It is not a scratch pad. It is not a cache. Once a document lands here it is never deleted and never silently rewritten — it is corrected forward, with a changelog entry, the way a real research institute corrects the record. + +This file is the specification. Every document under `research/` must conform to it exactly. If a future research session cannot make a source or a conclusion fit this specification, the specification gets amended first (with a changelog entry below), and only then does the document get written — the rule is never quietly bent for one entry. + +## 1. Why this exists + +Research happens, gets used for one decision, and then evaporates — the next person (or the next session of the same agent) re-derives it from scratch or, worse, never finds out it was already settled. This archive exists so that: + +- every external claim this project's design relies on has a traceable source, a date, and an honest confidence level; +- a conclusion (a decision actually made because of research) is recorded separately from the raw source material that informed it, so "what we found" and "what we decided" never get smeared into one document that's impossible to audit later; +- the next person — human or model — can answer "have we already looked into this?" by reading an index instead of repeating a web search. + +## 2. Directory layout + +``` +research/ + README.md <- this specification (the only file allowed at the root besides INDEX.md) + INDEX.md <- the living registry of every subject, every document, and archive-wide statistics + / + .md <- one file per external source consulted for this subject + conclusions/ + .md <- one file per distinct conclusion/decision drawn from this subject's sources +``` + +**Subject** is a research topic, not a single query — "sqlite-rag-hybrid-search" or "agent-memory-recency-tracking", not "search query #4". A new research task that is clearly a continuation of an existing subject adds documents into that subject's existing folder; it does not fork a near-duplicate subject. When genuinely unsure whether something is a new subject or a continuation, prefer the existing subject — subject sprawl is a worse failure mode than a slightly-too-broad subject. + +**Slugs** are lowercase, hyphen-separated, ASCII, no stop words beyond what's needed for uniqueness, derived from the source's domain plus a short topic fragment (e.g. `mem0-introducing-memory-decay.md`, `arxiv-2310-08560-memgpt.md` for a numbered arXiv paper — the arXiv id goes in the slug verbatim, hyphenated, because it's the only stable identifier a paper has). Two different pages on the same domain get distinguishing fragments, never `-2`, `-3` suffixes — a suffix number tells a future reader nothing about what's inside the file. + +## 3. The three document types + +There are exactly three kinds of document in this archive. Nothing else is permitted at the file level; a new need gets solved by extending one of these three, with a changelog entry here, not by inventing a fourth ad hoc. + +### 3.1 Source Dossier (Tier 1 — independently analyzed) + +Used when the source was actually read and synthesized in enough depth to state real findings, pros, cons, and a relevance judgment. This is the default, full-weight document. Required sections, in this exact order: + +```markdown +# + +## Metadata + +| Field | Value | +|---|---| +| Institute | Molodetz Institute — Research & Retrieval Division | +| Subject | | +| Document type | Source Dossier | +| Tier | 1 | +| Source title | | +| Source URL | | +| Source publisher / author | | +| Source type | | +| Source date (published) | | +| Date researched | | +| Researched by | tai (agent), model: Claude Sonnet 5, on behalf of retoor | +| Research method | | +| Confidence | | +| Status | | + +## Summary + +Two to five sentences. What does this source actually claim. No hedging filler — if the source is thin, the summary says so plainly rather than padding it. + +## Key findings + +Bullet list of concrete, attributable claims. Each bullet should be something a reader could independently go verify against the source. + +## Pros / strengths + +What this source gets right, or what makes it a good argument for its position. + +## Cons / limitations / caveats + +What's missing, unproven, vendor-biased, outdated, or contradicted elsewhere. A Tier 1 dossier with an empty cons section is a red flag that it wasn't read critically — write "none identified, see confidence rating" explicitly if that's genuinely the case, rather than leaving the section out. + +## Relevance to tai + +Why this mattered to the actual engineering decision at hand. A source can be excellent and still irrelevant; say so if that's the case. + +## Changelog + +| Date | Change | +|---|---| +| | Initial dossier created. | +``` + +### 3.2 Source Citation Card (Tier 2 — listed, not independently analyzed) + +Used for a source that turned up during research (a search result, a related link) but was **not** independently read in enough depth to responsibly claim pros, cons, or specific findings. This tier exists specifically so volume of sources consulted is never achieved by quietly inflating what's actually known about each one — it is better, and more professional, to log a source honestly as "seen, not analyzed" than to fabricate a dossier for it. Required sections: + +```markdown +# + +## Metadata + +| Field | Value | +|---|---| +| Institute | Molodetz Institute — Research & Retrieval Division | +| Subject | | +| Document type | Source Citation Card | +| Tier | 2 | +| Source title | | +| Source URL | | +| Source type | | +| Date researched | | +| Researched by | tai (agent), model: Claude Sonnet 5, on behalf of retoor | +| Research method | Search aggregator result listing (not independently opened or quoted) | +| Confidence | Not independently verified | +| Status | Active | + +## Why it's here + +One or two sentences: what search surfaced it, and why it looked potentially relevant to the subject. + +## Changelog + +| Date | Change | +|---|---| +| | Logged as consulted-but-not-analyzed. | +``` + +A Tier 2 card may later be promoted to a Tier 1 dossier if someone actually reads the source in depth — promotion means rewriting the file to the Tier 1 template and adding a changelog line noting the promotion and its date, never duplicating it as a second file. + +### 3.3 Conclusion Document + +A conclusion is a decision or a standing judgment the project actually made *because of* research — never just a restatement of one source. It lives in `/conclusions/` and is written only once the underlying research is done. Required sections: + +```markdown +# Conclusion: + +## Metadata + +| Field | Value | +|---|---| +| Institute | Molodetz Institute — Research & Retrieval Division | +| Subject | <subject-slug> | +| Document type | Conclusion | +| Tier | N/A | +| Date decided | <YYYY-MM-DD> | +| Decided by | retoor, advised by tai (agent, Claude Sonnet 5) | +| Status | <Active \| Superseded by <link> \| Reverted> | +| Confidence | <High \| Medium \| Low> | + +## Question / problem statement + +What question was this research actually trying to answer. One paragraph, no padding. + +## Conclusion + +The actual decision or standing judgment, stated as a plain declarative claim a reader could act on without reading anything else. + +## Supporting sources + +Linked list of the Tier 1 dossiers (and, where genuinely load-bearing, Tier 2 cards) in this subject that back this conclusion, each with a one-line note on what it contributed. + +## Alternatives considered and rejected + +What else was on the table, and the specific reason each alternative lost. "We didn't think of it" is a valid entry if true; inventing a more flattering rejection reason is not. + +## Risks / open questions + +What could make this conclusion wrong later, and what would have to change for it to be revisited. + +## Action taken + +What actually happened as a result (a feature shipped, a design rule adopted, a decision deferred on purpose). If nothing was built yet, say so explicitly — a conclusion is allowed to be "we now know what to do, we have not done it yet." + +## Changelog + +| Date | Change | +|---|---| +| <YYYY-MM-DD> | Initial conclusion recorded. | +``` + +## 4. The standing rule (also stated in [AGENTS.md](../AGENTS.md#research-rule)) + +**Every time research is conducted for this project — a web search, a round of searches, reading documentation to settle a design question — it is written into this archive before the research is considered "done," not as an afterthought.** Concretely, every research task produces: + +1. a subject folder (new, or an existing one reused); +2. one document per source actually consulted, Tier 1 if it was read and synthesized, Tier 2 if it was only seen in a result listing — no source gets skipped just because it turned out to be low-value; a low-value source is itself a finding, recorded honestly; +3. a conclusion document for every decision the research actually produced, if any was reached; +4. an updated [INDEX.md](INDEX.md) — the subject's row, the global counts, and the "Recent activity" log all get updated in the same pass, never left for later. + +A research task that produces no written archive entries did not happen, as far as this project is concerned — if it isn't here, it gets redone and re-verified the next time someone needs it, which is the exact waste this archive exists to prevent. + +**There is no "this one doesn't really count" exception, ever.** This rule was broken once already — the research behind `tai_test.py` (eight `WebSearch` calls on pty/asyncio/process-testing patterns) was skipped on the judgment that it was "informal engineering reference, not a design decision," a call made silently and alone, never surfaced to anyone, and wrong. "It's just engineering," "it's too minor," "I'll remember to do it after I finish the actual task" are exactly the thoughts that preceded that miss, not reasons it was fine. If a research task feels like an exception, that is the signal to archive it anyway, not a reason to skip it — and if there's ever real ambiguity about whether something should be archived, that ambiguity gets stated out loud (to the user, or as a visible note in the response) instead of resolved unilaterally and invisibly. A decision nobody can see is a decision nobody can catch. + +## 5. Quality bar + +- **No fabricated specifics.** A Tier 1 dossier's "Key findings" must be things actually said by the source, not plausible-sounding inferences dressed up as findings. When synthesis, not direct reading, is the basis for a claim (e.g. a web-search tool's own summary of a page), that's still fine for Tier 1 as long as it's a faithful restatement — it only drops to Tier 2 when there isn't enough independent content to responsibly summarize at all. +- **Confidence ratings are honest, not reassuring.** "Low" confidence on a real finding is more useful to a future reader than "High" confidence dressed up to look thorough. +- **Dates are never guessed silently.** "Unknown — not stated" is a correct value for a metadata field; a made-up date is not. +- **Corrections are forward, not silent edits.** If a later research pass finds a dossier was wrong, the file gets updated and the changelog gets a new row explaining what changed and why — the old claim doesn't just vanish from history. +- **One subject, one home.** Before creating a new subject folder, check `INDEX.md` for an existing one that already covers the topic. +- **`Tier` is its own metadata field, not text buried in `Document type`.** Every document's metadata table has a standalone `Tier` row (`1`, `2`, or `N/A` for a Conclusion) precisely so tier can be greped/filtered on directly — `grep "^| Tier | 1 |"` — instead of matching a parenthetical inside a longer string. `Document type` states only the document kind (`Source Dossier`, `Source Citation Card`, `Conclusion`); it never repeats the tier. + +## 6. Changelog (of this specification itself) + +| Date | Change | +|---|---| +| 2026-10-09 | Initial specification written, alongside the first two subjects (`sqlite-rag-hybrid-search`, `agent-memory-recency-tracking`) backfilled from the same day's research. | +| 2026-10-09 | Split `Tier` out into its own metadata field (`1` / `2` / `N/A`) instead of a parenthetical inside `Document type`, so it can be filtered on directly.

Thank you to all who provided feedback and filed issue reports on the first preview. I’ve fixed a lot of issues and added quite a few missing features. Here are the essentials: Source tarball . Build and install instructions are in the README. Please pay careful attention to build and runtime prerequisites. Issue tracker . Search the issue tracker first in case someone else has already filed a similar issue. If not, and you file a new one, be sure to fill out every part of the issue template. Git repository . If you’ve found an issue, it would be helpful if you could ensure it’s still present on git main. You can also try any fixes and features I’ve added since the release.

Again, please take a look at the README for runtime dependencies. xfwl4 will build and start without those runtime dependencies met, but some functionality may not work if you have older versions of some Xfce components and libraries.

Principle + +Keep `xfwm4` on X11 untouched indefinitely. Add `xfwl4` (Rust + Smithay, from scratch, not xfwm4 fork) as the Wayland path. Reason per Xfce team: xfwm4 is X11-first, refactor risks X11 regressions; two codebases = zero risk to X11. + +## 2. Target layout + +- X11 session (unchanged, default-safe): `startxfce4` → `xfce4-session` → `xfwm4` + panel + desktop. Desktop file: `/usr/share/xsessions/xfce.desktop`. +- Wayland session (new, opt-in → later default): compositor is session root → `xfwl4` launches `xfce4-session` via `xdg-session-management` / autostart. Desktop file: `/usr/share/wayland-sessions/xfce-wayland.desktop` with `Exec=startxfce4 --wayland [xfwl4]`. +- Interim fallback (4.20/4.22 era): `startxfce4 --wayland labwc|wayfire` where distro lacks xfwl4. Ship both entries: `xfce-wayland.desktop` (xfwl4) + `xfce-wayland-labwc.desktop` (fallback, hidden when xfwl4 present). + +## 3. Session startup change + +- X11: `xfce4-session` is root. Wayland: compositor must be root (owns outputs, input, sockets). So `startxfce4 --wayland` execs compositor first, compositor spawns `xfce4-session` as client. +- Fix `xfce-wayland.desktop` per-distro (Arch/Debian field bug): ensure it calls compositor wrapper that autostarts `xfce4-session`, not bare compositor. +- LightDM: set `user-session`/`autologin-session=xfce-wayland` under `[Seat:*]`; GDM/SDDM: rely on wayland-sessions dir. SDDM preferred where LightDM lacks Wayland greeter support. +- Env: `XDG_SESSION_TYPE=wayland`, `GDK_BACKEND=wayland,x11`, `QT_QPA_PLATFORM=wayland;xcb`, `MOZ_ENABLE_WAYLAND=1`, `EGL_PLATFORM=gbm` (NVIDIA, see §4). + +## 4. NVIDIA & drivers + +- Require: DRM KMS enabled, Mesa `libgbm.so.1 ≥ 21.2`, `egl-wayland ≥ 1.1.8` (≥ 1.1.9 for wl_drm GPU selection), Xwayland ≥ 21.1.3 with GBM path (commit 5daf42b4). +- xfwl4/Smithay uses GBM backend; EGLStreams legacy is out. Proprietary + nvidia-open both go through GBM. Debug with `__NV_GBM_TRACE_ENABLED=1`. +- Non-GBM / old cards: keep X11 session as supported path; document in release notes, do not block Wayland default on machines that probe-fail (DM fallback rule §6). +- Field gaps to carry: `qt5/6-wayland` + `xdg-desktop-portal{,-gtk,-wlr}` + `swaybg` wallpaper + cursor-theme workaround until xfdesktop Wayland wallpaper/cursor lands. + +## 5. Config parity (same visible behavior) + +- Reuse `xfconf` keys + `xfwm4` settings dialogs for xfwl4 (official plan). No new config format. +- Ship `labwc`-parity `rc.xml` mapping during transition (`~/.config/xfce4/labwc/rc.xml`, placement=center, workspace count) so labwc fallback feels like xfwm4. +- Keyboard/mouse/display dialogs: require xfce4-settings ≥ 4.21.2, xfdesktop ≥ 4.21.0. Mouse/touchpad-on-Wayland still open — gate Wayland-default on its fix. + +## 6. Packaging (Debian/Fedora/Arch) + +- New packages: `xfwl4`, `xfce4-session-wayland` (desktop files + wrapper). Deps: rustc ≥ 1.90, meson ≥ 0.57, libseat, libinput ≥ 1.28, libdrm, libgbm, libdisplay-info ≥ 0.3, xwayland, xfconf ≥ 4.21.2, libxfce4ui ≥ 4.21.4, themes from xfwm4 (hard dep — xfwl4 refuses start without xfwm4 themes). +- Do not touch `xfwm4`/`xfce4-session` X11 files. Conflicts: none. Recommends: `xwayland, xdg-desktop-portal, swaybg, qtwayland`. +- DM rule: if `xfwl4 --check` (DRM/GBM probe) fails → hide wayland entries, boot X11 entry.

For each, the exact Wayland protocol status, current xfwl4/Smithay support, required changes in xfce4-panel, xfdesktop, xfce4-settings, xfce4-power-manager, and the minimal code changes needed must be stated. + +## Conclusion + +xfwl4 already implements the core protocol stack (xdg-shell, layer-shell, ext-workspace, ext-foreign-toplevel-list, wlr-foreign-toplevel-management, xfce-private extensions, ext-idle-notify, wlr-output-power-management, xdg-session-management, session-lock, xdg-activation, screencopy). The remaining gaps are therefore not "protocol absent" but "protocol capability deliberately unused or compositor-internal state not yet exposed": workspace create/remove/assign, toplevel state beyond maximize/close, session restore on the client side, panel plugin embedding, and keyboard/mouse/brightness handling. Full parity requires closing all of these; none is a one-line change, and several are permanent limitations imposed by Wayland's design (no foreign-surface embedding, no standardized brightness keys). + +### 1. Workspaces (ext-workspace-v1) + +- Protocol status: `ext-workspace-v1` is wayland-protocols staging, v1. Advisory: every create/remove/assign/activate/deactivate request may be ignored. No toplevel-to-workspace association in the base protocol; that lives in `xfce_foreign_toplevel_management_private_v1`. +- xfwl4/Smithay: implements `src/protocols/ext_workspace.rs`. Advertises a single workspace group for all outputs (Xfce has one workspace set). Advertises only `Activate | Deactivate` capabilities. Honors `commit` batching. Ignores `create_workspace`, `remove`, `assign`. Emits `output_enter`/`output_leave` as outputs change. +- Required changes: + - xfce4-panel pager: hide create/remove/rename actions unless the compositor advertises the capability; treat activation as advisory and wait for `state` events. + - xfdesktop: no workspace creation UI; rely on settings dialog. + - xfce4-settings: Workspaces dialog still needs the unmerged `workspaces-dialog-libwindowing` branch of xfwm4; until merged, workspace count/grid is not configurable on Wayland. +- Minimal code: gate pager actions on `ext_workspace_handle_v1` capabilities; route workspace count changes through xfconf and have xfwl4 read them (currently compositor-side state). Estimated: medium, depends on xfwm4 branch merge. + +### 2. Foreign toplevel management + +- Protocol status: `ext-foreign-toplevel-list-v1` (staging, v1) is enumeration only (identifier, title, app_id, done, closed). State/actions come from `wlr-foreign-toplevel-management-unstable-v1` (unstable, v1) and Xfce's private `xfce-foreign-toplevel-management-private-v1` (shaded, skip_pager, skip_tasklist, sticky, above, below, demands_attention; move, resize, move_to_output, move_to_workspace, get_icon_pixels). +- xfwl4/Smithay: implements all three stacks (`ext_foreign_toplevel_list.rs`, `wlr_foreign_toplevel_management.rs`, `xfce_foreign_toplevel_management.rs`). Added move/resize and horizontal/vertical maximize in 4.21.1. Reports activated state correctly (fixed 4.21.1). +- Required changes: + - xfce4-panel tasklist: use private protocol for workspace association, shade, sticky, always-above/below, attention, icons. Fall back to base list under non-Xfce compositors (labwc) where only maximize/close/minimize are available. + - xfdesktop window menu: same fallback; middle-click menu and minimized-icon view remain partial. + - xfce4-settings: none (compositor-side). +- Minimal code: tasklist already wired to libxfce4windowing >=4.20.7; ensure runtime dep floor enforced. Estimated: low (dep-gated), but feature depth varies by compositor. + +### 3. Idle notify (ext-idle-notify-v1) + +- Protocol status: `ext-idle-notify-v1`, staging, v2. `get_idle_notification` (inhibitor-aware) and `get_input_idle_notification` (input-only, v2). Timeout 0 valid. Notification only; no dim/blank/suspend action. +- xfwl4/Smithay: `src/core/handlers/ext_idle_notify.rs` wraps Smithay `IdleNotifierState`. Available. +- Required changes: + - xfce4-power-manager: map Xfce idle alarms (blank, lock, suspend) onto `idled`/`resumed` events; use inhibitor-aware variant for screen blanking and input-only variant for user-activity tracking. Presentation mode maps to `wp-idle-inhibit-v1`. + - xfce4-settings: none. +- Minimal code: power-manager Wayland backend already uses the protocol; remaining work is policy mapping and graceful degradation when global is missing (warn, not crash). Estimated: medium. + +### 4. Output power management (wlr-output-power-management-unstable-v1) + +- Protocol status: `zwlr_output_power_manager_v1`, unstable wlr, v1. Binary on/off. No standby/suspend mode. No GNOME/Mutter support. Only outputs in compositor space. +- xfwl4/Smithay: `src/backend/udev/handlers/wlr_output_power_management.rs`, including fallback to clearing CRTCs if legacy DPMS fails. +- Required changes: + - xfce4-power-manager: use for DPMS on Wayland (already does); handle `failed` event (exclusive control, unsupported output, output gone). + - xfce4-settings display: none. +- Minimal code: mostly done; ensure failure paths degrade to "no DPMS" rather than errors. Estimated: low. + +### 5. Layer-shell (wlr-layer-shell-unstable-v1) + +- Protocol status: `zwlr_layer_shell_v1`, unstable wlr, v5. Layers background/bottom/top/overlay; anchor; exclusive zone; margins; keyboard interactivity none/exclusive/on_demand (v4); set_layer (v2); set_exclusive_edge (v5); popup parenting. No GNOME/Mutter support. No stable replacement. +- xfwl4/Smithay: `src/core/shell/layer.rs`. Focus/tooltip fixes in 4.21.1. +- Required changes: + - xfce4-panel: uses gtk-layer-shell; relies on exclusive zones for struts and maximized-window avoidance. Autohide replacement via viewporter is in progress (labwc issue #2129); anchoring preserved. + - xfdesktop: background surface on background layer. + - xfce4-settings: none. +- Minimal code: keep gtk-layer-shell dependency; verify compositor implements exclusive zones correctly. Estimated: low for panel placement, medium for autohide polish. + +### 6. xdg-session-management-v1 + +- Protocol status: `xdg-session-management-v1`, wayland-protocols staging (released 1.48). Manager/session/toplevel-session handles. Reason enum (launch/recover/session_restore). Per-toplevel names. `restored` event before first configure. restore_toplevel must precede first commit. State set is compositor-defined; no guarantee of survival. +- xfwl4/Smithay: `src/core/handlers/xdg_session_management.rs`. Persistent `sessions.yaml`, 2s debounced save, ~9 month expiry. Restores geometry, saved geometry, workspace id, output EDID, window state, per-workspace stacking serials. +- Required changes: + - xfce4-session: pass a stable session id; xfwl4 is the session root (not xfce4-session), so startup/logout/lock/restore semantics must be reworked. + - Applications: name toplevels; use `xdg_` interfaces not old `xx_` draft. Firefox-style apps must adopt. + - xfce4-settings: none. +- Minimal code: client-side adoption is the blocker, not compositor. Estimated: high (cross-project coordination); compositor side largely done. + +### 7. Panel embedding (external plugins) + +- Protocol status: no Wayland equivalent of XEmbed/GtkSocket/GtkPlug. freedesktop wayland-protocols issue #74 closed and locked. Workaround: external plugins as layer-shell surfaces with geometry synchronized over D-Bus (xfce4-panel, MR !103, landed post-4.18). +- xfwl4/Smithay: supports layer-shell; panel runs as layer-shell surface. No compositor-side embedding. +- Required changes: + - xfce4-panel: keep D-Bus geometry sync; internal plugins (modules) run in-process and are unaffected; external plugins use workaround with possible dissociation on panel move. + - xfdesktop: none. + - xfce4-settings: none. +- Minimal code: accepted limitation; document as permanent regression vs X11. Estimated: no further code; parity definition must be adjusted. + +### 8. Input / keyboard / mouse / brightness handling + +- Protocol status: no standardized brightness-key or input-settings protocol. `xfce-input-device-list-private-v1` is read-only (reports settings/defaults/supported values; no change requests). xfwl4 implements `xfce_accessibility_private_v1` (find_pointer). Keyboard layout switching, global shortcuts, and accessibility remain open upstream gaps. +- xfwl4/Smithay: `src/protocols/xfce_input_device_list.rs`, `src/core/handlers/xfce_accessibility.rs`. Tablet configuration added 4.21.1. No brightness-key handler found in source tree. +- Required changes: + - xfce4-settings: keyboard/mouse/touchpad dialogs must drive configuration through xfconf; compositor reads xfconf and applies. Display settings already ported. + - xfce4-power-manager: brightness control via backlight (sysfs) works independently of compositor, but brightness keys must be handled by xfwl4 and forwarded or acted upon. Currently a compositor-side gap. + - xfce4-panel: brightness plugin works via power-manager D-Bus, not compositor. +- Minimal code: xfwl4 needs a brightness-key handler (currently absent) that either adjusts backlight directly or emits a D-Bus/xfconf signal. Estimated: medium; plus upstream protocol work for input settings. + +### Cross-cutting: compositor-internal settings + +Keyboard, mouse/touchpad, workspaces, screen margins, brightness/power keys, display mirroring/VRR are compositor state. They cannot be fixed by porting xfce4-settings dialogs; they need xfwl4-side implementation plus a settings UI path. This is the largest structural gap and is tracked in the parity gap register. + +## Supporting sources + +- `wayland-app-ext-workspace-v1.md`: ext-workspace contract, capability model, advisory semantics. +- `wayland-app-ext-foreign-toplevel-list-v1.md`: minimal enumeration base. +- `wayland-app-ext-idle-notify-v1.md`: idle notification contract and inhibitor split. +- `wayland-app-wlr-layer-shell-unstable-v1.md`: layer-shell contract. +- `wayland-app-wlr-output-power-management-unstable-v1.md`: DPMS contract. +- `hoyon-xdg-session-management-v1.md`: session restore contract. +- `github-xfwl4-repository.md`: file-level evidence of what xfwl4 implements; brightness-key absence. +- `github-xfce-wayland-protocols.md`: private protocols including input device list (read-only) and foreign-toplevel extensions. +- `xfce-dev-external-panel-plugins-wayland.md`: panel embedding workaround rationale. + +## Alternatives considered and rejected + +- **Make the panel an embedding compositor.** Rejected: explicitly avoided by xfce4-panel authors; too large and fragile. D-Bus geometry sync is the accepted path. +- **Wait for a standardized foreign-surface embedding protocol.** Rejected: freedesktop issue #74 is closed and locked; no upstream path exists. +- **Treat wp-idle-inhibit / brightness as xfce4-power-manager concerns only.** Rejected: brightness keys are compositor input events on Wayland; power-manager cannot see them without compositor forwarding. +- **Assume ext-workspace create/remove will arrive soon.** Rejected: staging and advisory; xfwl4 deliberately ignores them; pager must degrade gracefully. + +## Risks / open questions + +- Several protocols are staging/unstable; capability sets and versions may change, requiring client rework. +- Compositor-dependent feature depth (labwc vs xfwl4) means the same panel/plugin code behaves differently; testing matrix must cover both. +- Brightness-key handling has no upstream standard; xfwl4 must implement privately, coupling to its input stack. +- Session restore depends on application adoption of xdg-session-management, which is outside Xfce's control. + +## Action taken + +Recorded as the Prompt 5 gap register for the zucht project. No code changes.

Duplicate names raise `name_in_use`; adding the same toplevel twice raises `already_added`. +- Session ids and toplevel names are UTF-8 and limited by the maximum Wayland message size (around 4 KB). +- The compositor has no required set of states to remember: "The compositor should remember as many states as possible for surfaces in a given session, but there is no requirement for which states must be remembered." +- Cache eviction is an implementation detail, and clients must tolerate a previously known session no longer existing. + +## Pros / strengths + +- Finally gives Wayland a standardized session-restore contract, which Xfce needs for xfce4-session parity. +- The reason enum is a useful policy hook: not every restoration should resurrect stacking order. +- Per-toplevel names let applications restore a specific window rather than guessing by creation order. +- Explicit `restored` event gives clients a synchronization point before the first configure. + +## Cons / limitations / caveats + +- The state set is compositor-defined, so "session restore" means different things in xfwl4, KWin, and other compositors. +- No guarantee that a session survives eviction; clients must handle missing state. +- The protocol does not restore application internal state, only window management state. +- It does not solve application relaunch.

Because Wayland has no X11 `GtkSocket`/`GtkPlug` (XEmbed) mechanism, Gaël Bonithon implemented a non-native workaround: external plugins run as layer-shell surfaces whose geometry is synchronized with the panel over D-Bus rather than by the compositor. The approach was chosen specifically to avoid "the embedding compositor route", i.e. making the panel itself a mini-compositor. + +## Key findings + +- The chosen mechanism keeps the existing socket/plug abstraction and process management/IPC, adding a D-Bus layer to synchronize socket and plug geometries, with an abstraction layer distinguishing X11 and Wayland implementations. +- External plugins are layer-shell windows (`zwlr_layer_shell_v1`), not embedded surfaces. The compositor never manages the plug/socket overlay internally. +- Because the overlay is not compositor-managed, plugins can visibly dissociate from the panel when the panel moves, though the effect is described as "reasonable". +- The approach depends on how the compositor implements layer-shell: "it also depends on the way the compositor implements the layer-shell protocol". +- Some XEmbed graphical limitations disappear (e.g. background image issue #107), because the plug background can be made transparent. +- The author references freedesktop wayland-protocols issue #74 ("Allow embedding foreign wl_surfaces") and notes it is not only closed but locked, leaving little hope for a standardized embedding protocol. +- The MR referenced is xfce4-panel !103, intended to land after the Xfce 4.18 release. +- Internal plugins (compiled as modules) are unaffected; only separately-process external plugins use this path. + +## Pros / strengths + +- Reuses the existing external-plugin process model and IPC, so crash isolation of external plugins is preserved. +- Avoids a large architectural change (making the panel a partial compositor). +- Transparent backgrounds remove an old XEmbed rendering artifact. +- A single abstraction layer keeps X11 and Wayland code paths maintainable together. + +## Cons / limitations / caveats + +- Not a true embedding: geometry sync is approximate and plugins can lag/dissociate during panel movement. +- Compositor-dependent behavior; not all compositors implement layer-shell identically (exclusive zones, margins, popups). +- No process-level surface parenting: there is no Wayland equivalent of XEmbed, so the compositor cannot enforce plug/socket clipping. +- The freedesktop issue requesting foreign-surface embedding is closed and locked, so there is no upstream path to native embedding. +- Internal vs external plugin distinction remains; internal plugins still run in-process and cannot be isolated. + +## Relevance to tai + +This is the definitive statement of why panel plugins remain a degraded experience on Wayland and why "embedding compositor" is a permanent non-goal.

These directly block panel tasklists, xfdesktop window icons, pagers, screenshot of the active window, and color-managed output. +2. **Session model.** On Wayland the compositor must be the session root instead of xfce4-session; xdg-session-management and window/workspace restore are still goals/gaps. Any parity plan must include startup, logout, lock, and restore semantics, not just window management. +3. **Compositor-internal settings.** Keyboard, mouse/touchpad, workspaces, screen margins, brightness/power keys, and display mirroring/VRR are compositor state. They cannot be fixed by porting xfce4-settings dialogs; they need xfwl4-side implementation plus a settings UI path. +4. **Desktop integration regressions.** GtkSocket/GtkPlug plugin embedding is gone; the layer-shell + D-Bus workaround reproduces the structure but not process isolation. Panel pager thumbnails, taskbar state control beyond maximize/minimize/fullscreen, xfdesktop minimized-icon view and middle-click menu, and systray/StatusNotifier coverage are still incomplete. +5. **X11 compatibility layer.** XWayland is in scope, but X11 apps still need WM_HINTS/Motif icon handling, unminimize, override-redirect, restacking, and focus fixes. These are actively being closed (several landed in 4.21.1) but remain a compatibility backlog. + +Standing judgment: zucht must track parity against this register and against xfwl4's live issue list, and must keep the X11/xfwm4 path fully functional as the fallback.

"Reaching X11 feature parity is not yet our target." +- No Xfce release is currently committed to a complete Wayland transition: "It is not clear yet which Xfce release will target a complete Xfce Wayland transition (or if such a transition will happen at all)." +- Agreed guidelines: do not depend on XWayland; no xsettings; use smithay (not wlroots/libmutter) for the compositor; keep panel and xfdesktop runnable as separate components; avoid libgnome-desktop; keep X11 compatibility for the foreseeable future; keep xfwm4 X11-only with xfwl4 as the Wayland counterpart. +- Core components marked "yes" for Wayland (4.21 or git master): exo, libxfce4ui, libxfce4util, thunar, xfce4-appfinder, xfce4-panel, xfce4-session, xfce4-settings, xfconf, xfdesktop, xfce4-power-manager, tumbler, garcon, thunar-volman, xfce4-dev-tools. xfwm4 is "not planned". +- xfce4-panel Wayland port is MR !103, is wlroots-based, and targets Labwc/Wayfire. GtkSocket/GtkPlug external plugin embedding is gone; current workaround reproduces it with layer-shell plus D-Bus, and keeping plugins out-of-process would require the panel to become a partial embedding compositor. +- xfdesktop Wayland port is MR !43. Workspaces need an X11/Wayland abstraction (candidate: wlr-workspace-unstable-v1); enumerating toplevels (window list menu, desktop window icons) needs another (candidate: wlr-foreign-toplevel-management-unstable-v1). +- xfce4-settings: xsettings counterpart in MR !104; display settings port in MR !112. Keyboard, mouse and workspace settings are internal to the compositor and have no protocol, so they cannot be ported as ordinary settings dialogs. +- xfce4-power-manager: no real Wayland counterpart for brightness management; keyboard-driven power actions (brightness keys, suspend key) are not restored because only the compositor can handle them. +- Applications: xfce4-terminal (dropdown needs layer-shell), mousepad, xfce4-notifyd, xfce4-taskmanager (no libwnck app icons, no identify-window, no systray icon), xfce4-mixer, ristretto, catfish, xfburn, parole (player window not embedded, no systray icon), xfce4-screenshooter (active window unsupported), xfmpc, xfce4-dict, gigolo, xfce4-panel-profiles are listed as working. xfdashboard (crashes on startup), xfce4-screensaver (port done in !28 but blocked on experimental libwlembed), xfce4-volumed-pulse (key bindings fail) and xfce4-xkb-plugin (not portable near-term, placeholder) are listed as not working. +- All four listed Thunar plugins (archive, media-tags, shares, vcs) are marked working. +- Panel plugins: every listed plugin is "yes" except xfce4-xkb-plugin ("no"). Caveats: clipman relies on wlr-data-control and still needs StatusNotifier; docklike needs libxfce4windowing 4.19.4; eyes does not follow the pointer outside the panel; windowck needs libxfce4windowing 4.20.6. The table's "yes" means "doesn't crash", not full X11 behavior. +- Screenshot support depends on compositor protocols: wlr-screencopy (fallback), ext-image-capture-source-v1 and ext-image-copy-capture-v1; rectangle selection uses gtk-layer-shell; active-window capture is not possible with current protocols and may need a custom protocol. +- Testing guidance: use master or latest development release; NVIDIA needs Nouveau or proprietary >= 495 with GBM; labwc/wayfire were the original targets, "nowadays xfwl4 is our target compositor"; `startxfce4 --wayland` and wayland-sessions desktop files exist, but the instructions are marked outdated and pending review. + +## Pros / strengths + +- Maintained by the project itself, with explicit MR/issue links for most claims. +- Separates "supported" from "feature complete" honestly; panel plugin note explicitly warns "yes" only means "doesn't crash". +- Names the architectural blockers (GtkSocket/GtkPlug, compositor-internal input settings, missing workspace/toplevel protocols) rather than only listing symptoms. + +## Cons / limitations / caveats + +- A living wiki page with no publication date; the "last modified 2026-08-19" stamp is the only temporal anchor, and sections are visibly stale (testing section says "Outdated information below, review is pending"). +- Tables lag reality: they reflect "4.21 or git master" and are not a statement about xfwl4 4.21.1 behavior. +- No quantitative measures, no test matrix, no hardware coverage. +- "yes" for panel plugins is a crash test, not a behavior test. + +## Relevance to tai + +This is the baseline state document for the zucht goal. It establishes three constraints that shape all later design work: xfwl4 is the official Wayland compositor target; X11/xfwm4 must stay first-class indefinitely; and several xfwm4 behaviors cannot be reproduced without compositor-private protocols or embedding-compositor work.

The choice is declared not open for debate. +- Only xfwm4 is being replaced/rewritten.

Instead, it will be written from scratch in rust, using smithay building blocks. The first attempt at creating an Xfce Wayland compositor involved modifying the existing xfwm4 code to support both X11 and Wayland in parallel. However, this approach turned out to be the wrong path forward for several reasons: Xfwm4 is architected in a way that makes it very difficult to put the window management behavior behind generic interfaces that don't include X11 specifics. Refactoring Xfwm4 is risky, since it might introduce new bugs to X11. Having two parallel code bases will allow for rapid development and experimentation with the Wayland compositor, with zero risk to break xfwm4. Some X11 window management concepts just aren't available or supported by Wayland protocols at this time, and dealing with those differences can be difficult in an X11-first code base.
