orin Nano Super OR benchmarked replay>` | every Tier-HW scenario (L1, L2, L4, L5, L8, Re1, Re2, CPU, GPU) | Leftover does not enumerate HW directly — tracked via the project-level Acceptance Gate |
| `<DEFERRED: Q6 — MAVLink-2 signing decision>` | NFT-SEC-MavlinkUnsigned | architecture.md §8 Q6 |

When any of the above dependencies resolves, the corresponding leftover entry is replayed (per `tracker.mdc → Leftovers Mechanism`) and the affected scenarios' `Test status` lines move from `DEFERRED` to `READY` in the source files.

## Phase 3 — Test Data & Expected Results Validation Gate Outcome

Recorded by `/test-spec` Phase 3 on 2026-05-19.

### Mechanical gate

Phase 3's mechanical contract is: every scenario MUST have either (a) a provided input + provided quantifiable expected result, OR (b) a behavioural trigger + observable behaviour + quantifiable pass/fail criterion. Scenarios that fail this contract are normally REMOVED. The 75 % final-coverage check then applies.

| Shape | Total scenarios | Quantifiable comparison declared | Input/trigger fully provided today | Input/trigger DEFERRED (release-gate item) |
|---|---|---|---|---|
| Input/output | 56 | 56 | 16 | 40 |
| Behavioural | 10 | 10 | 10 | 0 |
| **Total** | **66** | **66 (100 %)** | **26 (39 %)** | **40 (61 %)** |

Every scenario carries a `Comparison` method drawn from `.cursor/skills/test-spec/templates/expected-results.md` (`exact`, `numeric_tolerance`, `threshold_min/max`, `range`, `regex`, `substring`, `set_contains`, `json_diff`, `schema_match`, `file_reference`) — none of the 66 fail the quantifiability check.

### Project-policy override (recorded 2026-05-19)

The Phase 3 75 % fixture-coverage gate is **intentionally overridden** for this project, per the decision recorded in `_docs/00_problem/input_data/expected_results/results_report.md → "Decision (project policy)"`:

> rather than block on the Phase 3 75 % gate, each deferred row is now registered with a structured `<DEFERRED:>` tag and surfaces in `data_parameters.md → "Gaps that block /test-spec downstream"`. `/test-spec` Phase 2 can author scenarios for all 56 rows; deferred rows become **release-gate items**, not development-gate items. The `acceptance_criteria.md → "Acceptance Gates (project-level)"` hardware/replay benchmark requirement is preserved as the hard release gate — that one is NOT being deferred.

Under this policy:

- **No scenarios are removed by Phase 3.** Every authored scenario remains in the spec; its `Test status` line in the source file (`blackbox-tests.md`, `performance-tests.md`, etc.) carries either `READY` or `DEFERRED — <reason>`.
- **Final coverage** is computed at the **scenario level**, not the fixture level. Per the matrix above:
  - AC coverage: 92.6 % (43 + 0.5 × 1 / 47)
  - RESTRICT coverage: 86.7 % (25 + 0.5 × 2 / 30)
  - **Total: 90.3 %** — well above the 75 % gate.
- **Fixture acquisition** is tracked as a release-gate concern in `_docs/_process_leftovers/2026-05-19_autopilot_test_fixtures.md`; on every `/autodev` invocation the leftover-replay step re-evaluates whether any deferred fixture has landed and moves the affected scenarios from `DEFERRED` to `READY`.
- **The project-level Acceptance Gate** (`acceptance_criteria.md → "Acceptance Gates"` — HW/replay benchmark, per-season coverage, MAVLink SITL conformance) remains a hard release blocker. The override does NOT relax that gate.

### Phase 3 verdict

**PASSED** — scenario-level coverage 90.3 % ≥ 75 % gate; every scenario has a quantifiable comparison; deferred-fixture tracking handled via leftovers replay; no scenarios removed.

## Phase 4 — Test Runner Script Generation: SKIPPED in this invocation

Per `phases/04-runner-scripts.md → "Skip condition"`:

> If this skill was invoked from the `/plan` skill (planning context, no code exists yet), skip Phase 4 entirely. Script creation should instead be planned as a task during decompose — the decomposer creates a task for creating these scripts. Phase 4 only runs when invoked from the existing-code flow (where source code already exists) or standalone.

This invocation is greenfield Step 5 (Test Spec) and no source code exists yet — the `_docs/02_document/components/*/description.md` files describe 13 Rust components that the Implement step (Step 7) will create. Producing runner scripts here would write `scripts/run-tests.sh` and `scripts/run-performance-tests.sh` against a binary that does not yet exist.

**Handoff to Step 6 (Decompose)**: the decomposer MUST create at least two task specs covering the test runner scripts:

1. A task to create `scripts/run-tests.sh` (Tier B/E orchestration; calls `docker compose -f e2e/docker-compose.autopilot-e2e.yml up` and runs `cargo test --release --test scenarios` in `e2e-consumer`).
2. A task to create `scripts/run-performance-tests.sh` (Tier HW orchestration; per `environment.md → Hardware Execution Matrix`).

Both tasks should be tagged as part of the test-infrastructure decomposition (`Step 1t` of decompose tests-only mode) so they land before any Tier-B test scenarios are implemented.
