process_command (close and minimize of the foreground window, four raise
calls) and monitor_reconciliator (four minimize calls) now call
backend().close/minimize/raise. WindowsBackend runs Window::close,
minimize and raise unchanged (minimize still leaves komorebi-bar alone).
docs/dev/backend-switch.md now holds the full table of what is switched
and what is left, including why the queries (window_rect,
foreground_window, cursor_pos, monitors) were NOT switched: each would drop
an error that callers use or report, or fabricate a default.
BEHAVIOUR: a dead window is skipped by an IsWindow check first; minimize
results are ignored as before. e2e gate needed: commands, monitor
reconciliation (monitor_reconciliator), lifecycle. Verified: Windows clippy
-D warnings via tools/fast-check PASS; e2e not run.
Switch the 40 Window::focus(mouse_follows)? call sites in process_event,
process_command, workspace, window_manager, focus_manager and the
stackbar click to backend().focus(WindowId::from_hwnd(..), mouse_follows).
WindowsBackend::focus runs Window::focus, so the deferral while a window
slides in, the already-foreground shortcut and the cursor centring are
unchanged. animation/transition.rs:534 stays on Window::focus (it is the
code Window::focus defers to). docs/dev/backend-switch.md records what is
switched.
BEHAVIOUR: a dead window now fails early with Error::WindowGone (before:
the Win32 error from raise_and_focus_window) and a failed focus of a window
that died meanwhile reports WindowGone; every caller uses ? or ignores the
result. e2e gate needed: commands, focus, focus_follows_mouse, stacking,
workspaces, lifecycle. Verified: Windows clippy -D warnings via
tools/fast-check PASS; e2e not run.
docs/dev/bar-unification.md: why config.rs, bar.rs and komorebi.rs are not
moved yet, file by file with the measured difference (differing lines and
hunks), the structural blocker (two Cargo workspaces/lockfiles/flakes, two
komorebi-client crates), the schema views that settle schema.bar.json, the
ordered plan, KDE (no bar exists), the macOS commands that spawn cmd.exe or
explorer.exe and are preserved in os.rs, and what must be checked by hand on
Windows and on a Mac.
Verified: figures from diff on this tree; no code changed. Gates at this
tip: schema harness macOS and Windows byte-identical, native bar-core tests
3+5 passed, Windows clippy and macOS fake-CC check clean.
Adds the three BEHAVIOUR-relevant registry revisions (registration and
forgetting, native-tab sync) with what to look for on a Mac, the mechanical
ones to section B, and a status entry in the bug list saying what of step
11(ii) is done and what is deliberately not (animator lanes, borders,
reaper/live-resize timeouts, the model holding bare ids).
Verified: documentation only.
Lists what must be checked on a Mac once the unified binaries exist: every
macOS revision that changes runtime behaviour (the rule-list lock order,
the shared command listener, pause filter, subscriber push, EventChannel,
SocketMessage, animation prefix, StaticConfig, komorebic launcher, bar-core
hooks and library bumps), the mechanical Step 6/11(i) revisions of this
stack, the walk-through the plan names (focus, move, stack, workspaces,
scrolling, pan, borders, animations, display change, sleep and wake), and
the bugs noticed: the main-queue/WM-lock deadlock of seam.md 3.3, cmd.exe
and explorer.exe in the macOS bar, the update widget's wrong repo, the raw
AX sites that remain outside Window.
Nothing in it was run: macOS cannot be built or tested on this host.
Verified: documentation only.
Appends section 9 to docs/dev/seam.md: for each method of the shared Backend, what WindowsBackend and MacosBackend do and where that differs from what the daemon calls today (windows() and macOS's registry cannot be written faithfully; set_rect on Windows drops the top flag and keeps animation and guards; hide/restore results are ignored on Windows; macOS hide needs a corner and a display; raise on macOS also focuses; macOS monitors() has to be a main-thread-refreshed cache; set_opacity on Windows is the plain write). Concludes that the trait did not have to change and records three proposals (rect as Option, hide's hidden inputs, windows() as start-up operation).
Verified: docs only, not built. Every claim is by reading the code while writing the adapters; what could not be settled by reading is marked 'not verified' in the text.
Adds section 7 (the seven consequences of plan step 7, each with its supporting citations and a status: CONFIRMED, CORRECTED or TARGET; plus three findings the plan did not list: a batch/transaction scope, the workspace methods that exist only on KDE, and error-type differences) and section 8 (everything not confirmed, with how to confirm it on a Mac, a Windows guest or by reading). Verified against the citations of sections 2 to 6 on wip-main aa52fdc4d9e5. Not verified: see section 8.
Adds section 6: event sources per platform and how they reach the window manager (references the step 5 prep entries rather than redoing them) and the evidence for the 'set_rect returns once requested, the frame is observed later' contract: KDE queued commands with an optimistic table write, macOS arrival.rs, settle.rs and animator verification, Windows live_resize settling. Verified against wip-main aa52fdc4d9e5: K/kwin/mod.rs, K/kwin/state.rs, K/window_manager_event_listener.rs, K/backend/mod.rs, M/arrival.rs, M/settle.rs, M/animation/animator.rs, M/window.rs, M/window_manager_event_listener.rs, W/winevent_listener.rs, W/windows_callbacks.rs, W/live_resize.rs. Not verified: any runtime ordering of events.
Adds sections 4 (identity: id types per platform, what acting on a macOS window from a bare id would need, where each tree keeps per-window platform data, HWND width including an observation of 440 distinct HWNDs from the Windows guest logs) and 5 (coordinates: Rect convention, origin and y direction, DPI and scale handling, shadow and frame compensation, and where each conversion lives). Closes two plan items: Windows HWND width and macOS Retina points versus pixels. Verified against wip-main aa52fdc4d9e5: komorebi-layouts/src/rect.rs, W/window.rs, W/windows_api.rs, W/lib.rs, K/kwin/state.rs, K/kwin/bridge.js, M/window.rs, M/application.rs, M/macos_api.rs, M/core_graphics/mod.rs, M/core/rect_ext.rs, M/border_manager/border.rs, M/animation/ghost.rs, M/animation/capture.rs, and ~/e2e-w0 logs read-only for the HWND range. Not verified: HWND width as a Microsoft guarantee, AX values on scaled-resolution or mixed-DPI displays, negative monitor origins on Windows.
Adds section 3.3: the macOS main thread (AppKit and CFRunLoop loop, what runs there), every other thread with its locks, every DispatchQueue::main exec_sync/exec_async/blocking-channel site with file:line and whether the main-side closure takes the window-manager lock, and a precise statement of the possible event-thread/main-thread deadlock, marked by reading, not reproduced. Verified against wip-main aa52fdc4d9e5: M/main.rs, M/macos_api.rs, M/monitor_reconciliator.rs, M/border_manager/{mod,border,ns_window}.rs, M/animation/{animator,ghost}.rs, M/process_event.rs, M/process_command.rs, M/reaper.rs, M/settle.rs, M/workspace_reconciliator.rs, M/window.rs, M/application.rs, dispatch2-0.3.1/src/queue.rs. Not verified: that NSWorkspace and CG display callbacks arrive on main (Apple behaviour), that CFRunLoopAddSource from a non-main thread is safe, that AXUIElement is thread-safe (the code asserts Send+Sync), and the deadlock itself (needs a Mac).
Adds sections 3.1 (KDE) and 3.2 (Windows): every thread that exists, what it locks, and which threads call the platform API. Closes two items the plan listed as unverified: which threads call backend() in KDE (traced: main at start-up and stop, the event thread, command threads, the monitor reconciliator and its settle thread, and tests through with_backend; never the KWin bridge or the hotkey threads) and which threads call WindowsApi, with the thread-affine subset. Verified against wip-main aa52fdc4d9e5: K/main.rs, K/kwin/mod.rs, K/kwin/hotkeys.rs, K/process_event.rs, K/process_command.rs, K/monitor_reconciliator.rs, K/backend/mod.rs, W/main.rs, W/winevent_listener.rs, W/windows_callbacks.rs, W/border_manager, W/stackbar_manager, W/animation, W/live_resize.rs, W/reaper.rs. Not verified: Microsoft's documented behaviour of WINEVENT_OUTOFCONTEXT and cross-thread SetWindowPos, and every Windows call chain (the table lists thread entry points and the API each reaches, not every path).
Adds section 2: the operation table (one row per operation present on at least two platforms: KDE Backend method | Windows | macOS | semantic differences), the platform-subsystem table, and the re-measured counts with the exact method. Verified against wip-main aa52fdc4d9e5: K/backend/mod.rs, K/kwin/mod.rs, W/windows_api.rs, W/window.rs, M/macos_api.rs, M/window.rs, M/core_graphics/mod.rs, M/lib.rs. Not verified: how each AX call behaves against real applications (needs a Mac), and the counts are of source text, not of executed calls.
Creates docs/dev/seam.md with sections 1 (purpose and how to read) and the corrections list. Verified against wip-main aa52fdc4d9e5 by reading K/backend/mod.rs, K/kwin/mod.rs, K/kwin/state.rs, M/macos_api.rs, M/window.rs, M/arrival.rs, M/process_event.rs, M/process_command.rs, W/windows_api.rs. Counts quoted here are measured in the next revision. Not verified: any runtime behaviour (the document is reading-only).
