 ## Ground rules from the user
 
-- **Branch per big change, ask before merging.** New branch for each big change; merge into `master` only after explicit approval. "In main branch" or "merge directly to main" means commit straight to master. Small follow-ups in the same request can share a branch. **Push only when the user asks.**

 - **Never touch the user's real players' sound** (Cider, Firefox). Before any `island preset|output` call or volume change, check `amane ipc call island status` names a fake test player. Test audio goes to the inaudible null sinks.

+- **Desktop access is SSH only.** Don't probe the network, SSH keys or other hosts. If SSH fails, report it and wait. The user may be at the desktop while you test: if workspaces change or cards close by themselves, stop the on-screen tests.
 - **Leave the desktop clean** after testing: fake players and null sinks stopped, shell running without the frame log (see "After testing").
 - **Edit files with the patch/write tools, not scripts that rewrite files.** The user installs missing tools themselves. Scripts take instance values (hosts, names) as arguments.

+- **Blur strength is Hyprland's only** (`decoration.blur.*`; the user keeps size 1 and the layer rule's `ignore_alpha = 0.5`). The shell never sets it.
-- **D-Bus only for reading status.** Actions go through the CLIs: `iwctl` to join, scan and disconnect, `bluetoothctl` to pair and connect (the user had a D-Bus agent version reverted, `afe963d`). The one exception, chosen by the user: the shell serves `org.kde.StatusNotifierWatcher` and calls tray apps' dbusmenus. Ask before serving anything else on the bus.
+- **D-Bus mostly for reading status.** Actions go through the CLIs: `iwctl`, `bluetoothctl` (a D-Bus agent version was reverted, `afe963d`).

Ask before serving anything else.
-- **Never wake iwd by accident:** any D-Bus call to `net.connman.iwd` starts it (it then joins Wi-Fi and adds a route). Check `org.freedesktop.DBus.NameHasOwner` first; only talk to it while it has an owner.

Strings from other programs (SSIDs, device names, D-Bus metadata) go to `Command` args, never into `amane::spawn`/`output` (`sh -c`).

The panel morphs into its menus as one shape: Wi-Fi and Bluetooth maps (click to join/pair, right-click a saved network for its password, click the centre to search again), VPN list, sound outputs, Ethernet details with copyable addresses.

+- **Workspaces:** a removed empty workspace's slot shrinks and fades during the slide; a created one (`createworkspacev2`) grows in.
 - **Reserved space:** windows that aren't fullscreen stay below the bar (44 px).
-- **Settings** (branch `config-window`, merged 2026-10-15): `~/.config/amane/config.toml` holds all 184 shell settings with their help; the config window (`Magic Island settings`, a normal window; Esc closes it) edits them plus every Hyprland option. See Settings.
+- **Settings:** `~/.config/amane/config.toml` holds every shell setting with its help; the config window edits them plus every Hyprland option. Saves are serialised by `config::WRITTEN`, and the file watch skips the shell's own saves (an earlier race reset settings to defaults).
+- **Glass designs:** `appearance.surface.design` = solid / frosted / liquid, drawn by `surface::shell()` on every surface. The user keeps all three and may want more. The old branches `glass-base`, `design-frosted`, `design-liquid` (also on origin) are superseded; deleting them was asked, no answer.
 
-On 2026-10-13 the user tried the mouse-only parts (tray clicks, top-edge reveal, Copy buttons, PIN pairing): "All works". The agent itself only drives them over IPC.
+**Branch `side-pills`** (pushed, not merged; the user tries it first): two one-icon pills left of the island (AI, System) and two right (Home, Notifications); see Architecture and README "Side pills".
 
-**Glass designs** (`glass-base`, `design-frosted`, `design-liquid`, pushed, not merged): `glass-base` adds `src/surface.rs` (`shell()` draws the island, idle pill and workspace pill; with glass below 1 the open/close fade uses `.opacity()`, as a veil can't hide content on see-through glass) and a `glass` opacity; `design-frosted` (0.62, thin tint, hairline white rim, top sheen, soft black shadow) and `design-liquid` (0.4, specular gradient, light rim warming to `flame` on hover, accent glow) build on it. They branched from `036b326`, before the control centre and the settings, and read `glass` from `shell.conf`, which master no longer has: port them as settings (`appearance.surface.*`), not as a revived `shell.conf`. Measured 2026-10-09 (pill / open card GPU ms per frame): solid 1.6 / 3.3, liquid 2.2 / 3.3, frosted 2.9 / 3.3. `~/.config/hypr/windowrules.lua` has the glass layer rule (`^magic-.*$`, blur, `ignore_alpha = 0.5`).
+**On the desktop:** the agent-started shell (pid in `~/.cache/amane-remote-test/shell.pid`, stderr in `shell.err`) runs the `side-pills` build; the user's login shell was stopped with their approval. `config.toml` has `pills.ai.model = gemma4:e4b`, design frosted at 0.7. `~/.config/hypr/hyprland.lua` did not `require("amane")` (checked 2026-10-15), so Hyprland options set in the window are lost on a reload; the user was told.
 
-**On the desktop:** the agent-started shell runs the `config-window` build (pid in `~/.cache/amane-remote-test/shell.pid`, no frame log). `config.toml` was made from the old `shell.conf` (still there, unread). `~/.config/hypr/hyprland.lua` does **not** `require("amane")` yet (checked 2026-10-15), so Hyprland options set in the window are lost on a Hyprland reload; the user was told to add it. amane is not autostarted: after a reboot the user starts it.

 ## Constraints of Amane itself

+- Only `amane` and the Rust standard library: `amane compile` generates `Cargo.toml`, so no crates. External tools run as processes (`Command`, `amane::output`); HTTP is curl.
 - Amane redraws the whole window every frame, so every effect is paid at the frame rate.
 - Amane can only blur what the shell draws itself; frosting the desktop behind it needs a Hyprland layer rule.
 - `amane compile` saves `~/.cache/amane/amane-shell`; `amane run` starts it.

Views start with `theme::begin()` and draw with `theme::now()`; `theme::touch()` redraws every view. No theme file: `appearance.fallback.*`. `watch_file` watches the folder, so matugen's rename-over saves count. |

A popup click without a default action only hides it; the server's `click` would delete it. The server itself never expires notifications. |

-| `map.rs` | widget functions | The Wi-Fi/Bluetooth maps: nodes on an ellipse round the centre bubble (nearer = stronger), floating, lines, search rings. Sizes in `control.maps.*` (8 nodes at most: a 9th makes labels meet at 822 px; picked by simulating the drift). |
+| `theme.rs` `Theme` | Service, `watch_file` | 10 colours from `~/.config/amane/theme` faded on one `Animation`; also watches `config.toml`. Views start with `theme::begin()`, draw with `theme::now()`; `theme::touch()` redraws all. |

-- Background: one 150° three-stop gradient (`backdrop()`); with `cover_colors` the card blends to the cover's colours as it opens. White-alpha overlays (`appearance.overlays.*`, `CLEAR`) stay unthemed.
-- Hover: `hovering(spot)` eases a `Spot` over `appearance.motion.hover_ms`. Amane matches hover targets by index in the last frame, so a vanished button never hears the pointer leave: entering a spot fades all others, and `collapse()`/`set_menu()` drop stale highlights.

+## Side pills
+
+Two small one-icon pills sit left of the island and two right of it, on every monitor; they move outward while the island opens. A click morphs a pill into its card. Only one card is open across the shell: opening the island closes a card, and opening a card closes the island. Esc, the cross or a click elsewhere closes it.
+
+- **AI** (sparkle): a chat with a local Ollama model, `gemma4:e4b` at `http://localhost:11434` by default. Answers stream in through curl. When Ollama doesn't answer, the shell starts the OpenRC service with `doas rc-service ollama start` (`pills.ai.start_service`). Stop ends an answer and New chat starts over. Nothing leaves the machine.
+- **System** (pulse): CPU, GPU clock, memory, network and disk read/write as graphs over the last minute, plus the hottest sensors. Everything is read from `/proc` and `/sys`, so there is no process list. Processes opens `ghostty --class=amane.monitor -e btm` on the special workspace `monitor`; a second press shows or hides it.
+- **Home** (house): `~/.face` as the avatar (a person glyph until the file exists), a greeting, the date, a big clock, and Munich's weather now and for four days from open-meteo (no key). The month grid dots the days with events. The iCloud calendar shows the coming events once you sign in from the card with your Apple ID and an [app-specific password](https://account.apple.com). The password goes into the keyring through `secret-tool` (libsecret, so a Secret Service like gnome-keyring or KeePassXC has to run), never into `config.toml`. The calendar is read over CalDAV from `pills.calendar.server`, so other CalDAV servers work too.
+- **Notifications** (bell, with the unread count): Amane is the notification daemon (`org.freedesktop.Notifications`), so dunst must not run; it is commented out in `~/.config/hypr/autocmds.lua` (the old file is beside it as `autocmds.lua.before-amane-notifications`). Popups appear at the top right of the focused monitor with the app's icon or image, summary, body (simple markup) and action buttons. They time out by urgency (critical ones stay) and wait while the pointer is over them. A click runs the default action. The card lists the history, newest first; each entry's cross deletes it, and Clear all deletes everything. Mute turns popups off.
+
+`amane ipc call pods open|toggle ai|monitor|home|notifications [monitor]`, `close`, `ask <question>`, `processes`, `notices list|dismiss <id>|clear`, `status`. Sizes, colours, poll intervals, the city and its coordinates, the model and the popup timeouts are under Side pills and Notifications in the [settings](#settings).
+
+Left out on purpose: phone stats (iOS shares nothing Linux can read without extra daemons).
+
 ## Settings
 
 Every setting lives in `~/.config/amane/config.toml`: sizes, timings, text sizes, colours, poll intervals, equalizer presets and bands, the hotspot profile, the extra Sound output. The shell writes the file with every setting and its explanation the first time it starts (moving `cover_colors`, `transition_ms`, `hotspot` and `extra_output` over from an old `shell.conf`, which it no longer reads). Saving the file applies it at once; a line left out takes its default, and a line the shell can't use is listed at the top of the config window. The font and the cava bar count take effect on restart.
