Per-Task Classification

AZ-504 — Perf script: fix grep | wc -l pipefail crash

Verdict: PASS (with explicit Step 15 deliverables)

Evidence:

• scripts/run-performance-tests.sh:416-417 — both accepted and rejected count expressions now wrap grep -o in { grep -o ... || true; } so set -o pipefail does not kill the pipeline on zero matches.
• AC-1, AC-2 verified by standalone harness (4 cases under set -e -o pipefail).
• AC-3, AC-4 are explicitly deferred to autodev Step 15 (Performance Test) by task spec design — AC-4's GIVEN clause depends on AC-3 + "the full perf run is green". The deferral is not a gap; it is the natural Step 15 deliverable. Confirmed in _docs/03_implementation/batch_01_cycle5_report.md and in the perf-cycle3 leftover entry.

Search for unresolved markers (placeholder, stub, TODO, NotImplemented, fake, mock, scaffold, native bridge) in the patched file: none in the patched region.

No named runtime dependencies in the task promise.

AZ-503-foundation — Tile identity → UUIDv5 + integer UPSERT (foundation)

Verdict: PASS

Evidence (source code, not tests or reports):

• SatelliteProvider.Common/Utils/Uuidv5.cs — pure-C# RFC 9562 §5.5 (SHA-1) UUIDv5 implementation, 80 LoC. No third-party dependency. TileNamespace = 5b8d0c2e-7f1a-4d3b-9c5e-1f3a8e7d2b6c pinned cross-repo (must match gps-denied-onboard/components/c6_tile_cache/_uuid.py:TILE_NAMESPACE).
• SatelliteProvider.Common/DTO/UavTileMetadata.cs — FlightId (Guid?) plumbed through.
• SatelliteProvider.DataAccess/Migrations/014_AddTileIdentityColumns.sql — applied against the live DB; verified columns flight_id uuid NULL, location_hash uuid NOT NULL, content_sha256 bytea NULL, legacy_id uuid NULL; verified idx_tiles_unique_identity with COALESCE(flight_id, '00000000-...'::uuid); verified idx_tiles_location_hash; verified AZ-484 index idx_tiles_unique_location_source dropped.
• SatelliteProvider.DataAccess/Models/TileEntity.cs — 4 new properties.
• SatelliteProvider.DataAccess/Repositories/TileRepository.cs — InsertAsync UPSERT uses the new integer-only key + COALESCE(flight_id, ...). id is intentionally NOT updated on conflict (preserves AC-2 idempotence).
• SatelliteProvider.Services.TileDownloader/TileService.cs:146-196 — BuildTileEntity computes deterministic Id = Uuidv5.Create(TileNamespace, "{z}/{x}/{y}/google_maps/{empty-guid}") and LocationHash = Uuidv5.Create(TileNamespace, "{z}/{x}/{y}"). No Guid.NewGuid() call remains. ContentSha256 computed from the on-disk JPEG body via SHA256.HashData(stream).
• SatelliteProvider.Services.TileDownloader/UavTileUploadHandler.cs:144-217 — PersistAsync reads metadata.FlightId, computes deterministic Id + LocationHash + ContentSha256, writes file to ./tiles/uav/{flight_id or 'none'}/{z}/{x}/{y}.jpg. BuildUavTileFilePath takes a Guid? flightId parameter.

→ no matches. (stub matches appear only in test-only fixtures from prior cycles; out of this task's scope.)

Named technologies / integrations promised by the task:

• PostgreSQL pgcrypto extension — migration enables it via CREATE EXTENSION IF NOT EXISTS pgcrypto and uses it for the SHA-1-based UUIDv5 backfill. ✓
• Cross-repo gps-denied-onboard UUIDv5 contract — pinned namespace constant matches by spec (Python parity verified by 10 reference vectors in Uuidv5Tests). The onboard repo's matching change is a separate cross-workspace task (AZ-304 in gps-denied-onboard). This is out of scope for the satellite-provider workspace by the AZ-503-foundation spec — both sides are coordinated but not co-implemented.

Deferred ACs (5 of 12) are explicitly out of scope per the user-approved split (Option C, /autodev step 10 batch 2):

• AC-5 (inventory endpoint), AC-6 (Leaflet path rewrite), AC-9 (perf SLO), AC-10 (index-only EXPLAIN), AC-12 (HTTP/2) → all moved to AZ-505 with a Blocks link.

End-to-end production pipeline check: the TileTests.RunGetTileByLatLonTest integration test produced tile id e228d1aa-25d4-556e-a72d-e0484756e165 — a valid UUIDv5. This confirms the production path (HTTP request → Google Maps download → TileService.BuildTileEntity → TileRepository.InsertAsync → deterministic id) is connected end-to-end, not just in unit tests.

Gate Verdict: PASS

Every product task is PASS. No FAIL, no BLOCKED.

• No remediation tasks required.
• Proceed to /implement Step 16 (Final Test Run). Per the existing-code flow, the next autodev step (Step 11 — Run Tests) owns the full-suite gate, so /implement Step 16 hands off to autodev Step 11 rather than re-running the suite.

Handoff to autodev Step 11 (Run Tests)

The full integration suite was already run twice during /implement Step 6. Results:

• Run 1 (during batch 2): failed at UavUploadTests.MultiSourceCoexistence_AZ484_Cycle2 due to my AZ-503 migration making location_hash NOT NULL while that seed test inserted a raw row without it. Fix shipped (UavUploadTests.cs seed computes location_hash via Uuidv5.Create). After fix, the test passed.
• Run 2 (post-fix): passed JWT (8 ACs), all UAV upload tests (10 ACs including AZ-503 AC-3 + AC-4), and TileTests.RunGetTileByLatLonTest. Failed mid-way through RegionTests.RunRegionProcessingTest_200m_Zoom18 due to intermittent DNS resolution failure on mt1.google.com from the Docker test container. This is host-network flakiness, not an AZ-503 regression — same failure mode appeared in Run 1 against tile.googleapis.com before the AZ-503 fix was applied.

MigrationTests (which sit at the end of the suite, after the flaky Region tests) did not execute via the runner during Run 2 but were verified directly against the running DB: column shape, index shape, deterministic backfill formula match (SQL UUIDv5 of "18/12345/23456" = 38b26f49-a966-5121-aaf4-9cc476f57869 — byte-identical to the C# unit test vector), and live row equality on three sampled rows.

Recommendation for autodev Step 11: the user can re-run the full suite or accept the partial evidence above + the verified DB schema. Either way, no AZ-503-related test failures remain.

Cycle 5 is complete from the implementation perspective; AZ-505 carries the deferred scope into a future cycle (already linked in _docs/02_tasks/_dependencies_table.md).
