Backend: 401 documented on all mutating settings/resolution routes; resolution delete distinguishes 404 (unknown) from 422 (not custom); XMLTV enum bridging via exhaustive switch instead of int casts; field-level Arg.Is assertions incl. non-null watermark/filler flow. Frontend: resolution add/delete failures surfaced inline (were silent); partial saves merge succeeded groups via allSettled; empty numeric fields invalid + tunerCount min 1; HLS Direct select shows out-of-list wire values; media-source rows show derived last-scan. ErsatzTV.Tests 495; web suite 145. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
