Adds the per-endpoint child of AZ-795 ("Strict Input Validation Epic")
for the UAV upload multipart endpoint. Three new validators land under
SatelliteProvider.Api/Validators/:
- UavTileBatchMetadataPayloadValidator: items NotNull + NotEmpty +
count <= MaxBatchSize + RuleForEach dispatching to the per-item
validator.
- UavTileMetadataValidator: lat / lon / tileZoom range, tileSizeMeters
> 0, capturedAt within [now - MaxAgeDays, now + future-skew]; uses an
injectable TimeProvider so unit tests can drive a fixed clock.
- UavUploadValidationFilter: IEndpointFilter that reads the multipart
`metadata` form field, deserializes it with the strict global
JsonSerializerOptions (so UnmappedMemberHandling.Disallow +
[JsonRequired] from AZ-795 are honored), runs the FluentValidation
chain, and enforces the cross-field `items.Count == files.Count`
envelope rule. FluentValidation errors are prefixed with `metadata.`
so wire keys look like `errors["metadata.items[0].latitude"]`.
[JsonRequired] is added to every non-optional axis on
UavTileMetadata and UavTileBatchMetadataPayload; FlightId stays
nullable per AZ-503 anonymous-flight semantics.
Coverage: 13 unit tests + 16 integration tests + 1 curl probe script
exercise the happy path and every failure mode. All 9 ACs covered;
no regression in AZ-488 UavUploadTests payloads (traced against the
new rules).
Documentation: uav-tile-upload.md bumped v1.1.0 -> v1.2.0 with the
new validation rules section + 400-shape examples + changelog entry.
api_program.md updated to describe the three new validators + filter
+ the AddTransient<UavUploadValidationFilter>() DI registration.
Reports: batch_04_cycle8_report.md + reviews/batch_04_cycle8_review.md
record the PASS_WITH_WARNINGS verdict (2 Low DRY-in-tests findings:
FixedTimeProvider duplication crossed the cycle-2 "promote to shared"
threshold; PostBatch helper duplicated between two integration
suites). Both deferred to follow-up PBIs.

Replaces the 501 stub at POST /api/satellite/upload with a multipart
batch endpoint that ingests UAV-captured tiles, runs each item through
a 5-rule quality gate, and persists accepted tiles via the AZ-484
multi-source storage path with source='uav'.
Quality gate (in fixed order, first failure wins): JPEG format
(content-type + magic), size band 5 KiB-5 MiB, exact 256x256
dimensions, captured-at age (no future >30 s skew, no older than
7 days), luminance variance on 32x32 downsample. Closed reject-reason
enumeration in v1.0.0 contract.
Authorization: custom PermissionsRequirement / PermissionsAuthorization
Handler that reads the JWT `permissions` claim (tolerates both
repeated-string and JSON-array shapes). Endpoint protected by
RequiresGpsPermission policy; 401 without token, 403 without GPS perm.
Persistence: file-first to ./tiles/uav/{z}/{x}/{y}.jpg, then
ITileRepository.InsertAsync UPSERT (per-source UPSERT contract from
AZ-484). Per-item failures reported in response without aborting the
batch. Kestrel MaxRequestBodySize and FormOptions limits set to
MaxBatchSize x MaxBytes (default 100 x 5 MiB = 500 MiB).
New frozen contract: _docs/02_document/contracts/api/uav-tile-upload.md
v1.0.0. PT-08 NFR added to performance-tests.md as Deferred (harness
work tracked in PT-07 leftover, per AZ-488 § Risk 4).
Tests: 11 quality-gate unit tests, 5 handler unit tests, 3 file-path
unit tests, 12 permission-handler unit tests, 7 integration tests
(AC-1..AC-6, AC-8). All 253 unit tests + smoke integration suite
green.
