# Dependencies Table **Date**: 2026-05-13 (refreshed after AZ-507 + AZ-508 hygiene-PBI onboarding from cumulative review batches 31-33; previously 2026-05-11 for AZ-489 + AZ-490 ADR-010 operator-origin path) **Total Tasks**: 144 (103 product + 41 blackbox-test) **Total Complexity Points**: 482 (349 product + 133 blackbox-test) Dependencies columns list only the tracker-ID portion (descriptive tail text in each task spec is omitted here for table-readability). The authoritative dependency narrative — including "co-developed", "forward dependency", and helper-vs-Protocol distinctions — lives in each task's own `Dependencies:` field. The graph is a strict DAG: a topological traversal visits all 142 tasks. The 15 forward edges (dep ID > task ID) are all declared and documented below under **Cycle Check**. | Task | Name | Complexity | Dependencies | Epic |

Both tasks ship together; the bridge ships against the published schema contract once AZ-272 is stable. This is the ONLY forward dependency in the plan — verified by inspection. - **C4 ↔ C5 co-development (ADR-003)**: AZ-358 depends on AZ-381's concrete `ISam2GraphHandle`; AZ-383 depends on AZ-358's `PoseEstimate.covariance_mode`. Both tasks ship in lockstep — the shared `ISam2GraphHandle` Protocol stub is owned by AZ-355, the concrete impl by AZ-381. - **C5 ↔ C8 co-development**: AZ-385 depends on C8 `GpsHealth` (AZ-391) and `QgcTelemetryAdapter` (AZ-397); AZ-388 depends on AZ-390 / AZ-397; AZ-396 depends on AZ-385. Each side ships against the AZ-390 Protocol contract until the consumer task lands. - **AZ-401 (compose_replay)** intentionally depends on the C1–C5 epic IDs (AZ-254 … AZ-260) at the documentation level — concrete strategy task IDs flow in through each component's composition factory, not through this composition root directly. - **E-BBT (AZ-262) forward dependencies on AZ-444 (Tier-2 harness)**: AZ-428, AZ-430, AZ-440, AZ-443 declare hard forward deps on AZ-444; AZ-439 declares an optional forward dep on AZ-444 (Tier-2 ASan-fuzz variant). These tasks ship in a tight loop with AZ-444 — the harness must exist before any Tier-2 NFT scenario can run. Tier-1 sub-cases of NFT-PERF-02, NFT-RES-*, NFT-SEC-*, NFT-LIM-02, NFT-LIM-03 do not require AZ-444 and remain independently runnable. - **E-BBT scenario chains within AZ-262**: - AZ-413 (FT-P-05+06) depends on AZ-412 (FT-P-04) — FT-P-06 is a piggyback assertion over FT-P-04 + FT-P-05 evidence. - AZ-435 (NFT-RES-04) depends on AZ-426 (FT-N-04) — both consume `blackout_spoof.py`; NFT-RES-04 is the focused 35 s escalation scenario while FT-N-04 covers the 5 s / 15 s / 35 s ladder. - AZ-446 depends on AZ-445 — refinements layer over the bundler. - **ADR-010 operator-origin path** (added 2026-05-11): - **AZ-489 (C12 FlightsApiClient)** is the new read-only Flight resolver for C12; it has no consumers inside its own epic but feeds AZ-326 (CLI flags) and AZ-328 (orchestrator phase 0) — both declare a hard backward dep on AZ-489. The CLI's `--flight-id` / `--flight-file` flags + AZ-328's flight-resolve phase 0 cannot land without it. - **AZ-490 (C5 set_takeoff_origin)** extends the AZ-381 Protocol with the pre-takeoff entrypoint, amends the AZ-385 source-label state machine with the third bounded-delta clause, and depends on AZ-381..AZ-386 (Protocol + factor adds + marginals + source label gate + ESKF baseline) plus AZ-272/273/279 for FDR + Vincenty. All deps are backward; AZ-490 ships after the C5 epic core lands. - **AZ-419 (FT-P-11 cold-start)** carries forward deps on both AZ-489 + AZ-490 — the blackbox cold-start scenario now exercises the operator-manifest primary path (needs both) AND the FC EKF secondary fallback (back-compat). - **All E-BBT tasks depend on AZ-406 (test infrastructure)**; this is by design — AZ-406 is the foundation every blackbox test depends on (analogous to AZ-263 for the product side). - **Hygiene PBIs from cumulative review batches 31-33** (added 2026-05-13): - **AZ-507** (E-CC-CONF / AZ-246) — module-layout.md ↔ AZ-270 lint alignment. Depends on AZ-263 (structure), AZ-270 (the lint test + composition root), and AZ-321 (the engine_compiler whose `except Exception` is narrowed). All deps are backward and completed; AZ-507 can land in any future batch. NOT a gate on AZ-322 / AZ-337 (the cumulative review F2 notes hygiene defers). - **AZ-508** (E-CC-HELPERS / AZ-264) — `_iso_ts_now` helper consolidation. Depends on AZ-263 only. Stateless stdlib helper; no cross-component or runtime dependencies. NOT a gate on any future product task; can ship in a hygiene-only batch. ## Coverage Verification (Implementation Mode) - **Every product interface in `architecture.md` has implementation task coverage.** - C1 `VioStrategy` → AZ-331 (Protocol) + AZ-332/333/334 (concrete) - C2 `VprStrategy` → AZ-336 (Protocol) + AZ-337/338/339/340 (concrete) - C2.5 `ReRankStrategy` → AZ-342 (Protocol) + AZ-343 (concrete) - C3 `CrossDomainMatcher` → AZ-344 (Protocol) + AZ-345/346/347 (concrete) - C3.5 `ConditionalRefiner` → AZ-348 (Protocol + Passthrough) + AZ-349 (AdHoP) - C4 `PoseEstimator` → AZ-355 (Protocol) + AZ-358/361 (concrete) - C5 `StateEstimator` → AZ-381 (Protocol) + AZ-382..AZ-389 (concrete) + AZ-490 (`set_takeoff_origin` entrypoint + bounded-delta gate) - C6 `TileStore` / `DescriptorIndex` → AZ-303 (Interfaces) + AZ-304/305/306/307/308 - C7 `InferenceRuntime` → AZ-297 (Protocol) + AZ-298/299/300/301/302 - C8 `FcAdapter` / `GcsAdapter` → AZ-390 (Protocols) + AZ-391..AZ-397 - C10 Provisioning → AZ-321/322/323/324/325 - C11 Tile Manager → AZ-316/317/318/319/320 - C12 Operator Tooling → AZ-326/327/328/329/330 + AZ-489 (FlightsApiClient) - C13 FDR Writer → AZ-291..AZ-296 - **Cross-cutting product modules**: - Logging → AZ-266/267/268 - Config + Composition Root → AZ-269/270/271 - FDR Client → AZ-272..AZ-275 - Shared helpers (IMU preintegrator, SE3, LightGlue runtime, WGS, SHA-256 sidecar, engine filename schema, RANSAC, descriptor normaliser) → AZ-276..AZ-283 - Frame source + Clock → AZ-398 - Replay sink → AZ-400 - Replay composition + CLI + auto-sync → AZ-401/402/405 - **No unresolved `AZ-?` placeholders** in any task file (verified by grep on Step 4 close-out). - **E-BBT (AZ-262 / blackbox tests) coverage** vs `traceability-matrix.md`: - **All 35 Covered ACs** map to ≥1 scenario task (AZ-409..AZ-443). - **All 3 PARTIAL ACs** carry the PARTIAL annotation in their pass criteria: AC-8.6 → AZ-423; AC-NEW-5 → AZ-443. - **All 3 NOT COVERED ACs** (AC-7.1, AC-7.2, RESTRICT-CAM-2) are handled by the conftest skip-rule embedded in AZ-406, not by a dedicated task. - **Fixture coverage**: 5 static fixtures (AZ-407) + 3 synthetic injectors (AZ-408) + cold-boot snapshot (AZ-407) cover every scenario's data needs. - **Tier-2-only scenarios**: AZ-428, AZ-430, AZ-440, AZ-443 (and optionally AZ-439's ASan-fuzz mode) all SKIP cleanly on Tier-1 via the conftest tier-guard. - **Reporting**: AZ-445 + AZ-446 produce per-NFR JSONs, `traceability-status.json`, and `regression-baseline.json` for every scenario. ## Cycle Check A static dependency-graph traversal (Kahn topological sort) visits all 142 nodes — no cycles. The 15 forward edges (dep ID > task ID) are all declared, bounded, and documented: - **AZ-267 → AZ-272** (FDR Log Bridge → FdrRecord Schema; shipped in lockstep). - **AZ-298 → AZ-301**, **AZ-299 → AZ-301** (TensorRT / ONNX-RT runtimes → engine gate; runtime ships against the gate's published contract). - **AZ-358 → AZ-381** (C4 OpenCV/GTSAM marginals → C5 SAM2 graph handle; ADR-003 co-development against the AZ-355 Protocol stub). - **AZ-385 → AZ-391, AZ-397**, **AZ-388 → AZ-390, AZ-397** (C5 ↔ C8 co-development; each side ships against the AZ-390 Protocol contract until the consumer task lands). - **AZ-428, AZ-430, AZ-440, AZ-443 → AZ-444** (Tier-2 NFT scenarios → Tier-2 harness wrapper; AZ-439 carries the same forward dep optionally for the ASan-fuzz mode). AZ-444 is therefore scheduled as the first Tier-2 E-BBT deliverable; the dependent scenarios land on top of it. - **AZ-326 → AZ-489, AZ-328 → AZ-489** (C12 CLI + orchestrator depend on the new C12 FlightsApiClient task added 2026-05-11; the client lands first inside the C12 epic and the CLI/orchestrator then plug it in). - **AZ-419 → AZ-489, AZ-419 → AZ-490** (blackbox cold-start scenario forward-depends on both the C12 client + the new C5 entrypoint; the scenario lands after both product tasks). The graph is therefore a strict DAG once these documented forward edges are accounted for, and remains sortable by tracker ID modulo those edges.
