Open two ~2-point hygiene PBIs surfaced by _docs/03_implementation/cumulative_review_batches_31-33_cycle1_report.md: - AZ-507 (parent AZ-246 / E-CC-CONF) — align module-layout.md cross-component import rules with the AZ-270 lint test. Resolves the doc-vs-lint contradiction surfaced on AZ-321 by tightening the doc (option (a) from the review) + hoisting EngineBuildError / CalibrationCacheError to _types/inference_errors.py. - AZ-508 (parent AZ-264 / E-CC-HELPERS) — consolidate 5 identical _iso_ts_now() one-liners across c6_tile_cache + c7_inference into a single Layer-1 helper at helpers/iso_timestamps.py. Dependencies table headers bumped: 142 -> 144 tasks, 478 -> 482 points (product 345 -> 349). State file's pause-point detail cleared; next sub_step is the implement skill's Step 3 (compute next batch) for batch 34. Co-authored-by: Cursor <cursoragent@cursor.com>

# 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**.

## Notes
|
||
|
||
- **Forward dependency on AZ-272** in AZ-267: the FDR Log Bridge task
|
||
declares a forward dependency on the FdrRecord Schema (AZ-272). 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.
