chore: preserve reviewed X4-exact-nano source proposal and provenance

Original product proposals are unchanged. The canonical index links all branch checkpoints; validation and owner handoffs remain pending.

-# The kernel rig and the complexity ladder as a regression gate. A plan job maps a pull request's
-# changed files to the rig areas they can affect (scripts/ci/kernel_rig_plan.py): an area runs
-# when a file its tests/kernel-cases/<area>/PATHS lists changes, or one of its cases; every area
-# runs when the shared core in tests/kernel-cases/PATHS-ALL changes; the ladder runs whenever any
-# area does. One job then builds solidcraft-cli once (release, SMLib prebuilt), checks that every
-# registry command has a case or an exemption (tests/kernel-cases/EXEMPT), and hands the CLI to a
-# matrix of shards as an artifact, one per selected area plus the ladder, in parallel, so the
-# wall time is the build plus the slowest shard. See tests/kernel-cases/README.md.
-#
-# - An area fails on a regression (a case that fails and its tests/kernel-cases/<area>/KNOWN_FAILING
-#   does not list) or on a listed case that passes (it is fixed: remove its line in the same pull
-#   request, so the list only shrinks).
-# - The ladder fails on any case whose status or counts differ from
-#   tests/kernel-cases/ladder/golden.json; a right change is re-recorded (`--record "why"`).
-#
-# The trigger paths are whole folders that hold every area's PATHS (a self-test,
-# scripts/ci/test_kernel_rig_plan.py, checks they do), so a pull request that touches none of
-# them (the UI, docs, packaging) starts no runner at all, and a new area needs no edit here: the
-# plan finds the areas from the folders. Pushes to main and develop on the same paths, merge groups
-# (once the queue is on), the release gate (release-gate.yml, workflow_call) and a run by hand run
-# every area; those pushes also commit the compiler cache (a Blacksmith sticky disk) that every
-# other run mounts read-only.

+//! Bringing the window forward when a close stops at "save changes?".
+//!
+//! A close from the taskbar or a window switcher reaches the window while another app has the
+//! focus. The prompt it opens is only seen once the window comes forward, so the window asks for
+//! the focus then. A window the user is already in is left alone.
+//!
+//! winit's Focus asks as an application, which a window manager with focus-stealing prevention
+//! (KWin's default) refuses for a window used before the switch away: it only marks the taskbar
+//! entry. On X11 the request is sent again with the source EWMH gives "direct user actions"
+//! (`_NET_ACTIVE_WINDOW`, source 2), which is what this is: the prompt is the rest of the user's
+//! close. Native Wayland has no way for a window to raise itself, so there the attention request
+//! (xdg-activation) lets the compositor raise it or mark its taskbar entry.
+//!
+//! When: not at once. KWin raises the window, then the taskbar's closing context menu hands the
+//! focus back to the app that had it, a few milliseconds later, and the window would flicker
+//! forward and back. So the window asks once the menu is gone, `FIRST_AFTER` the close. It asks
+//! again only if the focus is taken back right after it came (a slow menu) or never came; a later
+//! switch is the user's own, and the window stays where the user put it.

+
+## Output and result
+
