+- 2026-09-07 S7.3 implemented in worktree `agent-a46673911c3cc2a31`
+  (branch `worktree-agent-a46673911c3cc2a31`, on top of `89a49836c`).
+  One commit `57ced0aff`: the Monsters tab body is now VTank's own
+  23-column HudList grid (14 check + 7 text + 2 icon columns, 15 header
+  `<label>`s carrying the decompile's own tooltip text) transcribed
+  from `docs/research/vtank-kb/08-ui-views.md` §1 and
+  `PluginCore.cs:7885-8105`'s per-cell handler, replacing the old
+  select-then-edit adaptation entirely. Deviation: Weapon/Offhand
+  columns cycle the registered weapon roster (Items tab) rather than
+  VTank's own opaque weapon-TYPE id list, since MossTank models
+  equipment as concrete owned items, not types — see the commit body
+  for the full reasoning. Every new/changed pin shown to fail against a
+  targeted mutation first. Full suite green (651/651 MossTank — net +6
+  over S7.1/S7.2's 645, 109/109 App markup-filtered). S7.4-S7.6 (Items/
+  Consumables/Buffs/Route/Meta) and S7.7 (gate script) remain out of
+  this sub-slice's scope. Screenshots NOT captured (same ACE-down
+  reason as S7.1/S7.2). Owner's visual gate against a running VTank is
+  still owed for both S7.1/S7.2 and S7.3.
