Subject: split-view phase 4: split-aware status, min-width gate, verified nav
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Polish for the split view:
* _split_status(): status line now reads "name @ ea [split · pseudocode line N
  ↔ K insn]" / "[split · listing]" from the focused pane, instead of the
  single-view [pseudocode]/[listing] labels clobbering it. Wired into both
  cursor-moved handlers and _apply_decomp.
* min-width gate: action_toggle_split refuses to enter split below
  _SPLIT_MIN_WIDTH (100 cols) so two usable code panes always have room.
* navigation keeps both panes on the same function: verified (not fixed —
  goto/follow in split already routes _open_entry -> _show_active split branch,
  reloading the listing + decomp + region map for the new function).

Review turned two roadmap items into non-issues: split is a persistent mode
orthogonal to nav entries (back/forward just navigate within split), and search
is already per-focused-pane.

Pilot split_view gains: split-aware status, goto-in-split navigates, and both
panes reload on navigation (16/16). Full suite 157/2-flake. Split view is
feature-complete (phases 1-4).

+- Split-aware status: `_split_status()` shows `name @ ea [split · pseudocode line
+  N ↔ K insn]` / `[split · listing]` instead of the single-view labels.
+- Min-width gate: `action_toggle_split` refuses to enter split below
+  `_SPLIT_MIN_WIDTH` (100 cols) — two usable panes need the room.
+- Navigation keeps both panes on the same function: verified — a goto/follow in
+  split routes through `_open_entry` (listing) → `_show_active` split branch
+  (decomp + `_load_split_map`), so both panes reload for the new function and
+  split stays on.
+- Non-issues after review: split is a persistent *mode* orthogonal to nav
+  entries, so back/forward simply navigate within split (no per-entry state
+  needed); search is already per-focused-pane.
