+Final tally: 9/9 pass.
 
 - Tests 1,2,4,5,6: passed during initial UAT.
 - Tests 7 (G-11-7 blocker) and 8 (G-11-8 cosmetic): found as issues, diagnosed, fixed by plans
   11-30/11-31, confirmed on device 2026-07-22.
 
 - Test 3: pass by code inspection (live sourcing infeasible — no zero-favourite gallery exists in
   the wild; parser handles the 'Favorited: Never' rendering at Parser+Detail.swift:266-271).
-Both gaps (G-11-7, G-11-8) status: resolved.

+- Test 9 (G-11-9 cosmetic): found AFTER phase completion — a post-verification regression from the
+  same 6dd51b00 "Overall UI adjustments" HStack->Label sweep that caused G-11-8. Fixed directly
+  (commit 141e3d56, not a gap-closure plan) and verified in-Simulator. Phase left complete.
+Gaps G-11-7, G-11-8, G-11-9 status: resolved.

+  root_cause: "The 6dd51b00 'Overall UI adjustments' HStack->Label sweep (same commit as G-11-8)
+    opted the page-count element into a default-styled `Label`. A default-styled `Label` in a
+    `List` row publishes a `.listRowSeparatorLeading` anchor at its title's leading edge; because
+    this Label sits at the row's TRAILING edge, that anchor collapsed the separator to a sliver.
+    Confirmed by pixel measurement in a List render harness: bug = leading 349.7 / length 11.3;
+    correct = 119.3 / 241.7. The anchor is NOT intrinsic to the `Label` type — it is published
+    only by the Label's default/automatic style-resolution path; routing the Label through ANY
+    explicit `.labelStyle(...)` drops the anchor."

+  fix_applied: "Added `.labelStyle(.titleAndIcon)` to the page-count Label, with a comment marking
+    it load-bearing (NOT a redundant restatement of the default style — a future 'remove redundant
+    modifiers' pass would silently regress the separator). Restores the separator to 119.3 / 241.7,
+    pixel-identical to correct; icon appearance unchanged (keeps .imageScale(.medium)). Considered
+    alternatives: `.alignmentGuide(.listRowSeparatorLeading) { $0[.leading] }` (documented, states
+    intent directly), a custom LabelStyle (works, more code), and a whole-row-as-Label restructure
+    (empirically rejected — mispositions the inset AND overlaps the thumbnail)."
+  verification: "Built + launched in the live iPhone Air (iOS 26.5) Simulator via sim-use; owner
+    confirmed the gallery list separators span full width. Owner also confirmed the Torrents list
+    renders correctly WITHOUT any change — TorrentsView (also a List with trailing stat Labels) was
+    NOT modified; the regression-#4 hypothesis for it was falsified."
+  reusable_lesson: "The `label_text_image_shorthand` lint rule pushes `HStack { Image; Text }` ->
+    `Label`. In a `List` row, a default-styled `Label` at the TRAILING edge hijacks the row
+    separator's leading inset (collapses it) — and, per G-11-8, its icon also inflates vs a bare
+    Image. Any future HStack->Label sweep on List-row content must account for both side effects.
+    Fixes: an explicit `.labelStyle(...)` (drops the separator anchor) and/or an explicit
+    `.imageScale(...)` on the icon (restores glyph size)."
