+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What this repo is
+
+Documentation and planning for a GNOME → Hyprland migration on Fedora 43. No build system, no tests, no executables. The actual system configuration lives in `~/.dotfiles/` (separate Forgejo repo), managed with GNU Stow.
+
+## Key locations outside this repo
+
+| What | Where |
+|------|-------|
+| Hyprland config | `~/.dotfiles/hypr/.config/hypr/hyprland.conf` |
+| DMS source configs | `~/.dotfiles/hypr/.config/hypr/dms/` |
+| Symlink target | `~/.config/hypr/` → symlinked via `stow hypr` |
+| Hyprland log | `~/.cache/hyprland/hyprland.log` |
+| Dotfiles remote | `git@forgejo.swansoncloud.com:jared/dotfiles.git` |
+
+## Hyprland configuration
+
+**Installed version:** 0.51.1 (Fedora 43). See `docs/hyprland/version-history.md` before applying patterns from the official wiki — the wiki tracks git HEAD, which is ahead of the installed version.
+
+**Window rule syntax for 0.48–0.51** (not the block syntax shown in current wiki):
+```
+windowrule = match:class classname, effect
+windowrule = match:class classname, match:title titlepattern, effect1, effect2
+```
+Do NOT use `^(...)$` wrapping — Hyprland 0.51 rejects it as "Invalid rulev2". Use plain names or bare regexes (e.g. `^org\.gnome\.` for a prefix match).
+
+**Block syntax** (`windowrule { }`) is 0.52+ only — do not use until after a Fedora upgrade.
+
+## Docs structure
+
+- `docs/window-manager/` — migration plan, phased progress log, keybindings cheatsheet
+- `docs/hyprland/` — version-aware Hyprland config reference; update these when Hyprland is upgraded
+
+## Project status
+
+Phases 0–3 complete (install, config, dotfiles integration). Phase 4 (first successful Hyprland login and smoke tests) is in progress. Phase 5 (tuning) is deferred.
+
+Known workaround in place: `hyprpolkitagent` replaced with `lxpolkit` due to Qt 6 ABI issue on Fedora 43.
+
+## Hardware
+
+- AMD Vega iGPU (primary display, Wayland)
+- NVIDIA RTX 3060 dGPU (unused — `akmod-nvidia` intentionally not installed)

+# Layer Rules — Hyprland 0.48–0.51
+
+Layers are non-window surfaces: status bars, wallpapers, launchers, notifications.
+
+## Syntax (current: 0.48–0.51)
+
+```
+layerrule = match:namespace ^(regex)$, effect
+```
+
+Use `hyprctl layers` to find a layer's namespace.
+
+## Effects
+
+| Effect | Notes |
+|--------|-------|
+| `no_anim` | Disable animations |
+| `blur` | Enable blur |
+| `blur_popups` | Blur popups too |
+| `dim_around` | Dim everything behind layer |
+| `animation style` | Override animation style |
+
+## Our rules
+
+```
+layerrule = match:namespace ^(quickshell)$, no_anim
+layerrule = match:namespace ^dms:.*, no_anim
+```
+
+## 0.52+ block syntax (not yet installed)
+
+```
+layerrule {
+    match:namespace = ^(quickshell)$
+    no_anim = on
+}

+# Hyprland Version History — Breaking Config Changes
+
+Focus: syntax changes that affect our config. Not a full changelog.
+
+## Installed: 0.51.1 (Sept 2025)
+
+## windowrule syntax timeline
+
+### Pre-0.48 (old — do not use)
+```
+windowrule = float, ^(class-regex)$           # v1: positional class, no prefix
+windowrulev2 = float, class:^(regex)$         # v2: explicit class: prefix
+```
+
+### 0.48–0.51 (CURRENT — use this)
+Both `windowrule` and `windowrulev2` keywords work, but `windowrulev2` is deprecated.
+Use `windowrule` with `match:` prefixed props. Patterns are plain strings or bare regexes —
+do NOT use the old rulev2 `^(...)$` wrapping; Hyprland 0.51 rejects it as "Invalid rulev2".
+```
+windowrule = match:class classname, effect
+windowrule = match:class classname, match:title titlepattern, effect1, effect2
+windowrule = match:class ^org\.gnome\., rounding 12   # prefix regex — anchor ok, no outer ()
+```
+Props can come in any order relative to effects.
+Boolean effects: `float`, `tile`, `pin`, `no_initial_focus` (no "on" suffix needed)
+Value effects: `rounding 12`, `opacity 0.9`
+
+### 0.52+ (not yet installed — do not use until upgrade)
+Block syntax introduced:
+```
+windowrule {
+    name = optional-name
+    match:class = ^(regex)$
+    float = yes
+    rounding = 12
+}
+```
+Anonymous flat block syntax also available:
+```
+windowrule = match:class regex, effect value
+```
+
+## layerrule syntax timeline
+
+### Pre-0.48 (old)
+```
+layerrule = no_anim, ^(namespace)$   # positional namespace
+```
+
+### 0.48–0.51 (CURRENT — use this)
+```
+layerrule = match:namespace namespacename, no_anim
+```
+Same rule as windowrule: plain string or bare regex, no `^(...)$` wrapping.
+
+### 0.52+ (block syntax)
+```
+layerrule {
+    match:namespace = ^(regex)$
+    no_anim = on
+}
+```
+
+## Other notable changes
+
+| Version | Change |
+|---------|--------|
+| 0.48 | `windowrulev2` deprecated; new `windowrule` with `match:` prefix |
+| 0.48 | `layerrule` updated to use `match:namespace` prefix |
+| 0.52+ | Block syntax for `windowrule` and `layerrule` |
+
+## Upgrade checklist
+
+When upgrading Hyprland:
+1. Check `hyprland --version` (or `rpm -q hyprland`)
+2. Scan release notes for "windowrule", "layerrule", "deprecated"
+3. Update this file
+4. Update the comment in `hyprland.conf` window rules section

+# Window Rules — Hyprland 0.48–0.51
+
+Reference for the syntax currently used on this machine.
+See [version-history.md](version-history.md) for what changes on upgrade.
+
+## Syntax (current: 0.48–0.51)
+
+```
+windowrule = match:class classname, effect
+windowrule = match:class classname, match:title titlepattern, effect1, effect2
+```
+
+Patterns are plain names or bare regexes. **Do NOT use `^(...)$` wrapping** — Hyprland 0.51
+rejects it as "Invalid rulev2" (that was the old windowrulev2 class-matching format).
+Anchors are fine without outer grouping: `^org\.gnome\.` matches any GNOME reverse-DNS class.
+
+Multiple props and effects can be on one line, comma-separated, any order.
+
+## Match props (filtering)
+
+| Prop | Example | Notes |
+|------|---------|-------|
+| `match:class` | `match:class firefox` | Window class (app ID) |
+| `match:title` | `match:title Picture-in-Picture` | Window title |
+| `match:xwayland` | `match:xwayland true` | XWayland windows only |
+| `match:float` | `match:float true` | Currently floating |
+| `match:fullscreen` | `match:fullscreen true` | Currently fullscreen |
+
+Use `hyprctl clients` to find a window's class and title.
+
+## Static effects (applied once at window open)
+
+| Effect | Example | Notes |
+|--------|---------|-------|
+| `float` | `float` | Force float |
+| `tile` | `tile` | Force tile |
+| `fullscreen` | `fullscreen` | Force fullscreen |
+| `maximize` | `maximize` | Force maximize |
+| `rounding` | `rounding 12` | Pixel rounding (overrides global) |
+| `no_initial_focus` | `no_initial_focus` | Don't steal focus on open |
+| `pin` | `pin` | Show on all workspaces (float only) |
+| `move` | `move 100 200` | Position (float only) |
+| `size` | `size 800 600` | Size (float only) |
+| `workspace` | `workspace 2` | Open on specific workspace |
+| `monitor` | `monitor 1` | Open on specific monitor |
+| `suppress_event` | `suppress_event maximize` | Ignore window events |
+
+## Dynamic effects (re-evaluated on change)
+
+| Effect | Example |
+|--------|---------|
+| `opacity` | `opacity 0.9` or `opacity 0.9 0.7` (active inactive) |
+| `border_color` | `border_color rgb(FF0000)` |
+| `no_blur` | `no_blur` |
+| `no_shadow` | `no_shadow` |
+| `no_anim` | `no_anim` |
+| `no_focus` | `no_focus` |
+| `idle_inhibit` | `idle_inhibit always` |
+
+## Our rules (reference)
+
+```
+# Force-tile apps that default to floating
+windowrule = match:class gnome-control-center, tile
+windowrule = match:class pavucontrol, tile
+
+# Force-float small utilities
+windowrule = match:class gnome-calculator, float
+windowrule = match:class org\.gnome\.Nautilus, float
+
+# Rounded corners for all GNOME apps (prefix match)
+windowrule = match:class ^org\.gnome\., rounding 12
+
+# Multi-prop (steam toasts)
+windowrule = match:class steam, match:title notificationtoasts, no_initial_focus, pin
+
+# Firefox PiP
+windowrule = match:class firefox, match:title Picture-in-Picture, float
+```
+
+## Finding window class/title
+
+```bash
+hyprctl clients | grep -E "class:|title:"
+# or run this in a terminal, then open the window:
+hyprctl -j clients | jq '.[] | {class, title}'
+```

+## 2026-04-19 — Phase 4: windowrule syntax fix
+
+- On first Hyprland login: config errors on all windowrule lines — "Invalid rulev2 found: match:class ^(...)$"
+- Root cause: `^(...)$` wrapping was the old windowrulev2 regex format; Hyprland 0.51 explicitly rejects it even with the new `windowrule` keyword. Correct 0.51 syntax uses plain names or bare regexes with no outer grouping parens.
+- Fixed all windowrule and layerrule patterns in hyprland.conf (stripped `^(...)$`; kept `^org\.gnome\.` prefix anchor without outer group).
+- Updated docs: CLAUDE.md, docs/hyprland/version-history.md, docs/hyprland/window-rules.md all corrected to show actual 0.51 syntax.
+- Noted: solopasha COPR still at 0.51.1 for Fedora 43; upstream latest is 0.54.0. Upgrade deferred until COPR catches up.
