2025-12-01Let a new window pick its own size instead of forcing a guessed placeholdersrdusr3-0/+59
Root-caused "windows spawn small and square, not remembering placement or size": new_managed_window hardcoded a fresh toplevel's geometry to 800x632 before the client had said anything about its own preferred size, and sync_geometry forced that guess onto the client's very first xdg_toplevel::configure unconditionally. Per xdg-shell, size: None on that first configure is how every mainstream compositor lets a client pick its own natural size instead; this one never did, so every app converged on the same placeholder rectangle regardless of what it would have chosen. Window::size_is_provisional marks a size that really was just the guess (not a remembered geometry, a rule's explicit geometry action, or a maximize/phone-mode fill, none of which are guesses). sync_geometry sends size: None for such a window's first configure; a new adopt_provisional_size, called from the commit handler, adopts the client's own real first size into Window::geometry the moment it commits one, clamping only position so a bigger-than-guessed window can't hang off its monitor's edge. Live-verified in a nested compositor: a zenity dialog now renders at its own compact natural size instead of being stretched to the old guess.
2025-11-07Make tiling's master/stack ratio live, add settings readback everywheresrdusr4-7/+303
Investigated the "tiling needs a lot of work" report directly. The MasterStackLayout algorithm itself was already correct; the real gap was that dragging or resizing a tiled window did nothing durable (raw geometry that the next arrange_workspace silently discarded), and master_ratio/master_count had no live path at all (config-file only). A resize-drag on the shared master/stack boundary now live-adjusts TilingConfig::master_ratio and re-arranges the group immediately; srd set master_ratio/master_count do the same for a keybind or script. Found and fixed a real bug while building this: start_resize's own focus_window call re-stacks its target in self.order before the ratio-drag decision used to be made, silently misclassifying real master-column grabs. Fixed by deciding ratio-drag status (and freezing the membership snapshot it depends on) before that raise happens, applying MasterStackLayout directly against the frozen snapshot rather than re-deriving membership from the by-then-reordered live order. Live- verified in a nested compositor, not just unit-tested. Also closes the readback gaps flagged directly by the AGS peer session: border_width/border_color/corner_radius/decoration_mode/gap_inner/ gap_outer/master_ratio/master_count were all live-settable via srd set with no way to read the current value back, and pin_input had no readback at all. SettingsResponse now reports all of them; a new pinned_inputs query (srd pinned inputs) lists every currently pinned pid/window.
2025-11-04Fix window memory never saving on close, and split-screen icon/primary bugssrdusr2-1/+53
Screenshotted the just-split display on request rather than guessing -- it showed why windows never seem to remember placement/size, plus two real split-screen bugs. Window memory (WindowManager::remembered_geometry) was correctly wired on the read side, but the only writes came from end_drag/end_resize in dragresize.rs - a real drag or resize. A window the user opens, looks at, and closes without ever touching its edges had nothing recorded, so reopening it always fell back to a fresh cascade placement, for what is probably most ordinary window lifecycles. remove_window now also snapshots geometry (same app_id-non-empty gate the drag/resize sites use), persisted at both of its wayland-side call sites the same way the drag/resize-release site already does. desktop_icon_origins mirrored the full icon set onto every Monitor entry when general.desktop_icons_all_monitors is on - which, after a srd.monitor.split, is one entry per split part of the same physical screen, not one per real monitor. Extracted into a separately-tested icon_origins_for that collapses split parts of the same connector back to one origin, keeping a genuinely separate monitor's own origin intact. Found while fixing that: every split part also reported primary: true (computed from the connector's name, which doesn't vary per part) -- fixed by gating on part == 0 too.
2025-10-29Fix set_monitor_split never actually reaching srd monitorssrdusr2-0/+35
Live-tested right after shipping it and caught immediately: srd dispatch set output split returned ok, but srd monitors kept reporting the whole, unsplit output. WindowManager::monitors is a passive cache, only refreshed when a backend re-queries and calls set_monitors again - the IPC handler mutated the split map directly but never triggered that requery, unlike set_output_position's own drain site, which already pushes a "just go recompute" event after applying. Makes it a proper queued cross-boundary request instead, the same shape as every other backend-owned effect on this socket: WindowManager:: request_monitor_split/drain_monitor_split_requests, dispatch queues instead of mutating, the udev backend's poll drains it, applies via set_monitor_split, and pushes the same recompute event. srd.monitor. split's Lua config-time path is untouched - it runs before the very first startup query, so it never had this problem.
2025-10-26Live-expose monitor split, clean up leftover debug diagnosticssrdusr1-21/+0
srd.monitor.split only ever ran at Lua config load despite being a plain WindowManager mutation that every backend's monitors() already reads fresh on each call. Adds srd dispatch set output split <name|id> <parts> [rows|columns] (IPC set_monitor_split), same id-resolves-to-name pattern set_output_enabled already uses. Also removes eight log::warn!("XXX-DIAG ...") lines left behind from live debugging in the multi-session shift that landed in 3c41fc4 - the same "temporary, never removed" pattern already fixed twice earlier this session. Several fired on genuinely constant interaction (every title change, every workspace switch, every layer-shell surface hide), not just a one-off leftover. Left xdg_shell.rs's own POPUP-GEOM-DIAG/ POPUP-GRAB-DIAG alone - that one is a still-open, self-documented investigation, not litter. Also documents (docs/TODO.md, not a code change) a live incident where creating a second fake monitor visibly corrupted the real monitor's position and kept drifting with no further input - not root-caused srdwm-side, flagged to the AGS peer session since a fake monitor's real wl_output global is indistinguishable from a real hotplug to GDK/GTK. And documents a deliberate decision not to blind-port window decoration rendering onto the experimental, never-live-tested GPU render path.
2025-10-03Make the secondary-cursor sprite opt-in and expire stale entriessrdusr1-0/+21
Live report: a second cursor appeared uninvited and unusably (frozen, uncontrollable) on screen. Multi-cursor Phase 1 rendered one sprite per physical libinput pointer device that had ever reported a position, with no way to turn it off and no expiry - so a phantom device (a real mouse's side-button/scroll cluster enumerating as its own HID path is a common case) that reports once and never moves again left a frozen ghost sprite with nothing to control or dismiss it. Adds general.multi_cursor (default false, live-settable via `srd set multi_cursor <bool>`) and keys secondary_cursors to (Point, Instant) so both the recording side (udev/session.rs) and the render side (udev/render.rs) drop any entry older than SECONDARY_CURSOR_TIMEOUT (1.5s). The "agent controls a window without interrupting the user" use case this report also raised was never gated on this flag - that's Multi-cursor Phase 2's pinned virtual-pointer delivery, which never shows a visible cursor at all.
2025-09-26Fake (headless) monitors, and fix new windows all opening in one spotsrdusr4-8/+131
Two independent pieces landed together this pass - both real, both scoped, see docs/TODO.md for the full narrative on each: Fake monitors: a genuinely independent, additional wl_output with no DRM connector/CRTC behind it at all - distinct from srd.monitor.split (divides one real output's own placement rectangle). Researched niri's own Headless backend first (cloned at ~/reference-wms/niri): its render() never actually composites anything, a no-render stub for that project's test suite only. This one is real: it renders whatever is placed on it, on demand, whenever a zwlr_screencopy_manager_v1 client asks for a frame. New crates/wayland/src/udev/virtual_heads.rs (create/remove a real Output + global, render-on-demand for screencopy, integrated into platform.rs's monitors() as a genuine srdwm_core::Monitor so core placement/workspace code needs zero special-casing). New IPC/CLI: srd dispatch create fake-monitor <name> <w>x<h> / remove fake-monitor <name>. Core-side request queue in crates/core/src/manager/fake_monitor.rs. Placement bug, root-caused and fixed: every new window opened alone landed in the exact same spot, "not at all like Windows" (reported live). SmartPlacement::place tried a grid cell first, and grid's own cell count is existing.len() + 1 - with nothing else open (opening one app at a time, the ordinary case), that's always 1, so a 1x1 grid returns the same single cell forever regardless of session history. Cascade had the same bug in a second form (its own step was existing.len() % max_steps, also always 0 with nothing open). Fixed: WindowManager::next_cascade_step (a Cell - add_window's own target_monitor stays borrowed across the call) advances on every real placement and is never reset by a window closing; place() now skips grid entirely when nothing else is open, going straight to cascade, since grid's real job (dividing space among concurrent windows) has nothing to divide when there's no concurrency. Full workspace build/test/clippy clean (223 core / 141 wayland / 29 platform / 24 ctl / 28 config / 10 x11 tests, 0 failed, 0 clippy warnings), built and installed.
2025-08-29Core window manager: real fixes plus three new rule/placement primitivessrdusr5-61/+443
Several independent, real pieces landed in crates/core this shift - see docs/TODO.md for each one's full root-cause/verification narrative: - "Primary" monitor is now picked by which head sits at physical (0, 0) (the user's own configured anchor), not whichever connector DRM happened to probe first - fixes desktop icons and new-window placement landing on the wrong monitor depending on hotplug/probe order. - A new window's target monitor now prioritizes the pointer's own current monitor over the last-focused window's monitor, which goes stale the moment the user's attention moves to empty desktop, a panel, or a dock. - aspect_ratio window-rule action ("W:H") plus ResizeEdge::apply_aspect_ ratio: holds a floating window's aspect ratio through an interactive resize. The real, scoped "phone monitor" primitive - matches any VM/ emulator/scrcpy window by app_id, nothing Android- or VM-specific here. - general.phone_mode (WindowManager::phone_mode): a new window defaults to maximized instead of floating/tiled small, unless a rule explicitly floats it or sets maximized - the one placement default a phone-shaped screen actually needs. Exposed read-only via IPC so a shell panel can adapt its own chrome to the same signal. - input_pin.rs: the core half of pinning a virtual pointer to a specific window (Multi-cursor Phase 2) - a backend-agnostic request queue, same cross-boundary shape output_position_requests/lock_requested already use, since core has no real Wayland protocol object to reach into itself. Full workspace test suite covers all of the above (aspect-ratio resize math for every edge case, phone-mode default-vs-rule-override behavior, the pin-input request queue, the monitor-picking fixes).
2025-08-17Fix desktop icons v1 regressions: bar overlap, wrong order; add proper menussrdusr1-11/+7
Live testing found v1 genuinely broken, not just rough: 1. Icons weren't rendering reliably at all - ensure_desktop_icons only ever computed the grid's origin once, on whichever render pass happened to be first. AGS's own top bar registers its exclusive zone after that first pass, so origin got permanently baked in at the pre-bar geometry. Confirmed live via a temporary diagnostic log. Fixed by re-deriving origin from the primary monitor's current geometry on every call instead of just the first. 2. Fixed icons (Home/Computer/Trash) always sorted before real files -- confirmed wrong via direct question. The whole list now sorts alphabetically by label, case-insensitive, fixed icons included. 3. "Set as Wallpaper" was the wrong feature: removed entirely (DesktopMenuAction::SetWallpaper, general.wallpaper_command, is_image_path). The user wants that handled by their real file manager once opened, not reimplemented here. Also adds real menu functionality per "where are all the options": Rename (inline text edit, new CompState::renaming_icon field and keyboard redirect mirroring NativeLock::password's existing precedent), Delete (moves to ~/.local/share/Trash per the freedesktop.org spec, new trash.rs module, same-filesystem case, no confirmation - this is the reversible move-to-trash, not a permanent delete), Empty Trash on the Trash icon, and Open Terminal Here / Open in File Manager on the bare-desktop menu (new general.terminal config key). 133 wayland-crate tests (up from 106), full workspace build and clippy clean.
2025-08-15Fix a dragged/resized window rendering wrong on a different-scale monitor ↵srdusr2-11/+91
mid-gesture Reported live: moving a window onto the other monitor "looks very messed up". This machine's two real monitors have genuinely different scales (eDP-1 at 1.0, HDMI-A-1 at ~0.843) - the exact condition needed to expose this. WindowManager::update_drag/update_resize only corrected w.monitor once, at end_drag (update_resize never corrected it at all, not even at the end) - but state/geometry.rs::sync_geometry reads that field on every motion tick to pick which monitor's scale converts the client's physical size into the logical points xdg_toplevel::configure sends it. Crossing onto a different-scale monitor mid-drag kept every configure computed against the origin monitor's stale scale for the gesture's whole remaining duration, only self-correcting once the button came up. Both functions now re-derive w.monitor from which monitor the window's live geometry actually overlaps, every motion tick - the same Rect::overlaps lookup end_drag already used once at the end, now run continuously instead. end_drag's own fixup stays as a final-word safety net for a drag that starts and ends between two motion ticks. Does not close the related, already-documented gap where a client that doesn't speak wp-fractional-scale-v1 still mismatches once settled on a sub-1.0-scaled monitor - this only fixes the stale-during-the-gesture half. Two new tests, full workspace suite and clippy clean.
2025-08-15Add real desktop icons plus right-click desktop/icon context menussrdusr1-0/+39
Closes "right-click on bare desktop" - previously a true no-op, nothing rendered above the wallpaper at all. Requested directly: a real desktop "just like windows does" - Home/Computer/Trash plus one icon per real ~/Desktop entry, individually draggable with persisted grid positions, double-click to open, right-click menus (per-icon "Open" plus "Set as Wallpaper" for image files when general.wallpaper_command is set; bare desktop "New Folder"/"Refresh"). Architecture mirrors the existing context_menu.rs/snap_flyout.rs "compositor-owned floating UI" pattern: desktop_icons.rs (data model, grid layout, filesystem scan, hit-test), desktop_icons_state.rs (JSON persistence, same shape as monitor_layout.rs), desktop_menu.rs (the new right-click menu, reusing decoration::render_context_menu's existing rasterizer), state/desktop_icons.rs (CompState glue: rescan/select/drag/ open/persist), and a new decoration::render_desktop_icon rasterizer -- hand-drawn glyphs, since no PNG/SVG decoding capability exists anywhere in this workspace. Wired into both render loops (udev and winit) above the wallpaper and below every window, and into input/pointer.rs's button/ motion handlers for selection, drag, double-click, and both menus. Four new config keys: general.desktop_icons (default true - a directly requested, purely visual feature, unlike the opt-in-while-experimental general.gpu), general.file_manager, general.desktop_icon_single_click, general.wallpaper_command (all default off/empty). Deliberately out of scope for this pass, stated up front: move-to-trash and "Empty Trash" (destructive, no confirmation-dialog primitive to gate them on yet), filesystem watching, multi-select, per-mimetype icon art, icons on any monitor but the primary one. 124 wayland-crate tests (up from 106), full workspace build and clippy clean.
2025-08-10Make corner resize reachable at the button corner, and widen it everywhere elsesrdusr1-3/+11
Reported live: "even where decorations are corner i should still be able to corner resize, just its... hitbox... does not get in the way of the close icon" - the titlebar corner holding Close/Maximize/Minimize had no resize target at all, by design (competing with the close button was judged worse than losing that one corner). The BUTTON_CLUSTER_MARGIN strip between the button cluster and the frame's true edge was already dead space no button claims, regardless of button_count - its own top DECORATED_TOP_RESIZE_MARGIN rows now register as the diagonal corner (TopLeft/TopRight) instead of falling through to Top/Drag, without touching the button's own hitbox at all. Also requested: widen the other three corners' own resize zone, since a user reaching for a plain edge-resize instinctively aims for the middle of that edge, not its corner - a bigger corner zone doesn't compete with that instinct the way a bigger RESIZE_MARGIN would compete with ordinary content clicks near an edge. CORNER_MARGIN raised from 3 to 5 (18px to 30px at the default resize_margin). Updated one existing test whose own per-window resize_margin override (30px) now put its plain-edge test point inside the widened corner zone on a window too short for the two to stay apart - taller geometry, same edge point relative to center, no change to what it actually verifies. Added coverage for the new button-corner resize target on both sides, and for the dead strip's own non-corner rows still just dragging as before.
2025-05-28Add a real general.gpu config option for the GPU render pathsrdusr1-0/+18
SRDWM_GPU=1 was the only way to opt into the udev backend's GBM+EGL GPU render path - an env var, not a real config option, with no way to enable it from init.lua the way every other general.* flag works. WindowManager::gpu_enabled (plain bool, false by default - unlike rounded_corners_enabled's Option<bool>, GPU rendering has one unambiguous default regardless of which backend ends up connecting, so there's no "let the backend decide" case to preserve) is read from general.gpu in apply_general_settings, same as every other general.* key. gpu::probe now takes an explicit enabled: bool instead of checking the env var itself; udev/platform.rs's call site computes it as wm.gpu_enabled OR SRDWM_GPU=1, so the env var still works as a quick manual override for testing without touching config, on top of the new persistent option. Falls back to the existing software (Pixman) path exactly as before on any failure at any step (no GBM device, no atomic-modesetting support, a software-only EGL renderer, ...) - gpu::probe's own fallback behavior is unchanged, only how the initial enabled/disabled decision gets made.
2025-02-15Checkpoint: preserve all uncommitted rust-rewrite worktree worksrdusr7-29/+1000
Safety commit before reconciling this worktree with main, which has diverged with its own separate fixes today. Nothing here is reviewed or curated yet - this exists purely so none of this work can be lost to a git operation, disk issue, or worktree cleanup while that reconciliation happens.
2025-02-14Fix workspace switches undoing themselves within millisecondssrdusr1-8/+1
sync()'s per-tick platform.focus(id) re-assertion (added to keep real Wayland/X11 keyboard focus following core's own bookkeeping) ran unconditionally on every dirty tick, including when nothing about focus had actually changed. focus_window (core) has its own, separate side effect of switching to the focused window's workspace when it differs from the current one - correct when focus genuinely moves to a window on another workspace, but this call was never gated on focus having changed at all: switching workspace via activate_workspace left the still-focused window's own workspace field untouched, so the very next dirty tick's blind re-assertion of that same focus saw a mismatch against the just-changed current_workspace and switched straight back. Confirmed live via temporary core-side logging: two switch_workspace calls a few milliseconds apart, the second one undoing the first every single time, for every workspace switch that didn't also change which window was focused. Gated the re-assertion on the focused id actually changing since the last sync() call. Real focus-follows-real-platform-focus still happens on every genuine change, which is all the original fix needed.
2025-02-11Add temporary diagnostics for two live-reproduced bugssrdusr1-1/+8
1. A popup's xdg_popup.grab (Firefox's own right-click menu, concretely) receiving zero pointer input at all - no hover highlight, no click effect, not even dismiss-on-miss - logs whether grab_popup actually succeeds, since a silent failure there would explain exactly this. 2. srd dispatch activate_workspace returning {"ok":true} without ever changing the current workspace, confirmed via a raw socket request bypassing the CLI entirely. switch_workspace's own logic reads correct; logs its actual inputs/state to find out why the real process disagrees with it. Remove once both are resolved.
2025-02-03Fix focusing a minimized window not restoring itsrdusr2-0/+37
focus_window marked the target focused without clearing minimized, so a dock icon's Activate (or the plain "focus" IPC command) on a minimized window left it focused but still excluded from visible_windows/rendering - reads exactly like the click did nothing, since the window never actually reappears. Every focus_window caller gets the restore for free now. Added a Super+n keybind for minimize too, since none existed at all before this.
2024-11-30Accumulate core-crate additions: capture requests, focus/workspace fixes, ↵srdusr6-27/+449
test coverage Bundles several related changes to crates/core built up over this session rather than committed incrementally: - WindowManager::request_capture_workspace/drain_capture_requests (new manager/capture.rs) - backend-agnostic queuing for an off-screen workspace render, see the wayland-side commit for why this exists. - focus_window now switches workspace as a side effect when the target isn't on the current one, matching Hyprland's focuswindow convention (manager/focus.rs). - Assorted window/rules/theme field additions and their test coverage. Left less granular than the repo's usual one-purpose-per-commit convention deliberately: these accumulated across a long session without being committed as they landed, and are too entangled line-by-line to safely split apart now without risking mis-attributing changes to the wrong commit message.
2024-11-26Add Monitor::maximize_geometry: maximize covers a dock, still stops at a top barsrdusr2-2/+46
toggle_maximize previously targeted full_geometry outright (past every reserved zone), on an earlier request specifically about the dock - which also silently let it extend behind a top bar's zone, reported back as its own bug once live-tested. maximize_geometry is a third rect distinct from geometry (every zone) and full_geometry (none): full_geometry with only a top-anchored bar's exclusive zone subtracted back out. New test locks in dock-covered/bar-respected together.
2024-10-30Add srdwm's own native session-lock screen (blur, PAM auth)srdusr1-0/+51
A real ext-session-lock-v1 implementation drawn by the compositor itself, not a hand-off to an external locker process: a live-blurred background, PAM authentication on a background thread, and its own config surface (lock_config.rs) rather than hardcoded appearance.
2024-08-24Implement general.focus_follows_mouse/auto_raise; remove the rest as deadsrdusr1-0/+13
Auditing "clicking behavior and basics": general.focus_follows_mouse, general.mouse_follows_focus, general.auto_raise, general.auto_focus, the entire window.* namespace (8 more keys, a full duplicate of the same four plus remember_position/size/state), and general. smart_placement/border_width were all seeded into default_config() and documented in DEFAULTS.md, but none were read anywhere - srd.set()/ srd.get() on any of them silently succeeded while doing nothing. focus_follows_mouse is real, well-defined, and directly relevant to clicking basics - implemented it plus auto_raise (raise, not just focus, on hover) rather than just deleting the promise like the others. WindowManager gained focus_follows_mouse/auto_raise bools, wired from apply_general_settings the same way every other general.* flag is. handle_pointer_position now tracks whichever window (content or decoration) is under the pointer and, when the setting is on and that differs from the currently-focused window, focuses it through the same focus_window() free function every click-driven focus change already uses (real keyboard focus, not just core state) - skipped entirely while dragging/resizing or over a layer-shell surface, so the pointer sweeping over other windows mid-drag or hovering a bar can't steal focus from what's actually being manipulated. mouse_follows_focus (pointer warp on keybinding-driven focus change) and auto_focus (no clear distinct meaning beyond click-to-focus) stay unimplemented and are now undocumented rather than promised.
2024-08-22Add per-window resize-margin override (Hyprland's extend_border_grab_area)srdusr3-1/+25
MISSING.md had listed this as needing to touch srdwm_core::window:: hit_test's signature at every call site, including the honest-stub Windows/macOS backends - overstated on closer inspection: that shared function already takes a plain resize_margin: i32 parameter, agnostic to where the value comes from. The only real change needed was reading Window.resize_margin.unwrap_or(wm-wide default) instead of always the WM-wide value, at the single call site inside WindowManager::hit_test in core - no backend touched at all. Window.resize_margin: Option<i32>, WindowRuleActions.resize_margin to match, applied in add_window/reapply_rules_if_pending the same way opacity already is. Settable via a rule action or srd.window.set_resize_margin(n) on the focused window.
2024-08-09Fix a misleading workspace comment and drop four dead config keyssrdusr2-1/+11
visible_windows' doc comment claimed windows show "on the active workspace of whichever monitor they're assigned to" - the code never reads w.monitor at all; current_workspace is one flat value shared by every monitor, not per-output. Documented that explicitly on both the field and the method, since this is a real behavioral difference from Hyprland worth a reader actually seeing, not just an inaccurate comment to fix quietly. monitor.primary_workspace/monitor.workspace_count describe a per- monitor-workspace design that doesn't exist; workspace.auto_switch/ workspace.persistent were never wired to any behavior. All four were seeded into default_config() and documented in DEFAULTS.md, so srd.set()/srd.get() on them silently succeeded while doing nothing -- removed from both, matching the precedent already set by general. rounded_corners' deliberate absence from default_config for a different reason (backend-dependent default rather than unbuilt).
2024-08-08Fix clicks landing on a window hidden on another workspacesrdusr2-5/+39
WindowManager::hit_test/window_at filtered only by `!w.minimized`, never by workspace - but a window on a workspace that isn't current is not minimized, it's just not shown. Rendering (visible_windows/ visible_windows_front_to_back) already restricted to the current workspace; hit-testing didn't, so a click landing on where an invisible window's stale on-screen geometry happened to sit routed to that window instead of whatever was actually visible underneath. Reported live. Fixed by adding the same workspace check rendering already uses, plus a regression test with two identically-positioned windows on different workspaces.
2024-07-11Split crates/core/src/manager.rs (2048 lines) into manager/srdusr10-0/+2128
Pure reorganization, no behavior change - verified by diffing the function-name set before/after (identical 130 functions) plus a full cargo test pass. WindowManager's struct/field definitions, Default, new(), and the three trivial constructors (add_rule/register_layout/ available_layouts) stay in mod.rs; the rest of the single ~950-line impl block is split into one file per the section comments the file already had (monitors, windows, focus, winops, hittest, dragresize, workspaces, layout). Three methods called across section boundaries (monitor_for, windows_on_workspace, cycle_focus) went from private to pub(super) - Rust's privacy model doesn't let sibling submodules see each other's private items, only a defining module's own descendants. The ~1000-line test module moves to manager/tests.rs unsplit: its helpers (wm_with_monitor, two_monitors, monitor_with_dock) are shared across tests for every section, so splitting further would mean duplicating them or adding another shared-support file for little benefit.
