Staging merge of three stacks that make no runtime change on Windows or KDE: the KDE Backend/Container/process_command refactors (wip-u-kfde), the shared bar core moves (wip-u-bar) and komorebi-settings with the S1/S2 pins (wip-u-settings). Conflicts, if any, are resolved here. Not yet gated: the KDE VM suites and the Windows bar check are owed.
Measured on wip-main 633e7453 by grep and reading: 126 (Windows), 53 (KDE)
and 74 (macOS) static declarations, of which 61/35/36 are configuration and
51/29/28 are written by apply_globals. The document has the per-static
table (type, writers, readers, shared or platform, matching name), the lock
order of the rule lists, the proposed Settings (shared part plus a platform
type parameter, snapshot reads, serialised updates, scoped override), the
statics whose semantics would change (reload merges rather than replaces;
partial updates visible mid-reload; save-and-restore writes; the empty
WORKSPACE_MATCHING_RULES window), the migration order with pure refactor
versus BEHAVIOUR marks and the gate each needs, and section 7 with the
findings from encoding the semantics in the crate (aspect ratio starts at
Widescreen but a load without the key writes Standard).
Verified: nothing run (documentation); counts from grep, line numbers read
at 633e7453.
docs/dev/core-model.md: per-file measured differences between the
Windows, KDE and macOS container, monitor, workspace, window and
window_manager (stripped code lines, changed lines, identical lines),
the platform-specific fields and methods of each layer, a proposed
split into a komorebi-core crate generic over a Platform (Backend plus a
Copy-or-Clone Window and a state type) with the exact order of layers
(container, monitor, workspace, window_manager, router), what the KDE
stack of wip-u-kfde already did, what Windows must do before the crate
can be created, and the list of KDE process_command arms over 20 lines
with the method each became. Measurements are from diff of the files at
this tip; nothing was run on Windows or macOS.
Verified: not applicable (documentation); the numbers were produced by
diff and wc on the files at wip-u-kfde.
docs/dev/bar-unification.md is brought up to date: what the core holds now
(4,592 lines, the hooks), what is still per platform with fresh
measurements (komorebi.rs 136 differing lines, network.rs 82, bar.rs 444,
main.rs 92, os.rs 71) and why each stays, the known macOS/Windows
differences kept on purpose (including the accept-and-skip of Windows-only
keys, D-coord-1), the proposed layout of the merged package for the
coordinator (module layout with cfg(target_os), dependencies by target,
schema flag, lock-file folding, nix), the ordered plan and the hand check
list. No code changed. The macOS hand-check section for
docs/dev/macos-handcheck.md (owned by kfm, not in this tree) is in the
scratchpad as bar-handcheck-section.md for the coordinator to append.
Verified: figures from diff on this tree. Gates at this tip: native bar-core
tests 3+6, schema harness macOS and Windows byte-identical, Windows clippy
and macOS fake-CC check clean.
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.
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).
