+### TV feedback corrections (spec revision 5)
+
+The [revision-5 amendment](../data/tv-spec/spec.md) and
+[native frame prototype delta](../data/tv-v2/feedback-2026-11-06/index.html)
+retain the approved frames except for the requested feedback changes:
+
+- The picker gear is centred under everyone and uses the picker-person ring.
+- Shelf tracks share second-last-slot lookahead, count clamping and settled
+  offsets. Home records completed frame positioning rather than an animation
+  that may still be cancelled; first mount restores the intended shelf item.
+  Discover uses all six approved poster slots. Person keeps the final column
+  at full poster width.
+- Episode images choose episode Primary, then Thumb, then the already-read
+  series Backdrop. Episode cards are 400×280 px; cast retains its 68 px clearance.
+  Episode context uses the episode overview, with two summary lines on the
+  focused card. Held-series headers measure their copy/actions and leave 40 px
+  before seasons instead of reserving a fixed empty 900 px header.
+- Every Discover heading uses a 104 px band, including a 60 px title-to-card
+  gap. Home heading geometry is unchanged.
+- Hero/backdrop decoding is bounded to 1920×1080; upright hero sheets request
+  420×630. The shared request builder removes conflicting Jellyfin size caps,
+  preserves tags and quality 96, and selects a suitable TMDB tier. The 64 MiB
+  memory cache, 128 MiB disk cache and four image-read limit remain unchanged.

+`HomeViewportTest` covers short/long poster, tile and wide rows, both row
+directions, first focus and native Back from the actual title surface. Native
+proof records real Bear season-three metadata through the title read facade;
+the proof-only harness is not part of the shipped tests or APK.
