-# overview-header.sh — RETIRED.
+# overview-header.sh - retired compatibility shim.
 #
-# This script used to split the overview window to host an in-binary
-# `fleet-tab-strip` Rust header pane. That crate was retired in PR #107;
-# the iOS-style nav strip configured by style-tabs.sh
-# (`status-position top` + window-status-format pills) is now the single
-# canonical nav surface. The status bar is visible on every window — not
-# just overview — so the dedicated header pane is no longer needed.
+# Plan codex-fleet-glass-menu-drop-tabstrip-2026-05-15 removed the
+# standalone `fleet-tab-strip` Rust header pane. The iOS-style nav strip
+# configured by style-tabs.sh (`status-position top` +
+# window-status-format pills) is now the canonical nav surface. The status
+# bar is visible on every window, so the dedicated header pane is no longer
+# needed.
 #
 # Kept as a no-op for backwards-compat: anything still wired to call this
 # (e.g. older operator runbooks, sibling sessions like codex-fleet-2.sh)
 # just gets a clean log line and continues, instead of a hard error from
 # the missing binary lookup.
 #
+# The old implementation first checked for an existing header pane before
+# splitting the overview window:
+#
+#   tmux list-panes -t "$target" -F '#{@panel}' \
+#     | grep -qFx '[codex-fleet-tab-strip]'
+#
+# This shim deliberately treats every invocation as the skip path: no binary
+# lookup, no split-window/select-pane, and no pane @panel marker writes.
+#
 # Usage:
 #   bash scripts/codex-fleet/overview-header.sh        # no-op, exits 0
