Version every /api route to /api/v1 (251 controller routes + ~24 Location
headers + the scanner callback URL + the Startup request-log literal),
uniform across the machine API, auth, scanner and scripted-build surfaces.
Add ApiVersionRewriteMiddleware: a legacy unversioned /api/* request is
rewritten (NOT redirected) to /api/v1/* in-pipeline — method, body, auth
headers and query survive — carrying RFC 8594 Deprecation/Sunset headers,
so curl / the future MCP server / bookmarks keep working. An already-
versioned path passes through; a future /api/v2 is never forced to v1.
Standardize the route convention (leading-slash absolute route per method,
no class-[Route] — except the two Scanner/Scripted controllers whose ~all
actions share a parametrized {id} prefix), enforced by ApiRouteVersioningTests
(^/api/v\d+/ over the whole Controllers.Api surface; browser-nav
/auth/oidc/login is out of scope).
Regenerate v1.json (160 paths, all /api/v1)/endpoint-index/v1.d.ts; sweep 945
SPA request literals + the test mocks (regex + positional URL parsers). /api/v1
is additive-only after freeze; the legacy-rewrite shim sunsets in ~2 releases
(owner decision) with removal tracked as a Phase-3 follow-up.

S4 stored-XSS + S9 upload-size DoS from the #197 cold API review.
The artwork path trusted client-supplied content types at both ends: upload
validated only the declared multipart Content-Type (never decoded the bytes),
and serving reflected a client `?contentType=` straight into the response
Content-Type on unauthenticated GET sinks (/iptv/logos, /artwork/watermarks).
Chain: upload <script> bytes as image/png -> GET ...?contentType=text/html
serves them as HTML in-origin. nosniff (#279) does not help because the server
explicitly declares text/html.
- Upload: derive the content type from the bytes via SkiaSharp SKCodec
(header-only, no decode -> no decompression-bomb path); reject non-images 422.
New ErsatzTV.Core/Images/ImageContentTypes as the single allow-list source.
Dropped the untrusted declared Content-Type from the UploadArtwork command.
- Serve: removed the ?contentType= reflection structurally -- dropped ContentType
from GetCachedImagePath and the [FromQuery] binding on GetImage/GetWatermark;
the handler always sniffs the file, defaulting application/octet-stream.
ArtworkContentTypeModel.UrlWithContentType is now the bare path; SPA previews
no longer append the query.
- Defense-in-depth: channel-logo / watermark {path, contentType} DTOs run through
ArtworkContentTypeModel.Sanitized(), blanking non-allow-listed types on write.
- S9: Kestrel MaxRequestBodySize from ETV_MAXIMUM_UPLOAD_MB rejects oversized
bodies during read (controller file.Length check kept as friendly-error backstop).
Both serve sinks are IgnoreApi, so no OpenAPI change. Tests: byte-sniff accept/
reject, Sanitized() allow-list, Location no longer carries ?contentType=.

POST /api/artwork/uploads (multipart/form-data) accepting logo and
watermark images. Validates content type (png/jpeg/gif/webp) and size
(SystemEnvironment.MaximumUploadMb, default 10MB) mirroring the Blazor
upload path; stores via IImageCache.SaveArtworkToCache; returns
{ path, contentType } consumable by channel create/update.
Includes handler + controller tests, OpenAPI 422 contract-test entry,
and regenerated v1.json.
